Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a slope protection device for water conservancy projects. Background Technique

[0002] With the rapid development of the economy and the continuous increase in the demand for water resource utilization, the scale and quantity of water conservancy project construction are also continuously expanding. In the field of water conservancy projects, slope protection is crucial for preventing soil erosion and protecting the dam structure.

[0003] According to the search, the Chinese patent document, publication number: CN211006536U, discloses a slope protection device for water conservancy projects. When water flows downward from the top of the slope, it will be received by the diversion plate. At the same time, the water received in the diversion plate enters the first diversion groove and the second diversion groove through the drainage port, and flows to the bottom of the slope through the first diversion groove and the second diversion groove, so that the water will not pass through the slope surface when flowing from the top of the slope to the bottom of the slope, effectively avoiding the soil erosion carried away when the water flows through the slope surface, and thus realizing the advantage of improving the slope protection performance of the slope protection device for water conservancy projects.

[0004] However, the above slope protection device still has the following deficiencies in the actual application process: when water flows downward from the top of the slope, it will be received by the diversion plate. During this process, rainwater will carry the sediment on the top of the slope, so these sediments will be diverted into the first diversion groove and the second diversion groove together with the rainwater, and then flow to the bottom of the slope through the first diversion groove and the second diversion groove. In this way, the function of effectively preventing soil erosion cannot be achieved. Summary of the Utility Model

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a slope protection device for water conservancy projects.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a slope protection device for water conservancy projects, including a slope body, a catch drain is opened at the top end of the slope body, a filtering component is buried in the catch drain, a plurality of drainage inclined grooves are fixedly connected to the outer surface of the slope body, and a partition board is fixedly connected between the drainage inclined grooves;

[0007] The filtering component includes a front water storage tank, a connecting groove, a rear water storage tank, slot holes, a butt joint pipe, a bottom plate, a suspension rod, a cover plate and drainage holes. Slot holes are respectively and penetratingly opened on one side of the front water storage tank and the connecting groove. One end of the connecting groove and the rear water storage tank is fixedly connected with a butt joint pipe. A bottom plate is arranged inside the front water storage tank, the connecting groove and the rear water storage tank. A suspension rod is fixedly connected to the top surface of the bottom plate. The top surfaces of the front water storage tank, the connecting groove and the rear water storage tank are connected with a cover plate. Drainage holes are penetratingly opened on the front surfaces of the front water storage tank and the rear water storage tank.

[0008] As described above, a front water storage tank, a plurality of connecting tanks, and a rear water storage tank are buried inside the intercepting ditch, and the slot holes and the docking pipes are adapted to each other.

[0009] As described above, embedding grooves are provided at the tops of the front water storage tank, the connecting tanks, and the rear water storage tank. An embedding block is fixedly connected to the lower surface of the cover plate, and a water discharge hole is provided on the top surface of the cover plate.

[0010] As described above, a suspension rod is fixedly connected to the center of the top surface of the bottom plate, and a suspension ring is fixedly connected to the top surface of the suspension rod.

[0011] As described above, one end of the drainage chute close to the top of the slope body is connected to a drainage hole, and a steel bar framework is embedded inside the front water storage tank, the connecting tanks, and the rear water storage tank.

[0012] As described above, fixing piles are fixedly connected to the bottom of the drainage chute, and the fixing piles are buried inside the slope body.

[0013] As described above, a planting area is formed between the drainage chute and the baffle plate. A protection net covers the upper surface of the planting area, and ground nails are connected to the periphery of the protection net.

[0014] Compared with the prior art, the slope protection device for a water conservancy project has the following beneficial effects:

[0015] First, by arranging an intercepting ditch at the top of the slope body and burying a filtering assembly composed of a front water storage tank, connecting tanks, and a rear water storage tank in the present utility model, the sediment carried by rainwater precipitates in the water storage area, greatly reducing the amount of sediment flowing into the lower part of the slope body. When it rains, the rainwater and the sediment brought from the slope top enter the water storage area and will deposit on the bottom plate under the action of gravity and accumulate, thereby filtering out most of the sediment, effectively preventing soil erosion caused by rainwater scouring, and playing a good protective role for the slope body.

