Description

Technical Field

[0001] The utility model relates to the field of tunnel engineering, and particularly to a fire pump house. Background Art

[0002] With the acceleration of the urbanization process, underground traffic tunnels have become an important part of modern urban transportation. In dealing with emergencies such as sudden fires, the fire safety design in tunnels is crucial. The tunnel space is relatively enclosed and the ventilation conditions are poor. Once a fire breaks out, the fire is likely to spread rapidly, threatening the safety of personnel and the integrity of the tunnel structure. Therefore, how to effectively arrange fire-fighting facilities, especially fire pump houses, in the tunnel environment has become a difficult problem to be solved urgently in the field of tunnel engineering.

[0003] At present, most of the fire-fighting systems in tunnels adopt the traditional layout methods of fire-fighting pipes and sprinklers. However, many defects have been exposed in this design in practical applications. On the one hand, due to the long length of the tunnel, the water pressure transmission distance of the existing fire-fighting system is too long, resulting in insufficient water pressure and making it difficult to guarantee the fire extinguishing effect in the remote areas. On the other hand, the existing fire-fighting pipe layout is relatively complex, occupying the limited space in the tunnel and affecting the layout and maintenance of other infrastructure. In addition, the maintenance work of the traditional fire-fighting system is complex, especially in the narrow tunnel environment, and it is difficult to operate the equipment for inspection and maintenance.

[0004] Therefore, there is an urgent need for a new structure that can reasonably arrange the fire pump house in the tunnel inclined shaft to improve the water pressure transmission efficiency, optimize the space utilization, simplify the maintenance work, and improve the overall fire safety in the tunnel.

[0028] An embodiment of the present utility model provides a fire pump house disposed in the inclined shaft 2 of the tunnel 1, including: a pump house bottom plate 3-2-4, surrounding side walls 3-2-3, a pump house top plate 3-2-5, and a middle partition wall 3-2-2; the middle partition wall 3-2-2 divides the fire pump house into an equipment room 3-1 and a water storage tank 3-2, wherein the equipment room 3-1 is used to accommodate fire pumps, fire water tanks, control cabinets, and valves, and the water storage tank 3-2 is used to accommodate fire water.

[0029] In the related art, tunnel fire protection adopts the method of installing fire pipelines and sprinkler heads on the side walls or tops of tunnels, which is difficult to meet the tunnel fire protection requirements. In the embodiment of the present utility model, a fire pump house is arranged in the inclined shaft 2 of the tunnel 1, which can save space utilization and reduce the response time on the basis of meeting the tunnel fire protection requirements.

[0030] According to the embodiments of the present utility model, the pump house floor 3-2-4, the pump house roof 3-2-5, and the middle partition wall 3-2-2 are all of reinforced concrete structure, and the surrounding side walls 3-2-3 are composed of primary support and secondary lining.

[0031] In the related art, in a tunnel environment, the pump house bears relatively large pressure and stress, and traditional materials are prone to damage or aging. In the embodiments of the present utility model, the pump house floor, roof, and middle partition wall all adopt reinforced concrete structures, enhancing the overall strength and durability. The surrounding side walls are composed of primary support and secondary lining, further improving the structural stability and compressive capacity of the pump house, ensuring its long-term reliable operation in the complex tunnel environment.

[0032] According to the embodiments of the present utility model, the equipment room 3-1 further includes a staircase 3-1-1 and surrounding guardrails 3-1-2, wherein the height of the guardrails is not less than 1.2 meters.

[0033] According to the embodiments of the present utility model, the water storage tank 3-2 is provided with a plurality of inspection holes, and the inspection holes are provided with steel straight ladders and steel covers, and the diameter of the inspection holes is not less than 1 meter.

[0034] According to the embodiments of the present utility model, the inner surfaces of the equipment room 3-1 and the water storage tank 3-2 are coated with a 2-mm-thick cementitious capillary crystalline waterproof coating.

[0035] According to the embodiments of the present utility model, the fire pump house further includes a connecting pipe for connecting the fire protection system in the tunnel 1, and the connecting pipe is made of stainless steel.

[0039] According to the embodiments of the present utility model, the inclination angle of the inclined shaft 2 is 5° to 10°.

[0040] In the related art, the design of the inclination angle of the tunnel inclined shaft lacks a unified standard, resulting in poor water flow or unreasonable pump house layout, affecting the overall efficiency of the fire protection system. In the embodiments of the present utility model, the inclination angle of the inclined shaft is set to 5° to 10°, which not only ensures that the fire protection water source can smoothly flow into the water storage tank but also facilitates maintenance personnel to enter the inclined shaft for maintenance work conveniently.

[0041] The method of the present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0042] The core of the present utility model lies in providing a structural type with a fire pump room arranged in an inclined shaft.

[0043] Inclined shaft 2: In order to ensure the construction period of the main tunnel, setting an inclined shaft to increase the construction working face of the main tunnel is the most effective means in tunnel construction. The inclined shaft is only used as an auxiliary construction passage during the construction period and generally loses its use function during the operation period and is abandoned, resulting in a great waste of the project. The present utility model uses the inclined shaft 2 as the passage for arranging the fire pump room 3 and connecting the fire pump room with the fire protection system in the tunnel. The inclination angle of the inclined shaft is preferably between 5° and 10°, which can not only ensure the stability of the pump installation but also facilitate maintenance personnel to enter the inclined shaft for maintenance work conveniently.

[0045] Figure 6 As shown in the cross-section drawing of the storage pool according to the embodiment of the present utility model, such as Figure 6As shown in the figure, the main structure of the water storage tank consists of a middle partition wall 3-2-2, side walls 3-2-3, a bottom plate 3-2-4 and a top plate 3-2-5; the side walls are composed of primary support (sprayed concrete + wire mesh, etc.) and secondary lining (reinforced concrete), and the middle partition wall, bottom plate and top plate are all reinforced concrete structures; the water storage tank needs to be provided with inspection holes, the size of the inspection holes is not less than 1m, and there shall be no less than 2 places. A steel straight ladder and a steel cover plate shall be provided at the inspection holes.

[0046] Figure 7 It is a cross-sectional view of the equipment room according to an embodiment of the present invention. As Figure 7 shown, the main structure of the equipment room consists of a middle partition wall 3-2-2, side walls 3-2-3 and a bottom plate 3-2-4; in addition to its own main structure and related equipment, the equipment room also includes a staircase 3-1-1 and a guardrail 3-1-2.
