Cross-railway framing bridge protection structure and construction method thereof
The invention relates to a cross-railway framing bridge protection structure and a construction method thereof. The method comprises the steps that after a central anti-collision guardrail above a railway influence range is constructed, construction of a cross-railway bridge is conducted in a swivel or pushing mode; and an overline cover plate section is buckled on the central anti-collision guardrail outside the railway influence range, and the overline cover plate section is translated to the upper part of the railway and is fixed on the central anti-collision guardrail. The protection structure comprises two central anti-collision guardrails arranged on the two sides of a middle zoning belt of the bridge respectively and the overline cover plate section located above the railway, and the overline cover plate section is of an inverted-U-shaped structure and can be buckled on the two central anti-collision guardrails in a sliding mode. According to the invention, the hoisting construction of the cover plate above the railway is avoided, and the operation safety of the railway below is ensured; and by the adoption of the protection structure of the central anti-collision guardrailand the cover plate, the situation that objects fall off from a zoning belt in the framing bridge can be effectively prevented, on one hand, safety of railways under the bridge is guaranteed, and on the other hand, safety of vehicles on the bridge is guaranteed.
本发明涉及一种跨铁路分幅桥梁防护结构及其施工方法，方法包括：施作铁路影响范围上方的中央防撞护栏后，采用转体或顶推方式进行跨铁路桥梁的施工；在铁路影响范围之外将跨线盖板节段扣置到中央防撞护栏上，使跨线盖板节段平移至铁路上方并固定在中央防撞护栏上。防护结构包括分列于桥梁中分带两侧的两面中央防撞护栏以及位于铁路上方的跨线盖板节段，跨线盖板节段呈倒U型结构并且可滑动地扣合在两面中央防撞护栏上。本发明避免了在铁路上方进行盖板的吊装施工，保证下方铁路运营安全；采用中央防撞护栏+盖板的防护结构，能有效地防止分幅桥梁中分带出现坠物等情况，一方面保证桥下铁路等的安全，另一方面保证桥上车辆等的安全性。
