Description

Technical Field

[0001] The utility model relates to the technical field of slope support devices, in particular to a slope support device for civil engineering. Background Technique

[0002] Slope protection refers to a series of reinforcement measures taken for road surface slopes or slope environments to prevent the erosion of surface water runoff on slopes, ensure the stability and safety of slopes. The main purpose of slope protection is to protect slopes from natural factors such as rain erosion and wind erosion, and at the same time prevent geological disasters such as slope landslides and collapses to ensure the safety of roads, buildings and personnel. In addition, slope protection also helps to beautify the environment, prevent soil erosion and maintain ecological balance.

[0003] The common slope protection means in the prior art is mesh hanging protection. Holes are drilled on the slope surface, then anchor rods are inserted and grouted with cement mortar. After the cement mortar solidifies and the anchor rods are stable, the metal mesh and the anchor rods are fixed. However, after the anchor rods in such slope support devices in the prior art are inserted into the holes, there is no other limiting structure, resulting in limited fixing force between the anchor rods and the holes. Therefore, an improved slope support device for civil engineering is needed to solve this problem. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A slope support device for civil engineering, including a slope, installation holes are provided on the surface of the slope, and a fixing mechanism for fixing a protection net is arranged inside the installation holes. The fixing frame includes an anchor rod body, a cavity, an installation block, a screw rod, an extension rod, a movable ring, and a transmission rod. The anchor rod body is arranged inside the installation hole, a cavity is arranged inside the anchor rod body, an installation block is fixedly arranged on one side inside the cavity, a screw rod is movably arranged in the middle of the inner side of the installation block through a bearing, a plurality of extension rods are evenly movably inserted on the outer surface of the anchor rod body, a plurality of movable rings are movably screwed on the outer surface of the screw rod through threads, and a transmission rod is movably arranged on the outer surface of the movable ring through a rotating shaft.

[0006] Preferably, one end of the transmission rod (9) close to the extension rod is movably connected to the extension rod through a rotating shaft. By moving the movable ring along the screw rod, the extension rod can be pushed to open to both sides under the action of the transmission rod, so that the extension rod can be inserted into the soil layer around the installation hole, thereby effectively improving the fixing stability of the anchor rod.

[0007] Preferably, a convex tooth is fixedly arranged at one end of the extension rod away from the transmission rod. The convex tooth can facilitate the embedding of the extension rod into the surrounding soil layer, thereby further improving the fixing stability of the extension rod and the anchor rod.

[0008] Preferably, a first fixing block is fixedly arranged at one end of the anchor rod. The wrench is sleeved on the outer surface of the first fixing block, which can play a role in fixing the anchor rod. Subsequently, when the screw rod rotates, the anchor rod will not rotate along with it.

[0009] Preferably, a second fixing block is fixedly arranged at one end of the screw rod close to the first fixing block. The socket wrench can be connected through the second fixing block, and then the electric wrench can be linked to drive the screw rod to rotate.

[0010] Preferably, a mounting plate is fixedly arranged on the outer surface of the first fixing block, and fixing holes are respectively arranged at the four corners of the outer surface of the mounting plate. The connection and fixation of the metal protection net can be facilitated through the mounting plate and the fixing holes.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. After the anchor rod of the present utility model is inserted into the installation hole, the wrench is sleeved on the surface of the first fixing block to ensure that the anchor rod does not rotate. Then, the socket wrench can be connected through the second fixing block, and then the electric wrench can be linked to drive the screw rod to rotate. When the screw rod rotates, the rotating ring can be driven to move. When the rotating ring moves in the direction close to the second fixing block, the extension rods can be pushed away from each other through the transmission rod, so that the convex teeth and the extension rods can be stuck into the soil layer around the installation hole, and the extension rods and the convex teeth can form barbs, thereby effectively improving the fixing stability of the anchor rod. Once the anchor rod is stable, the subsequent metal protection net will also be fixed stably, thus providing a better support effect.

