Description
Technical field
The present invention relates to a kind of rail rapid transit engineering hydraulic vertical rotary flood and preventive airtight blast door, belong to protection airtight every
Disconnected gate technique field.
Background technology
Most of City Rail Transit System is all the passenger for delivering city commuting, and city in many instances
City's Rail Transit System can all be treated as the backbone of urban transportation.At war (such as World War II), subterranean railway is also
Factory or bomb shelter can be used as.The subway system of many countries (such as South Korea), war may be calculated by having in design
In design, so the either depth of railway, crowd's control aspect, the needs of daily traffic and national defence are all taken into account simultaneously.
Subway engineering is usually City Underground Transportation arterial highway, wartime be urban civil air defense main passage for evacuation, material storage storehouse,
Personnel portion to be covered or personnel shelter.Usually each station, running tunnel are interconnected, and are open to traffic, and wartime can then separate
Into separate protective unit.The division of protective unit be using underground station plus coupled running tunnel section as
One independent protective unit.Safeguard and internal unit are supporting into autonomous system in each protective unit, establish one's own system, wartime
Air defense, usually take precautions against natural calamities.Require to have between each protective unit and can bear bidirectional load and the interval partition door with sealing function.It is close
Close partition door and allow for bearing certain pressure even shock wave of nuclear explosion, it is necessary to reach certain people's air defense grade.And
Obturation effect is very good, can prevent the seepage of malicious gas and water.
Often there is the situation that section is crossed in underground urban subway, it is common practice to the both ends of section are crossed in section
Flood gate and partition door are individually set.This traditional method compares waste of resource, in construction and installation and later maintenance
Difficulty is larger.In order to save civil engineering and equipment investment, accomplish to construct, install and use, be easy to maintenance, " under underground railway waters
Running tunnel Flood gate be combined with people's air defense section protective airtight partition door " by be subway construction from now on trend.Subway area
Between protective airtight partition door as the handling characteristics of Flood gate be when river bed section running tunnel is closed by Flood gate when destroying
Action is closed, generally, no matter being all anhydrous in running tunnel, therefore, the Flood gate is typically at normally opened shape usually or wartime
State, although needing typically to have certain omen sign when closing Flood gate, when when turning off Flood gate with certain reaction
Between, but design is also required to make it have the function that operation is opened and closed under moving water state.So the design of partition door just seems
It is particularly important.It must account for its closing property, load people's air defense drag rank (Subjected To Biaxial Loading), door leaf upstream face stress hydraulic pressure
Situation, and door leaf closing direction and water (flow) direction are relation of following current or adverse current etc..
The anti-Mi Men of flood is divided into rotatable two class of vertical lift type, hydraulic vertical by switch pattern, and wherein lift is divided into volume again
Raise machine formula and electric block type.Lift is similar with traditional water conservancy Flood gate, located at the position with two layer of space, usually puts
It is placed in station hall layer, fall during closing cut-off station layer tunnel.More city underground buried depth is shallower, and vertical lift type needs 7 up and down
~8 meters of space, difficult arrangement, the rotatable door of hydraulic vertical is devised for the situation.The Men Li, which is turned on, to be opened, for infer bus-bar or
Close the door against the current, need stronger shutdown drive mechanism.And meeting the nervous requirement of tunnel space, hydraulic push rod mechanism needs to provide
320KN door closing force.But for the rail tunnel of large space, vertical rotary type sealed door size used just needs to do
It is very big, but its deadweight increase is more simultaneously, and this just proposes higher requirement to hydraulic push rod mechanism, and there has been no have at present
The solution of effect.
