Description

Technical Field

[0001] This invention relates to the technical field of slope protection devices, and more specifically to a slope protection brick for vegetation buffer zone repair. Background Technology

[0002] River dredging refers to the use of mechanical equipment to agitate silt deposited on the riverbed, creating a turbid watery substance that is then carried away by the river current, thus clearing the waterway. After dredging, vegetation is often planted to enhance the water's water conservation capacity and minimize soil erosion. In the initial stages of planting, vegetation often has limited protective capabilities, requiring the use of retaining walls to protect it, reduce sediment ingress into the river, and ensure successful vegetation growth.

[0003] Chinese patent (patent publication number: CN213173581U) discloses a slope protection brick for restoring vegetation buffer zones after river dredging. The brick includes a main body, with anti-slip blocks fixedly installed on the top. Limiting blocks are fixedly installed on the top of the rear end and the bottom of the front end of the main body. A waterway is formed on the outer periphery of the top of the main body, and protective covers are fixedly installed on the left and right ends of the top periphery. Drainage holes are formed in the middle of both sides and the middle of the bottom of the main body, and a drainage chamber is formed in the middle of the interior of the main body. This slope protection brick for restoring vegetation buffer zones after river dredging achieves good slope protection by incorporating a main body, fixing strips, and limiting blocks. The main body adopts a Z-shaped structure, allowing multiple main bodies to overlap and be installed longitudinally with the limiting blocks. Laterally, they are engaged with the fixing strips via slots. The lateral and longitudinal slope protection bricks work together effectively, resulting in good overall integrity and strong slope protection capacity.

[0004] Another Chinese patent (patent publication number: CN111305239B) discloses a slope protection brick and a slope protection drainage system composed of the same. The slope protection brick is a hollow hexagonal brick body, and each of the six sides is provided with an upper embedding opening and a lower embedding opening. One end of the "L"-shaped seepage baffle is provided with a groove that matches the upper embedding opening, and the other end of the "L"-shaped seepage baffle is a seepage baffle. One side of the water-retaining straight plate is provided with a groove that matches the lower embedding opening. The water-retaining straight plates are all connected by fitting together with regular triangular prism connecting plates. There are two drainage connection methods between the slope protection bricks: a primary drainage system and a secondary drainage system. The primary drainage system is composed of "L"-shaped seepage baffles, water-retaining straight plates, and regular triangular prism connecting plates. The secondary drainage system is composed of "L"-shaped seepage baffles, water-retaining straight plates, regular triangular prism connecting plates, and rhomboid drainage plates.

[0005] While the aforementioned slope protection bricks used for restoring vegetation buffer zones after river dredging can effectively protect slopes, they require additional fixing strips for installation, making transportation and installation cumbersome. Furthermore, depending on the region, specific components need to be customized or processed, increasing construction costs. Similarly, slope protection bricks used in mountain slope drainage systems also require splicing, as they necessitate the assembly of slabs with different shapes and structures, significantly increasing construction difficulty and efficiency, and also creating transportation challenges. Summary of the Invention

[0006] The present invention provides a slope protection brick for vegetation buffer zone repair, which solves the problem of high construction cost of existing slope protection bricks.

[0007] To achieve the above objectives, the following technical solution is adopted:

[0008] A slope protection brick for vegetation buffer zone restoration includes a regular hexagonal brick body with a hollow internal structure. Each side wall of the brick body has a water inlet hole. The top and bottom of the brick body have funnel-shaped drainage hoppers. The side walls of each drainage hopper are made of permeable material. Each drainage hopper contains a sealing block. The sealing block and the brick body share multiple interconnected inverted trapezoidal grooves. Each inverted trapezoidal groove contains a limiting block. A sliding cylinder connects two drainage hoppers. Two sliding plates are slidably and sealingly connected within the sliding cylinder. A spring connects the two sliding plates. Both ends of the sliding cylinder are threaded with limiting rings located outside the corresponding sliding plates. Drainage outlets are symmetrically located on both sides of the sliding cylinder.

