Problems solved by technology

In the impact test, it is often necessary to make an impact platform to test the parameters of the impact resistance performance of the motor vehicle. During the impact test, the EMU runs at high speed on the track and impacts the impact platform. The tail will swing sideways, throw off the track or rollover, hit the surrounding buildings, and threaten the safety of the surrounding testers. The impact will also cause mechanical damage to the rear of the train, causing unnecessary economic losses

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 , 2 , 3, 4, and 5, the construction process of the special protective piles for the impact test platform of the EMU car body includes the following steps:

[0024] (1) Set up the main protection pile casing: erect the main formwork for pouring the impact platform foundation 1, each main formwork forms the main pouring area, and lay horizontal and steel bars and support in advance along the edge of the impact platform foundation 1 in the main pouring area The main protective pile casing 2 is laid, and the distance between two adjacent main protective pile casings 2 is 1.5m. The bottom of the main protective pile casing 2 is welded to strengthen and impact the platform foundation 1. The reinforcing steel bar 3 of connection strength is fixed with the horizontal and vertical steel bars, and the bottom end of the...

Abstract

The invention discloses a protection pile construction process special for a motor train unit train body impact test platform. The protection pile construction process comprises the following steps that 1, a main protection pile sleeve is arranged; 2, an auxiliary protection pile sleeve is arranged; 3, a pre-stressed anchor cable is arranged; 4, an impact platform foundation and a protection file foundation are poured; 5, sleeve compacting reinforcement is carried out; 6, a connecting part is arranged; 7, pre-tightening anchoring is carried out. The process is easy to construct, safe, reliable, high in connecting strength and good in protection performance, a motor train can be effectively prevented from impacting a building in the testing process, personal safety is protected, and tail machine damage is reduced.

Description

technical field [0001] The invention relates to a construction technology of a protective pile, and specifically relates to a construction technology of a special protective pile for an impact test platform of an EMU car body. Background technique [0002] In recent years, due to the advantages of high speed, stability and comfort, bullet trains stand out in railway transportation and have become an important part of railway transportation. During the manufacturing process of bullet trains, multiple impact tests are required to ensure the safety and stability of their operation. The structural design of the crash-resistant train is to set a certain deformation area on a specific part of the car body, or install an energy absorbing device and an anti-climbing device to absorb as much kinetic energy as possible when the train collides, thereby reducing the collision force and preventing the train from crossing. accidents, thereby minimizing casualties. In the impact test, it ...
