Collision test wall and prefabrication and installation method thereof

Abstract

The invention discloses a collision test wall and a prefabrication and installation method thereof, and belongs to the field of collision test field wall construction. The collision test wall comprises a concrete wall body unit which is vertically fixed on the ground, one surface of the concrete wall body unit is provided with anchor bolts which are used for being connected with a nanometer energy absorption safety protection device, the other surface of the concrete wall body unit is provided with a supporting steel reinforcement framework which is used for being connected with the ground, the supporting steel reinforcement framework is fixed to the concrete wall unit through connecting bolts, and the concrete wall unit keeps the vertical fixing state of the concrete wall unit and the ground through the supporting steel reinforcement framework. The collision test wall can be efficiently manufactured on a large scale through a factory prefabrication and installation method, the structure is reasonable, assembly and transportation are convenient, the installation method is easy to operate, the collision test wall can be used repeatedly for different test road sections such as linear sections or curve sections, and the engineering efficiency is high.

Description

technical field [0001] The invention belongs to the field of wall construction in a collision test field, and relates to a collision test wall and a prefabricated installation method thereof. Background technique [0002] The nano-energy-absorbing safety protection device is a safety protection device applied to the inclined roadway walls and tunnel walls of special mines with complex driving conditions. Before the device is used, a crash protection performance test is required. Usually, the nano energy-absorbing safety protection device is fixed on the crash test wall through a screw. [0003] The crash test wall is a temporary building structure, which is designed and formed according to the specified position, and can bear its own weight and external loads acting on it. In the existing nano-energy-absorbing safety protection device impact test wall construction technology, the impact test wall is completed by pre-embedding anchor screws and adopting a construction method...

AI Technical Summary

Problems solved by technology

In this process, the nano energy-absorbing safety protection device can be fixed and installed according to the pre-embedded anchor screw, but the impact test wall is under the load under the specified limit state, and the stability is poor; at the same time, the cast-in-place technology is used, which is inconvenient for construction. For the test scenarios of different road sections, the reusability is poor; and it consumes a lot of manpower and material resources, and the construction cost is high
