Problems solved by technology

[0004] Vegetation-type revetment mainly uses plants with well-developed root systems and plant materials to fix the soil on the bank slope, such as wooden piles / twigs, reeds, vetiver, palm fiber mats, three-dimensional geonet mats, ecological bags, etc. The ecological protection of such structures The landscape and the effect of reducing ship waves are better, but the anti-scouring ability and the overall stability and durability of the revetment structure are difficult to guarantee
Hard revetment is mainly composed of concrete structures or reinforced concrete structures, such as imitation wood piles, planks, gabion cages, dry or mortar block stones, "honeycomb" retaining walls, concrete interlocking face protection blocks, etc. The anti-scouring ability of the structure is strong, and it is easy to meet the overall stability of the revetment, but the ecological landscape and the effect of reducing ship waves are poor

Embodiment Construction

[0023] The section form of the revetment structure of the present invention is a composite structure with a steep bottom and a gentle top, and a first-level hard revetment 1, a revetment platform 2 and a second-level flexible revetment 3 are sequentially arranged from bottom to top.

[0024] The first-level hard revetment adopts a combined structure of prefabricated permeable reinforced concrete boxes and prefabricated reinforced concrete inserts. The construction process is: site cleaning, obstacle removal, construction drainage → temporary construction of cofferdams → earthwork deployment, foundation pit excavation → Drainage of foundation pit → pouring of concrete bottom slab → prefabrication, transportation and installation of reinforced concrete box and insert plate → layout of settlement joints and drainage facilities behind the wall → backfilling of stones in the box → laying of geotextile → earthwork backfilling → concrete roof pouring → backfilling soil and plant reeds...

Abstract

The invention discloses an ecological bank protection structure combining boxes and insertion plates. A first-level hard protection bank, a bank protection platform and a second-level flexible protection bank are sequentially arranged from bottom to top. The first-level hard protection band is of a structure combining the prefabricated water-pervious steel bar concrete boxes and the insertion plates, each box is almost a square hollow box, the insertion plates are square, every two adjacent boxes are connected through the insertion plates, each insertion plate is fixed in clamping grooves in the middle of the outer walls on the two sides of the corresponding box, the crest level of each box is 0.4 m-0.6 m lower than a normal water level, the insertion plates are 0.8 m-1.2 m higher than the corresponding box and are 0.4 m-0.6 m away from the water facing vertical face of the corresponding box, a grid-type wave eliminating structure is formed on each water facing vertical face, and an open-type plate wave-resisting structure is formed on the upper portion of each structure. The tops of the boxes are covered with soil so that reeds and other protection plants can be planted, and concrete is poured on a bywater side of each box for blocking soil. Ship waves can be effectively reduced, the variety of off-shore water currents is improved, materials are saved, project manufacturing cost is reduced, and ecological benefits and economic benefits are both obtained.

Description

technical field [0001] The invention relates to an ecological protection method for revetment of inland waterways, in particular to a combined ecological revetment structure suitable for restricted waterways, belonging to the technical field of building construction for inland waterway regulation. Background technique [0002] In navigable rivers and artificial waterways, in order to prevent water and soil erosion, ship wave erosion, and ship impact from damaging the river bank, high-strength materials such as stones, concrete, and steel bars are often used to harden the waterway bank slope. However, as people's expectations for the ecological environment are getting higher and higher, these hard revetments have separated the relationship between the water body and the soil, and the material and energy circulation system between water-soil-plant-biology is destroyed, causing threats to the ecological environment. ; The extensive application of gray hard materials such as con...
