Description
Technical field
The utility model relates to the Building technology application, particularly a kind of hydraulic formwork system for high pier construction.
Background technology
Mountain highway and railroad bridge ratio are large, span of bridge is larger, high pier is higher, present high pier maximum height reaches 195m (the Hezhang grand bridge that Hezhang County, Bijie Prefecture, Guizhou Province is domestic), bridge can well connect valley and gully, assurance road alignment, raising car speed, save the advantages such as cost of transportation, saving Land resources in mountainous areas, so the high pier of Bridges in Mountainous Areas is comparatively extensive.For high pier construction, the technique of comparative maturity mainly contains following several at present:
1, climbing formwork for construction
Creeping formwork is mainly pre-buried hanging seat built-in fitting in concrete, mounting guide rail and bearing frame, and template is climbed by guide rail.This system need to be before each concreting, the built-in fitting of pre-buried special use, high to the pre-buried required precision of built-in fitting, pre-buried control difficulty, working load and template system deadweight all reach the concrete of having built, and require high to concrete strength, concrete is easy to destroy, can not form flowing water and work continuously, built-in fitting and template have high input, and construction cost is high.Because cost is high, so choice for use is not generally done by unit in charge of construction.
2, over-form construction
Turning over mould is to adopt the circulation of two-stage template to turn over the process that rises, and over-form construction template use amount is large, and speed of application is fast, and template is mainly stressed to drawing by pull bar, and build needs remove and reinstall template at every turn, exists certain dangerous in construction.Because speed of application is very fast, outward appearance is easy to control, and uses general in high pier construction.
3, slding form operation
Sliding formwork is that template is fixed in enclosure, working load, template is stressed and the deadweight be passed to carriage, be passed to vertical rod by jack.The native system template drops into little, but pre-buried vertical rod expense is large, outward appearance, linear and verticality control difficulty in construction, concrete is had relatively high expectations, and sliding time is restive, and when sliding, template and concrete frictional resistance are large, system easily damages, and has certain danger.Because the construction outward appearance is difficult to solve, therefore generally do not select slding form operation.
4, sliding turning in conjunction with construction
it is sliding that to turn in conjunction with construction be on the slding form operation basis, fixing stencil design is become can remove and install, take full advantage of sliding formwork and the advantage of turning over mould, solved the restive and concrete initial set time trouble problem of slding form operation outward appearance, this system template is removed and is quick for installation, reduce security risk, each inter process can form continuous productive process, thereby accelerating construction progress, improve work efficiency, greatly save cost, the automatic sprinkler fire-extinguishing system that adopts has been guaranteed high pier health quality, it is the present mountain area most advanced system of high pier construction that cunning is turned in conjunction with template system, overcome creeping formwork, turn over mould, the shortcoming of sliding formwork.
