Description

Technical Field

[0001] The utility model relates to the technical field of coal gangue slope protection, and particularly relates to a coal gangue slope protection component. Background Technique

[0002] A coal gangue slope refers to a slope formed by the accumulation of coal gangue generated during coal mining and coal washing processes. Coal gangue is a solid waste in the processes of coal mining and coal washing, mainly composed of components such as Al2O3 and SiO2, and contains a certain amount of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3, and trace elements. These coal gangues form slopes during the accumulation process. If not properly managed, a series of environmental problems may be brought about.

[0003] In addition, due to the widespread existence of coal gangue slopes, once a landslide occurs, it not only threatens the lives of nearby residents but also has a serious impact on the environment. Therefore, it is necessary to analyze and study the stability of coal gangue slopes and take appropriate protective measures, such as building retaining walls, etc. These measures aim to ensure the stability of coal gangue mountains, prevent the occurrence of landslide disasters, and protect the surrounding environment and human safety.

[0004] For example, the Chinese invention patent with the application number 202110696819.6 provides a method for shallow reinforcement and ecological restoration of coal gangue slopes, and discloses that most coal gangue slopes have a relatively steep slope. The strongly weathered coal gangue is prone to disintegration when encountering water, and the coal gangue after spontaneous combustion is weakly acidic, with a high heavy metal content and weak water retention capacity, and cannot provide a good growth environment for plants. The soil sprayed by using the traditional spraying method has poor stability on the coal gangue slope, is easily washed away by rainwater, and due to the influence of the properties of the coal gangue itself, the plant growth is poor, and it is difficult to achieve the effect of ecological slope protection.

[0005] However, based on the original soil spraying technology, through the synergistic effect of polymer curing agents and soil curing agents, although reinforcement can be achieved, the reinforcement period is relatively long, the process is complex, and at the same time, curing the coal gangue slope by chemical means is likely to change its own properties and affect subsequent use. Therefore, it cannot meet the actual curing requirements. Content of the Utility Model

[0006] The purpose of the utility model is to provide a coal gangue slope protection component to solve the problem that the current chemical curing of coal gangue slopes cannot meet the actual curing requirements.

[0010] Further limited, a clamping groove is also opened on the connection block, and a clamping block that is matched with the clamping groove is arranged on the periphery of the coal gangue slope protection piece.

[0011] Further limited, a protection net is arranged on the coal gangue slope protection piece, and the protection net is detachably connected to the coal gangue slope protection piece.

[0012] Further limited, a locking pin is arranged on the periphery of the protection net, and a locking rod that is matched with the locking pin is arranged on the coal gangue slope protection piece.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-6 , a coal gangue slope protection component provided by the present utility model includes a coal gangue slope protection component 1 and a connection block 4. After the coal gangue slope protection component 1 and the connection block 4 are spliced, they cover the coal gangue slope for protecting the coal gangue slope.

[0028] Meanwhile, an anchor rod 14 is provided on the connection block 4. The anchor rod 14 is arranged along the axis of the connection block 4. The bottom end of the anchor rod 14 passes through the connection block 4 and inserts into the coal gangue slope, which is used to improve the stability of the coverage of the connection block 4 and the coal gangue slope protection member 1, and further improve the stability of the coal gangue slope. Thus, the coal gangue slope protection member 1 and the anchor rod 14 are used to prevent the coal gangue slope from sliding, meeting the protection requirements of the coal gangue slope.

[0029] Furthermore, in actual use, the number of the coal gangue slope protection members 1 and the number of the connection blocks 4 are both multiple. The coal gangue slope protection members 1 are spliced on the periphery of the connection blocks 4. Preferably, the coal gangue slope protection members 1 are arranged circumferentially around the center of the connection blocks 4.

[0030] For example, the coal gangue slope protection member 1 is a regular octagon and the connection block 4 is a square. At this time, each side of the connection block 4 is spliced with a coal gangue slope protection member 1, and the left and right adjacent coal gangue slope protection members 1 and the upper and lower adjacent coal gangue slope protection members 1 are in contact with each other.

[0031] Furthermore, an installation hole 12 is opened on the connection block 4. The installation hole 12 is opened at the middle position of the connection block 4, so that the installation hole 12 is coaxially arranged with the connection block 4, and the anchor rod 14 passes through the installation hole 12.

[0032] In order to improve the reliability of the installation of the anchor rod 14 and the installation hole 12, a plurality of positioning grooves 13 are arranged on the outer side of the installation hole 12. The positioning grooves 13 are communicated with the installation hole 12. The plurality of positioning grooves 13 are circumferentially arranged on the periphery of the installation hole 12, and the depth of the positioning grooves 13 is less than the thickness of the connection block 4.

[0033] Meanwhile, a positioning convex block 15 is arranged on the periphery of the top of the anchor rod 14. The positioning convex block 15 cooperates with the positioning groove 13. After the anchor rod 14 is inserted into the coal gangue slope, the positioning convex block 15 can cooperate with the corresponding positioning groove 13 to prevent the anchor rod 14 from sliding into the coal gangue slope. At the same time, the cooperation of the positioning convex block 15 and the connection block 4 also facilitates the removal of the anchor rod 14, reducing the operation difficulty and meeting the actual protection requirements.

