小导管注浆预支护技术在城市浅埋暗挖隧道的应用

The Application of Technology on Ductule Casting Paddle Timbering in Urban Shallow-cover and Close-cut Tunnel

结合深圳市向西北人行地道超前小导管注浆预支护的工程实践,介绍了小导管注浆预支护技术在城市浅埋隧道中的应用.

The technology on ductile casting paddle timbering is used to assistant construction's measure in common in close-cut constructing tunnel. It can availably improve self-steady ability, lowland seep water and cortrol settlement of stratum. According to engineering practice in ductile casting paddle super timbering of Xing Xibei pedestrian subway in ShenZhen, the successful application shallow-cover tunnel in city is introduced in this paper.
