Embodiment 1

[0026] Embodiment 1, the present invention is a tunnel anti-seismic device for crossing thermal faults, including a tunnel body 1, a support bracket 2 is built inside the tunnel body 1, and the support bracket 2 provides fixation for subsequent structures. Support the foundation, and at the same time support the collapse of a small area in the tunnel through the support bracket 2, avoiding the collapse of the collapsed objects falling into the tunnel, causing safety accidents to personnel and traffic, the support bracket 2 and the tunnel body 1 are fixedly connected with several groups of anti-seismic devices, the left and right directions of the anti-seismic devices are distributed in the same circle, and the anti-seismic devices are distributed alternately in the front and rear directions, and the tunnel body 1 is fully supported by the anti-seismic devices, so that The tunnel body 1 will not collapse in a large area during the earthquake, wherein the original tunnel structur...

Embodiment 2

[0031] Embodiment 2, on the basis of Embodiment 1, in the event of a major earthquake disaster, the tee pipe 3 will fall off to a certain extent under the impact of strong seismic waves, and then the support will fail. Therefore, this embodiment provides a Buffer the tee pipe 3 after falling off to ensure the stability of the function of the anti-seismic device. Specifically, the outer wall of the right connecting rod 9 is covered with a protective sleeve 16, and the protective sleeve 16 The lower end of 16 is fixedly connected with the support bracket, and the right end of the right connecting rod 9 is fixedly connected with a protective spring 17, and the protective spring 17 is fixedly connected with the protective sleeve 16. After the pipe 3 and the support bracket 2 fall off, under the influence of earthquake waves, the three-way pipe 3 will tend to slide, and at the same time, during the sliding process of the three-way pipe 3, the protective spring will 17 buffers the f...

Embodiment 3

[0032]Embodiment 3. On the basis of Embodiment 2, during the earthquake, the side wall of the tunnel will shake to a certain extent. In order to have an impact on the side wall of the tunnel, this embodiment provides a The inner wall of the tunnel is buffered. Specifically, the left and right side walls of the support frame 2 are fixedly connected with a buffer device, and the seismic wave on the inner wall of the tunnel is buffered by the buffer device. The buffer device includes several limit sleeves 18 that are fixedly connected with the support bracket 2, and the inside of the limit sleeve 18 is slidingly connected with a telescopic rod 19 that is connected to the inner wall of the tunnel. The telescopic rod 19 is connected to the inner wall of the tunnel through a telescopic spring, and the telescopic rod 19 will slide relative to the deformation of the inner wall of the tunnel, while the telescopic rod 19 compresses the telescopic spring, and the The above-mentioned tele...

Abstract

The invention provides a tunnel anti-seismic structure used for crossing a heat conduction fault, and solves the problems that when a tunnel is supported in the prior art, only a main body is supported, small-range collapse and falling cannot be avoided, and meanwhile objects and people in the tunnel cannot be protected in the collapse process. The anti-seismic tunnel comprises a tunnel body, a bearing frame is arranged in the tunnel body, a plurality of sets of anti-seismic devices are fixedly connected between the bearing frame and the tunnel body, the anti-seismic devices are distributed on the same circumference in the left-right direction, the anti-seismic devices are distributed in a staggered mode in the front-back direction, and each anti-seismic device comprises a connecting three-way pipe fixedly connected with the bearing frame; the upper end of the three-way pipe is vertically slidably connected with an upper sliding rod, the upper end of the upper sliding rod is fixedly connected with an arc-shaped supporting plate, an upper piston plate is vertically slidably connected into the three-way pipe and connected with the lower end of the three-way pipe through a buffer spring, and the left end and the right end of the three-way pipe communicate with a left communicating rod and a right communicating rod correspondingly. The device is exquisite in structure and has very high practicability.

Description

technical field [0001] The invention relates to the technical field of tunnel support, in particular to a tunnel anti-seismic structure for crossing thermal faults. Background technique [0002] Due to the influence of geological characteristics, it is necessary to comprehensively consider the geological characteristics of the rock mass during the construction of the tunnel in the thermal fault zone. At the same time, earthquakes have occurred in the thermal fault zone, causing the tunnel to collapse or affect the normal operation of the tunnel. It will even lead to huge safety accidents, causing huge losses of people's lives and property. At the same time, due to the interruption of traffic, it will affect the development of earthquake relief. loss of people's property. [0003] However, at present, there are many problems in the process of seismic support of tunnels as follows: [0004] 1. At present, most of the supporting structures are supported by pouring prefabricat...
