Figure 3 The front structure of the fluid-filled construction method for filling the grooves and the tunnel walls is shown. Figure 4 The side structure of the filling in the groove and the tunnel wall in the fluid filling construction method is shown.

[0042] Please refer to Figures 1 to 4 , the fluid filling construction method of the present invention comprises the following steps: S1: installing the skeleton on the tunnel of the pre-filled stope;

[0043] S2: abutting a plurality of card slots against the lane wall through the frame, wherein there is an irregular gap between the plurality of card slots and the lane wall, and a plug-in opening is provided on the card slot;

[0044] S3: filling the gap with liquid A and liquid B through the plug-in port, wherein the liquid A and liquid B are mixed in the gap to form a filling body;

[0045] S4: installing a plug plate on the plug plate opening to prevent the filling body from overflowing from the gap;

[0046] S5: After the filling body solidifies, the frame is disassembled and recycled to complete the fluid filling construction.

[0047] Furthermore, a sealing plate is provided on the skeleton 1, and the sealing plate is used to prevent the solution of the filling body from leaking from the gaps of the skeleton 1. The sealing plate can ensure the filling effect. There will be gaps between the various parts of the skeleton 1 when connected, and these gaps affect the stability and safety of the skeleton 1. The use of the sealing plate not only improves the compactness of the filling, but also effectively improves the stability of the skeleton 1 during the filling process, and also ensures the sealing during the filling process.

[0048] Further, in step S1, the skeleton is installed on the tunnel of the pre-filled stope, including the following steps: fixing the skeleton to the tunnel wall by a screw; fixing the skeleton to the ground of the tunnel by a support rod. One end of the screw 3 is rotated and set on the skeleton 1, and the other end is fixed on the tunnel wall to fix the skeleton 1; a support rod 4 is arranged on the skeleton 1, and one end of the support rod 4 is arranged on the skeleton 1, and the other end is fixed on the bottom surface of the tunnel; wherein the support rod 4 is used to strengthen the stability of the skeleton 1. By rotating the screw 3, the screw 3 can be abutted against the tunnel wall, so as to achieve the tightening and adjustment of the skeleton 1 by the screw 3. The setting of the screw 3 not only enhances the stability of the skeleton 1, but also makes the installation and disassembly process of the skeleton 1 simpler and faster. At the same time, the material and size of the screw 3 are adjusted according to the construction requirements on site to ensure that it can withstand the complex geological conditions and long-term load in the tunnel. The setting of the support rod 4 further enhances the overall stability of the skeleton 1, so that the skeleton 1 can better withstand various loads and deformations in the tunnel. The number and position of the support rods 4 are reasonably arranged to ensure that the load can be evenly distributed to avoid damage to the frame 1 due to excessive local stress.

[0049] Furthermore, the card slot 2 is a U-shaped slot. A slot structure opposite to the card slot 2 is provided on the skeleton 1, so that the card slot can be conveniently connected to the skeleton 1. The card slot 2 is arranged around the tunnel wall, and is abutted against the tunnel wall through the skeleton 1, and a gap is formed between the card slot 2 and the tunnel wall. The design of the U-shaped slot is not only convenient for the installation and removal of the card slot 2, but also can effectively prevent the deformation and falling off of the filling body during the solidification process. At the same time, the plug-in plate opening is provided on the card slot 2 to facilitate the filling of liquid A and liquid B into the gap between the card slot 2 and the tunnel. The plug-in plate opening is sealed by the plug-in plate to ensure that the filling body can be tightly filled in the gap between the card slot 2 and the tunnel, thereby improving the filling effect.

[0050] Furthermore, a pressure relief hole 5 is provided at the top of the tunnel, and the pressure relief hole 5 is connected to the gap, wherein the pressure relief hole 5 is used to observe the state of the filling body. The provision of the pressure relief hole 5 enables construction personnel to observe the solidification state and pressure changes of the filling body in real time, so as to adjust the construction parameters and plans in time. In addition, the pressure relief hole 5 can also be used as a pressure relief channel in an emergency to ensure the safety of the filling process.

[0051] Furthermore, before filling, liquid A and liquid B are placed in the same liquid bag, and liquid A and liquid B are separated by a diaphragm valve. This design not only simplifies the filling process, but also improves the filling efficiency. During filling, just open the diaphragm valve, liquid A and liquid B will automatically mix and flow into the card slot 2, liquid A and liquid B mix, chemically react, and automatically fill the gap between the card slot 2 and the lane, and the card slot 2 and the lane squeeze out excess material and bulge upward until the gap is filled.

[0052] Furthermore, the skeleton 1 is an alloy skeleton 1. The alloy skeleton 1 has excellent properties such as high strength, corrosion resistance, and high temperature resistance, and can meet the complex geological conditions and long-term load effects in the tunnel. In addition, the alloy skeleton 1 also has good plasticity and machinability, and is easy to customize and process according to the shape and size of the tunnel.

[0053] Furthermore, in step S3, liquid A and liquid B are filled into the gap through the plug-in port, including the following steps: first, liquid A and liquid B are poured into the plug-in port at the bottom of the tunnel wall, and then liquid A and liquid B are poured into the plug-in ports of each slot in order from bottom to top, until the filling body overflows from the pressure relief hole 5. During the filling process, the solidification state and pressure change of the filling body are continuously observed to ensure the filling effect and safety. At the same time, it is also necessary to pay attention to controlling the filling speed and filling amount to avoid filling too fast to cause loose filling or filling too slowly to cause waste.

[0054] Furthermore, the skeleton 1 is disassembled and recycled, including the following steps: first, the support rod 4 is disassembled, then the slot 2 abutting against the tunnel wall is disassembled, then the lead screw 3 is rotated, the lead screw 3 is disassembled, and finally the skeleton 1 is recycled. During the disassembly process, it is necessary to protect the integrity of the tunnel wall and the filling body to avoid damage or affect subsequent use. At the same time, the disassembled skeleton 1 needs to be inspected for reuse or repair.

[0055] In summary, in practical applications, this method has significant advantages and effects. First, the method adopts a hydraulic system with high support force, which can significantly improve the stability and safety of the tunnel, prevent leakage of the filling body, and reduce economic costs. Secondly, the method can be constructed quickly with a short construction time, can be quickly filled and quickly transferred, reduce construction costs and time, and improve construction efficiency and quality. Finally, the method is also environmentally friendly and sustainable. By transferring the recycled skeleton and other components to the next mining site using transportation equipment, the skeleton 1 is erected according to the mining site conditions, and the skeleton 1 is recycled to reduce economic expenditures.
