Description

Technical Field

[0001] The utility model relates to the technical field of slope support, in particular to a prefabricated component for a river slope. Background Art

[0002] Prefabricated riverbank components are key components for riverbank stabilization and protection in water conservancy projects. These components are typically prefabricated in factories and then transported to site for installation. Prefabricated components can effectively reinforce riverbank structures and reduce soil erosion. The standardized and modular nature of prefabricated components allows for rapid assembly, improving construction efficiency.

[0003] In the existing technology, multiple prefabricated components are usually arranged closely together, buried in the ground of the river slope or placed directly on the surface of the river slope, covered with soil and rocks, and then covered with protective nets on the outside of the multiple prefabricated components to ensure the stability of the placement of the prefabricated components, reduce the direct impact of foreign objects on the slope, and resist the influence of water erosion and other natural factors;

[0004] However, when using a protective mesh to restrict the movement of prefabricated components, the protective mesh will be locally damaged during long-term use due to its own strength, and the restraint on the prefabricated components will decrease. After losing effective restraint, the prefabricated components may tilt or even partially move out of their original position due to factors such as gravity and water flow impact, causing gaps or breaks in the originally continuously covered protective layer, weakening the overall protection of the slope and increasing the risk of soil erosion. Therefore, the present application provides a prefabricated component for river slopes. Utility Model Content

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Provided is a river channel slope prefabricated component, comprising a hollow component body, wherein the circumferential sides of the hollow component body are respectively provided with docking holes, a docking rod is inserted and installed in the hollow component body, and an elastic tightening sleeve is fixedly installed at the end of the docking rod, the docking rod passes through the docking hole on the hollow component body from the inside to the outside and is plug-connected with the docking hole of the adjacent hollow component body, and the outer side surface of the elastic tightening sleeve can be tightened against the inner side surface of the docking hole of the adjacent hollow component body.

[0008] For the elastic tightening sleeve used in this application, an alternative technical solution is that the outer diameter of the elastic tightening sleeve is greater than the outer diameter of the docking rod.

[0009] For the elastic tightening sleeve used in this application, another alternative technical solution is that an annular embedding lip is integrally formed on the outer side of the end of the elastic tightening sleeve.

[0013] Further, a breathable soil retaining plate is detachably and fixedly installed on the top of the inner frame.

[0014] Further, a limit cover is slidably installed on the upper side of the inner frame. A handle and a plurality of insertion posts are respectively provided on the upper and lower sides of the limit cover.

[0017] 2. For the precast component of the river channel slope of the present utility model example, hold the handle and control the limit cover to be pulled out from the inner frame, so that the plurality of insertion posts are separated from the plate spring. During this process, the plate spring changes from a bent state to a straight state. Utilizing the elastic deformation ability of the plate spring itself, drive the elastic tightening sleeve to sequentially penetrate the docking holes in the two hollow member main bodies, replacing the means of knocking the end of the docking rod in the first embodiment, achieving the purpose of saving effort and improving the installation efficiency of the precast component of the river channel slope.

[0031] Embodiment 1:

[0032] As Figure 1 and Figure 2 shown, this embodiment provides a precast component for a riverbank slope, including a hollow component main body 11. Docking holes 12 are respectively arranged on the peripheral side of the hollow component main body 11, and at least two docking rods 22 are inserted and installed in the hollow component main body 11;

[0033] An elastic tightening sleeve 23 is fixedly installed at the end of the docking rod 22. The docking rod 22 penetrates through the docking hole 12 on the hollow component main body 11 from the inside to the outside and is inserted and connected with the docking hole 12 of the adjacent hollow component main body 11. The outer side surface of the elastic tightening sleeve 23 can be tightly abutted against the inner side surface of the docking hole 12 of the adjacent hollow component main body 11.

[0034] In this embodiment, the method of restricting the position of the docking rod 22 inside the docking hole 12 is: a T-shaped limiting disc is arranged at the end of the docking rod 22 away from the elastic tightening sleeve 23.

