To solve the problems of pipeline construction in dense building spacing, difficult road occupation, under crossing railways, highways, rivers and other areas where excavation is not allowed, trenchless directional drilling technology is introduced for pipeline laying. This technology is not affected by the buried depth of pipelines, ground restrictions, groundwater, etc., and has the advantages of high construction speed, high efficiency and low comprehensive cost. It can skillfully solve a series of problems that cannot be solved by excavating buried pipelines and fully demonstrate its superiority. Based on the sewage pipeline laying in Guangming District, Shenzhen, this paper briefly expounds the construction principle, advantages and disadvantages of trenchless directional drilling technology, systematically sums up its main processes, and analyzes the quality control under each operation process.
