Sand-blocking type soil and water conservation ecological bank protection

Abstract

The invention provides a sand-blocking type soil and water conservation ecological bank protection which includes a retaining wall with an empty box structure arranged along an edge water of a riverway. The retaining wall comprises a bottom plate located at the bottom of the riverway, a front baffle and a rear baffle arranged on the bottom plate, wherein the front baffle is located on the water facing side of the retaining wall, the rear baffle is located on the soil retaining side of the retaining wall, and the elevations of the front baffle and the rear baffle are lower than a normal water level of the riverway; the height of the front baffle is higher than that of the rear baffle, an accommodating cavity is formed in the retaining wall, the accommodating cavity is provided with soil materials, and submerged plants are planted on the soil materials. The sand-blocking type soil and water conservation ecological bank protection is beneficial to water and soil conservation and reducingthe amount of sludge in the riverway; through optimization of the internal structure and overall arrangement of bank protection, the space above the soil materials in the retaining wall of the empty box forms a retard mud sand pit; through retention of terrestrial plants and aquatic plants, water flow becomes slow; and through high and low arrangement of the front and rear plates, silts and scrapsare deposited in the retard mud sand pit as soon as possible when passing, and it is beneficial to soil and water conservation and reducing the amount of the sludge in the riverway.

Description

technical field [0001] The invention relates to the field of ecological river regulation, in particular to a sand-retaining soil and water conservation ecological revetment, which is suitable for preventing water and soil erosion, reducing river siltation and dredging costs, and rivers with high requirements for landscape ecology and deformation control of retaining walls. Background technique [0002] The traditional cantilever or buttress retaining wall is a reinforced concrete hard revetment, which is widely used in various projects. The retaining wall body and the retaining wall bottom plate form a closed barrier, which hinders the water and soil exchange on both sides of the wall and seals the The soil on which aquatic plants and animals depend for their survival blocks the original ecological chain of river courses and embankments, lacks ecology, and has poor landscape quality. Slope-type ecological revetment, due to the erosion of rainwater flow, the sediment and plan...

[0002] The traditional cantilever or buttress retaining wall is a reinforced concrete hard revetment, which is widely used in various projects. The retaining wall body and the retaining wall bottom plate form a closed barrier, which hinders the water and soil exchange on both sides of the wall and seals the The soil on which aquatic plants and animals depend for survival blocks the original ecological chain of river courses and embankments, lacks ecology, and has poor landscape quality

Slope-type ecological revetment, due to the erosion of rainwater flow, the sediment and plant debris on the ground and revetment can easily enter the river with the water flow, on the one hand causing ground soil erosion, on the other hand, the water flow in the plain river network area is slow, mud Sand and plant debris silt to the bottom of the river. After a long time of silting, the cross-section of the river channel decreases, which reduces the regional flood control standards and puts pressure on regional flood control.

Therefore, the government has to dredge the river every once in a while, which costs a lot of money and a lot of manpower and material resources. In addition, no matter whether the dredger is used for underwater dredging or dry dredging, it will cause huge damage to the river ecology.
