近年来,城镇环境工程建设发展迅速,作为配套设施的排水管网设计与建设资金、居民生活及市容环境关系密切。故,合理确定设计管径与管道埋深是排水管网设计中关系到整个社区工程设施得以正常使用的重要保障之一。因此构成排水管道工程的沟槽开挖与回填、沟槽支撑、地下水排除、管基处理及管道铺设和检查井砌筑等各个施工环节均应重视质量。它涉及到以下几个方面的问题。 1.排水管道的管径与埋深及造价的关
In recent years, the rapid development of urban environmental engineering construction, drainage facilities as ancillary facilities design and construction funds, living and city environment closely related. Therefore, it is one of the important guarantee that the design of drainage pipe network is related to the normal use of the entire community engineering facilities. Therefore, the construction of the drainage pipe project trench excavation and backfill, trench support, groundwater removal, pipe foundation treatment and pipeline laying and inspection wells masonry and other construction links should pay attention to quality. It involves the following aspects. 1. Drainage pipe diameter and depth and cost of the off
