Description

Technical Field

[0001] The invention belongs to the technical field of slope protection, and in particular relates to a hexagonal slope protection brick, a slope protection component using the slope protection brick, and a slope protection system. Background Art

[0002] Slope protection refers to the general term for various paving and planting on the slope surface to prevent the slope from being eroded. The design of slope protection should first meet the requirements of slope stability. The main instability factors of the slope are: ① instability caused by gradual erosion of the slope surface; ② instability caused by sliding and damage of the surface soil; ③ instability caused by sliding of the deep soil. Since traditional slope protection bricks are single in form, most of them are square bricks or hexagonal bricks with pure hard structures directly laid on the slope to form a slope surface, the above-mentioned instability phenomenon often causes slope displacement along the slope surface and / or vertical slope surface sinking or upturning between two adjacent slope protection bricks or a single slope protection brick, that is, normal displacement. In addition, the top surface of traditional hexagonal slope protection bricks is generally a plane with through holes. When excessive rainwater erodes, the soil or plants in the through holes of the hexagonal blocks are easily washed away by rainwater. The above-mentioned slope displacement, normal displacement and soil erosion can easily cause deformation or even landslide of the slope, seriously affecting the stability and safety of the slope, and may even cause damage to civil engineering equipment on and around the slope, thereby causing many troubles in the actual slope protection operation. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and to provide a hexagonal slope protection brick with simple structure and convenient construction, a slope protection component and a slope protection system using the slope protection brick, which can achieve the anti-sinking, anti-slip and anti-scouring functions of the hexagonal slope protection bricks, the slope protection component and even the entire slope protection system through the cooperation between the hexagonal slope protection bricks.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A hexagonal slope protection brick comprises a block body with six sides whose top surface is a parallelepiped, and is characterized in that: the lower part of one side surface of the block body protrudes outward to form a lower convexity, and the upper part of the lower convexity forms an upper slot correspondingly, and the lower part of the other side surface adjacent to the side surface is recessed inwardly so that the upper part of the side surface forms an upper eaves, and the lower part recessed inwardly below the upper eaves forms a lower slot correspondingly; the upper eaves or the lower convexity are arranged on the opposite surface of the side surface where the lower convexity is located, and the lower convexity or the upper eaves are arranged on the opposite surface of the side surface where the upper eaves is located; the groove length direction of the lower slot and the upper slot extends along the side length direction of the side of the parallelepiped where the current slot is located.

[0006] Preferably, the cross-sectional shape of the lower slot is matched with the cross-sectional shape of the lower convex; the cross-sectional shape of the upper slot is matched with the cross-sectional shape of the upper eave.

[0007] Preferably, one end of the lower slot along the length direction of the slot is open for easy demoulding and for insertion of the lower protrusion of the adjacent block, and the other end is closed, thereby forming a single-end sealed slot-shaped lower slot.

[0008] Preferably, the top surface of the upper eaves and the top surface of the block are in the same plane; the bottom surface of the downward convexity and the bottom surface of the block are in the same plane.

[0009] Preferably, the bottom surface of the upper eave and the downwardly convex top surface are structures that are convenient for demoulding.

[0010] Preferably, the top surface of the block is a regular hexagonal block polygon.

[0011] Preferably, a through hole is vertically penetrated through the block.

[0012] Preferably, a water-blocking ridge is further provided on the top surface of the block, and the water-blocking ridge surrounds the through hole to form a waterproof ring structure.

[0013] A slope protection assembly using the hexagonal slope protection bricks comprises two hexagonal slope protection bricks, characterized in that the lower slot of one of the hexagonal slope protection bricks is plugged into the lower convexity of the other hexagonal slope protection brick, or the upper slot of one of the hexagonal slope protection bricks is plugged into the upper eaves of the other hexagonal slope protection brick.

[0014] A slope protection system using the slope protection components is characterized in that the slope protection components are plugged into each other in sequence to form a planar protection system.

[0015] The beneficial effects of the present invention are:

[0016] 1) The original hexagonal block structure with a traditional single smooth side structure is abandoned, and an upper eave or lower convexity is arranged on the side of the originally smooth block, so that the two adjacent hexagonal block slope protection bricks have a physical connection function when in use. In actual operation, due to the plug-in function of the lower slot formed by the upper eaves of the two adjacent hexagonal block slope protection bricks and the lower convexity, or the plug-in function of the upper slot formed by the lower convexity and the upper eaves, it is ensured that the block is at least constrained in the direction perpendicular to the brick surface, that is, the purpose of preventing sinking and warping is achieved.

