Description

Technical Field

[0001] The present invention relates to a beach protection structure, in particular to a B-shaped ecological beach protection block and a beach protection structure using the block. Background Art

[0002] At present, the water transportation industry is facing the transition from engineering water transportation to green water transportation. Under this background, the construction of ecological waterways has gradually become the development trend of future inland waterway construction in China, and it is also an important countermeasure to coordinate shipping development and river ecological protection and achieve the sustainable development of waterway construction. In waterway regulation projects, traditional beach protection projects mostly adopt rigid structures. Although they have strong safety and durability, they will separate the river and the shore ecosystem, hinder the exchange of material fluxes, reduce the diversity of water flow patterns, and to a certain extent affect the shore zone ecology and the habitat environment of aquatic organisms. Seriously, it will even have a negative impact on the stable development of the river ecosystem and the natural environment. Therefore, it is necessary to further develop new ecological beach protection structures that can take into account ecological and environmental benefits and other benefits while meeting the engineering stability and safety. Summary of the Invention

[0003] The present invention provides a B-shaped ecological beach protection block and a beach protection structure using the block to solve the technical problems existing in the known technology. The river beach protection structure formed by using the beach protection block not only has good beach protection engineering effects, but also can fully reflect ecological and environmental protection values.

[0004] One technical solution adopted by the present invention to solve the technical problems existing in the known technology is: a B-shaped ecological beach protection block, including a horizontally placed B-shaped main body. The bottom of the main body is a rectangular bottom plate, and the upper part is a semi-circular arch located on one side of the rectangular bottom plate and extending along the entire width of the rectangular bottom plate. Two transverse tenons are provided on the front side of the rectangular bottom plate, and two transverse mortises corresponding to and adapted to the transverse tenons are provided on the rear side. A longitudinal tenon is provided on the left side of the rectangular bottom plate, and a longitudinal mortise adapted to the longitudinal tenon is provided on the right side. Two holes are provided on the rectangular bottom plate, and the two holes are respectively located inside and outside the semi-circular arch.

[0005] The cross-section of the hole is square.

[0006] The length of the rectangular bottom plate is 2 times its width, and the thickness is 0.1 - 0.15 times its width.

[0007] The diameter of the semi-circular arch is 0.5 times the length of the rectangular bottom plate, the width is the same as the width of the rectangular bottom plate, and the thickness is 0.1 - 0.15 times the width of the rectangular bottom plate.

[0008] The length of the transverse tenon and the transverse mortise is 0.15 - 0.2 times the length of the rectangular bottom plate, the width is 0.1 - 0.15 times the width of the rectangular bottom plate, and the height is the same as the thickness of the rectangular bottom plate.

[0009] The length of the longitudinal tenon and the longitudinal mortise is 0.05 - 0.075 times the length of the rectangular bottom plate, the width is 0.3 - 0.4 times the width of the rectangular bottom plate, and the height is the same as the thickness of the rectangular bottom plate.

[0010] The side length of the square hole is 0.3 - 0.4 times the width of the rectangular bottom plate.

[0011] Another technical solution adopted by the present invention to solve the technical problems existing in the prior art is: a beach protection structure using the above-mentioned b-shaped ecological beach protection block. The beach protection structure is formed by splicing the beach protection blocks. The length direction of the beach protection blocks is arranged along the river bank or the water flow direction, and a gravel structure is filled in the holes.

[0012] The semi-circular arches of two adjacent beach protection blocks in the transverse direction are coaxially arranged or staggered.

[0013] The advantages and positive effects of the present invention are: 1) The block size is unified, and modular production can be carried out. 2) Made of concrete, it has good safety and durability and does not require later maintenance. 3) It is convenient to splice and lay on site, and the construction efficiency is high; there is no need to use cement mortar for masonry, saving project costs. 4) Tenons and grooves are provided on each side of the block, which can be spliced in different ways according to actual situations, and at the same time, the stability of the overall beach protection structure can be increased. 5) The semi-circular arch structure is beautiful in appearance. The beach protection structure formed after splicing can reduce the energy of water flow and wave flow, and increase the diversity of water flow patterns. The inside of the arch can provide a habitat space and passage for aquatic organisms, creating a favorable living environment. 6) The block is provided with holes, which can ensure the lateral connectivity between the river channel water body and the bank slope.

[0014] In summary, while playing the traditional beach protection function, the present invention can create a suitable habitat for the survival of aquatic organisms and has good ecological benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A more detailed description is as follows:

[0027] For the convenience of description, define the straight line direction where the long side of the rectangular bottom plate is located as the x direction, the straight line direction where the short side is located as the y direction, and the normal direction of the rectangular bottom plate as the z direction. On both sides of the rectangular bottom plate in the y direction, there are two pairs of transverse tenons 2, 3 and transverse mortises 4, 5 with the same position and size.
