Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy bank slope protection, and in particular to a river bank slope collapse protection system and a protection method. Background Art

[0002] Bank collapse refers to the deformation phenomenon such as collapse or landslide of river bank slopes due to the interaction of water flow and sediment movement with riverbed boundary conditions. In recent years, due to the dual influence of changes in natural conditions, soil and water conservation, reservoir operation and other human activities, the water and sediment conditions of the river have changed significantly, causing long-term, large-scale scouring of the river and local river flow adjustments. For example, the bank collapse in the middle and lower reaches of the Yangtze River continues to occur frequently, which in turn has an adverse impact on flood control, shipping, ecology and other aspects. The river bank collapse protection system refers to the structure built to protect the stability of the river bank slope, reduce the impact of river water, and protect nearby land from scouring and erosion. It is of great significance to the control and mitigation of bank collapse.

[0003] During the construction of the bank slope, earthwork excavation is first carried out according to the design requirements, and the soil and rocks that do not meet the requirements are excavated. The excavation depth and slope are strictly controlled to avoid over-excavation or under-excavation; the excavated foundation is leveled and compacted to ensure that the foundation is solid and stable. For weak foundations or poor geological conditions, corresponding foundation treatment measures such as replacement and reinforcement are required. Stone masonry or concrete pouring is carried out according to the design requirements. Drainage facilities such as drainage ditches and drainage pipes are set up according to the needs of the project to ensure that the water inside the bank slope can be discharged in time.

[0004] After the slope construction is completed, the slope surface is generally exposed, or plants are transplanted on the slope for ecological restoration. However, since the slope surface is initially formed, it takes some time for the new plants to grow and the plants to solidify the soil. During this period, bank collapse is prone to occur. Summary of the invention

[0005] The purpose of the present invention is to overcome the above technical deficiencies, provide a river bank collapse protection system and protection method, and solve the technical problem that newly built slopes are prone to bank collapse in the prior art.

[0083] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0084] like Figures 1 to 15 As shown, the present invention provides a river bank collapse protection system, including a bank 1, a plurality of gabion structures 2, and a plurality of anti-scour structures 3. The bank 1 is provided with a plurality of inclined surfaces 1a and a plurality of planes 1b on one side close to the water flow, and the plurality of planes 1b and the plurality of inclined surfaces 1a are alternately distributed along the direction close to the bottom of the bank 1; the plurality of gabion structures 2 are respectively arranged on the plurality of planes 1b, and the gabion structures 2 include a mesh box 21 and a rock layer 22, the mesh box 21 is arranged on the plane 1b, and the rock layer 22 is built in the mesh box 21; the plurality of anti-scour structures 3 are respectively arranged on the plurality of inclined surfaces 1a, and the anti-scour structures 3 include a reinforcement net 31, an anti- A protective component 32 and multiple connecting components 33, the reinforcement net 31 fits the inclined surface 1a and is connected to the slope 1, the protective component 32 is arranged on the side of the reinforcement net 31 deviating from the inclined surface 1a, the protective component 32 includes two connected protective membranes 321, and multiple water storage chambers 321a are formed between the two protective membranes 321. The two protective membranes 321 are both provided with drip holes connected to the water storage chambers 321a, and the two protective membranes 321 are also provided with fixing holes. The connecting component 33 abuts the protective membranes 321, and part of the connecting component 33 passes through the two protective membranes 321 through the fixing holes and is detachably connected to the reinforcement net 31.

