Description

Technical Field

[0001] The invention relates to a mine water hazard rapid treatment technology, and in particular to a gall-containing rapid self-built sluice wall system and an installation method and application thereof. Background Art

[0002] The hydrogeological conditions of mines in my country are complex, and mine water inrush disasters occur frequently, such as water seepage from old empty space, water inrush from collapsed columns, water inrush from faults, and water intrusion from loose layers. Since there is no effective prevention method, these disasters often cause the death of underground workers or flooding of mines. For example, in early 2015, a water inrush from a hidden collapsed column on the bottom of the coal seam occurred at Fengfeng Wutongzhuang Coal Mine, with water flowing from 80m 3 / h, increased to 25000m after 36h 3 / h, causing the well to be flooded. There were also collapse columns that caused 32 deaths in Luotuoshan Coal Mine, 17 deaths in Fangezhuang Coal Mine, and flooding in five coal mines, including Xingtai Dongpang Coal Mine. The flooding time was between 3 and 30 hours. Heavy rain or flood inflow or infiltration often causes excessive water volume in the well, leading to disasters. For example, 186 deaths in Huayu Coal Mine and 4 deaths in Leping Yangou Coal Mine were caused by floods. Every year, coal mines in South China, North China, Northeast China, and Northwest my country suffer from heavy rain or flood disasters. Traditional concrete sluice wall water blocking cannot achieve the purpose of rapid water blocking because the construction speed is too slow to be built and shaped in time. Therefore, there is an urgent need for equipment and technology that can quickly block water to prevent the occurrence of such water disasters.

[0003] Sluice walls are a mature flood control technology in my country, but they are all artificially built after the disaster. The entire sluice wall construction project takes more than 96 hours, plus the 72 hours required for concrete solidification, the total time is 7 days and nights. In recent years, due to the application of chemical slurry, the sluice wall can be completed in 48 hours. However, when the water volume is large and the water volume continues to increase, the sluice wall is often not yet formed and the mine has been flooded. This kind of artificial sluice wall project can only be constructed after the water volume stabilizes, which can only be post-disaster isolation and cannot play a role in disaster prevention and relief. In order to solve this problem, some scholars in my country have invented the technology of rapid self-built sluice wall, but it uses a single-layer non-bladder bag body, which consumes a lot of materials and takes a long time to build, and cannot completely control underground water hazards. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a rapid self-built sluice wall system containing gallbladder in view of the deficiencies of the above-mentioned prior art. The system can realize the rapid and automatic formation of a high-strength sluice wall, effectively prevent the occurrence of water disasters, and provide protection for the life and property safety of personnel in mines.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a rapid self-built sluice wall system containing a bladder, characterized in that it includes a bag system, a filling system, a fixing system and an automatic control system.

[0006] The bag system consists of a high-strength textile outer bag, an expandable high-temperature resistant inner liner, a spraying pipe and a water injection pipe. The inner liner is arranged in the outer bag and a cavity interlayer is formed between the inner liner and the outer bag. The spraying pipe passes through the outer bag and is connected to the cavity interlayer, and the water injection pipe passes through the outer bag and is connected to the inner liner. The outer bag is a single-layer structure outer bag or a double-layer structure outer bag, and the outer bag is made of high-strength textile.

[0007] When the bag system is filled with the expanded and solidified organic-inorganic hybrid material and water, the solidified material and water will be in a static state, the expanded and solidified filling material will shrink due to cooling, and the initially formed sluice wall will leak. For the single-layer outer bag body, high-pressure water injection into the inner liner will continue at this time to cause the bag system to expand secondary to maintain the water blocking effect. On the other hand, for the double-layer outer bag body, the cavity interlayer in the bag system will continue to be grouting and filled to maintain the water blocking effect.

