Lightweight channel aqueduct and preparation method thereof
The invention provides a light-weight channel aqueduct and a preparation method, the light-weight channel aqueduct comprises an aqueduct body, the outer wall of the aqueduct body is provided with a plurality of ring ribs distributed in the longitudinal direction, the aqueduct body is further provided with top ribs and longitudinal ribs, the aqueduct body is made of ultra-high performance concrete, and a prestressed steel cable is arranged at the position, close to the bottom, of the aqueduct body. A plurality of longitudinal joint bars are arranged at the position, close to the gentle slope section at the bottom, of the groove body, and the joint bars are inserted into poured concrete from the open holes of the end mold after pouring, vibrating and exhausting. The self weight of the tank body can be greatly reduced, the components of the ultra-high performance concrete are precisely proportioned, the stacking effect is remarkable, the inner wall of the tank body has high appearance and smoothness, and the strength of the tank body can be improved. The joint bar structure is arranged on the gentle slope section of the inner wall of the groove body, the post-insertion method is adopted for construction, an extrusion effect can be generated on the ultra-high performance concrete, the ultra-high performance concrete is stacked more tightly through transmitted pressure, bubbles are discharged in an accelerated mode, and the probability that surface voids and pitted surfaces appear is greatly reduced.
本发明提供一种轻量化航道渡槽及制备方法，包括槽体，槽体的外壁设有多个沿纵向分布的环肋，还设有顶肋和纵肋，槽体材质采用超高性能混凝土，在槽体靠近底部的位置设有预应力钢索。在槽体靠近底部缓坡段的位置设有多根沿纵向的插筋，插筋在浇筑、振捣和排气后从端模开孔中插入到浇筑的混凝土中。本发明能够大幅减轻槽体自重，超高性能混凝土的组分经过精确配比，堆积效应显著，槽体内壁具有较高的表观和光滑度，也能够提升槽体强度。在槽体内壁缓坡段设置的插筋结构，采用后插法施工，能够对超高性能混凝土产生挤压效应，利用传递的压力使超高性能混凝土堆积更加紧密，气泡加速排出，大幅降低表面蜂窝麻面出现的几率。
