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

A transitional structure for turnout and non-turnout zones on low-set, mid-to-low speed magnetic levitation lines comprises non-turnout zone reinforced concrete raft slabs (1), turnout zone reinforced concrete raft slabs (2), reinforced concrete turnout beam foundations (3), multiple rigid pile composite foundations (4), multiple reinforced concrete bored piles (5), non-turnout zone track-bearing beams (6), boss blocks (7), non-turnout zone track-bearing beam lapping platforms (8), trapezoidal filling bodies (9) under the non-turnout zone track-bearing beams, a roadbed (10) under the track-bearing beams (15) in the low-set tracks, roadbed ballast (15) on the outside of the non-turnout zone track-bearing beams. The structure can ensure that the turnout beams do not experience excessive deformation during the turning process due to insufficient rigidity of the foundations, and satisfies the requirements of foundation strength and stability.
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 ...
