Description

Technical Field

[0001] This utility model relates to the technical field of riverbank protection, and in particular to a slope protection block and slope protection structure. Background Technology

[0002] Slope protection blocks are block-shaped structures installed on earthen slopes or embankments near water bodies to prevent rockfalls on steep slopes and soil erosion on embankments.

[0003] To improve the installation stability of slope protection blocks, current methods often involve connecting adjacent blocks via side-mounted joints to form a slope protection structure that covers the entire slope. Examples include the interlocking slope protection block described in Chinese Patent Publication No. CN222575520U, and the improved slope protection block structure described in Chinese Patent Publication No. TW319259U. However, this method of installation using joints such as tenon and mortise joints or bolts results in cumbersome installation procedures and complex manufacturing processes.

[0004] Regarding the aforementioned technologies, the inventor believes it is currently necessary to improve the structure and paving method of slope protection blocks, simplify the paving process and manufacturing technology of slope protection blocks, and improve paving efficiency while ensuring the installation stability of slope protection blocks.

[0024] A slope protection structure includes a first slope protection layer and a second slope protection layer. The slope protection blocks in the first slope protection layer and the slope protection blocks in the second slope protection layer are connected in a cross shape.

[0030] In summary, this utility model provides a slope protection block and slope protection structure, which has the following beneficial effects:

[0031] First, this invention, through the shape and size of the first, second, and / or third blocks, ensures that the connection structure of the slope protection blocks is formed perpendicular to the paving surface. The slope protection blocks can be interlocked by overlapping vertically, forming a woven-like integrated slope protection structure. In this structure, except for the edge blocks, each block is constrained by its adjacent blocks in four directions (front, back, left, and right), and the lower blocks are constrained by the blocks above them, thus forming a slope protection structure with a three-dimensional constrained grid. This achieves stable paving without the introduction of other connectors. In practical implementation, limiting structures can be introduced to restrict the edge blocks, further improving the overall stability of the slope protection structure.

[0032] Secondly, the slope protection block of this utility model does not have connecting parts, so there is no need to set the mounting holes for installing the connecting parts, thus avoiding the situation where stress is concentrated at the mounting holes, which would cause the connection parts of the slope protection block to be easily damaged.

[0033] Third, the slope protection blocks of this utility model are laid in a cross-stacked manner, which makes it easy to distribute the external loads such as external water flow impact and soil pressure acting on the joints of the slope protection blocks to the slope protection blocks in their three-dimensional connection direction, thereby reducing the stress at the joints of the slope protection blocks and improving the stability of the slope protection structure.

[0034] Fourth, in some embodiments of this utility model, the slope protection structure can form a continuous waterway. When the slope protection structure is set up near water, the waterway can accelerate the discharge of water flowing towards the slope protection structure, release the water flow from scouring the slope protection structure, and effectively protect the bank slope.

[0035] Fifth, the slope protection structure of this utility model has permeable holes, which facilitates slope drainage, promotes sediment settling, reduces hydrostatic pressure, and reduces soil softening. In addition, the permeable holes are conducive to plant growth, further enhancing the effect of preventing soil erosion on the slope. Attached Figure Description

[0063] Example 1

[0064] This embodiment first discloses a slope protection block 111, referring to... Figure 1It consists of two first blocks 1111, two second blocks 1112, and one third block 1113. The two first blocks 1111, two second blocks 1112, and one third block 1113 are connected along a straight line. The two second blocks 1112 are connected to opposite sides of the third block 1113, and the first blocks 1111 are connected to the outside of the second blocks 1112. With the central axis of the third block 1113 as the axis of symmetry, the two second blocks 1112 and the two first blocks 1111 are mirror-symmetrical. The slope protection block 111 can be a one-piece molded structure, for example, cast in one piece from concrete. Optionally, a steel cage structure can be provided in the slope protection block 111.

