Steel sleeve for protecting pipe pile, preparation method of steel sleeve and pile sinking method
The invention discloses a steel sleeve for protecting a pipe pile and a preparation method and a pile sinking method of the steel sleeve, and relates to the technical field of soft soil foundation engineering.The steel sleeve for protecting the pipe pile comprises a steel sleeve body; a containing space is formed in the steel sleeve body and used for containing a pipe pile. The inner wall and the outer wall of the steel sleeve body are coated with polytetrafluoroethylene composite coatings; the raw materials of the polytetrafluoroethylene composite coating comprise polytetrafluoroethylene, carbon fibers and poly (p-hydroxyformate). The invention provides a steel sleeve for protecting a pipe pile, a preparation method of the steel sleeve and a pile sinking method, which are used for solving the technical problems that the friction force between an existing common steel sleeve and a soil body is relatively large, the steel sleeve is difficult to be driven into the ground, and the construction efficiency of pile sinking is relatively low.
本发明公开了一种用于保护管桩的钢套管及其制备方法、沉桩方法，涉及软土地基工程技术领域，其中，一种用于保护管桩的钢套管，包括：钢套管管体；所述钢套管管体内设有容纳空间，所述容纳空间用于放置管桩；所述钢套管管体的内外壁均涂覆有聚四氟乙烯复合涂层；所述聚四氟乙烯复合涂层的原料包括聚四氟乙烯、碳纤维和聚对羟基甲酸酯。本发明提供了一种用于保护管桩的钢套管及其制备方法、沉桩方法，用于解决现有的普通钢套管和土体之间的摩擦力较大，难以将钢套管打入地下，导致沉桩的施工效率较低的技术问题。
