Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a prefabricated revetment slope structure for water conservancy projects. Background Technology

[0002] In water conservancy projects, the revetment structure of riverbanks plays a crucial role in preventing water erosion, protecting the stability of the riverbanks, and ensuring the safety of personnel. Currently, the common method for constructing revetment slopes is by on-site cast-in-place concrete, which involves directly erecting formwork and pouring cement at the slope, allowing it to solidify and form a monolithic revetment. However, this traditional concrete revetment method has certain drawbacks.

[0003] First, the surface of concrete revetments is relatively smooth, and after long-term erosion by water flow, the surface becomes even smoother, resulting in reduced friction. When people walk or work on the bank slope, they are prone to slipping and falling into the water, posing a significant safety hazard, especially in water conservancy facilities such as reservoirs, rivers, and canals.

[0004] Secondly, traditional cement revetments are prone to cracking due to long-term exposure to water erosion and climate change. When water enters these cracks, it accelerates the damage to the revetment layer, causing it to peel off or even collapse. This not only reduces the service life of the revetment structure but also leads to slope instability, affecting the overall safety of the water conservancy project. Furthermore, the formation of cracks weakens the revetment layer's ability to block water, potentially leading to seepage and exacerbating soil erosion. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated revetment slope structure for water conservancy projects, which can improve the anti-slip performance of the revetment surface and enhance the crack resistance and durability of the structure.

[0006] This utility model is achieved through the following technical solution:

[0007] A precast revetment slope structure for hydraulic engineering, comprising:

[0008] A cement base layer, which is used to be poured on a bank slope that has been leveled and compacted.

[0009] An asphalt layer is laid on the surface of the cement base layer;

[0010] The protective layer comprises multiple protective blocks spliced ​​together. The outer side of each protective block is provided with a long strip-shaped baffle. The outer side of the baffle is in the shape of an upward-curving arch, and the inner side of the baffle has an inward-retracting water guide groove.

[0011] A fastener is used to fix the guard block to the cement base.

[0012] Furthermore, a plug and a slot are respectively provided between two adjacent guard blocks installed horizontally. The slot is L-shaped, with the open end of the slot located outside the guard block. The plug is used to be inserted from the open end of the slot and enter the bottom of the slot.

[0013] Furthermore, a casting groove is provided on the side of the guard block near the insert block. The casting groove has a T-shaped cross-section and is used to communicate with the slot of the adjacent guard block.

[0014] Furthermore, the fixing component includes a steel bar and a hook rod. Multiple steel bars are provided, and the steel bars are evenly embedded in the cement base along the slope of the bank. Multiple elongated grooves are opened on the cement base, and the steel bars are exposed in the elongated grooves. The elongated grooves are used for the hook rod to move in. The hook rod is fixedly installed on the back of the retaining block and is used to hook onto the steel bar.

[0015] Furthermore, a limiting piece is fixedly provided along the length direction of the hook portion of the hook rod. The limiting piece is an elastic piece, and multiple barbs are provided along the length direction of the limiting piece. The limiting piece is inclined from the side where the reinforcing bar moves into the hook portion of the hook rod.

[0016] Furthermore, the limiting plates are fixedly disposed on both sides of the hook portion of the hook rod, and the limiting plates on both sides are arranged obliquely to both sides.

[0017] Furthermore, the hook end of the hook rod is provided with a guide bevel.

[0018] Furthermore, a rib is fixedly provided on the guard block, and a connecting port is provided on the rib, which is connected to the water guide channel.

[0019] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0020] 1. This utility model improves the overall waterproof performance by laying an asphalt layer on the surface of a cement base layer, reducing water penetration and erosion of the cement base layer, thereby effectively reducing the risk of cracking and enhancing the bonding stability between the cement base layer and the retaining layer. The retaining layer is composed of multiple retaining blocks spliced ​​together. Each retaining block has an upward-curving arched baffle on its outer side, which not only effectively blocks water erosion and reduces direct impact on the revetment structure, but also provides a certain degree of anti-slip effect, reducing the risk of people slipping. At the same time, the inner side of the baffle has an inward-curving water-guiding groove, which can rationally guide water flow out, reduce water retention on the revetment surface, and further reduce the impact of water erosion on the structure. The retaining blocks are firmly installed on the cement base layer with fasteners, making the overall structure more solid and reliable, thereby significantly improving the crack resistance and durability of the revetment slope, extending its service life, and improving the safety and stability of the water conservancy project.

[0021] 2. This utility model utilizes a steel bar hook connection with the hook rod on the back of the retaining block. This not only enhances the fixing effect of the retaining block, ensuring its stability under water erosion or external forces, but also simplifies the installation process and improves construction efficiency. This connection method avoids the structural stress concentration problems that may result from traditional bonding or rigid fixing, giving the retaining block a certain degree of adaptability to temperature changes or slight displacement, thereby reducing the risk of cracking due to stress accumulation. Furthermore, this structure facilitates later maintenance and replacement, improving the overall durability and engineering adaptability of the revetment slope. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example

[0031] The following is for reference Figures 1-5 As shown in the figure, and further illustrated by a specific embodiment, this embodiment provides a prefabricated revetment slope structure for water conservancy projects. The structure includes a cement base layer 1, an asphalt layer 11, a retaining layer 2, and fasteners 3. The components work together to improve the protection effect of the slope.

[0032] The cement base course 1 is poured onto the leveled and compacted slope surface to provide a solid foundation. To improve the crack resistance of the cement base course 1, steel mesh or reinforcing fiber materials can be laid inside it to maintain its structural integrity under external impact or temperature changes. In addition, the surface of the cement base course 1 is roughened to improve the adhesion of the asphalt layer 11.

