Abstract

The invention discloses a realization method of a seamless rail for straddle-type monorail transportation, relates to a rail beam in a straddle-type monorail transportation system and aims at enhancing the smoothness of the rail, reducing the number of straddle-type rail beam telescopic seams and support seats, reducing the abrasion on rubber tires and the engineering manufacture cost and prolonging the service life of vehicles. The seamless rail for the straddle-type monorail transportation is formed in a concatenated continuous beam bridge, concatenated continuous steel bridge or simple support beam bridge mode, or the seamless rail for the straddle-type monorail transportation is formed in a mode of mixing the three modes or any two modes. The continuous beam bridge or the continuous steel bridge is formed by connecting factory prefabricated concrete rail beams onto bridge pier cover beam top surfaces through wet joints by a method of converting simply-supported beams into continuous beams, simply-supported beam bridges are also prefabricated in factories, the adjacent continuous beam bridges, continuous steel bridges and simply-supported beam bridges adopt seamless telescopic seams, seam connecting plates or plate type rubber telescopic seams for connection, and the seamless effect of the straddle-type monorail transportation is realized.

Description

technical field [0001] The invention relates to a straddle type monorail traffic system, in particular, it is suitable for a straddle type monorail traffic system. Background technique [0002] Most of the track beams in the existing straddle monorail transit system are in the form of simply supported beams. Considering the expansion and contraction deformation of the track beams or turnouts when the temperature changes or the foundation settlement, expansion joints are set at both ends of the track beams or turnouts . At present, the maximum span of simply supported PC track beams with equal height of 1.5m is about 24m, so the number of expansion joints on a line is very large, and when the train passes through these expansion joints, it will generate greater impact and vibration, which will affect the life of the vehicle and passenger comfort, increasing the wear and operation and maintenance costs of train rubber tires. [0003] The PC track beam is not only a load-bear...
