High-containment first-stage structure for property development of reserved vehicle depot and construction method

Abstract

The invention provides a first-stage structure for property development of a high-containment reserved vehicle depot and a construction method, the first-stage structure comprises a vehicle depot large warehouse and a reserved hole, the vehicle depot large warehouse is arranged on the outer side of the reserved hole and used for storing metro vehicles, and a high-rise building foundation is constructed at the bottom of the reserved hole. A single line span, a small flat column, a single pile, a crown beam and the like are arranged in a large garage close to a vehicle depot beside a hole, and are completely separated from a high-rise building and a foundation of the high-rise building. According to the first-stage structure and the construction method, the vehicle depot large garage can be constructed under the condition that the house type of the high-rise building is uncertain, the house type of the later-stage high-rise building is flexible, adjustable and high in inclusiveness, normal operation of a subway is not affected by construction, and the vehicle depot large garage and the high-rise building are of an independent structure anti-seismic calculation unit; the height of the high-rise building is not limited by the conversion structure, and the area of the developable building is greatly increased. Land resources are saved, meanwhile, it is guaranteed that the structure of second-stage implementation has construction feasibility, and the problem of differential settlement between a high-rise building and a large warehouse is solved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a first-phase structure and construction method for property development of a highly inclusive reserved depot. Background technique [0002] The subway depot is the location of the management center for the parking, inspection, maintenance, operation and repair of subway vehicles. It usually covers an area of ​​300-500 mu according to different functions and scales. In order to save land resources, TOD (Transit Oriented Development), that is, public transport-oriented development model, came into being. As a land use model based on overall planning, it provides a new development model that organically combines transportation construction and land use for urban construction. It is also a construction model that has been rapidly developed and widely used in current domestic and foreign transportation planning and construction. . [0003] The large warehouse under the cover plat...

AI Technical Summary

Problems solved by technology

Full conversion or partial conversion schemes have high requirements for structural anti-seismic fortification, strict review of overruns, limited building height, and complex forces on beams and columns for conversion, and high construction costs, resulting in low comprehensive income for projects in some areas

Although the existing full-floor form has a high building height and low cost, it requires the building type to be determined and built synchronously with the depot large warehouse until the height of the cover plate of the large warehouse can be implemented in the later stage. The fixed type of apartment cannot adapt to the changing needs of the market and falls into a slow market. huge risk
