Method for constructing underground garage under old building

Abstract

The invention relates to a method for constructing an underground garage, which has the characteristics that: structural stability of the original building, high construction speed and low cost are guaranteed. According to a technical scheme, the method for constructing the underground garage under the old building is characterized by comprising the following steps that: a, an underground diaphragm wall or a sheet-pile wall is poured at a position which is at least 1m away from an exterior wall around the building; b, a group of cross beams are poured at the foundation at the bottom of an overhead layer of the building, and the cross beams are integrally connected with foundation soil, the underground diaphragm wall or the sheet-pile wall to support the building; c, underground space is dug below the foundation soil of the building, an entire plate foundation layer is poured at the bottom of the underground space, and the entire plate foundation with underground piles and the underground diaphragm wall or the sheet-pile wall are integrally connected; d, a part of the underground piles are cut off between the foundation soil and the entire plate foundation and the rest underground piles are reinforced; and e, a slope is arranged on the ground and the slope is communicated with the underground space to be served as a passage for entrance and exit of vehicles.

Description

technical field [0001] The invention relates to a construction method, in particular to a method for constructing an underground garage under an old building. Background technique [0002] With the development of society, people's living standards are getting higher and higher; in recent years, the number of private cars has increased year by year, which has brought some social problems while facilitating people's travel.

Problems solved by technology

At present, the problem of difficult parking in the city is becoming more and more serious. The ground parking spaces and underground parking spaces are in short supply, and the charges are high, which causes inconvenience to people's work and life.

Especially in some old residential buildings and offices, there are no underground garages under the original ground buildings, and the parking problem is particularly prominent. Car owners can only park their vehicles on the roads in the community, or on the roadside near the community. , this will make the roads in the community congested, prone to vehicle scratching accidents, and lead to some unnecessary disputes
