Abstract

The invention discloses a waterlogging controlling and reducing device, and belongs to the technical field of farmland water conservancy projects. The device comprises a drainage pipeline unit, a water flow control unit and a gravel unit, wherein the water flow control unit comprises a drainage piece, a drainage support piece and a drainage control piece, the upper end of the drainage piece communicates with the lower end of the gravel unit, the lower end of the drainage piece communicates with the drainage support piece, and the drainage support piece communicates with the drainage pipeline unit; the drainage control piece is arranged in the drainage piece, and the drainage control piece is used for controlling waterlogging on the ground surface to enter the drainage pipeline unit and isused for preventing water flow in the drainage pipeline unit from entering the drainage support piece; the drainage pipeline unit is used for being laid below ground; and the upper end of the gravel unit communicates with the ground. According to the waterlogging controlling and reducing device, the occupied cultivated land is little, the drainage cost is low, and the construction difficulty is small.

Description

Technical field [0001] The invention relates to the technical field of farmland water conservancy engineering, in particular to a waterlogging and waterlogging reduction device. Background technique [0002] The waterlogging disaster formed by rainfall and drainage is an important factor affecting my country's food production and the safety of rural infrastructure. Waterlogging disasters include waterlogging disasters and waterlogging disasters. Waterlogging disasters are disasters caused by excessive accumulation of water after the rain, and the surface drainage system cannot eliminate them in time; waterlogging disasters means that the groundwater level is too high, resulting in soil moisture often being saturated. The deterioration of physical and chemical properties, the imbalance of water, heat, air and nutrients, affects the growth of crops or endangers the survival of crops. Under normal circumstances, in most areas, waterlogging and waterlogging exist at the same time, a...
