Dismantling method suitable for middle-pier-free overpass bridge
The invention relates to the technical field of construction management, in particular to a dismantling method suitable for an overpass bridge without a middle pier. Comprising the following steps: S1, traffic guidance and modification are carried out on a bridge to be dismantled; s2, temporary buttresses are mounted at the bottom of the to-be-disassembled bridge; s3, safety protection fences for bridge disassembly construction are installed on the two sides of the to-be-disassembled bridge; s4, a beam body of the to-be-dismantled bridge is cut through a rope saw; s5, monitoring and measuring points capable of monitoring the stress condition of the bridge are arranged on the bridge to be dismantled; s6, framing dismantling is conducted on the to-be-dismantled bridge; and S7, after the to-be-dismantled bridge is dismantled, the temporary buttresses and the fences are dismantled, and traffic is recovered. According to the method, the overpass bridge without the middle pier can be dismantled under the condition that road traffic is not affected, and the method is simple and easy to implement, low in construction cost, short in construction period and large in economic benefit.
本发明涉及施工管理技术领域，尤其涉及一种适用于无中墩上跨桥梁的拆除方法。包括以下步骤：S1、在待拆桥梁上进行交通导改；S2、在待拆桥梁底部安装临时支墩；S3、在待拆桥梁两侧安装桥梁拆卸施工用的安全防护围挡；S4、通过绳锯切割待拆桥梁的梁体；S5、在待拆桥梁上布置可以监测桥梁受力情况的监控测量点；S6、对待拆桥梁进行分幅拆除；S7、待拆桥梁完成拆除后，对临时支墩和围挡进行拆除，并恢复交通。该方法不仅能够在不影响道路交通的情况下对无中墩上跨桥梁进行拆除，而且简单易行，施工成本低，工期短，经济效益大。
