Embodiment Construction

[0027] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0028] like figure 1 As shown, an ecological sewage interception and slope protection structure with enhanced diversion and filtration, multi-level diversion grooves 1 are arranged at intervals along the river bank slope from top to bottom. The flow diversion groove 1 of the upper stage is connected with the flow diversion groove 1 of the lower stage through the flow diversion groove 2, and the flow diversion grooves 2 of the two adjacent flow diversion grooves 1 are arranged staggered left and right, and the stagger distance is at least 10m.

[0029] A rainwater inlet 3 is provided on the top of the first-stage diversion tank 1 to facilitate rainwater to enter the diversion tank 1 . A mesh cage 4 filled with pebbles is laid on the river bank slope where the diversion groove 1 and the diversion groove 2 are not provided. Biological ceramsite and gravel ...

Abstract

The invention discloses a slope protection structure with enhanced diversion, filtering and ecological sewage interception effects. Multiple stages of diversion trenches are sequentially arranged at intervals along a river channel bank slope from top to bottom; the diversion trench of the previous stage and the diversion trench of the next stage are connected through a diversion channel; the diversion channels of the diversion trenches of the adjacent stages are horizontally staggered, and a staggered distance is at least 10 m; a rainwater inlet is arranged in the top of the diversion trench of the first stage; a mesh cage filled with cobblestones is laid on a part, which is not provided with the diversion trench and the diversion channel, on the river channel bank slope; biological ceramsite and gravel are placed in the diversion trenches of the upper half part of the river channel bank slope; biological ceramsite and coarse sand are placed in the diversion trenches of the lower halfpart of the river channel bank slope; green plants are planted in each stage of diversion trench; and meanwhile, the invention further discloses a slope protection system with the enhanced diversion,filtering and ecological sewage interception effects. The system comprises a plurality of crescent array diversion, sewage interception and purification groups which are arranged at intervals in a water channel along a water flow direction. The structure and the system have the enhanced diversion, filtering and ecological sewage interception effects.

Description

technical field [0001] The invention relates to the technical field of river bank slope treatment and water quality treatment in the river. Background technique [0002] Human beings' governance of river courses has gradually developed into the stage of ecological restoration after going through the stages of engineering governance and natural transformation. River ecological restoration refers to using the principles of ecosystems to use various methods to restore the biological population and structure of the damaged water system, rebuild a healthy aquatic ecosystem, restore and strengthen the main functions of the water ecosystem, and enable the ecosystem to achieve overall A virtuous cycle of coordination, self-maintenance and self-succession. [0003] Most ecological slope protection technologies based on water environment restoration use gabion cages (also known as ecological gabion nets, gabion nets), that is, steel wires are woven into rectangular cages of different...
