摘要
煤矿采空区在山西省普遍存在,天然气管道若经过采空区,有塌陷危险,因此需要对这些区域进行地表变形监测和提前采取应对措施。以位于山西省大同市左云县境内的某输气管道工程为实例,介绍了采空区对输气管道的危害、地表变形监测和应对措施。针对不同沉陷病害采取了裂缝封堵和孔洞浆砌处理手段,防止了水分进入土体,取得了较好的应用效果。
Based on widely existed goaf in Shanxi Province,with collapse danger when gas pipeline crossing up from goaf,surface deformation monitoring and countermeasures in advance were needed.A gas transmission pipeline engineering of Zuoyun county of Datong city was taken as example,damage of gas pipeline,surface deformation monitoring and countermeasures were introduced.Fracture plugging and treatment of hole pulp were adopted based on different subsidence,preventing water from entering the soil,with good effect.
