Steel spring floating slab ballast bed construction method
The invention relates to the technical field of tunnel construction, and particularly relates to a steel spring floating slab ballast bed construction method. The method comprises the stpes of 1, marks are arranged at equal intervals along the length direction of a tunnel; a floating slab center pile, a floating slab starting point pile, a floating slab terminal point pile and a floating slab expansion joint position pile are arranged; 2, the base steel bars are machined and formed and then transported to a tunnel discharging opening; lifting and placing into tunnel, laying of a foundation reinforcement cage is completed; 3, an expansion joint pouring template is arranged in the length direction of the tunnel; 4, concrete is loaded through a self-orbital-changing concrete construction vehicle and transported into the tunnel, the self-orbital-changing concrete construction vehicle walks on pipe pieces of the circular tunnel and conducts concrete pouring at the same time, and 5, tampingis conducted through a tamping rod, so that the concrete is dense and free of holes. Mutual interference and restriction caused by simultaneous cross construction of the base and the ballast bed are avoided, potential safety hazards are reduced, meanwhile, the construction efficiency is improved, material consumption is reduced, and the ballast bed construction quality is guaranteed.
本发明涉及隧道施工技术领域，具体涉及一种钢弹簧浮置板道床施工方法，包括1沿隧道长度等间距设置基标，并安设浮置板中心桩、浮置板起点桩、浮置板终点桩、浮置板伸缩缝位置桩，2基底钢筋加工成型后运输至隧道下料口，吊放至隧道内，并完成基底钢筋笼的铺设，3沿隧道长度方向设置伸缩缝浇筑模板，在基底中央设置中心水沟模板，4通过自变轨道混凝土施工车装载混凝土运输至隧道内，自变轨道混凝土施工车在圆形隧道的管片上行走，同时进行混凝土浇筑，5利用捣固棒进行捣固，使混凝土密实无空洞。避免了基底和道床同时交叉施工时引起的相互干扰和制约，减少了安全隐患，同时提高了施工效率，减少了材料消耗，保证了道床施工质量。
