Construction method for filling expressway roadbed with tunnel slag
The invention is applicable to the technical field of highway construction, and provides a construction method for filling a highway roadbed with tunnel hole slag, which comprises the following steps: adjusting tunnel blasting slotting holes and auxiliary holes according to preset blasting parameters to ensure the tunnel blasting forming quality and reduce the lumpiness of blasting hole slag, and obtaining hole slag filler through tunnel blasting treatment; the method comprises the following steps: carrying out grading design on hole slag fillers at different filling parts of a roadbed by utilizing a coarse aggregate continuous grading formula process, and carrying out adjustment and optimization treatment on the hole slag fillers in different particle size ranges according to a designed grading curve and a hole slag grading actual measurement curve so as to enable the filler grading to meet preset filling requirements; the method comprises the following steps: carrying out base treatment on an expressway foundation by utilizing hole slag filler, and carrying out reinforcement treatment on the hole slag high-fill roadbed by combining an impact rolling method and a layered staggered dynamic compaction method after paving and leveling treatment and rolling forming treatment. The construction method is simple, remote transportation of the tunnel blasting hole slag is avoided, the resource utilization rate is increased, and the influence on the natural environment is reduced.
本发明适用公路建筑技术领域，提供隧道洞渣填筑高速公路路基施工方法，包括：通过对隧道爆破掏槽孔和辅助孔按照预设爆破参数进行调整以保证隧道爆破成形质量的同时降低爆破洞渣块度，经隧道爆破处理，得洞渣填料；利用粗粒料连续级配方程对路基不同填筑部位的洞渣填料进行级配设计，以根据设计级配曲线与洞渣级配实测曲线，分粒径范围对所述洞渣填料进行调整优化处理以使填料级配满足预设填筑要求；利用洞渣填料对高速公路地基进行基底处理，经摊铺整平处理及碾压成型处理后，采用冲击碾压和分层错位强夯法联合对洞渣高填方路基进行补强处理。本发明施工方法简单，避免了隧道爆破洞渣的远运，不仅提高资源利用率且减小对自然环境的影响。
