Description
Technical Field
The utility model relates to a field of river course protection especially relates to a prefabricated block of frame shore protection bank protection and assembly thereof.
Background
In water conservancy projects, inland rivers projects and highway projects, if retaining walls and wave-retaining wall structures are not arranged on the riverway, urban inland rivers, two sides of highway pavements and the water-facing side of a breakwater, water and soil loss is easily caused, and bank slopes collapse, so that the retaining walls and the wave-retaining wall structures need to be built.
Traditional retaining wall is mostly cast in situ concrete, and the wave wall is prefabricated solid block. A large amount of concrete is needed in the structure, and the underground water at two sides of the river channel cannot be communicated with the river channel due to the watertight characteristic of the concrete. In rainy season, the water level of the river rises, so that underground water cannot be supplied, and waterlogging is easily caused; in dry seasons, the water level of the river is reduced, underground water cannot supply the river, and the river forms dead water to generate black and odorous water. The existing frame type slope protection technology is a simple concrete outer frame which is parallel to a slope surface, and a bank slope is fixed by compacting a soil body or spraying concrete. The slope protection in this way is difficult to survive due to the large slope and poor water retention property of the slope. And the fretwork effect of current frame bank protection has following problem: the hollowed-out area is small, the whole weight of the block is large, and materials are wasted; if the aperture is simply enlarged, filling gravels or planting soil in the frame can be caused to run off from the hollowed-out points, the hollowed-out area is large, the stress of the structure is unbalanced, and the structure is easy to be damaged.
