市政污水管道的铺设一般采用的是管沟开挖铺设,这种方法不仅操作简单,而且造价经济,但如果遇到地下水位较高和管道周边存在既有建筑的情况,则采取工艺相对复杂的顶管技术施工更具有优势。论述了工程和地质情况,根据工程实际情况提出了两种施工方案。采用开挖施工和泥水平衡顶管施工两种施工方案,通过对两种施工方案进行比较,决定采取顶管方法进行污水管线施工。详细地列举了泥水平衡顶管施工方法的优点,采用这种方法后,取得了良好的经济效益。
The construction of municipal sewers is usually carried out by trench ditching. This method is not only simple to operate but also cost-effective. However, if it encounters high groundwater level and existing buildings around the pipeline, the process is relatively complicated Pipe jacking construction has more advantages. Discussed the engineering and geological conditions, according to the actual situation of the project proposed two kinds of construction programs. Excavation construction and mud-water balance pipe jacking two construction programs, through the comparison of the two construction programs, decided to take the pipe jacking method for sewage pipeline construction. The advantages of the mud-water balance pipe jacking method are listed in detail. After this method is adopted, the good economic benefits have been obtained.
