长距离人工顶管施工安全控制技术研究

Research on Safety Control Technology for Long-distance Artificial Pipe Jacking Construction

传统人工顶管的施工工艺未考虑施工过程中气候的影响,特别是雨水丰沛区施工时,常出现降水量过大影响施工的情况,且管节吊装缺失特定的夹具,导致吊装转运不便、顶管时需要后背墙、工具管和顶镐机架等。文章结合益阳市金花湖路人工顶管施工现场,提出一种针对降雨丰沛区,减轻降雨影响的人工顶管施工方法,有效地保证了现场的施工安全。

The construction technology of traditional artificial pipe jacking does not consider the influence of climate in the construction process.Especially in the construction of rainfall-rich areas,excessive rainfall often affects the construction,the lack of specific fixtures for pipe section hoisting leads to inconvenience in hoisting and transportation,and back wall,tool pipe and jacking rack are needed when pipe jacking is conducted.Based on the artificial pipe jacking construction site of Jinhuahu Road in Yiyang City,this paper puts forward a kind of artificial pipe jacking construction method to reduce the influence of rainfall in the area with abundant rainfall,which effectively ensures the construction safety of the site.
