[0002] Slope protection is a commonly used engineering measure, especially in water-related slope protection. The protection of water-related slopes mainly solves the problems of slope protection to prevent water scouring, drain water seepage behind the slope protection, and eliminate wind and wave impact. The thickness and weight of the hard material slope protection depends on factors such as wind and wave scouring, the stability and durability of the slope protection itself, etc. The slope protection also needs to be able to adapt to the uneven settlement and deformation of the slope.

[0003] Based on the above characteristics, slope protection is generally constructed using stone masonry and concrete blocks. However, for a long time, there have been problems such as insufficient uniformity in stone specifications, poor wave-breaking effect of concrete block slope protection, contradiction between drainage and wave protection, weak integrity of the slope protection surface, poor ability to adapt to slope deformation, and unstable structure of the slope protection on the slope.

A limiting protrusion protruding from the first end face is formed in the interlocking recessed portion, and the limiting protrusion can be inserted into the limiting recessed portions of the other two building block bodies.

[0009] In some embodiments of the first aspect, four corners of the slope protection blocks are chamfered, and the chamfers of adjacent slope protection blocks can be combined to form a drainage channel.

[0010] In some embodiments of the first aspect, the interlocking protrusion further includes a limiting surface connecting the interlocking end surface and the first end surface, and the limiting surface extends obliquely from the first end surface toward a direction of enlarging the interlocking recess.

[0011] In some embodiments of the first aspect, the limiting protrusion includes a first limiting protrusion and a second limiting protrusion formed at intervals on the first end surface, and a drainage gap is formed between the first limiting protrusion and the second limiting protrusion, and the drainage gap is located in the middle part of the first end surface.

[0012] In some embodiments of the first aspect, a convex surface protruding outward or a concave surface recessed inward is formed on the slope protection surface.

[0013] In some embodiments of the first aspect, the slope protection surface is designed to be a plane.

[0014] The second aspect of the present application provides a slope protection, which is formed by splicing the slope protection blocks according to any one of the first aspects above, the second end faces of the slope protection blocks on the same layer are arranged adjacent to each other, the interlocking recessed portions of each slope protection block and the interlocking protruding portions of every two adjacent slope protection blocks on the adjacent layer are spliced ​​with each other, the first end face is butted against the two interlocking end faces and the limiting protruding portion is inserted into the limiting recessed portion to achieve locking.

[0015] In some embodiments of the second aspect, the four corners of the slope protection blocks are chamfered, and the chamfers of adjacent slope protection blocks in the slope protection are combined to form a drainage channel.

[0016] In some embodiments of the second aspect, the limiting protrusion includes a first limiting protrusion and a second limiting protrusion formed at intervals on the first end surface, and a drainage gap is formed between the first limiting protrusion and the second limiting protrusion, and the drainage gap is opposite to the drainage channel.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] (1) The slope protection blocks provided in at least one embodiment of the present application form interlocking between the assembled slope protection blocks by setting a chain structure. This interlocking exists in two directions, parallel to the slope surface and perpendicular to the slope surface, so that the slope protection blocks after masonry can maintain better integrity, have a more stable structure, can adapt to different forms of slopes, and greatly improve the wind and wave resistance of the blocks;

[0019] (2) The slope protection blocks provided in at least one embodiment of the present application are interlocked in both directions parallel to the slope surface and perpendicular to the slope surface. Under the same protection requirements, the thickness of the slope protection blocks can be reduced, thereby saving a large amount of engineering materials, engineering costs, reducing energy consumption and pollution.

[0020] (3) The slope protection blocks provided in at least one embodiment of the present application improve the drainage structure by forming drainage channels between the slope protection blocks, which can replace the direct opening of holes on the block body. The four corners of the slope protection blocks are chamfered. When the slope protection blocks are spliced ​​to form a slope protection, the chamfers of adjacent slope protection blocks are combined to form a drainage channel, which can drain the accumulated water at the bottom of the slope protection.

[0021] (3) The slope protection blocks provided in at least one embodiment of the present application do not set a draft angle on the combined splicing interface, so that the slope protection blocks of adjacent layers are close to each other in the longitudinal direction, which is conducive to the transmission of downward sliding force and the formation of a tight pre-pressure, has good anti-bending deformation ability, and basically does not have the problem of instability and overturning;

[0022] (4) The slope protection provided in at least one embodiment of the present application is formed by splicing the slope protection blocks provided in the present application. The four corners of the slope protection blocks are chamfered to prevent damage during transportation. This combined drainage channel can avoid opening holes in the middle of the blocks, greatly enhancing the integrity and overall strength of the blocks. The blocks without holes in the middle can be hoisted and transported over short distances using suction cups. Based on the hoisting performance of the suction cups, the blocks can be designed as prefabricated concrete blocks with a larger protection area, thereby improving the protection effect on the slope.

