The water and soil loss of the waste slag field comprises hydraulic erosion, gravity erosion, mixed erosion and wind erosion, wherein the influence of the hydraulic erosion is the greatest, so that the flood control drainage engineering of the waste slag field is extremely important for the safety and stability of the slag field.
The existing flood control and drainage engineering of the waste residue field mainly comprises a flood control dam, a flood drainage canal (ditch), a culvert and the like, wherein the flood control dam mainly comprises a soil dam, a rock-fill dam, a slurry stone-fill dam, a concrete dam and the like, and is mainly used for blocking water coming from the upstream of the waste residue field and guiding the water into a tunnel, a culvert, the flood drainage canal and other drainage measures; besides adopting a flood-stopping dam to stop flood, the inlet of the flood discharging canal can also adopt a horn mouth or splayed guide wing wall to guide upstream water to enter the groove. However, according to the engineering field implementation, the incoming water structure at the upstream of the slag field is difficult to finish in a relatively low cost manner due to the limitation of the land, insufficient bearing capacity of the foundation and the like.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide the upstream water guide structure of the waste slag field, which is not easily influenced by external factors such as terrain, foundation requirements and the like, and has low construction cost and good water drainage effect.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
an upstream water guide structure of a waste slag field comprises a water collecting section, a water collecting gradual change section, a drainage canal and a stone slag compacting body; the water collecting section is formed by digging downwards to stick to a slope and protecting the bottom, the water facing side slope sticks to the slope along the original terrain slope, the back water side slope sticks to the slope along the ballast compacting body, and the height of the back water side slope is higher than that of the water facing side slope; the catchment gradual change section is connected with the catchment section and the drainage canal; the drainage channel is positioned on one side of the ballast compact and extends downstream.
Further, a block stone bottom guard is arranged on the outer side of the water-facing side slope of the water collecting section, and a sand gravel reverse filter body is arranged at the bottom of the block stone bottom guard.
Further, the junction of the catchment transition section and the drainage channel is provided with a structural seam and is provided with water stop.