[0016] Second, the design of the filtering assembly in the present utility model takes into account the convenience of cleaning and maintenance. The suspension rod at the center of the top surface of the bottom plate and the suspension ring at the top enable the bottom plate to be lifted by using tools through the suspension ring when it is necessary to clean the water storage area after manually opening the cover plate, so as to quickly clean the deposited sediment. If there is still local sediment inside, it can also be manually cleaned. This regular maintenance method can effectively maintain the sediment filtering ability of the filtering assembly, and the cleaning process is simple and convenient, ensuring the long-term stable operation of the entire slope protection device.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-6 shown, the present utility model provides a technical solution: a slope protection device for water conservancy projects.

[0027] According to the overall structure of the device, a slope protection device for water conservancy projects includes a slope body 1, an intercepting ditch 2 is opened at the top of the slope body 1, a filter assembly 3 is buried in the intercepting ditch 2, a plurality of drainage chutes 4 are fixedly connected to the outer surface of the slope body 1, and a blocking plate 5 is fixedly connected between the drainage chutes 4;

[0028] The filter assembly 3 includes a front water storage tank 301, a connecting tank 302, a rear water storage tank 303, a slot hole 304, a butt joint 305, a bottom plate 306, a suspension rod 307, a cover plate 308 and a drainage hole 309. The slot hole 304 is penetrated through one side of the front water storage tank 301 and the connecting tank 302, and the butt joint 305 is fixedly connected to one end of the connecting tank 302 and the rear water storage tank 303. The bottom plate 306 is arranged inside the front water storage tank 301, the connecting tank 302 and the rear water storage tank 303, and the top surface of the bottom plate 306 is fixedly connected to the suspension rod 307. The top surfaces of the front water storage tank 301, the connecting tank 302 and the rear water storage tank 303 are connected to the cover plate 308, and the front surfaces of the front water storage tank 301 and the rear water storage tank 303 are penetrated with drainage holes 309.

[0029] like Figures 1-4 As shown, a front water storage tank 301, a plurality of connecting tanks 302 and a rear water storage tank 303 are buried inside the intercepting ditch 2, and the slot hole 304 and the butt-joint pipe 305 are adapted to each other.

[0030] The tops of the front water storage tank 301 , the connecting tank 302 and the rear water storage tank 303 are all provided with embedded grooves, the lower surface of the cover plate 308 is fixedly connected with an embedded block, and the top surface of the cover plate 308 is provided with a water discharge hole.

[0031] A water intercepting ditch 2 is opened at the top of the slope 1 for burying the filter assembly 3, and then the slope of the slope 1 is leveled, and a front water storage tank 301, a plurality of connecting grooves 302 and a rear water storage tank 303 are successively buried in the water intercepting ditch 2, and the butt joint 305 can be inserted into the slot hole 304, so that a front water storage tank 301, a plurality of connecting grooves 302 and a rear water storage tank 303 can be connected into a whole through the butt joint 305 and the slot hole 304, and then the tops of the front water storage tank 301, the plurality of connecting grooves 302 and the rear water storage tank 303 are covered. The cover plate 308, when it rains, rainwater will fall into the front water storage tank 301, multiple connecting grooves 302 and a rear water storage tank 303 through the drainage holes opened on the cover plate 308. Since the front water storage tank 301, the connecting grooves 302 and the rear water storage tank 303 are connected to form a water storage area through the docking pipe 305 and the slot hole 304, the rainwater and the mud and sand carried from the top of the slope will enter the water storage area, and the mud and sand will be deposited on the bottom plate 306 under the action of gravity, thereby filtering out most of the mud and sand, which is helpful to prevent the mud and sand from being washed into the bottom of the slope 1 by rainwater.

[0032] like Figure 3 As shown, a suspension rod 307 is fixedly connected to the center of the top surface of the bottom plate 306 , and a suspension ring is fixedly connected to the top surface of the suspension rod 307 .

[0033] By opening a water drainage hole in the cover plate 308, large particle impurities such as gravel can be prevented from entering the water storage area. When it is necessary to clean the water storage area, after manually opening the cover plate 308, since a lifting ring is provided at the top of the hanging rod 307, a tool can be passed through the lifting ring and then lifted, so that the bottom plate 306 can be lifted, and then the sediment deposited on the bottom plate 306 can be quickly cleaned. If there is still local sediment remaining inside the front water storage tank 301, the connecting tank 302 and the rear water storage tank 303, it can be manually cleaned. In this way, regular maintenance can effectively maintain the ability of the filtering component 3 to filter sediment, and the cleaning process is also simple and convenient.

