Method for reinforcing hollow plate girder bridge by adopting corrugated steel plates and UHPC
The invention relates to the technical field of bridge reinforcement, in particular to a method for reinforcing a hollow plate girder bridge by adopting corrugated steel plates and UHPC, which is characterized by comprising the following steps: treating the concrete surface of an original hollow plate girder bridge bottom plate (1), removing an original steel bar protective layer, and exposing steel bars (5) of an original structure; a corrugated steel plate (3) is prepared, welding studs (4) are arranged on the corrugated steel plate (3), the welding studs and reinforcing steel bars (5) of anoriginal structure are welded together, and then UHPC (2) is poured, so that the corrugated steel plate (3) and a hollow plate girder bridge bottom plate (1) are formed into a whole. The advantages of the corrugated steel plates (3) and the UHPC (2) are fully utilized and combined to be well used for reinforcing the hollow plate girder bridge, so that the hollow plate girder can better work cooperatively, the transverse integrity of the hollow plate girder bridge is enhanced, the service life of the hollow plate girder bridge is prolonged, the bearing capacity of the existing hollow plate girder bridge is enhanced, and the hollow plate girder bridge has wide application prospects.
本发明涉及桥梁加固技术领域，具体涉及一种采用波折钢板及UHPC加固空心板梁桥的方法，其特征在于：对原空心板梁桥底板(1)的混凝土表面进行处理，将原有钢筋保护层清除，露出原结构的钢筋(5)；准备波折钢板(3)，在波折钢板(3)上设置焊钉(4)，将焊钉与原结构的钢筋(5)焊接在一起，然后浇筑UHPC(2)，使波折钢板(3)与空心板梁桥底板(1)形成一体。本发明充分利用波折钢板(3)与UHPC(2)的优势，二者结合可以很好的利用在空心板梁桥的加固上，使空心板梁能更好的协同工作，增强空心板梁桥的横向整体性，提高空心板梁桥的使用寿命，增强既有空心板梁桥的承载能力，具有广泛的应用前景。
