摘要
Abstract
The top pipe method for tunnel construction is increasingly being applied in domestic municipal and water supply projects,with the characteristics of high safety and fast construction speed.With the continuous development and maturity of pipe jacking technology,a large number of ultra large caliber and ultra long distance pipe jacking projects have emerged.Combining with the subsequent optimization project of CYB7～CYB8 hard rock pipe jacking construction in the Hanjiang,Rongjiang,and Lianjiang water systems,this article adopts construction techniques such as circulation flushing and slag carrying,sediment treatment,mud drag reduction,and graded jacking through reasonable selection of jacking machines.It solves the common problems of sedimentation,slag return,and high resistance in long-distance hard rock pipe jacking,achieving smooth pipe jacking and summarizing corresponding construction techniques.关键词
