Description

Technical Field

[0001] The utility model relates to the field of slope protection, in particular to a slope protection component. Background Art

[0002] For the fill subgrade slope on the road, the slope ratio is generally not steeper than 1:1.5, except for the case of manually laying stones. The cut slope ratio is generally determined according to the geological conditions. For soil or fully weathered and strongly weathered slopes, the slope should not be steeper than 1:1.5 (about 33.69°).

[0003] Common slope protection forms for highway slopes are as follows: 1. Arch-shaped frame slope protection, where the arch frame forms a chute to lead rainwater from the upper part to the low-lying area, and grass is planted inside the arch for slope protection and environmental beautification; 2. Hollow hexagonal block slope protection, with grass planted in the holes.

[0004] In the arch frame slope protection, the soil inside the arch frame has no shelter and is easily washed away by rainwater, resulting in slope collapse and damage to the arch frame, and the original drainage function will be lost. In the hollow hexagonal block slope protection, the blocks are laid obliquely according to the slope, and the soil inside the holes is easily washed out by rainwater, forming cavities under the blocks, leading to slope settlement.

[0005] Soil erosion on slopes is one of the main factors causing slope collapse and instability. How to prevent the erosion of shallow soil layers, green and solidify the soil, and prevent slope collapse on roads is an urgent matter at present.

[0006] In the process of implementing the present utility model, the inventor found that: soil erosion on slopes is mainly related to soil erosion prevention, greening, and drainage, and is the result of the comprehensive combination of these technical elements. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a slope protection component, which can achieve the result of preventing soil erosion on slopes through the reasonable combination of functions such as erosion prevention, greening, and drainage.

[0008] To this end, the present utility model provides a slope protection component, including blocks and clamping blocks. The block is of an L-shaped structure, including a step riser and a step tread. The step riser is a soil retaining member, and the step tread is a horizontal member. Lock tooth assemblies are symmetrically arranged on the left and right sides of the block. Lock grooves are symmetrically arranged on the left and right sides of the clamping block. The lock tooth assembly includes a riser side lock tooth located on the side of the step riser and a tread side lock tooth located in front of the step tread. Among them, when the slope protection component is used for slope protection, the upper block is longitudinally aligned with the lower block, the step tread of the upper block is placed on the step riser of the lower block, the tread side lock tooth and the riser side lock tooth are stacked up and down, and are inserted and matched with the lock groove of the clamping block to form a blocking and locking structure.

[0009] Furthermore, the above-mentioned locking groove is a dovetail groove, and the corresponding step-side locking teeth and riser-side locking teeth are dovetail teeth or their modified structures. The locking groove extends in the height direction of the clamping block. When laying the slope protection, the clamping block is installed from top to bottom along the locking teeth, and forms locking structures with the step-side locking teeth and the riser-side locking teeth respectively, so that the clamping block clamps and fixes the upper and lower layers of building blocks.

[0010] Furthermore, the above-mentioned riser-side locking teeth are of the same height as the step riser, and the step-side locking teeth are of the same thickness as the step tread. The dovetail teeth include a tooth body part, a front tooth tip protruding from the tooth body part, and a rear tooth tip protruding from the tooth body part. The modified structure of the dovetail teeth includes a tooth body part and a front tooth tip or a rear tooth tip integrally formed with the tooth body part.

[0011] Furthermore, the locking groove of the above-mentioned clamping block is a rectangular groove, and the riser-side locking teeth and step-side locking teeth of the building block are both straight teeth.

[0012] Furthermore, when laying the slope protection with the above-mentioned slope protection components, the clamping blocks are laid along the slope direction. The thickness and length of the clamping blocks satisfy one of three states, and adjacent two clamping blocks form a butt joint or a lap joint or a state of maintaining a gap.

[0013] Furthermore, the bottom surface of the above-mentioned clamping block is supported on the soil body, or on the step tread of the lower building block, or on the top surface of the lower clamping block. After the clamping block is well supported, the thickness of the clamping block should be higher than the riser-side locking teeth, and satisfy that part or all of the thickness of the superimposed step-side locking teeth is embedded in the locking groove.

[0014] Furthermore, the locking grooves symmetrically arranged on the left and right sides of the above-mentioned clamping block divide the clamping block into three parts: a front part, a middle part, and a rear part. Among them, the part between the two locking grooves is the middle part, and the width of the front part is greater than the width of the rear part. When laying, the two sides of the front part of the clamping block can be supported on the step tread of the lower building block, and the clamping block will not move down along the locking teeth.

[0015] Furthermore, the above-mentioned step tread is a hollow horizontal member with one or more grass-planting cavities penetrating up and down; or the step tread is a solid horizontal member for pedestrians to pass.

