软土地区水平定向钻施工对周围环境的影响

The effect of horizontal directional drilling in soft soil on the near environment during installing pipes

通过水平定向钻在市政工程中的广泛应用,水平定向钻施工越来越显示出它的优势,其施工对周围环境的影响需要评估。为此,对水平定向钻小直径管道施工过程引起的力学效应进行了讨论,重点探讨了拉力、扭矩和泥浆的影响,同时通过分析沉降位移监测值,就具体施工过程所带来的影响进行了讨论,得出了有益的结论。

Due to the application of horizontal directional drilling in municipal engineering, it has its own advantage over pipes installed, and much more attention should be paid to the effect on near environment during installing pipes with horizontal directional driUing. The construction mechanics effects of horizontal directional drilling are analyzed, for instance, the pulling force, moment of torsion and mud fluid. By analysis of settlement displacement, the actual effect during practical construction is analyzed, and useful conclusion is made.
