塔什店风井冻结法施工壁后注浆技术方案

Scheme of grouting technology Tashidian shaft freezing wall

以塔什店风井冻结法施工为例,介绍了壁后注浆时机及注浆孔布置方式,阐述了注浆材料的选取要求,并说明了注浆施工工艺流程,提出了注浆安全管理及应急处理措施,保障了井筒壁后注浆的顺利实施。

Taking the freezing method of Tashidian shaft freezing walls as the example,the paper illustrates the selection requirements of the grouting materials,introduces the allocation methods for the backfill grouting time and grouting machine,indicates its construction craft procedure,and points out the grouting safety management and emergency treatment measures,so as to ensure the smooth operation of the backfill grouting.
