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
The invention belongs to that medium-and low-speed maglev traffic engineering is low puts line area, more particularly, to one
Medium-and low-speed maglev is low puts circuit rib post distributing track switch base structure.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, current both domestic and external studies into
The most less, the circuit minority especially of operation is opened in the whole world.The most only in March, 2005, Japan built
Middle low speed magnetic suspension railway comercial operation line-the East Hillside Line of opening and in June, 2014 Korea S open-minded
Middle low speed magnetic suspension railway business operating line.And the middle low speed magnetic suspension traffic of China only has state at present
Anti-University of Science and Technology test wire, Green City Mountain test wire, Tangshan experiment line, but do not put into effect, and all
Based on elevated structure, the rarely seen research about rolling stock section's switch area basis and application.
In wheel rail high speed railway, in rolling stock section, train lane change is realized by switch machine, and train is at a high speed
By time relatively big to the impact of track switch, generally make track switch be arranged in soil rigidity during design relatively uniform
Position is to reduce the impact to track switch as far as possible, thus reduces maintenance.It is different from wheel track railway switch,
Middle low speed magnetic suspension is owing to taking the special mode embracing rail operation, and turnout junction girder is passed through in magnetic-levitation train lane change
The low circuit support rail beam drop-over of putting connected after unitary rotation certain angle and with it realizes.Compared to wheel track
Railway, turnout junction girder realize rotating to its undertake pressure, draw, the basis of the complicated loads such as curved, torsion will
Asking higher, turnout junction girder rotates and easily makes turnout junction girder infrastructure produce inhomogeneous deformation, affects time serious
The comfortableness of magnetic-levitation train and normal lane change.
