Description

Technical Field

[0001] The utility model belongs to the technical field of concrete structure bearing capacity, and specifically relates to a reinforcement system for improving the bearing capacity of an existing subway vehicle depot operation warehouse structure. Background Art

[0002] Urban rail transit is the backbone of urban public transportation. It is energy-saving, land-saving, large-capacity, all-weather, pollution-free (or less pollution) and safe. It is a green and environmentally friendly transportation system, especially suitable for large and medium-sized cities. With the continuous expansion of urban scale, subway construction is the only way for each city to expand. However, in the new era, with the continuous changes in the national development strategy, the pace of urban expansion has slowed down, and urban transformation and maximizing the use of existing urban land resources have become the focus of urban development.

[0003] The original subway depot parking lot was built in the open air, occupying too much land and with low space utilization. With the rapid development of the city, the original similar open-air infrastructure cannot adapt to the development needs of the new urban pattern. At the same time, this type of infrastructure is in operation and the subway cannot be shut down for demolition, renovation and reconstruction. More and more old infrastructure concrete projects are restricting urban development.

[0004] Similar subway depot warehouses have existed for a long time, and their structural functions cannot meet today's usage needs. Therefore, they are facing the fate of being renovated. For these old concrete structures, the general treatment method is mostly to dismantle and modify them, but this method is time-consuming and costly, and will generate too much construction waste; at the same time, the corresponding functions cannot be used temporarily, which reduces the quality of life of urban residents. That is, it is time-consuming and labor-intensive, and generates a lot of waste. Based on the above needs, a reinforcement system is needed to improve the structural bearing capacity of the existing subway depot warehouse, reduce costs, and increase benefits. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides a reinforcement system for improving the structural bearing capacity of an existing subway vehicle depot, comprising a plurality of arranged foundation caps, a foundation beam being arranged horizontally between two adjacent foundation caps, two ends of the foundation beam being respectively fixed at the upper ends of opposite sides of the two foundation caps, and a vertical structural column being fixed at the upper end of each foundation cap;

[0006] The foundation cap is composed of an existing cap and a newly built cap, wherein the existing cap and the newly built cap are combined into a new cap by planting reinforcement, and the newly built cap is arranged on the side of the existing cap by two cast-in-place piles.

[0007] Furthermore, when the original cap is a four-pile cap, the original cap and the newly built cap are combined into a new four-pile rectangular cap by planting reinforcement; when the original cap is a six-pile cap, the original cap and the newly built cap are combined into a new octagonal six-pile cap by planting reinforcement; when the original cap is an eight-pile cap, the original cap and the newly built cap are combined into a new octagonal ten-pile cap by planting reinforcement.

[0008] Furthermore, a plurality of first steel bars are arranged in sequence along the length direction on the four sides of the foundation beam, the first steel bars are perpendicular to the length direction of the foundation beam, and the lower edge of the foundation beam is wrapped by a first angle steel.

[0009] Furthermore, the four edges of the structural column are all wrapped by second angle steels, and a plurality of second steel bars are sequentially arranged between two adjacent second angle steels.

[0010] The advantages of the utility model are as follows: the utility model provides a reinforcement system for improving the structural bearing capacity of the existing subway vehicle depot, and solves the problems of long construction period, high cost and serious waste caused by the need for demolition and modification of the original concrete structure foundation due to insufficient structural bearing capacity, by increasing the bearing capacity of the foundation pedestal, improving the bearing capacity of the foundation beam and strengthening the structural strength of the structural column.