[0023] (5) The slope protection provided by at least one embodiment of the present application is formed by splicing the slope protection blocks provided by the present application. Since the upper surface of the blocks has concave or convex features, it can effectively increase the friction and impact of wind and waves on the slope, quickly consume the kinetic energy of wind and waves, reduce the height of wind and waves on the slope, and then increase the flood control capacity of the dam or dike.

[0024] (6) The slope protection provided by at least one embodiment of the present application is formed by splicing the slope protection blocks provided by the present application. Since the upper surface of the blocks can be designed as a plane feature, the surface roughness can be effectively reduced, thereby reducing the resistance to water flow. When used for lining the slope of a river channel, the water conveyance capacity of the river channel can be improved, thereby reducing the excavation section, saving energy and reducing emissions, and reducing construction costs and permanent land occupation.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can also be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed in this application, some changes in design, manufacturing or production based on the technical content disclosed in this application are just conventional technical means, and should not be understood as insufficient content disclosed in this application.

[0037] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those of ordinary skill in the art that the embodiments described in this application may be combined with other embodiments without conflict.

[0038] In the description of the present invention, it should be understood that the terms "transverse", "longitudinal", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0039] The first aspect of the embodiment of the present application provides a slope protection block 1, which is used as a unit for laying a slope protection 2. A plurality of slope protection blocks 1 can be spliced ​​to form a slope protection 2 with a required area. Figure 1-Figure 7 As shown, the slope protection block 1 provided in the embodiment of the present application includes a block body 11 and a locking protrusion 12 and a locking recess 13 formed on the block body 11. The locking protrusion 12 and the locking recess 13 of the slope protection block 1 are used to lock the relative positions of the mutually spliced ​​slope protection blocks 1, so as to achieve the laying of the slope protection 2 using the slope protection blocks 1.

[0040] The block body 11 includes a slope protection surface 111 for constituting the outer surface of the slope protection 2. The slope protection surface 111 is the surface directly subjected to the erosion of water waves. The block body 11 is made of precast concrete, which can be prefabricated in advance and has strong hardness, and can better resist the erosion of water waves.

[0041] In some embodiments, a convex surface protruding outward or a concave surface sunken inward can be formed on the slope protection surface 111. The convex surface or the concave surface can effectively decompose the kinetic energy of the wind and waves sliding on the slope surface when the wind and waves slide along the slope protection 2, so that the flow velocity component perpendicular to the slope surface generated by the water flow passes through a large area of ​​turbulence and turbulence, thereby reducing the energy of the wind and waves, reducing the height of the wind and waves, and reducing the destructive power of the wind and waves on the earth slope. At the same time, for projects such as dams and dikes, the elevation of the dam top or the dike top can be reduced, the project cost can be reduced, and the safety performance can be greatly improved. The slope protection block 1 with a concave surface or the slope protection block 1 with a convex surface can be used alone, or the slope protection blocks 1 with these two surface types can be used at the same time to form a slope protection 2.

[0042] In other embodiments, the slope protection surface 111 is designed to be a plane. In this case, the slope protection surface 111 can effectively reduce the surface roughness, thereby reducing the resistance to water flow. When used for river slope lining, it can improve the water conveyance capacity of the river, thereby reducing the excavation section, saving energy and reducing emissions, and reducing construction costs and permanent land occupation.

[0043] The block body 11 has an approximately rectangular shape, and the up-down direction of the block body 11 in the laying state is defined as the longitudinal direction, and the left-right direction is defined as the transverse direction. The block body 11 includes two first end faces 101 (i.e., the upper end face and the lower end face) located in the longitudinal direction and two second end faces 102 (i.e., the left end face and the right end face) located in the transverse direction. The interlocking protrusion 12 is formed protrudingly at both ends of the first end face 101 along the longitudinal direction; the interlocking recess 13 is located between the two interlocking protrusions 12, and is composed of the first end face 101 and the side surfaces of the two interlocking protrusions 12 located at both ends of the first end face 101.

