摘要
千岛湖配水工程分水江左右岸地下检修阀室断面为窄高的城门洞形,且纵向长度较短,没有条件布置额外的施工支洞分层开挖。本文介绍的开挖施工方案,有效解决了现场问题,安全、高质量地完成了检修阀室的开挖支护,节约了直线工期。
The underground service valve chest cross section on the left and right bank of Fenshui River in Qiandaohu Water Distribution Project is narrow and high city-gate rorm. Its longitudinal length is shorter. There are no conditions to arrange additional construction branch holes for stratified excavation. The construction excavation plan introduced in the paper can effectively solve the problems in the site. Excavation support of service valve chests can be finished safely with high quality, thereby saving straight line construction duration.
