Technical Field

[0001] The present invention relates to the technical field of water area embankment protection, in particular to a slope protection block, a slope protection structure and a paving method thereof. Background Art

[0002] Slope protection blocks are block structures installed on earth slopes or embankment surfaces facing water areas to prevent rockfall on steep slopes and soil and water loss on embankments.

[0003] To improve the installation stability of slope protection blocks, most current slope protection blocks are connected by side connections, forming a single slope protection structure that covers the slope surface. Examples include the spliced slope protection blocks described in Chinese Patent Publication No. CN222575520U and the improved slope protection block structure described in Chinese Patent Publication No. TW319259U. These slope protection blocks, which utilize connections such as mortise and tenon joints or bolts, suffer from cumbersome installation procedures and complex manufacturing processes.

[0004] In view of the above-mentioned related technologies, the inventor believes that it is currently very necessary to improve the structure and paving method of the slope protection blocks, simplify the paving process and manufacturing process of the slope protection blocks, and improve the paving efficiency while ensuring the installation stability of the slope protection blocks. Summary of the Invention

[0023] The present invention also provides a slope protection structure, which is composed of the above-mentioned slope protection blocks and specifically adopts the following technical solutions:

[0024] A slope protection structure includes a first slope protection layer and a second slope protection layer, wherein the slope protection blocks in the first slope protection layer and the slope protection blocks in the second slope protection layer are cross-connected up and down, and the first slope protection layer and the second slope protection layer are both formed by splicing the above-mentioned slope protection blocks, the aspect ratio of the slope protection blocks is 1:1, and one end of the first block, the second block, and the third block in the thickness direction is located in the same plane.

[0030] The present invention also provides a method for paving the slope protection blocks to form the slope protection structure, comprising the following steps:

[0031] S1, paving the slope protection blocks along a paved surface, with the first blocks of adjacent slope protection blocks abutting against each other to form a first slope protection layer;

[0032] S2, paving the slope protection blocks on the first slope protection layer to form a second slope protection layer, wherein the slope protection blocks in the second slope protection layer are cross-connected with the slope protection blocks in the first slope protection layer.

[0033] In one embodiment, an anchor hole is provided on the outer side of the first block, and a fastener is inserted into the anchor hole to fix the slope protection block in the first slope protection layer and the slope protection block in the second slope protection layer at a cross connection.

[0034] In summary, the present invention provides a slope protection block, a slope protection structure and a paving method thereof, which have the following beneficial effects:

[0035] First, the present invention sets the shape and size of the first block, the second block and / or the third block so that the connection structure of the slope protection block is formed in a direction perpendicular to the paving surface. The slope protection blocks can be interlocked in a cross-stacked manner to form an integral slope protection structure similar to weaving. In this slope protection structure, except for the slope protection blocks at the edge, each slope protection block can be restricted by the adjacent slope protection blocks in the front, back, left and right directions. At the same time, the lower slope protection block is restricted by the slope protection block above it, thereby forming a slope protection structure with a three-dimensional constraint grid, which can achieve a stable paving effect without introducing other connecting parts. In the specific implementation process, a limiting structure can also be introduced to limit the slope protection blocks at the edge, so that the overall stability of the slope protection structure of the present invention is improved.

[0036] Secondly, the slope protection block of the present invention does not have a connector, so there is no need to provide a mounting hole for mounting the connector, thereby avoiding the situation where stress is concentrated at the mounting hole and the connection part of the slope protection block is easily damaged.

[0037] Third, the slope protection blocks of the present invention are laid crosswise and stacked up and down, which can easily disperse the external loads such as external water impact and soil pressure acting on the joints of the slope protection blocks to the slope protection blocks in the 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.

[0038] Fourth, the slope protection structure formed in some embodiments of the present invention can form a continuous waterway. When the slope protection structure is set near water, the waterway can accelerate the discharge of water flowing to the slope protection structure, release the water flow to scour the slope protection structure, and effectively protect the bank slope.

[0039] Fifth, the slope protection structure of the present invention has water-permeable holes, which facilitate drainage of the slope and are beneficial to sedimentation. It has the effect of reducing hydrostatic pressure and reducing soil softening. In addition, the water-permeable holes are beneficial to plant growth, further enhancing the effect of preventing soil erosion on the slope. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0067] Example 1

[0068] This embodiment first discloses a slope protection block 111, referring to Figure 1 , consisting 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, with the two second blocks 1112 connected to opposite sides of the third block 1113, and the first block 1111 connected to the outside of the second block 1112. With the central axis of the third block 1113 as the axis of symmetry, the two second blocks 1112 are mirror-symmetrical, and the two first blocks 1111 are mirror-symmetrical. The slope protection block 111 can be an integrally formed structure, for example, integrally formed by pouring concrete. Optionally, a steel cage structure can be provided in the slope protection block 111.

