Sand setting structure for hilly and mountainous areas

By using an open-type sedimentation structure and a horizontal impeller design, the problems of low sedimentation rate and large footprint of sedimentation ponds in hilly and mountainous areas have been solved. This has enabled efficient sedimentation and separation of floating matter under different water flow conditions and simplified the maintenance process.

AI Technical Summary

Technical Problem

Existing sedimentation ponds in hilly and mountainous areas have problems such as crude water inlet and outlet settings, low water pressure elimination, low sedimentation rate, large area, and difficulty in handling floating objects, especially when the rainfall/water flow is small or large.

Method used

It adopts an open-type sedimentation structure and a horizontally arranged impeller structure, including flexible and rigid blades. The flexible blades can be bent to adapt to different water flow conditions. Combined with the design of the retaining wall and slope, it can achieve effective sedimentation and energy dissipation.

Benefits of technology

It can effectively settle sand under different rainfall/water flow conditions, improve the sand settling rate, prevent sand particles from splashing, reduce the footprint, separate floating objects, and is easy to maintain.

Abstract

The present application provides a sand setting structure for hilly and mountainous areas, comprising a sand setting pool arranged at the side of a slope or nearby, a water inlet channel and an overflow port arranged at the pool wall of the sand setting pool, a sand discharge channel arranged at the low point of the sand setting pool, and a horizontally arranged impeller structure arranged in the chamber of the sand setting pool, wherein the sand-containing water flow entering the sand setting pool through the water inlet channel can fall on the impeller structure and drive the impeller to rotate. The present application is especially suitable for sand setting in hilly and mountainous areas, can effectively set sand under the condition of small rainfall / water flow, and has the advantage of better energy dissipation effect.