[0044] like Figure 1 As shown, a slope protection block 1 has four interlocking protrusions 12 and two interlocking recesses 13. The four interlocking protrusions 12 are respectively formed protrudingly at both ends of the upper end surface and the lower end surface, and the interlocking recess 13 is located between two interlocking protrusions 12 on the same side.

[0045] The interlocking protrusion 12 includes an interlocking end face 121 protruding from the block body 11 in the longitudinal direction, and the interlocking protrusion 12 is provided with a limiting recess 122 penetrating the interlocking end face 121 in the transverse direction, and the opening of the limiting recess 122 faces the outside of the block; a limiting protrusion 131 protruding from the first end face 101 is formed in the interlocking recess 13. The matching of the limiting recess 122 and the limiting protrusion 131 between the slope protection blocks 1 can realize the mutual locking of the slope protection blocks 1 in two directions parallel to the slope surface and perpendicular to the slope surface.

[0046] Specifically, the shape of the interlocking recess 13 matches the shape of the two interlocking protrusions 12 when assembled. It can be understood that the shape of the interlocking recess 13 matches the shape of the interlocking protrusion 12 and the shape of the interlocking protrusion 12 after the mirror symmetry of the interlocking protrusion 12 relative to the second end face 102 is superimposed. Figure 3-Figure 5 The limiting protrusion 131 can be inserted into the limiting recess 122 of the other two block bodies 11 assembled with it, so as to achieve locking. Figure 1-Figure 3 As shown, the limiting recessed portion 122 is a keyway, and the limiting protruding portion 131 is a key bar; in other embodiments, such as Figure 6 and Figure 7 As shown, when the thickness of the slope protection block 1 is relatively thin, the limiting recessed portion 122 is designed as a semi-open recessed portion, and the limiting protruding portion 131 is designed as a protruding portion that matches the thickness of the recessed portion.

[0047] The slope protection blocks 1 with interlocking function provided in the first aspect of the present application have uniform specifications and can be prefabricated in advance with concrete; by setting up an interlocking structure, the stability in the direction perpendicular to the slope protection surface is increased, and it can adapt to slopes of different forms; multiple slope protection blocks 1 are laid to form the required slope protection 2, and the assembled slope protection blocks 1 are interlocked with each other, so that the slope protection 2 after masonry maintains better integrity as a whole, has a relatively stable structure, and greatly improves the wind and wave resistance of the blocks; at the same time, the design thickness of the slope protection blocks 1 can be reduced, the amount of concrete used can be reduced, and good economic effects can be achieved.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, the interlocking protrusion 12 also includes a limiting surface 123 connecting the interlocking end surface 121 and the first end surface 101, and the limiting surface 123 extends obliquely from the first end surface 101 toward the direction of expanding the interlocking recessed portion 13, so that each interlocking protrusion 12 has an approximately trapezoidal shape. The interlocking recessed portion 13 with a gradually expanding opening can facilitate the splicing of the interlocking recessed portion 13 of the slope protection block 1 with the interlocking protrusion of the slope protection block 1 of the adjacent layer during the laying process of the slope protection block 1, and the limiting surfaces 123 of each slope protection block 1 after splicing are mutually limited in the lateral direction, further improving the stability of the slope protection block 1 after splicing.

[0049] Traditional prefabricated concrete blocks usually have drainage holes in the middle to drain water seepage and water seepage pressure behind the slope protection to prevent floating and overturning. However, directly drilling holes in concrete blocks will cause structural damage to the blocks, increase the difficulty of prefabrication, and is not conducive to the transportation and installation of blocks using mechanical devices such as suction cups.

[0050] The slope protection block 1 provided in the present application improves the above-mentioned problem, forming a drainage channel 21 that runs through the upper and lower surfaces of the slope protection 2, avoiding opening holes directly on the block. Specifically, in some embodiments, the four corners of the slope protection block 1 are chamfered 124. When the slope protection blocks are spliced ​​to form a slope protection, the chamfers 124 of adjacent slope protection blocks are combined to form a drainage channel, which can drain the accumulated water at the bottom of the slope protection. Figure 3 , Figure 4 and Figure 7 As shown, when the second end faces 102 of two adjacent slope protection blocks 1 of the same layer are relatively assembled, a drainage channel 21 penetrating the slope protection 2 is formed. This combined drainage channel can avoid opening a hole in the middle of the block, greatly enhancing the integrity and overall strength of the block. The block without a hole in the middle can be hoisted and transported over a short distance with a suction cup. Based on the hoisting performance of the suction cup, the block can be designed as a concrete prefabricated block monomer with a larger protection area, thereby improving the protection effect on the slope. In addition, the four corners of the slope protection block 1 are chamfered to prevent the edges of the block from collision and damage.

