Design construction method for even fight combining with underground automobile garage mouth

Abstract

The invention discloses a design and construction method for a mouth part of a peacetime and wartime combined underground garage, and the method adopts the prior construction technology of the current construction project. A sinking-mode underground small-sized structure foundation which is in a pit shape is built at the mouth part. The structure foundation comprises an atrium, a civil air protective passageway, a civil air sealing passageway, a peacetime ventilation plant room and an air collecting chamber. The structure foundation is communicated with the underground garage by a fire door, a clear glass component for natural illumination and ventilation is adopted at the ground outdoors, and a clear glass head cover and a clear glass water retaining and clear glass ventilation grills are provided. A floor slab of a wall body under the ground outdoors adopts a reinforced concrete structure, the wall body is provided with a normally open civil air protective sealing valve, and clear fireproof glass is arranged behind the normally open civil air protective sealing valve for natural illumination. A protruded ground section of an implementation structure foundation of the invention is built by the clear glass, thereby having favorable natural illumination effect. A built ventilation passageway provides a favorable air inlet and outlet condition for forming a comfortable indoor environment.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a method for designing and constructing the mouth of an underground garage combined with peacetime and wartime. Background technique [0002] Article 22 of the current Civil Air Defense Law of the People's Republic of China stipulates that for new civil buildings in cities, basements that can be used for air defense during wartime shall be built in accordance with relevant state regulations. Relevant state departments also stipulate that for newly-built civil buildings with more than 10 floors or with a foundation buried depth of more than 3 meters and below 9 floors, an anti-aircraft basement corresponding to the building area of ​​the first floor should be built. [0003] Due to the promulgation of the Civil Air Defense Law, a large number of air defense basements have been built in urban construction projects in my country. Both the air defense basement and the undergr...

AI Technical Summary

Problems solved by technology

[0008] Based on the above technical background, the disadvantages of the basement car garage combined in peacetime and wartime are: the outdoor entrances and exits of civil air defense are generally covered by prefabricated components, and the exits are not fully utilized in normal times; ventilation shafts are generally set separately , only has a single ventilation function, and most of the ventilation shafts protrude from the ground, which affects the landscape design of the community; the basement garage is a closed space, generally only artificial lighting, but no natural lighting, on the one hand, waste of electricity, on the other hand, lack of architecture environment, giving people a feeling of depression
