Water seepage pipe, revegetation area water-saving irrigation system and construction method thereof

Abstract

The invention discloses a water seepage pipe, a revegetation area water-saving irrigation system and a construction method thereof and solves the problem that existing water seepage pipes waste water resources and are poor in irrigation effect. The water seepage pipe comprises a pipe body provided with multiple water seepage holes in the pipe wall and a water seepage filler arranged inside the pipe body. Through the water seepage filler arranged inside the pipe body, irrigation water entering the water seepage pipe slowly seeps out, water resources are saved, and absorption by vegetation is facilitated; the irrigation water entering the water seepage pipe is given convenience to diffuse around and enabled to seep out from the water seepage holes in the pipe body, so that irrigation effect is good.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation, and in particular relates to a seepage pipe, a water-saving irrigation system for a vegetation restoration area and a construction method thereof. Background technique [0002] For rocky or spray-mixed high and steep slopes caused by large-scale excavation, ecological restoration is required, and water is an extremely critical factor for ecological restoration. Because the slope is relatively high and steep, and after the spray-mixed support measures are implemented, the substrate for vegetation growth is almost completely blocked, and the maintenance of vegetation restoration often requires a lot of manpower and material resources, and most of the slopes are difficult to reach the slope surface for manual maintenance. Irrigation and maintenance. [0003] At present, for the ecological restoration measures of high and steep slopes, the initial maintenance mainly depends on manual irrigatio...

Problems solved by technology

The first irrigation method is only suitable for roadside slopes with convenient transportation, and has great limitations. At present, most high and steep slopes of power stations are not suitable for this method; the second irrigation method requires large investment and difficult maintenance. It needs to be laid in the early stage Irrigation pipelines and water pumping need to be maintained in a timely manner in the later stage of operation, which requires a large investment. At the same time, after the completion of the project, the roads cannot be preserved, and the maintenance work cannot be carried out. Moreover, most of the irrigation water is extracted ditch water or river water, which has not been filtered. In addition, the existing seepage pipe generally has a structure with multiple seepage holes on the pipe wall of the pipe body, and the irrigation water can directly overflow through the seepage holes, and most of them are drained. Evaporated, only a small amount is absorbed by vegetation, and the waste of water resources is serious; and irrigation water often overflows from the seepage holes on the lower side, and the irrigation effect is not good
