FRP plate strip type foundation pit support structure and construction method
The invention discloses a FRP plate strip type foundation pit support structure and a construction method. The structure is mounted around a foundation pit for realizing the support of the foundation pit; the positioning paying-off is performed along the foundation pit support; pipe piles manufactured by FRP rib materials are inserted in leading holes; three pipe piles are formed to one set to form support pile bodies; hoop locks for holding the pipe piles and supporting the three pipe piles are respectively arranged at the tops of the pipe piles and in the positions of the pile piles at the dig depth bottom of the foundation pit; and FRP strip cloth is wound and connected among the pipe piles at the front sides of the support pile bodies. The FRP pipe piles are adopted, and the hoop locks are arranged to form transverse support and restraint for the support pile bodies, so that the support structure is more stable; the DRP strip cloth achieves a better soil stop effect, so that the type of the foundation pit support can be enriched, the selection range of the foundation pit support is widened, the construction period is shortened, and the energy conservation and the consumption reduction are realized; and the form of the foundation pit support can be expanded from a conventional plane mode to a space mode, so that the rigidity of the support structure is effectively improved, and the safety and the stability of foundation pit engineering are realized.
