Anti-seismic foundation applied to subway and construction method

Abstract

The invention relates to an anti-seismic foundation applied to a subway. The anti-seismic foundation comprises an anti-seismic pillar, a bearing table foundation, steel fiber reinforced concrete, anti-seismic spring steel pieces, steel piece embedded parts, anti-seismic outer rigid cylinders, anti-seismic interior rigid cylinders, bearing table stressed ribs, bearing table frame vertical ribs, bearing table distributed ribs, vertical tie bars and oblique tie bars. The anti-seismic pillar stretches in the bearing table foundation. The anti-seismic spring steel pieces are arranged on the periphery of the anti-seismic pillar from top to bottom. The anti-seismic spring steel pieces are connected with the bearing table foundation and the end portion of the anti-seismic pillar through the steelpiece embedded parts. The outer sides of the steel piece embedded parts are provided with the anti-seismic outer rigid cylinders, and the steel piece embedded parts, the anti-seismic outer rigid cylinders and the anti-seismic interior rigid cylinders are of an integrated structure. The anti-seismic foundation has the beneficial effects that the anti-seismic spring steel pieces high in elastic limit and high in fatigue strength are arranged, and the effects of resisting earthquakes and eliminating energy are improved in the subway movement process of the foundation.

Description

technical field [0001] The invention relates to the field of subway anti-seismic technology, which can be used for anti-seismic shock absorption of subway foundations, in particular to anti-seismic foundations applied to subways, and in particular to anti-seismic foundations and construction methods applied to subways. Background technique [0002] With the rapid increase of the urban population and the continuous advancement of the urbanization process, the subway emerged as a new type of large-capacity public transportation. It overcomes the limitation of ground roads, opens up underground space, and effectively alleviates traffic congestion. The efficiency of urban traffic is improved, and the characteristics of using zero-emission electricity as the power also protect the urban landscape and ecology to a certain extent. Therefore, the subway has become an inevitable choice for the development of transportation in big cities. [0003] While the subway brings a series of ...

Problems solved by technology

[0004]In the process of this kind of vibration transmission, the horizontal vibration of the subway foundation is likely to cause shear damage to the foundation at the junction of the foundation and the horizontal cap

In the existing anti-seismic technology, there are many shortcomings such as poor recovery of the anti-seismic structure and large space occupation. The present invention mainly aims at the shear damage caused by this kind of horizontal vibration, and uses a kind of anti-seismic structure placed between the pile and the horizontal cap. Steel anti-seismic structure reduces the destructive effect on the premise of small space occupation and good structural recovery, prolonging the service life of the subway foundation
