Shield tunneling construction method based on instrument and inspection dual monitoring

The invention provides a shield tunneling construction method based on instrument and inspection dual monitoring. The shield tunneling construction method comprises the following operation steps that S1, a tunnel portal ring is designed, installed and accepted; s2, constructing a receiving base; s3, shield tunnel cut-through measurement is carried out; s4, breaking the tunnel portal; s5, shield monitoring is carried out; s6, the receiving section duct piece is reinforced; s7, shield tunneling of the receiving section; s8, tunneling a reinforcing area; s9, advancing an out-of-hole section; and S10, tunnel portal blocking is carried out. The construction organization design is scientific and reasonable, the monitoring effect is good, the safety is high, and the construction efficiency and the construction quality can be effectively improved. 本发明提供了一种基于仪器和巡视双监测的盾构出洞施工方法，包括以下操作步骤：S1、洞门环的设计、安装和验收；S2、施工接收基座；S3、盾构隧道贯通测量；S4、洞门破除；S5、盾构监测；S6、接收段管片加固；S7、接收段盾构掘进；S8、加固区掘进；S9、出洞段推进；S10、洞门封堵。本发明施工组织设计科学合理，监测效果好，安全性高，能有效提高施工
