Combined type water-purifying spur dike group system for heavily polluted rivers

Abstract

The invention relates to a combined type water-purifying spur dike group system suitable for heavily polluted rivers. In the invention, a plurality of spur dikes are respectively arranged on two sides of a riverbank at certain intervals; the spur dikes obliquely extend into a riverbed from the riverbank to form a spur dike group; each spur dike consists of a water purifier, a support frame and anoperating bridge; and the dam axis of each spur dike has an included angle of 45-75 DEG with the flow direction of incoming water. The invention is beneficial to overcoming of the defects that the environmental effect of the spur dike (group) on purifying water, in particular the water of the heavily polluted rivers, cannot be fully exerted in the application of the traditional structure of the spur dike (group) and the like. The combined type water-purifying spur dike group system is beneficial to controlling and guiding of a water flow, has a little effect on changing the flow state of the water flow, has the advantages of relatively small scour pits of dike heads, strong flow turbulence capability, light scouring force in the front of the dikes and weak generated backflow, and can be used for changing the structure of the water flow, guiding sediment accumulation, adjusting and controling the depth of the riverbed and creating a plurality of river course environments; in addition, the combined type water-purifying spur dike group system is suitable for water purification of the heavily polluted rivers, and the water purifiers can be produced in batch and are simple in structure.

Description

technical field [0001] The invention relates to a river water purification system, in particular to a combined water purification spur group system suitable for heavily polluted rivers. Background technique [0002] The spur dam was originally a hydraulic structure that was connected to the embankment in a "T" shape to protect the water and soil of the embankment. It is currently a widely used river regulation and maintenance structure. Its main function is to protect the river rock from direct erosion by the incoming flow. Scrubbing damage, inducing sediment deposition, and regulating the depth of the river bed play a variety of important roles in flood control. In addition, since sediment deposits, deep and shallow water areas, wetlands and river beach depressions can be formed around spur dikes, various river environment can be created. [0003] In order to enhance the stability of spur dikes, a spur dike structure with geogrid rockfill occupation (ZL201020246893.5) disc...

Problems solved by technology

However, judging from the structure of spur dikes and the application of spur dike groups, the application of these technologies cannot give full play to the environmental effects of spur dikes (groups) to purify water bodies, especially to heavily polluted river water bodies
