Strengthening construction method for railway switch area line
The invention relates to a strengthening construction method for a railway switch area line. The method comprises the following steps of dividing a construction area into sub areas and separately strengthening the sub areas when the scale of a switch area is large; supporting the sleeper bottom of an existing concrete sleeper by using I-steel transverse beams, arranging two I-steel longitudinal beams on the two sides of each track, locally strengthening a switch and connecting the I-steel transverse beams with the I-steel longitudinal beams through sleeves in the sub areas so that the two sub areas form a whole body; strengthening the area close to a precast frame bridge first; jacking the strengthened frame bridge; and strengthening the rest sub areas before the front edge of the bridge is jacked into the sub areas. The strengthening construction method for the railway switch area line, provided by the invention, is advantaged in that a difficulty problem that a complicated railway switch area line is hard to strengthen is solved; the frame bridge can be accurately jacked in place on the premise that running safety and line safety are assured; the integrity of a line strengthening system is guaranteed; the safety and stability of the railway switch area line are strong; the strengthening construction cost is low; the strengthening operation process is simple; the number of used machines and equipment is less; and the strengthening construction progress is fast.
