Method for dismantling continuous-crossing large-span cast-in-place overbridge on road
The invention discloses a method for dismantling a highway continuous-crossing large-span cast-in-place overbridge, and belongs to the technical field of highway-crossing large-span cast-in-place overbridge dismantling construction. The overbridge comprises a single span or a double span; the dismantling method is used for dismantling a cast-in-place overbridge with the width larger than the total width of an existing road surface of a road, during construction, a traffic diversion method that road traffic is not interrupted and coming and going vehicles normally pass is adopted, temporary cross braces are arranged below beam bodies, the beam bodies are cut and hoisted away, and the temporary cross braces are moved till all the beam bodies are dismantled; the beam body is cut off section by section from one side of a road to the other side, namely, the beam body is cut in the longitudinal direction of the overpass. According to the invention, economic loss and inconvenient passage caused by traffic interruption on a road are avoided; required facilities and equipment are relatively conventional and common, and can be flexibly obtained on site, so that the construction cost is low; the management difficulty of on-site construction organizations is low, the construction thought is simple and easy to understand, management and control in the on-site construction process are facilitated, and safety and reliability can be guaranteed.
一种公路不断交大跨径现浇天桥拆除方法，属于跨公路大跨径现浇天桥拆除施工技术领域。所述天桥包括单跨跨越或双跨跨越；所述拆除方法用于大于公路既有路面总宽度的现浇天桥拆除，在施工期间，采用不中断公路交通，往来车辆正常通行的交通导流方法，在梁体下方设置临时横撑，进行梁体切割吊离，并移动临时横撑，直至全部梁体拆除完成；所述梁体切割顺序为：从公路的一侧向另一侧逐节切除，即沿天桥纵向方向切割。本发明避免公路中断交通造成的经济损失和通行不便；所需设施、设备均较为常规普通，现场可灵活获取，施工成本低；对现场施工组织的管理难度较低，施工思路较为简单、容易理解，方便现场施工过程中的管控，安全可靠性能够得到保障。
