Analysis on Construction Control Measures of Small-diameter Long-distance Pipe-jacking
Small diameter steel pipe jacking is widely used in the construction of water supply and gas pipelines because of its flexibility to pass through some obstacles,environmental friendliness,high construction efficiency and low comprehensive cost.However,there are still some problems such as large jacking force,difficulty in measuring and correcting deviation,small internal working space and low construction efficiency.Based on the regional water supply guarantee project in the northern part of Shaoxing City,the construction difficulties of DN1 600 steel pipe jacking across the Cao'e River twice under complex working conditions are analyzed.The construction control measures suitable for small diameter long distance steel pipe jacking are put forward.
