地下综合管廊桥架小空间后成孔施工技术

The Construction Technology of Underground Integrated Pipe Gallery Bridge with Small Space

为尽可能地压缩地下综合管廊桥架生产加工时间,缩短桥架安装工期,节约施工成本,项目创新桥架小空间后成孔施工技术,解决了因分支桥架(软管)位置不易控制,从而导致供货周期延长和桥架安装时间延长的问题。

In order to compress the production and processing time of the underground comprehensive pipe gallery bridge as far as possible, shorten the installation period of the bridge and save construction cost, the project innovates the post hole construction technology of the bridge with small space, and solves the problem of extending the supply cycle and the installation time of the bridge due to the difficulty in controlling the position of the branch bridge(hose).
