暗管排水工程是近年来发展起来的一种新型排水设施，它占用耕地少，便于机械化操作，并能保持一定的排水深度。它适于在地势低平，排水不畅和土壤盐分较重的地区发展。暗管排水工程的施工程序大体上可分以下几步：1．定线根据设计方案定出吸水管和集水管的位置。设计时要根据土
The concealed pipe drainage project is a new type of drainage system developed in recent years. It takes up less arable land, is convenient for mechanized operation and can maintain a certain drainage depth. It is suitable for development in low lying, poorly drained and heavily saline soil areas. Hidden tube drainage project construction process can be divided into the following steps: 1. The alignment determines the position of the suction and collector pipes based on the design. Design according to soil
