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.
