摘要
以实际工程为例,根据塌方情况决定了压力管道古河床段塌方处理方案,采用浇筑C20混凝土封闭、超前大管棚、灌浆、钢拱架支护跟进等方法快速通过塌方段,以做好塌方处理和支护工作。
Taking the practical engineering as an example,according to the collapse situation,the collapse treatment plan of the ancient riverbed section of the pressure pipeline was determined.C20 concrete casting,advanced large pipe shed,grouting,steel arch support and other methods were adopted to quickly pass through the collapse section to complete the collapse treatment and support work.
