The utility model has the beneficial effects that the facility can effectively cut station micro-pressure wave peak values so as to enable the wave peak value to meet the requirement for environmental design, reduce pressure peak values and pressure gradients nearby the station platform by about 20 percent, and effectively mitigate the aerodynamic effect caused by a high-speed train which breaks into the underground station from the tunnel, so that the pressure peak values and pressure fluctuation indexes in the station are reduced to meet the comfort standard of waiting staff in the station platform.
Description
Technical field
The utility model relates to high speed railway, particularly a kind of Pneumatic effect releasing facilities for underground bus stop of high-speed railway.
Background technology
Along with the development of communication and people at a high speed, the demand of the vehicle of quick, environmental protection, high speed railway becomes the metropolitan preferred traffic mode that connects.Yet the day of urban land is becoming tight, and railway is introduced the down town will become more and more difficult.Develop the underground space energetically and make the sustainable development in city become possibility, therefore build the new trend that the railway underground station will become the railway traffic development gradually.
When train passes through the tunnel at a relatively high speed, will in the tunnel, produce obvious pressure fluctuation and cause micro-pressure wave phenomenon, and then have influence on the traveling comfort of passenger in the train and the living environment around the tunnel in the exit.Along with the raising of train speed, this aerodynamic effects can be more and more significant.And as being present in underground railway station, circuit is many, platform is many, and the factors such as (not stopping) train passes through a station at a high speed of missing the stop will cause a series of aerodynamics problem and threaten the problem of passenger and staff's safety.This also is a problem demanding prompt solution in the Develop High-Speed Railway process.
According to the existing high speed railway design regulation of the Ministry of Railways, during less than 50m, micro-pressure wave should be less than 20Pa at the distance tunnel portal.If do not adopt fender system that the micro-pressure wave peak value is cut down, when high speed train during by tunnel and underground station, can't satisfy the Environment Design requirement of this minute-pressure crest with the speed more than the 200km/h.
The utility model content
Technical problem to be solved in the utility model provides a kind of Pneumatic effect releasing facilities for underground bus stop of high-speed railway, and this releasing facilities can be cut down micro-pressure wave peak value in standing effectively, makes it to reach the requirement of design regulation.
The technical scheme that its technical matters that solves the utility model adopts is: Pneumatic effect releasing facilities for underground bus stop of high-speed railway of the present utility model, comprise the underground space that vertical two ends communicate with the tunnel, and be arranged on the interior platform of this underground space, it is characterized in that: form horn-like gradual change by transition phase between the interlude of described underground space sidewall and the tunnel inner port.
Described platform is by laying respectively at center line both sides, tunnel, main track and constituting to two island platforms the hair line.
The entrance in described tunnel is provided with the ground-surface buffering well of pass-out at its top along tunnel center line longitudinal interval.
Described tunnel latter end is provided with the ground-surface decompression vertical shaft of pass-out at its top along the tunnel center line, and this decompression vertical shaft closes on the inner port in tunnel.
Described island platform is provided with shielded gate along its periphery.
The beneficial effects of the utility model are, the transition phase of horn-like gradual change can be cut down micro-pressure wave peak value in standing effectively, the buffering well that is arranged on entrance can be cut down near the micro-pressure wave peak value the tunnel portal effectively, make it to satisfy the requirement of Environment Design, and eliminate the generation of micro-pressure wave in the station.The decompression vertical shaft that is arranged on the tunnel latter end can reduce about 20% with near pressure peak the platform and pressure gradient, caused aerodynamic effects when alleviating high speed train effectively and having the tunnel to charge into the underground station, make pressure peak and fluctuation of pressure index in the station be reduced to the comfort criterion that satisfies the personnel that wait in the platform, thereby waiting environment in the raising underground station and comfort level effect, and help satisfying the designing requirement of shielded gate, to reduce the laid down cost of underground station.
