Abstract：
Natural gas, water supply and telecommunication pipelines on the drainage construction site of Qingta Project affect the design position of drainage pipeline and open excavation construction should not be adopted, so non-excavated tube drawing processes are adopted for drainage construction. Non-excavation technique sets, changes and repairs various underground pipelines through guiding and directional drilling methods with excavation of only a small ground area. This technique produces a little influence on ground surface and ensures favorable construction effects. However, this technique still has some limitations, such as defects in gravity flow drainage, etc., and shall be further improved in future drainage projects.
