浅谈水利工程顶管施工技术应用

Discussion on the Application of Pipe Jacking Construction Technology in Hydraulic Engineering

本文以某河道施工工程中某地涵施工为例,根据本工程地质、水文环境及现场施工条件,确定采用DN4000泥水平衡顶管掘进,它对土质范围适应性广,长距离顶进能有效地保持挖掘面的稳定,对掘进周围的土体扰动情况影响较小,具有满足顶管施工的质量和进度,减少周围环境影响的特点。

Taking the construction of a culvert in a river construction project as an example,based on the engineering geology,hydrological environment and on-site construction conditions,this paper determines to adopt dn4000 slurry balanced pipe jacking excavation,which has wide adaptability to the soil range.Long distance jacking can effectively maintain the stability of the excavation surface,and has little impact on the soil disturbance around the excavation.It has the characteristics of meeting the quality and progress of pipe jacking construction and reducing the impact on the surrounding environment.
