How to Use Self Drilling Wall Anchors

When it comes time to hang thing from the walls of your home, whether it be a TV or simply photographs is large picture frames, you will find that you are going to need some wall anchors in order to assist you in your task. Wall anchors do just what they are named for.  They are inserted into the wall and act as secure points to either attach screws nails. They help increase the strength of your nails and screws, and help them hold the weight of various objects. An added benefit of the wall anchors is that you are not going to be drilling your screw directly into the wall itself and thus creating the possibility of striping the secure wall matter away.

Step 1 – Mark Your Points

As with all projects, it is important to be as prepared as possible for the task at hand. After you have secured all the necessary materials, you need to decide where you are going to be drilling your holes. Make sure to make your measurements exact so that you don’t end up drilling and making more holes into your walls then is necessary.

Step 2 – Pre-Drill Your Holes

Once your measurements and markings are made, be sure to pre-drill a very small hole into the wall. This will make drilling the self-drilling wall anchor a very easy task for you. Drill in only about a quarter of an inch into your dry wall and then remove the screw.

Step 3 – Ready Your Self-Drilling Wall Anchor

You will notice that self-drilling wall anchors are simply screws that have a plastic coating that appears to cover it. When you drill into the wall, the plastic coating is actually drawn back and creates a large hold in the wall itself. This secures the nail into place. Now make sure that you have properly aligned your self-drilling wall anchor with the hole that you are going to be driller.

Step 4 – Drill Through Your Dry Wall

Now with everything set, simply use your motorized drill and drill the wall anchor through your wood. Make sure that it goes all the way through. Once the top of the screw becomes flush with the wall, continue to drill. This will cause the plastic coating on the backside of the screw to pull away and to fill the hole that you have just created. This secures your screw in place and will hold it much longer than had you simply drilled using a plain screw.

One of the greatest benefits from using a self-drilling wall anchor is that you are going to save a lot of time when it comes time to do a large amount of drilling. If you were to not use a self-drilling wall anchor, you would find that first you would have to drill in a regular anchor, and then have to drill in a second screw through the wall into the anchor itself. While this task may only take 30 seconds to complete, it is still 30 seconds that you have wasted. Using a self-drilling wall mount, you are merely had to drill one time and one time only and then you are finished.

Advantages of Hollow Bar Anchors

The hollow bar anchor system is ideal for Tie Back Anchors; Ground Anchors, Grouted Anchors, Injection Grouting, Grout Blankets, Soil Nailing, Ground Stabilsation and Rock Coring.

Advantages:

  • Three (3) times greater productivity than conventional systems.
  • Fast progress of construction due to drillling, anchor installation and grouting in a single operation
  • No casing is required in collapsing ground conditions.
  • Neither separate anchor installation nor removal of casing and drill rods are necessary
  • Similar installation methods for all ground conditions
  • The hollow core not only serves for flushing during drilling, but also for grouting the anchors
  • Grout injection technique continually scours and flushes the sides of the drill hole, enhancing mechanical connection to

    the soil.

  • Anchor bars are made from a high quality, high yield, low carbon steel, which does not suffer from hydrogen

    embrittlement or stress corrosion cracking.

  • The grout body provides simple, permanent corrosion protection.
  • Very low creep characteristics of the bar obviate the need for re-stressing.
  • Flexibility in length due to the utilization of couplers
  • Can be extended by couplings on site if ground conditions do not match the S.I. information.

High Performance Rock Bolt Grout (HPRG)

A grout suitable for cable bolting must have some expansion to enhance bond and anchorage. It must provide protection to the bolts and cables in aggressive ground conditions, have an early gel time and achieve a rapid strength development for early support.

CBG-HPRG is specially formulated using cement, fillers and special additives to fulfil the above criteria.

Uses

With modern mining techniques slowly replacing the use of steel work with other means of support, the need for a high strength bolting grout becomes ever more prevalent.

It is well known that rock is relatively strong in compression and weak in tensile, shear and flexural strengths and often requires reinforcing. Further to this, excavated rock and coal surfaces often deteriorate on exposure. Bolting overlapping zones can safely and securely contain rock and coal within the vicinity of the bolts.

The effective anchorage and bonding to the rock by the roof bolts, cable bolts and dowels is achieved by grouting. Thus the selection of the right grout is of paramount importance.

