水平定向钻技术在排水管道中的应用

Application of horizontal directional drilling technology in the drainage pipe.

随着城市化的发展，市政基础设施建设日益完善，水平定向钻逐渐被广泛应用于市政排水管道中。以江门市荷塘镇生活污水处理厂二期截污管网工程为例，由于本工程不具被明开挖施工条件，敷设的污水管道全部采用水平定向钻牵引施工，针对本工程的特点，对牵引管和沉井施工技术进行了详细介绍。

With the development of the city, the increasingly perfect of municipal infrastructure construction, horizontal directional drilling has been widely used in the municipal drainage pipeline. Taking the two phase sewage pipe network project of Jiangmen Hetang town sewage treatment plant as an example. Since the project is not being open excavation construction conditions, the laying sewage pipe is completely adopted by horizontal directional drilling traction construction. According to the characteristics of the project, it is introduced in detail that horizontal directional drilling and open caisson.
