Road widening construction method
The invention discloses a road widening construction method, which relates to the technical field of road construction, and specifically comprises the following steps: 1, surveying and setting out, and determining a construction range and an excavation elevation; secondly, sundries on the surface of the roadbed to be widened are cleaned; thirdly, longitudinal steel bars are arranged at the connecting positions of the original roadbed and the widened roadbed; fourthly, a plurality of connecting piles are driven into the inner sides of the longitudinal steel bars at equal intervals, and cement is poured after the rotating pipes are connected; fifthly, the main connector assembly and the auxiliary connector assembly are connected at the bottom of the connecting pile, and then the screwing handle is screwed to enable the clamping anchor to stretch out; sixthly, the connecting position of the original roadbed and the widened roadbed is filled with asphalt concrete, and an asphalt concrete layer is formed. Through the arrangement of the longitudinal steel bars, the connecting piles and the clamping anchor assemblies, the connecting positions of the new road and the old road can be stably connected in the transverse direction, the longitudinal direction and the vertical direction, and the phenomenon that the connecting positions are cracked or cracked due to uneven stress or overlarge stress can be effectively avoided.
本发明公开了一种道路拓宽施工方法，涉及道路施工技术领域，具体包括以下步骤：第一步、测量放线，确定施工范围及开挖标高；第二步、清理待拓宽路基表面的杂物；第三步、在原路基和拓宽路基的连接位置布设纵向钢筋；第四步、在纵向钢筋的内侧打入多个间隔相同的连接桩，使得转管相连后开始灌注水泥；第五步、在连接桩的底部使主连接头组件与副连接头组件相连，然后拧动拧柄，使得卡锚伸出；第六步、在原路基和拓宽路基的连接位置填充沥青混凝土，并形成沥青混凝土层。通过设置的纵向钢筋、连接桩和卡锚组件，能够使新旧道路连接处的横、纵和竖直方向连接稳固，可有效避免连接处发生因受力不均或受力过大而引发的裂缝或崩裂现象。
