Description

Technical Field

[0001] The utility model relates to the field of urban inner river slope protection, in particular to mortise and tenon assembled concrete slope protection blocks and slope protection. Background Art

[0002] The protection of the slopes of small and medium-sized inland rivers in cities needs to effectively prevent soil erosion, protect the environment and ensure the overall stability in later use. The traditional cast-in-place concrete slope protection has problems such as cumbersome construction, high energy consumption, and high carbon emissions. At present, the promotion of green and low-carbon building materials and green construction methods has developed prefabricated buildings, modular production, on-site assembly and construction, which are convenient and fast. The design of small and medium-sized river slope protection can also be used as a reference. The modular prefabricated slope protection needs to have strong soil retention and anti-scouring properties, and can have a good wave elimination and diversion effect. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model provides assembled concrete slope protection blocks and slope protection with mortise and tenon joints. The blocks are produced in batches in modular factories, and on-site assembly and construction are convenient and quick. The mortise and tenon joints of adjacent blocks are connected to achieve all-round self-locking up and down and left and right, forming a stepped slope surface slope protection with strong overall soil retention and anti-impact performance. The damage of a single block has little impact on adjacent blocks, and it is organically integrated with the environment to form an ecological system.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The mortise and tenon assembled concrete slope protection blocks include a rear wall and a front guard block. The width of the front guard block is smaller than the width of the rear wall and is located in the middle of the width of the rear wall. A concave groove is provided on one side of the edge flanges of the rear walls on the left and right sides of the front guard block, and a convex platform is provided on the other side of the edge flange. The convex platform and the concave groove are used for matching mortise and tenon connection of the left and right adjacent blocks. A planting groove is provided on the top surface of the front guard block, and a convex platform is provided on the top surface of the rear wall of the planting groove. A concave groove is provided on the front front of the bottom of the front guard block. The convex platform and the concave groove are used for matching mortise and tenon connection of the upper and lower blocks. A vertical groove is provided on the front side surface of the front guard block.

[0006] A further improvement is that the left and right corners of the front side of the front guard block are arc surfaces, so as to reduce the impact of water flow on the blocks.

[0007] A further improvement is that vertical grooves are also provided on the arc surface.

[0008] A further improvement is that two convex engaging platforms 2 are arranged at intervals on the left and right sides of the top surface of the rear wall of the planting trough, and two concave connecting grooves 2 are arranged at corresponding positions on the bottom surface of the front guard block.

[0009] A further improvement is that the building blocks are injection molded using a reinforced concrete structure.

[0010] The technical solution for achieving another object of the present invention is a mortise and tenon assembled concrete slope protection block slope protection, which is assembled using the blocks, with blocks on the same layer arranged side by side, convex platform one and concave joint groove one on the front and rear walls of the edge ridges of adjacent blocks connected by mortise and tenon joints, upper and lower layer blocks arranged front and back in a staggered manner, concave joint groove two of the upper layer blocks connected by mortise and tenon joints with convex platform two of the lower layer blocks to form a stepped slope surface, and the interval formed by the rear wall edge ridges between the left and right adjacent blocks constitutes a longitudinal drainage ditch. Beneficial Effects

[0011] 1. The second concave joint groove at the bottom of the upper and lower layers of the block body is assembled with embedded mortise and tenon joints with the second convex card platform at the top, and they are stacked and embedded layer by layer; the first concave joint groove on the rear wall of the left and right blocks of the same layer is assembled with embedded mortise and tenon joints with the adjacent convex card platform, so as to achieve all-round self-locking up and down and left and right, and the overall impact resistance is strong; the planting groove on the top surface of the block body is filled with soil, and plant species suitable for local growth and beneficial to beach consolidation are sown, which is organically combined with the environment to form an ecological system.

[0012] 2. The vertical groove design on the front side of the block body has a wave-breaking function, which slows down the flow of the river and diverts rainwater to irrigate the planting troughs; the underwater part can be used as a refuge and habitat for aquatic organisms such as fish; the longitudinal drainage ditch formed between adjacent blocks can reduce the erosion of the slope by rainwater.

[0013] 3. Because the blocks are prefabricated, they can be directly installed on site after being processed in the factory, eliminating the need for on-site foundation pouring, hoisting, installation work and unnecessary labor. The construction is convenient, and the breakage rate during construction is low, resource waste is minimized, which greatly reduces energy and resource consumption in the construction process and reduces construction pollution. The blocks are eco-friendly and recyclable.

[0014] 4. The flexible installation method allows it to have a certain movable space, which can offset the lateral pressure of the soil behind it; the self-embedded design reduces the bearing requirements on the foundation; the stones and soil filled inside can improve the ability of the slope protection to resist horizontal shear force.
