Description

Technical Field

[0001] The utility model belongs to the technical field of river embankments, and particularly relates to a multi-slope adjustable self-nesting slope protection for river ecological environment management. Background Art

[0002] Traditional river channel slope protection masonry is mostly hoisted by large machinery with manual assistance and limited adjustment. The masonry is reinforced by bolt connection. The bolt reinforcement method has high requirements on the straightness of the masonry. The connection process requires continuous debugging, which is time-consuming and labor-intensive. The bolt connection parts are susceptible to external corrosion, slippage and displacement. The process is complicated, the construction cost is high, and it is not convenient for later maintenance. In addition, during the installation of traditional river channel masonry, when encountering a multi-slope river channel, it is necessary to manually adjust the appropriate slope before installation, which cannot meet the requirements of multi-slope river channels. Summary of the invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a multi-slope adjustable self-nested slope protection for river ecological environment management.

[0004] The present invention is achieved through the following technical solutions:

[0005] The multi-slope adjustable self-nested slope protection for river ecological environment management includes a rectangular block, an opening is provided on the top of the block, a plurality of limiting grooves are symmetrically provided on the left and right sides of the top surface of the block along the width direction of the block, and a protrusion matching the limiting grooves is provided downward on the left and right sides of the bottom surface of the block; lifting holes are symmetrically provided on the left and right sides of the block, a plurality of water outlets are provided on the bottom surface of the block, and an overflow outlet is provided on the front side of the block.

[0006] Preferably, the overflow outlet is provided with two upper and lower ones.

[0007] Preferably, the building blocks are concrete building blocks.

[0008] The slope protection structure of the present invention is simple, and the masonry can be nested in suitable limiting grooves according to different slopes, which not only avoids the time-consuming and labor-intensive traditional masonry bolt connection, the risk of slippage and displacement due to external corrosion, and the like, but also can reduce the slope adjustment and save construction costs; the single slope protection masonry of the present invention is easy to dismantle, and later renovation, dismantling or recycling is relatively convenient; when the water level of the slope protection masonry of the present invention is high, the accumulated water can flow out from the overflow port, and the anti-overturning performance is good. Planting plants inside can make the connection between the masonry and the soil foundation more stable, improve the pull-out resistance of the masonry, and be beneficial to the water and soil conservation of the river slope protection.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0015] This embodiment includes a block 2, preferably a concrete block, which is prefabricated in the factory in advance. The block 2 is in the shape of a rectangular parallelepiped, with an opening on the top of the block 2, and a plurality of position-limiting grooves 3 are symmetrically arranged on the left and right sides of the top surface of the block 2, and the position-limiting grooves 3 are distributed along the width direction of the block 2. A protrusion 4 matching the position-limiting groove 3 is arranged downward on the left and right sides of the bottom surface of the block 2, and the protrusion 4 can be inserted into the position-limiting groove 3 to realize the connection between the upper and lower blocks 2, avoiding the time-consuming and labor-intensive traditional bolt connection. In order to facilitate the mobile installation of the block 2, hoisting holes 5 are symmetrically arranged on the left and right sides of the block 2, and the block 2 can be hoisted by a small machine or manually.

[0016] A plurality of water outlets 6 are provided on the bottom surface of the block 2, and an overflow outlet 7 is provided on the front side of the block 2. In this embodiment, two overflow outlets 7 are provided, one above the other. When the water level in the block 2 is high, the accumulated water inside can flow out from the overflow outlet 7, and the anti-overturning performance is good. Gravel, soil or vegetation bags can be laid in the block 2 to plant plants. The plant roots can take root from the water outlet 6 at the bottom of the block 2, and are connected to the soil base 1 below the block 2 through the water outlet 6, which not only realizes ecological slope protection, but also improves the pull-out resistance of the block 2, which is beneficial to the water and soil conservation of the river slope.

[0017] During construction, select the limiting groove 3 for the upper and lower blocks 2 to be connected with the protrusion 4 according to the designed slope, then construct the stepped soil foundation 1 according to the position of the limiting groove 3 connected to the block 2, lay gravel, soil, etc. in the block 2, plant the plants, and then hoist the block 2 to be placed on the lowest soil foundation 1. The bottom of the lowest block 2 may not have a protrusion 4, or the protrusion 4 may be directly buried in the soil foundation 1, and then the blocks 2 are clamped upward in sequence to form a stepped block 2 that matches the soil foundation 1. When the slope is gentle, the protrusion 4 of the block 2 is clamped into the limiting groove 3 that is relatively backward of the block 2, as shown in the attached Figure 1 When the slope is steeper, the protrusion 4 of the block 2 is inserted into the limiting groove 3 near the front, as shown in the attached Figure 2After the blocks 2 are stacked and installed one by one, the gaps between the blocks 2 are filled with soil.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
