Construction method of pore-forming pouring pile
The invention relates to a construction method of a pore-forming pouring pile of a prefabricated concrete remaining wall. The method includes the steps of making a steel combined protecting cylinder or a concrete combined protecting cylinder of a steel and concrete combined protecting cylinder serve as an advance supporting system of a pore-forming working section in a pile hole, and pushing the advance supporting system to move forwards through a detachable hydraulic system in the pile hole, wherein the advance supporting system is a temporary remaining wall protecting system used during pore-forming work of the pore-forming working section. Under the protection of the combined protecting cylinder, namely, the advance supporting system, prefabricated concrete pieces are spliced in a segmented mode according to work links so that a concrete supporting ring can be formed to serve as a hole wall concrete remaining wall protecting system of the pile hole, and the hole wall concrete remaining wall protecting system is a pile hole remaining wall protecting system used in the whole pile forming work. The problem that an existing dry-work pore-forming pouring pile is hard or impossible to form in a soft soil stratum, a quicksand stratum and a water bearing stratum is solved, the bearing capacity and pile body stability of the pore-forming pouring pile are greatly improved, and comprehensive economic and social benefits are remarkable.