[0009] Preferably, a filter screen is connected between the side wall of the brick body and the slide cylinder, and one end of the filter screen covers the edge of the drain outlet.

[0010] With the above setup, sludge can be collected using a filter screen, preventing it from flowing back into the river.

[0011] Preferably, the slide tube has multiple vent holes facing the filter screen.

[0012] With the above setup, when the slide moves along the center of the slide tube driven by rainwater and mud, it can blow air from inside the slide tube to the filter screen, thereby clearing some of the blocked filter screen holes and helping to maintain the filter screen's effectiveness.

[0013] Preferably, the thickness of the slide plate is the same as the height of the drain hopper.

[0014] With the above settings, the drainage rate can be adjusted according to the rainfall in different regions and seasons. Under normal conditions, only one sealing block needs to be removed to collect sludge and drain rainwater. When it is necessary to increase the drainage capacity, two sealing blocks on some or all of the slope protection bricks can be removed at the same time when laying the slope protection bricks, and a limiting ring can be removed at the same time to keep the upper slider always open.

[0015] Preferably, the side of the slide plate facing the drain hopper has a structure that is high in the middle and low at the edges.

[0016] The above setup facilitates the accumulation of sludge on both sides of the slide plate, which helps to quickly flush the sludge into the filter screen with the help of rainwater.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This solution utilizes a filter screen to collect sludge, while the internal space of the brick body facilitates sludge sedimentation, further reducing the possibility of sludge flowing back into the river. The internal space also allows for the collection of some rainwater, increasing the weight of the slope protection bricks and contributing to the stability of multiple bricks when combined. This slope protection brick system is primarily used in areas prone to soil erosion, such as rivers and lakes; after installation, the entire area appears clean and aesthetically pleasing.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figure 1-5 As shown, a slope protection brick for vegetation buffer zone restoration includes a regular hexagonal brick body 1 with a hollow internal structure. Each side wall of the brick body 1 has a water inlet hole 2 at its center, allowing multiple slope protection bricks to connect and communicate with each other after installation, facilitating rapid drainage. The top and bottom centers of the brick body 1 each have a funnel-shaped drainage hopper 3. The side walls of each drainage hopper 3 are made of permeable material; in this embodiment, porous concrete is used to facilitate rapid drainage of rainwater from the drainage hopper 3 and to retain sludge within it. Each drainage hopper 3 has a sealing block 4 that matches its shape. The sealing block 4 and the brick body 1 together have six interconnected inverted trapezoidal grooves, equidistantly distributed circumferentially at the center of the corresponding side length on the top or bottom. Each inverted trapezoidal groove is fitted with a limiting block 5, which allows for the connection and positioning of two slope protection bricks.

[0027] A sliding cylinder 6 located inside the brick body 1 connects the two drainage hoppers 3. Two sliding plates 7 are slidably and sealed within the sliding cylinder 6. The thickness of each sliding plate 7 is the same as the height of the drainage hopper 3. Each sliding plate 7 has a structure with a higher center and lower edges on the side facing the drainage hopper 3, allowing sludge to slide easily to both sides of the sliding plate 7 under the impact of rainwater, thus improving sludge collection efficiency. A spring 8 connects the two sliding plates 7. Limiting rings 9 are threaded to both ends of the sliding cylinder 6 and located outside the corresponding sliding plate 7. The limiting rings 9 prevent the sliding plate 7 from sliding out of the sliding cylinder 6. Drainage outlets 10 are symmetrically provided on the front and rear sides of both the upper and lower ends of the sliding cylinder 6. The bottom of the drainage outlets 10 is flush with the bottom of the sliding plates 7. A filter screen 11 is connected between the side wall of the brick body 1 and the drainage outlets 10. The filter screen 11 is arc-shaped and completely covers the edge of the drainage outlets 10, allowing the sludge to fall completely onto the filter screen 11 under the impact of rainwater. A ventilation hole 12 is provided in the middle of the slide cylinder 6. Three ventilation holes 12 are distributed at intervals on the slide cylinder 6, and all three ventilation holes 12 are located within the lateral width range of the filter screen 11. Each ventilation hole 12 adopts a Y-shape, and the two air outlets of the ventilation hole 12 face the corresponding filter screen 11.