[0069] Reference Figure 1 The thickness D2 of the second block 1112 is greater than the thickness D3 of the third block 1113. 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 the thickness D2 of the first block 1111. The lower end surfaces of the first, second, and third blocks 1111, 1112, and 1113 are flush, making the lower end 1115 of the slope protection block 111 a flat surface. The different thicknesses of the first, second, and third blocks 1111, 1112, and 1113 form a concave and convex portion at the upper end 1114 of the slope protection block 111. The concave and convex portions of the adjacent slope protection blocks 111 are interlocked.

[0070] Reference Figure 1The aspect ratio of the slope protection block 111 is 4:1. Specifically, the cross-sectional shape of the second block 1112 is identical to that of the third block 1113, and the cross-sectional shape formed by horizontally joining the two first blocks 1111 is identical to that of the third block 1113. In this embodiment, the cross-sectional shapes of the second and third blocks 1112, 1113 are square, while the cross-sectional shape of the first block 1111 is rectangular. Specifically, the short side of the first block 1111 is half the length of the side of the third block 1113 or the second block 1112, and the long side of the first block 1111 is equal to the length of the side of the third block 1113 or the second block 1112. The two first blocks 1111 are identical in shape, and the shape formed by horizontally joining the two first blocks 1111 is identical to that of the third block 1113. In this embodiment, all edges of the slope protection block 111 are rounded or chamfered to reduce water scouring damage. In some other embodiments, the length-to-width ratio of the slope protection block 111 can be made into another multiple of 2 by changing the number and connection sequence of the first block 1111, the second block 1112, and the third block 1113.

[0071] Reference Figure 2 In some other embodiments, the cross-section of the second block 1112 and the third block 1113 is a regular octagon, 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 midline 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 of the length of the midline M of the second block 1112 or the third block 1113.

[0072] Reference Figure 3 In another specific embodiment, the thickness of the third block 1113 is equal to the thickness of the first block 1111, the thickness of the second block 1112 is the thickness of the third block 1113 or three times the thickness of the first block 1111, the first block 1111 and the third block 1113 are respectively connected to the middle part of the second block 1112, and all the first blocks 1111 and third blocks 1113 are located in the same plane.

[0073] This embodiment further discloses a slope protection structure 1, which is formed by splicing the slope protection blocks 111 described in this embodiment.

[0074] 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 cross-connected.

[0075] Specifically, refer to Figure 4The lower end 1115 of the slope protection block 111 in the first slope protection layer 11 is in contact with the paving surface, and the upper end 1114 is facing upward. The upper end 1114 of the slope protection block 111 in the second slope protection layer 12 is facing downward and is locked with the slope protection block 111 in the first slope protection layer 11.

[0076] Reference Figure 4 In the first slope protection layer 11, along the length direction of the slope protection block 111, the side end surfaces 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 spacing area 1117 is set between adjacent slope protection blocks 111, and the length of the spacing area 1117 is equal to the width of the slope protection block 111.

[0077] Reference Figure 4 The length direction of the slope protection blocks 111 in the second slope protection layer 12 is cross-intersected with the length direction 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.

[0078] Reference Figure 4 A passage is formed between the third blocks 1113 of the first slope protection layer 11 located in the same row. The passage is indicated by arrow A in the figure. When the slope protection structure 1 is paved and used near water, the passage is set towards the water so that the water flowing into the slope protection structure 1 can flow out from the passage along the direction A to release the scouring of the slope protection by the water flow.

[0079] This embodiment also discloses a paving method, wherein 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:

[0080] S1, paving the slope protection blocks 111 along the paved surface, wherein the first blocks 1111 of adjacent slope protection blocks 111 abut against each other along the length direction of the slope protection blocks 111 to form a joint area 1116, and spacing areas 1117 are provided between adjacent slope protection blocks 111 along the width direction of the slope protection blocks 111, wherein the distance of the spacing areas 1117 is equal to the width of the slope protection blocks 111, thereby forming the first slope protection layer 11;

[0081] S2, paving the slope protection blocks 111 on the upper end 1114 of the first slope protection layer 11 to form the second slope protection layer 12, the upper ends 1114 of the slope protection blocks 111 in the second slope protection layer 12 face the upper ends 1114 of the slope protection blocks 111 in the first slope protection layer 11, the third blocks 1113 and the first blocks 1111 of the slope protection blocks 111 in the second slope protection layer 12 are located in the splicing area 1116, and the second blocks 1112 are 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 connection.

