Structural layout of subway stations and intervals and mechanized rapid construction method of structural layout

Abstract

The invention provides a structural layout of subway stations and intervals and a mechanized rapid construction method of the structural layout. The structural layout of the subway stations and the intervals comprises three parallel interval tunnel structures with a plurality of lengths in the longitudinal direction and the stations, wherein a station tunnel is arranged in the middle, interval tunnels are arranged on the two sides, the interval tunnels are train rail running areas, and the station tunnel and the interval tunnels are connected through communication channels. The mechanized rapid construction method of the structural layout of the subway stations and the intervals has the advantages of being small in comprehensive influence, high in construction speed, high in safety coefficient, few in abandoned engineering, good in quality guarantee and excellent in comprehensive benefit. By means of the new construction method, the early-stage work cost of house demolition, pipeline relocation and reconstruction, traffic guidance and reconstruction and the like can be greatly reduced, the construction period is shortened, and the capital cost is saved; in addition, the underground space development size is increased, the income is increased, and good economic benefits are obtained. Meanwhile, the influence of construction on infrastructure such as traffic and pipelines and the city image is reduced, and considerable social benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of subway and subway construction, in particular to a structural layout of subway stations and intervals and a mechanized rapid construction method thereof. Background technique [0002] The subway is an important measure to solve urban congestion. When constructing the subway, the design of the subway station plays a leading role. Its design scheme will be affected by many subjective and objective factors. Therefore, it is of great significance to design feasible, cost-effective, and functionally complete subway stations and sections. [0003] Traditional subway stations are generally constructed using methods such as open-cut method, cover-excavation method, and / or shallow buried and underground excavation method. Each construction method has its own advantages and has made great contributions to the construction of urban subways in my country, but they all have the following disadvantages: [0004] First...

AI Technical Summary

Problems solved by technology

[0004] First, various types of construction have a great impact on the image of the city, especially in the core areas, as well as traffic and commerce. The open-cut and cover-excavation subway stations generally need to occupy urban road traffic and carry out traffic reformation, which will have an impact on the flow of people in urban shopping malls, shops, etc. At the same time, construction noise, earthwork dust, greening migration, etc. will all have an impact on urban residents, especially on the city's traffic, commerce, comprehensive image and the production and life of the people for a long time;

[0005] Second, the cost of demolition is huge, coordination is difficult and time-consuming;

[0006] Third, open-cut and cover-excavated foundation pits and underground excavation tunnels require measures such as temporary enclosure structures and precipitation, which are expensive; fourth, they have a large impact on the environment, are prone to noise, and construction is significantly affected by the weather;

[0007] Fifth, labor-intensive and low degree of mechanization;

[0008] Sixth, the conversion of each process is complicated, and the shield machine needs to start and receive multiple times;

[0009] Seventh, the safety risk is high, it is easy to collapse, and the quality of waterproof and stucco is not easy to guarantee;

[0010] In addition, since the reinforced concrete structure is basically constructed on site, it is extremely difficult to guarantee the working conditions, limited environment, waterproofing and quality of the concrete, which may easily lead to unstable quality and insufficient concrete strength, honeycomb pockmarked surface, serious water leakage, which poses a threat to safe operation. bring great danger