[0016] Furthermore, the top surface and the bottom surface of the above-mentioned clamping block are both horizontal planes; or the top surface of the clamping block is an inclined plane and the bottom surface is a horizontal plane; or the top surface and the bottom surface of the clamping block are both inclined planes.

[0017] Furthermore, a drainage groove along the slope direction is provided in the middle of the top surface of the above-mentioned clamping block.

[0018] Compared with the existing stepped blocks, the slope protection component of the present utility model includes blocks and clamping blocks. The blocks are in an L-shaped structure, capable of realizing functions of preventing erosion and greening. The clamping blocks can realize drainage. When laying the slope protection, the clamping blocks can lock the upper and lower layers of blocks to form a stable stepped structure, thus realizing a reasonable combination of functions such as preventing erosion, greening, and drainage, and achieving the effect of preventing soil erosion on the slope.

[0019] In addition, as the smallest stepped unit, the step of the block can be a hollow horizontal member, and at this time, a very high (more than 80%) greening ratio can be achieved. The step can also be a solid horizontal member, thereby realizing the effect of allowing pedestrians to pass.

[0020] In addition to the purposes, features, and advantages described above, the present utility model has other purposes, features, and advantages. The following will refer to the drawings to further describe the present utility model in detail. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0055] Embodiment 1

[0056] Combined with reference Figures 1 to 7 The slope protection assembly of this embodiment includes a building block 10 and a clamping block 20.

[0057] The block 10 is an L-shaped structure, comprising a step plate 11 and a step tread 12, and is an integrally formed concrete product. The step plate is a retaining member, and the step tread is a hollow horizontal member. The left and right sides of the block are symmetrically provided with locking tooth components.

[0058] The locking tooth assembly comprises locking teeth 13 on the side of the step uprights and locking teeth 14 on the side of the step treads arranged forward on both sides of the step uprights.

[0059] A drainage groove 21 is provided on the top surface of the clamping block 20 , and locking grooves 22 are symmetrically provided on the left and right sides thereof.

[0060] In this embodiment, the locking groove 22 is a dovetail groove. Correspondingly, the vertical plate side locking teeth 13 and the step side locking teeth 14 are adapted to cooperate with the dovetail groove 21 and can be dovetail teeth or a modified structure of dovetail teeth. In other embodiments, the locking groove 22 can be a deformed structure of the dovetail groove, such as a T-shaped groove.

[0061] The vertical plate side locking teeth 13 extend along the height direction of the building block, and the step side locking teeth 14 also extend along the height direction of the building block.

[0062] When laying the slope protection, the upper building blocks and the lower building blocks are longitudinally aligned and arranged in columns. The step treads 12 of the upper building blocks are placed on the step risers 11 of the lower building blocks. The step side locking teeth 14 of the upper building blocks and the vertical plate side locking teeth 13 of the lower building blocks are stacked up and down. The clamping blocks are installed from top to bottom along the locking teeth. The locking grooves of the clamping blocks are inserted and matched with the step side locking teeth 14 and the vertical plate side locking teeth respectively to form locking structures for clamping and fixing the upper and lower layers of building blocks.

[0063] In addition, the clamping blocks are laid along the slope direction and the upper and lower clamping blocks are abutted together.

[0064] In the present utility model, there are several types of clamping blocks to choose from:

[0065] 1. As shown in Figure 3 , the top surface 201 of the clamping block 20 is parallel to the bottom surface 202. When laying the slope protection, the clamping block is placed obliquely, and its orientation is consistent with the slope direction. The upper and lower clamping blocks are abutted together, and the lower port of the drainage groove of the upper clamping block is connected to the upper port of the drainage groove of the lower clamping block;

[0066] 2. As shown in Figure 4 , the bottom surface 202 of the clamping block 20 is a horizontal plane, and the top surface 201 is an inclined plane. When laying the slope protection, the clamping block is placed horizontally. The upper and lower clamping blocks are abutted together. There is a height difference in the height direction between the lower port of the drainage groove of the upper clamping block and the upper port of the drainage groove of the lower clamping block, and the height of the lower port of the upper clamping block is not lower than the height of the upper port of the lower clamping block;

[0067] 3. As shown in Figure 5 , the bottom surface 202 of the clamping block 20 is a horizontal plane, and the top surface 201 is an inclined plane. There is an upper overlapping edge 23 on the lower side of the clamping block. When laying on the slope, it is placed horizontally. The upper and lower clamping blocks are abutted together, and the upper overlapping edge 23 overlaps on the top of the lower clamping block. The lower port of the drainage groove of the upper clamping block intersects with the upper port of the drainage groove of the lower clamping block and there is a height difference in the height direction.

[0068] In the slope protection system, the clamping blocks in the same column adopt the same configuration, and the clamping blocks in different columns can adopt different configurations.

