Cofferdam-based tied-arch bridge dismantling structure and bridge dismantling method
The invention relates to the technical field of bridge construction, in particular to a cofferdam-based tied-arch bridge dismantling structure and a bridge dismantling method. The cofferdam-based tied-arch bridge dismantling structure comprises an enclosure structure and a dismantling support. Cofferdams are arranged on the two sides, corresponding to an arch bridge, of the upstream and downstream of a river channel, one ends of the cofferdams are enclosed, and the other ends of the cofferdams are correspondingly connected with the river bank to form an enclosure structure; the dismantling support comprises more than one temporary supporting pier arranged in the direction of a bridge body, each temporary supporting pier comprises a pair of steel pipe pile sets, and each pair of steel pipe pile sets are symmetrically arranged in the transverse direction of the arch bridge; and each steel pipe pile set comprises two or more vertically-arranged steel pipe piles, and the two or more vertically-arranged steel pipe piles are symmetrically arranged on the two sides of a corresponding arch bridge longitudinal beam. Therefore, in the bridge dismantling method, many constructions are carried out on the preset enclosure structure ground, erecting of a support in water is avoided, a construction platform for erecting the support and the like is provided for new bridge construction after an old bridge is dismantled, the construction safety is guaranteed, and the dismantling efficiency is improved.
本发明涉及桥梁施工的技术领域，具体涉及一种基于围堰的系杆拱桥拆除结构及拆桥方法。包括围护结构和拆除支架；河道的上、下游对应拱桥的两侧设有围堰，围堰的一端围合，围堰的另一端和河岸对应连接，形成围护结构；拆除支架包括沿着桥身方向布置的个以上的临时支撑墩，每个临时支撑墩包括一对钢管桩组，每对钢管桩组对称布置在拱桥横向；每个钢管桩组包括两个以上竖直布置的钢管桩，且两个以上竖直布置的钢管桩对称布置在对应拱桥纵梁的两侧。因此本发明拆桥方法中很多施工都在预先设置的围护结构地面上进行，不仅避免在水中架设支架，也为老桥拆除后的新桥建设提供了支架架设等的施工平台，保证施工的安全性，提高拆除效率。
