The invention provides an overline protection structure suitable for a highway bridge broadening reconstruction project, and relates to the technical field of highway bridges. The overline protection structure includes a fixing rod body; the left end and the right end of the fixing rod body are each provided with a fixing clamping base, and a reinforcing support is installed at the rear end of the fixing rod body. A protective frame is mounted between the two fixed rod bodies, and a protective plate is mounted at the outer end of the protective frame; the protection frame isconvenient to disassemble and assemble, meanwhile, the adjacent protection frames are convenient to combine and install, it can be avoided that garbage is accumulated at the bottom of the device, normal running of vehicles is affected, and it can be avoided that stones and the like affect the construction process of a broadened bridge floor of a highway bridge; by arranging a protection plate, the resistance of the outer end of the overline protection structure to object impact pressure is effectively buffered, the overall compressive strength of the overline protection structure is improved, the overall safety coefficient of the overline protection structure is further improved, the compressive strength of the overline protection structure and the supporting performance of the overall overline protection structure are further improved through the reinforcing support, and outward toppling of the overline protection structure due to large internal pressure is avoided.
本发明提供一种适应于公路桥梁扩宽改造工程跨线防护结构，涉及公路桥梁技术领域，包括固定杆体；所述固定杆体左右端各设有固定卡座，固定杆体的后端安装有一处加强支座；两处所述固定杆体之间安装有一处防护架，防护架的外端安装有防护板；本发明的防护架方便拆卸与安装，同时相邻防护架之间便于组合安装，且能够避免垃圾在装置底部堆积，影响车辆的正常行驶，且能够避免石子等影响公路桥梁扩宽桥面的施工过程，防护板的设置有效的缓冲了本装置外端对物体撞击压力的抵抗能力，提高了本装置整体的抗压强度，进一步提高了装置整体的安全系数，加强支座进一步提高了本装置的抗压强度以及整体装置的支撑性，避免了因为较大的内压力而使装置外倾倒。
