Construction method for recycling existing and old pile foundation
The invention discloses a construction method for reusing an existing and old pile foundation, and relates to the technical field of construction. Comprising the following steps that S10, an old pile head is excavated and found in a construction site; s20, in the found old pile heads, the old PHC piles and the old cast-in-place piles are detected, and appearance detection, SIT integrity testing, DLT dynamic load testing, CCTV inspection and static load testing are conducted on the old PHC piles; pile body core drilling detection and pile bottom rock core drilling detection are conducted on the old cast-in-place pile; and S30, according to the detected result whether the old piles are effective or not, the positions, the sizes and the number of the new piles are determined according to the project construction requirements so as to meet the project requirements. According to the method, the old PHC piles and the old cast-in-place piles are detected, the qualified old piles are reused, the cost is saved, the construction period is shortened, the old piles are not removed, secondary disturbance to underground soil is avoided, and meanwhile other influences caused by the fact that new piles are too dense are avoided.
本发明公开了一种现存旧有桩基础再利用的施工方法，涉及施工技术领域；包括以下步骤：S10.在施工场地开挖寻找旧桩桩头；S20.在寻找到的旧桩桩头中，分别对旧PHC桩和旧灌注桩进行检测，其中，旧PHC桩进行外观检测、SIT完整性测试、DLT动力荷载试验、CCTV检查和静力荷载试验；旧灌注桩进行桩身钻芯检测以及桩底岩钻芯检测；S30.根据检测的旧桩是否有效结果，再根据项目施工需求确定新桩位置、尺寸及数量，以满足项目所需。本发明通过对旧PHC桩和旧灌注桩进行检测并对合格的旧桩重利用，节约成本且降低了工期，并且不清除旧桩避免了对地下土体的第二次扰动，同时亦不会因新桩过密而造成其他影响。