[0085] Specifically, a large-size slope 1a of the bank slope 1 is divided into multiple slopes 1a and planes 1b by setting multiple slopes 1a and planes 1b on the side of the bank slope 1 close to the water flow, and the multiple planes 1b and the multiple slopes 1a are alternately distributed in the direction close to the bottom of the bank slope 1. When a certain slope 1a collapses, the plane 1b below the slope 1a can slow down and block the collapse, so as to avoid the collapse of the entire slope 1a when a single large slope 1a is set; the mesh box 21 is set on the plane 1b, and the rock layer 22 is set in the mesh box 21. The existence of the rock layer 22 can prevent rainwater from directly scouring the soil. The mesh box 21 fixes the rock layer 22 together and is arranged on the plane 1b, so as to reinforce the plane 1b. The reinforced gabion structure 2 can withstand soil displacement and water scouring; the combined use of the gabion structure 2 and the anti-scouring structure 3 significantly enhances the overall stability of the bank slope 1, especially at the junction of the slope 1a and the plane 1b, the gabion structure 2 effectively prevents the formation of soil gullies;

[0086] By setting the protection component 32, the reinforcement net 31 in the protection component 32 can reinforce the soil on the slope 1a as a whole to avoid bank collapse. By setting two protection films 321, the protection films 321 can isolate the reinforcement net 31 and dripping rainwater to prevent rainwater from scouring the soil in the reinforcement net 31 and causing soil erosion; the water storage cavity 321a between the protection films 321 can store and slowly release rainwater to provide sufficient moisture for new vegetation, which is helpful for the growth of vegetation and the solidification of soil, thereby promoting ecological recovery, so that vegetation can have enough time to solidify the soil. At the same time, due to the protection Rainwater is stored in the water storage cavity 321a between the membranes 321, and the rainwater can increase the weight of the protective membrane 321, so that the protective membrane 321 is attached to the reinforcement net 31 to prevent the protective membrane 321 from floating; the connecting component 33 connects the two protective membranes 321 with the reinforcement net 31 through the fixing hole to ensure the stability and maintainability of the protective component 32; when the vegetation grows to meet the expected requirements, the connection between the connecting component 33 and the reinforcement net 31 is released, the two protective membranes 321 are removed from the reinforcement net 31, the two protective membranes 321 are reused, and the vegetation under the protective membrane 321 can grow normally.

[0087] It should be understood that the reinforcement mesh 31 can be fixed in the soil by anchor rods, soil nails, expansion bolts, etc.

[0088] It should be understood that the net box 21 can be a box body 211 with a hollow interior and an open end, or a box body 211 with an end cover provided at the open end. Figure 3 and Figure 4As shown, the mesh box 21 includes a box body 211, a plurality of spacers 212 and an end cover 213. The interior of the box body 211 is hollow and one side is open. A plurality of spacers 212 are inserted into the box body 211 at intervals along the length direction of the box body 211. The end cover 213 is arranged relative to the opening of the box body 211 and one side is connected to the box body 211. The box body 211, the plurality of spacers 212 and the end cover 213 are all mesh structures.

[0089] Specifically, the box 211 is first set on the plane 1b, and then the rocks are sequentially filled in multiple grids of the box 211. After the filling is completed, the spacer 212 is connected and reinforced with the box 211, and the end cover 213 is set on the box 211, and the end cover 213 and the box 211 are connected. After the connection is completed, the rock layer 22 is fixed in the box 211. It should be understood that the spacer 212 and the box 211, and the end cover 213 and the box 211 can be tied with steel wires, ropes, etc.

[0090] The inside of the net box 21 is hollow and one side is open, which is convenient for loading rocks or other fillers. The box body 211 adopts a mesh structure, which not only ensures the stability of the structure, but also allows moderate exchange of water and soil particles, which is conducive to ecological restoration; the mesh structure of the box body 211 and the spacer 212 are convenient for filling and assembly during construction, improving construction efficiency. At the same time, this design is also convenient for later maintenance and replacement; the combined design of the box body 211 and the spacer 212 significantly enhances the overall stability of the gabion structure 2, enabling it to resist large water scouring and erosion. In addition, the multiple small storage spaces formed by the spacer 212 help to retain soil and moisture, further improving stability.

[0091] It should be understood that the rock layer 22 is composed of gradations of rocks of different sizes.

[0092] like Figure 1 and Figure 2 As shown, in one embodiment, the gabion structure 2 further includes a geotextile 23 and a soil layer 24 . The geotextile 23 is arranged between the mesh box 21 and the plane 1 b , and the soil layer 24 is arranged between the geotextile 23 and the mesh box 21 .