Some introduction of steel sheet piling

Steel sheet piling is a hot-rolled structural shape with interlocks on the flange tips. The interlocks permit individual sections to be connected to form a continuous steel wall which is earth-tight and water resistant. Because it is readily available and transportable, steel sheet piling is in many cases a fast and economical solution to an owner’s need for a durable, long lasting wall system.

Applications are far-reaching, and include, for permanent construction, retaining walls, bulkheads, bridge abutments, graving docks, cut-off walls, mooring dolphins and pier protection cells. Common uses also include temporary structures, such as trenches, cofferdams for building excavations, bridge piers, and lock and dams on the inland river system. At the end of the project, the steel sheet piles can be extracted, and the steel reused.

Hot rolled steel sheet piling is an engineered product meeting one of several applicable ASTM specifications. These specifications, combined with the steel sheet piling producer’s quality control programme, provide a quality product which is ductile, durable and long-lived. In fact, construction in West London, UK, recently unearthed steel sheet piles over 80 years old.

When pulled from the native wet soil, the piles were so well preserved, the original mill marks could be seen. Steel pilings in continuously submerged conditions tend to have relatively low corrosion rates, because oxygen levels decrease with depth. Steel pilings are also a zero-waste product: after extraction, they can be reused or 100% recycled.

FRP sheet pile for construction

Sewers are an important infrastructure that supports our comfortable living environment. However, in cities where buildings are built closely together with a lot of traffic, it is difficult to construct tunnels (sewer pipes and public utility conduit) by opening and cutting street pile. Therefore, the “shield construction method”, with which they use excavators called “shield machines” starting with shafting and excavate underground to create tunnels, is rapidly starting to become popular in recent years.

However, shafting requires (1) Pressure insertion of sheet pile (steel) around the tunnel to prevent soil from collapsing and groundwater seeping through, (2) Improvement of the ground by injecting cement milk in order to stabilize the surrounding ground, and (3) “Ground breaking process”, with which they cut the steel sheet pile with a burner to run the shield machine. Such a construction method takes time and efforts, and the ground breaking process also involves safety-related risks.

Reduction of ground improvement and ground breaking work with the newly developed “carbon FRP sheet pile”

DIC has been providing FRP (Fiber Reinforced Plastics) bathtubs and artificial marble kitchen counters, which utilize sophisticated resin processing technologies, to housing equipment manufacturers. We also have manufacturing experience with construction materials, such as FRP for temporary construction, etc. Based on this knowledge, we launched the development project of new sheet pile that improve the workability of the shield construction method in cooperation with the Zenitaka Corporation. In 2012, DIC succeeded in developing “carbon FRP sheet pile” with the same level of strength as steel sheet pile by layering strong and light carbon fibers and glass fibers and impregnating/curing resin.

By incorporating these sheet pile into shafting, we no longer need the improvement of the ground by injecting cement milk or the process to manually cut sheet pile. Shield machines can excavate tunnels by directly cutting through FRP sheet pile. This not only improves work safety but also enables significant reduction of the construction period and resource conservation.

DIC plans to proactively propose the shield construction method utilizing the “carbon FRP sheet pile” for sewer construction, etc. in urban areas based on the evaluation of workability, etc. through demonstration experiments in the field by the Zenitaka Corporation.

Plastic Sheet Piling

PVC sheet piles have a high mechanical endurance. The maximum wall height is up to 3 meters. Plastic piles would suit for:

  • Shoring up banks;
  • Strengthening ditches;
  • Shoring foundation pits;
  • Protection of groundwater;
  • Building of piers.

The application of plastic piling is the vinyl pile device of the fence ditches, trenches, strengthening of coastline, building of bridges, overpasses and trestles as well as hydraulic erection (docks, moorages, hydroelectric stations, sluices and so on) and construction for the storage of solid and liquid industrial wastes.

The vinyl piles are so projected that it is easy to form internal and external curves along the natural coast. Vinyl sheet piles are made of rigid polyvinyl chloride, which is modified with substances that facilitate recycling: impact viscosity modifiers, thermal and UV stabilizers, as well as mineral filler.

Piles like steel sheet piles are connected with each other with special keys. Such structures are especially durable and are extremely durable and have very high mechanical characteristics (with a 50 years’ guarantee).

