Prefabricated square pile and construction process thereof
The invention relates to a prefabricated square pile. The prefabricated square pile comprises a prefabricated pile body, wherein the prefabricated pile body comprises a pile tip and a plurality of branch piles, the adjacent branch piles are connected with each other, grouting holes are formed in the branch piles, the grouting holes in the adjacent branch piles communicate with each other, the pile tip is arranged on the branch pile located at the end part, a first flow dividing hole which is obliquely arranged is formed in the pile tip, one end of the first flow dividing hole communicates with the grouting holes, and the other end of the first flow dividing hole communicates with the side wall of the pile tip. According to the prefabricated square pile, the compactness of pile end soil of the prefabricated pile body can be enhanced, the bearing capacity of the end part is increased, and then the bearing capacity of the prefabricated pile body is increased.
本申请涉及一种预制方桩，包括预制桩本体，所述预制桩本体包括桩尖和若干个分桩，相邻分桩之间相互连接，分桩上设有注浆孔，相邻分桩上的注浆孔连通，桩尖设置在处于端部的分桩上，桩尖上设有倾斜设置的第一分流孔，第一分流孔的一端与注浆孔连通，另一端与桩尖侧壁连通。本申请能够增强预制桩本体桩端土的密实性，增加了端部承载力，继而增大预制桩本体承载力。
