PHC pipe pile optimization and construction method suitable for high underground water level thick sand layer
The invention relates to a PHC pipe pile optimization and construction method suitable for a high underground water level thick sand layer. S1, preparation before construction is conducted, specifically, a construction site is confirmed, and the construction site is trimmed; s2, pouring and manufacturing a pipe pile, confirming a forming method, designing a punching position, confirming the size of a steel pipe, and preparing materials and pouring; s3, geological conditions are confirmed, and a construction method is selected; the PHC pipe pile optimization method has the advantages that finite element simulation software is used in an auxiliary mode to conduct pile sinking simulation on the PHC pipe pile, so that the position of a through hole is determined more conveniently and rapidly, the drop hammer impact force and the drop hammer frequency can be evaluated through a successfully-established finite element model, and therefore construction safety is guaranteed; underground water is extremely easily influenced by the environment and seasonal climate, the problem that after a pile foundation penetrates through underground confined water, water gushes along a pipe, and the pressure intensity of a closed space in a column is too large can be effectively solved, so that structural damage to the PHC pipe pile is avoided, and safe implementation of foundation engineering is guaranteed.
本发明涉及一种适用于高地下水位厚砂层的PHC管桩优化及施工方法，包括以下步骤；S1、施工前准备，确认施工场地，对施工场地进行修整；S2、浇筑制作管桩，确认成型方法，设计打孔位置，对钢管尺寸进行确认以及备料浇筑；S3、确认地质条件，选择施工方法；本发明PHC管桩优化特点就是辅助使用有限元模拟软件对PHC管桩进行沉桩模拟，从而更便捷、迅速的确定贯穿孔位置，还可以通过已经建立成功的有限元模型，对落锤冲击力和落锤次数进行一个评估，从而保证施工安全性；地下水极易受到环境和季节气候的影响，本发明能有效解决桩基穿过地下承压水后造成水沿管内喷涌使柱内封闭空间压强过大的问题，从而避免PHC管桩发生结构破坏，保障基础工程安全实施。
