Description
Technical Field
The utility model belongs to the technical field of tunnel ventilation equipment, concretely relates to quick discharging equipment of tunnel gas.
Background
In recent years, with the development of engineering technology and society, tunnel engineering projects such as highways, high-speed railways and water diversion projects are increasing, and gas-containing geology such as coal beds and goafs is inevitably encountered. At present, the construction of a gas tunnel mainly refers to the mature technology of dealing with gas in a coal mine, and a set of feasible methods is formed. The forced aeration dilution method (reducing it to below non-explosive concentrations and below concentrations harmful to humans and gradually extruding it out of the hole) is generally used. The corresponding safety regulations enforce that the wind speed in the tunnel is required to be not less than 0.15m/s in the common tunnel, the minimum wind speed in the coal mine tunnel is required to be not less than 1.0m/s, and the minimum wind speed in the gas tunnel is also not less than 1.0m/s in reference to the execution of the coal mine standard. Compared with the ventilation quantity of a gas tunnel, the ventilation quantity of the gas tunnel is more than 7 times of the ventilation quantity of a common tunnel. Before the tunnel engineering is started, safety risk assessment must be made according to geological drilling reports, and when the construction ventilation design of tunnels with gas exposure risks, ventilation equipment is calculated and configured according to the ventilation standard of the tunnels with gas.
During the construction of a common tunnel, two modes of continuous ventilation with small continuous air volume and enhanced ventilation with large short-time air volume are generally adopted for ventilation. The main task of the continuous ventilation is to maintain the instant supplement of oxygen consumption of constructors, construction machinery, construction blasting and the like, and simultaneously has the function of diluting the concentration of harmful air; the intensified ventilation is a high-speed, high-pressure, large-air-volume and short-time ventilation mode, quickly dilutes high-concentration harmful air below safe concentration, and pushes the harmful air out of the tunnel under the action of air pressure. Gas tunnels typically employ only one form of forced ventilation.
The prior art has the following problems:
in a longer tunnel, the section with the risk of gas exposure is often shorter, only occupies a part of the tunnel, but in order to ensure the construction safety, ventilation equipment must be configured according to the ventilation standard of the gas tunnel. Meanwhile, the gas exposure is not all high-concentration gas, sometimes the concentration is very low, but as long as the gas is detected, the enhanced ventilation is carried out according to the standard of a gas tunnel.
In a gas tunnel which is not communicated, a gas exposure area is mainly distributed in a construction area between a driving face and a secondary lining, when construction passes through the gas area (coal bed, goaf and the like), if the gas exposure is small, the concentration is low and the duration is long, the ventilation cost is extremely high by adopting an enhanced ventilation mode for a long time, and meanwhile, the continuous working failure rate of ventilation equipment is high.
