Construction method for vertical diaphragm wall of steep slope rockfill site
The invention provides a construction method for a vertical diaphragm wall of a steep slope rock-filled site. The construction method comprises the following steps: S1, geological investigation; different construction processes are set according to different geological environments; s2, building a platform; a wedge-shaped working platform is built; s3, a road is built, specifically, the construction road is built according to the terrain and the anti-seepage wall building position; s4, high-pressure jet grouting pile construction; s5, curtain grouting; and S6, grouting is terminated. By means of the combined technology of shallow rotary spraying and lower grouting, diaphragm wall construction under the complex geological condition is achieved, the problem that a stirring pile is not suitable for the site is solved, and the problem that in the grooving process, grooving is difficult due to hole collapse, slurry leakage and the like is solved.
本发明提供了一种陡坡填石场地垂直防渗墙施工方法，包括以下步骤：S1、地质考察；根据不同地质环境设定不同的施工工艺；S2、修建平台；建造楔形作业平台；S3、修建道路，根据地形及防渗墙建设位置修建施工道路；S4、高压旋喷桩施工；S5、帷幕灌浆；S6、灌浆终止。本发明通过浅部旋喷、下部灌浆的组合工艺，实现了复杂地质条件下的防渗墙建设，既规避了搅拌桩在该类场地不适用的问题，也避免了成槽过程中因塌孔、浆液漏失等导致的成槽困难等问。
