Half-through net-shaped suspender arch bridge and construction method thereof
The invention discloses a half-through netlike suspender arch bridge which comprises arc-shaped arch ribs located on the two sides of a bridge floor structure, netlike suspenders connecting the arch ribs and the bridge floor structure and on-arch stand columns, a plurality of transverse supports are arranged between the arch ribs, each arch rib is formed by butt joint of hollow steel pipes, and the outer surface of each hollow steel pipe is coated with a CA-UHPC outer covering layer; the CA-UHPC is introduced into the arch ribs of the reticular suspender arch bridge, and the CA-UHPC material and the steel pipes are combined, so that the arch bridge has the characteristics of high spanning capacity, high stress efficiency and rapidness, simplicity and convenience in construction. When the arch bridge is adopted in engineering construction, the common defects that a large-span concrete arch bridge is too large in self weight, a full-steel arch bridge is large in thick steel plate welding difficulty and high in cost, and a CFST arch bridge is adopted can be overcome.
本发明公开了一种中承式网状吊杆拱桥，包括位于桥面结构两侧的弧形拱肋,以及联接拱肋和桥面结构的网状吊杆、拱上立柱，所述拱肋之间设置有多个横撑，所述拱肋由空心钢管对接构成，所述空心钢管外表面包覆一层CA‑UHPC外包层；将CA‑UHPC引入网状吊杆拱桥的拱肋中，并且将CA‑UHPC材料和钢管进行组合，使该拱桥具有跨越能力强、受力高效、施工快速简便的特点。在工程建设中采用该拱桥可克服诸如大跨度混凝土拱桥自重过大、全钢拱桥厚钢板焊接难度大、成本高，以及CFST拱桥的常见缺点。
