Turnout zone and non-turnout zone transition section structure for medium and low-speed magnetic levitation low implantation line

Abstract

The invention discloses a turnout zone and non-turnout zone transition section structure for a medium and low speed magnetic levitation low implantation line. The transition section structure comprises non-turnout zone reinforced concrete rafts, turnout zone reinforced concrete rafts, reinforced concrete turnout beam strip foundation, composite foundation of a plurality of rigid piles, a plurality of reinforced concrete cast-in-situ bored piles, a non-turnout zone bearing-trail beam, boss stoppers, a non-turnout zone bearing-trail beam overlapping platform, a non-turnout zone bearing-trail beam lower trapezoidal fill body, a low implantation line bearing-trail beam lower foundation and a non-turnout zone bearing-trail beam outside subgrade filling. According to the transition section structure disclosed by the invention, the condition that extremely large deformation of the turnout beam is caused in the rotating process due to insufficient stiffness of the foundation can be avoided, and the requirements of the turnout beam on the basement strength and stability of the foundation are met.

Description

Technical field [0001] The invention belongs to the field of low-position line structure of medium and low-speed maglev traffic engineering, and more specifically relates to a transition section structure of a turnout area and a non-turnout area of ​​a low- and medium-speed maglev line. Background technique [0002] The low-to-medium-speed maglev rail transit is a new type of transportation. At present, there are few research results at home and abroad, and there are only a few lines in operation all over the world. At present, there are only the mid-to-low-speed maglev railway commercial operation line-Eastern Hills Line that was constructed and opened in Japan in March 2005 and the mid-low-speed maglev railway commercial operation line opened in June 2014 in South Korea. At present, China's low- and medium-speed maglev transportation has only the National University of Defense Technology test line, the Qingchengshan test line, and the Tangshan test line, but they have not been ...

AI Technical Summary

Problems solved by technology

Due to the different loads of the turnout beam and the low-mounted line rail-bearing beam, and the low-mounted line rail-bearing beam is built on the filled soil subgrade, uneven settlement between the two is unavoidable; Although the same foundation type is convenient for settlement and stiffness transition, it is often uneconomical
