Half-excavated and half-filled stone roadbed structure and construction method
The invention provides a half-excavated and half-filled stone roadbed structure and a construction method, a plurality of steps are arranged on the filling side of a roadbed, rectangular concrete precast blocks are fully paved on each step, the outer side surface of the precast block on the upper step is flush with the outer side surface of the precast block on the lower step, and the top surface of the precast block on the uppermost step is flush with the top surface of the roadbed on the excavation side; at least two anchor rods transversely penetrate through each precast block along the roadbed, one end of each anchor rod extends into a mountain body on the excavation side, and the other end of each anchor rod is anchored on the outer side of the corresponding precast block. The precast blocks are anchored through anchoring force provided by the mountain, the rigid roadbed is formed, pavement construction can be conducted without rolling compaction, the construction speed is high, the cost is low, the roadbed structure is stable, and the half-excavated and half-filled stone roadbed structure is particularly suitable for excavation and filling roadbed construction with the small filling amount.
本发明提供一种半挖半填石质路基结构及施工方法，路基填方侧设有多级台阶，每级台阶上满铺矩形的混凝土预制块，上级台阶上的预制块外侧面与下级台阶上的预制块外侧面齐平，最上一级台阶上的预制块顶面与挖方侧路基顶面齐平，每个预制块沿路基横向穿设至少两根锚杆，锚杆一端深入到挖方侧的山体内，另一端锚固在预制块的外侧。本发明利用山体提供锚固力将预制块锚固，形成刚性路基，无需进行碾压即可进行路面施工，施工速度快，费用低，路基结构稳定，尤其适用于填方量不大的办挖办填路基施工。
