Slope surface multifunctional longitudinal drainage structure for comprehensive treatment of small watershed

Abstract

The invention discloses a slope surface multifunctional longitudinal drainage structure for comprehensive treatment of small watershed. The slope surface multifunctional longitudinal drainage structure comprises a multifunctional road arranged in the inclined direction of the slope surface, wherein the multifunctional road is composed of a plurality of steps arranged laterally and fences arrangedon both side edges of the steps; a sedimentation basin is arranged in the multifunctional road or outside the multifunctional road; and the steps and the fences together form runoff sediment channels,and the runoff sediment channels communicate with the sedimentation basin. The slope surface multifunctional longitudinal drainage structure has high structural strength and high stability, and is not prone to being destroyed by runoff. A drainage system is organically integrated with the road and the sedimentation basin. The design type is novel, the structure is compact and reasonable, resources are saved and the occupied land area is small, and the utility efficiency is high; an effective slope surface drainage function can be achieved in the rainy season, a sedimentation effect on sediment in the runoff is achieved, and the runoff sediment-carrying capacity is effectively reduced; and at the same time, the function of producing roads is achieved, and the problem of land occupation caused by laying horizontal drainage ditch entrances on both sides of traditional roads is reduced.

Description

technical field [0001] The invention belongs to the technical field of comprehensive management of small watersheds, and in particular relates to a multifunctional vertical drainage structure on slopes used in comprehensive management of small watersheds. Background technique [0002] my country has a long history of small watershed management focusing on the prevention and control of water and soil erosion. After more than 30 years of exploration and practice, the comprehensive management of water and soil loss based on small watersheds has gradually explored governance concepts, measures and management systems that adapt to my country's actual conditions, and has achieved It has rich governance experience and significant ecological, social and economic benefits. The governance model has become increasingly mature. However, while affirming the achievements, there are also many weak links and emergent problems that need to be resolved urgently. [0003] In the comprehensive ...

AI Technical Summary

Problems solved by technology

[0003] In the comprehensive treatment of small watersheds, the layout of vertical drainage measures must be considered in the treatment of slopes with a slope ≥ 15°. At present, there are two conventional layouts. One is separate layout without supporting pedestrian production roads, which is inconvenient for production; the other is the entrance of vertical and horizontal drainage ditches. Arranged side by side with the production road, that is, the entrance of the vertical and horizontal drainage ditch is set on one side of the road or on both sides of the road, occupying valuable mountainous land resources

In terms of material structure, cement prefabricated parts are mostly used, and the side walls or bottom are often hollowed out due to runoff, causing damage