[0035] In use, a plurality of hollow member bodies 11 are closely arranged together, and then the end of the docking rod 22 is struck, so that the elastic tightening sleeve 23 sequentially penetrates through the docking holes 12 in the two hollow member bodies 11 to position the two; repeat the above operation, extend a plurality of docking rods 22 from the respective corresponding hollow member bodies 11, restrict the relative positions of the plurality of hollow member bodies 11, so that the tops of the plurality of hollow member bodies 11 are kept in the same virtual plane, replacing the use of a protective net cover, and avoiding the phenomenon that components may tilt or even partially deviate from their original positions due to factors such as gravity and water flow impact, resulting in gaps or breaks in the originally continuously covered protective layer, thereby improving the stability of the overall structure after assembly and ensuring the reliability and durability of the slope protection efficiency.

[0036] As Figure 2 and Figure 3 shown, for the way that the elastic tightening sleeve 23 abuts against the inner side surface of the docking hole 12, the outer diameter of the elastic tightening sleeve 23 can be set to be larger than the outer diameter of the docking rod 22; or an annular embedding lip is integrally formed on the outer side of the end of the elastic tightening sleeve 23, and by using the elastic deformable characteristic of the elastic tightening sleeve 23, the elastic tightening sleeve 23 abuts against the inner side surface of the docking hole 12.

[0037] Embodiment Two:

[0038] The features identical to those of Embodiment One in this embodiment will not be described in detail. The different solution of this embodiment from Embodiment One is: As Figure 2 shown, in this embodiment, the docking rod 22 is connected to the hollow member body 11 through a plate spring 21. The plate spring 21 is fixedly installed on the inner side of the hollow member body 11, and the docking rod 22 is fixedly installed in the middle of the plate spring 21.

[0039] A limit cover 31 is slidably installed on the upper side of the inner frame 13. A handle 33 and a plurality of insertion posts 32 are respectively arranged on the upper and lower sides of the limit cover 31. The plurality of insertion posts 32 are grouped in pairs and are simultaneously inserted into one side of the plate spring 21, so that the plate spring 21 maintains a bent state.

[0040] Grip the handle 33 and control the limit cover 31 to be pulled out from the inner frame 13, so that the plurality of insertion posts 32 are separated from the plate spring 21. During this process, the plate spring 21 changes from a bent state to a straight state. By using the elastic deformation ability of the plate spring 21 itself, the elastic tightening sleeve 23 is driven to sequentially penetrate through the docking holes 12 in the two hollow member bodies 11, replacing the means of striking the end of the docking rod 22 in Embodiment One, achieving the purpose of labor saving and improving the installation efficiency of the precast components for the river channel slope.

[0041] In order to reduce the assembly difficulty of the components themselves, as Figure 3As shown, an inner frame 13 is fixedly installed inside the hollow member body 11, and the plate spring 21 is fixedly connected to the hollow member body 11 through the inner frame 13. First, a plurality of plate springs 21 are installed on the inner frame 13, and then the inner frame 13 is installed inside the hollow member body 11, so that it is not necessary to repeatedly fix and install the plate spring 21 and the hollow member body 11, simplifying the operation process and increasing the production efficiency of the equipment.

[0042] Embodiment 3:

[0043] The features identical to those of Embodiment 2 in this embodiment will not be described in detail. The difference between this embodiment and Embodiment 2 lies in that, as Figure 1 and Figure 2 shown, in this embodiment, a breathable soil retaining plate 14 is detachably and fixedly installed at the top of the inner frame 13. The breathable soil retaining plate 14 shields the hollow member body 11. Soil and plant seeds can be loaded into the hollow member body 11. The breathable soil retaining plate 14 plays a role in ventilation and light transmission, so that plants can grow inside the hollow member body 11. By utilizing the close combination between the plant roots and the soil on the river bank slope, the placement stability of the precast members on the river bank slope is increased.