[0017] It is worth noting that: on the one hand, the convexity is to protrude from the side of the original hexagonal block, while the lower slot is concave relative to the side of the original hexagonal block; that is, the upper slot is formed by "addition" on the basis of the original side, and the lower slot is formed by "subtraction" on the basis of the original side. Through this type of structure, two adjacent hexagonal blocks of the present invention can be physically connected, and each hexagonal block presents the original hexagonal block structure in people's sight to ensure practicality and aesthetics. On the other hand, since the slot length direction of the adjacent lower slot and the slot length direction of the upper slot both extend along the length direction of the hexagonal side of the top surface of the block, that is, each slot is arranged obliquely or horizontally, and the extension paths of the two groups of slots in space do not interfere with each other; in other words, during processing, the present invention can be considered to be manufactured by a core-pulling mold. The non-interference of the above extension path allows the core mold to be pulled out unimpeded in its own horizontal demolding direction, and then the above-mentioned lower slot is formed without interfering with the normal movement of the upper and lower molds; and the upper slot formed by the lower convexity is naturally formed by the vertical demolding of the upper mold. Once matched, no matter whether the internal soil layer slides or the external rainwater scours, the two adjacent blocks will not sink, warp or fall off, thereby effectively ensuring the slope reinforcement and protection effect. Of course, in actual design, it is also possible to use other existing known technologies for processing and manufacturing instead of the core pulling mold method, which will not be repeated here.

[0018] 2) As a further preferred solution of the present invention, in order to ensure that each hexagonal slope protection brick can be reliably assembled at will, the lower slot formed by the upper eaves of each hexagonal slope protection brick can be adapted by any lower protrusion; similarly, the upper slot formed by the lower protrusion of each hexagonal slope protection brick can also be plugged into any upper eaves. In actual use, it is not required that the two blocks are completely matched when plugged in, or due to manufacturing errors, human design, or even due to the unevenness of the construction site, it is also allowed that the mating surfaces of two adjacent blocks have a certain matching gap in height or horizontal direction.

[0019] 3) Furthermore, when two adjacent hexagonal slope protection bricks are horizontally assembled through the upper eaves and the lower convexity, they can actually only achieve the anti-sinking and anti-warping function in the direction perpendicular to the brick surface. In order to further achieve the anti-slip function of the two hexagonal slope protection bricks in the slope direction, the present invention changes the lower slot from a through slot to a single-end sealed slot. In this way, once the lower slot and the lower convexity at the upper eaves of the two adjacent hexagonal slope protection bricks are engaged with each other, the sinking and warping action of the two hexagonal slope protection bricks is limited by the plug-in fit of the upper eaves and the lower convexity, and the sliding action of the two hexagonal slope protection bricks along the slope is limited by the mutual abutment relationship between the closed end of the lower slot and the side of the lower convexity, which ultimately ensures that the slope has overall anti-translation and anti-sinking properties, with significant results.

[0020] 4) Furthermore, the upper eaves and the lower convexities may not be in the same plane as the corresponding surfaces of the block during actual design, and height differences are permissible; in other words, the upper slot and the lower slot may be straight slots with two groove walls, or may be notched slots with one side of the groove wall missing. The present invention preferably has the top surface of the upper eaves and the top surface of the block in the same plane, and the bottom surface of the lower convexities and the bottom surface of the block in the same plane, that is, the upper slot and the lower slot are preferably notched slots with single-sided groove walls or similar to V-shaped grooves, which is conducive to simplifying the production cost of the present invention and improving the production efficiency of the present invention; at the same time, once the hexagonal slope protection bricks are assembled with each other, the gap between two adjacent hexagonal slope protection bricks can also be reduced as much as possible, thereby reducing the amount of rainwater infiltration along the gap.

[0021] 5) When actually performing the demolding operation, it is more desirable that the mating surface between the mold and the finished product presents an inclined surface structure that is convenient for demolding. Therefore, the bottom surface of the upper eave and the downwardly convex top surface of the present invention present a structure that is convenient for demolding, which will not be repeated here.

[0022] 6) The side where the upper eaves of the hexagonal brick are located is A, the side where the lower convexity of the hexagonal brick is located is B, and the smooth side without upper eaves and lower convexity is C: a circle around the hexagonal brick can be arranged in ABCABC, or in ABCBAC, BACBAC, BACABC, or even in ABABAB and other arrangements, as long as the plug-in and hook-connection matching methods described in the present invention can be achieved.

