Ultra-high performance concrete light U-shaped aqueduct body
The invention discloses an ultra-high performance concrete light U-shaped aqueduct body. The aqueduct body is composed of ultra-high performance concrete and reinforcing steel bars embedded in the ultra-high performance concrete. The aqueduct body comprises a U-shaped aqueduct wall and a top beam at the top of the aqueduct wall; the root of the top beam is connected with the top of the aqueduct wall through a vertical section; the thickness of the aqueduct wall is not less than 30mm; the width of the top beam is 1.0-10.0 times of the thickness of the aqueduct wall; the thickness of the end part of the top beam is 0.5-3.0 times that of the aqueduct wall; the thickness of the root of the top beam is 1.0-6.0 times of the thickness of the aqueduct wall, the area of the top beam is 10-30% of the area of the cross section of the aqueduct body, the height of the straight section of the top beam is 0.2-1.0 time of the inner diameter of the aqueduct body, the depth-to-width ratio of the aqueduct body is 0.55-1.0, and the ratio of the height of the aqueduct body to the thickness of the aqueduct wall is 30-50; the reinforcing steel bars comprise steel meshes and constructional ribs, the steelmeshes are located in the aqueduct wall, and the constructional ribs are located in the top beam. By improving the material and structural size of the aqueduct body, the U-shaped aqueduct body whichis lighter and thinner, more convenient to construct and higher in durability is obtained, and the problems that an existing U-shaped aqueduct is large in dead weight and poor in durability are solved.
本发明公开一种超高性能混凝土轻质U形渡槽槽身，槽身由超高性能混凝土与埋设在其中的钢筋组成，槽身包括槽壁和槽壁顶部的顶梁，槽壁呈U形，顶梁的根部通过竖直段与槽壁顶部连接，槽壁厚度不小于30mm，顶梁宽为槽壁厚度的1.0～10.0倍，顶梁端部厚度为槽壁厚度的0.5～3.0倍，顶梁根部厚度为槽壁厚度的1.0～6.0倍，顶梁面积为槽身横断面面积的10％～30％，顶梁的直段高度为槽身内径的0.2～1.0倍，槽身的深宽比为0.55～1.0，槽身高度与槽壁厚度的比值为30～50；钢筋包括钢网片和构造筋，所述钢网片位于槽壁内，构造筋位于顶梁内。通过对槽身的材料和结构尺寸进行改进，得到更为轻薄、施工更为方便、耐久性更高的U形渡槽槽身，解决了现有的U形槽自重大、耐久性差的问题。
