TECHNICAL FIELD

[0001] The utility model belongs to the technical field of revetment structure, concretely relates to a concrete vegetation revetment structure based on 3D printing. BACKGROUND

[0002] The revetment structure is an engineering structure for protecting the stability of the slope, and the main purpose is to prevent the destruction and instability of the slope caused by natural factors or human factors. The Three Gorges Reservoir is operated according to the scheduling plan of "storing water in winter and discharging water in summer", and the reservoir water level periodically rises and falls between the normal storage level and the flood control limit level all the year round, forming a drawdown zone up to 30 meters. This periodic water level difference has a great impact on the slope vegetation. When the water level drops, the slope soil is eroded and eroded by the water flow, leading to soil loss and exposure of the vegetation root system, further exacerbating the vulnerability of the vegetation. In addition to the periodic water level difference, wave erosion is also an important factor affecting the vegetation ecology of the Three Gorges Reservoir drawdown zone slope. During the storage period, the water flow in the reservoir area is fast, and the waves directly impact the slope vegetation, causing the plant leaves, branches and even the whole plant to be washed away, seriously affecting the coverage and biomass of the vegetation. Wave erosion also makes the slope soil loose, reducing the soil erosion resistance and further exacerbating soil erosion and vegetation damage. The existing revetment engineering structure is relatively primitive, which is suitable for ordinary rivers without major problems. It is suitable for the dam section of the reservoir area with fast flow and large periodic water level change. There is a problem of poor safety, and a more delicate internal structure of the revetment engineering is needed, and more advanced materials are needed for the construction of the revetment engineering. Therefore, a concrete vegetation revetment structure based on 3D printing is needed to solve the above problems. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a concrete vegetation revetment structure based on 3D printing. The device aims to provide a new type of concrete vegetation revetment structure, which can be made by 3D printing equipment to solve the problem of backwardness of the existing revetment engineering structure and the inability to adapt to the water regime of the reservoir dam area.

[0004] To solve the above technical problems, the utility model adopts the technical scheme of:

[0005] The concrete vegetation revetment structure based on 3D printing comprises a revetment brick, and the top of the revetment brick is provided with an extended retaining brick. The size of the extended retaining brick is half of the revetment brick, and the interiors of the revetment brick and the extended retaining brick are cavity structures.

[0006] Preferably, the inner walls of the revetment brick and the extended retaining brick are provided with first water inlets, and the outer walls of the revetment brick and the extended retaining brick are provided with water outlets.

[0007] Preferably, a second water inlet is arranged on the outer wall of the slope protection brick away from the one end of the extended retaining brick, and a water permeable retaining column is arranged in the slope protection brick, and a water permeable hole is arranged on the outer wall of the water permeable retaining column, and the water permeable retaining column is in communication with the inner cavity of the slope protection brick.

[0008] Preferably, the hollow interior of the slope protection brick is a plant growth space, and is filled with several layers of cement-based habitat substrates, and the surface of the cement-based habitat substrates is sown with slope protection plant seeds.

[0009] The slope protection brick has the following beneficial effects:

[0010] The extended retaining brick can block the impact force of water, effectively reducing the damage of water impact to the vegetation, and the water level that overflows the extended retaining brick can be accumulated in the interior of the slope protection brick, and the water can be introduced into the interior of the slope protection brick and the extended retaining brick through the first water inlet, and then discharged through the water outlet, thereby effectively solving the problem that the water overflows the extended retaining brick and is accumulated in the slope protection brick for a long time, causing the death of the vegetation.
