Grouting system and technology suitable for high slope curtain grouting stability control
The invention discloses a grouting system and technology suitable for high slope curtain grouting stability control. According to the technical scheme, the grouting system comprises a pumping well, an inspection hole, a plurality of curtain grouting holes formed in a curtain grouting area and a grouting pipe, wherein the pumping well is arranged on the outer side of a curtain, and a pumping device is arranged in the pumping well; the inspection hole is formed in the inner side of the curtain, a plurality of soil pressure gauges are arranged on the hole wall of the inspection hole at intervals, and the soil pressure gauges are connected with an alarm device; and the grouting pipe is used for grouting into the curtain grouting holes and the inspection hole. According to the grouting system and technology suitable for high slope curtain grouting stability control, through the dual mechanism of induced grouting and pressure gauge response value monitoring, the slope stability during grouting is ensured while the anti-dispersion performance of grout flowing water is improved.
本发明公开了一种适用于高边坡帷幕注浆稳定性控制的注浆系统及工艺，其技术方案为：包括抽水井、检查孔、若干设于帷幕注浆区的帷幕注浆孔、注浆管，抽水井设于帷幕外侧，抽水井中设置抽水装置；检查孔设于帷幕内侧，检查孔的孔壁间隔设置多个土压力计，所述土压力计连接报警装置；注浆管用于向帷幕注浆孔、检查孔中注浆。本发明通过“诱导注浆+压力计响应值监测”的双重机制，在提升浆液动水抗分散性的同时确保注浆时的边坡稳定性。
