Description

Technical Field

[0001] This invention belongs to the field of water conservancy seepage prevention and reinforcement technology, specifically a flexible composite material water conservancy slope seepage prevention and reinforcement device. Background Technology

[0002] As a key infrastructure for ensuring social and economic development, water conservancy projects require slope seepage prevention and reinforcement as a core link in maintaining the safety and stability of the project. This directly relates to the realization of core functions such as flood control, water supply, and power generation, as well as the safety of life and property in the surrounding area. Although rigid supports such as masonry and concrete have high strength, they have poor flexibility and are difficult to adapt to the deformation of rock and soil, as well as complex geological conditions such as abundant groundwater and soft soil. They are prone to cracking and leakage, and have long construction cycles and high costs. Although flexible supports such as traditional geosynthetics have a certain degree of deformation adaptability, their seepage prevention performance is not durable enough. They are prone to aging after long-term water erosion, and their reinforcement strength is also difficult to meet the requirements of high-level seepage prevention and reinforcement. At the same time, they have problems such as complicated construction procedures and low efficiency in adapting to complex slopes.

[0003] CN116479921A discloses a drainage structure and construction method for expansive soil embankments. The drainage structure includes a stepped slope, a first drainage device, a second drainage device, an ecological protection device, and a section energy controller. The first drainage device includes hollow anchors, a pumping head, and a vacuum head. The second drainage device includes a lime-soil layer, a vacuum drainage pipe, an expansive soil waterproofing pad, and a blind drain. The ecological protection device is installed on the second drainage device and includes a sand cushion layer, several bags of soil, a topsoil layer, and plants. The section energy controller is used to monitor water accumulation, vacuum degree, settlement, and soil moisture. The drainage structure combines vacuum drainage, seepage prevention and moisture retention, load expansion reduction, and ecological protection. The construction method of this invention is simple and easy to implement, completing the treatment and improvement of expansive soil embankment slopes in one stop, reducing construction costs, and shortening the construction period from filling, consolidation, reinforcement to greening.

[0004] The device is simple and easy to use, and it can treat and improve the slope of expansive soil embankment in one stop. However, the device cannot be used to reinforce the slope surface with large-area seepage prevention. Therefore, a flexible composite material seepage prevention and reinforcement device for water conservancy slope is proposed. By using two sets of seepage prevention materials and containing seepage prevention interlayer, a three-layer seepage prevention and reinforcement surface is formed to improve the strength of water conservancy slope. Summary of the Invention

The weight of the counterweight column is greater than the weight of the high-strength plastic geotextile and the cement blanket. The weight of the counterweight column itself is greater than that of the high-strength plastic geotextile and the cement blanket. It can press the two tightly against the slope surface of the hydraulic slope by gravity to prevent the seepage prevention material from shifting due to water flow impact or wind. The bottom spike-shaped limiting column is inserted into the slope to further enhance the fixing effect, prevent the seepage prevention material from sliding along the slope surface, and ensure the integrity of the seepage prevention layer coverage.

[0008] Preferably, the positioning blocks and limiting posts are provided in several groups, the positioning blocks and limiting posts are arranged at equal intervals, the bottom end of the limiting posts is provided with spikes, and the limiting posts are inserted into the hydraulic slope.

Multiple groups of equally spaced grouting cylinders can evenly deliver modified concrete to different areas of the slope. The overall reinforcement frame formed by the force-equalizing rod can evenly distribute the slope pressure, enhance the overall anti-slip stability of the slope, and prevent excessive local stress from causing reinforcement failure.

The bank-side fixing blocks are fixed to the top of the hydraulic slope to provide stable support, the high-strength plastic geotextile is laid to cover the slope surface, and the counterweight columns are inserted into the slope by their own weight and spiked limiting columns to fix the connection node between the geotextile and the cement blanket. After the two are folded, they form a pouring area, which, together with subsequent grouting, forms a composite seepage-proof structure, ultimately achieving the effect of quickly constructing a large-area slope seepage-proof foundation and improving seepage-proof stability.

[0017] This invention, through the coordinated arrangement of grouting cylinders, grouting boxes, and reinforcing screws, enables the device to strengthen the bond between the internal reinforcement and the seepage prevention layer of the slope, thereby improving the overall bearing capacity.

The grouting rods are inserted into the grouting cylinders, and the modified concrete is transported to the pouring area and pouring trench through the grouting grooves and limiting grouting grooves. This not only fixes the anti-seepage material but also connects adjacent pressure blocks, ultimately simplifying the construction process and forming a roadside edge that is both protective and aesthetically pleasing.

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1 to 10 As shown, the present invention provides a flexible composite material hydraulic slope seepage prevention and reinforcement device, including a hydraulic slope 1, a seepage prevention mechanism 2 installed at the top of the hydraulic slope 1, a reinforcement mechanism 3 provided inside the hydraulic slope 1, and a grouting fixing mechanism 4 installed at the top of the seepage prevention mechanism 2.

