A line-to-line drainage structure used in the double-line section of the low-lying low-speed magnetic levitation line

Abstract

The invention discloses a line-to-line drainage structure for double-line sections of medium and low speed magnetic suspension lower lines. The line-to-line drainage structure comprises a foundation bed, a line-to-line drainage device, strong current cable support seats and a water guide layer, wherein the foundation bed is arranged on a roadbed; the line-to-line drainage device is arranged in a drainage groove of the foundation bed and comprises a bottom plate, a first vertical wall, a second vertical wall, drainage holes and vertical wall lugs, wherein a plurality of drainage holes are penetrated in the first vertical wall and the second vertical wall; the quantity of the strong current cable support seats is equal to the quantity of the vertical wall lugs; and the water guide layer is arranged on a top end face of the foundation bed and is used for guiding water into a drainage channel of the line-to-line drainage device. The line-to-line drainage structure disclosed by the invention can well adapt to line-to-line drainage and cable laying of magnetic suspension traffic engineering and can ensure long-term stability and durability of the foundation bed.

Description

Technical field [0001] The invention belongs to the field of railway rail transit, and more specifically, relates to an inter-line drainage structure used for a double-line section 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 Hill 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. However, China’s low- and medium-speed maglev transportation currently only has the National University of Defense Technology test line, the Qingchengshan test line, and the Tangshan test line, but there are no official lines put into operation, and they are all based on elevat...
