Problems solved by technology

[0008] Since the existing technology has not been able to form a comprehensive watershed engineering management system, and the water and soil loss of river valleys, slopes, and edge of plateau beams within the watershed has not been coordinated, coordinated and comprehensive engineering control, so various single engineering measures There are great limit

Embodiment Construction

[0035] The construction of the weir system in the basin is to use the muddy water transported by the runoff of the river valley to fill the mold bag, build the mold bag body, blow fill, and deposit soil weirs, build multiple single weirs and ladder weirs, and use the sediment carried by runoff and floods to deposit multi-layered river valleys The plains and river bank terraces constitute the river valley weir system; the first weir is built on the slope to store the slope runoff muddy water, and the mold bag is filled through the overflow of the first weir and the self-flow of the pipeline, and multiple ditches and slope weirs are constructed. Silt slope valleys and slope terraces to form the slope weir system; build ditches and slope weirs at the edge of the plateau and beams to restore and maintain the complete flat shape of the edge of the plateau and beams, and construct trap weirs to trap the edges of the plateau beams, The muddy water on the surface of the tableland beams...

Abstract

The invention discloses a basin weir system used to treat soil and water loss and the construction method thereof, and is an engineering type measure of treating water erosive soil and water loss. The invention proposes to use the natural energy and sediment resource after rain to fill mold bags with the earthwork cloth as the packing material to construct a mold bag body to blow-fill and fill up the soil body. Single-weirs and slope weirs are constructed in the gullies of river channels and branches, and multi-level valley plains and bank terraces are deposited, thereby forming a river channel gulley weir system; initial weirs are arranged on the slopes to store the slope radial flow sludge water, ditch weirs and slope weirs are constructed by organizing the overflow of the initial weirs and paving pipelines to self-flow to fill the mold bags, the gullies and the terraces at the lower slopes are deposited as well as blown and filled, thereby forming a slope weir system; ditch weirs, slope weirs and trap weirs are constructed at the edge zones of tablelands and ridges, the intact flat form of the edges of the tablelands and the ridges is restored and retained, thereby forming a tableland ridge edge weir system; the river channel gulley weir system, the slope weir system and the tableland ridge edge weir system form the basin weir system, thereby realizing the intention of roundly treating soil and water loss with engineering measures.

Description

technical field [0001] The invention relates to a watershed weir system and a construction method thereof for controlling water erosion soil erosion in the technical field of water and soil conservation. Background technique [0002] Soil erosion is the number one ecological environment problem in our country. The natural causes of soil erosion are mainly water, wind, gravity and freeze-thaw erosion. The meaning of soil erosion mainly refers to soil erosion, and the control of water and soil loss is mainly aimed at the control of soil loss. Water erosion and soil loss are mainly controlled by plant measures, farming measures and engineering measures. [0003] Among various types of soil erosion, only water erosion can cause large-scale loss of water and soil at the same time, and its occurrence range is the most extensive. Even in some arid areas, due to the lack of vegetation, concentrated rainstorms and other reasons, the situation of soil er...
