Fabricated anti-collision guardrail for bridge engineering and anti-collision method of fabricated anti-collision guardrail
The invention relates to the technical field of bridge construction, in particular to a fabricated anti-collision guardrail for bridge engineering, which comprises a prefabricated anti-collision guardrail and a prefabricated bridge deck slab. A plurality of first buffer grooves are formed in the lower portion of the side, close to the middle of the prefabricated bridge deck slab, of the prefabricated anti-collision guardrail, first limiting rings are arranged in the first buffer grooves, first limiting plates are slidably arranged in the first buffer grooves, and first pull rods penetrating through the first limiting rings are fixed to the sides, close to the first limiting rings, of the first limiting plates; the end, away from the first limiting plate, of the first pull rod is connected with a first inhaul cable, and a first buffer spring is arranged between the first limiting plate and the first limiting ring. First protrusions in one-to-one correspondence with the first buffer grooves are arranged on the top face of the prefabricated bridge deck slab, lifting grooves are formed in the prefabricated bridge deck slab, the first protrusions are arranged at the upper ends of the lifting grooves in an up-down sliding mode, vertical piles are arranged at the bottoms of the first protrusions, and the lower ends of the vertical piles are connected with the bottoms of the lifting grooves through first connecting springs. The end, away from the first pull rod, of the first inhaul cable penetrates through the first channel and is fixedly connected with the vertical pile.
本发明涉及桥梁施工技术领域，涉及一种桥梁工程用装配式防撞护栏，包括预制防撞护栏及预制桥面板。预制防撞护栏靠近预制桥面板中部的一侧下部设有若干第一缓冲槽，第一缓冲槽设置有第一限位环，第一缓冲槽内滑动设有第一限位板，第一限位板靠近第一限位环的一侧固定有穿过第一限位环的第一拉杆，第一拉杆远离第一限位板的一端连接有第一拉索，第一限位板与第一限位环之间设有第一缓冲弹簧。预制桥面板顶面设置有与第一缓冲槽一一对应的第一凸起，预制桥面板上设置有升降槽，第一凸起上下滑动设置于升降槽的上端，第一凸起底部设置有竖桩，竖桩下端通过第一连接弹簧与升降槽底部连接。第一拉索远离第一拉杆的一端穿过第一通道且与竖桩固定连接。