The sheet piling is normally capped off with either a wood or concrete cap and a walkway. It would be good to use around lake front property as well to control shore erosion. Plastic piling provides flood prevention.

Plastic Piling has a number of benefits over traditional steel, timber or concrete piling; mainly cost, durability, ease of handling and environmental. Plastic sheet piling holds up well to the sea and brackish water in and around the bays.

They protect your construction for a long time, because the material is resistant to: bio-corrosion, rust, fractures, cratches, abrasion, seawater, harmful radiation (UV).

Simple Guide On How To Install Sheet Pile

Sheet pile installation can’t be done by piling contractor while there is specialist contractor for sheet pile to do the installation. Here is a rough installation procedure for sheet pile:

1) Pile Driving Equipment

Before starting driving sheet pile, a few equipments have to be prepared such as driving hammers and jetting equipment. The driving energy for hammers shall be recommended by the manufacturer so that it’s applicable to relevant sheet pile. While jetting equipment shall have a minimum of two removable or fixed jets of the water or be a combination of air a water type.

2) Placing and Driving

After preparing all the sheet pile driving equipments, sheet piles can be started to place on the location that shown in the construction drawings. Temporary wales, templates, or guide structures have to be carried on to ensure the sheet pilings are placed and driven to the correct alignment.

After the sheet piles is set on place, jetting machine will be starting to driving the sheet piles. Sheet piles have to be driven with the proper size of hammer and by approved methods to ensure no damage to the sheet piles and proper interlocking throughout their lengths. A protecting cap shall be employed on the tops of sheet pile to prevent damage during driving with hammer.

3) Cutting-Off and Splicing

After driving the sheet piles into the ground, if contractor find that they need additional penetration, splicing or jointing works will be carried on. Driving works will be done again for the sheet piles until it reaches its’ limit on the ground. After this, excessive of sheet pile will be cutting-off and removed from the site. All cutting-off work must be done in a neat and workmanlike manner for safety purpose.

4) Inspection of Driven Piling

The contractor shall inspect the interlocked joints of driven sheet piles extending above ground. If contractor find out that the sheet piles are out of interlock, then the sheet piles have to be removed and replaced with a new sheet pile.

5) Pulling and Redriving

After the inspection of driven piling, another similar process has to be carried on which is called pulling and redriving. The contractor shall pull selected sheet piles to determine the condition of the underground portions of sheet piles. If contractor found any damages to the extent that its usefulness in the structure is impaired, then the sheet piles have to be removed and replaced with a new sheet pile.

The use of plastic sheet piles in the construction industry today

Plastic sheet piles have been available in this country for over five years and have been used in other parts of Europe for over 20 years. So with the dramatic rise in the cost of steel, why is there such a reluctance to try an ‘innovative’ alternative to steel sheet piles.

From discussions with various organisations within the UK, there have, unfortunately, been instances where companies undertaking the installation have been unable to drive the piles to the required depth, have broken the piles during the installation process or have failed the design capability. However, there are companies in the UK who have successful experience of the supply and installation of plastic sheet piles. It is not realistic to say that plastic sheet piles can be used in all instances where steel sheet piles can, but there are a great many times where they could be used and are not.

The main problems facing plastic sheet piles are:

  • Failed projects travel round the industry far quicker and far more reaching than the successful ones.
  • Regulatory bodies are nervous about using innovative materials until they have been tried and tested.
  • Some consultants are unaware of the products and their design capacities.
  • Contractors prefer to use the ‘old faithful’ as they have experience with the products, the sub-contractors or installing them themselves.

The key areas where plastic sheet piles could be used to both cost and other advantages within the railway are:

  • Retaining walls/coffer dams – some plastic sheet piles have design parameters. They can therefore be used as a specifically designed steel sheet pile would be. With their lighter weight, non conductivity and corrosion resistance there are many areas where these would be superior to a steel sheet pile.
  • Embankments – To stabilise the toe of an embankment in inaccessible areas and where there are limitations on the size of plant.
  • Temporary works – the plastic sheet piles to be used as steel would be to retain temporary excavations and be propped where necessary. The pile can be retracted depending on the soil conditions. Especially useful where electrical arcs are could be an issue.
  • Formwork – using plastic sheet piles are cheaper than the standard wood formwork, easy to install and lightweight.

Why should the railway industry be using plastic sheet piles?

