Prestressed pipe pile and preparation method
The embodiment of the invention discloses a prestressed pipe pile and a preparation method, the prestressed pipe pile comprises a pipe pile body and a steel plate groove, a vertical drainage groove is formed in the length direction of the pipe pile body, permeable meshes are formed in the steel plate groove, and the steel plate groove is fixedly clamped in the drainage groove to form a drainage cavity with the drainage groove; the wall thickness of the pipe pile body is increased by h compared with the wall thickness of a standard PHC pipe pile of the same model, the inner diameter of the pipe pile body 1 is d, and the depth of the drainage groove is equal to the increased thickness h. According to the scheme, the technical problems that in order to reduce the negative friction of a pipe pile hole, a hole is formed in a pile body of an existing pipe pile, the strength of the pipe pile is weakened, and the pipe pile is only suitable for a low-bearing-capacity composite foundation and not suitable for a high-bearing-capacity foundation are solved.
本申请实施例公开了一种预应力管桩及制备方法，所述预应力管桩包括管桩主体、钢板槽，沿着管桩主体的长度方向设置有竖直排水槽，所述钢板槽上设置有透水网孔，所述钢板槽固定卡接在所述排水槽中，以与所述排水槽形成排水空腔；所述管桩主体的壁厚比同型号标准PHC管桩壁厚增加厚度h，所述管桩主体1的内径为d，所述排水槽的深度与增加厚度h相等。本案解决了现有管桩为了减少管桩孔负摩阻力在桩身开孔而削弱了管桩的强度，只适用于低承载力的复合地基，而不适用于高承载力的地基的技术问题。
