Ballast turnout inserting and paving construction method

Abstract

The invention relates to a ballast turnout inserting and paving construction method which sequentially comprises the following steps of selecting a pre-paving position, building a turnout assembling platform (8), integrally pre-paving and assembling turnouts, paving and replacing the turnouts within a skylight time point and maintaining the turnouts after the turnouts are opened, and carrying outhoisting operation and hoisting test construction of a portal type track panel lifting device (17) after the integral pre-paving and assembling of the turnouts are completed. By the adoption of a ballast loading auxiliary vehicle and a ballast loading main vehicle, old stone ballasts of an excavator excavation ballast bed are directly transferred to the material vehicle to be stored through a ballast loading auxiliary vehicle and a ballast loading main vehicle, and therefore the technical problems that the old stone ballasts are stacked on site and occupy the site space, and secondary carryingof the old stone ballasts is conducted are solved. The second material vehicle with the throwing belt capable of swinging up and down and left and right and having the telescopic function is adoptedfor primary backfilling of bottom ballasts on adjacent lines and secondary backfilling of bottom ballasts on the same line, and therefore the technical problems that according to existing turnout laying and replacing, complex procedures of cooperation of manpower and an excavator are needed, and the construction efficiency is low are solved.

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.
