在治理渍涝灾害工程中，需要排除农田中多余的水分。采用它沟进行排水，也是行之有效的工程措施之一．它沟是采取渗流输水的方式，排除农田中多余水分、控制地下水位，从而达到消除波涝灾害目的的地下工程。在官沟修建的施工过程当中，有以下四个方面的问题应当注意；一、盲沟 In the management of waterlogging disaster projects, the need to rule out excess water in farmland. It is also one of the effective engineering measures to use it for drainage. Its ditch is a way to seepage and water conveyance, eliminate excess water in farmland, control groundwater level, so as to achieve underground engineering for the purpose of eliminating floods and floods. In the construction of the official ditch construction process, the following four aspects should be noted; First, blind ditch
