[0002] Roadway floor heave refers to the deformation phenomenon that the rock stratum of the roadway floor bulges upward. This phenomenon is mainly caused by the influence of mining engineering, which leads to the deformation of the rock mass of the roadway roof, floor and two sides and the displacement into the roadway, especially the phenomenon that the floor bulges upward. If the roadway floor heave is not controlled, safety problems such as collapse are likely to occur.
[0003] In the prior art, there is a certain research on the surrounding rock loosening method related to the roof lifting of the main tunnel. Refer to the patent document with the application number 202111054700.5, which discloses a cable bolt support method and cable bolts for controlling roadway floor heave. During the process of controlling roadway floor heave, the drilling layout method is set according to the on-site working conditions; after determining the drilling layout method, the target position is selected for drilling according to the preset rules, and fiberglass grouting cable bolts are installed on the drilling; after the installation of the fiberglass grouting cable bolts is completed, the slurry is selected for grouting and anchoring. The soft floor rock stratum or coal seam is bonded and modified by pumping the slurry, and the bearing capacity of the dense basic floor, the suspension effect of the cable bolt and the bonding effect of the slurry are fully exerted. Through grouting and anchoring at multiple angles and with multiple slurries, the purpose of controlling floor heave is finally achieved.

[0028] The technical solution of the utility model will be further explained below in conjunction with the drawings and embodiments, but the utility model is not limited to the following described embodiments.
[0029] Please refer to Figures 1-5 , an embodiment provided by the utility model: A treatment device for roadway floor heave, including a stainless steel support body 5, a first explosion-proof airbag part 14 and a second explosion-proof airbag part 15.

Stainless steel reinforcements 16 are evenly welded inside the hollow grouting cavity 17 on the outer side wall of the intermediate positioning pipe 18;
[0031] During use, the user can hoist the stainless steel support body 5 into the corresponding roadway floor heave. By using the plug-in fixing piles 9 arranged at the bottom of the outer side grouting pipe groups 7 on both sides of the bottom of the main grouting pipe 2, the bottom of the device can be plugged and fixed to the inner bottom surface of the roadway floor heave. Then, the filling slurry is introduced through the reserved grouting vertical pipe 6 at the top of the main grouting pipe 2. At this time, the slurry will fill the inner part of the roadway floor heave through the outer side grouting pipe groups 7 and the lower slurry outlet 8. After solidification, a reinforced support layer will be formed on the inner wall of the roadway floor heave. Moreover, the filling slurry can also be introduced into the internal middle positioning pipe 18 connected thereto through the reserved grouting vertical pipe 6 at the top of the main grouting pipe 2, and then filled into the internal hollow grouting cavity 17 arranged inside the stainless steel support body 5 through the middle positioning pipe 18. This can ensure that the hollow stainless steel support body 5 is convenient for reducing its own weight to facilitate hoisting operations, and also ensures that the subsequent filling of the slurry into the hollow structure can improve the structural strength and counterweight support effect of the stainless steel support body 5. Furthermore, it enables the device to eliminate the need for manual entry into the roadway floor heave to lay the support layer, thereby enhancing the safety performance of the roadway floor heave treatment effect;
[0032] The first explosion-proof airbag part 14 and the second explosion-proof airbag part 15 are respectively bonded to both ends of the stainless steel support body 5. Flexible air pipes 13 are connected to the tops of the first explosion-proof airbag part 14 and the second explosion-proof airbag part 15, and a manual air valve 12 is installed on the flexible air pipe 13;
[0033] A circular top plate 1 is welded to the top of the stainless steel support body 5;
[0034] Reinforcing traction ropes 3 are evenly installed at the edge of the circular top plate 1, and fixing anchors 4 are fixed to the bottoms of the reinforcing traction ropes 3;
[0035] Connection hooks 10 are fixed to the tops of the reinforcing traction ropes 3, and connection hanging rings 11 matching the connection hooks 10 are arranged on the circular top plate 1;
[0036] During use, the user can utilize the assembly structure formed by the connection hooks 10 and the connection hanging rings 11 to assemble the reinforcing traction ropes 3 of appropriate length at the edge of the circular top plate 1 on the top of the stainless steel support body 5. Subsequently, the fixing anchors 4 at the bottoms of the reinforcing traction ropes 3 are plugged into appropriate positions on the top surface of the roadway floor heave, which can achieve the reinforcement installation of the top of the device and improve the stability;
[0037] The stainless steel support body 5 has a hollow structure;
[0038] A reserved grouting vertical pipe 6 is welded at the middle position of the top of the main grouting pipe 2, and a sealing plug is threadedly connected to the reserved grouting vertical pipe 6;[[ID=2,2]]
[0039] The stainless steel reinforcing ribs 16 are arranged at equal angles inside the hollow grouting cavity 17;
[0040] Anti-explosion airbag parts 14 and 15 are both provided with anti-slip protrusions on their outer side walls.
[0041] When the embodiment of the present application is in use: The user can hoist the stainless steel support body 5 into the corresponding roadway floor heave. By using the plug-in fixing piles 9 arranged at the bottom of the outer side surface grouting pipe groups 7 on both sides of the bottom of the grouting main pipe 2, the bottom of the device and the inner bottom surface of the roadway floor heave are plugged and fixed. Then, the filling slurry is introduced through the reserved grouting vertical pipe 6 at the top of the grouting main pipe 2. At this time, the slurry will be filled into the roadway floor heave through the outer side surface grouting pipe groups 7 and the lower slurry outlet 8. After solidification, a reinforced support layer will be formed on the inner wall of the roadway floor heave. And, the filling slurry can also be introduced into the internal middle positioning pipe 18 communicated therewith through the reserved grouting vertical pipe 6 at the top of the grouting main pipe 2, and then filled into the internal hollow grouting cavity 17 arranged inside the stainless steel support body 5 through the middle positioning pipe 18. This can ensure that the stainless steel support body 5 in a hollow state is convenient for reducing its own weight to facilitate the hoisting operation, and also ensures that the structure strength and the counterweight support effect of the stainless steel support body 5 are improved by filling the slurry into the internal hollow structure subsequently. Furthermore, it makes the device not need to enter the roadway floor heave manually to lay the support layer, improving the safety performance of the roadway floor heave treatment effect. At the same time, the user can open the manual air valves 12 on the corresponding flexible air pipes 13 of the first anti-explosion airbag part 14 and the second anti-explosion airbag part 15, and fill the inside of the first anti-explosion airbag part 14 and the second anti-explosion airbag part 15 with gas through an air pump, so that the first anti-explosion airbag part 14 and the second anti-explosion airbag part 15 bulge and tightly press against the inner wall of the roadway floor heave. This can solve the problems of incomplete support surface and poor support effect caused by the fact that common support structures are not easy to be closely attached to the inner wall of the roadway floor heave. Moreover, by using the elastic buffer effect of the first anti-explosion airbag part 14 and the second anti-explosion airbag part 15, the shock absorption and buffer protection of the device for the roadway floor heave are also improved, further optimizing the support function. In addition, the user can use the assembly structure composed of the connection hook 10 and the connection hanging ring 11 to assemble the reinforced traction rope 3 with an appropriate length at the edge of the annular top plate 1 at the top of the stainless steel support body 5. Subsequently, the fixing anchor 4 at the bottom of the reinforced traction rope 3 is plugged into an appropriate position on the top surface of the roadway floor heave, which can realize the reinforced installation of the top of the device and improve the stability.
