Abstract
Description
Technical Field
[0001] This utility model relates to the field of water-stop curtain technology, specifically to a water-stop curtain structure for mining areas. Background Technology
[0002] A mine cutoff wall is an important engineering measure specifically used for groundwater control and prevention in mining areas. With the continuous development of mining, the depth and scope of mine operations are gradually increasing, and the groundwater problems faced by mining areas are becoming increasingly complex. To effectively prevent groundwater from entering the mine or adversely affecting mining production, and to ensure the safety and efficiency of mining operations, it has become necessary to install continuous water-resistant structures around the mine pit or in specific areas. This water-resistant structure is the mine cutoff wall, and its main function is to physically block the path of groundwater flow, thereby reducing the impact of groundwater on mining activities.
[0003] Because mine cutoff walls need to block groundwater for extended periods, their construction requires high stability and strength. Due to the complex and variable underground environment of mining areas, coupled with long-term groundwater erosion, changes in ground pressure, and potential geological instability, mine cutoff walls may encounter a series of problems during use. For example, after a period of operation, the cutoff wall may develop faults or cracks, and in severe cases, even partial collapse may occur. These problems will directly affect the functionality of the cutoff wall, causing the previously blocked groundwater to find a new flow path, thus seriously impacting the progress and safety of mine construction. Utility Model Content
[0004] In view of the problems in the relevant technologies, this utility model proposes a water-stop curtain structure for mining areas to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] Therefore, the specific technical solution adopted by this utility model is as follows:
[0006] A water-stop curtain structure for mining areas includes a plurality of water-stop columns, which are interconnected to form a curtain wall. Positioning rods are installed on both sides of the interior of the curtain wall, and support frames are installed at both ends of the positioning rods. Reinforcing rods are connected between the frame frames inside the support frames. A repair grouting mechanism is provided between the support frame at the top of the positioning rod and the curtain wall.
[0007] Furthermore, in order to enable grouting repair when the curtain wall leaks, the repair grouting mechanism includes limiting rings connected to each side of the support frame surface, a conveying pipe installed inside the limiting ring, a number of grout discharge pipes connected to the surface of the conveying pipes, and a number of filling holes opened on the surface of the grout discharge pipes.
[0008] Furthermore, in order to achieve uniform repair of different areas on the outside of the curtain wall, the grout pipes are evenly distributed on each side surface of the delivery pipe, and the distance between each grout pipe and the waterstop column on both sides is the same.
[0009] Furthermore, in order to control the discharge of each slurry pipe, one end of the conveying pipe is connected to an injection pipe and the other end is connected to a cleaning pipe. Discharge valves are installed on the surface of both the cleaning pipe and the slurry pipe.
[0010] Furthermore, in order to achieve stable support for each side of the curtain wall through the reinforcing rods, the angle between the reinforcing rods and the frame of the support frame on both sides is 45 degrees.
[0011] Furthermore, in order to enable the free assembly and disassembly of the positioning rod and the support frame, the two sides of the positioning rod are fixedly connected to the curtain wall by bolts, and the support frame is fixedly connected to both ends of the positioning rod by bolts.
[0012] Furthermore, in order to monitor water seepage inside the curtain wall, hygrometers are fixedly installed on each side of the support frame at the bottom of the positioning rod.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By connecting the two ends of the positioning rod to the support frame and fixing it to the inner wall of the curtain wall, the curtain wall can be effectively stabilized and supported on all sides, preventing it from tilting and collapsing. The installation of the reinforcing rod inside the support frame can evenly distribute the pressure on the adjacent sides of the curtain wall when one side of the curtain wall has a tendency to tilt, so that the curtain wall supports each other and effectively enhances the stability of the curtain wall during use.
[0015] 2. By repairing the grouting mechanism, when water seepage occurs due to erosion cracks in the curtain wall, repair material can be injected into the delivery pipe, and the grout drain pipe of the corresponding seepage area can be opened to discharge the repair material, thereby achieving grouting repair, preventing further water seepage in the area, improving the waterproof effect of the curtain wall, effectively ensuring the curtain wall's ability to block groundwater, and achieving safe production in the mining area.

