某厂高速动平衡试验室工程,由我公司七○七工程队承建。该试验室中,设有高速动平衡试验筒体,体长20米,内衬直径9米钢壳,外包1.2米厚钢筋混凝土的混合结构体。工程要求外包层钢筋混凝土必须密实並紧贴钢壳体,而且要待钢壳体在基础上就位按装后,才可进行施工。特别是钢壳体底部,钢筋密集,空间面积狭小,施工人员无法进入,给混凝土的浇捣带来困难。因此,如何解决基础的大量混凝土灌输,成为施工
The high speed dynamic balance laboratory project of a factory was constructed by our company’s 7,000 engineering team. In this laboratory, there is a high-speed dynamic balance test cylinder with a body length of 20 meters, a lined steel shell with a diameter of 9 meters, and a 1.2 meters thick reinforced concrete mixed structure. The project requires that the reinforced concrete of the overclad layer must be compacted and tightly attached to the steel shell, and the steel shell must be installed on the foundation before installation. In particular, at the bottom of the steel shell, the steel bars are dense and the space area is small, and the construction personnel cannot access them, which causes difficulty in pouring the concrete. Therefore, how to solve the foundation of a large amount of concrete infusion becomes construction