[0008] The filling system includes a primary filling system and a secondary filling system. The primary filling system includes a large filling storage tank, a first grouting pipeline and a water filling pipeline. The inlet of the large filling storage tank is connected to the air outlet of the existing high-pressure air duct underground, and the outlet of the large filling storage tank is connected to the grouting pipe through the first grouting pipeline. One end of the water filling pipeline is connected to the existing high-pressure water pipe underground, and the other end of the water filling pipeline is connected to the water injection pipe. A pressure pump is installed on the water filling pipeline, and a liquid mixer is installed on the first grouting pipeline. The secondary filling system includes a small filling storage tank and a second grouting pipeline. The filling The inlet of the small storage tank is connected with the outlet of the existing high-pressure air duct underground, and the outlet is connected to the cavity interlayer of the bag system through the second grouting pipeline. The second grouting pipeline is successively installed with a pressure pump and a liquid mixer. The large filling storage tank and the small filling storage tank both store two liquid materials A and B at the same time, that is, a large storage tank for material A, a large storage tank for material B, a small storage tank for material A and a small storage tank for material B. The A and B materials are mixed to become expanded and solidified fillers. Three-way automatic gate valves are installed at the outlets of the high-pressure air duct and the high-pressure water pipe; the secondary filling system is installed on the bag system of the double-layer outer bag.

[0009] Both the primary filling system and the secondary filling system utilize the existing high-pressure air duct as power to fill the mixed liquid material into the bag system through two material tanks placed on one side of the tunnel. The gas in the high-pressure air duct applies pressure on the top surface of the filling storage tank, driving the liquid to flow to the inlet at the bottom of the riser in the tank and enter the liquid mixer for mixing.

[0010] The fixing system includes an existing anchor rod or anchor cable located on the top plate of the tunnel underground, a pulling rope, a blocking column and a retractable belt rack installed at the rear of the bag body. The bag body system is connected to the anchor rod or anchor cable via a fixed joint directly above, and the front end of the bag body system is connected to the anchor rod or anchor cable via a pulling rope. The blocking column is vertically arranged at the rear end of the bag body system. The function of the pulling rope is to prevent the bag body system from shaking its head and getting entangled when water bursts into the tunnel. The function of the blocking column is to prevent the bag body system from swinging its tail and getting entangled when water bursts into the tunnel. The blocking column can be a hydraulic support or a high-angle blocking frame.

[0011] The automatic control system is an existing automatic control substation, which is installed on the side wall of the rear lane of the bag system. The automatic control system is connected to the retractable belt rack and the automatic gate valve, and can release the bag system by controlling the extension and retraction of the retractable belt rack, and control the opening and closing of the high-pressure air duct and the high-pressure water pipe by controlling each automatic gate valve.

[0012] The gallbladder-containing rapid self-built sluice wall system also includes a diversion system and a water pressure sensor arranged in the drainage groove of the bottom plate of the laneway behind the bag system. The diversion system includes a diversion water pipe fixed by concrete and half lying in the bottom plate and an automatic gate valve installed at the outlet of the diversion water pipe. The diversion water pipe made of metal water pipe is used to replace the drainage ditch of the bottom plate to discharge the surrounding rock water in the excavation process, avoid the sluice wall to block the drainage ditch tightly, or the malignant water inrush during the construction of the diversion sluice wall, and reduce the swing of the sluice wall. The diversion water pipe is built into an arc with concrete to avoid the problem of loose blocking caused by the intersection of the pipe and the bottom plate at a sharp angle. The diameter of the diversion water pipe is based on the principle of not affecting the extension and contraction of the belt frame, and the length of the diversion water pipe is preferably longer than the sluice wall by more than 0.5m. The water pressure sensor and the automatic gate valve on the diversion water pipe are both connected to the automatic control system.

[0013] Preferably, the outer bag is the main body of the sluice wall, which is the main body that constrains the shape of the sluice wall and blocks the water flow. The cross-sectional size of the outer bag is greater than 1.2 times the cross-sectional size of the tunnel.

[0014] Preferably, the inner liner is suspended in the outer bag by a connecting rope.

[0015] Preferably, the two ends of the outer bag can be fixed by sewing, gluing or tying, wherein when the tying method is used, it is fixed by a tying ring, and the tying ring is provided with a metal ring for pulling and fixing with an external rope.

[0016] Preferably, the liquid mixer is an impeller installed at both ends of a section of grouting pipeline.

[0017] Preferably, the two liquid materials A and B are non-toxic, odorless and non-corrosive. The expansion multiple of the two liquid materials A and B after mixing is about 10, and the initial expansion time is controllable from 15s to 300s, the expansion duration is less than 20s, and the compressive strength of the mixed material after expansion and curing is greater than 5MPa.