[0028] The working process of this solution is as follows:

[0029] When a single slope protection brick is not installed, the spring 8 is compressed, causing the two sliding plates 7 to abut against the corresponding limiting rings 9, and the sealing block 4 is fixed in the drainage hopper 3 under the action of the limiting block 5. This slope protection brick does not require other auxiliary fixing parts during laying, which facilitates loading and transportation and reduces related transportation costs. At the same time, there is no need to distinguish between the front and back sides during installation. Only one limiting block 5 on the abutting side of two adjacent slope protection bricks needs to be removed, and the other limiting block 5 can be snapped into the inverted trapezoidal groove connecting the two slope protection bricks to achieve connection and limiting of the two slope protection bricks. The operation is simple and convenient, reduces the difficulty of installation, and helps to improve construction efficiency. After installation, the overall appearance is simple and beautiful.

[0030] When multiple slope protection bricks are connected and positioned, the sealing blocks 4 on the upper side of all slope protection bricks are removed. Under the flushing of rainwater, sludge flows through the surface of the slope protection bricks into the drainage hopper 3. Eventually, the sludge gradually accumulates on both sides of the sliding plate 7. The funnel-shaped drainage hopper 3 can efficiently collect and separate the sludge and rainwater. At the same time, because the side wall of the drainage hopper 3 is made of porous concrete, rainwater passing through the side wall of the drainage hopper 3 can quickly leak into the interior of the slope protection bricks, thus collecting rainwater through the internal space of the slope protection bricks. When the rainwater submerges the water inlet 2 in the middle of the slope protection brick, it can be quickly diverted to the interior of other slope protection bricks through multiple water inlet holes 2, and finally discharged through the water inlet 2 of the slope protection brick located on the outer side.

[0031] As the weight of the sludge on the slide plate 7 gradually increases, the slide plate 7 can be pressed down further. Eventually, rainwater pushes the sludge from the drain outlet 10 into the filter screen 11, where the sludge is collected and rainwater passes through. During the downward pressing of the slide plate 7, it pushes the air between the two slide plates 7 through the vent 12 towards the two filter screens 11, helping to clear some of the clogged mesh. When the impact force of the rainwater exceeds the elastic force of the spring 8 on the slide plate 7, it can also push the slide plate 7 downwards, further increasing the water absorption effect through the drain outlet 10.

[0032] When the sludge enters the filter screen 11 through the drain outlet 10, some of the smaller sludge particles may still pass through the filter and enter the slope protection bricks. At this time, the internal space of the slope protection bricks can buffer and settle the small sludge particles, allowing them to settle and collect at the bottom of the slope protection bricks, further preventing the sludge from entering the river.

[0033] During the installation of slope protection bricks, the drainage efficiency of multiple slope protection bricks can be adjusted according to the rainfall conditions in different regions and seasons. This is achieved by simultaneously removing the lower limiting ring 9 and sealing block 4 of some slope protection bricks along with the upper sealing block 4. This causes the sliding plate 7 inside the slope protection brick with the two sealing blocks 4 removed to move downwards, thus fully opening the drain outlet 10 on the sliding cylinder 6. Simultaneously, a certain gap exists between the lower drain hopper 3 sidewall and the sliding plate 7. When a large amount of rainwater enters the slope protection brick through the upper drain hopper 3 sidewall and drain outlet 10, the rainwater can quickly flow out through the lower slope protection brick, accelerating drainage efficiency. Furthermore, when the water level inside the slope protection brick is lower than the inlet hole 2, it can assist the drainage of the six adjacent slope protection bricks. Therefore, after installation, the drainage capacity of this slope protection brick can be adjusted according to actual needs, further expanding the application range of this solution and providing excellent protection for the restoration of vegetation buffer zones.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
