Abstract
The present invention includes the following steps: removing protective arch of arcuated on-arch construction and filling, then changing arched bridge into beam-arched on-arch construction bridge. The old bridge has no need of reinforcement, only has need of reducing self-weight, and its load-bearing capacity also can be raised naturally.
Description
The present invention relates to a kind of method that a kind of arch building on extrados bridge in the arch bridge is changed into the beam-arch bridge.
The arch building on extrados bridge is a modal bridge type (as shown in Figure 1) in the arch bridge, and this type of arch bridge of China is ten hundreds of.Its arch top of most arch bridges protect arch and filler weight very big, the deadweight that has increased the bed rearrangement bridge.Along with the increase of the carrying capacity of vehicle in the communications and transportation, some arch bridges that built up do not satisfy the demand that load-carrying increases, and transformation needs reinforcement.
Reinforce old arch bridge now and adopt following several method usually:
1. below main arch, thicken main arch, increase the arch ring cross section;
2. eliminate abutment displacement with incremental launching method;
3. use the external prestressing strengthening bridge.
These methods all are the methods that strengthens, and its shortcoming is that difficulty of construction is big, and have increased deadweight again when reinforcing old bridge, also are difficult for the effect that reaches satisfied with higher cost.
Guiding theory of the present invention is Reduction of Students' Study Load, promptly alleviates the arch bridge deadweight to greatest extent, need not strengthen just to reach the purpose that improves weight bearing power naturally.
Below in conjunction with accompanying drawing, specify implementation method of the present invention.
Fig. 1 is the schematic diagram of arch building on extrados bridge.
Fig. 2 is for removing the bridge floor beam slab, protecting the arch building on extrados bridge schematic diagram behind arch and the filler.
Fig. 3 is for becoming the schematic diagram of beam-arch bridge after reconstructing.
Referring to Fig. 1, Fig. 2, at first open bridge floor beam slab 6, remove above the protecting of main arch 1 and spandrel arch 2 hogbacks and encircle and filler 4, keep spandrel arch pier 3, Spandrel arch 2 can keep in the ordinary course of things, also can remove if necessary; On spandrel arch pier 3, build then column 7; At last at each column 7 With vault 8 upper cover with bridge floor beam slab 6, the beam-arch bridge. Vault 8 can form entity section 5 with bridge floor beam slab 6, and vault 8 like this Effective cross-section obviously increase. Entity section 5 can be regarded the synthetic of column 7 and beam slab 6 as.
