Waarom damwanden gebruiken?

De meeste gebieden op het terrein zijn niet bijzonder gevoelig voor het verlagen van het grondwaterpeil. De opgraving in deze gebieden

zal worden behouden met horizontale houten palen die tussen stalen palen zijn ondergebracht (aangeduid als koningsposten).

De grond tussen de beiaard en de Tasman Gardens Apartments is gevoelig voor vestiging door grondverlies

waterdruk, dus in dit gebied zullen damwanden worden gebruikt. In elkaar grijpende staalplaten (damwanden) vormen een barrière tegen grondwaterverlies. De damwanden worden voorafgaand aan het uitgraven geïnstalleerd voor de bouw van de onderdoorgang.

Why use sheet piles?

Most areas on site are not particularly sensitive to lowering ground water levels. The excavation in these areas

will be retained with horizontal timber poles lodged between steel posts (referred to as king posts).

The ground between the Carillon and the Tasman Gardens Apartments is sensitive to settlement through loss of ground

water pressure, so in this area sheet piles will be used. Interlocking steel sheets (sheet piles) form a barrier to ground water loss. The sheet piles will be installed prior to excavation for construction of the underpass.

Working around the sewer

The sheet wall will be 40m long before it reaches the Tory Street Interceptor Sewer.

  • The sheet wall will be 40m long before it reaches the Tory Street
    Interceptor Sewer.
  • The sewer is an egg-shaped brick structure which is more than
    100 years old and is 8m below ground.
  • Monitoring equipment will be installed in the sewer manhole to
    measure any effects on the sewer.

What is sheet pile?

The term sheet pile refers to any retaining wall type that is a) installed into the ground by driving or pushing, rather than pouring or injection, and b) is of relatively thin cross-section and low weight so that the weight of the wall does not assist in the wall’s stability.

The modern sheet pile industry is a little more than 100 years old with perhaps the most important changes in type and selection of products occurring since the early 1970’s. Sheet pile have been used in a wide variety of applications, especially marine bulkheads and retaining walls where space is limited. In addition to these, a special type of retaining wall is the cellular cofferdam, which are used extensively for both temporary and permanent structures.

Sheet pile are made in a number of materials. The material chosen depends upon a number of factors including both strength and environmental requirements. The designer must consider the possibility of material deterioration and its effect on the structural integrity of the system. Most permanent structures are constructed of steel or concrete. Concrete is capable of providing a long service life under normal circumstances but has relatively high initial costs when compared to steel sheet piling. They are more difficult to install than steel piling. Long-term field observations indicate that steel sheet piling provides a long service life when properly designed. Permanent installations should allow for subsequent installation of cathodic protection before excessive corrosion occurs.

Nuovo composto Palancole in Acciaio per opere di ritenzione della terra

Questo articolo descrive un nuovo tipo di Palancole in Acciaio che viene applicato a opere temporanee di conservazione della terra per la costruzione di strutture sotterranee. Il sistema Palancole in Acciaio, il cosiddetto cappello Hat + H, ha una maggiore rigidità, un peso più leggero come una parete e può essere guidato più facilmente rispetto ai tradizionali muri di sostegno. La sezione che consiste in Palancola a forma di cappello e forma ad H è composta da una semplice saldatura di filetti. Il Palancola di 900 mm è il monopile laminato a caldo più largo al mondo, quindi il numero di pile può essere ridotto rispetto a pile convenzionali con larghezza di 400 mm. La forma ad H offre un’elevata rigidità come sezione composita.

Pertanto, le pile Hat + H possono raggiungere una costruzione rapida e un’elevata stabilità dei muri di contenimento e delle loro opere, ovvero rappresentano una soluzione per migliorare la sicurezza e la produttività, necessaria negli ultimi anni perché le strutture sotterranee sono diventate più complicate e più profonde con l’espansione urbanizzazione. Questo documento presenta i risultati di un test strutturale e test di guida su pile Hat + H su vasta scala al fine di verificare le prestazioni richieste come membro di muri di sostegno temporanei.

I risultati del test di flessione dimostrano che la pila Hat + H ha un’elevata capacità di flessione e può essere valutata come una sezione composita nella progettazione. Nel test di guida, il cumulo Hat + H era precedentemente fabbricato nel cortile e ripetutamente installato e estratto per simulare una situazione di uso temporaneo. Di conseguenza, è stato verificato che le pile Hat + H hanno un’elevata robustezza e guidabilità e sono membri appropriati per i muri di contenimento temporanei della terra.

Novel compound steel sheet pile for earth retaining works

This paper describes a new type of steel sheet pile that is applied to temporary earth retaining works for the construction of underground structures. The steel sheet pile system, so-called Hat+H pile, has higher rigidity, lighter weight as a wall and can be driven easier compared with conventional retaining walls. The section which consists of Hat-type sheet pile and H-shape are compounded by simple fillet welding. The sheet pile of 900 mm is the widest hot-rolled monopile in the world, so the number of piles can be reduced compared with conventional piles whose width is 400 mm. The H-shape provides high rigidity as a composite section.

Therefore, Hat+H piles can attain rapid construction and high stability of retaining walls and their works, that is, they are a solution for enhancing safety and productivity, which is required in recent years because underground structures have become more complicated and deeper with expanding urbanisation. This paper presents the results of a structural test and driving test on full-scale Hat+H piles in order to verify the required performance as a member of temporary retaining walls.

The results of the flexural test show that the Hat+H pile has high flexural capacity and can be evaluated as a composite section in design. In the driving test, Hat+H pile was previously fabricated in the yard and repeatedly installed and pulled out to simulate a situation of temporary use. As a result, it was verified that Hat+H piles have high robustness and drivability, and are appropriate members for temporary earth retaining walls.
