Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a reinforced concrete slope retaining wall building block. Background Art

[0002] At present, most of the river slope retaining walls and mountain slope retaining walls are made of rubble blocks and traditional concrete blocks. These blocks need to be built with cement mortar, which is labor-intensive, time-consuming, inefficient, costly, and the overall mechanical properties of the slope retaining walls after construction are not good. In order to overcome the above problems, in the technical field of using concrete blocks to build slope retaining walls, a reinforced concrete slope retaining wall block is needed.

[0003] The slope of the slope retaining wall blocks commonly used at present needs to be manually controlled when laying the upper and lower layers, which makes the construction relatively difficult and can often only achieve flat or single-directional slope retaining walls. When it is necessary to set up a curved slope retaining wall, cement covering and bonding are required, which makes the operation difficult, the workload is large, and the limitations are large. Utility Model Content

[0004] The utility model aims to provide a reinforced concrete slope retaining wall block to solve the above-mentioned background technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforced concrete slope protection retaining wall block, comprising: a retaining wall slope protection block body, cavities are opened on the left and right sides of the top of the retaining wall slope protection block body, transverse through holes are opened on the left and right sides of the retaining wall slope protection block body, the front side of the retaining wall slope protection block body is fixedly connected to the limited displacement platform, and a steel cage is arranged in the retaining wall slope protection block body;

[0006] The connecting assembly comprises screw rods inserted into adjacent side transverse through holes on two adjacent retaining wall slope protection blocks, and nuts are threadedly connected to the outer sides of both ends of the screw rods.

[0007] Preferably, the top-view cross-section of the retaining wall slope protection block body is an isosceles trapezoid, and the top-view cross-section of the cavity is a right-angled trapezoid.

[0008] Preferably, the height of the limiting offset platform is higher than the height of the retaining wall slope protection block body.

[0009] Preferably, trapezoidal grooves are provided at equal intervals on the top of the limiting offset platform, and bevel angles are provided on the left and right end surfaces of the limiting offset platform.

[0010] Preferably, the inner side of the cavity is filled with crushed stones.

[0011] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0012] 1. There are cavities on the left and right sides of the retaining wall and slope protection blocks. The cavities are filled with crushed stones to increase the weight of the wall and increase the friction and shear resistance between the blocks;

[0013] 2. The ribs on the left and right sides are provided with symmetrical transverse perforations, and the retaining wall blocks in the same row are connected to each other transversely with rust-proof screws to form a whole, with high overall stability;

[0014] 3. When paving the upper and lower layers of blocks, you can lay them in an I-shaped pattern to increase the friction between the blocks;

[0015] 4. Both the upper and lower layers have limited displacement. On the one hand, the lower block is guaranteed to be displaced, and the upper block is pushed back to prevent the upper block from tipping forward, and so on. This increases the wall's anti-overturning and anti-creep forces.

[0016] 5. When the slope retaining wall is to be curved or arc-shaped, the maximum inner arc between the two blocks can be 30 degrees or 120 degrees, meeting the requirements for designing arc-shaped slope retaining walls. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 The reinforced concrete slope protection retaining wall block shown in the figure comprises: a retaining wall slope protection block body 1, cavities 2 are opened on the left and right sides of the top of the retaining wall slope protection block body 1, transverse through holes 3 are opened on the left and right sides of the retaining wall slope protection block body 1, the front side of the retaining wall slope protection block body 1 is fixedly connected to a limited displacement platform 4, and a steel cage 10 is arranged in the retaining wall slope protection block body 1; a connecting component, the connecting component comprises a screw rod 5 inserted into the adjacent side transverse through holes 3 on two adjacent retaining wall slope protection block bodies 1, nuts 6 are connected to the outer sides of the two ends of the screw rod 5 with threads, and symmetrical transverse through holes 3 can be provided to connect the retaining wall slope protection block bodies 1 located in the same row horizontally with the screw rod 5 with rust-proof ability as a whole, the overall stability is high, and when the upper and lower layers of blocks are paved, I-shaped paving can be carried out. To increase the friction between the blocks; on the other hand, for each 35 cm high layer installed, the upper layer as a whole retreats 12 to 18 cm behind the wall to save land, and the cavity 2 also serves the function of planting greenery; according to design requirements, for each one or two layers of blocks installed, a 4-5 meter long continuous longitudinal plastic geogrid is laid behind the wall, and the blocks press the geogrid so that the compacted soil behind the wall of the slope retaining wall is connected to the wall through the geogrid to form a whole, thereby increasing the anti-slip and anti-overturning force of the entire wall, thereby increasing the stability of the slope retaining wall; and when the slope retaining wall surface is to realize a curved or arc-shaped slope retaining wall, the maximum inner arc between the two blocks can be 30 degrees or 120 degrees, which meets the requirements of the design of the arc-shaped slope retaining wall, and the steel cage is used to increase the shear and tensile resistance of the blocks.

[0026] Furthermore, the top-view cross-section of the retaining wall slope protection block body 1 is an isosceles trapezoid, and the top-view cross-section of the cavity 2 is a right-angled trapezoid. The trapezoidal structure can facilitate the realization of a curved retaining wall structure to improve the adaptability of the block.

[0027] Furthermore, the height of the limit staggered platform 4 is higher than the height of the retaining wall slope protection block body 1. By arranging the limit staggered platform 4 on both the upper and lower layers, on the one hand, the lower block is staggered, and the upper block is retreated 12 to 18 cm to prevent the upper block from overturning forward, and so on, thereby increasing the wall's anti-overturning force and anti-creep force.

[0028] Furthermore, trapezoidal grooves 7 are provided at equal intervals on the top of the limiting offset platform 4, and bevel angles 8 are provided on the left and right end surfaces of the limiting offset platform 4.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
