Directional drilling in sewage pipeline construction
In order to solve the problem of pipeline construction in limited space crowded with roads,,underpassing railways,highways rivers and other structure,where excavation is not allowed,the trenchless directional drilling technology is introduced for pipeline laying.The technology is not affected by the buried depth of the pipeline,the ground limit,the groundwater and so on,the construction speed of the proposed technology is fast,the efficiency is high,the comprehensive cost is low,and the technology can solve a series of problems that can not be solved by the excavation of the buried pipe skillfully,and fully demonstrates its superiority.Taking Yuanqingyuan sewage pipe laying in Guangming District of Shenzhen as the background,this paper briefly describes the construction principle,advantages and disadvantages of trenchless directional drilling technology,systematically summarizes its main processes,and analyzes the quality control under each operation process.
