Problems solved by technology

However, after careful analysis, this scheme also has a fly in the ointment. The fasteners are connected by mutual insertion, which requires the pile body to accurately locate the position between each fastener when connecting each other. The connection between the two piles can only be realized when the positions are in one-to-one correspondence. Therefore, the docking process takes a long time to realize

Abstract

The invention belongs to the technical field of preformed units in the building industry and relates to a precast pile with a concave clamping platform and a convex clamping platform. The precast pile solves the technical problems that in the prior art, connection is not convenient and not firm. The precast pile comprises a pile body. The pile body is internally provided with a reinforcement cage. The reinforcement cage comprises a plurality of longitudinal reinforcement bars and spiral reinforcement bars fixedly connected with the longitudinal reinforcement bars. The two ends of the pile body are provided with a concave-convex clamping platform mechanism. When two adjacent pile bodies get close to each other, the concave-convex clamping platform mechanism can enable the two pile bodies to be matched in a clamped and connected manner so that the two pile bodies can be connected. According to the precast pile, the pile bodies can be quickly and firmly connected.

Description

technical field [0001] The invention belongs to the technical field of prefabricated parts in the construction industry, and relates to a prefabricated pile, in particular to a prefabricated pile with a concave-convex clamping platform. Background technique [0002] Due to the relatively poor quality stability of immersed tube piles, prefabricated prestressed concrete piles have developed rapidly in recent years. In the piling process, piles of different lengths should be selected according to different needs, which requires the piles to be connected to each other to form a longer pile body. [0003] The existing piles are connected by setting metal end plates at both ends of the piles. When two piles need to be connected, they are connected by welding the end plates of the two piles. The welding work is time-consuming and laborious, and the connection is inconvenient , In addition, the weld is easily corroded by the chloride salt in the soil, resulting in damage to the fas...
