Description
Technical field
Line area is put the invention belongs to medium-and low-speed maglev traffic engineering is low, more particularly, to a kind of medium-and low-speed maglev
It is low to put circuit rib post distributing track switch foundation structure.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, and current achievement in research both domestic and external is less, entirely
The circuit that the world opens operation is even more a small number of.Only in March, 2005, Japan built the middle low speed magnetic suspension railway business opened at present
The middle low speed magnetic suspension railway business operating line that industry runs line-the East Hillside Line and in June, 2014, South Korea opened.And in China
Low speed magnetic suspension traffic only has National University of Defense technology's test wire, Green City Mountain test wire, Tangshan experiment line at present, but without input fortune
Battalion, and based on elevated structure, rarely seen research and application about rolling stock section's switch area basis.
In wheel rail high speed railway, train lane change is realized by switch machine in rolling stock section, and train passes through Shi Dui roads at a high speed
The impact of trouble is larger, track switch is arranged in soil rigidity relatively uniform position during design and track switch is rushed with reducing as far as possible
Hit, so as to reduce maintenance.It is different from wheel track railway switch, the middle low speed magnetic suspension side of embracing rail operation special due to taking
Formula, magnetic-levitation train lane change is real by the low circuit support rail beam drop-over of putting connected after turnout junction girder unitary rotation certain angle and with it
It is existing.Compared to wheel rail railway, turnout junction girder, which is realized, rotates the fundamental importance that the complicated loads such as pressure, drawing, curved, torsion are undertaken to it more
Height, turnout junction girder rotate easily make turnout junction girder infrastructure produce inhomogeneous deformation, when serious influence magnetic-levitation train comfortableness and