[0034] As Figures 1-2 shown, one end of the drainage chute 4 close to the top of the slope body 1 is connected to the drainage hole 309, and a steel bar framework 6 is embedded inside the front water storage tank 301, the connecting tank 302 and the rear water storage tank 303.

[0035] After sediment is precipitated in the water storage area formed by the front water storage tank 301, multiple connecting tanks 302 and the rear water storage tank 303, as the water level rises, the water will finally flow out from the drainage hole 309 and enter the inside of the drainage chute 4, and the water is guided to the lower part of the slope body 1 through the drainage chute 4 to achieve drainage. The front water storage tank 301, the connecting tank 302 and the rear water storage tank 303 are all made of cement poured by a formwork, and a steel bar framework 6 is added inside the formwork. In this way, after the front water storage tank 301, the connecting tank 302 and the rear water storage tank 303 are formed, their strength can be greatly improved.

[0036] As Figure 5 shown, the bottom of the drainage chute 4 is fixedly connected to a fixing pile 7, and the fixing pile 7 is buried inside the slope body 1.

[0037] By opening a hole on the slope of the slope body 1 and then burying the fixing pile 7, connecting a steel reinforcement cage through the fixing pile 7, and then pouring and forming the drainage chute 4 by cooperating with a formwork on the outer surface of the steel reinforcement cage, the formed drainage chute 4 has very strong grip force, strengthening the connection strength between the drainage chute 4 and the slope body 1.

[0038] As Figures 1-2 and Figure 6 shown, a planting area is formed between the drainage chute 4 and the partition board 5, the upper surface of the planting area is covered with a protection net 8, and the periphery of the protection net 8 is connected to ground nails 9.

[0039] By pouring partition boards 5 between several drainage chutes 4 to strengthen the connection between each drainage chute 4, and then planting lawns in the planting area. Since most of the soil is still exposed when the lawn has not grown up, by setting the protection net 8 to cover the planting area, most of the soil erosion is effectively avoided. By setting the ground nails 9, they can be inserted into the soil to fix the protection net 8.

[0040] Working principle: First, a catch drain 2 is excavated at the top of the slope body 1, and then the slope surface of the slope body 1 is leveled. A front water storage tank 301, multiple connecting tanks 302, and a rear water storage tank 303 are successively buried inside the catch drain 2. The butt joint pipe 305 can be inserted into the slot hole 304, so that a front water storage tank 301, multiple connecting tanks 302, and a rear water storage tank 303 are connected to form a temporary water storage area. Fixing piles 7 are drilled and buried on the slope surface, and the steel reinforcement cages are connected through the fixing piles 7. Then, a drainage chute 4 is formed by pouring concrete in cooperation with a formwork on the outer surface of the steel reinforcement cages. Subsequently, a partition board 5 is poured between several drainage chutes 4. Similarly, the bottom of the partition board 5 also has fixing piles 7 and steel reinforcement cages inside. Turf is planted in the planting area formed between the partition board 5 and the drainage chute 4, and a protective net 8 is covered on the turf, which is beneficial to further retaining soil and water. The protective net 8 is fixed by driving ground nails 9 into the soil; in rainy weather, rainwater will fall into the interiors of the front water storage tank 301, multiple connecting tanks 302, and a rear water storage tank 303 through the water discharge holes opened on the cover plate 308. Since the front water storage tank 301, the connecting tank 302, and the rear water storage tank 303 are connected through the butt joint pipe 305 and the slot hole 304 to form a water storage area, the rainwater and the sediment carried from the top of the slope will enter the water storage area, and the sediment will settle on the bottom plate 306 under the action of gravity and accumulate. In this way, most of the sediment is filtered out, which is beneficial to preventing the sediment from being washed into the lower part of the slope body 1 by the rainwater. As the water level rises, the water will finally flow out from the drain hole 309 and enter the interior of the drainage chute 4, and the water is guided to the lower part of the slope body 1 through the drainage chute 4 to achieve drainage; regularly, after manually opening the cover plate 308, a tool can be put through the hanging ring of the hanging rod 307 and then lifted, so that the bottom plate 306 can be lifted, and then the sediment deposited on the bottom plate 306 can be quickly cleaned up. If there is still local sediment remaining in the interiors of the front water storage tank 301, the connecting tank 302, and the rear water storage tank 303, it can be manually cleaned up.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
