Construction method of anti-floating anchor rod under working conditions of high water level and large permeability coefficient
The invention belongs to the technical field of foundation engineering, and discloses an anti-floating anchor rod construction method under the working conditions of high water level and large permeability coefficient. S1, measuring distribution points; s2, drilling a mounting hole; s31, drilling a first test hole: enabling the environment and the structural size of the first test hole to be the same as those of the mounting hole; s32, mixing the cement paste and the accelerator according to the trial proportion to obtain a mixed solution; s33, injecting a mixed solution into the first test hole, and recording initial setting time; s34, measuring the water absorption rate of the first test hole to the mixed solution; s35, according to the initial setting time of the mixed solution and the water absorption rate of the first test hole, the trial preparation proportion is adjusted, the steps S31-S34 are repeated until the initial setting time of the mixed solution reaches the target initial setting time, meanwhile, the water absorption rate of the first test hole to the mixed solution reaches the target water absorption rate, and at the moment, the trial preparation proportion is the standard operation proportion; s36, cement paste and an accelerator are prepared according to the standard operation proportion, and grouting liquid is obtained; s4, anchor rods are installed; s5, grouting liquid is poured into the mounting holes; and S6, maintaining.
本发明属于地基工程技术领域，公开了一种高水位大渗透系数工况下抗浮锚杆施工方法。S1、测量布点；S2、钻安装孔；S31、钻第一测试孔：使第一测试孔的所处环境及结构尺寸与安装孔相同；S32、按照试配比例混合水泥浆和速凝剂，获得混合液；S33、向第一测试孔内注混合液，记录初凝时间；S34、测定第一测试孔对于混合液的吸水率；S35、根据混合液的初凝时间和第一测试孔的吸水率调节试配比例，重复步骤S31‑S34，直至使混合液的初凝时间达到目标初凝时间，同时使第一测试孔对混合液的吸水率达到目标吸水率，此时，试配比例即为标准作业配比；S36、以标准作业配比配置水泥浆及速凝剂，获得注浆液；S4、安装锚杆；S5、向安装孔内灌注注浆液；S6、养护。
