ZM系列渠道防渗减压阀的研究和应用

Study and Application of the ZM Series Pressure Relief Valve in Canal Seepage Control

挖方或傍山衬砌的渠道,往往因地下水的挤压使渠底板开裂、鼓泡掉块、翻倒等。为保证渠道稳定,湖南省水科所研制出 ZM 系列渠道防渗减压阀.其基本构造为:在聚氯乙烯硬塑管模内,装入单向排水的逆止阀,管的两端用土工织物封盖。其性能良好,适用范围广,能有效地排除地下水压力对防渗层的破坏,而渠内过水时水流不外渗。

The canal bottom plate cracking and side slope peeding off are often happened because of the groundwater extruding in the cut and hill side lining canal.The ZM series pressure relief valve in canal seepage control has been developed for insuring the canal stability by the Hunan Institute of wa- ter conservancy.The basic structure is that a single direction inverted valve is installed in the hard PVC plastic pipe and the membrance is covered in the two ends of the pipe.This device has fine function and broad application field.The groundwater pressure damage to the lining can be lowered effectively and the canal water can not be seeped into the canal banks.
