Above -mentioned arch bridge structure can reduce arched bridge engineering cost, ensures the arched bridge engineering quality.
Description
Technical field
The utility model belongs to arch bridge structure field and in particular to a kind of arch bridge structure.
Background technology
Along with the increasingly quickening of China's Urbanization Construction speed, river course is built bridge with convenient adjacent two places between
Traffic, promote the economic development of two places to become the important propulsion engineering project of Urbanization Construction.And arch bridge exactly relies on it excellent
U.S., the mellow and full moulding of curve, receive the favor of the various places people.
At present, the main arch ring of existing arch bridge main arch ring generally adopts Portland cement more than 40 for the strength grade to make
For the concrete material pouring.However, portland cement occurs the phenomenon of volumetric expansion in aquation and hardening process, and
After hardening in atmosphere, volume can shrink again and produce microcrack（Naked eyes are difficult to observe）, and then reduce main arch coil structures
Density, the performance indications such as impervious, freeze proof, anticorrosive of impact structure, be unfavorable for effectively guaranteeing the safety jail of arch bridge structure
By property.If but the whole micro-expansion cement of main arch ring, as the concrete material pouring, certainly will increase construction costs again（Ordinary silicon
The unit price of acid salt cement is about 1000 yuan/ton, and micro-expansion cement is about 1300 yuan/ton）, reduce unit in charge of construction's income.
Based on this, applicant considers that design is a kind of and can reduce arch bridge construction costs it is ensured that the arch bridge of arch bridge construction quality
Structure.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How a kind of energy is provided
Enough reduce arch bridge construction costs it is ensured that the arch bridge structure of arch bridge construction quality.
In order to solve above-mentioned technical problem, the utility model employs following technical scheme：
A kind of arch bridge structure, including main arch ring and main arch ring supporting structure；Described main arch ring is the curved reinforcing bar of profile
Xoncrete structure；It is characterized in that：Described main arch ring is arranged at intervals with least three common pouring areas, institute on its radian direction
State the concreting that common pouring area is obtained by the ordinary cement that strength grade is not less than 40；Two adjacent ordinary cements