[0065] Reference Figure 1 The thickness D2 of the second block 1112 is greater than the thickness D3 of the third block 1113, and the maximum thickness of the slope protection block 111 is n times the minimum thickness. In one specific embodiment, n is a positive integer greater than or equal to 2. For example, in this embodiment, the thickness D3 of the third block 1113 is equal to the thickness D1 of the first block 1111, and the thickness D2 of the second block 1112 is twice the thickness D3 of the third block 1113 or twice the thickness D2 of the first block 1111. The lower end faces of the first block 1111, the second block 1112, and the third block 1113 are flush, making the lower end 1115 of the slope protection block 111 a plane. By setting different thicknesses of the first block 1111, the second block 1112, and the third block 1113, the upper end 1114 of the slope protection block 111 forms a concave portion and a convex portion. The slope protection blocks 111 installed adjacent to each other are interlocked through the concave portion and the convex portion.

[0066] Reference Figure 1 The slope protection block 111 has a length-to-width ratio of 4:1. Specifically, the cross-sectional shape of the second block 1112 is exactly the same as that of the third block 1113, and the cross-sectional shape formed by horizontally joining two first blocks 1111 is exactly the same as that of the third block 1113. In this embodiment, the cross-sections of the second block 1112 and the third block 1113 are square, and the cross-section of the first block 1111 is rectangular. That is, the length of the short side of the first block 1111 is half the side length of the third block 1113 or the second block 1112, and the length of the long side of the first block 1111 is equal to the side length of the third block 1113 or the second block 1112. The two first blocks 1111 have the same shape, and the shape formed by horizontally joining two first blocks 1111 is exactly the same as that of the third block 1113. In this embodiment, all edges of the slope protection block 111 are rounded or chamfered to reduce water erosion damage. In other embodiments, the aspect ratio of the slope protection block 111 can be made a multiple of the other two by changing the number and connection order of the first block 1111, the second block 1112, and the third block 1113.

[0067] Reference Figure 2 In some other embodiments, the cross-sections of the second block 1112 and the third block 1113 are regular octagons, and the cross-section of the first block 1111 is half of the regular octagon. That is, the length of the major axis of the first block 1111 is equal to the length of the center line M of the second block 1112 or the third block 1113, and the length of the minor axis of the first block 1111 is equal to 1 / 2 the length of the center line M of the second block 1112 or the third block 1113.

[0068] Reference Figure 3 In another specific embodiment, the thickness of the third block 1113 is equal to the thickness of the first block 1111, and the thickness of the second block 1112 is three times the thickness of the third block 1113 or the thickness of the first block 1111. The first block 1111 and the third block 1113 are respectively connected to the middle of the second block 1112, and all the first blocks 1111 and the third blocks 1113 are located on the same plane.

[0069] This embodiment also discloses a slope protection structure 1, which is formed by splicing together the slope protection blocks 111 described in this embodiment.

[0070] Reference Figure 4 The slope protection structure 1 includes a first slope protection layer 11 and a second slope protection layer 12. The second slope protection layer 12 is located above the first slope protection layer 11. The slope protection blocks 111 in the first slope protection layer 11 and the slope protection blocks 111 in the second slope protection layer 12 are connected in a cross shape.

[0071] Specifically, refer to Figure 4 In the first slope protection layer 11, the lower end 1115 of the slope protection block 111 is attached to the paved surface, and the upper end 1114 faces upward. In the second slope protection layer 12, the upper end 1114 of the slope protection block 111 faces downward and is locked with the slope protection block 111 in the first slope protection layer 11.

[0072] Reference Figure 4 In the first slope protection layer 11, along the length direction of the slope protection block 111, the side end faces of the first block 1111 of adjacent slope protection blocks 111 abut against each other to form a splicing area 1116; along the width direction of the slope protection block 111, a gap area 1117 is provided between adjacent slope protection blocks 111, and the length of the gap area 1117 is equal to the width of the slope protection block 111.

[0073] Reference Figure 4 The length direction of the slope protection block 111 in the second slope protection layer 12 is cross-shaped with the length direction of the slope protection block 111 in the first slope protection layer 11. The third block 1113 and the first block 1111 of the slope protection block 111 in the second slope protection layer 12 are located in the splicing area 1116, and the second block 1112 is located in the interval area 1117.

