地下地道施工注浆堵漏技术探析

On grouting and leakage-preventing technology of the underpass construction

针对火力发电厂中输煤地道施工完毕后存在的渗漏问题,分析了输煤地道注浆堵漏施工技术,通过压力注浆施工工艺,将聚氨酯化学灌浆料注入有渗漏部位的施工缝中,解决了建筑工程中构筑物施工缝的渗漏问题。

Aiming at the existing leakage problems after the construction of the coal handing underpass in the power plant, the author analyzes the grouting and leakage-preventing construction technology of the coal handing underpass, according to the stress grouting construction technology, makes the polyurethane chemical grouting material into the construction crack of having leakage part, and solves the leakage problem of the structure construction crack in the building project.
