A kind of ballasted turnout inserting construction method

Abstract

The invention relates to a ballasted turnout insertion construction method, which comprises the following steps in sequence: selection of pre-laying positions, construction of a turnout assembly platform (8), overall pre-laying and assembly of turnouts, replacement of turnouts within the time point of the skylight, and inspection after turnouts are opened. After the overall pre-laying and assembling of the turnout is completed, the hoisting operation and hoisting test construction of the gantry type rail lifting device (17) are carried out. In the present invention, by adopting the ballasting auxiliary vehicle and the main ballast vehicle, the old stone ballast excavated by the excavator is directly transferred to the material vehicle for storage through the ballast auxiliary vehicle and the ballast main vehicle, thereby solving the problem of on-site stacking of old stone ballast And occupy the site space, as well as the technical problems of the secondary handling of old stone ballast. By using the second material vehicle with a throwing belt that can swing up and down and left and right and has a telescopic function, the primary backfilling of the bottom ballast on the adjacent line is performed first, and the secondary backfilling is performed on the same line, thereby solving the need for manual and labor-intensive replacement of existing turnouts. The cumbersome process of excavator coordination and the technical problems of low construction efficiency.

Description

technical field [0001] The invention relates to a railway track construction method, in particular to a ballasted turnout insertion construction method. Background technique [0002] At present, the domestic No. 42 ballasted turnout insertion method is still dominated by the traditional manual method. Before the blockage time, build a turnout assembly platform near the turnout laying position to pre-pave the turnout parts, and use small mechanical equipment such as track lifters, slide rails, and rollers for inserting during the blockage time. This technical solution has the following technical defects: On the one hand, due to the use of small mechanical equipment plus purely manual construction methods, it is necessary to carry out long-distance longitudinal movement and multiple lateral movements of small mechanical equipment During the process, the small pulley assembly was disassembled and assembled many times, and sometimes the equipment fell off the track, which incre...

Problems solved by technology

[0006] In order to solve the problems existing in the existing P60-1 / 42 ballasted high-speed turnout existing line insertion construction method, existing railway station reformation and closure point in the whole set of turnout replacement construction technology, ballasted track passenger dedicated line turnout in-situ laying method. However, the present invention provides a ballasted turnout insertion construction method, which is used to solve the above-mentioned technical problems existing in the prior art, and is suitable for the needs of newly built lines and existing line turnouts.