[0074] Reference Figure 4 A passage is formed between the third blocks 1113 of the first slope protection layer 11 in the same column. This passage is indicated by arrow A in the figure. When the slope protection structure 1 is used for water-facing paving, the passage is set towards the water so that the water flowing into the slope protection structure 1 can flow out of the passage in the direction of A, thereby releasing the water flow from scouring the slope.

[0075] This embodiment also discloses a paving method, in which the slope protection blocks 111 of this embodiment are paved according to the paving method to form the slope protection structure 1 of this embodiment. The method includes the following steps:

[0076] S1, the slope protection blocks 111 are laid along the paving surface. Along the length direction of the slope protection blocks 111, the first blocks 1111 of adjacent slope protection blocks 111 abut against each other to form a splicing area 1116. Along the width direction of the slope protection blocks 111, a gap area 1117 is set between adjacent slope protection blocks 111. The distance of the gap area 1117 is equal to the width of the slope protection blocks 111, forming the first slope protection layer 11.

[0077] S2, the slope protection blocks 111 are laid on the upper end 1114 of the first slope protection layer 11 to form the second slope protection layer 12. The upper end 1114 of the slope protection blocks 111 in the second slope protection layer 12 faces the upper end 1114 of the slope protection blocks 111 in the first slope protection layer 11. The third block 1113 and the first block 1111 of the slope protection blocks 111 in the second slope protection layer 12 are located in the splicing area 1116, and the second block 1112 is located in the spacing area 1117, so that the slope protection blocks 111 in the second slope protection layer 12 and the slope protection blocks 111 in the first slope protection layer 11 form a cross-shaped connection.

[0078] Furthermore, referring to Figure 4 In this embodiment, when the slope protection structure 1 is laid near the water, the first slope protection layer 11 extends along the shoreline in the length direction, thus forming a slope protection structure 1 that forms a slope along the waterline. Figure 3 The waterway running through the center A direction can effectively reduce the erosion of the slope protection structure 1 by the water flow and protect the bank slope.

[0079] Reference Figure 5In another specific embodiment, an anchoring structure can also be added between the slope protection blocks 111. Specifically, anchoring holes 1118 can be opened on the outer side of the first block 1111 of the slope protection block 111. The anchoring hole 1118 only matches the partial shape of the fastener 13 to be inserted therein. That is to say, the anchoring hole 1118 is only a part of the fastener 13 mounting hole. The anchoring holes 1118 on the two slope protection blocks 111 spliced ​​end to end can be combined to form a complete fastener 13 mounting hole. When the slope protection blocks 111 with anchoring holes 1118 are laid to form the slope protection structure 1, at the cross-connection of the slope protection blocks 111 in the first slope protection layer 11 and the slope protection blocks 111 in the second slope protection layer 12, the fastener 13 is inserted into the mounting hole formed by the combination of the two anchoring holes 1118 for fixation. The fastener 13 can be a bolt.

[0082] Reference Figure 6 In this embodiment, the slope protection block 211 includes two first blocks 2111 and one second block 2112. The two first blocks 2111 are connected to opposite sides of the second block 2112, and are mirror-symmetrical about the central axis of the second block 2112. The lower end face of the first block 2111 and the lower end face of the second block 2112 are located in the same plane, making the lower end 2114 of the slope protection block 211 a plane.

[0083] Reference Figure 6 The slope protection block 211 has a length-to-width ratio of 2:1. The cross-sectional shape formed by horizontally splicing two first blocks 2111 is exactly the same as the cross-sectional shape of the second block 2112. Specifically, the cross-sectional shape of the second block 2112 is square, and the cross-sectional shape of the first block 2111 is rectangular. The length of the cross-section of the first block 2111 is half the side length of the second block 2112, and the width is equal to that of the second block 2112, so that the cross-section of the shape formed by splicing two first blocks 2111 is the same as that of the second block 2112. The thickness of the second block 2112 is twice the thickness of the first block 2111, so that the upper end 2113 of the slope protection block 211 forms a concave and a convex part. The slope protection blocks 211 installed vertically and vertically are interlocked through the concave and convex parts.

