The invention discloses a ballastless track renovation method. The method comprises the following steps: measuring a ballastless track to determine a to-be-renovated area and to-be-renovated parameters; chiseling a roadbed slab between two adjacent original track bearing tables of the to-be-renovated area to a preset depth so as to form a pouring position of a new track bearing table; implanting bearing platform reinforcing steel bars in the pouring position of the new track bearing table; according to the to-be-renovated parameters, installing a formwork at the pouring position of the new track bearing table, and forming the new trackbearing table through pouring; after the strength of the new track bearing table meets the requirement, dismantling the formwork, and installing a new fastener on the new track bearing table; and dismantling the original fastener, falling to the new track bearing table, and fastening the new fastener. According to the ballastless track renovation method, the roadbed slab is chiseled away from the to-be-renovated area to form the pouring position of the new track bearing table, the bearing platform steel bars are implanted, and the new track bearing table is formed through pouring so that the renovating process of the ballastless track is simplified, the construction difficulty is reduced, and the renovating construction time is shortened.
Description
technical field [0001] The present application relates to the technical field of disease remediation of railway ballastless track structures, and in particular, relates to a method for remediation of ballastless tracks. Background technique [0002] In recent years, with the rapid development of high-speed railways, my country has built large-scale high-speed railways, which has brought great convenience to people's travel. Ballastless track has the characteristics of good rigidity uniformity, strong structural durability, and small maintenance workload. Therefore, ballastless track is usually used for railways with a design speed of 300 kilometers per hour and tunnels with a length of more than 1 kilometer. [0003] However, the complex geological conditions and huge differences in the natural environment along the high-speed railway make the subgrade often face various unfavorable factors. There is an upturn on the track. In the prior art, a wire saw is usually used to c...