[0093] The geotextile 23 is arranged between the mesh box 21 and the plane 1b, which can effectively prevent soil particles from overflowing from the gaps of the mesh box 21, thereby significantly reducing the risk of soil loss. The geotextile 23 has good filtering performance, which can prevent the loss of fine particles while allowing water to pass through, maintaining the stability of the soil; the soil layer 24 is arranged between the geotextile 23 and the mesh box 21, providing an additional support layer for the soil, preventing the gabion structure 2 from directly contacting the geotextile 23.

[0094] It should be understood that after laying the gabion structure 2, the gap between the gabion structure 2 and the upper inclined surface 1a is filled with soil, and a vertical surface is formed between the inclined surface 1a and the plane 1b.

[0095] like Figure 6 , 8 As shown in Figure 9, in one of the embodiments, a plurality of transverse water inlet channels 321b, a plurality of connecting channels 321c and a longitudinal water inlet channel 321d are formed between the two protective membranes 321, and the plurality of transverse water inlet channels 321b are distributed at intervals, and the transverse water inlet channels 321b are connected to the adjacent water storage chamber 321a via the connecting channels 321c, and the longitudinal water inlet channel 321d is connected to the plurality of transverse water inlet channels 321b.

[0096] By arranging multiple transverse water inlet channels 321b, multiple connecting channels 321c and longitudinal water inlet channels 321d between the two protective membranes 321, when it is necessary to fill the water storage chamber 321a with water, the water injection pipe is connected to the longitudinal water inlet channel 321d, and the water enters the multiple transverse water inlet channels 321b through the longitudinal water inlet channel 321d, and enters the multiple connecting channels 321c through the transverse water inlet channels 321b, and enters the multiple water storage chambers 321a through the multiple connecting channels 321c. In the case of one joint, multiple water storage chambers 321a can be filled with water.

[0097] like Figures 11 to 13 As shown, in one embodiment, the protective component 32 also includes a water inlet component 322, and the water inlet component 322 includes a water inlet pipe 3221, a first joint 3222 and a second joint 3223. One end of the water inlet pipe 3221 is connected to the longitudinal water inlet channel 321d, the first joint 3222 is connected to the other end of the water inlet pipe 3221, and the second joint 3223 is inserted into the first joint 3222 and is detachably connected to the first joint 3222. The second joint 3223 is used to connect a water supply pipeline.

[0098] When it is necessary to connect the water supply pipe to the longitudinal water inlet channel 321d, connect the second joint 3223 to the first joint 3222, and make the second joint 3223 and the first joint 3222 snap into place. At this time, water in the water supply pipe can enter the first joint 3222 through the second joint 3223, and enter the water inlet pipe 3221 through the first joint 3222, and then enter the longitudinal water inlet channel 321d through the water inlet pipe 3221, thereby realizing the connection between the water supply pipe and the longitudinal water inlet channel 321d. When the water supply is completed, the second joint 3223 can be removed from the first joint 3222.

[0099] When water is injected into the water storage chamber 321a, if the pressure in the water storage chamber 321a is too high, the drip hole of the protective film 321 may be broken. Fig.12 and Fig.13As shown in one embodiment, the peripheral wall of the first joint 3222 is provided with two fixing grooves, and the fixing grooves are connected to the interior of the first joint 3222; the water inlet member 322 also includes an elastic retaining strip 3224, an elastic connecting strip 3225 and a buckle 3226, the elastic retaining strip 3224 is arranged in the fixing groove, and one end away from the water inlet pipe 3221 is connected to the second joint 3223, the elastic retaining strip 3224 is provided with a clamping groove 3222a on one side away from the interior of the first joint 3222, and one end of the elastic connecting strip 3225 is connected to the second connecting pipe 3221. Head 3223, the buckle 3226 is connected to the elastic connecting strip 3225 and can be clamped in the slot 3222a; when the water pressure in the first joint 3222 is less than the preset value, the buckle 3226 is clamped in the slot 3222a, so as to limit the plugging direction of the second joint 3223 relative to the first joint 3222 through the buckle 3226 and the slot 3222a; when the water pressure in the first joint 3222 is greater than the preset value, the water pushes the elastic baffle 3224 to rotate, and drives the buckle 3226 to disengage from the slot 3222a, thereby releasing the above-mentioned limitation.

