摘　　要：中航支线顶管法电缆隧道接收井位于繁华市区,周围建筑物密集,路面交通繁忙,顶管接收段局部从电网营业厅大楼下部穿越,顶管接收成为顶管施工中的重大风险点。为此在顶管掘进到达前进行导线贯通测量,使顶管机始终以良好的姿态按预定方案贯入接收井预留洞口。接收端洞口加固、破除顶进范围内的竖井围护桩,采用填砂体封闭接收井,使顶管在填砂体内接收,确保了顶管接收安全。The pipe jacking receiving well of Zhonghang branch cable tunnel is located in a prosperous urban area, where there are many buildings and heavy traffic on the road. Part of the pipe jacking receiving section passes through under the power grid business hall building, so pipe jacking receiving is one of the major risks in the pipe jacking construction. Therefore, conductor penetration was measured before pipe jacking arrives, to keep the pipe jacking machine under good condition and entering the reserved hole of the receiving well according to the designed plan. The receiving end was strengthened and the retaining piles in the shaft around the jacking scope were removed. The receiving well was sealed by filling sand, so that the pipe jacking is received in the filling sand to ensure the safety of pipe jacking receiving.
