Building pile foundation bottom sediment treatment and reinforcement construction method
The invention discloses a construction method for sediment treatment and reinforcement at the bottom of a building pile foundation, and relates to the technical field of building pile foundes.The construction method comprises the following steps that S1, holes are distributed and drilled, specifically, constant-speed stable drilling needs to be guaranteed during drilling, a monitoring device is arranged on a drilling machine, and a speed measuring system is arranged in the monitoring device and comprises an accelerometer; the accelerometer is mainly used for collecting acceleration signals of the drilling machine, judging whether reinforcing steel bars in the pile are encountered or not and whether a gravel pile body and sediment appear or not according to the acceleration characteristic signals, and calibrating and judging the position where a relative problem appears on the pile body; s2, high-pressure rotary jet hole washing is carried out; S3, water lifting deslagging and hole cleaning are carried out; S4, sediment treatment result inspection is carried out; S5, slurry is prepared, S6, high-pressure grouting is carried out, and S7, finally, core pulling reinspection and static pressure load test are carried out, and whether pile foundation sediment treatment and reinforcement are qualified or not is inspected. The construction method for sediment treatment and reinforcement at the bottom of the building pile foundation is good in sediment treatment effect and high in pile foundation strength.
本发明公开了建筑桩基础底部沉渣处理及补强施工方法，涉及建筑桩基技术领域，本发明包括以下步骤：S1：布孔及钻孔：钻进时应保证匀速平稳钻进，在钻机上设立监测装置，监测装置内设置有速度测量系统，速度测量系统包括加速度计，加速度计主要用于采集钻机的加速度信号，在根据加速度特征信号判断，判断是否遇到桩内钢筋、是否出现碎石桩身以及沉渣，并且标定判断桩身出现相对问题的位置；S2：适高压旋喷洗孔：S3：水举排渣清孔：S4：沉渣处理结果检验：S5：配制浆液：S6：高压注浆：S7：最后抽芯复检和静压荷载试验，检验桩基沉渣处理以及补强是否合格。本发明为建筑桩基础底部沉渣处理及补强施工方法，沉渣处理效果好，桩基强度高。
