Application of Pipe Traction and Burying Technology in Trenchless Directional Drilling in South to North Water Transfer Project

Abstract:

Jining city sewage interception diversion is an important project for south to north water transfer trunk in the east line, 5.9km pipelines should be laid from the Jining City sewage treatment plant first, then by the open-channel hydraulic system, to diverse reclaimed water into the water storage area to ensure no reclaimed water entering the trunk during south to north water transfer. The pipeline is constructed through the old canal and Guangfu River of southern Jining. Guangfu River is a flood channel, pipe traction and burying technology in trenchless directional drilling was used without affecting the original function of the channel. Combined with the engineering example, this paper introduces the pipe traction construction technology in trenchless directional drilling.
