Description

Technical Field

[0001] This utility model relates to the field of slope construction technology, and in particular to a safety device for highway slope protection construction. Background Technology

[0002] With the rapid development of the transportation industry, the scale of highway construction is expanding daily, especially in mountainous areas or regions with complex geological conditions. Slope stability and safety have become crucial issues in highway construction. To ensure traffic safety and protect the environment along highways, slope protection has become an indispensable part of highway engineering. The main purpose of slope protection is to prevent landslides, collapses, and other disasters, while also ensuring the restoration of slope vegetation and ecological balance.

[0003] Traditional slope protection measures mainly include structures such as protective netting, soil nailing walls, anchor bolts, and lattice beams, as well as ecological measures such as vegetation slope protection. However, these slope protection measures have long construction times and low installation efficiency, making them unsuitable for rapid construction. Utility Model Content

[0004] The purpose of this utility model is to provide a safety device for highway slope protection construction. It prevents landslides by setting up protective blocks and fixing blocks, while the first protective net and the second fireproof net are used to prevent falling rocks. The installation is simple and convenient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A safety device for highway slope protection construction includes a protective block, a fixing block on the side of the protective block near the slope, the fixing block being fixed to the ground by a fixing rod, a first protective net on the side of the protective block near the slope, the end of the first protective net away from the protective block being fixed to the slope, a second protective net on the upper end of the fixing block, the end of the second protective net away from the fixing block being fixed to the slope, and the first and second protective nets being fixed to the slope at equal intervals from top to bottom.

[0007] By adopting the above technical solution, the protective blocks and fixing blocks are fixed at the bottom of the slope to block the soil and rocks caused by the landslide. Then, the slope is protected by the first and second protective nets to prevent the falling rocks from falling directly. After being buffered by the first and second protective nets, the rocks fall onto the fixing blocks, which further compress and fix the fixing blocks.

[0008] A further feature of this invention is that the side of the protective block away from the slope has a downward-sloping surface.

[0009] By adopting the above technical solution, the contact area between the protective block and the ground is increased, ensuring the stability and strength of the protective block.

[0010] A further feature of this invention is that the fixing block has a fixing hole, and the fixing rod is inserted into the fixing hole and connected to the ground.

[0011] By adopting the above technical solution, the fixing block is fixed by a fixing rod, which prevents the fixing block from moving, making it simple and convenient.

[0012] A further feature of this invention is that the protective block and the fixing block are integrally formed.

[0013] By adopting the above technical solution, the strength of the protective block and the fixing block is guaranteed.

[0014] A further feature of this invention is that both the first protective net and the second protective net are fixed to the slope by anchor bolts.

[0015] By adopting the above technical solution, the anchor bolt fixing effect is good.

[0016] A further feature of this invention is that the anchor bolt includes a sleeve, a screw, a connector, a sealing ring, and a ball bearing. The sleeve is inserted into the slope, and multiple mounting holes are provided on the side wall of the sleeve. The ball bearing is interference-fitted into the mounting holes, and the diameter of the ball bearing is larger than the wall thickness of the mounting hole. One end of the screw is pointed and inserted into the sleeve. The screw and the sleeve are threaded together. The other end of the screw is connected to the connector. The sealing ring is located on the side of the connector near the screw and is used in conjunction with the sleeve. The connector is detachably connected to the first protective net and the second protective net.

[0017] By adopting the above technical solution, holes are first drilled in the slope, then the sleeve is inserted into the drilled holes, and then the screw is inserted into the sleeve to push the ball outward, thereby fixing the sleeve and the slope.

[0018] In summary, this utility model has the following beneficial effects:

[0019] Firstly, the protective block and fixing block in this utility model are used to prevent landslides, while the first protective net and the second fireproof net are used to prevent falling rocks. Landslides and falling rocks will fall on the fixing block, further pressing the fixing block, and the installation is convenient and quick.

[0020] Secondly, in this utility model, when the anchor rod is inserted into the sleeve through the screw, the ball part is pushed out of the installation hole, allowing the ball to embed into the rock, so that the anchor rod is firmly fixed on the slope, and the fixing is simple and convenient.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] An embodiment of a safety device for highway slope protection construction includes a protective block 1. A fixing block 2 is located on the side of the protective block 1 closest to the slope 5, and the side of the protective block 1 furthest from the slope 5 has a downward-sloping surface. The fixing block 2 is fixed to the ground by a fixing rod 3. A fixing hole 21 is provided on the fixing block 2, and the fixing rod 3 is inserted into the fixing hole 21 and connected to the ground. The protective block 1 and the fixing block 2 are precast concrete blocks, manufactured as a single piece, and can be placed directly next to the slope 5 and then fixed by the fixing rod 3 to prevent displacement. When a landslide occurs on the slope 5, the protective block 1 acts as a barrier, while the soil and rocks generated by the landslide press down on the fixing block 2, making the fixing block 2 more secure.

[0029] A first protective net 4 is installed on the side of the protective block 1 closest to the slope 5. The end of the first protective net 4 away from the protective block 1 is fixed to the slope 5. A second protective net 6 is installed on the upper end of the fixed block 2. The end of the second protective net 6 away from the fixed block 2 is fixed to the slope 5. The first protective net 4 and the second protective net 6 are fixed to the slope 5 at equal intervals from top to bottom. Both the first protective net 4 and the second protective net 6 are fixed to the slope 5 by anchor bolts 7. During the falling of rocks, the first protective net 4 and the second protective net 6 can mitigate the fall of rocks, allowing them to land on the fixed block 2 and the protective block 1.

[0030] The anchor bolt 7 includes a sleeve 71, a screw 72, a connector 73, a sealing ring 74, and ball bearings 75. The sleeve 71 is inserted into the slope 5. Multiple mounting holes 76 are formed on the side wall of the sleeve 71. The ball bearings 75 are interference-fitted into the mounting holes 76, and their diameter is larger than the wall thickness of the mounting holes 76. One end of the screw 72 is pointed and inserted into the sleeve 71, with a threaded connection between the screw 72 and the sleeve 71. The other end of the screw 72 is connected to the connector 73. The sealing ring 74 is located on the side of the connector 73 near the screw 72 and works in conjunction with the sleeve 71. The connector 73 is detachably connected to the first protective net 4 and the second protective net 6. The anchor bolt 7 securely fixes itself to the slope 5 by inserting the screw 72 into the sleeve 71, during which the ball bearings 75 are pushed out of the mounting holes 76. The ball bearing 75 is fixed in the mounting hole 76 by interference fit, so that when the sleeve 71 is inserted into the slope 5, the ball bearing 75 will not protrude from the sleeve 71 and affect the installation of the sleeve 71.

[0031] Instructions for use: Arrange the precast blocks made of protective block 1 and fixing block 2 next to the slope 5 and fix them with fixing rod 3. Then install the second protective net 6 and finally install the first protective net 4. When installing the second protective net 6 and the first protective net 4, first drill holes in the slope 5, then insert the sleeve 71 into the drilled holes, insert the screw 72 into the sleeve 71, and push out the ball bearing 75 during the insertion of the screw 72 to form a fixation. Finally, fix the first protective net 4 and the second protective net 6 to the connector 73.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
