Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slope protection, in particular to a roadbed slope protection device. Background Art
[0002] Subgrade slopes refer to the slopes where the two sides of a subgrade cross section meet the ground. They can be categorized as embankment slopes or cutting slopes, and are a key factor affecting subgrade stability. Slopes are often constructed in single-slope, broken-line, and stepped shapes. Within the subgrade structure, the shape and gradient of the slopes significantly impact subgrade stability and project costs.
[0003] After searching, CN 220908435 U, a roadbed slope protection device for highway construction, is found. By hammering the protection frame, the protection frame drives the mounting plate to be clamped into the positioning groove. At the same time, one end of the mounting plate is inserted into the slot. The first spring drives the locking block to reset through elastic force and locks the mounting plate. In this way, the protection frame can be quickly assembled, thereby achieving the purpose of improving construction efficiency.
[0004] However, there are still certain defects in the above application: the above application only emphasizes the role of reinforcing the slope, but lacks a buffering and deceleration mechanism for falling rocks or mud and rock flows. When falling rocks or mud and rock flows slide down from the top of the slope, as the sliding speed increases, the kinetic energy of the falling rocks or mud and rock flows becomes greater and greater. When they hit the protective net below the slope, they will cause a huge impact on the protective net and even cause damage to the protective net. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content
[0005] The purpose of the utility model is to provide a roadbed slope protection device to solve the problems raised in the above background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A roadbed slope protection device includes multiple protection frames, each of which is an octagonal structure. Multiple splicing ears are distributed in an array on the side of the protection frame. The protection frame is also provided with a buffer and deceleration unit. The buffer and deceleration unit includes a frame installed on the protection frame and a metal mesh installed on the frame. The frame is set at an angle.
[0008] As a further solution of the present invention: a plurality of reinforcing rods are further provided on one side of the protection frame.
[0009] As a further solution of the present invention: the frame is rotatably arranged on the protective frame through a pin shaft, the reinforcing rod is a telescopic structure, the reinforcing rod includes a movable sleeve, a telescopic rod movably inserted at one end of the movable sleeve, and a spring installed in the movable sleeve, the movable sleeve is hingedly installed on the protective frame, and the telescopic rod is hingedly installed on the side of the frame.
[0010] As a further solution of the present invention: the device also includes a splicing assembly, which includes a splicing plate, a plurality of plug rods installed on the bottom surface of the splicing plate, and a conical rod threadedly installed on the splicing plate. The splicing plate is movably embedded in a groove formed by splicing four protective frames, and the connecting ear is provided with a socket for plugging with the plug rod.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] By installing a frame and a metal mesh on the protective frame, the utility model can not only protect the slope but also decelerate the rockfall and mud-rock flow when rockfall or debris flow slides down from above the slope, thereby reducing the kinetic energy of the rockfall or mud-rock flow. In combination with the protective mesh arranged below the slope, the safety hazards caused by rockfall or mud-rock flow are greatly reduced, and the utility model has the advantage of better protection effect.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0019] Example 1
[0020] See also Figure 1-4, a roadbed slope protection device, the device includes multiple protection frames 1, the protection frame 1 is an octagonal structure, the side array of the protection frame 1 is distributed with multiple splicing ears 2, the protection frame 1 is also provided with a buffer deceleration unit, the buffer deceleration unit includes a frame 3 installed on the protection frame 1 and a metal mesh 4 installed on the frame 3, the frame 3 is arranged obliquely, by installing the frame 3 and the metal mesh 4 on the protection frame 1, when falling rocks or debris flows slide from above the slope, the multiple protection frames 1 can not only protect the slope, but also have a deceleration effect on falling rocks and debris flows, reducing the kinetic energy of falling rocks or debris flows, and cooperating with the protection net arranged below the slope, greatly reducing the safety hazards caused by falling rocks or debris flows, and having the advantage of better protection effect.
[0021] Among them, a plurality of reinforcing rods 5 are further provided on one side of the frame 3 on the protection frame 1. The provision of the reinforcing rods 5 improves the strength of the frame 3 and prevents the frame 3 from being deformed or bent due to impact.
[0022] Preferably, the frame 3 is rotatably set on the protective frame 1 through a pin shaft 6, and the reinforcing rod 5 is a telescopic structure. The reinforcing rod 5 includes a movable sleeve 7, a telescopic rod 8 movably inserted at one end of the movable sleeve 7, and a spring installed in the movable sleeve 7 (not shown in the figure). The movable sleeve 7 is hingedly mounted on the protective frame 1, and the telescopic rod 8 is hingedly mounted on the side of the frame 3. Through such an arrangement, when falling rocks or mud and rock flows slide down the slope and hit the frame 3, the telescopic structure of the reinforcing rod 5 is set, so that the frame 3 can be flipped to a certain extent under the action of the impact force, thereby avoiding the deformation of the frame 3 caused by rigid collision, and further improving the strength of the frame 3.
[0023] Example 2
[0024] This embodiment is improved on the basis of embodiment 1, specifically:
[0025] See also Figure 2-4 The device also includes a splicing assembly, which includes a splicing plate 9, a plurality of plug rods 10 installed on the bottom surface of the splicing plate 9, and a tapered rod 11 threadedly installed on the splicing plate 9. The splicing plate 9 is movably embedded in a groove formed by splicing four protective frames 1, and a socket for plugging with the plug rod 10 is provided on the connecting ear. The setting of the splicing assembly can quickly fix the spliced protective frame 1, which improves the installation efficiency of the protective frame 1 compared with the prior art that requires fixing the protective frame 1 one by one.
[0026] Specifically, when installing the protective frame 1, first use four protective frames 1 as a group. After splicing the four protective frames 1 in this way, install the splicing plate 9 in the groove formed by the splicing of the four protective frames 1, and make the four plug rods 10 on the bottom surface of the splicing plate 9 respectively inserted into the jacks of the four connecting ears. Then, rotate the tapered rod 11 on the splicing plate 9. After the tapered rod 11 is drilled into the slope, the four protective frames 1 can be fixed. And so on, with the four protective frames 1 as the center of the circle, gradually assemble the remaining protective frames 1 outward;
[0027] After installation, when falling rocks or debris flows slide down from above the slope, multiple protective frames 1 can not only protect the slope, but also slow down the falling rocks and debris flows, reducing the kinetic energy of the falling rocks or debris flows. Combined with the protective net set below the slope, the safety hazards caused by falling rocks or debris flows are greatly reduced, and the protective effect is better.
