WebThe installation sequence is determined by ground conditions but is normally on a 'hit and miss' 2 or 3 piles basis. After a sufficient initial curing period (2-4 days) and once each alternate pile is formed, the reinforced ‘male’ piles are installed. Pile overlap (cut) typically ranges from 75mm to 100mm. WebInstall pile cage reinforcement to allow the pile to carry the bending forces. 3. Allow concrete to gain its design strength. 4. Install a capping beam to tie piles together; ensuring the wall acts as a monolithic structure. 5. Commence reduced level dig to formation level. 6. Install temporary and/or permanent propping where design requires.
WebThe main advantages of secant pile walls are: 1. Increased construction alignment flexibility. 2. Increased secant pile wall stiffness compared to sheet piles. 3. Can be installed in … WebOne should consider “combined walls” when dealing with section moduli values greater than 3000 cm 3 /m as they will often represent a more economical and structurally superior retaining wall solution over the commonly used Z-sheet pile contiguous wall.