[0069] In this embodiment, the clamping block 20 is provided with a rope-passing hole 24. The clamping blocks in the same column are connected together by threading a whole steel wire rope 40, which further strengthens the fixation of the slope protection.

[0070] Since the step tread is a hollow horizontal member, the formed horizontal grass-planting cavity 12a can retain water and soil. In the existing hollow hexagonal blocks, the soil in the hexagonal holes is inclined and prone to loss. In contrast, in this embodiment, the border of the hollow horizontal member of the step tread forms ridges, similar to the principle of terraced fields, which can prevent the soil in the frame from being washed away. At the same time, drainage channels are formed by the clamping blocks on the left and right sides of the steps, which can lead the rainwater on the slope from a high place to a low place.

[0071] Compared with the existing green slope protection blocks, the hollow horizontal member of this embodiment can have a very high greening ratio (up to 80%), while preventing the soil from being washed away. The blocks are clamped and locked by the clamping blocks to avoid loosening, and can drain water smoothly during heavy rainfall, achieving an ideal green slope protection effect.

[0072] Embodiment Two

[0073] As Figure 8 shown, compared with the first embodiment, the front side wall 121 of the step tread 12 of the block in this embodiment protrudes outward in an arc shape, and the front wall surface 11a of the step riser 11 also protrudes outward in an arc shape.

[0074] Embodiment Three

[0075] As Figure 9 and Figure 10 shown, the step tread 12 of the block in this embodiment is a solid horizontal member, which can be used for pedestrians to go up and down the slope.

[0076] In the slope protection system, there may be situations where pedestrians go up and down the slope. At this time, the blocks with solid horizontal step treads can form a row of steps or multiple rows of steps.

[0077] In this embodiment, the pedestrian passage and greening are combined to achieve the balance of the functions of passage and greening.

[0078] Embodiment Four

[0079] As Figure 11 and Figure 12 shown, in this embodiment, the locking groove of the clamping block is a dovetail groove.

[0080] The top surface 221 of the clamping block is a plane, which is flush with the side top surface of the step tread. The drainage groove 21 is arranged in the middle of the top of the clamping block 20 and extends downward obliquely.

[0081] The clamping block 20 is divided into three parts: a front part 20a, a middle part 20b, and a rear part 20c by locking grooves symmetrically arranged on the left and right sides of the clamping block. Among them, the part between the two locking grooves 22 is the middle part 20b, the rear part 20c separates two adjacent blocks on the left and right, the width W1 of the front part 20a is greater than the width W2 of the rear part 20c. During laying, both sides of the front part 20a of the clamping block can be supported on the step treads 12 of the lower block and will not slide downward along the locking teeth.

[0082] The thickness and length of the clamping block are designed to meet the requirement that the upper clamping block can overlap on the lower clamping block.

[0083] Embodiment 5

[0084] As Figure 13 and Figure 14 shown, in this embodiment, the bottom surface 202 of the clamping block is a plane, the top surface of the clamping block is an inclined plane extending along the slope direction, a drainage groove is arranged in the middle of the top surface of the clamping block. The clamping block is composed of a front part 20a, a middle part 20b, and a rear part 20c. The front part 20a is supported on the step treads of the lower block, and the upper and lower clamping blocks are in contact with each other. The drainage grooves of the upper and lower clamping blocks form a continuous drainage groove structure without a drop.

[0085] Embodiment 6

[0086] As Figures 15 to 18 shown, in this embodiment, the top surface of the clamping block is a plane and no drainage groove is provided. In the following embodiments, no drainage groove is provided on the top surface of the clamping block either.

[0087] The side locking teeth of the vertical plate of the clamping block are a modified structure of dovetail teeth, in which the tooth shape part that does not exceed the front wall surface of the vertical plate is retained, and the part that exceeds is removed and not retained.

[0088] The step tread is a hollow horizontal component, including outer retaining walls arranged in parallel at intervals with the step vertical plate and several spaced ridges located between the step vertical plate and the outer retaining walls. The top surfaces of the several spaced ridges are flush and the height is lower than the top surface of the outer retaining wall, forming a plurality of horizontal grass planting cavities. When filling the matrix or soil in the horizontal grass planting cavities, the top surface of the matrix / soil is flush with the top surface of the spaced ridges, and in this way, the growing green plants can easily cover the spaced ridges.

[0089] Several longitudinally extending spaced ridges can increase the structural strength of the step tread, enabling the step tread to be made long enough, such as 1 meter - 1.2 meters.

[0090] Embodiment 7

[0091] As Figure 17 and Figure 18 shown, in this embodiment, the clamping block 20 is supported on the soil body and is flush with the soil body at the bottom surface of the step tread. In addition, a gap state is maintained between two adjacent clamping blocks.