[0018] A method for installing a rapid self-built sluice wall system in a mine tunnel comprises the following steps:

[0019] Step 801, select a tunnel behind the transfer machine, and install the bag body on the top plate of the tunnel in the folding form required by the bag body system manual;

[0020] Step 802, installing a diversion system at the tunnel floor position corresponding to the bag system;

[0021] Step 803: Determine the length of the pulling rope according to the calculation method given in the manual, and fix the pulling rope to the hook of the anchor rod or anchor cable on the top plate in front of the bag body;

[0022] Step 804: Install the three-way automatic gate valve at the ends of the high-pressure air pipe and the high-pressure water pipe at the rear of the bag system;

[0024] Step 806, installing the automatic control system on the side wall of the lane behind the bag system;

[0025] Step 807, install the water pressure sensor in a special container at the drainage groove of the bottom plate at the rear of the bag body, and connect it to the automatic control system;

[0026] Step 808, install the filling material storage tank behind the bag system against the tunnel wall;

[0027] Step 809, sequentially connect the high-pressure air duct, the filling material storage tank, the first grouting pipeline and the spraying pipe, and sequentially connect the high-pressure water pipe, the water filling pipeline and the water injection pipe, wherein a liquid mixer is installed on the first grouting pipeline, and a pressure pump is installed on the water filling pipeline;

[0028] Step 810, connect the high-pressure air duct, the filling material storage tank, and the second grouting pipeline in sequence to the bag system in which the outer bag is a double-layer bag and the inner liner bag, and install a booster pump and a liquid mixer on the second grouting pipeline.

[0029] The order of the above steps 801-810 is not fixed and can be performed simultaneously. The arrangement height of the special container equipped with the water pressure sensor and the activation threshold of the sluice wall should be determined according to the hydrogeological conditions of the mine. The large and small material storage tanks are fixed on the tunnel floor or tunnel wall to prevent them from being knocked down by sudden water and losing their function. The large and small material storage tanks can be connected or separated.

[0030] The length of the pulling rope should be adjustable as needed, and the adjusted length should remain fixed. The tensile strength of the pulling rope should not be less than 20T. The tunnel for building the sluice wall should have good engineering geological conditions: good surrounding rock integrity, no cracks, no spalling or roof collapse, and no delamination of the roof. If the surrounding rock does not meet the above requirements, the surrounding rock should be treated with chemical grouting, and the sluice wall can be built only after it meets the standards.

[0031] A fast self-built sluice wall system containing gallbladder is applied to underground water blocking in a mine, and the water blocking method comprises the following steps:

[0032] Step 901: When a water disaster occurs, the water pressure sensor sends a signal to the automatic control system;

[0033] Step 902, the automatic control system controls the retractable belt frame to retract, so that the bag system automatically falls from the tunnel roof and unfolds;

[0034] Step 903: Open the valves of the high-pressure air pipe and the high-pressure water pipe;

[0035] Step 904: Liquids A and B in the filling material storage tank are mixed by a liquid mixer and then injected into the cavity interlayer in the bag system;

[0036] Step 905, the mixed liquid injected into the bag system expands and solidifies;

[0037] Step 906: The water in the high-pressure water pipe is injected into the inner tank through the water filling pipeline;

[0038] Step 907: the outer bag is filled and the pressurized filling system stops working, and the water in the lane is temporarily blocked;

[0039] Step 908, the automatic gate valve of the diversion system is closed;

[0040] Step 909, the bag system cools and shrinks, causing secondary water leakage in the tunnel;

[0041] Step 910: For the double-layer bag inner liner, the high-pressure air duct valve connected to the secondary filling system is opened, and the secondary filling system is operated to perform secondary grouting filling on the double-layer outer bag; for the single-layer outer bag, the pressure pump on the water filling pipeline is started to inject water into the inner liner for the second time;

[0042] Step 911, when the secondary grouting and secondary water filling of the bag system are completed, the water damage stops and the bag system completely blocks the tunnel.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] 1. The sluice wall in the present invention is self-built, and the filling materials are slurry and water, which is twice as fast as the earlier similar patented technology. Moreover, the filling materials are all located on site, eliminating the transportation time. The filling speed is the maximum flow of the high-pressure gas or water pipeline, and the filling time is less than 20 minutes. The construction speed is about 144 times faster than the traditional concrete sluice wall and 24 times faster than the sluice wall cast by chemical slurry, which can greatly reduce the risk of well flooding.