[0026] like Figures 1 to 7As shown, the seepage prevention mechanism 2 includes a bank fixing block 201, a high-strength plastic geotextile 202, and a counterweight column 203. The bank fixing block 201 is fixed to the top of the hydraulic slope 1. The high-strength plastic geotextile 202 is fixed to the outside of the bank fixing block 201. A counterweight column 203 is fixed to one end of the high-strength plastic geotextile 202. A cement blanket 206 is fixed to one end of the counterweight column 203. A positioning block 204 is fixed to the top of the counterweight column 203. A limit column 205 is fixed to the bottom of the counterweight column 203. The high-strength plastic geotextile 202... The surface is provided with positioning holes. The weight of the counterweight column 203 is greater than the weight of the high-strength plastic geotextile 202 and the cement blanket 206. Several sets of positioning blocks 204 and limiting columns 205 are provided. The positioning blocks 204 and the limiting columns 205 are arranged at equal intervals. The bottom end of the limiting column 205 is provided with spikes. The limiting column 205 is inserted into the hydraulic slope 1. The folded interlayer of the high-strength plastic geotextile 202 and the cement blanket 206 is the pouring area. The weight of the bank fixing block 201 is greater than the weight of the high-strength plastic geotextile 202 and the cement blanket 206.

[0027] The above scheme is adopted as follows: by fixing the bank fixing block 201 to the top of the hydraulic slope 1, and laying the high-strength plastic geotextile 202 on the surface of the hydraulic slope 1, the counterweight column 203 fixes the connection node of the high-strength plastic geotextile 202 and the cement blanket 206 to the bottom edge of the hydraulic slope 1 by its own weight and the limiting column 205. After the counterweight column 203 is fixed, the cement blanket 206 is unfolded. After the reinforcement screw 303 and the uniform force bar 304 are installed, the cement blanket 206 and the high-strength plastic geotextile 202 are folded again, so that the cement blanket 206 covers the high-strength plastic geotextile 202 and the end contacts the bank fixing block 201. The pressure block 401 is used to press and fix it, so that the middle of the high-strength plastic geotextile 202 and the cement blanket 206 form a pouring area after folding.

[0028] like Figures 1 to 7 As shown, the reinforcement mechanism 3 includes a grouting cylinder 301, a grouting box 302, and a reinforcing screw 303. The grouting cylinder 301 is inserted inside the high-strength plastic geotextile 202. The grouting box 302 is fixed to the outside of the grouting cylinder 301. The reinforcing screw 303 is threadedly connected to the inside of the grouting box 302. A uniform force rod 304 is sleeved on the outside of the reinforcing screw 303. Several sets of grouting cylinders 301 are provided. The length of the grouting cylinder 301 from top to bottom is... The grouting cylinders 301 are arranged at equal intervals in a decreasing manner. The output end of the grouting cylinder 301 is connected to the input end of the grouting box 302. The surface of the grouting box 302 is provided with through holes. Several sets of uniform force rods 304 are provided. The uniform force rods 304 are arranged in an array about the central axis of the reinforcing screw 303. The grouting cylinder 301 is inserted into the hydraulic slope 1. The top of the grouting cylinder 301 is provided with an insertion hole. The reinforcing screw 303 and the positioning block 204 are threaded together.

[0029] The above scheme is adopted as follows: after the reinforcing screw 303 is screwed into multiple sets of grouting boxes 302, the end is threaded to the positioning block 204, and the uniform force rod 304 is fixed on two sets of reinforcing screws 303. After the high-strength plastic geotextile 202 and cement blanket 206 are folded, modified concrete is injected into the interior of the grouting rod 402 through the grouting rod 402. The modified concrete uses ordinary concrete as the base material, and high molecular fiber or rubber particles are added to improve flexibility. It is combined with penetrating crystalline waterproofing agent to enhance seepage resistance. After the modified concrete enters the interior of the grouting rod 402, it is injected into the grouting cylinder 301 in the hole punching machine, and then into the interior of the grouting box 302 and the pouring area through the grouting cylinder 301.

[0030] like Figures 1 to 10 As shown, the grouting fixing mechanism 4 includes a pressure block 401, a grouting rod 402, and a grouting groove 403. The pressure block 401 is abutted against the top of the bank fixing block 201 and the cement blanket 206. Several sets of pressure blocks 401 are provided. One end of the pressure block 401 is provided with a limiting groove, and the other end of the pressure block 401 is fixed with a limiting block. The outer wall of the limiting block is attached to the inner wall of the limiting groove. The bottom end of the pressure block 401 is fixed with a grouting rod 402. The outer wall of the grouting rod 402 is attached to the inner wall of the grouting cylinder 301. The grouting rod 402 and the grouting cylinder 301 are inserted into... The output end of the grouting rod 402 is connected to the grouting cylinder 301. The top of the pressure block 401 is provided with a grouting groove 403. One end of the grouting groove 403 is provided with a limiting grouting groove 404. The bottom end of the pressure block 401 is fixed with a positioning edge 405. The top of the pressure block 401 is provided with a positioning groove 406. The inside of the pressure block 401 is provided with a casting groove 407. The outer diameter of the positioning edge 405 is equal to the outer diameter of the positioning groove 406. The input end of the positioning edge 405 is connected to the limiting grouting groove 404. The positioning edge 405 and the positioning groove 406 are inserted together.