[0051] Furthermore, if Figure 1 As shown, the limiting protrusion 131 formed in the interlocking recess 13 includes a first limiting protrusion 1311 and a second limiting protrusion 1312 formed at intervals on the first end surface 101, and a drainage gap 132 is formed between the first limiting protrusion 1311 and the second limiting protrusion 1312, and the drainage gap 132 is located in the middle of the first end surface 101. When the slope protection blocks 1 are spliced, the interlocking protrusions 12 of two adjacent layers of slope protection blocks 1 are spliced ​​into the interlocking recess 13 of the slope protection blocks 1, and the limiting protrusion 131 is inserted into the limiting recess 122. At this time, the drainage gap 132 corresponds to the drainage channel 21 between the two drainage surfaces 124 in the vertical direction.

[0052] The upper and lower end faces of traditional precast concrete blocks are often designed with draft angles due to the needs of the mold, resulting in the upper and lower end faces being not perpendicular to the slope protection surface. When the blocks are laid and installed, the joint surfaces of each block are not closely fitted, which is manifested as chamfered gaps reserved between adjacent blocks. These chamfered gaps can remain stable in the horizontal direction because there is no squeezing caused by the sliding force; however, the chamfered gaps in the vertical direction will present a single-sided line contact under the squeezing of the sliding force, resulting in obvious instability and failure characteristics of the slope protection laid on the slope surface. When the slope protection is subjected to the pull-out force of wind and waves, the buoyancy of water seepage at the bottom of the slope protection, and other forces perpendicular to the slope protection surface, the slope protection is prone to instability and overturning.

[0053] In the slope protection block 1 provided in the embodiment of the present application, a locking protrusion 12 and a locking recess 13 are provided on the first longitudinal end face 101, and adjacent layers can be locked with each other in the longitudinal direction through the locking protrusion 12 and the locking recess 13. In addition, in some embodiments, the first end face 101 can be set to be perpendicular to the slope protection surface 111, that is, no draft angle is set, so that the slope protection blocks 1 of adjacent layers can be closely attached to each other in the longitudinal direction without chamfering gaps, which is conducive to the transmission of the sliding force based on the slope angle α and the formation of a tight pre-pressure, and each slope protection block 1 is tightly attached together under the action of the sliding force (such as Figure 5 As shown), it has good anti-bending deformation ability outside the slope. In this case, the slope protection 2 is subjected to the pulling force of wind and waves, the buoyancy of water seepage at the bottom of the slope protection 2 and other forces perpendicular to the slope protection surface 111, and it is difficult to have the problem of instability and overturning.

[0054] The second aspect of the embodiment of the present application provides a slope protection 2 formed by splicing the slope protection blocks 1 of any embodiment of the first aspect. Figure 3 , Figure 4 and Figure 7As shown, in the slope protection 2, the second end faces 102 of the slope protection blocks 1 of the same layer (i.e., the slope protection blocks 1 arranged in the transverse direction) are arranged adjacent to each other, the interlocking recessed portion 13 of each slope protection block 1 is spliced ​​with the interlocking protruding portions 12 of every two adjacent slope protection blocks 1 of the adjacent layer (i.e., the slope protection blocks 1 arranged in the longitudinal direction), the first end face 101 is butted against the two interlocking end faces 121, and the limiting protruding portion 131 is inserted into the limiting recessed portion 122.

[0055] The slope protection 2 provided in the above embodiments of the present application is formed by splicing the slope protection blocks 1 provided in the first aspect, and a pre-pressure is formed in the longitudinal direction by means of the downward force generated by the slope angle of the slope surface, so as to achieve a close fit and locking in the longitudinal direction. The slope protection blocks 1 on the same layer can be locked in the transverse direction by the limiting surface 123 after the interlocking protrusions 12 and the interlocking recesses 13 are spliced ​​together. The slope protection 2 formed in this way can adapt to different forms of slopes, maintain better integrity as a whole, have a relatively stable structure, and improve the ability to resist wind and waves.

[0056] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0057] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
