准神铁路石砭煤矿采空区路基注浆加固治理技术

Zhunshen Railway Shibian Coal Mining Goaf Roadbed Grouting Reinforcing Technology

根据工程地质条件和采空区稳定性评价,采用注浆技术对铁路路基采空区进行加固处理。通过物探及钻探确定采空区注浆治理范围,确定治理方案,并采取针对性措施,有效充填了采空区空洞,保证了路基的稳定性。

According to the engineering geological condition and evaluation of the stability of goaf,we used grouting technology to reinforce the goaf of railway roadbed.The goaf grouting range is determined through geophysical prospecting and drilling prospecting,the treatment scheme is also determined,and the targeted measures are taken,thus having effectively filled the goaf cavities and ensureed the stability of roadbed.
