Problems solved by technology

[0011] The purpose of the present invention is to provide an evacuation platform that can resist high wind pressure by increasing the thickness of the evacuation platform in the prior art, resulting in increased load on the evacuation platform and difficulty in manual installation. High wind pressure rail transit evacuation platform, the evacuation platform can realize the design effect of thinning the thickness of the platform plate, and at the same time not only can resist the high wind pressure of the tunnel, but also can effectively reduce the installation and construction intensity of workers

Embodiment

[0045] The rail transit evacuation platform provided in this embodiment is mainly used for evacuating people when a fire or other emergency occurs in a rail transit tunnel, and is especially suitable for rapid subway lines with a design speed of ≥140km / h, and can resist design speeds of ≥140km / h. h high wind pressure generated by the rapid subway line.

[0046] Such as Figure 1-4 As shown, the rail transit evacuation platform includes a pier 2 and a platform plate 9, and the platform plate 9 is detachably installed on the pier 2, and the detachable connection includes threaded connection, buckle connection, hinge connection, pin connection or Key connection and other connection methods, the platform plate 9 can choose to adopt a monolithic structure, but from the perspective of reducing the weight of the platform plate, adjusting the size of the tunnel and adapting to the limit value of the evacuation platform plate, it is preferred to use such as image 3 In the assembled s...

Abstract

The invention discloses the technical field of rail transit facilities, and in particular relates to a rail transit evacuation platform that can resist high wind pressure. The rail transit evacuation platform includes a support pier and a platform plate installed on the support pier. It is a concrete composite material, the platform slab includes a standard block and an adjustment block, and the standard block and the adjustment block are spliced ​​to form a platform slab, and both the standard block and the adjustment block are connected to the pier through a wind pressure resistant bolt assembly The detachable connection, the evacuation platform is made of concrete composite material, which reduces the workload of maintenance, maintenance and replacement in the later operation process, and reduces the maintenance cost. In the technology, the heavy weight of the monolithic platform slab leads to the difficulty of installation. Both the standard block and the adjustment block are detachably connected to the pier through wind-resistant bolt components, which solves the problem that cannot be solved in the prior art. Solve or only rely on increasing the thickness of the platform slab to resist high wind pressure, which will increase the load of the pier and affect the bearing performance.

Description

technical field [0001] The invention relates to the technical field of rail transit facilities, in particular to a rail transit evacuation platform capable of resisting high wind pressure. Background technique [0002] In the case of fire or other emergencies in the rail transit tunnel, it is necessary to evacuate the passengers in the car. As one of the main evacuation paths, the evacuation platform is very important. Due to the influence of the piston wind, the stability of the evacuation platform is the key to the stability of the rail transit tunnel. Factors that need to be considered in the design process. [0003] Piston wind means that the train running at high speed in the tunnel will drive the air in the tunnel to generate high-speed flow, similar to the piston compressed gas in the cylinder. When the high-speed train enters the tunnel, the air in the tunnel is still, and high-pressure waves are generated due to the impact of the train. , the high-pressure wave pro...