[0034] The number of the positioning grooves 13 and the number of the positioning convex blocks 15 can both be selected as four. The four positioning grooves 13 are circumferentially arranged around the center of the installation hole 12, and the positioning convex blocks 15 are circumferentially arranged around the center of the anchor rod 14, and both are preferably arranged at equal intervals.

[0035] A clamping groove 5 is also opened on the connection block 4. The clamping groove 5 is opened on the side of the connection block 4 and is located outside the positioning groove 13. At the same time, a clamping block 2 is arranged on the periphery of the coal gangue slope protection member 1. The clamping block 2 cooperates with the clamping groove 5 to realize the splicing of the coal gangue slope protection member 1 and the connection block 4.

[0036] The number of card slots 5 can be selected as four. Similarly, the number of card blocks 2 is four. The four card slots 5 are respectively arranged around the connecting block 4, and the four card blocks 2 are arranged in an equidistant circular pattern around the center of the coal gangue slope protection member 1.

[0037] The connecting block 4 can fix a total of four groups of coal gangue slope protection members 1 on the upper left, upper right, lower left, and lower right. By setting closely arranged concrete members on the slope surface, the stability and anti-slip performance of the slope can be increased. The setting of the connecting block 4 improves the connection degree between the coal gangue slope protection members 1, making the coal gangue slope protection members 1 connect tightly with each other, bear force on each other, not easy to slip, and stable and reliable.

[0038] Furthermore, a protective net 3 is provided on the coal gangue slope protection member 1. The protective net 3 is arranged at the middle position of the coal gangue slope protection member 1, and the coal gangue slope protection member 1 is detachably connected to the protective net 3.

[0039] The protective net 3 can be detachably connected to the coal gangue slope protection member 1 by means of bonding, snap connection, or magnetic attraction.

[0040] Preferably, a locking rod 6 is provided on the coal gangue slope protection member 1, and a locking pin 10 is provided on the periphery of the protective net 3. The number of locking pins 10 is the same as the number of locking rods 6, so that the locking pins 10 and the locking rods 6 are in one-to-one correspondence and snap-connected during use.

[0041] Specifically, a rotating shaft 9 is provided on the periphery of the protective net 3. One end of the locking pin 10 is rotatably connected to the protective net 3 through the rotating shaft 9. An arc groove 11 is formed at the other end of the locking pin 10, and the arc groove 11 is snap-connected to the locking rod 6. The locking rod 6 is located outside the protective net 3. Thus, through the cooperation of the locking pin 10 and the locking rod 6, the disassembly and assembly of the protective net 3 are facilitated.

[0042] To ensure the reliable installation of the protective net 3, a locking piece 7 is provided on the locking rod 6. The locking piece 7 is threadedly connected to the locking rod 6. The locking piece 7 can be selected as a nut, which is used to improve the connection reliability between the locking pin 10 and the locking rod 6 after the locking pin 10 is snap-connected to the locking rod 6.

[0043] When the protective net 3 is installed on the surface of the coal gangue slope protection member 1, the protective net 3 can intercept small gravel rolling down the slope, preventing the gravel from rolling down and injuring pedestrians, thereby improving the comprehensiveness of the protection.

[0044] Furthermore, through holes 8 are provided at the top and bottom of the coal gangue slope protection member 1; the provision of the through holes 8 enables the rainwater inside the coal gangue slope protection member 1 to flow down from top to bottom and will not accumulate inside the coal gangue slope protection member 1, thereby preventing water accumulation inside the coal gangue slope protection member 1.

[0045] When the embodiment of the present application is in use:

[0046] First, fix the connecting block 4 on the coal gangue slope surface. Pass the anchor rod 14 through the installation hole 12 inside the connecting block 4 and insert it into the coal gangue slope. The positioning convex block 15 at the top of the anchor rod 14 is stuck in the positioning groove 13 to fix the connecting block 4.

[0047] Next, sequentially place the coal gangue slope protection member 1 on the side of the connecting block 4, and snap the clamping block 2 into the clamping groove 5 to splice the coal gangue slope protection member 1 and the connecting block 4. The connecting block 4 can fix the coal gangue slope protection members 1 on its periphery. The setting of the connecting block 4 improves the connection degree between the coal gangue slope protection members 1, making the coal gangue slope protection members 1 connected tightly to each other, bearing force together, not easy to slip, and stable and reliable.

[0048] Then, place the protection net 3 on the surface of the coal gangue slope protection member 1, and then rotate the locking pin 10 so that it is stuck on the locking rod 6 through the arc groove 11. The locking piece 7 limits the locking pin 10 to prevent it from falling off, and then the protection net 3 can be installed on the surface of the coal gangue slope protection member 1. By setting closely arranged concrete members on the slope surface, the stability and anti-slip performance of the slope are increased. Further, the protection net 3 on the surface of the coal gangue slope protection member 1 can intercept small gravels rolling down on the slope to prevent the gravels from rolling down and injuring pedestrians, thereby improving the comprehensiveness of the protection. In addition, the setting of the through hole 8 enables the rainwater inside the coal gangue slope protection member 1 to flow down from top to bottom and will not accumulate inside the coal gangue slope protection member 1, thereby preventing water accumulation inside the coal gangue slope protection member 1.

[0049] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.
