Description

Technical Field

[0001] This utility model relates to the field of blasting protection technology, specifically a slope protection wall to prevent blasted rocks from scattering. Background Technology

[0002] During blasting operations, the work site is prone to the danger of flying debris, posing a threat to the lives of nearby operators and posing a significant operational risk. In such cases, it is often necessary to shield and protect these flying debris. The current shielding method usually involves using a retaining wall for direct shielding. However, under long-term impact, the surface of the retaining wall may crack, and it may even collapse. Therefore, we propose a slope main retaining wall to prevent the scattering of blasted debris and solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a slope protection wall that prevents blasted rocks from scattering, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a slope protection wall to prevent blasted rock fragments from scattering, comprising a slope body and a cement ground set on one side of the slope body, and further comprising:

[0005] A protective wall is fixedly connected to the top of the cement ground, and a guide structure and a drive structure used in conjunction with the protective wall are installed on one side of the protective wall;

[0006] A baffle is rotatably connected to the top of the protective wall, and a second fixing block is fixedly connected to both sides of the bottom of the baffle;

[0007] A protective net is installed between the baffle and the concrete ground, and a third fixing block is fixed to the front and back of both sides of the bottom of the protective net. A first bolt and a second bolt are respectively installed through the inside of the top of the protective net and the inside of the third fixing block. The other ends of the first bolt and the second bolt are respectively threaded to the inside of the second fixing block and the inside of the concrete ground.

[0008] Preferably, the guide structure includes a fixed plate fixedly connected to the top of the baffle, a steel wire rope fixedly connected to the top of the fixed plate, the top of the protective wall fixedly connected to a first fixed block, a guide wheel rotatably connected between the inner walls of the top of the first fixed block, and the surface of the guide wheel being in contact with the steel wire rope.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 As shown, a slope protection wall for preventing blasted rock fragments from scattering includes a slope body 1 and a cement ground 2 set on one side of the slope body 1. A protection wall 3 is fixedly connected to the top of the cement ground 2. Supports 12 are fixed to the left and right sides of one side of the protection wall 3 by bolts. The bottom of the supports 12 is fixed to the cement ground 2. By setting the supports 12, when the protection wall 3 is impacted, the supports 12 can help disperse part of the force, reduce the wall cracking caused by excessive local force, and thus better maintain the structural integrity and impact resistance of the protection wall 3. A guide structure 4 is installed on one side of the protection wall 3. The guide structure 4 includes a fixed plate 44 fixedly connected to the top of the baffle 5. A steel wire rope 43 is fixedly connected to the top of the fixed plate 44. The top of the protection wall 3 is fixedly connected to a first fixed block 41. A guide wheel 42 is rotatably connected between the inner walls of the top of the first fixed block 41, and the surface of the guide wheel 42 is in contact with the steel wire rope 43.

[0022] By setting the guide structure 4, the guide wheel 42 can provide support for the wire rope 43, thereby preventing the wire rope 43 from shortening its service life due to excessive wear. When the baffle 5 is rotated, the drive structure 11, in conjunction with it, can apply force to the wire rope 43, enabling the wire rope 43 to drive the baffle 5 to deflect at an angle. The drive structure 11, which works in conjunction with it, includes connecting plates 111 fixedly connected to the front and rear sides of one side of the protective wall 3. A connecting post 112 is rotatably connected between the two connecting plates 111. One end of the connecting post 112 passes through the connecting plate 111 and is fixedly connected to a torsion disc 113. A fixing bolt 114 is threaded into the interior of one connecting plate 111. The other end of the wire rope 43 is wound around the surface of the connecting post 112. Several limiting holes are opened around the surface of the connecting post 112 to cooperate with one end of the fixing bolt 114. The configuration of 1 allows the operator to apply force to the torsion plate 113, which in turn drives the connecting column 112 to rotate, thereby winding the wire rope 43. After the wire rope 43 is wound to a suitable distance, the fixing bolt 114 can be screwed into the inner side of the connecting plate 111, so that the other end of the fixing bolt 114 enters the limiting hole on the surface of the connecting column 112, thereby preventing the wire rope 43 from being unwound at will. The top of the protective wall 3 is rotatably connected to the baffle 5, and the bottom sides of the baffle 5 are fixedly connected to the second fixing block 6. A protective net 8 is set between the baffle 5 and the cement ground 2, and the front and rear sides of the bottom sides of the protective net 8 are fixed to the third fixing block 9. The top sides of the protective net 8 and the interior of the third fixing block 9 are respectively provided with the first bolt 7 and the second bolt 10. The other ends of the first bolt 7 and the second bolt 10 are respectively threadedly connected to the interior of the second fixing block 6 and the interior of the cement ground 2.

[0023] The bottom of the protective wall 3 is trapezoidal on one side, wider at the bottom and narrower at the top. This design increases the contact area between the bottom of the protective wall 3 and the surface of the cement floor 2, which enhances the overall impact resistance. This makes the protective wall 3 less likely to be damaged due to force imbalance when subjected to lateral impact. At the same time, the trapezoidal bottom of the protective wall 3 allows the impact force to be evenly transmitted to the cement floor 2 foundation through the widened bottom, which helps to reduce the excessive local stress on the bottom of the wall, thereby reducing the risk of damage and cracking and extending its service life.

[0024] Working principle: Before the blasting operation, the operator applies force to the fixing bolt 114, causing it to detach from the connecting plate 111 and the connecting column 112. Simultaneously, the operator twists the torsion disc 113, causing the connecting column 112 to rotate and the wire rope 43 to unwind. Guided by the guide wheel 42, the wire rope 43 pulls the baffle 5. Due to its own weight, the baffle 5 tilts. Once the baffle 5 reaches the appropriate position, the operator stops applying force to the torsion disc 113 and reinserts the fixing bolt 114 into the connecting plate 111 and the connecting column 112 for fixation. Then, the operator secures the top of the protective net 8 to the second fixing block 6 using the first bolt 7. Finally, the protective net 8 is then... The bottom of the protective net 8 is fixed to the third fixing block 9 using the second bolt 10. Then, the operator pulls out the fixing bolt 114 again and applies force to the twisting disc 113, causing the connecting column 112 to rotate and the wire rope 43 to be wound up. The baffle 5 is subjected to force and flips, pulling the protective net 8 to unfold. When the baffle 5 flips to the appropriate position, the operator stops applying force and inserts the fixing bolt 114 to fix it. During blasting, the protective wall 3 and the protective net 8 can effectively prevent flying rocks from splashing to the outside or around the slope. When the protective net 8 is replaced due to repeated impacts, the above operation can be repeated for replacement to facilitate subsequent protection.