[0082] Further, refer to Figure 4 When the slope protection structure 1 of this embodiment is paved near the water, the length direction of the first slope protection layer 11 is extended along the water shoreline. The slope protection structure 1 thus formed will form a Figure 3 The waterway running through the middle A direction can effectively release the scouring of the water flow on the slope protection structure 1 and protect the bank slope.

[0083] Reference Figure 5 In another specific embodiment, anchoring structures can be added between the slope protection blocks 111. Specifically, anchoring holes 1118 can be provided on the outside of the first block 1111 of the slope protection block 111. These anchoring holes 1118 only partially match the shape of the fastener 13 to be inserted therein. In other words, the anchoring holes 1118 are only a portion of the mounting hole for the fastener 13. The anchoring holes 1118 on the two slope protection blocks 111 joined end to end can be combined to form a complete mounting hole for the fastener 13. When these slope protection blocks 111 with anchoring holes 1118 are laid to form the slope protection structure 1, the fastener 13 is inserted into the mounting hole formed by the two anchoring holes 1118 at the intersection 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 to secure the structure. The fastener 13 can be a bolt.

[0084] Example 2

[0085] This embodiment discloses a slope protection block 211 , a slope protection structure 2 and a laying method thereof, which differs from the embodiment 1 only in the structure of the slope protection block 211 .

[0086] 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 the two first blocks 2111 are mirror-symmetrical with the central axis of the second block 2112 as the axis of symmetry. The lower end surfaces of the first blocks 2111 and the lower end surfaces of the second block 2112 are located in the same plane, making the lower end 2114 of the slope protection block 211 a flat surface.

[0087] Reference Figure 6 The aspect ratio of the slope protection block 211 is 2:1. The cross-sectional shape formed by horizontally joining two first blocks 2111 is identical to the cross-sectional shape of the second block 2112. Specifically, the cross-sectional shape of the second block 2112 is square, while the cross-sectional shape of the first block 2111 is rectangular. The length of the cross-sectional shape of the first block 2111 is half the length of the side of the second block 2112, and the width is equal to that of the second block 2112. This ensures that the cross-sectional shape formed by joining the two first blocks 2111 is identical to the cross-sectional shape of the second block 2112. The thickness of the second block 2112 is twice that of the first block 2111, forming a concave and convex portion at the upper end 2113 of the slope protection block 211. The concave and convex portions allow the adjacent slope protection blocks 211 installed above and below to interlock.

[0088] Of course, referring to Example 1, the cross-section of the second block 2112 of 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 center line 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 center line of the second block 2112.

[0089] The slope protection blocks 211 in this embodiment are laid to form a slope protection structure 2 with reference to the laying method described in Example 1. 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 cross-connected. Specifically, the lower ends 2114 of the slope protection blocks 211 in the first slope protection layer 21 are in contact with the pavement surface, with the upper ends 2113 facing upward. The upper ends 2113 of the slope protection blocks 211 in the second slope protection layer 22 face downward and interlock with the slope protection blocks 211 in the first slope protection layer 21.

[0090] Reference Figure 7 In the first slope protection layer 21, along the length direction of the slope protection block 211, the side end surfaces of the first block 2111 of adjacent slope protection blocks 211 abut against each other to form a splicing area 2115; along the width direction of the slope protection block 211, a spacing area 2116 is set between adjacent slope protection blocks 211, and the length of the spacing area 2116 is equal to the width of the slope protection block 211.

[0091] Reference Figure 7 The length direction of the slope protection blocks 211 in the second slope protection layer 22 is cross-intersected with the length direction of the slope protection blocks 211 in the first slope protection layer 21. The first block 2111 of the slope protection blocks 211 in the second slope protection layer 22 is located in the splicing area 2115, and the second block 2112 is located in the spacing area 2116.

[0092] Example 3

[0093] Reference Figure 8 This embodiment discloses a slope protection block 311. The only difference between the slope protection block 311 and the embodiment 1 is that: the two first blocks 3111 are arranged symmetrically on the outside of the second block 3112 along the center of the third block 3113, and the lower end surfaces of the first block 3111, the second block 3112 and the third block 3113 are not flush. Specifically, the upper end surface of one first block 3111 and the upper end surface of the second block 3112 are in the same plane, and the lower end surface of one first block 3111 and the lower end surface of the second block 3112 are in the same plane, so that the upper end 3114 and the lower end 3115 of the slope protection block 311 both have concave and convex portions.

