Cast-in-place layer steel bar anchoring type small box girder prefabricated anti-collision guardrail and construction method
The invention discloses a cast-in-place layer steel bar anchoring type small box girder prefabricated anti-collision guardrail and a construction method, and relates to the technical field of traffic safety protection.The construction method comprises the following steps that a concrete wall internally provided with an embedded part and a longitudinal connecting piece is prefabricated; an anchoring part is arranged in the bridge foundation, and the anchoring part penetrates through a to-be-poured area above the bridge foundation; a plurality of concrete walls are hoisted to the bridge foundation; the embedded parts of the concrete wall and the corresponding anchoring parts are connected in the to-be-poured area; the multiple concrete walls are connected into a whole in the extending direction of the bridge through longitudinal connecting pieces; and pouring is conducted in the to-be-poured area, so that a bridge deck cast-in-place layer and a pavement layer are formed above the bridge foundation. According to the technical scheme, connection and positioning between the concrete wall and the bridge foundation can be achieved, the positioning strength is guaranteed, meanwhile, the connection convenience between the concrete wall and the bridge foundation is improved, secondary formwork erecting is not needed, and therefore the construction difficulty is reduced.
本发明公开了一种现浇层钢筋锚固式小箱梁预制防撞护栏和施工方法，涉及交通安全防护技术领域，其中，该施工方法包括以下步骤：预制内设有预埋件和纵向连接件的混凝土墙体；在桥梁基础内部设置锚固件，锚固件穿过桥梁基础上方的待浇筑区域；将多个混凝土墙体吊装至桥梁基础上；将混凝土墙体的预埋件与对应的锚固件在待浇筑区域内完成连接；将多个混凝土墙体通过纵向连接件沿桥梁延伸方向连接为整体；在待浇筑区域内进行浇筑，以在桥梁基础上方形成桥面现浇层和铺装层。本发明提供的技术方案能实现混凝土墙体与桥梁基础之间的衔接定位，在保证定位强度的同时提升了混凝土墙体与桥梁基础之间的连接便捷性，无需进行二次支模，从而降低了施工难度。
