Construction method of thin-wall prestressed concrete aqueduct
The invention provides a construction method of a thin-wall prestressed concrete aqueduct. The concrete aqueduct is made of concrete and an expanding agent, wherein the mass ratio of the concrete to the expanding agent is 79:1. The concrete with the expanding agent is used as a plug, a post-cast strip and second-stage concrete of a large-size concrete structure, the full section of a hydraulic structure is of a shrinkage-compensating concrete structure, and the concrete with the expanding agent is used for a large-span thin-wall prestressed aqueduct structure. The large-span thin-wall prestressed aqueduct of the large-size concrete structure is high in structural strength and low in cost, and the construction period is shortened. The raw materials used in the method are easy to obtain, lowin cost, thin in wall, high in strength and large in span, and the method has good practical application value.
本发明提供一种薄壁预应力混凝土渡槽施工方法，混凝土渡槽的制作原料为混凝土中加入膨胀剂，所述混凝土和膨胀剂的质量比为79:1。所述添加膨胀剂的混凝土作为大体积混凝土结构的堵头、后浇带和二期混凝土使用，水工建筑物全断面采用补偿收缩混凝土结构，所述添加膨胀剂的混凝土用于大跨度薄壁预应力渡槽结构。本发明大体积混凝土结构的大跨度薄壁预应力渡槽结构强度高，费用低且节约工期。本发明所用的原料易得，成本低，薄壁、高强、大跨度，具有较好的实际应用价值。
