More Information
Summary:The construction method comprises the following construction steps of S1, double-layer steel pipe pile manufacturing, S2, steel pipe pile hole construction, S3, concrete pouring and steel pipe pile static pressure, S4, filling liquid injection of the double-layer steel pipe piles, S5, inter-pile waterproof curtain construction and S6, sleeve valve grouting joint treatment. S7, tool type surrounding purlins and recyclable anchor cables are installed, S8, foundation pit synchronous excavation is conducted, and S9, components and accessories are recycled. An outer pipe and an inner pipe of the double-layer steel pipe slope protection pile are connected through a reinforced body formed by welding a guniting pipe, water suction and a base plate, lubricating liquid is injected through high-pressure splitting of the guniting pipe before the double-layer steel pipe slope protection pile is pulled, the interface of the double-layer steel pipe pile and a concrete body around the pile is broken, and the pile pulling eff
