Method for rectifying deviation of inclined pipe pile
The invention relates to a method for rectifying the deviation of an inclined pipe pile. The method includes the following steps that S1, a doubtful foundation pile is determined; S2, pile body integrity detection, horizontal displacement and inclination angle measurement are carried out; S3, whether data in the second step are qualified or not is judged, namely, if qualified, a top pushing methodis adopted to correct the deviation, and if not, a cast-in-situ bored pile is adopted to fill the pile; S4, after deviation rectification is completed by the top pushing method in the third step, crack reinforcement is then conducted; and S5, after crack reinforcement is completed, pile body integrity and bearing capacity are tested, if the test is unqualified, the cast-in-situ bored pile is adopted to fill the pile, and if the test is qualified, the work is completed. According to the method for rectifying the deviation of the inclined pipe pile, the inclination and fracture positions of theinclined pipe pile are evaluated in a targeted manner, the pushing pressures is selected reasonably, the inclined pipe pile can be effectively protected from damage, the reuse of the inclined pipe pile can be realized, the number of piles to be filled is reduced, the treatment cost is reduced, and the method has good economic value.
本发明涉及一种处理倾斜管桩的纠偏方法，包括如下步骤：S1：确定疑问基桩；S2：桩身完整性检测、水平位移及倾斜角测量；S3：判断S2数据是否合格，即合格采用推顶法纠偏，不合格采用钻孔灌注桩进行补桩；S4：在S3完成推顶法纠偏后，再进行裂缝加固；S5：裂缝加固完成后，进行桩身完整性及承载力检测，若检测不合格则采用钻孔灌注桩进行补桩，若合格则完成工作。该处理倾斜管桩的纠偏方法有针对性的对倾斜管桩倾斜及断裂位置进行评估，合理的选取推顶压力，能有效的保护倾斜管桩不受破坏，可以实现对倾斜管桩的再利用，减少补桩数量，减低处理成本，有较好的经济价值。
