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 device for removing waterlogging and reducing waterlogging. Background technique [0002] The waterlogging disaster caused by rainfall and drainage is an important factor affecting the safety of my country's grain production and rural infrastructure. Waterlogging disasters include two parts: waterlogging disasters and waterlogging disasters. Waterlogging disasters are caused by excessive water accumulation after rains, and the ground drainage system cannot remove them in time; waterlogging disasters refer to soil moisture that is often saturated due to high groundwater levels. Deterioration of physical and chemical properties, imbalance of water, heat, air and nutrients, affecting crop growth or endangering crop survival. In general, waterlogging and waterlogging exist simultaneously in most areas, and it is difficult to separate them completely,...
