The following methods are used to deal with architectural design.
Firstly, by utilizing a traditional building design method and combining a certain new technical means, the ventilating shaft to be exposed out of the outdoor ground is integrated and then arranged inside the main building, and the ventilating shaft appears in the form of a certain design element in the vertical surface model of the main building, so that the 'stealth' of the ventilating shaft is realized. This is applicable when all or most of the area of the underground structure is contained within the projected line of the ground structure, and only a small amount of the area is located below the ground of the outdoor square of the structure.
Secondly, natural ventilation of underground buildings is carried out by utilizing a building design method with an ecological concept and by arranging a sunken courtyard, so that the traditional method (arranging a ground ventilation shaft on an outdoor square) is replaced. The design mode not only perfectly hides the ventilation shaft of the underground building, but also is more beneficial to environmental protection and energy conservation of the building.

Detailed Description
The following describes the present invention in further detail.
As shown in fig. 1, the self-pressing building ventilation shaft of the present invention is a multi-storey building, which has 2 floors underground and 12 floors above ground. Including ventilation shaft 4 and elevartor shaft 1 in the building, be provided with elevator car 2 in the elevartor shaft 1, 1 bottom of elevartor shaft is provided with an air suction channel 5 and a pressurized air passageway 7, be provided with a compressible utricule 3 between 2 bottoms of elevator car and the 1 bottom of elevartor shaft, compressible utricule 3 is the rubber capsule body, the one end sealing connection of compressible utricule 3 bottom and air suction channel 5 and pressurized air passageway 7, air suction channel 5 is provided with an air suction check valve 6 with the 3 junction of compressible utricule, be provided with an air supply check valve 8 in the pressurized air passageway 7, the 5 other ends of air suction channel accesss to the outside ground of building, the 7 other ends of pressurized air passageway and ventilation shaft 4 intercommunication. Each layer in the ventilation shaft 4 is provided with an openable ventilation plate 10. The compressed air channel 7 is U-shaped, and two ends of the compressed air channel are respectively connected with the bottom of the ventilation shaft 4 and the bottom of the elevator shaft 1.
When the elevator car 2 ascends, the compressible bag body 3 is driven to be pulled up and expanded, so that the air suction one-way valve 6 is opened, the air supply one-way valve 8 is closed, and the compressible bag body 3 absorbs air from the air suction channel 5; when elevator car 2 descends, induced draft check valve 6 closes, and air supply check valve 8 opens to air in sending into ventilating shaft 4 through pressing wind passageway 7 in with compressible utricule 3 and rising, and promote each layer ventilating board 10 and upwards open, thereby drive each layer air and discharge from ventilating shaft 4 top, greatly improved ventilating shaft 4's ventilation effect. In order to prevent the headwind, when air is filled into the top of the ventilation shaft 4, the ventilation board 10 is pushed to be closed.
