Description

Two dimension prestressing U-shaped aqueduct corrugated tube network for location chip architecture

Technical field

This utility model relates to two dimension prestressing U-shaped aqueduct, especially relates to two dimension prestressing U-shaped aqueduct corrugated tube network for location chip architecture.

Background technology

U-shaped aqueduct is widely used in all kinds of water delivery engineering due to advantages such as its cross-section of river is good, the loss of flood peak is little, with a slim and graceful figure, good looking appearances.Groove body crack resistance is required that higher U-shaped aqueduct is generally double prestressed concrete structure, is all laid with presstressed reinforcing steel at groove body Parallel to the flow direction and along groove body hoop.Longitudinal rib (arranging along Parallel to the flow direction) is typically located in U-shaped aqueduct lower raft, linear generally straight line.Hoop muscle (circumferentially disposed along groove body) is the most consistent with groove body cross-section of river shape, is arranged in outside the cross-section of river, linear for straight line+semicircle+straight line.Crossing water owing to U-shaped aqueduct is internal, therefore require U-shaped aqueduct cracking resistance strict, the U-shaped aqueduct of such as Middle Line Project For Transferring Water From South To North requires that inner surface can not occur tension under each operating mode, therefore prestressing force corrugated tube location is particularly important；If corrugated tube irregularity occurs, at a distance of phenomenons such as design attitude deviation are bigger, stretch-draw and friction loss when putting, retraction loss directly affect the effective stress of presstressed reinforcing steel and the overall cracking resistance of groove body.

The structures such as existing highway, the box-girder of railroad bridge or tee girder, the most unidirectional prestressed structure, the most only it is longitudinally arranged presstressed reinforcing steel, and there is not the deep camber hoop flat bellows duct of U-shaped like aqueduct.The linear generally straight line+camber line+straight line of longitudinal prestressing muscle, is arranged in web or base plate, and generally monolayer is arranged.During construction, web or base plate regular reinforcement weld one section of straight reinforcing bar, it welds " well " font or longitudinal rib is positioned by "U" shaped positioning bar.Owing to web or base plate are relatively thin, if occurring, positioning bar is easily finely adjusted by deviation.

But, two dimension prestressing U-shaped aqueduct average physique is relatively big, and the two dimension prestressing U-shaped Prefabricated aqueduct that such as south water to north Shahe uses, span centre base plate thickness is 0.9m, and end bottom plate thickness is 1.7m, and longitudinal prestressing muscle 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 adjust during reinforcing bar cage hoisting.And groove body ring orientation prestress rib is monolayer layout, duct is flat bellows, positions the strictest to duct and is easier to cause deviation.
