Description
Technical field
The present invention relates to two dimension prestressing U shape aqueduct, especially relate to two dimension prestressing U shape aqueduct corrugated tube location mesh sheet structure.
Background technology
U shape aqueduct is widely used in all kinds of water delivery engineering due to advantages such as its water-carrying section are good, head loss is little, with a slim and graceful figure, profile is attractive in appearance. Groove body splitting resistance is required that higher U shape aqueduct is generally two dimension prestressing concrete structure, at groove body Parallel to the flow direction and along groove body ring to being all laid with presstressed reinforcing steel. Longitudinal rib (is arranged along Parallel to the flow direction) and is generally arranged in U shape aqueduct lower raft, linear is generally straight line. Ring is general consistent with groove body water-carrying section shape to muscle (along groove body ring to layout), is arranged in outside water-carrying section, and linear is straight line+semicircle+straight line. Owing to water is crossed in U shape aqueduct inside, therefore being required by U shape aqueduct resistance to cleavage strict, the U shape aqueduct of such as south water to north center line requires that tensile stress can not occur under each operating mode in internal surface, therefore prestress corrugated tube location is particularly important; If corrugated tube irregularity occurs, at a distance of phenomenons such as design position deviation are bigger, stretch-draw and frictionloss when putting, retraction loss directly affect the effective stress of presstressed reinforcing steel and the overall resistance to cleavage of groove body.
The structures such as the cased beam of existing highway, railroad bridge or T-shaped beam, are generally unidirectional prestress structure, are namely only longitudinally being furnished with presstressed reinforcing steel, and the deep camber ring that there is not U-shaped like aqueduct is to flat bellows duct. Longitudinal presstressed reinforcing steel is linear is generally straight line+camber line+straight line, is arranged in web or base plate, and is generally individual layer and arranges. During construction, welding one section of straight reinforcing bar on web or base plate regular reinforcement, on it, longitudinal rib is positioned by welding " well " font or " U " font positioning bar. Owing to web or base plate are thinner, if occurring, positioning bar is easily finely tuned by deviation.
But, the two dimension prestressing U general build of shape aqueduct is relatively big, the two dimension prestressing prefabricated aqueduct of U shape that such as south water to north Shahe uses, it is 0.9m across middle base plate thickness, end bottom plate thickness is 1.7m, and longitudinal presstressed reinforcing steel is rebuilding, and duct is circle corrugated pipe;Lower floor's bellows core line is straight line, and upper strata bellows core line is camber line. Lower floor's presstressed reinforcing steel if there is deviation, owing to base plate is thicker, is therefore difficult to adjustment in reinforcing bar cage hoisting process. And groove body ring orientation prestress rib is individual layer layout, duct is flat bellows, and location, duct more strictly and is more easily caused deviation.
