Description

A drainage structure for land consolidation

technical field

The utility model relates to the field of land consolidation equipment, in particular to a drainage structure for land consolidation.

Background technique

With the development of economy and society, land, as the carrier of all economic and social activities, becomes increasingly scarce. Land consolidation is the most important activity for human beings to change the way of land use, and it has also become the most important way to alleviate the conflict between man and land. In the process of land improvement, for some land with serious water accumulation, drainage treatment is required. At present, the commonly used drainage method is to use water pumps and drainage pipes to pump and drain water. When the water accumulation area is far away from the drainage ditch, multiple drainage pipes need to be connected end to end through the flange to increase the drainage distance. However, this drainage method can only enter water at the end of the drainpipe. For landforms where water accumulates at multiple points, workers need to frequently adjust the position of the end port of the drainpipe for drainage. This operation method is inefficient and labor-intensive. Of course, it is also possible to connect a tee to increase multiple water inlets during drainage, but it is more troublesome to connect, and a separate filter structure needs to be installed at each water inlet to prevent blockage caused by weeds and silt, and the cost is high.
