Problems solved by technology

In the low-lying line section, the foundation under the rail-bearing beam is a geotechnical structure composed of rock and soil. Affected by factors such as terrain and geological conditions, the quality is relatively difficult to control. It is prone to uneven settlement under the action of load and various natural environmental factors. It is inevitable that post-construction settlement inconsistent with the bridge abutment of the elevated structure will occur, resulting in poor post-construction settlement. The settlement difference between the low-lying line and the bridge abutment position will inevitably affect the smoothness of the F track, and may even cause the F track to be misplaced. , deformation and other problems, in severe cases, will affect the normal operation of maglev vehicles

Abstract

The invention belongs to the technical field of medium-low speed maglev traffic engineering low-set lines and discloses a medium-low speed maglev traffic engineering double-line filling section pile foundation support beam type rail bearing beam transition section structure. The transition section structure comprises multiple pile foundation bearing structures, a reinforced concrete support beam, reinforced concrete rail bearing beam base plates, two rows of reinforced concrete beam type structures, lower roadbed filler of a rail bearing beam, two-side backfill filler of the rail bearing beam, a bridge abutment, a trapezoid filling body and end walls, wherein the reinforced concrete beam type structures are connected to the top ends of the reinforced concrete rail bearing beam base plates in a supported mode, and the two-side backfill filler of the rail bearing beam is supported by the lower roadbed filler of the rail bearing beam. The transition section structure is higher in long-term stability, the high requirement for rail bearing beam structural deformation and post-construction settlement is met, the requirement for long-term stability, durability and construction quality controllability of a foundation bed is met, and smooth transition between a maglev elevated structure and a low-set line transition section F rail is effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of low-mounted lines of medium and low-speed maglev traffic engineering, and more specifically relates to a structure type of a transition section of a rail-bearing beam in a double-line filling section of a medium-low speed maglev traffic engineering. Background technique [0002] Medium and low-speed maglev rail transit is a new type of transportation. There are few research results at home and abroad, and there are even fewer lines in operation around the world. At present, there are only the commercial operation line of the medium and low speed maglev railway in Japan in March 2005-Eastern Hills Line and the commercial operation line of the medium and low speed maglev railway in South Korea in June 2014. At present, China's medium and low-speed maglev transportation only has the National University of Defense Technology test line, the Qingchengshan test line, and the Tangshan test line, but there are no ...
