Wave-eliminating bank protecting method of water purification type riverway

Abstract

The invention relates to a wave-eliminating bank protecting method of a water purification type riverway. The bank protecting method includes the following steps that the specification of bank protecting modules is determined, the bank protecting modules are prepared and installed, and bank protection ecology is built. Due to the fact that the wave-eliminating bank protecting modules are arranged nearby a water bank of the riverway and are used for retarding a water flow and decreasing the speed of the water flow, a new water flow boundary condition is created, and therefore the effects of controlling and guiding the water flow and protecting the bank are achieved. Meanwhile, a static water micro environment is formed between the wave-eliminating modules and the bank, aquatic plants can be planted, aquatic animals can inhabit in the static water micro environment, and therefore an aquatic animal and plant ecological system is formed, and pollution of bank slope point and face pollution sources on the water quality is relieved. According to the bank protecting method, high-specific-area stones such as zeolite, ceramsite and vermiculite are adopted, stability and water absorption capacity of gravel are achieved, and the effects of purifying water and improving the water quality are achieved by absorbing pollutant substances, such as heavy metal ions, N and P, in water.

Description

technical field [0001] The invention relates to a revetment method for a river system, in particular to a revetment method for a water-purifying river channel to eliminate waves. 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 good stability are usually used to resist water erosion. Form anti-scour r...

Problems solved by technology

It can protect the ecology and beautify the environment while preventing bank erosion, but its poor strength and durability limit its application in river sections affected by currents and wind waves.
