Construction method for post-grouting solidified mud cake on pile side of cast-in-place pile
The invention relates to the technical field of cast-in-place piles, and discloses a cast-in-place pile side post-grouting solidified mud cake construction method which comprises the following construction steps that (1) after cast-in-place piles are formed in a cast-in-place mode, the cast-in-place piles are internally provided with reinforcement cages, and pile side soil layers are arranged on the peripheries of the cast-in-place piles; a plurality of annular grouting pipes are arranged on the reinforcement cage, the annular grouting pipes are arranged at intervals in the axial direction of the reinforcement cage, and a plurality of peripheral grouting openings are formed in the annular grouting pipes; each annular grouting pipe is connected with a vertical grouting pipe, and a grouting opening is formed in the top of each vertical grouting pipe. Within 7-8 hours after the cast-in-place pile is cast and formed, unplugging is conducted on the multiple vertical grouting pipes and the multiple annular grouting pipes; and (2) after the cast-in-place pile is cast and formed for 48 hours, grout is sequentially cast into the multiple annular grouting pipes through the vertical grouting pipes in the direction from top to bottom, the grout enters the position between the periphery of the cast-in-place pile and the soil body on the pile side and is mixed with the mud cake on the periphery of the cast-in-place pile, and after the grout is hardened, the mud cake on the periphery of the cast-in-place pile is solidified.
本发明涉及灌注桩的技术领域，公开了灌注桩桩侧后注浆固化泥皮施工方法，包括以下施工步骤：1)、灌注桩灌注成型后，灌注桩中具有钢筋笼，灌注桩的外周具有桩侧土层；钢筋笼上设有多个环形注浆管，多个环形注浆管沿着钢筋笼的轴向间隔布置，环形注浆管上具有多个外周注浆口；各个环形注浆管分别连接有竖向注浆管，竖向注浆管的顶部形成有注浆口；灌注桩灌注成型后7‑8小时内，对多个竖向注浆管以及多个环形注浆管进行开塞；2)、灌注桩灌注成型48小时后，沿着自上而下的方向，通过竖向注浆管对多个环形注浆管依序灌注浆液，浆液进入灌注桩的外周与桩侧土体之间，与灌注桩外周的泥皮混合，待浆液硬化后，将灌注桩外周的泥皮固化。
