Ballast turnout inserting and paving construction method
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.
本发明涉及一种有砟道岔插铺施工方法，依次包括以下步骤：预铺位置的选取、搭建道岔组装平台（8）、道岔整体预铺拼装、天窗时间点内道岔铺换和道岔开通后巡养，在所述道岔整体预铺拼装完成后进行门架式提轨排装置（17）吊装作业及起吊试验施工。本发明通过采用上砟辅车和上砟主车，使挖机挖掘道床的旧石砟通过上砟辅车和上砟主车直接转运到物料车上贮存，从而解决旧石砟在现场堆料并占用现场空间，以及旧石砟二次搬运的技术问题。通过采用带有能够进行上下和左右摆动以及具有伸缩功能的抛带的第二物料车进行邻线先上底砟的一次回填，同线进行二次回填，从而解决现有道岔铺换需要人工和挖机配合的繁琐工序和施工效率低的技术问题。
