Research on sliding formwork construction technology for shallow circular grain silos in Zhenjiang southern Jiangsu Province
This paper studies the construction technology of slipform construction for 10 shallow circular silos in the Suzhou South Reserve Grain in Danyang City,Zhenjiang.The project uses a slipform system with 54 lifting brackets and 54 6-ton jacks.research shows that a water-cement ratio of 0.43 and a weight of 2 300 kg/m3 for the concrete mix can en-sure the strength out of the form is controlled between 0.2 MPa～0.4 MPa.By optimizing the construction procedures,two specialized teams completed the slip construction of 10 shallow circular silos in 28 days.The construction technique of 300 mm layer-by-layer pouring and 2-hour-up interval was used,effectively ensuring the quality of the concrete.Com-bined with the verification of actual engineering,this technical solution can ensure that the technical indicators such as flatness and verticality of the shallow circular silo slipform construction meet the design.
