Abstract
The utility model belongs to the field of the bridge reinforcing technology, and particularly relates to a two-way curved arch bridge reinforcing structure. The two-way curved arch bridge reinforcing structure mainly aims at solving the technical problems that a traditional two-way curved arch bridge is simple in structure, low in strength and short in service life. The two-way curved arch bridge reinforcing structure comprises two-way curved arch tiles and arch ribs. Bottom formworks are arranged on the lower portions of the two-way curved arch tiles and connected with the arch ribs through reinforcing steel bars. Cylindrical supporting bodies are arranged between the bottom formworks and the two-way curved arch tiles. Concrete body structures are further arranged between the bottom formworks and the two-way curved arch tiles. Micro-expanding concrete is adopted in the concrete body structures. The two-way curved arch bridge reinforcing structure is easy and convenient to use, the service life of a two-way curved arch bridge is effectively prolonged, the strength of a bridge body is enhanced, meanwhile, the technical problem that the bridge body is prone to cracking is solved, and the use security coefficient of the two-way curved arch bridge is effectively increased.
Description
Technical field
The utility model belongs to Technology Bridge Strengthening field, relates to specifically a kind of Reinforcing Double-curve Arch Bridge structure.
Background technology
China is in the building course of double curvature arched bridge, realize already the building technology of " breaking the whole up into parts; collection zero is whole ", it is low that it has cost, materials are economized, easy construction, the feature of good looking appearance, but due to bridge in use, along with the growth of the length of service and the increase of the traffic volume, there is crack in bridge part, also can reduce gradually followed by its supporting capacity, so just seem more outstanding important for the bridge strengthening of double curvature arched bridge, effectively revise by part, can effectively increase the length of service and the load level of double curvature arched bridge.
Summary of the invention
Goal of the invention of the present utility model:
Mainly be to provide a kind of repair structure of double curvature arched bridge simply and easily, can effectively increase the length of service of double curvature arched bridge, increase the bearing load of bridge, construction technology is simple, successful.
The technical solution of the utility model is:
A kind of Reinforcing Double-curve Arch Bridge structure is provided, comprise arch-wave and arch rib, bottom at arch-wave is provided with soffit formwork, soffit formwork is connected with arch rib by reinforcing bar, between soffit formwork and arch-wave, be provided with columniform supporter, between soffit formwork and arch-wave, be also provided with concrete body structure, described concrete body structure adopts microdilatancy concrete.
The beneficial effects of the utility model are: by the reinforcing of simple bridge pontic, effectively raise supporting capacity and the application life of pontic, for country has saved the fund input of infrastructure.
