一、排水管道水密性检查的必要性排水管道在施工、检修、整治完成后,交付使用前应进行水密性检查或者试验,其是竣工验收的主要内容。排水管道不严密会产生下列不良影响:1.污水会通过管道、井的不严密处渗出,污染土壤和地下水;2.雨水、污水通过管道、井的不严密处渗出,对土壤产生侵蚀,造成地面塌陷;3.在高地下水位地区地下水会通过管道、井的不严密处渗入管道内,增加排水量;4.植物根系会在管道、井的不严密处,
First, the need for drainage pipe watertight inspection Drainage pipe construction, overhaul, remediation is completed, before delivery shall be watertight inspection or test, which is the main content of the final acceptance. Drainage channel is not tight will have the following adverse effects: 1. Sewage will be through the pipeline, well insolent seepage, pollution of soil and groundwater; 2. Rainwater, sewage through the pipeline, wells out of tight, erosion of the soil , Resulting in ground subsidence; 3. Groundwater in the high groundwater level will be through the pipeline, not well-infiltration wells into the pipeline, increasing the amount of displacement; 4. Plant roots in the pipeline,
