Connecting method for waterproof settlement joint at junction of new box culvert and old box culvert
The invention discloses a connecting method for a waterproof settlement joint at the junction of a new box culvert and an old box culvert, the connecting method is applied to connecting an old box culvert channel with a new box culvert, and embedded steel bars are arranged in the old box culvert through chiseling; the end of the new box culvert is arranged to be of a protruding structure, newly-built reinforced concrete ring walls are arranged at the protruding position of the new box culvert and the scabbled position of the old box culvert through embedded steel bars, a settlement joint is formed between the two newly-built reinforced concrete ring walls, framework steel bars are bound between the two newly-built reinforced concrete ring walls, and a middle-buried type rubber water stop belt and a foam board of the settlement joint are arranged in the framework steel bars. A gap is reserved between the two newly-built reinforced concrete ring walls, the newly-built reinforced concrete ring walls are subjected to concrete pouring and maintenance, and the old box culvert is subjected to chiseling and rebar planting treatment, so that the newly-poured reinforced concrete ring walls and the old box culvert are firmly engaged to form a stress whole. The reinforced concrete ring wall is arranged on the periphery of the old box culvert, and the ring wall is arranged at the end of the new box culvert in a protruding mode, so that connection of the new box culvert and the old box culvert can be effectively converted into connection of the new box culverts.
本发明公开了一种新旧箱涵交接处防水沉降缝的连接方法，该连接方法应用于旧箱涵通道连接新箱涵，通过在旧箱涵凿毛设置有植筋；并将新箱涵的端头设为为凸起结构，且新箱涵的凸起处和旧箱涵的凿毛处通过植筋均设置有新建钢筋砼圈墙，两个新建钢筋砼圈墙之间形成沉降缝并绑扎有骨架钢筋，骨架钢筋内设置有中埋式橡胶止水带和沉降缝的泡沫板，两个新建钢筋砼圈墙之间留有间隙，新建钢筋砼圈墙通过浇筑混凝土并养护，对旧箱涵进行凿毛并植筋处理，使得新浇筑的钢筋砼圈墙与旧箱涵牢牢的咬合成一个受力整体。通过在旧箱涵外围设置钢筋砼圈墙，在新箱涵端头凸起设置圈墙，可有效的将新、旧箱涵交接转变为新箱涵与新箱涵的交接。