[0094] Example 4

[0095] Reference Figure 9 This embodiment discloses a slope protection block 411. The difference between the slope protection block 411 and the embodiment 1 is that: two second blocks 4112 are connected to the left and right sides of the third block 4113 in a mirror-symmetrical manner, and two first blocks 4111 are connected to the outside of the second block 4112 in a mirror-symmetrical manner. The lower end surfaces of the first block 4111, the second block 4112 and the third block 4113 are not flush. Specifically, the upper end surfaces of the two first blocks 4111 are both in the same plane as the upper end surface of the second block 4112, so that the upper end 4114 and the lower end 4115 of the slope protection block 411 have concave and convex portions.

[0096] Example 5

[0097] This embodiment first discloses a slope protection block 511, referring to Figure 10 , consisting of four second blocks 5112, four third blocks 5113, and eight first blocks 5111. The slope protection block 511 is square, that is, the aspect ratio of the slope protection block 511 is 1:1. The four second blocks 5112 are located at the four corners of the square, and two adjacent second blocks 5112 are connected by the third block 5113. On the side end face of each second block 5112, one first block 5111 is connected to the end away from the third block 5113 in the transverse direction of the second block 5112, and one first block 5111 is connected to the end away from the third block 5113 in the longitudinal direction of the second block 5112.

[0098] Reference Figure 10The four third blocks 5113 are connected end to end to form a closed structure. The middle 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.

[0099] Reference Figure 10 In this embodiment, the thickness of the third block 5113 is equal to that of the first block 5111, and the thickness of the second block 5112 is twice the thickness of the third block 5113 or the first block 5111. This results in the upper end 5114 of the slope protection block 511 having both a concave portion and a convex portion. The lower end surfaces of all the first blocks 5111, the second blocks 5112, and the third blocks 5113 are located in the same plane, making the lower end 5115 of the slope protection block 511 a flat surface.

In this embodiment, the cross-sectional shapes of the second block 5112 and the third block 5113 are regular octagons, and the cross-sectional shape 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 midline 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 midline of the third block 5113 or the second block 5112. The shapes of the two first blocks 5111 are identical, so that the shape formed by horizontally joining the two first blocks 5111 is identical to the shape of the third block 5113.

Along the width direction of the slope protection blocks 311, spacers 7112 are set between adjacent slope protection blocks 311. The distance of the spacers 7112 is equal to the width of the slope protection blocks 311, forming the first slope protection layer 71.

[0128] S2. Continue to pave the slope protection blocks 111 described in Example 1 on the upper end of the first slope protection layer 71 to form the second slope protection layer 72. The upper ends 1114 of the slope protection blocks 111 in the second slope protection layer 72 face the upper ends 3114 of the slope protection blocks 311 in the first slope protection layer 71.

[0130] Example 8

[0131] Reference Figure 15 This embodiment discloses a slope protection structure 8 and a paving method thereof, which differs from Example 7 only in 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 the slope protection blocks 411 described in Example 4, and the upper ends 4114 of the slope protection blocks 411 are laid downward, and the second slope protection layer 82 is formed by combining the slope protection blocks 111 described in Example 1, and the upper ends 1114 of the slope protection blocks 111 are downward and interlocked with the slope protection blocks 411, and 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.

[0132] Reference Figure 16 In some other embodiments, the upper end 1114 of the slope protection block 111 described in Example 1 is laid upward to form a first slope protection layer 81, and the upper end 4114 of the slope protection block 411 described in Example 4 is laid upward to form a second slope protection layer 82, forming another slope protection structure 8.

[0134] Of course, in some other embodiments, when the slope protection structure 8 of this embodiment is set near water, please refer to Example 1, the position of the third block 4113 of the slope protection block 411 is no longer cross-connected to the slope protection block, so that the third block 4113 of the same row of slope protection blocks 411 can form a continuous drainage channel.

[0135] The paving method refers to the paving method described in Example 7.

[0136] The slope protection structure formed by the slope protection blocks in the above embodiment has a structure similar to a weaving structure. Each slope protection block can be restricted by the adjacent slope protection blocks in the front, back, left and right directions. At the same time, the lower slope protection block is restricted by the slope protection block above it, thereby 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, and a stable paving effect can be achieved without introducing other connecting parts. When there is no need to install connecting parts, the paving can achieve a simple process and efficient effect.
