Description
Technical Field
The invention belongs to the technical field of highway tunnel fire fighting, and particularly relates to a dry-type water fire fighting control system of a tunnel subarea relay water supply pipeline.
Background
China has drawn attention in the construction fields of highway tunnels, urban road underground passages and the like, and has become the world with the most tunnel and underground engineering, the most complex and the fastest development speed. Road tunnels have been moved from heavy dunes to deep mountains, from land to underwater, and from suburbs into cities. The tunnel is also longer and wider, the line shape and the structural style of the tunnel are more colorful, and the forms of the spiral tunnel, the small clear distance tunnel, the multiple arch tunnel, the bifurcation tunnel and the like are derived. The systems for ventilation, lighting, monitoring, power supply and distribution, fire fighting, escape and rescue, etc. required by the operation of the facilities in the tunnel are increasingly complex. Meanwhile, as the driving in the tunnel is influenced by complex factors such as space, light environment, sight line, abnormal psychology and behavior of drivers and the like, various traffic accidents are easily induced; at present, the production and transportation management of dangerous chemicals in China does not completely reach the source-related radical treatment, and certain loopholes exist in the production and inspection of special vehicles. All the problems are that the spontaneous combustion of the automobile engine in the tunnel, the ignition of tires, the ignition of accident collision, the leakage, combustion and explosion of goods, particularly dangerous chemicals, the fire caused by electric line faults and other reasons are more and more, and the prevention is not sufficient. The tunnel is a special tubular structure, is fundamentally different from a common open road section, has the characteristics of closure, complexity, difficulty in connection and rescue and the like, and belongs to a special road section. The tunnel fire disaster has unpredictability, diversity and uncertainty of height, the tunnel can be used as a closed space, the temperature can be rapidly increased to more than 1000 ℃ within 2-10 minutes after the fire disaster occurs, the fiery airflow is spread rapidly along the wind, vehicles in the tunnel are difficult to evacuate, and therefore more vehicles are ignited due to the development of the fire along the traffic flow. Once a fire disaster happens in the tunnel, the damage is extremely large, and the life and property safety of people and the tunnel structure in the tunnel are greatly damaged.
In the existing fire-fighting equipment in tunnels in China, the medium and short tunnels are mainly 'fire extinguishers', and the single hole and the most of the long tunnels are 'fire extinguishers + foam fire hydrant systems + fire hydrant systems'. After long-term use, the effect of the fire hydrant fire extinguishing system is widely accepted and highly evaluated, and the fire hydrant fire extinguishing system plays a prominent role as an important component of tunnel fire safety and life safety systems. The fire hydrant fire extinguishing system has the fire extinguishing function and the cooling function at first, can extinguish fire in a hole and cool a high-temperature environment, thereby striving for more time for people evacuation in the hole and being beneficial to more effective rescue operation. Meanwhile, the fire hydrant fire extinguishing system can reduce the spread of fire to other vehicles to the maximum extent, inhibit the development of fire, guarantee personnel and property and reduce the loss caused by the fire.
Since the mountainous area usually has no municipal water supply system or tap water supply, the traditional tunnel water fire-fighting system in the mountainous area is generally divided into an ordinary high pressure fire-fighting system and a stable high pressure fire-fighting system, wherein the ordinary high pressure fire-fighting system comprises a water source self-contained well, a mountain constant flow water source or water supplemented by a waterwheel, a low-level pool, a high-pressure pipeline system, a fire hydrant box, a water tap and a water gun. Although the high-pressure stabilizing fire-fighting system is not provided with a high-level water tank, an air pressure pressurizing system and a fire-fighting water pump are additionally arranged for pressurizing. At present, the traditional tunnel water fire-fighting system has the following problems:
1. the pipeline of the traditional water fire-fighting system is in a continuous high-pressure state. For a tunnel with the length of 1000 meters, the maximum pressure in the pipeline is about 0.7 MPa; the tunnel is about 3000 meters long, and the maximum pressure in the pipeline is about 1-1.5 MPa; the length of the tunnel is 5000 meters, and the maximum pressure in the pipeline reaches 1.3-1.8 MPa; in a tunnel with a length of more than 10000 meters, the maximum pressure in the pipeline will exceed 2.0 MPa. The long-term continuous high-pressure state requires that the material of the pipeline must reach a higher level, otherwise pipe explosion or at least the service life of the pipeline is greatly shortened, and the damage of a pipeline valve and a pipe joint is greatly increased. In addition, the water source in the mountain area is rarely treated, and the pipeline is seriously corroded due to poor water quality, so that the service life of the pipeline is further shortened.
2. For northern seasonal freezing areas, an electric tracing heat insulation system must be arranged, and a pool and pipelines must be completely wrapped by heat insulation materials. In winter, the power supply is turned on for one month if the heat tracing is less, the power supply is turned on for 4 to 5 months if the heat tracing is more, and the power consumption is very large; after the heat-insulating layer is used for a long time, the heat-insulating layer is aged and cracked, and the heat-insulating effect is reduced along with the increase of the time. When the pipeline leaks for various reasons, the pipeline is completely wrapped by the heat-insulating layer and is not easy to find, and at present, no good means is provided for accurately checking and positioning the leakage point of the pipeline or mainly using destructive test inspection, so that the time and labor are wasted, and the efficiency is low.
3. Wasting water resources. The phenomena of pipeline leakage, pipeline burst, pipe joint disconnection, valve damage and the like of the traditional tunnel water fire-fighting system occur occasionally, water supplementing operation needs to be carried out frequently, and extreme conditions that water needs to be supplemented by at least 40 cubic meters every day appear in individual tunnels according to investigation.
4. The intensity of fire extinguishing system maintenance management is big. The pipeline which is in a continuous high-pressure state for a long time is very easy to leak and explode, and the inspection and maintenance work needs to be strengthened so as to ensure the stable operation of the fire-fighting system. In addition, the heat insulation system of the pipeline in the northern seasonal freezing area not only has high power consumption, but also needs to be periodically replaced to ensure the heat insulation effect, and also brings great workload for the maintenance of the fire protection system.

By adopting the system, the communication pipeline and the monitoring and control system between the high-level water pool and the related high-level water pool and the low-level water pool can be cancelled, so that the land occupation is reduced, and the damage to the vegetation is also reduced.
5. The invention can reduce the maintenance workload. The invention cancels the communication pipeline and the monitoring and controlling system between the high-level water tank and the related high-level water tank of the traditional tunnel water fire-fighting system, and thermal insulation measures such as thermal insulation layer, electric heat tracing and the like are not needed in the northern freezing area, the influence of corrosion on the pipeline is reduced without water level in the pipeline, the service life of the pipeline is prolonged, and the damage of the pipeline valve and the pipe joint is greatly reduced. The simplification of the system reduces the input and labor intensity of the maintenance pipe manpower.
6. The fire-fighting reservoir is not required to be specially arranged at the high position of a tunnel hole, can be flexibly arranged at the entrance or the exit of the tunnel according to the actual condition, is not required to be limited by the height difference like the traditional fire-fighting system, is an organic whole, and meets the purposes of timely and efficient fire-fighting water consumption.
