There are several types of steel piles?

  1. Steel pipe pileCompared with other steel piles, steel columns in many aspects have their unique advantages, such as connecting long welding, single pile bearing capacity, bending stiffness, penetrating ability and other aspects.
  2. Shaped steel pileI-type and H-type steel piles are more common cross-sectional shape. In the horizontal load, the vertical load of the load can be applied to type I and H-type steel piles. Steel pile in a variety of stratigraphic penetration ability, in addition, its disturbance to the formation of relatively minor, is part of a pile of soil. If the spacing of the driven piles is small at the center, H-shaped steel piles may be used to replace the other piles to prevent surface damage due to piling operations, such as lateral crowding, uplift and the like.
  3. Steel sheet pileCompared with other steel piles, steel columns in many aspects have their unique advantages, such as connecting long welding, single pile bearing capacity, bending stiffness, penetrating ability and other aspects.

What are steel piles and when can they be used?

If anything, galvanized screw steel piles are versatile. They can be used in many different applications – from decks to docks, fences to signs, additions and garages and, in fact, for any structure that doesn’t require a full basement. Used in conjunction with full foundations in unstable soil conditions, steel piles can even assume the role of deep footings.

Basically, steel piles are a big screw, made of galvanized steel with a helical flange that not only helps to insert the pile, but also helps secure it into the ground. By using a mini-excavator with special attachments, a drill can enter the ground while measuring the load bearing capacity of the soil. This ensures precisely addressing the foundation engineering requirements right at the time of installation. With the variety of soil conditions in Muskoka, and the steel pile’s status as an engineered product, it can be used with rock, swamp and everything in between.

Steel piles are a viable alternative to concrete sono tubes, useful for situations where precision is needed for levelling and where ground disturbance is to be kept to a minimum. Piles are also a simple solution for retrofitting (for example when building a sunroom on to an existing deck) as the deck surface boards can be removed to install the piles and then reaffixed afterward. Because they don’t require curing time and, due to their status as an engineered products, fewer building inspections are required by municipal officials. This speedy and precise installation helps to keep projects moving along quickly, making steel piles a popular choice for both contractors and homeowners.

Bridges and culverts on steel piles and reinforced concrete sheet pile cofferdam General Provisions

1. Punched steel sheet pile (including reinforced concrete sheet piles, the same below) before the cofferdam deal piling equipment to conduct a comprehensive inspection.

2. Before lifting steel sheet pile, steel sheet pile site should be cleaned groove, locking should be trimmed or test plug; steel sheet pile group fight component should rugged gripper prison, spreader should not be tied to the steel sheet pile fixture. Welded steel sheet pile rings should someone check, if necessary trial hanging.

3. Hammers and hoist should set up special operations. Steel sheet pile lifting, should obey the command signal. When the job should be on leash rope slip sheet piles to prevent sharp swings after lifting. No piles of steel sheet pile lifted position near the front can not stop people in place.

4. When the steel sheet pile into the lock port, the result of resistance can not be inserted into the locking position and the need to hammer piles are pressed into the wire rope hoist should be used to control the whereabouts of the pile hammer stroke to prevent sudden decline pile hammer with steel sheet pile.

5. Punched steel sheet pile, as a result of insufficient height crane can be moved downward hanging position, hanging points but not less than 1/3 of the pile under pile length position.

6. When the steel sheet pile hammer sinking, the initial phase should be tapped. Pile cap (pad) should be replaced deformation.

DRIVEN STEEL PILING

A range of steel sections can be used for piles. The most common are tubes, universal columns (or H piles) and rectangular hollow sections. Driving piles, as opposed to drilling bores, can be advantageous because the soil displaced by driving the piles compresses the surrounding soil, resulting in greater friction against the sides of the piles, thus increasing their load-bearing capacity. In addition, as driving a pile displaces the soil rather than removes it, there is no cost of spoil disposal incurred. This can be particularly beneficial if the soil is contaminated.

A wide range of sizes of steel tube (or pipe) is commonly available and Piling Contractors have experience in driving tubes from 350 mm to 1500 mm diameter with wall thicknesses from 7 mm to 25 mm.

Tubular piles can be driven with either an open bottom end or closed end. When driven open end, soil is allowed to enter the bottom of the tube. If an empty pipe is required, an auger can be used to remove the soil inside following driving. If the soil is suitable internal cleaning could also be carried out by water jetting.

Closed end pipe piles have the bottom of the pile sealed with a steel plate or cast steel shoe. When driving through hard strata pile toes may be reinforced with a secondary driving shoe to assist penetration and minimise pile damage.

The structural capacity of tubular piles is primarily calculated based on steel strength and concrete strength (if filled). Corrosion can be dealt with by application of protective coatings, by allowing a sacrificial thickness of steel or by adopting a higher grade of steel than otherwise needed.

Steel tube piles can either be new steel manufactured specifically for the piling industry or reclaimed steel tubular casing previously used for other purposes such as oil and gas exploration. Most steel tube piles can readily be spliced to provide greater depth capability than a driving rig can accommodate.

H-Piles and Universal Columns (UC’s) are structural beams that are driven in the ground for deep foundation application. They can be easily cut off or joined by cutting and welding. If a steel pile is driven into a low pH soils or where water flows readily then there is a risk of corrosion, coal-tar epoxy or cathodic protection can be applied to slow or eliminate the corrosion process.

Sometimes a combination of steel tubes and steel piles are used to make a “combi wall” this benefits from the strength properties of tubular piles but at reduced materials cost.

Piling Contractors installs driven steel piles up to 1500mm diameter, up to 50m in single lengths and at rakes of up to 1 in 3.

The processes consist of pitching and driving in a fixed land based leader or free driving piles with rope suspended hammers. Use of fixed leaders allows greater control of position and verticality.

When working over water the same installation processes are used or piles can be driven through our rotating marine leader which can traverse in all directions on and grid arrangement and rotate 360 degrees to pick up any pile on rakes up to 1 in 3 within a defined grid arrangement.

STEEL PILES

The use of steel piles has increased significantly in residential and non-residential construction, especially where there are difficult ground conditions and structures are subjected to heavy concentrated loads.

Our versatile range of steel pile dimensions and products allow you to select the optimal size and length of pile for all soil conditions. Steel piles can be installed using light equipment, which conserves the environment and reduces excavation need and costs considerably.

Build stronger with high performance RRs and RDs steel piles

Our high-strength RRs and RDs piles, in combination with efficient designing, easy and quick installation, lower environmental impact than traditional piling create a solution that is now stronger than ever. By using the higher steel grade S550J2H, the pile’s load-bearing capacity can be added by 25% over that of steel grade S440J2H. The increased load-bearing capacity of the pile can be utilised by decreasing the number of piles. For the customer, this means a significant improvement in the overall economy of the project.

A huge cargo of steel piles has been unloaded in Dockyard as part of the South Basin project.

The piles will be drilled into the seabed to secure the reclaimed land that will form the foundations of the America’s Cup village.

The steelwork arrived in the West End last week on board the BBC Tennessee from Baltimore in the United States. Project managers expect to start driving the piles into the earth within the next couple of weeks.

Andrew Dias, the general manager of the West End Development Corporation, told The Royal Gazette that the project was “progressing well” and remained on time and on budget.

“The steel as well as the other infrastructure is now on site, although obviously not on the reclaimed land as the aggregate is still being spread out,” he said.

“We have taken delivery of 2.15 tonnes of steel piles, 1,726 sheet piles, 37 Y-shaped piles and 39 anchor piles.

“The steel work to create the perimeter is expected to take around eight weeks to complete, at which time a concrete cap will be added to the steel structure.”
