The equipment and the method of the invention can be used for carrying out experimental study on generation and development mechanism, ventilation, smoke discharge, control and prevention of the cavern fire in the hydraulic and hydro-power engineering, and providing reasonable and correct scientific proofs for engineering design and operation of underground caverns construction and fire safety of construction.

Description

technical field [0001] The invention relates to the technical field of fire experiment simulation, in particular to fire simulation experiment equipment and a simulation experiment method for cavern groups in water conservancy and hydropower projects. Background technique [0002] Water conservancy and hydropower projects built in deep mountains and valleys usually involve multiple large-scale underground caverns consisting of underground powerhouses, main transformer rooms, water inlet and tailwater tunnels, busbar tunnels, traffic tunnels, flood discharge tunnels, and diversion tunnels during construction. Underground caverns. Since the caverns are interconnected and the organization of ventilation and smoke exhaust is difficult, if a fire accident occurs during construction and operation, the process of fire and smoke spread will be very complicated. Therefore, it is urgent in the field of water conservancy and hydropower engineering to explore the smoke spread and venti...

Problems solved by technology

However, the applicable objects and applicable functions of these experimental systems are relatively single, and generally can only meet the specific needs of certain types of projects; at the same time, their tunnel structures are relatively simple, which is difficult to meet the needs of large-scale tunnels composed of long tunnels and tall caverns. The needs of room group fire simulation experiment

[0004] At present, there is no domestic experimental platform for fire accident simulation for water conservancy and hydropower project caverns. Therefore, how to establish a multi-functional large-scale experimental system platform for fire accidents in water conservancy and hydropower project caverns to carry out space fires in underground caverns It is an urgent problem in the field of water conservancy and hydropower engineering to provide reasonable and accurate scientific basis for the delay management of the design, construction, operation and maintenance of water conservancy and hydropower caverns by the experimental simulation of spreading and the experimental research of accident ventilation and smoke exhaust
