More Information
Summary:The supporting system comprises a plurality of steel sheet piles, the steel sheet piles are arranged in a soil body at the position of the side wall of the pit in the pit in a driving mode and form a circle along the outline of the pit in the pit in a surrounding mode, and the adjacent steel sheet piles are connected through locking openings matched with the edges of the steel sheet piles. The top ends of part of the steel sheet piles are higher than the top ends of the steel sheet piles on the two sides, and pile bodies of the higher parts of the steel sheet piles are fixed to the reinforced concrete cast-in-place piles on the outer sides through tying steel wire ropes in a tying mode. The steel sheet pile and the reinforced concrete cast-in-place pile are tied and fixed through the tying steel wire rope, the construction space of the pit-in-pit is liberated, the construction efficiency is improved, meanwhile, a brick blank film is replaced by the inflation plate, the nylon film and the water-based lubricant
