E. deepening the anti-seepage curtain of the dam to the relative water-resisting layer and constructing an independent drainage system of seepage control in front of the underground powerhouse.

对百色水利枢纽地下厂房的渗控方案，提出了加深大坝防渗帷幕至相对隔水层方案和厂前设置独立的防渗排水系统2个方案。

Result showed that, with the controlled facility, the water storage is about 19×10^3 m^3/km of in the main drainage canal, the groundwater table in farmland is raise about 0.3 to 0.5 m and the crop water use is increased about 50 to 80 mm comparing with the non controlled main drainage canal.

结果表明，单位长度大沟年调蓄水量为1.9×10^4立方公尺/km左右，其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m，每年可增加作物对地下水的直接利用量50~80 mm，区域年农田水资源调控总量110 mm左右，约占当地年均降雨量的13%；只要控制合理、管理得当，不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。

In our country, it is quite serious that drainage pipe walling up and cracking produces pollution and direct or indirect economy loss, so it is very imperative that we will research and design a drainage pipeline automation testing system.

摘要在我们国家，地下排水管道堵塞或者破裂造成的污染，直接或间接造成的经济损失是相当严重的，所以研究和设计一台排水管道自动检测系统很有必要。