[0033] The asphalt layer 11 is laid on the surface of the cement base layer 1. Its main function is to improve the waterproof performance of the overall structure, reduce water penetration, and prevent the cement base layer 1 from cracking due to long-term dampness. At the same time, the asphalt layer 11 has a certain degree of flexibility, which can buffer the impact of water flow and reduce stress concentration inside the structure.

[0034] The retaining layer 2 is composed of multiple interconnected retaining blocks 21, each prefabricated with cement to ensure precise dimensions and convenient construction. A long, narrow strip 211 is integrally formed on the outer side of each retaining block 21, located at the top of the block and forming an upward-curving arch, similar to the shape of an arched mountain. This structure not only effectively blocks water erosion and reduces the erosion of the bank slope, but also prevents pedestrians or workers from slipping in wet conditions, improving safety. The inner side of the strip 211 features a recessed water channel 212, which guides water flow orderly along the surface of the retaining block 21, preventing water from stagnating on the surface of the retaining structure and thus reducing the risk of erosion to the retaining layer 2 and the cement base layer 1.

[0035] The fastener 3 is mainly used to firmly fix the retaining block 21 to the cement base layer 1, improving the overall structural stability. Preferably, the steel bar 31 is hooked to the hook rod 32 on the back of the retaining block 21, making the installation of the retaining block 21 more convenient and ensuring that it remains firmly connected even when subjected to water flow impact or external forces. Compared to traditional bonding or rigid fixing methods, this connection method allows the retaining block 21 to have a certain degree of self-adaptability to temperature changes or slight displacement, avoiding cracks caused by stress concentration and improving the crack resistance and durability of the structure. Furthermore, this fixing method facilitates later maintenance and replacement, extending the service life of the revetment slope. Of course, in other implementations, the fastener 3 can also be made of expansion bolts.

[0036] Reference Figure 1 and Figure 2 As shown, the guardrail block 21 splicing structure adopts a horizontal installation method, with an insert 22 and a slot 23 respectively provided between two adjacent guardrail blocks 21. The slot 23 can be square or round, and has an L-shaped structure, with its open end located on the outside of the guardrail block 21. During installation, the insert 22 is inserted through the open end of the slot 23 and slides to the bottom of the slot 23, forming a tight fit between adjacent guardrail blocks 21, thus achieving a stable splicing. This design can prevent the guardrail blocks 21 from shifting or loosening under long-term water erosion or external force, while also facilitating installation and disassembly, improving construction efficiency.

[0037] To further enhance the connection strength between the guard blocks 21, a casting groove 24 with a T-shaped cross-section is provided on the side of the guard block 21 near the insert block 22. This casting groove 24 is designed to connect with the slot 23 of the adjacent guard block 21. When cement mortar is poured into the slot 23 and the casting groove 24, the cement mortar forms an integrated connection after solidification, thereby significantly improving the bonding strength between the adjacent guard blocks 21.

[0038] Reference Figure 3 and Figure 4 As shown, this embodiment further optimizes the fixing structure of the retaining block 21. Specifically, through the connection between the reinforcing bar 31 and the hook rod 32, the retaining block 21 can be stably fixed to the cement base layer 1, while improving the overall structure's erosion resistance and durability. The fixing component 3 includes the reinforcing bar 31 and the hook rod 32. Multiple reinforcing bars 31 are provided, evenly embedded in the cement base layer 1 along the slope of the bank to provide a reliable fixing foundation. Multiple elongated grooves 12 are formed on the surface of the cement base layer 1 to accommodate the reinforcing bars 31, leaving some exposed within the grooves for connection with the hook rod 32.

[0039] The hook rod 32 is integrally formed on the back of the guard block 21. During installation, the hook rod 32 is connected to the reinforcing bar 31 by hooking, thereby achieving a stable fixation between the guard block 21 and the cement base 1. When installing the guard block 21, the hook rod 32 can be moved in along the direction of the elongated groove 12 to hook onto the reinforcing bar 31, enhancing the overall stability of the guard block 21 and reducing loosening or detachment caused by water erosion or external forces.

[0040] Reference Figure 4 and Figure 5 As shown, to further improve the connection stability between the hook rod 32 and the rebar rod 31 and prevent loosening due to vibration or external force, a limiting piece 4 is fixedly installed along the length of the hook portion 321 of the hook rod 32. The limiting piece 4 is an elastic piece that provides a certain buffer when subjected to external impact, preventing damage to the connecting parts, and facilitating insertion into the rebar rod 31. Multiple barbs 41 are provided along the length of the limiting piece 4. The design of the barbs 41 enhances friction and prevents the hook rod 32 from shifting or slipping off the rebar rod 31. The limiting piece 4 is inclined on one side of the hook portion 321 from the rebar rod 31, facilitating quick hooking of the hook rod 32 onto the rebar rod 31 and insertion of the rebar rod 31 into the hook rod 32. The limiting pieces 4 are fixedly installed on both sides of the hook portion 321 of the hook rod 32, with the limiting pieces 4 extending obliquely outwards, thus forming multi-directional limiting during connection and further improving the fixing effect.

[0041] Reference Figure 3 As shown, the retaining block 21 is integrally formed with ribs 25 to enhance the overall strength of the retaining block 21 and prevent structural deformation caused by external forces. The ribs 25 have connecting openings 251 that are connected to the water guide channel 212, allowing water to flow normally within the channel, thereby improving drainage efficiency, reducing the scouring force of the water flow on the retaining block 21, and further enhancing the scouring resistance and durability of the revetment slope.

[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
