Highway revetment concrete block

Abstract

This utility model discloses a concrete block for highway slope protection, comprising multiple blocks laid on the side slope of a highway. Each block has a groove at its top and bottom, with three fixing holes at the top of the groove. A long strip pad is placed inside the groove on top of each block, and three nail rods are driven through the long strip pad. This utility model uses the interlocking of the grooves and blocks to form a single unit. The long strip pad is then placed inside the groove, and the nail rods are driven through the long strip pad and fixing holes into the slope. Finally, angle steel is installed on the top and bottom blocks for support. This achieves the interlocking of the blocks to form a unified structure. Combined with the nail rods driven into the slope and the angle steel support, this creates a stable slope protection structure that effectively resists water erosion and soil pressure, improving its resistance to sliding and overturning.

Description

Technical Field

[0001] This utility model belongs to the field of highway slope protection technology, and in particular relates to concrete blocks for highway slope protection. Background Technology

[0002] To prevent damage such as peeling, crumbling, and erosion of embankment and cutting slopes caused by natural factors such as water, temperature, and wind, effective protective measures such as laying concrete blocks on highway slopes are required: to resist erosion and soil loss, prevent landslides and collapses, and distribute loads.

[0003] The stability of masonry slope protection largely depends on the overall flatness of the slope surface and the compaction of the foundation. If the foundation is not properly treated (such as insufficient compaction or uneven settlement), the upper masonry blocks are prone to local collapse, deformation, or slippage, leading to the failure of the entire slope protection system. To increase the stability of concrete blocks, we designed highway slope protection concrete blocks. The blocks interlock to form a whole, and with the nail rods driven into the slope surface and the support of angle steel, a stable slope protection structure is formed, effectively resisting water erosion and soil pressure, and improving the resistance to sliding and overturning. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a concrete block for highway slope protection, comprising multiple blocks laid on the side slope of a highway, each block having a groove at its top and bottom, three fixing holes at the top of the groove, a long strip pad placed on the top of the block within the groove, three nail rods (first type) passing through the long strip pad, the bottom of each nail rod passing through the fixing holes and embedded in the slope, angle steel installed above and below the slope, the sides of the angle steel abutting against the blocks, and two nail rods (second type) passing through the angle steel and embedded in the slope.

[0006] Preferably, the top and bottom of the nail rod are provided with planting grooves, and the block brick is provided with two symmetrical planting grooves.

[0007] Preferably, each side of the block brick is provided with two locking grooves, and each side of the block brick is provided with a locking block that matches the locking groove.

[0008] Preferably, the elongated pad has three through holes for the nail rod to pass through.

[0009] Preferably, the end of the nail rod located at the top of the brick block is spherical, and the diameter of the spherical end of the nail rod is larger than the diameter of the fixing hole.

[0010] The beneficial effects of this utility model are: This utility model utilizes the interlocking of locking grooves and locking blocks to form a whole from multiple brick blocks. A long strip of pad is then placed inside the groove. Next, a nail rod is inserted through the long strip of pad and through the fixing hole into the slope. Finally, angle steel is installed on the top and bottom brick blocks to provide support. This achieves the goal of interlocking the brick blocks to form a whole, combined with the nail rod inserted into the slope and the angle steel support, creating a stable slope protection structure that effectively resists water erosion and soil pressure, improving its resistance to sliding and overturning.

[0013] In the following description, embodiments of the concrete blocks for highway slope protection according to the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4This invention illustrates a concrete block for highway slope protection, comprising multiple blocks 1 laid on the side slope of a highway. Each block 1 has a strip groove 2 at its top and bottom. Each nail rod 7 has a planting groove 8 at its top and bottom. Two symmetrical planting grooves 9 are provided on each block 1. Three fixing holes 3 are provided at the top of the strip groove 2. A long strip pad 4 is placed on the top of each block 1, located within the cavity of the strip groove 2. Three nail rods 5 are threaded through the long strip pad 4. Three holes 3 are provided on the long strip pad 4 for... The nail rod 5 passes through the through hole 12. The end of the nail rod 5 at the top of the block brick 1 is spherical. The diameter of the spherical end of the nail rod 5 is larger than the diameter of the fixing hole 3. The bottom of the nail rod 5 passes through the inner cavity of the fixing hole 3 and is driven into the slope. Angle steel 6 is installed above and below the slope. The side of the angle steel 6 abuts against the block brick 1. The nail rod 7 is installed through the angle steel 6 and is driven into the slope. Two locking grooves 10 are provided on both sides of the block brick 1. Locking blocks 11 that are compatible with the locking grooves 10 are provided on both sides of the block brick 1.

[0015] Working principle: When using this utility model, the bottom angle steel 6 is fixed by nail rod 7 according to the measurement and layout. Then, the masonry bricks 1 are laid from the bottom up. According to the highest point of the masonry bricks 1, the top angle steel 6 is installed. The long strip pad 4 is placed in the inner cavity of the strip groove 2. Then, the nail rod 5 is picked up and passed through the through hole 12 on the long strip pad 4 and the fixing hole 3 on the strip groove 2. It is driven into the soil by hammering. Plants are sown in the inner cavity of planting trough 8 and planting trough 9 as needed to achieve ecological slope protection. The interlocking of multiple masonry bricks 1 forms an overall stable slope protection structure, which effectively resists water erosion and soil pressure, and improves the anti-sliding and anti-overturning ability.

[0016] In summary, this highway slope protection concrete block, through the interlocking of locking grooves 10 and locking blocks 11, allows multiple blocks 1 to form a whole. Then, a long strip 4 is placed in the inner cavity of the strip groove 2. Next, a nail rod 5 is passed through the long strip 4 and through the fixing hole 3 and driven into the slope surface. Finally, angle steel 6 is installed on the top and bottom blocks 1 respectively to achieve support. This achieves the goal of interlocking between the blocks to form a whole, and with the nail rod driven into the slope surface and the support of the angle steel, a stable slope protection structure is formed, which effectively resists water erosion and soil pressure, and improves the anti-slip and anti-overturning capabilities.
