An underground engineering structure and construction method satisfying the double zero condition

Abstract

An underground engineering structure that satisfies double-zero conditions, including existing buildings and underground structures, and also includes adjustable supports, air pressure monitoring devices, deformation monitoring devices and building floors; existing buildings are built on building floors, and underground structures It is installed under the existing building, and a deformation monitoring device is installed on the building floor; the underground structure includes underground space, support enclosure and pile foundation. For protection, a pile foundation is set in the underground space, and the pile foundation is located between two supporting enclosures; an adjustable support body is arranged on the top of the support enclosure and the pile foundation, and the upper end of the adjustable support body abuts against the building floor . The inflatable airbag and the one-way exhaust valve can be prefabricated and installed in the factory in advance, and it is convenient to use the inflator to inflate the airbag body during the construction of the subsequent construction of the structure, and the whole construction process is simple and fast.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to an underground engineering structure and construction method satisfying double-zero conditions. Background technique [0002] my country's national economy is developing rapidly, and the level of urbanization is constantly improving. The development of the city has led to a sharp increase in the urban population. The growth of the population has made the public transportation more and more congested, and the urban land is in short supply. The development of urban underground space can effectively improve the current situation of urban congestion and make full use of land. The development of underground engineering will inevitably encounter many underground access projects, which will inevitably cause disturbance to the surrounding strata during the construction process, and then affect the existing buildings. Especially when underground tunnels pass through existing buildings a...

Problems solved by technology

It is difficult to use reinforced concrete piles in underground construction, and it takes a certain time for reinforced concrete piles to play a role, the construction period is long, and the project cost is high; and reinforced concrete piles only passively limit the settlement and deformation of existing buildings, and cannot actively control the existing Settlement Deformation of Buildings
