Description

Mutually embedded plant-growing retaining wall structure

Technical Field

The application relates to the technical field of river channel revetments, in particular to a mutual embedded vegetation retaining wall structure.

Background

The river course revetment mainly includes natural revetment, concrete revetment, gabion revetment, vegetation revetment and geotechnique's fabric revetment etc.. Wherein, natural revetments utilize natural materials, such as stone, timber, bamboo, etc. to construct natural river banks, imitate natural river topography, let vegetation naturally grow, reach the protective effect. Natural revetments have little impact on the environment but require long-term maintenance. The concrete slope protection uses concrete to pour the river bank, so that the erosion caused by water flow scouring can be effectively prevented. Although firm and durable, the concrete slope protection possibly has a certain influence on the ecological environment, and the construction difficulty is high. The gabion revetment can pack the stone into the cage woven by the wire netting, forms the gabion revetment. The plant material has better anti-scouring capability, can provide a growth space for plants, and combines engineering and ecological advantages. But has higher cost and large construction workload, and is not suitable for the river channels with more sandy soil layers and river banks. Vegetation slope protection can be realized by planting vegetation on a bank slope, such as turf, trees and the like, and the mechanical effect and the hydrologic effect of plant roots are utilized to carry out slope protection soil fixation and prevent water and soil loss. However, in the early growth stage of plants, the protection capability is weak, and a long time is required to form a stable slope protection structure.

Therefore, the river channel revetment can be realized by adopting the mode of the concrete revetment and the vegetation revetment, but compared with the mode of singly using the concrete revetment by using the mode of combining the concrete revetment and the vegetation revetment, the combined use of the vegetation revetment needs more construction steps, such as slope preparation, concrete construction, vegetation planting, maintenance management and the like, and the difficulty and the complexity of construction are increased.

By arranging the square piles 1 in the side slope, various forces from water flow or geological activities can be effectively resisted, and therefore safety and stability of two banks of a river channel are ensured. After the square pile 1 is arranged at a proper position along the river bank in a driving mode, the square pile 1 is arranged around the square pile 1, the ground is leveled at the joint of the square pile 1 and the ground, a foundation pit is excavated, the first cushion layer 2 is formed by binding reinforcing steel bars and pouring concrete, the stability of the embedded planting retaining wall structure can be improved, and meanwhile, the concrete has a strong flood discharge and drainage function because the water flow velocity at the bottom of a river is greater than that at the surface of the river, so that the embedded planting retaining wall structure can bear a large water flow impact.

The cofferdam is a temporary enclosure structure, and can prevent water and soil from entering the built position of the embedded plant-generated retaining wall structure when the embedded plant-generated retaining wall structure is built, so that the construction area is ensured to be dry, and the water and the foundation pit are conveniently drained and excavated. The height of the cofferdam is higher than the highest water level which can occur in the construction period, so that the safety of construction is improved.

In some embodiments, as shown in fig. 2, the block 4 includes a first hole 401 and a second hole 402, the first hole 401 having a rectangular cross section and the second hole 402 having a hexagonal cross section. Wherein the first hole 401 may be used for filling pebbles and the second hole 402 may be used for planting aquatic plants. For example, pebbles may be placed in the first holes 401 after each layer of blocks 4 is laid, and the overall shear strength of the blocks 4 may be improved by filling pebbles in the first holes 401.

Meanwhile, after the building blocks 4 and the gravel layers 6 are paved, aquatic plants can be planted in the second holes 402, and the planted aquatic plants are mainly used for maintaining the stability of the embedded plant-growing retaining wall structure, enhancing the biodiversity and beautifying the environment. Specifically, the root system of the aquatic plant can effectively fix soil, reduce the scouring and erosion of water flow to the river bank, and improve the stability of the mutually embedded vegetation retaining wall structure.