Key advantages are:

  • Non-conductive
  • Lightweight materials – manually handled
  • Lightweight plant – alleviates stresses on embankments and allows for easier accessibility
  • Up to 30% cheaper than steel
  • Manufactured from recycled plastics

Composite and vinyl sheet piles, bulkheads and sea walls

Our construction and optimum design guarantees high durability and makes possible diverse, very universal application.

Composite vinyl sheet piles can be used as aesthetic and solid sea walls, bulkheads, they secure river banks as well as are a great solution for road construction and in many other situations.

Amongst the advantages of the system the complexity of solutions and the durability of all of the elements are one of the most important. We are also proud of aesthetic look, light weight, incombustibility, as well as safety of our sea walls or bulkheads. Moreover, thanks to high resistance to rust or scratches, our system is superior to traditional solutions made e.g. out of steel.

The combination of modern material, well-thought design and high quality production process results in manufacturing piling which meets even the highest expectations.

Benefits of vinyl and composite piles

There are several reasons to choose vinyl, composite sheet pile. Amongst the most important, the following should be mentioned:

  • low costs – in comparison with traditional solutions, both the initial as well as long-term costs (of e.g. repairs, replacement of damaged elements etc.) are much smaller,
  • resistance – not only with respect to their durability, but also when it comes to UV resistance,
  • simple installation – quick and easy, with the use of simple machinery, allows to limit the time of work as well as the initial costs,
  • high aesthetics – their appearance does not change over time, the color remains the same, thus all of the sea wall, bulkheads etc. remain very aesthetic throughout the years.

The main difference, resulting in diverse application of vinyl sheet piling and its composite alternative, is the maximum height of protective construction created with their use. Since the latter can be installed to create much higher bulkheads, sea walls and other, similar constructions than the former one, it is much more often applied near coast line. Apart from that, with both solutions you get all of the benefits described above.

Vinyl Sheet Pilings for Cost-Effective Construction

The construction industry has all along been a booming industry with a lot of innovations taking place all the time. Nowadays, we see a lot of vinyl sheet piling system used as an alternative to hardwood and steel sheet piling. Vinyl has its own advantages as it is extremely durable, cost effective and weather resistant. Furthermore, vinyl will not be affected by rodents, or salt or fresh water and it is environment friendly. All these positive features make vinyl ideal material for sheet pilings.

Vinyl sheet piling has been gaining popularity in the construction market in recent times. Vinyl has become the preferred choice of engineers and contractors who use it for bulkheading and seawalls. Now with more and more attention being paid to vinyl, some suppliers have created the biggest vinyl box profile in the world allowing for even better benefits for contractors and engineers.

Cutoff walls call for extreme precaution. It is essential to contain hazardous materials to prevent seepage into ground water. Flood control structures are equally important as life and property need to be safeguarded from violent storms. While no product can provide 100 percent guarantee to hold up against a storm, advanced vinyl decking material may provide a better chance of survival.

20151105Sheet Piles for Cut Off Wall

A new vinyl sheet pile section is now being manufactured to serve the marine and civil industries. They are expected to offer more effective performance in cutoff, flood control, bulkhead and seawall applications.

Vinyl sheet pilings reduce seepage through the interlocks, allowing minimal use of sealants. Vinyl sheets can be installed at all places where steel sheet piling can, with the use of proper equipment. The light weight, durability and low cost of vinyl sheet piling make it a viable cost effective solution for projects all over the world.

It needs to be noted that vinyl is an inert material and hence does not dissolve when it comes into contact with many frequently occurring chemicals. Besides, no poisonous substances are released into the ground or the water.

A sheet piling was hitherto made of metal and wood but the scenario has changed with more and more people opting for vinyl sheet pilings for its many advantages including low price.

The components of a vinyl seawall are manufactured conforming to some very rigid standards without giving room for errors and the advantage is vinyl does not fade like wood.

The rampant use of vinyl sheet piling all over has made other traditional materials like wood, steel, concrete, and aluminum outdated. Traditional materials had all along lacked performance guaranteed as they were found breaking down almost immediately in a salt-water environment. The reason people are choosing vinyl sheet piling is that it is lot more cost effective than the type of materials used earlier.

As a family owned and operated company, Gulf Coast Treated Piling and Timbers has been manufacturing and supplying high quality building materials including vinyl sheet pilings nationwide for over 35 years.
