管道施工工艺比选及实施效果评价

Pipeline Construction Process Comparison and Selection and the Implementation Effect Evaluation

德州经济技术开发区雨污分流项目现场工况条件复杂,地下障碍较多,通过对开槽施工、顶管施工进行比选,最终选定以路口分段施工、人工探挖、开槽布管为主,遇到热力管道、污水管道倒虹避让及人工掏挖布管的实施总方案,并制定规范操作流程,通过对实施效果跟踪评价,该方法较好地解决了现场实际困难,达到了预期目的。

The working conditions of the Rain and Pollution Diversion Project in Dezhou Economic and Technological Development Zone are complex and there are many underground obstacles. By comparing the advantages and disadvantages of slotting construction and pipe lifting construction, the final selection of intersection section construction, manual digging, slotting and pipe laying is given priority to.When encountering heat pipe and sewage pipe inverted rainbow avoidance, manual digging and pipe laying implementation of the general scheme, and the standardized operation process is formulated. Through the tracking and evaluation of the implementation effect, the method solves the practical difficulties and achieves the expected purpose.
