Description

Technical Field

[0001] The present invention relates to the technical field of roadway floor heave prevention, and particularly relates to an anchor cable shed for supporting roadway surrounding rock to prevent floor heave. Background Technique

[0002] Floor heave refers to the phenomenon that the rock layer at the roadway floor bulges upward due to various factors in a roadway or underground project. The in-situ stress around the roadway is one of the main reasons for floor heave. In deep mining or areas with complex geological structures, high in-situ stress will cause the floor rock layer to be squeezed. When the stress exceeds the bearing capacity of the rock layer, the rock layer will undergo plastic deformation, resulting in floor heave. Floor heave is usually controlled by an anchor cable shed. In the prior art, when some areas of the shed frame are damaged and need to be replaced, the entire shed frame needs to be demolished, which is rather cumbersome and involves a large amount of work. Summary of the Invention

[0016] Specifically: when the device starts to be used, drill into the stable rock formation below the roadway floor, connect the other end of the anchor cable body 7 to the stable rock formation, then connect the connection assembly 6 to the cross connection frame 5 installed on the inner wall of the intermediate groove 101, then place the shed frame body 1 at the bottom of the roadway, install the mounting block 3 on another shed frame body 1 into the mounting groove 2 opened on the previously placed shed frame body 1, repeat the above operation to assemble and connect multiple shed frame bodies 1 together. The rock formation of the roadway floor is lifted upward by the tension of the anchor cable body 7 to limit the upward bulging and deformation of the floor rock formation. At the same time, the tension is evenly transmitted to the floor rock formation through the shed frame body 1, so that the device can control the floor heave phenomenon. The device is assembled together by multiple shed frames. When one or more shed frames are damaged and need to be replaced, only the damaged shed frame needs to be removed and replaced, making the disassembly and replacement of the device more convenient and fast, and making the device more perfect.

[0017] In one embodiment, a first bolt 4 is threadedly embedded on the surface of the mounting groove 2, the number of the first bolts 4 is two, and the surface of the first bolts 4 is threadedly embedded in the inner wall of the mounting block 3.

[0018] Specifically: by threadedly embedding the two first bolts 4 on the surface of the mounting groove 2 into the inner wall of the mounting block 3, after multiple shed frame bodies 1 are assembled together, by tightening the first bolts 4, the device can be assembled together more stably, making the device more perfect.

[0019] In one embodiment, the bottom of the top plate 601 is installed on the top of the cross connection frame 5, the top of the connection column 602 is fixedly installed at the bottom of the top plate 601, the number of the connection columns 602 is four, the top of the mounting bottom plate 603 is installed at the other end of the connection column 602, a second bolt 9 is threadedly embedded on the surface of the top plate 601, the number of the second bolts 9 is four, the surface of the second bolts 9 is embedded in the inner wall of the connection column 602, and the other end of the second bolts 9 is threadedly embedded in the interior of the mounting bottom plate 603.

[0020] Specifically: the top plate 601 is located on the top of the cross connecting frame 5, and the connecting column 602 fixedly installed at the bottom of the top plate 601 is inserted into the surface of the cross connecting frame 5. By rotating the bolt 9, the bottom of the bolt 9 is screwed into the inside of the mounting base plate 603, so that the connecting assembly 6 is connected to the cross connecting frame 5 installed on the inner wall of the middle groove 101, and the anchor cable body 7 installed at the bottom of the mounting base plate 603 is stably connected to the scaffolding body 1, making the device more perfect.

[0021] In one embodiment, a mounting shell 8 is fixedly mounted on the surface of the mounting base plate 603 , and the other end of the connecting column 602 is embedded in the inner wall of the mounting shell 8 .

[0022] Specifically: by embedding the other end of the mounting base plate 603 into the inner wall of the mounting shell 8 fixedly mounted on the surface of the mounting base plate 603, the mounting base plate 603 can be more accurately positioned when it is mounted on the other end of the connecting column 602 through bolts 9, making the connection more convenient and accurate and the device more perfect.

[0023] In one embodiment, slots 102 are opened on the surface of the scaffolding body 1, and the number of slots 102 is four. A ground plug 10 is movably embedded in the inner wall of the slot 102. Bolts 3 11 are threadedly embedded at equal intervals on the surface of the ground plug 10. The surface thread at the bottom of the bolt 3 11 is embedded inside the scaffolding body 1.

[0024] Specifically: During use of the device, after multiple scaffolding bodies 1 are installed and assembled, the ground plug 10 is inserted into the inner wall of the slot 102 and pressed downward so that the bottom of the ground plug 10 is embedded in the ground, so that the scaffolding body 1 can be stably installed on the ground, and the bolt 11 is screwed into the interior of the scaffolding body 1 so that the ground plug 10 can be stably installed on the scaffolding body 1, so that the scaffolding can be prevented from displacement or shaking due to the squeezing of the rock strata around the tunnel and the upward thrust generated by the bottom drum. At the same time, the tension of the anchor cable and the pressure of the rock strata around the tunnel that the scaffolding is borne by can be transmitted to the deeper soil or rock strata underground through the ground plug 10, thereby expanding the dispersion range of the pressure, thereby enhancing the bearing capacity of the bottom plate rock strata, better resisting the deformation of the bottom drum, and making the device more perfect.

[0025] Working principle: When the device starts to be used, it drills into the stable rock formation below the roadway floor. The other end of the anchor cable body 7 is connected to the stable rock formation. Then, the connecting column 602 fixedly installed at the bottom of the roof 601 is inserted onto the surface of the cross connecting frame 5. By rotating the second bolt 9, the bottom of the second bolt 9 is screwed into the inside of the installation base plate 603 for screwing in, so that the connecting assembly 6 is connected to the cross connecting frame 5 installed on the inner wall of the middle groove 101, and the anchor cable body 7 installed at the bottom of the installation base plate 603 is connected to the shed body 1. Then, the shed body 1 is placed at the bottom of the roadway, and the installation block 3 on another shed body 1 is installed in the installation groove 2 opened on the previously placed shed body 1. Repeat the above operations to assemble and connect multiple shed bodies 1 together. The rock formation of the roadway floor is lifted upward by the tension of the anchor cable body 7 to limit the upward bulging and deformation of the floor rock formation. At the same time, the tension is evenly transmitted to the floor rock formation through the shed body 1, so that the device can control the floor heave phenomenon. The device is assembled by multiple shed bodies. When one or more shed bodies are damaged and need to be replaced, only the damaged shed body needs to be removed and replaced, making the disassembly and replacement of the device more convenient and fast, and making the device more perfect. During the use of the device, after multiple shed bodies 1 are installed and combined, the ground plug 10 is inserted into the inner wall of the slot 102 and pressed down, so that the bottom of the ground plug 10 is embedded in the ground, and the shed body 1 can be stably installed on the ground. By rotating the third bolt 11 and screwing it into the inside of the shed body 1, the ground plug 10 can be stably installed on the shed body 1, so as to prevent the shed from shifting or shaking due to the extrusion of the surrounding rock formation of the roadway and the upward thrust generated by the floor heave. At the same time, the pressure borne by the shed from the anchor cable tension and the pressure of the surrounding rock formation of the roadway can be transmitted to the deeper soil layer or rock formation underground through the ground plug 10, expanding the dispersion range of the pressure, thereby enhancing the bearing capacity of the floor rock formation and better resisting the floor heave deformation, making the device more perfect.
