[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0025] Fire safety is of paramount importance during the excavation and secondary lining construction of urban subway tunnels and underground stations. Especially during secondary lining construction, the increased workload related to waterproofing materials, timber, hot work, and electrical work creates new risks of fire.

[0026] Traditional tunnel fire prevention measures largely rely on temporary fire extinguishers to effectively control and extinguish initial fires. However, traditional fire extinguishers are frequently moved during tunnel excavation, making them prone to damage and unable to adequately address fire prevention issues in mined tunnels.

[0027] To resolve the above technical issues, please refer to Figures 1 to 2This application provides a tunnel fire-fighting operation system 100, which may include a water storage tank 110, a water supply pipeline 120, a first valve 130, a second valve, a first fire hydrant 140, and a second fire hydrant.

[0028] Specifically, the water storage tank 110 defines a water storage cavity, and the water storage tank 110 is connected to the tunnel's water supply system. The tunnel's water supply system fills the water storage cavity with water. It should be noted that during the tunnel construction process, in order to meet the water requirements inside the tunnel, a tunnel water storage tank will be built on the ground in advance. The water storage tank 110 can directly adopt the tunnel water storage tank.

[0029] The water supply pipeline 120 may include a first port and a second port, the first port being connected to the water storage chamber, and the second port being either sealed or left open. The water supply pipeline 120 is typically made of steel pipe with a 100mm diameter bore.

[0030] The first valve 130 and the second valve are connected in series on the water supply pipeline 120. The second valve is located between the first valve 130 and the second port. Both the first valve 130 and the second valve can regulate the water flow rate through them.

[0031] The first fire hydrant 140 and the second fire hydrant are connected in series on the water supply pipeline 120. The first fire hydrant 140 is located between the first valve 130 and the first port, and the second fire hydrant is located between the first valve 130 and the second valve.

[0032] It should be noted that, in this way, when a fire occurs in the tunnel area near the first fire hydrant 140, the operator can adjust the first valve 130 to the closed state, thereby cutting off the water flow and ensuring the water pressure at the first fire hydrant 140. The operator can then connect the fire pipeline to the first fire hydrant 140 to carry out water spraying and fire extinguishing operations, which can ensure the timely control of the fire.

[0033] When a fire occurs in the tunnel area where the second fire hydrant is located, the operator can adjust the first valve 130 to the open position, and adjust the first fire hydrant 140 and the second valve to the closed position to ensure water pressure at the second fire hydrant. The operator can then connect the fire pipeline to the second fire hydrant to carry out water spraying and fire extinguishing operations, ensuring timely control of the fire.

[0034] This can be understood as meaning that when the tunnel fire protection system 100 is not in operation, both the first valve 130 and the second valve can be in the closed state.

[0035] In some embodiments of this application, in order to better ensure the water pressure during the water spraying fire extinguishing operation, a booster pump 150 can be installed between the first fire hydrant 140 and the first port.

[0036] In some embodiments of this application, the tunnel fire protection system 100 may further include a third valve and a third fire hydrant, which are connected in series on the water supply pipeline 120. The third valve is located between the second port and the second valve, and the third fire hydrant is located between the second valve and the third valve.

[0037] Therefore, by setting up the first valve 130 and the first fire hydrant 140, the second valve and the second fire hydrant, and the third valve and the third fire hydrant, the tunnel can be divided into three areas with the same length of water supply pipeline 120. Firefighting operations can be carried out through three fire hydrants respectively, making firefighting operations more precise and the firefighting response more rapid. Fires can be extinguished in the initial stage, which is more conducive to controlling the spread of fire inside the tunnel.

[0038] In the specific implementation process, the tunnel fire protection system 100 may also include a fourth valve and a fourth fire hydrant, a fifth valve and a fifth fire hydrant, a sixth valve and a sixth fire hydrant, etc.

[0039] Furthermore, the distance between the first port and the first valve 130 is the first distance, and the distance between the first valve 130 and the second valve is the second distance. The first distance is equal to the second distance.

[0040] In this way, the tunnel area corresponding to the first fire hydrant 140 and the tunnel area corresponding to the second fire hydrant are of the same length, and the areas radiated by the first fire hydrant 140 and the second fire hydrant are the same. When a fire occurs inside the tunnel, the operator can select the nearest fire hydrant to carry out firefighting operations more quickly and in a timely manner.

[0041] In some embodiments of this application, the first valve 130 includes a valve body 131, a first connecting pipe 132, and a second connecting pipe 133. The valve body 131 includes a first connecting port and a second connecting port. The first connecting pipe 132 includes a third port and a fourth port, and the third port is detachably and sealingly connected to the first connecting port. The second connecting pipe 133 includes a fifth port and a sixth port, and the fifth port is detachably and sealingly connected to the second connecting port. The first valve 130 is connected in series to the water supply pipeline 120 through the fourth port and the sixth port.

[0042] Among them, the first valve 130 can be a gate valve, and the second, third and fourth valves can all be gate valves.

[0043] In this way, by setting the first connecting pipe 132 and the second connecting pipe 133, the original water supply pipeline 120 can be simply cut open and reused by connecting the first valve 130 in series in the water supply pipeline 120.

[0044] Both the first connecting pipe 132 and the second connecting pipe 133 can be made of steel pipe with a diameter of 100mm.

[0045] Specifically, the first port and the first connection port are connected by a thread. In the specific implementation process, the first port is provided with an external thread, and the first connection port is provided with an external thread.

[0046] A sealing ring may also be fitted between the first port and the first connection port.

[0047] Furthermore, the fourth port has the same diameter as the water supply pipe 120, and can be connected by welding.

[0048] In some embodiments of this application, the tunnel fire-fighting system 100 may further include a third connecting pipe 160, which may include a seventh port and an eighth port. The seventh port is connected to the water supply pipe 120, and the eighth port is connected to the first fire hydrant 140.

[0049] Therefore, by setting up a third connecting pipe 160, the connection between the first fire hydrant 140 and the water supply pipe 120 is achieved.

[0050] Furthermore, the eighth port is connected to the first fire hydrant 140 by a thread, and a sealing ring may be clamped between the eighth port and the first fire hydrant 140.
