Wave eliminating bank protection module and bank protection structure for water purification type river channel

Abstract

The invention relates to a wave eliminating bank protection module and a bank protection structure for a water purification type river channel. The bank protection module comprises a net cage which is woven through metal wires and is located on the outer layer, and a gravel structure arranged in the net cage in a filling manner. The bank protection module further comprises a purifying layer arranged on the surface layer of one side in the net cage in a filling manner. The bank protection structure comprises at least two rows of bank protection modules arranged in a near river bank in a delta shape. A static water area is formed between the bank protection modules and the river bank, and aquatic plants are planted in the static water area. According to the bank protection structure for the water purification type river channel, a novel water flow boundary is built, and the functions of controlling and guiding water flow and protecting the bank are achieved; and in addition, stone such as zeolite, ceramsite and vermiculite with high specific surface area is adopted, the functions of stabilizing gravel and absorbing water force can be achieved, the functions of purifying a water body and improving water quality can be achieved by absorbing pollutants such as heavy metal ions, N and P in water.

Description

technical field

[0001] The invention relates to the technical field of bank revetment construction of rivers and other water systems, in particular to a water-purifying river channel wave-dissipating bank revetment module and a bank revetment structure. Background technique

[0002] The erosion of the river bank caused by waves and currents caused by wind, boats, etc. can cause the river bank to collapse or silt up, resulting in the degradation or silting of the river bank. This factor is one of the important reasons leading to the instability of river bank slope. In order to protect the safety of the river bank slope, maintain the water ecosystem and beautify the environment, revetment technology has been widely used.

[0003] Generally speaking, structural revetment is suitable for river sections with complex water flow and high flow velocity, and is obviously affected by water flow and wind waves. Stone masonry, concrete blocks, steel sheet piles and other entities with ...

Examples

Embodiment 1

[0026] The invention provides a water-purifying river channel wave-dissipating bank protection module, such as figure 1 Shown, wherein shows a preferred embodiment of revetment module of the present invention. The revetment module includes a mesh cage 1 made of outer metal wires and a gravel structure filled in the mesh cage 1. The mesh cage 1 is a wooden horse-shaped structure with a trapezoidal longitudinal section. The gravel structure includes The first gravel layer 2 in the lower layer and the second gravel layer 3 arranged in the upper layer, the first gravel layer 2 is 3-30 cm particle size graded gravel, and the second gravel layer 3 is 15-30 cm particle size graded gravel, the thickness ratio of the first gravel layer 2 to the second gravel layer 3 is (1:1) to (3:2), and the revetment module also includes a The purification layer of the side surface layer is a mixture of one or more of zeolite, ceramsite and vermiculite with a particle size of 3-10 cm.