[0045] 2. The sluice wall constructed by the present invention has high strength and high water pressure resistance. The tensile strength of the sluice wall bag system is greater than 10MPa. Under the limit of 10 times expansion multiple, the ability of the filler to resist water pressure after expansion, solidification and hardening is greater than 3MPa. The bag strength is greater than the expansion pressure of the filler, and the bag will not burst, which is safe and reliable.

[0046] 3. The bag system of the present invention has strong rupture resistance, which can effectively avoid the hidden danger of leakage caused by the traditional bag system being easily punctured by sharp rocks protruding from the tunnel wall, broken metal mesh, and pointed ends of anchor rods or anchor cables after being subjected to the expansion pressure of the filler.

[0047] 4. The pipelines in the present invention are all connected by quick connectors on the three-way valve, and the system adopts a programmed construction plan. The pulling rope and the textile bag, the filling storage tank and the anchor head are all connected by a locked hook, so the construction is convenient and easy. The water gate wall determines whether a water disaster occurs through the water pressure data collected by the water pressure sensor, and can respond in time, which can provide good protection for the safety of life and property underground.

[0048] 5. The present invention designs a double-layer inner bag body and a single-layer inner bag body as the main body of the sluice wall, which can be filled with expansion curing materials and water at the same time. When a secondary leakage occurs after the initial filling of the sluice wall, a secondary filling is performed, eliminating the problem of cooling and shrinking leakage of the filler and continuously maintaining the sealing effect.

[0069] like Figure 1 As shown, the present invention includes a bag system, a filling system, a fixing system and an automatic control system.

[0070] like Figures 2 to 5 As shown, the bag system is composed of a high-strength textile outer bag 11, an expandable high-temperature resistant rubber inner bag 22, a spraying pipe 44 and a water injection pipe 3. The inner bag 2 is arranged in the outer bag 1 and a cavity interlayer is formed between the inner bag 2 and the outer bag 1. The spraying pipe 4 passes through the outer bag 1 to communicate with the cavity interlayer, and the water injection pipe passes through the outer bag 1 to communicate with the inner bag 2; the outer bag 1 is a single-layer structure outer bag or a double-layer structure outer bag, and the single-layer structure outer bag; the outer bag 1 is made of high-strength textile.

[0071] When the bag system is filled with the expanded and solidified organic-inorganic hybrid material and water, the solidified material and water will be in a static state, the expanded and solidified filling material will shrink due to cooling, and the initially formed sluice wall will leak. For the single-layer outer bag body, high-pressure water injection into the inner liner 2 is continued at this time to cause the bag system to expand secondary to maintain the water blocking effect. On the other hand, for the double-layer outer bag body, the cavity interlayer in the bag system is continued to be grouting filled to maintain the water blocking effect.

[0072] like Figure 6 As shown, the filling system includes a primary filling system and a secondary filling system. The primary filling system includes a large filling storage tank, a first grouting pipeline 11 and a water filling pipeline 15.

A pressure pump is installed on the water filling pipeline 15, and a liquid mixer is installed on the first grouting pipeline 11; the secondary filling system includes a small filling storage tank and a second grouting pipeline 12, the The inlet of the small filling storage tank is connected with the outlet of the existing high-pressure air duct 9 underground, and the outlet is connected to the cavity interlayer of the bag system through the second grouting pipeline 12. The second grouting pipeline 12 is successively installed with a pressure pump and a liquid mixer. The large filling storage tank and the small filling storage tank both store two liquid materials A and B at the same time, namely, the large A material storage tank 5, the B material storage tank 7, the A material storage tank 6 and the B material storage tank 8.

The diversion system includes a diversion water pipe fixed by concrete and half lying in the bottom plate 22 and an automatic gate valve 21 installed at the outlet of the diversion water pipe. The diversion water pipe made of metal water pipe is used to replace the drainage ditch of the bottom plate 22 to discharge the surrounding rock water in the excavation process, avoid the sluice wall to block the drainage ditch tightly, or the malignant water inrush during the construction of the diversion sluice wall, and reduce the swing of the sluice wall. The diversion water pipe is built into an arc with concrete to avoid the problem of poor blocking caused by the intersection of the pipe and the bottom plate 22 at an acute angle. The diameter of the diversion water pipe is based on the principle of not affecting the extension and contraction of the belt frame, and the length of the diversion water pipe is preferably longer than the sluice wall by more than 0.5m.
