Abstract

The invention discloses a rail transit structure. Six fixing holes are symmetrically formed in a first rail plate adjacent to a junction variable-bending point in four adjacent rail plates on any sideof the junction variable-bending point; six fixing holes are symmetrically formed in the second rail plate adjacent to the first rail plate; four fixing holes are symmetrically formed in the third rail plate adjacent to the second rail plate; four fixing holes are symmetrically formed in the fourth rail plate adjacent to the third rail plate; four fixing holes are symmetrically formed in the N rail plates sequentially connected with the end, away from the target position, of the fourth rail plate, and N is larger than or equal to 1. The fixing holes penetrate through the rail plate and the mortar layer and extend to the supporting layer. And the chemical anchor bolts are arranged in the fixing holes. According to the rail transit structure, the safety of a train can be ensured.

Description

technical field [0001] The application relates to the field of ballastless track, in particular to a rail transit structure. Background technique [0002] At present, the operating mileage of China's high-speed railways has reached more than 29,000 kilometers, more than two-thirds of the total mileage of high-speed railways in the world. my country has become the country with the longest high-speed railway mileage and the highest transportation density in the world. The longitudinally connected slab track structure is one of the main structural forms used in domestic high-speed railway lines with a design speed of 350km / h. The total mileage of the main line is 4852km, accounting for about 30% of the total mileage of high-speed railways without tracks. [0003] The safety, stability and long-term durability of the longitudinally connected slab track structure are greatly affected by factors such as the connection state of the inter-slab joints at the end of the track slab, th...
