Rib column distributed turnout foundation structure of middle-low speed magnetic levitation low-arranged line

Abstract

The invention discloses a rib column distributed turnout foundation structure for a middle-low speed magnetic levitation low-arranged line. The rib column distributed turnout foundation structure for the middle-low speed magnetic levitation low-arranged line comprises turnout zone foundation treatment reinforced concrete rafts, reinforced concrete turnout beam bar-type rib column foundations, reinforced concrete cast-in place piles, steel plates and embedded bolts. The turnout zone foundation treatment reinforced concrete rafts are arranged horizontally, and the multiple reinforced concrete cast-in place piles are arranged at the bottom end faces of the turnout zone foundation treatment reinforced concrete rafts; the reinforced concrete cast-in place piles penetrate a soft stratum to extend into a bearing stratum, to decrease the deformation of turnout beams in the rotation process. The rib column distributed turnout foundation structure for the middle-low speed magnetic levitation low-arranged line ensures that the turnout beams are not deformed greatly in the rotation process due to inadequate foundation stiffness, and meets the requirements for foundation strength and stability by the turnout beams.

Description

technical field [0001] The invention belongs to the field of low-set lines of medium and low-speed maglev traffic engineering, and more specifically relates to a rib-column decentralized turnout foundation structure of medium-low-speed maglev low-set lines. Background technique [0002] Medium and low-speed maglev rail transit is a new type of transportation. At present, 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 they have not been put into operation, and they are mainly eleva...

Problems solved by technology

Compared with the wheel-rail railway, the turning of the turnout beam has higher requirements on the foundation that bears complex loads such as compression, tension, bending, and torsion. The rotation of the turnout beam is likely to cause uneven deformation of the lower foundation of the turnout beam, which will affect the maglev train in severe cases. comfort and normal lane changes
