Rapid bridge dismantling construction method under traffic keeping condition
The invention provides a construction method for quickly dismantling a bridge under a traffic keeping condition. The construction method comprises the following steps: S1, determining the position of a beam storage site; s2, temporarily closing the second half space, and keeping the first half space in an open traffic state; s3, marking confirmation points of construction are made respectively; s4, a temporary support is installed on one side of the pier in the second half space of the lower side of the to-be-dismantled bridge, and the temporary support is used for bearing the bottom of the to-be-dismantled bridge; s5, the to-be-dismantled bridge is cut off through the first notch and the second notch; s6, the module beam transporting vehicle is moved to the lower portion of the main span structure, and then the main span structure is supported and stressed through an unloading block; s7, the stress state of the supports on the piers on the lower portion of the main span structure is relieved; and S8, the main span structure is carried into the beam storage site and placed on a beam falling frame in the beam storage site. The construction process links are controllable, the construction precision is high, meanwhile, construction is safe, and efficient and stable bridge demolition is guaranteed.
本发明提供一种保通条件下桥梁快速拆除施工方法，包括以下步骤：S1、确定存梁场地的位置；S2、对第二半幅空间进行临时封闭，保持第一半幅空间处于开放交通状态；S3、分别作出施工的标识确认点；S4、在待拆除桥梁下侧的第二半幅空间内桥墩的一侧安装临时支架，利用临时支架对待拆除桥梁的底部进行承托；S5、通过第一切口和第二切口将待拆除桥梁进行切断；S6、将模块运梁车移动至主跨结构的下部，然后通过卸荷块对主跨结构进行支撑受力；S7、解除主跨结构下部的桥墩上的支座的受力状态；S8、将主跨结构搬运至存梁场地内，放置到存梁场地内的落梁架上。本发明施工工艺环节可控，施工精度高，同时施工安全，保证了桥梁拆除的高效稳定。