[0023] 7) Since hexagonal slope protection bricks are usually hollow structures, when it rains, rainwater will directly rush into the hollow area of ​​the hexagonal slope protection bricks, and then take away the soil in the hollow area of ​​the hexagonal slope protection bricks, which not only causes the vegetation planted in the hollow area to be washed away, but also fails to play the original function of preventing soil erosion. The present invention arranges water-blocking ridges or waterproof ring structures around the hollow area, that is, the through hole, so that whenever rainwater flows through the present invention from top to bottom, most of the rainwater will detour downward due to the obstruction of the water-blocking ridges, thereby maximizing the possibility of rainwater rushing into the hollow area of ​​the hexagonal slope protection bricks, and can improve its soil and water conservation function while ensuring the greening conditions in the gap area, achieving multiple goals at one stroke.

[0024] 8) In actual layout, the slope protection component can have two adjacent hexagonal slope protection bricks with axial symmetry or completely identical structures, provided that they can be plugged in and connected to each other during assembly. Similarly, when extended to the entire slope protection surface, i.e., the slope protection system, the slope protection component can be formed by two hexagonal slope protection bricks, and then the slope protection system can be formed by combining the slope protection components, which can ensure the anti-slip function, anti-sinking function and anti-scouring function of the entire slope protection system, and finally effectively ensure the slope consolidation and slope protection effect of the slope.

[0053] For ease of understanding, here we combine Figure 1-37 The specific structure and working mode of the present invention are further described as follows:

[0054] The present invention uses the block 10 as a carrier, and arranges the upper eaves 11 and the lower protrusions 12 at the corresponding edges of the block 10, so as to form a Figure 1-37 The structure shown. Figure 1-15 is one embodiment of the present invention and its derivative examples, and Figure 16-27 Another embodiment of the present invention and its derivative examples:

[0055] Figure 1-6 10-12 are structures using hexagonal bricks as specific embodiments. On the basis of hollow hexagonal bricks, two groups of adjacent sides are respectively arranged with a group of upper eaves 11 extending outward from the upper part of the side surface and a group of lower protrusions 12 extending outward from the lower part of the side surface. Whenever adjacent hexagonal slope protection bricks are matched with the lower protrusions 12 and the upper eaves 11, the lower protrusions 12 of the adjacent first hexagonal slope protection brick will be inserted into the lower slot a formed by the upper eaves 11 of the current hexagonal slope protection brick, and the upper eaves 11 of the adjacent second hexagonal slope protection brick will be inserted into the upper slot b formed by the lower protrusions 12 of the current hexagonal slope protection brick. Similarly, whenever adjacent hexagonal slope protection bricks cooperate with the two adjacent sides of the lower convexity 12 and the upper convexity 11, the lower convexity 12 of the adjacent third hexagonal slope protection brick will be inserted into the lower slot a formed by the upper convexity 11 of the current hexagonal slope protection brick, and the upper convexity 11 of the adjacent fourth hexagonal slope protection brick will be inserted into the upper slot b formed by the lower convexity 12 of the current hexagonal slope protection brick. Figure 1-16 The conventional smooth surface structure may even be a wavy or serrated side or other special surface shapes. Of course, an upper eave 11 or a lower protrusion 12 may be additionally arranged depending on the situation, which will not be described in detail here.

[0056] On the basis of the above structure, the tail end of the lower slot a formed by the upper eaves 11 can also be closed to form a Figure 7-9 and Figure 13-15 Thus, when the lower protrusion 12 of the corresponding shape of the adjacent first hexagonal slope protection brick is horizontally inserted into the lower slot a of the single-end sealed groove structure, on the basis of the original anti-sinking and anti-warping, the one-way horizontal displacement of the two hexagonal slope protection bricks that match each other can also be limited. When multiple hexagonal slope protection bricks are engaged with each other, a Figure 28-29The slope protection components and slope protection system shown. The horizontal displacement of all hexagonal slope protection bricks in any direction in the entire surface slope protection system will also be limited to each other, that is, all hexagonal slope protection bricks in the entire surface slope protection system are in a fully constrained state, which ultimately ensures the slope consolidation and slope protection effect on the slope.