[0031] The above scheme is adopted: after aligning the grouting rod 402 with multiple sets of grouting cylinders 301 and inserting it, the pressure block 401 is pressed on the top of the cement blanket 206 and the bank fixing block 201, thereby fixing the whole device. After the grouting area is fixed by grouting through the grouting groove 403 and the grouting rod 402, the pouring continues, so that it enters the positioning edge 405 through the limiting grouting groove 404 and is injected into the pouring groove 407 through the positioning edge 405. The two pressure blocks 401 are connected after the modified concrete has solidified.

[0032] The working principle and usage process of this invention are as follows: First, the bank fixing block 201 is fixed to the top of the hydraulic slope 1, and the high-strength plastic geotextile 202 is laid on the surface of the hydraulic slope 1. The counterweight column 203, through its own weight and the limiting column 205, fixes the connection node between the high-strength plastic geotextile 202 and the cement blanket 206 to the bottom edge of the hydraulic slope 1. After fixing the counterweight column 203, the cement blanket 206 is unfolded. The reinforcing screw 303 is threaded into multiple sets of grouting boxes 302, and its end is threaded to the positioning block 204. The uniform force rod 304 is fixed to two sets of reinforcing screws 303. After fixing the high-strength plastic geotextile 202 and the cement blanket 206, the connection node between the high-strength plastic geotextile 202 and the cement blanket 206 is fixed to the bottom edge of the hydraulic slope 1. After the mud blanket 206 is folded, modified concrete is injected into the grouting rod 402 through the grouting rod 402. The modified concrete uses ordinary concrete as the base material, and incorporates polymer fibers or rubber particles to improve flexibility. It is combined with a penetrating crystalline waterproofing agent to enhance impermeability. After the modified concrete enters the grouting rod 402, it is injected into the grouting cylinder 301 inside the hole puncher, and then continues to be injected into the grouting box 302 and the pouring area through the grouting cylinder 301, thereby filling the pouring area. After the modified concrete solidifies, it forms a three-layer impermeable layer with the cement blanket 206 and the high-strength plastic geotextile 202. Moreover, the solidified modified concrete layer can improve the resistance strength of the hydraulic slope 1 during hardening due to the properties of the concrete itself.

[0033] Finally, by aligning the grouting rod 402 with multiple sets of grouting cylinders 301 and inserting it, the pressure block 401 is pressed onto the top of the cement blanket 206 and the bank fixing block 201, thereby fixing the entire device. After the grouting area is fixed by grouting through the grouting groove 403 and the grouting rod 402, grouting continues, allowing the grouting to enter the positioning edge 405 through the limiting grouting groove 404 and be injected into the grouting groove 407 through the positioning edge 405. This connects the two pressure blocks 401 after the modified concrete has solidified. The installed pressure block 401 can naturally form a curb at the top of the hydraulic slope 1, improving the aesthetics of the road.

[0034] During the solidification process of modified concrete, the internal polymer fibers can disperse stress and the deformation adaptability can be improved through rubber particles. It can produce flexible deformation with the slight settlement or temperature change of the hydraulic slope 1, avoiding rigid cracking that would lead to seepage failure and further strengthening the sealing of the seepage layer. The modified concrete filled in the pouring area is closely bonded with the high-strength plastic geotextile 202 and cement blanket 206 to form a three-layer composite structure of "geotextile-concrete-cement blanket". The three-layer structure works together to adapt to the slope deformation through the flexibility of the geotextile and cement blanket, and improve the overall bearing strength with the help of the concrete layer, so as to realize the integration of seepage prevention and reinforcement functions.

[0035] The modified concrete injected by multiple grouting cylinders 301 penetrates into the pores inside the hydraulic slope 1, combines with the slope soil to form reinforced soil, and enhances the slope's own shear strength. The through holes on the surface of the grouting box 302 allow the concrete to spread evenly to the surrounding soil, avoiding structural unevenness caused by excessive local grouting concentration. After the concrete solidifies, the equipotential rod 304 continuously maintains the force balance of multiple sets of reinforcing screws 303, preventing the screws from loosening due to local stress changes in the slope, and ensuring the long-term stability of the reinforcement frame. After the pressure block 401 is connected, its top positioning groove 406 is precisely inserted into the positioning edge 405 of the adjacent pressure block 401 to form a continuous top protection structure.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
