Problems solved by technology

[0004] At present, the technology to deal with this gap is to replace the track slab, but the implementation cost of this technology is huge, and the construction period is long, resulting in a long time to affect the traffic, and after the replacement is completed, the speed of the train must be limited for a certain period of time

Embodiment Construction

[0036] In this embodiment, the method for adjusting the distance between the track slabs of the high-speed railway CRTS Ⅱ slab ballastless track is carried out in the following steps:

[0037] The first step: if figure 1 As shown, the situation of the separation seam 2 produced by the track slab is measured, and the processing conditions are determined as follows: the track slab 1 appears as a separation track slab due to a single-side separation seam or a horizontal through separation seam, and the arching amount of the separation seam track slab is not less than 2mm; Usually, the amount of camber of the track slab from the seam is not more than 9mm. That is, the amount of camber of the track slab from the seam is 2-9mm.

[0038] The second step: if figure 2 As shown, with the separation track plate 5 as the center track plate, seven track plates are set on the symmetrical sides of the center track plate as anchoring track plates, and the seven track plates are adjacent to...

Abstract

The invention discloses a method for treating a gap of a track slab of a rapid transit railway CRTSII type slab ballastless track. The method is characterized in that determination and treatment are carried out as follows: the track slab is changed into a gapped track slab due to one side gap or a transverse run-through gap, and the length of the upwards cambered part of the gapped track slab is not smaller than 2mm; the gapped track slab is used as a central track slab, seven track slabs are respectively arranged on the symmetrical two sides of the central track slab as anchoring track slabs, the track slabs which are adjacent to the gapped track slab are the first track slabs, and the second to seventh track slabs are sequentially arranged from the first track slabs to the two sides; the second to seventh track slabs are anchored through inserting steel bars; then, wide joint unlocking is realized through chiseling wide joint concrete between the gapped track slab and the first track slabs so as to eliminate the gap, and wide joint concrete is poured again; finally, the first track slabs on the two sides are anchored through inserting steel bars. The method disclosed by the invention can effectively eliminate the gap and provide safety guarantee for the running of rapid transit railway. The construction, organization and operation of the method are convenient and quick.

Description

technical field [0001] The invention relates to the technical field of line maintenance of ballastless track of high-speed railway, and more specifically relates to a method for regulating the distance between track slabs of CRTS II slab-type ballastless track of high-speed railway. Background technique [0002] High-speed railway refers to a railway with a running speed of more than 200 km / h. It is a huge system project that is organically combined with infrastructure suitable for high-speed operation, fixed equipment, mobile equipment, a complete and scientific safety assurance system and transportation organization methods. It is a comprehensive integration of contemporary high-tech. [0003] When the high-speed railway was put into operation, maintenance problems of the high-speed railway ballastless track line followed. Arching occurs on the ballast track track slab, such as figure 1 As shown, a separation gap 2 appears between the track slab 1 and the mortar cushion ...
