Description
Technical field
This utility model belongs to underground engineering construction field, and this utility model is related to one kind and is tied with uplift pile using Y shape pillar
The structure at design large span deep buried metro station is closed, the top using y-type structure post when subway underground structure is designed is specifically referred to
Part fork fulcrum reduces underground structure top board span, reduces base plate span using base plate uplift pile, so as to create between roof and floor
The method for designing in space is used compared with large span.
Background technology
As the fast development in current city, land supply are nervous, space is wanted increasingly to be taken seriously to underground, it is complete at present
The state overwhelming majority is building or is planning to build subway in big city.
With the expansion of subway construction scale, buried underground station is more and more, and generally such station has larger bottom
Portion's hydraulic pressure and larger top earthing and overburden pressure.If more three layers of underground station bottom hydraulic pressure is up to 220kPa, four layers of car
Bottom hydraulic pressure stand up to 300kPa, top board vertical load includes that deadweight, earthing, overcharge on ground also have 100kPa or so.To solve
So big top/bottom part load, more than the structure design of current subway open-cut station using 8 ~ 10m standard span, structural column adopts
Right cylinder, this span limit the arrangement of space to a certain extent, have larger obstruction to passenger flow, and inter-visibility is poor, perception
Also it is poor.As bottom hydraulic pressure is larger, such buried station generally leans on earthing and dead load meet anti-floating requirement, needs
Other measure of anti float, such as ballast, capping beam, uplift pile, anti-float anchor rod etc. are set, and we generally consider for uplift pile etc. to be located at post
Under, just with uplift pile anti-floating act on, and ignore which can be used as fulcrum force, the cross-cut to base plate under base plate
Effect.
There is other features at the buried station of subway open cut：1st, middle plate stress is less, generally only 5 ~ 10kPa or so, middle plate
The impact that span increase brings is less；2nd, the main use space of passenger is in station hall layer and station layer.
Need badly in sum and open up a kind of new mentality of designing, roof and floor structure can be rationally solved under the conditions of buried and be received
Power problem, can increase station subway concourse again and the passenger of station layer uses space.
Station is had at present by simply significantly increasing roof and floor, beam section size and arrangement of reinforcement to create long-span space,
Structure floor height is sacrificed to a certain extent, and economy is also poor.
Utility model content
Ask to solve station layer and station hall layer larger use space, the larger design load of roof and floor, structural anti-buoyancy

Feature, by the innovation of rational component arrangement form, has reached and has made full use of the underground space, the mesh of reasonable distribution structure stress
's；
2nd, this utility model is for the usual top plate earth-covering load of subway underground structure is larger, buried underground station base plate hydraulic pressure
Greatly, common station structure span is little, intensive post net, inconvenient use the characteristics of, adopt Y when the buried underground structure of subway is designed
The top bifurcated fulcrum of type structural column reduces underground structure top board span, reduces base plate span using base plate uplift pile, so as to create
The method for designing for using space between roof and floor compared with large span is made, in the case where construction costs is not improved substantially, is rationally solved
Top board and base arrangement stress, solve the problems, such as that passenger uses space post net intensive again, improve the comfortableness that station uses；
3rd, under the background of subway Large scale construction, this utility model can be rationally and effectively to be provided using the underground space
More preferable thinking.
