1. a kind of installation method of prefabricated T-type sheet pile foundation pit enclosure structure, characterized in that the following steps are included:

  • (1) self-solidifying stream of constructing on fender post position moulds the soil bodyIt forms comb teeth-shaped self-solidifying stream and moulds soil mass section, Soil-cement body is formed using whirl spraying, stirring or boring method, solidified earth is stirredMix body, cement mortar body or self-solidifying slurry body;

    (2) it assembles and is implanted into or is pressed into T-type sheet pileT-type sheet pile is hung to slot section, is beaten by self weight or high-frequency vibration, resistance is overcome to be implanted to the self-solidifying stream modeling soil having becomeIn body, T-type sheet pile is spliced by horizontal joint and vertical connector, continues to repeat to hang splicing after splicing to certainly pre- calibrationIt is high;

    The horizontal joint of T-type sheet pile fills high-strength resin material on joint surface;

    T-type sheet pile is using self weight insertion, piling machine or vibration hammer insertion;

    T-type sheet pile is longitudinal spliced and connect with crown beam;

    The T-type sheet pile is the prefabricated standard component of modularization;

    Company between standard componentIt is equipped with modular connection;

    Connector includes horizontal joint and vertical connector;

    Horizontal joint is screw lock formula mechanical connection, and vertical connector isThe tongue and groove joggle of embedded article rubber water stop;

    (3) installation or cast-in-situ steel reinforced concrete crown beamAfter the solidification of the self-solidifying stream plastomer in T-type sheet pile stake week, T-type sheet pile top solidified earth is removed, is installed by stake top connecting screw holeThen anchor bar is connect or is anchored into cast-in-place concrete crown beam with prefabricated crown beam;

    T-type sheet pile is embedded with connecting screw hole on top, convenient for connecting and being anchored into crown beam with crown beam reinforcing bar.
