Connection construction method for connection position of widened bridge
The invention relates to a connection construction method for a connection position of a widened bridge, the widened bridge comprises a new bridge and an existing bridge, a connecting seam is arranged between the new bridge and the existing bridge, and the bridge surface of the new bridge and the bridge surface of the existing bridge are located on the same plane; the connecting construction method comprises the following steps that grooves are formed in the sides, facing the connecting seam, of the new bridge and the existing bridge in a chiseling mode; a reinforcing assembly is installed in each groove; steel fiber reinforced concrete is poured into each groove; after the steel fiber reinforced concrete reaches the preset strength, the connecting seam is filled with mastic asphalt. On one hand, the steel fiber reinforced concrete is adopted, and the connecting seam is filled with mastic asphalt, so that the integrity of the widened bridge is improved; meanwhile, the driving safety is improved; on the other hand, the method is simple in construction, short in construction period and low in manufacturing cost.
本发明涉及一种加宽桥梁连接处连接施工方法，加宽桥梁包括新桥梁以及现有桥梁，新桥梁与现有桥梁之间设有连接缝，且新桥梁的桥面与现有桥梁的桥面位于同一平面；连接施工方法包括如下步骤：新桥梁与现有桥梁朝向连接缝的一侧均凿设有沟槽；在每个沟槽内均安装加强组件；向每个沟槽内均浇筑钢纤维混凝土；钢纤维混凝土达到预设强度后，向连接缝填充沥青马蹄脂；一方面，通过采用钢纤维混凝土，且在连接缝处填充沥青马蹄脂，由此，提高了加宽桥的整体性；同时，提高了行车的安全性；另一方面，该方法施工简单、施工周期短、造价低。
