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

Embodiment Construction

[0033] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0034] Firstly, the definition of the double zero condition is given. The first is that the structures to be built later pass down through the existing buildings at zero distance;

[0035] The second is that the existing buildings meet zero settlement during the entire construction process of the existing buildings and subsequent structures.

[0036] Such as figure 1 Shown is the structure of the embodiment of the present invention. The specific structure is described as follows:

[0037] An underground engineering structure that satisfies the double-zero condition, including an existing building 8, an underground structure, including an adjusta...

Abstract

The invention discloses an underground engineering structure meeting the double-zero condition. The underground engineering structure comprises an existing building and an underground structure, and further comprises an adjustable supporting body, an air pressure monitoring device, a deformation monitoring device and a building bottom plate; the existing building is built on the building bottom plate, the underground structure is arranged below the existing building, and the deformation monitoring device is arranged on the building bottom plate; the underground structure comprises an underground space, supporting enclosures and pile foundations, the underground space is located below the existing building, the two supporting enclosures are oppositely arranged in the underground space, thepile foundations are arranged in the underground space, and the pile foundations are located between the two supporting enclosures; and adjustable supporting bodies are correspondingly arranged at thetops of the supporting enclosures and the pile foundations, and the upper ends of the adjustable supporting bodies abut against the building bottom plate. An inflatable air bag and a one-way exhaustvalve can be prefabricated and installed in advance in a factory, the air bag body is inflated conveniently through an inflator in the construction process of a subsequent building structure, and thewhole construction process is simple, convenient and rapid.

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...
