Description

Technical Field

[0001] The utility model relates to a roadbed slope protection technology, in particular to a slope protection brick. Background Art

[0002] The slope of the fill roadbed on the highway is generally 1:1.5, except for the case of artificial stone stacking. The slope of the excavation is generally determined according to the geological conditions. The soil or fully weathered, strongly weathered slope should not be steeper than 1:1.5 (about 33.69°).

[0003] The existing slope protection forms are: 1. Arch frame slope protection, the arch frame forms a water flow channel to prevent rainwater erosion, and the soil inside the arch is planted with grass to beautify the environment; 2. Block slope protection: divided into hollow hexagonal blocks and solid hexagonal blocks, mainly used for highway slope protection and dam slope protection bricks, other forms of slope protection bricks are rarely used.

[0004] The existing slope protection forms can generally achieve good slope protection effects by protecting and greening the slopes. However, in severe and extreme weather conditions such as sudden rainfall, strong winds with rain, and continuous rain, some slopes become unstable and collapse and landslides occur.

[0005] The erosion of rainwater causes the loss of shallow soil on the slope, slope collapse, local depression, or soil expansion, which is one of the main factors of slope failure.

[0006] Although the arch frame can drain some rainwater, 60-80% of the rainwater seeps into the soil. The shallow soil is lost with the rainwater, forming a slope depression. The infiltration of rainwater increases the deadweight of the soil, reduces cohesion and strength, and causes the slope to sink, fracture, deform and collapse. The arch frame will also fracture, deform and collapse along with the slope, losing its original function.

[0007] The soil in the holes of the hollow hexagonal blocks is easily washed away by rainwater, causing the slope to sink and become unstable. Rainwater penetrates into the slope, reducing the shear resistance of the soil and increasing the pressure of the saturated soil, making the slope prone to slippage and collapse.

[0008] Solid hexagonal blocks are used to protect slopes. From the outside, their strength and rigidity meet the design requirements, and rainwater cannot enter the soil from the protective layer. However, rainwater slowly seeps into the edges of the overlapping protective layer, foundation settlement, and local cracks in the protective layer, causing the slope soil to expand, sink or collapse, resulting in slope damage.

[0009] In the process of implementing the roadbed slope protection project, the inventor believes that the existing slope protection blocks do not have drainage function. If an anti-seepage drainage slope protection brick can be provided to prevent a drop of rainwater from entering the soil, the impact of rainwater on the slope soil can be fundamentally solved, thereby solving the problem of slope damage.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] The utility model provides an anti-seepage drainage slope protection brick, which can prevent a drop of rainwater from entering the slope soil, allowing the rainwater on the slope to be quickly drained away, thereby preventing the slope from being damaged by rainwater scouring. On this basis, a greening drainage brick type is also designed that can intercept a small part of the rainwater for green plants and allow most of the remaining rainwater to be quickly drained away, which can prevent the slope from being damaged by rainwater scouring.

[0038] In order to achieve the purpose of drainage and anti-seepage, the utility model introduces the tile surface drainage structure into the brick body, and at the same time realizes the interlocking of the anti-seepage drainage bricks on the slope surface without affecting the anti-seepage drainage, forming an integral waterproof slope surface, and preventing the anti-seepage drainage bricks from shifting on the slope surface. The anti-seepage slope protection brick of the utility model is made by concrete block forming technology, with a deadweight of about 50 kilograms, and can be stable in deadweight.

[0039] The following is a detailed description of various embodiments of the present invention.

[0040] Embodiment 1

[0041] Combined with reference Figures 1 to 3 The utility model comprises a brick body 1, a guide groove 2 arranged on the top surface of the brick body, a first locking structure 3 located on the upper side of the brick body, a second locking structure 4 located on the lower side of the brick body, an upper clamping edge 5 located on the left side of the brick body, and a lower clamping edge 6 located on the right side of the brick body.

[0042] Among them, the above-mentioned brick structure forms a field-shaped coordination when paving the slope, wherein the horizontal bricks are in the same layer, the upper clamping edges 5 and the lower clamping edges 6 of two adjacent horizontal bricks overlap, and the longitudinal bricks are in different layers, and the lower bottom of the upper brick body 1 overlaps the upper top of the lower brick body to form an overlapping area.

[0043] The first locking structure 3 is a locking groove, and the second locking structure 4 is a locking tooth, which is an embedded structure hidden under the top surface of the brick body.

[0044] The first locking structure 3 and the second locking structure 4 of the two adjacent brick bodies in the upper and lower layers are matched, and the matched locking structures are hidden inside the overlapping area.

[0045] After the bricks are laid in a field shape, the lower end of the guide groove 2 of the upper brick body is connected with the guide groove of the lower brick body, so that drainage is achieved through the guide groove 2 on the brick surface.

[0046] The first locking structure and the second locking structure are both dovetail structures, so that the brick interlocking structure formed in this way will not loosen in both directions of the slope.

[0047] Among them, the first locking structure is a dovetail groove sunken downward from the top surface of the brick body. The dovetail groove is a blind groove, and the bottom surface 3a of the groove is flush with or higher than the bottom of the guide groove 2, and the dovetail groove is connected to the guide groove 2 for rainwater to flow downward along the guide groove.

