[0002] Irrigation ditches are responsible for providing water to crops; drainage ditches, in addition to the task of drainage, are also responsible for preventing waterlogging, alkali prevention and alkali treatment. The design water level of the drainage ditch must be able to discharge the designed drainage flow in time during heavy rain to ensure that no waterlogging disasters are caused by the accumulation of waterlogging water, and the ditch must be able to lower and control the groundwater level to meet the requirements of preventing waterlogging, alkali prevention and alkali treatment. Therefore, the bottom elevations of open drainage ditches and underground drainage pipes are relatively deep, and the excavation volume is large.

[0003] In the past, the traditional irrigation and drainage separation mode had the problems of large structural engineering, large amount of excavation and backfilling during construction, high investment, and increased land area for drainage projects, which not only reduced the cultivated land rate but also greatly increased the project investment.