[0092] The clamping block is a dovetail groove, and both the vertical plate side locking teeth and the step side locking teeth are dovetail teeth that match the dovetail groove.

[0093] Example Eight

[0094] As Figures 19 to 21 shown, in this embodiment, the clamping block 20 is divided into three parts: a front part 20a, a middle part 20b, and a rear part 20c by locking grooves 22 symmetrically arranged on the left and right sides. Among them, the part between the two locking grooves 22 is the middle part 20b, and the width of the front part 20a is greater than the width of the rear part 20c. When laying, the two sides of the front part of the clamping block can support on the step treads of the lower-layer building blocks and will not slide down along the locking teeth.

[0095] Both the vertical plate side locking teeth 13 and the step side locking teeth 14 are dovetail teeth that match the dovetail groove.

[0096] Example Nine

[0097] As Figure 22 shown, the thickness and length of the clamping block satisfy that adjacent two clamping blocks form an overlap. That is, the length of the clamping block in the front-rear direction is relatively long, and the front end of the upper clamping block supports on the top surface of the lower clamping block.

[0098] Example Ten

[0099] As Figure 23 shown, in this embodiment, the locking groove 22 of the clamping block is a rectangular groove, and both the vertical plate side locking teeth 13 and the step side locking teeth 14 of the building block are straight teeth. The two are of the same width as the rectangular groove.

[0100] Among them, the vertical plate side locking teeth are composed of the part where the step vertical plate extends outward relative to the step tread, and the step side locking teeth are composed of the part where the outer frame wall of the step tread extends outward relative to the left and right frame walls.

[0101] The locking groove can also be a deformed groove of the rectangular groove, such as a trapezoidal groove.

[0102] Example Eleven

[0103] As Figure 24 shown, in this embodiment, the locking groove of the clamping block is a rectangular groove, and the clamping block 20 is divided into three parts: a front part 20a, a middle part 20b, and a rear part 20c by locking grooves 22 symmetrically arranged on the left and right sides. Among them, the part between the two locking grooves 22 is the middle part 20b, and the width of the front part 20a is greater than the width of the rear part 20c. When laying, the two sides of the front part 20a of the clamping block 20 can support on the step treads of the lower-layer building blocks, so that the clamping block will not slide down along the locking teeth.

[0104] Example Twelve

[0105] As Figures 25 to 32As shown in the figure, this embodiment shows various structural variants of the vertical side locking teeth 13 and the step side locking teeth 14 of the building block when the locking groove 22 is a dovetail groove. When the vertical side locking teeth 13 are dovetail teeth, the structure of the dovetail teeth can be regarded as consisting of three parts, namely, the tooth body part 131, the front tooth tip 132 protruding from the tooth body part, and the rear tooth tip 133 protruding from the tooth body part. Similarly, when the step side locking teeth 14 are dovetail teeth, the structure of the dovetail teeth can be regarded as consisting of three parts, namely, the tooth body part 141, the front tooth tip 142 protruding from the tooth body part, and the rear tooth tip 143 protruding from the tooth body part.

[0106] As a modified variant of the dovetail teeth, the front tooth tip is retained and the rear tooth tip is removed, which is denoted as the front half locking teeth. As another modified variant of the dovetail teeth, the rear tooth tip is retained and the front tooth tip is removed, which is denoted as the rear half locking teeth. And the tooth body part, the front tooth tip and the rear tooth tip of the unmodified dovetail teeth are all included, which is denoted as the full teeth. The selection of the modified structure of the locking teeth is for additional considerations, such as reducing the difficulty of molding the building block by pressing, protecting the tooth tips from being knocked and damaged, and facilitating construction. In addition, for the convenience of the machine molding process, additional process structures can also be arranged on the building block.

[0107] In Figure 25 , the vertical side locking teeth of the building block are full teeth, and the step side locking teeth are the front half locking teeth. In Figure 26 , the vertical side locking teeth of the building block are full teeth, and the step side locking teeth are the rear half locking teeth.

[0108] In Figure 27 , the vertical side locking teeth of the building block are the rear half locking teeth, and the step side locking teeth are the front half locking teeth. In Figure 28 , the vertical side locking teeth of the building block are the front half locking teeth, and the step side locking teeth are the rear half locking teeth.

[0109] In Figure 29 , the step side locking teeth of the building block are full teeth, and the vertical side locking teeth are the front half locking teeth. In Figure 30 , the step side locking teeth are full teeth, and the vertical side locking teeth of the building block are the rear half locking teeth.

[0110] In Figure 31 , both the step side locking teeth and the vertical side locking teeth are the rear half locking teeth. In Figure 32 , both the step side locking teeth and the vertical side locking teeth are the front half locking teeth.

[0111] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