[0084] Of course, referring to Embodiment 1, the cross-section of the second block 2112 in this embodiment can also be a regular octagon, and the cross-section of the first block 2111 is half of the regular octagon, that is, the length of the major axis of the first block 2111 is equal to the length of the centerline of the second block 2112, and the length of the minor axis of the first block 2111 is equal to 1 / 2 of the length of the centerline of the second block 2112.

[0085] In this embodiment, the slope protection block 211 is laid using the same method as described in Embodiment 1 to form the slope protection structure 2. Figure 7 The slope protection structure 2 includes a first slope protection layer 21 and a second slope protection layer 22. The second slope protection layer 22 is located above the first slope protection layer 21. The slope protection blocks 211 in the first slope protection layer 21 and the slope protection blocks 211 in the second slope protection layer 22 are connected in a cross shape. Specifically, the lower end 2114 of the slope protection block 211 in the first slope protection layer 21 is in contact with the pavement surface, and the upper end 2113 faces upward. The upper end 2113 of the slope protection block 211 in the second slope protection layer 22 faces downward and is interlocked with the slope protection block 211 in the first slope protection layer 21.

[0086] Reference Figure 7 In the first slope protection layer 21, along the length direction of the slope protection block 211, the side end faces of the first block 2111 of the adjacent slope protection block 211 abut against each other to form a splicing area 2115; along the width direction of the slope protection block 211, a gap area 2116 is set between the adjacent slope protection blocks 211, and the length of the gap area 2116 is equal to the width of the slope protection block 211.

[0087] Reference Figure 7 The length direction of the slope protection block 211 in the second slope protection layer 22 intersects the length direction of the slope protection block 211 in the first slope protection layer 21 in a cross shape. The first block 2111 of the slope protection block 211 in the second slope protection layer 22 is located in the splicing area 2115, and the second block 2112 is located in the interval area 2116.

[0089] Reference Figure 8 This embodiment discloses a slope protection block 311. The slope protection block 311 differs from that in Embodiment 1 only in that: two first blocks 3111 are centrally symmetrically arranged on the outside of the second block 3112 along the center of the third block 3113. The lower end faces of the first block 3111, the second block 3112, and the third block 3113 are not flush. Specifically, the upper end face of one first block 3111 is on the same plane as the upper end face of the second block 3112, and the lower end face of one first block 3111 is on the same plane as the lower end face of the second block 3112, so that the upper end 3114 and the lower end 3115 of the slope protection block 311 both have concave and convex portions.

Adjacent second blocks 5112 are connected by third blocks 5113. On the side end face of each second block 5112, a first block 5111 is connected to the end of the second block 5112 that is lateral to the third block 5113, and another first block 5111 is connected to the end of the second block 5112 that is lateral to the third block 5113.

[0094] Reference Figure 10 The four third blocks 5113 are connected end to end to form a closed structure. The middle part of the closed structure formed by the four third blocks 5113 is a first through hole 5117. The first through hole 5117 can be used as a water permeable hole and can also be used for plant growth.

In this embodiment, the cross-sections of the second block 5112 and the third block 5113 are regular octagons, and the cross-section of the first block 5111 is half a regular octagon. That is, the length of the minor axis of the first block 5111 is half the length of the centerline of the third block 5113 or the second block 5112, and the length of the major axis of the first block 5111 is equal to the length of the centerline of the third block 5113 or the second block 5112. The two first blocks 5111 have identical shapes, so that the shape formed by horizontally joining the two first blocks 5111 is completely identical to the shape of the third block 5113.

[0110] Reference Figure 13 In this embodiment, the slope protection blocks (111, 511) in the first slope protection layer 61 and the second slope protection layer 62 are only rectangular as specific examples. It can be imagined that, referring to Embodiments 1 and 4, when the first block 5111, the second block 5112, and the third block 5113 of the slope protection block 511 in the first slope protection layer 61 are all or part of regular octagons, and the first block 1111, the second block 1112, and the third block 1113 of the slope protection block 111 in the second slope protection layer 62 are all or part of regular octagons, it can also be implemented.

