Abstract
The utility model provides a steel lining reinforced concrete stridees across structure for water delivery, including strideing across main arch structure, stride across in the main arch structure along the pre-buried cross-sectional area that has of length direction for pipy steel sheet inside lining, stride across main arch structure both ends and set up the hunch seat, the inside connection steel pipe of burying underground of hunch seat to with the both ends butt joint of strideing across the inside steel sheet inside lining of main arch structure. The method solves the problems of high construction difficulty and high investment of the existing method. Belongs to the technical field of water conservancy and hydropower engineering.
Description
Technical Field
The utility model relates to a steel lining reinforced concrete stridees across structure for water delivery belongs to hydraulic and hydroelectric engineering technical field.
Background
When a water delivery structure of a hydraulic engineering pipeline meets terrains such as valleys, gullies, rivers and the like with large width and depth, commonly used structures comprise an arch aqueduct, a continuous rigid frame aqueduct, an arch inverted siphon and the like. The arch aqueduct and the continuous rigid frame aqueduct can be directly arranged at the water surface line elevation position for directly conveying water, but the span is often large, the construction difficulty is also large, and the investment is very high. The arch inverted siphon selects to build an arch bridge at a position with proper height and span and conveys water through a pressure pipeline, and compared with an arch aqueduct or a continuous rigid frame aqueduct structure, the arch inverted siphon can reduce the span and the construction difficulty, but because an arch ring upper bent bridge and a pipeline are additionally arranged, the engineering investment phase change is small. Therefore, the utility model provides a steel lining reinforced concrete stridees across structure for water delivery.
Disclosure of Invention
The utility model provides a steel lining reinforced concrete stridees across structure for water delivery to it is big to solve the current method construction degree of difficulty, the high problem of investment.
In order to solve the problems, the steel-lined reinforced concrete crossing structure for water delivery comprises a crossing main arch structure, wherein a steel plate lining with a tubular cross-sectional area is pre-embedded in the crossing main arch structure along the length direction, arch bases are arranged at two ends of the crossing main arch structure, and connecting steel pipes are embedded in the arch bases and are butted with two ends of the steel plate lining in the crossing main arch structure.
In the crossing structure, the crossing main arch structure is a hollow reinforced concrete box culvert structure, the inner wall of the box body is lined with steel plates to form a steel plate lining, the axis is arch-shaped, and the crossing main arch structure can be set into a multi-box structure according to the water delivery requirement;
in the spanning structure, the arch support is of a reinforced concrete structure;
in the spanning structure, the connecting steel pipe and the steel plate lining in the spanning main arch structure have the same section structure and material;
compared with the prior art, water delivery structure mainly utilizes arch reinforced concrete box culvert to undertake load such as structure dead weight, water weight, utilizes the steel sheet lining of box inner wall to undertake internal water pressure and prevention of seepage, can exert reinforced concrete owner arch structure's bearing capacity, the anti internal water pressure and the prevention of seepage ability of the inside steel sheet lining structure of make full use of reduce arch type inverted siphon owner arch ring upper portion framed bent bridge and pipeline structure's arrangement to reach and simplify the construction procedure, shorten construction period, reduce the purpose of engineering investment.
