Ultra-high-performance concrete ribbed plate type light rectangular aqueduct body
The invention discloses an ultra-high-performance concrete ribbed plate type light rectangular aqueduct body. The aqueduct body is composed of ultra-high-performance concrete and steel bars embedded in the ultra-high-performance concrete, the aqueduct body comprises side walls and a bottom plate, and two sides of the bottom plate are connected with the bottoms of the side walls respectively; the tops of the side walls extend outwards to be provided with cantilever plates, the plate width, in the middle section of the aqueduct body, of the cantilever plates is 1.0-30.0 times of the thickness ofthe side walls, and the average plate thickness of the cantilever plates is 1.0-3.0 times of the thickness of the side walls; the steel bars comprise structural bars and steel meshes, the structuralbars are located in the cantilever plates, and the steel meshes are arranged in the side walls and the bottom plate respectively; the thickness, in the middle section of the aqueduct body, of the sidewalls is not smaller than 30mm, the height-to-thickness ratio, in the middle section of the aqueduct body, of the side walls is 36-60, the depth-to-width ratio of the water passing section of the aqueduct body is not larger than 0.9, and the thickness, in the middle section of the aqueduct body, of the bottom plate is 1.0-2.0 times of the average thickness of the side walls; and transverse annular ribs are arranged on the aqueduct body and distributed in the longitudinal direction of the aqueduct body at intervals, the distance between every two adjacent transverse annular ribs ranges from 1.0m to 2.5m, and the width ranges from 60mm to 200mm. By improving the material and the structural size of the aqueduct body, an aqueduct is lighter and thinner, and the durability is higher.
本发明公开一种超高性能混凝土肋板式轻质矩形渡槽槽身，所述槽身由超高性能混凝土与埋设在其中的钢筋组成，槽身包括侧墙和底板，底板的两侧分别与侧墙的底部连接；侧墙顶部向外延伸设置悬臂板，槽身中段的悬臂板的板宽为侧墙厚度的1.0～30.0倍，悬臂板的平均板厚为侧墙厚度的1.0～3.0倍；钢筋包括构造筋和钢网片，构造筋位于悬臂板内，侧墙和底板内分别为钢网片；槽身中段的侧墙厚度不小于30mm，槽身中段侧墙高厚比为36～60，槽身过水断面的深宽比不大于0.9，槽身中段底板厚度为侧墙平均厚度的1.0～2.0倍；槽身设有横向环肋，横向环肋沿槽身的纵向间隔分布，相邻横向环肋的间距为1.0～2.5米，宽度为60～200mm。通过对槽身的材料和结构尺寸进行改进，使渡槽更为轻薄、耐久性更高。