[0111] Reference Figure 13 A passage is formed between the third blocks 5113 of the first slope protection layer 61 in the same column. This passage is indicated by arrow A in the figure. When this slope protection structure 6 is used for water-facing paving, the passage is set towards the water so that the water flowing into the slope protection structure 6 can flow out from the passage in the direction of A, thereby releasing the water flow from scouring the slope.

The second block 1112 is located in the first through hole 5117 or the second through hole 5118. The first block 1111 is located in the splicing area 5116 of the first slope protection layer 61. The long sides of the overlapping first blocks (1111, 5111) in the first slope protection layer 61 and the second slope protection layer 62 are arranged in a cross shape. In the second slope protection layer 62, along the length direction of the slope protection blocks 111, two adjacent slope protection blocks 111 are connected end to end. Along the width direction of the slope protection blocks 111, there is a gap area 6211 between two adjacent slope protection blocks 111.

[0115] Furthermore, referring to Figure 13 In this embodiment, when the slope protection structure 6 is laid near the water, the slope protection blocks 111 in the second slope protection layer 62 are laid along the width direction of the shoreline, thus forming a slope protection structure 6 that extends along the waterfront.

Along the width direction of the slope protection blocks 311, a spacing area 7112 is provided between adjacent slope protection blocks 311. The distance of the spacing area 7112 is equal to the width of the slope protection blocks 311, forming the first slope protection layer 71.

[0124] S2, continue to lay the slope protection blocks 111 described in Embodiment 1 on the upper end of the first slope protection layer 71 to form the second slope protection layer 72.

[0125] In some other embodiments, the slope protection block 111 described in Embodiment 1 can serve as the first slope protection layer 71, and the slope protection block 311 described in Embodiment 3 can serve as the second slope protection layer 72, forming another slope protection structure 7.

[0126] Example 8

[0127] Reference Figure 15 This embodiment discloses a slope protection structure 8 and its paving method. The only difference from embodiment 7 is that the slope protection structure 8 includes a first slope protection layer 81 and a second slope protection layer 82. The second slope protection layer 82 is located above the first slope protection layer 81. The first slope protection layer is formed by combining slope protection blocks 411 as described in embodiment 4, with the upper end 4114 of the slope protection blocks 411 laid downwards. The second slope protection layer 82 is formed by combining slope protection blocks 111 as described in embodiment 1, with the upper end 1114 of the slope protection blocks 111 facing downwards and interlocking with the slope protection blocks 411. Furthermore, the slope protection blocks 411 in the first slope protection layer 81 and the slope protection blocks 111 in the second slope protection layer 82 are cross-connected.

[0128] Reference Figure 16 In some other embodiments, the slope protection block 111 described in Embodiment 1 is laid with its upper end 1114 facing upward to form a first slope protection layer 81, and the slope protection block 411 described in Embodiment 4 is laid with its upper end 4114 facing upward to form a second slope protection layer 82, thus forming another slope protection structure 8.

[0129] Reference Figure 16 In some other embodiments, slope protection blocks 111 can be laid in a cross pattern at the location of the third block 4113 of the slope protection block 411, with the upper end 1114 of the slope protection block 111 laid on the third block 4113 facing downwards, and the first block 1111 stacked on the third block 4113 of the slope protection block 411.

[0130] Of course, in some other embodiments, when the slope protection structure 8 of this embodiment is set near water, please refer to Embodiment 1. The third block 4113 of the slope protection block 411 is no longer cross-connected with the slope protection blocks, so that the third block 4113 of the same row of slope protection blocks 411 can form a continuous drainage channel.

[0131] The paving method is the same as that described in Example 7.

[0132] The slope protection structure formed by the slope protection block paving in the above embodiment has a woven-like structure. Each slope protection block is restricted by the adjacent slope protection blocks in the front, back, left and right directions. At the same time, the slope protection blocks below are restricted by the slope protection blocks above them, thus forming a slope protection structure with a three-dimensional constraint grid. After the upper and lower cross paving is completed, it can limit the slope protection blocks. Stable paving effect can be achieved without the introduction of other connectors. Moreover, when no connectors are required, the paving can achieve the effect of simple and efficient process.

[0133] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it.
