铁路路基经过的地段常遇到地质溶洞和上世纪遗留的工业采空区,由于在实际施工中地下情况的不确定性,工程部门一般采用钻孔后压浆灌注施工工艺进行处理。钻孔后压浆灌注法也是一种最经济、最简单、最常用的一种方法。下面结合具体工程实例谈谈注浆法处理采空区的施工技术及注意事项。 Due to the uncertainty of the underground conditions in the actual construction, the engineering department generally adopts the post-drilling grouting and grouting construction process to deal with the geological caverns and the industrial goaf left over in the last century. Drilling after grouting perfusion method is also one of the most economical, easiest and most commonly used method. The following combination of specific engineering examples talk about the grouting method to deal with the construction of mined-out area and precautions.