[0057] Figure 1-15 The structure shown is an axisymmetric structure in which two groups of upper ridges 11 are opposite to each other or two groups of lower ridges 12 are opposite to each other. Figure 16-27 In the invention, another embodiment is disclosed, that is, the entire block 10 is a plane-symmetrical body, the left and right shoulders are both upper rims 11 or lower convexities 12, and the corresponding left and right lower sides are both lower convexities 12 or upper rims 11. When in use, blocks of the same shape can be directly matched to form Figure 30-31 As for the sealing state of the lower slots a, one group of the lower slots a can be sealed separately, or two groups can be sealed symmetrically at the same time. Fig.19 and Fig. 22 The length of the lower protrusion 12 shown has undergone adaptive changes, etc.

[0058] When actually designing the upper eaves 11 and the lower protrusion 12, it should be noted that due to the existence of the lower slot a, it is preferred to use a core-pulling mold to produce during production and processing: when the lower mold is installed and filled with concrete mortar, the upper mold is pressed down to form the present invention, and then the lower slot a at the upper eaves 11 is formed by horizontal core pulling in the same direction, and then the lower mold is vertically pulled upward along the demoulding direction, and then the upper mold is vertically moved upward along the demoulding direction to obtain the hollow hexagonal brick described in the present invention. Of course, Figure 1-13 The spaces of the corresponding slot paths on the adjacent sides do not interfere with each other, but in fact they intersect in the top projection. The reason for the spatial non-interference is that there is a height difference between the two adjacent groups of slots on the adjacent sides. Therefore, when performing demolding and demolding operations, the movement paths between the core mold and other molds will not interfere, and naturally the rapid production of the present invention can be smoothly realized.

[0059] As mentioned above, in actual layout, two adjacent hexagonal slope protection bricks can be as follows: Fig.28 The axisymmetric structure shown in Fig.30 The structures shown are exactly the same, just make sure that they can be plugged in and hooked together during assembly. When a set of slope protection components with an axisymmetric structure form a slope protection system, its layout state refers to Fig.28 shown. Fig.28It can be clearly seen that the lower protrusion 12 of each hexagonal slope protection brick is accurately inserted into the lower slot a formed by the upper eaves 11 of the adjacent hexagonal slope protection brick, or the lower slot a formed by the upper eaves 11 of each hexagonal slope protection brick is accurately sleeved on the lower protrusion 12 of the adjacent hexagonal slope protection brick, and then from point to line, and then from line to surface, finally forming Fig.29 The slope protection system shown. Fig.28 The slope protection system shown in the figure is formed, that is, the left and right, up and down translation and vertical sinking and warping action of each hexagonal slope protection brick will be pinned by the adjacent hexagonal slope protection bricks, thus achieving the reliable working purpose of the entire slope protection system. Figure 30-31 This is the matching method when the structures of two adjacent hexagonal slope protection bricks are completely consistent, for reference.

[0060] As for the shapes of the upper eaves 11 and the lower protrusions 12 between the slope protection components and the corresponding matching slot shapes, they can be set as appropriate according to the site conditions during actual design. Figure 32-37 The six groups of outer shape matching states of the slope protection components shown in the figure are shown in the figure. Figure 32-37 The diagram provided is only a schematic diagram of the normal matching state. The actual design shall prevail during specific production.

[0061] In addition, the present invention also arranges a water-blocking ridge 14 or a waterproof ring structure around the hollow area, that is, the through hole 13. Whenever rainwater flows through the present invention from top to bottom, most of the rainwater will be blocked by the water-blocking ridge 14 and detour downward, thereby maximally reducing the possibility of rainwater rushing into the hollow area of ​​the hexagonal block slope protection brick, while ensuring the greening conditions in the gap area and improving its soil and water conservation function. The specific arrangement position of the water-blocking ridge 14 is as follows: Figure 10-15 and Figure 25-27 As shown. Of course, the through hole 13 here can be a hexagon, or a circle, a diamond or even other adaptive shapes; correspondingly, the waterproof ring structure formed by the water-blocking ridge 14 can also be adaptively changed in shape accordingly, as long as it can achieve its rainwater blocking effect. When there are multiple groups of through holes, the waterproof ring can surround a group of through holes alone, or a group of waterproof rings can be used to surround multiple groups of through holes at the same time, which can be used as appropriate according to the on-site conditions.

[0062] Through the above overall structure, the anti-sinking, anti-slip and anti-scouring functions of the entire slope protection system of the present invention are finally achieved. In the specific design, a mark can also be designed on the top surface of each hexagonal slope protection brick to confirm the direction of the top surface of the hexagonal slope protection brick, facilitate construction, and improve laying efficiency.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention may be implemented in other specific forms without departing from the spirit or essential features of the present invention.
