Embodiment Construction

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] see figure 1 Now, the earthquake protection device applied to the subway tunnel provided by the embodiment of the present invention will be described. The earthquake protection device applied to subway tunnels includes a main buffer 100 , a secondary buffer 400 and a force transmission mechanism 500 . The main buffer 100 is used to connect the primary lining 200 and the secondary lining 300 of the tunnel. The secondary buffer 400 has a fixed end and a force receiving end, and the fixed end is fixedly connected to the side wall of the main buffer 100 . The...

Abstract

The invention provides an earthquake protection device applied to a subway tunnel and a subway tunnel support system and belongs to the field of tunnel protection technologies. The earthquake protection device applied to the subway tunnel comprises a main buffer, an auxiliary buffer and a force transfer mechanism, wherein the main buffer is configured to be connected to a primary lining and a secondary lining of the tunnel; the auxiliary buffer is provided with a fixed end and a stressed end; the fixed end is fixedly connected to a side wall of the main buffer; and the force transfer mechanismis configured to be connected to the primary lining and / or the secondary lining and the stressed end of the auxiliary buffer, such that part of stress between the primary lining and the secondary lining is transferred to the auxiliary buffer, and the stress of the main buffer is reduced accordingly. The invention further provides a subway tunnel support system. Different from the conventional protection concept, the protection concept employed by the earthquake protection device applied to the subway tunnel and the subway tunnel support system is that an inner lining and an outer lining are flexibly separated, meanwhile, the stress of the main buffer is effectively reduced, and the risk of Y-direction tension and compression damages to the tunnel when an earthquake occurs is reduced.

Description

technical field [0001] The invention belongs to the technical field of tunnel protection, and more specifically relates to an earthquake protection device and a support system for a subway tunnel. Background technique [0002] With the improvement of my country's comprehensive national strength and the growth of population, the domestic demand for relieving traffic pressure is becoming increasingly urgent. As a kind of engineering building buried underground, subway is being widely built in my country's transportation engineering construction. In the past, most scholars generally believed that subway tunnels had better seismic performance due to the constraints of surrounding rocks. However, the multiple destructive earthquakes that occurred in recent years have forced us to focus on the seismic and disaster resistance of subway tunnels again. [0003] At present, there are two main anti-seismic measures for subway tunnels: 1. Set anchor rods in the surrounding rock and inje...
