A test platform and method for the protection capability of a tunnel construction rescue cabin

Abstract

The invention belongs to the matching technical field of tunnel construction rescue and discloses a platform and method for testing the protective capability of a tunnel construction rescue capsule body. The testing platform comprises a bearing stand, a traction device, multiple vertical loading executing mechanisms, and multiple horizontal loading execution mechanisms. The traction device comprises a traction trestle, two winches, a steel wire, and a traction vehicle. The bearing stand is provided with a stopping block. Each vertical loading executing mechanism comprises a vertical hydraulic cylinder and a vertical pressure block. The hydraulic rod of the vertical hydraulic cylinder is disposed vertically. The multiple horizontal loading execution mechanisms are arranged in a left row and a right row. The testing method comprises performing a test for simulating uniformly distributed dead load, a test for simulating impulse load, and a test for simulating local and single-side bias load on the rescue capsule body and the whole rescue capsule. The bearing stand, as the main force-bearing member of the platform, bears the reactive force of loaded static force in a test and may well disperse the reactive force of the loaded static force in the test.

Description

technical field [0001] The invention belongs to the field of static hydraulic loading test devices, and more specifically relates to a test platform and method for the protection ability of a tunnel construction rescue cabin cabin. Background technique [0002] The bearing capacity of the cabin structure of the tunnel construction rescue cabin is an important technical content in the development of the tunnel construction rescue cabin, and is a key indicator of the structural stability of the tunnel construction rescue cabin cabin. Since the tunnel construction rescue cabin test device test object (tunnel construction Due to the particularity of the rescue cabin cabin structure), there is no tunnel construction rescue cabin test device specially designed for it in the relevant fields, and it cannot be adapted to the tunnel construction rescue cabin cabin structure characteristics and test methods. Correspondingly, there is an urgent need for further research and design in th...