[0100] Through the above arrangement, when the second joint 3223 is connected to the first joint 3222, the second clamp is inserted into the first joint 3222. During the insertion process, the buckle 3226 abuts against the outer wall of the first joint 3222 and pushes the elastic connecting strip 3225 to move in a direction away from the axis of the second joint 3223, so that the elastic connecting strip 3225 has an elastic force to push the buckle 3226 to return to its original position. When the buckle 3226 slides to the slot 3222a, it slides into the slot 3222a under the push of the elastic connecting strip 3225, and the buckle 3226 is clamped in the slot 3222a, thereby realizing the connection between the second joint 3223 and the first joint 3222. When the water in the water storage chamber 321a reaches a preset value, the water pressure in the water storage chamber 321a and the longitudinal water inlet channel 321d increases, resulting in an increase in the water pressure in the first joint 3222. The increased water pressure will push the elastic baffle 3224 to rotate outward from the first joint 3222. After the elastic baffle 3224 rotates outward at a certain angle, the buckle 3226 will slide out of the slot 3222a. At this time, the second joint 3223 is separated from the first joint 3222 under the action of the water pressure, which can limit the water pressure of the water supply. When the water supply pressure reaches the set value, the second joint 3223 and the first joint 3222 are automatically disconnected to prevent excessive water pressure from damaging the protective film 321.

[0101] It should be understood that when the elastic retaining strip 3224 is in the initial position, the elastic retaining strip 3224 is sealed against the inner wall of the fixing groove.

[0102] It should be understood that the elastic retaining strip 3224 and the elastic connecting strip 3225 may be made of elastic plastic, spring steel, etc.

[0103] It should be understood that the portion of the second joint 3223 inserted into the first joint 3222 is sealed by fitting with the inner wall of the first joint 3222, and a sealing ring may also be provided for sealing.

[0104] like Fig.13 As shown, in one of the embodiments, the inner diameter of at least part of the first joint 3222 gradually increases along the direction approaching the water inlet pipe 3221, and the water inlet member 322 also includes a sealing sheet 3227 and an elastic portion 3228. The sealing sheet 3227 is slidably built into the portion of the first joint 3222 where the inner diameter gradually increases. The elastic portion 3228 connects the sealing sheet 3227 and the first joint 3222 to provide elastic force for the sealing sheet 3227 to close the first joint 3222; when the second joint 3223 is inserted into the first joint 3222, the second joint 3223 can push the sealing sheet 3227 to slide, so that a gap is formed between the sealing sheet 3227 and the inner wall of the first joint 3222 for water to flow through.

[0105] When the second joint 3223 is inserted into the first joint 3222, the second joint 3223 pushes the sealing sheet 3227 to move, so that a gap for water to flow through is formed between the sealing sheet 3227 and the inner wall of the first joint 3222. The sealing sheet 3227 squeezes the elastic part 3228 during the process of being pushed. When the second joint 3223 is separated from the first joint 3222, the sealing sheet 3227 blocks the first joint 3222 under the push of the elastic part 3228, and can automatically seal the opening of the first joint 3222 at the same time of separation, so as to prevent water in the water storage chamber 321a, the horizontal water inlet channel 321b, the connecting channel 321c and the longitudinal water inlet channel 321d from flowing out through the first joint 3222.

[0109] When the sealing sheet 3227 is facing the direction close to the water inlet pipe 3221, the flexible rope 3229 is in the expanded state and will not pull the elastic baffle to move. When the second joint 3223 is separated from the first joint 3222, the sealing sheet 3227 is reset under the push of the elastic part 3228, and the elastic baffle in the opened state is quickly reset through the flexible rope 3229, so as to prevent the elastic baffle from being in the open state and prevent water from overflowing through the opened elastic baffle.
