摘要
泥水盾构接收中常因加固缺陷造成人工破除围护桩时发生涌水涌砂。以沈阳地铁9号线曹仲站泥水盾构接收施工为例,通过研发出活塞式封闭接收钢环,利用钢板桩和在钢环内回填砂土,实现了左右线泥水盾构安全接收。
Water and sand gushing often occurs in artificial breaking pile of slurry shields. Based on engineering practice of Shenyang Subway Line 9,piston sealing steel ring was developed which used steel plate pile and backfill sand in steel ring to make the slurry shield receiving safe.
