The invention relates to the technical building field of railways and relates to a D-shaped auxiliary girder overhead reinforced line turnout zone system. The D-shaped auxiliary girder overhead reinforced line turnout zone system comprises a D-shaped auxiliary girder; the D-shaped auxiliary girder extends to be arranged in a turnout zone; the D-shaped auxiliary girder comprises two pieces of longitudinal girders and one line of cross girders, wherein the two pieces of longitudinal girders are placed in parallel, and the line of cross girders is erected between the two pieces of longitudinal girders; and the distance between the two adjacent cross girders close to a turnout point position is less than 670 mm. Buckling plate locating supports are arranged in positions, on the top surfaces ofthe cross girders, on the D-shaped auxiliary girder; the buckling plate locating supports are arranged on the two sides of each steel rail in the turnout zone; buckling plates are configured on the buckling plate locating supports; the buckling plate locating supports and the buckling plates are fixed on the D-shaped auxiliary girder through bolts; and the buckling plate locating supports and thebuckling plates are used for fixing the position of the D-shaped auxiliary girder and the position of the steel rail of the turnout zone. According to the D-shaped auxiliary girder overhead reinforced line turnout zone system, by adopting the D-shaped auxiliary girder with the more closely arranged cross girders and reinforcing the D-shaped auxiliary girder, the problem of wasting time and laborcaused by longitudinal and transverse I-shaped steels is eliminated, rapid construction can be realized, and the integrity of the reinforced line is good.
Description
technical field [0001] The invention relates to the technical construction field of railways, in particular to a D-shaped beam overhead reinforcement line turnout area system. Background technique [0002] At present, in railway lines, vertical and horizontal I-steel beam lifting method is commonly used to strengthen turnouts. Due to the influence of components such as tongue rails, sleepers, and sliding bed plates, the installation is extremely complicated, and it consumes a lot of steel, labor and time. There are many bolts and poor rigidity. , It is easy to cause line deformation and cause traffic accidents. Contents of the invention [0003] The purpose of the present invention is to provide a D-type convenient beam overhead reinforcement line turnout area system, which adopts D-type convenient beams with encrypted beams and reinforces them, so as to improve the labor-intensive and time-consuming problems caused by the use of vertical and horizontal I-beams, and can qu...