[0048] In this embodiment, the upper and lower edges of two adjacent brick bodies in the same layer are overlapped together, and rainwater seeps into the joint between the two and flows into the diversion groove and the brick surface along the lower edge. Moreover, the dovetail groove and the diversion groove are connected, so that the upper brick body overlapped on the top area (dovetail groove) of the lower brick body can be drained downward through the groove bottom surface of the dovetail groove and the diversion groove, and then the slope protection bricks of this embodiment do not allow a drop of rainwater to seep into the soil under the brick body when building the slope, achieving the purpose of 100% anti-seepage.

[0049] Embodiment 2

[0050] Combined with reference Figures 4 to 7 The anti-seepage drainage brick of this embodiment is suitable for laying on a slope with a slope ratio of 1:1.5, and includes a brick body 1, a guide groove 2 arranged on the edge of the top surface of the brick body, a first locking structure 3 located on the upper side of the brick body, a second locking structure 4 located on the lower side of the brick body, an upper clamping edge 5 located on the left side of the brick body, a lower clamping edge 6 located on the right side of the brick body, and an upper overlapping edge 7 located on the lower side of the brick body.

[0051] The upper overlapping edge 7 overlaps with the top of the lower brick body, and the upper overlapping edge 7 covers and exceeds the first locking structure 3 area of ​​the lower brick body, so that rainwater can flow downward and pass over the first locking structure 3.

[0052] The first locking structure 3 is a locking groove, and the second locking structure 4 is a locking tooth. The locking groove is a through groove that penetrates the entire thickness of the brick body.

[0053] In addition to the anti-seepage function, the upper overlap edge set on the lower side of the brick body also has the following effects:

[0054] The first locking structure 3 can be a through groove or a blind groove recessed from top to bottom. At the same time, the top surface of the locking groove can be high or low, the locking groove can be wide or narrow, deep or shallow, and the locking groove can be connected to the guide groove 2 or not, and the design is flexible and free.

[0055] In this embodiment, the bottom of the guide groove 2 is parallel to the bottom surface 1a of the brick body. In other embodiments, the groove surface of the guide groove 2 may be inclined from top to bottom, with the upper part being higher and the lower part being lower.

[0056] The anti-seepage drainage bricks of this embodiment are laid in a field shape when laid on a slope, that is, the horizontal bricks are in the same layer, and the vertical bricks are in the same row.

[0057] Because the upper clamping edge 5 and the lower clamping edge 6 of two adjacent brick bodies on the same layer are overlapped together, rainwater seeps into the joint between the two and flows along the lower clamping edge into the guide groove and the brick surface. The upper overlap edge 7 on the lower side of the upper brick body shields the brick body interlocking structure to prevent rainwater from infiltrating.

[0058] Thus, the slope protection bricks of this embodiment do not allow a drop of rainwater to penetrate into the slope soil at the bottom of the brick body when the slope is built, achieving the purpose of 100% anti-seepage. However, for the purpose of planting grass, one or more grass planting wells 8 are formed on the brick surface on the side of the diversion groove to intercept a part of the rainwater, and the well mouth 8a of the grass planting well protrudes from the surrounding brick surface.

[0059] This embodiment can intercept part of the rainwater in a targeted manner, for example, 90% of the rainwater is discharged downward, and about 10% of the rainwater is intercepted and used for the grass planting well, thus forming a green drainage brick type. The well mouth of the grass planting well protrudes from the surrounding brick surface, and the rainwater on the surrounding brick surface will not flow from the brick body surface into the grass planting well, but will be discharged along the diversion groove. The rainwater area intercepted by the grass planting well is limited to the grass planting well itself.

[0060] Embodiment 3

[0061] Reference Figures 8 to 11 The difference between this embodiment and the second embodiment is that, 1. the shape of the grass planting well is changed; 2. the first locking structure 3 is a locking tooth, and the second locking structure 4 is a locking groove, which is an embedded structure, specifically formed by the bottom surface 1a of the brick body being recessed into the brick body.

[0062] Embodiment 4

[0063] Reference Fig.12The difference between this embodiment and the third embodiment is that the first locking structure 3 is a locking tooth, and the locking tooth extends from the top surface of the brick body to the inside of the brick body. The thickness of the locking tooth is less than the thickness of the brick body, and the area around the bottom of the locking tooth is a table surface 3b.

[0064] It can be seen from the combination of the second to fourth embodiments that after adopting the upper overlapping edge 7, the first locking structure 3 and the second locking structure 4 only need to form locking teeth and locking grooves for each other, and the structural design of the locking teeth and locking grooves is flexible and free.

[0065] In the above-mentioned embodiment, one guide groove is arranged at the edge, and in other embodiments, it may be a pair of guide grooves arranged at the edge, or it may be a large-area guide groove arranged in the center.

[0066] In the above embodiment, the locking groove and the locking tooth are dovetail-shaped structures. In other embodiments, the two may also be T-shaped structures.

[0067] In the above embodiment, the lower clamp edge is designed with a protruding water-blocking ridge / ridge 6a (see Figure 1 ), which can prevent rainwater from overflowing. In other embodiments, the common anti-seepage card edge structure on the roof tile can also be used.

[0068] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
