Rapid construction method for elastic supporting block type monolithic track bed
The invention discloses a rapid construction method for an elastic supporting block type monolithic track bed, and relates to the field of construction of monolithic track beds in tunnels. After construction preparation, transporting and placing steel bars and supporting blocks, then surveying and setting out, roughening a bottom plate, and planting the steel bars; laying and binding lower-layer reinforcing steel bars, and placing upper-layer reinforcing steel bars; assembling, hoisting and roughly adjusting the track panel; binding upper-layer reinforcing steel bars; mounting a template; mounting expansion joint plates; finely adjusting and fixing the track panel; then carrying out insulation performance test, ballast bed concrete pouring, tamping, surface finishing and curing; and finally, dismounting the track bent frame, and dismounting the support and the template. Gantry crane construction is conducted, and limited space is reasonably utilized for construction of all procedures;the movable assembling platform solves the problem that the assembling distances of the supporting blocks are unequal; the supporting block hoisting device improves the hoisting efficiency and accelerates the track panel assembling speed; the expansion joint steel plate ensures the straightness of the expansion joint; a surface finishing tool solves the problem of the gradient of a concrete surface. According to the construction method, the construction procedures are scientifically arranged, connection is tight, and the construction quality is guaranteed.
本发明公开了一种弹性支承块式整体道床快速施工工法，涉及隧道中整体道床的施工领域。施工准备后进行钢筋、支承块运输及摆放，然后测量放线，底板凿毛、植筋；铺设绑扎下层钢筋、摆放上层钢筋；轨排组装、吊装、粗调；上层钢筋绑扎；安装模板；伸缩缝板安装；然后精调并固定轨排；之后进行绝缘性能测试、道床混凝土浇筑、捣固、收面和养生；最后拆除轨道排架、拆除支撑及模板。龙门吊施工，合理利用有限空间进行各工序施工；移动组装平台解决了支承块组装间距不等的问题；支承块吊装装置提高了吊装效率，加快了轨排组装速度；伸缩缝钢板保证了伸缩缝的顺直；收面工装，解决了混凝土面坡度的问题。本发明所提供的施工工法，科学安排施工工序，衔接紧密，保证施工质量。