[0013] 2. The operation of the present utility model is simple and not complex. It only needs to be inserted into the installation hole like the anchor rod in the prior art, and then fix the anchor rod and rotate the screw rod, without complex operations, so it is convenient for popularization and use.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a civil engineering slope 1 support device, including a slope 1, mounting holes 2 are opened on the surface of the slope 1, and a fixing mechanism for fixing a protective net is arranged inside the mounting holes 2. The fixing frame includes a bolt body 3, a cavity 4, a mounting block 5, a screw 6, an extension rod 7, a movable ring 8, and a transmission rod 9. A bolt body 3 is arranged inside the mounting hole 2, a cavity 4 is arranged inside the bolt body 3, a mounting block 5 is fixedly arranged on one side inside the cavity 4, a screw 6 is movably arranged in the middle of the inner side of the mounting block 5 through a bearing, a plurality of extension rods 7 are evenly movably inserted through the outer surface of the bolt body 3, a plurality of movable rings 8 are movably screwed on the outer surface of the screw 6 through threads, and a transmission rod 9 is movably arranged on the outer surface of the movable ring 8 through a rotating shaft.

[0021] One end of the transmission rod (9) close to the extension rod 7 is movably connected to the extension rod 7 through a rotating shaft. By moving the movable ring 8 along the screw 6, the extension rod 7 can be pushed to open to both sides under the action of the transmission rod 9, so that the extension rod 7 can be inserted into the soil layer around the inner periphery of the mounting hole 2, thereby effectively improving the fixing stability of the bolt.

[0022] A convex tooth 10 is fixedly arranged at one end of the extension rod 7 away from the transmission rod 9. Through the convex tooth 10, the extension rod 7 can be conveniently embedded into the surrounding soil layer, thereby further improving the fixing stability of the extension rod 7 and the bolt.

[0023] One end of the bolt body 3 is fixedly provided with a first fixing block 11. By sleeving a wrench on the outer surface of the first fixing block 11, the bolt can be fixed. Subsequently, when the screw rod 6 is rotated, the bolt will not be driven to rotate together;

[0024] One end of the screw rod 6 close to the first fixing block 11 is fixedly provided with a second fixing block 12. The socket wrench can be connected through the second fixing block 12, and then the electric wrench can be linked to drive the screw rod 6 to rotate;

[0025] The outer surface of the first fixing block 11 is fixedly provided with a mounting plate 13. Fixing holes 14 are respectively opened at the four corners of the outer surface of the mounting plate 13. The connection and fixation of the metal protection net can be facilitated through the mounting plate 13 and the fixing holes 14.

[0026] Working principle: When using this device, a plurality of mounting holes 2 are opened on the slope 1. The mounting holes 2 are evenly spaced. Subsequently, the bolt is inserted into the mounting hole 2. At this time, the extension rod 7 is in a contracted state and is accommodated inside the bolt, so that the bolt can be easily inserted into the mounting hole 2. Subsequently, after the bolt is inserted into the mounting hole 2, a wrench is sleeved on the surface of the first fixing block 11 to ensure that the bolt does not rotate. Then, the socket wrench can be connected through the second fixing block 12, and then the electric wrench can be linked to drive the screw rod 6 to rotate. When the screw rod 6 rotates, it can drive the rotating ring to move. When the rotating ring moves in the direction close to the second fixing block 12, the extension rods 7 can be pushed away from each other and opened through the transmission rod 9, so that the convex teeth 10 and the extension rods 7 can be stuck into the soil layer around the inner circumference of the mounting hole 2, so that the extension rods 7 and the convex teeth 10 can form barbs, thereby effectively improving the fixing stability of the bolt. Then, grouting is carried out into the cavity 4 of the bolt inside the mounting hole 2. After the cement slurry solidifies, the metal protection can be fixed through the mounting plate 13 and the fixing holes 14. In this way, the connection stability between the bolt and the hole can be increased, thereby improving the installation stability of the subsequent slope protection net and improving the subsequent protection effect.