[0023] 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.
[0024] According to an embodiment of this utility model, a water-stop curtain structure for mining areas is provided.
[0025] like Figures 1-4 As shown, a mine water-stop curtain structure according to an embodiment of this utility model includes a plurality of water-stop columns 1, which are made of concrete. The water-stop columns 1 are interconnected to form a rectangular curtain wall 2. Two pairs of positioning rods 3 are installed on both sides of the interior of the curtain wall 2. Each positioning rod 3 has a support frame 4 installed at both ends to cooperate with the inner wall of the curtain wall 2. Reinforcing rods 5 are connected between the inner frames of the support frame 4. The angle between the reinforcing rods 5 and the frames of the two side support frames 4 is 45 degrees. The support frame 4 and the reinforcing rods 5 provide stable support for each side of the curtain wall 2 to prevent the curtain wall 2 from tilting or collapsing. A repair grouting mechanism 6 is provided between the support frame 4 at the top of the positioning rod 3 and the curtain wall 2 for grouting and repairing the seepage points on each side of the curtain wall 2, so as to continuously ensure the blocking effect of the curtain wall 2 on groundwater in the mine pit.
[0026] like Figures 1-4As shown, the repair grouting mechanism 6 includes limiting rings 601 connected to each side of the support frame 4. A conveying pipe 602 is installed inside the limiting rings 601 for conveying repair material. Multiple grout discharge pipes 603 are connected to the surface of the conveying pipe 602. Multiple filling holes 604 are opened on the surface of each grout discharge pipe 603. The grout discharge pipes are evenly distributed on each side of the conveying pipe 602, and the distance between each grout discharge pipe 603 and the two side waterstop columns 1 is the same. One end of the conveying pipe 602 is connected to an injection pipe 605 for injecting repair material into the conveying pipe 602, and the other end is connected to a cleaning pipe 606. After repair, the cleaning pipe 606 closes the discharge valves 607 on all grout discharge pipes 603 and cleans and discharges the conveying pipe 602 after filling it with water, preventing the repair material from solidifying in the conveying pipe 602. The cleaning pipe 606 is connected to the grout discharge pipe 604. All surfaces of the curtain wall 2 are equipped with discharge valves 607 to control the flow of repair material from the delivery pipe 602 into the grout discharge pipe 603. When a certain area of the curtain wall 2 is eroded and cracks appear, causing water seepage, repair materials such as concrete can be injected into the delivery pipe 602, and the grout discharge pipe 603 corresponding to the seepage area can be opened to discharge the repair material, thereby achieving grouting repair. The positioning rod 3 is fixedly connected to the curtain wall 2 on both sides by bolts, and the support frame 4 is fixedly connected to both ends of the positioning rod 3 by bolts, which is used to install and disassemble the positioning rod 3 and the support frame 4. Hygrometers 7 are fixedly installed on each side of the support frame 4 at the bottom of the positioning rod 3 to detect the humidity at the bottom of the inner wall of the curtain wall 2. The side of the bottom of the curtain wall 2 with higher humidity can be observed in detail, so as to promptly detect and repair the seepage area on the curtain wall 2.
[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0028] In practical use, the positioning rod 3 is connected to the support frame 4 at both ends and fixedly installed on the inner wall of the curtain wall 2. This effectively provides stable support for each side of the curtain wall 2, preventing it from tilting and collapsing. The installation of the reinforcing rod 5 inside the support frame 4 can evenly distribute the pressure on the adjacent sides of the curtain wall 2 when one side of the curtain wall 2 has a tendency to tilt, so that each side of the curtain wall 2 supports each other, effectively enhancing the stability of the curtain wall 2 during use. When a certain area of the curtain wall 2 is eroded and cracks appear, causing water seepage, repair materials such as concrete can be injected into the delivery pipe 602 through the injection pipe 605, and the discharge valve 607 on the corresponding seepage area drainage pipe 603 can be opened to discharge the repair material through the drainage pipe 603, thereby achieving grouting repair.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
