[0002] Anti-slip piles are a common form of deep foundation pit support. When the lateral pressure of the foundation pit soil is large, cast-in-place reinforced concrete pile slabs are often required between the anti-slip piles after the soil is excavated in layers. The most common pile slab construction technology is to excavate the foundation pit in layers after the anti-slip pile construction is completed and meets the strength requirements, drill holes and plant steel bars between the anti-slip piles, tie the steel bars, install the single-sided wooden formwork, and then reinforce it with wooden squares, steel pipes, etc., and then pour concrete. It is troublesome to reinforce the single-sided wooden formwork with steel pipes on the soil in the foundation pit. Reinforcement by inserting steel bars, steel pipes, etc. and anchoring them in the soil is prone to deformation and shaking, and is prone to accidents such as leakage and mold explosion. The pile slab construction efficiency is low, the construction quality is poor, and the safety risk is high.
