The invention relates to the field of high-speed rail tunnel detection equipment, in particular to an assembling system and an assembling method of a horizontal vacuum tunnel detection model. The objective of the invention is to solve the problem of high segment installation difficulty in horizontal vacuum tunnel detection equipment in the prior art. The segment limiting device comprises a regular polygonal segment installation support, each side length forms an independent segment limiting unit, connecting original parts are arranged between the side lengths, and each segment limiting unit comprises support structural steel and a hydraulic supporting mechanism installed on the support structural steel. The other end of the hydraulic supporting mechanism is provided with a patch which is consistent with the outer wall of the duct piece in size, shape and position; a supporting frame and a sliding rail for installing a supporting table are further arranged at the bottom of the installation support, and a lifting mechanism matched with the top segment is arranged on the supporting table. The device has the advantages that the pipe pieces can be used for simulating the vacuum tunnel to be quickly and accurately mounted, and the formed simulated pipeline is good in sealing performance.
Description
technical field [0001] The invention relates to the field of high-speed rail tunnel detection equipment, in particular to an assembly system and method for a horizontal vacuum tunnel detection model. Background technique [0002] For high-speed vehicles operating in the dense atmosphere on the surface, the maximum economic speed should not exceed 400 km / h. The basic principle of the vacuum pipeline system is to establish a closed pipeline, use air extraction equipment to reduce the pressure inside the pipeline, create an operating environment with low medium density, and reduce the aerodynamic resistance of the train, so the running speed of the train has been greatly improved. It is conservatively estimated that the target speed can reach 600~1000km / h, and the later target speed will exceed 4000km / h. The construction of the vacuum pipeline transportation system with the help of the existing rail transit system can save rare ground land resources and make efficient use of t...
