Abstract:This paper briefly reviews the development history of extracorporeal prestressing, describes the technical characteristics of extracorporeal prestressing, the scope of application, and illustrates the specific application of extracorporeal prestressing through an example, and looks forward to the prospects of the application of extracorporeal prestressing

Abstract:This paper introduces the development of OVM new type anchorage, epoxy spraying steel strand and geotechnical anchor technology and its engineering application. With the further popularization and application of these new products and technologies, it will certainly play a more positive role in promoting the development of geotechnical engineering technology.

Abstract:Zhangzhou Battle Bridge is the first short tower partially cable-stayed bridge in China. The upper part of the main tower is equipped with a circular arc-shaped saddle of internal and external steel pipes, and anti-slip anchorage is provided at the exit of the cable-stayed cables on both sides. The cable is symmetrically anchored to the girder through the inner steel pipe. The outer wrapped PE galvanized steel strand at the cable saddle is bare, and when the construction is completed, the inner pipe and anti-slip anchorage are filled with epoxy cement mortar. Tensioning construction adopts symmetrical synchronous tensioning at both ends.

Abstract:Steel stranded diagonal cable technology is widely used in bridge engineering, but not much used in public buildings. The design and construction of steel roof cover diagonal cable of stadium in Cixi City, Zhejiang Province, has carried out a useful exploration for the design and construction of prestressed diagonal cable in China's construction engineering, and has achieved better appearance and use effect.

Abstract:It introduces the comprehensive application technology of non-bonded prestressed concrete technology in industrial plant structure, and briefly describes the design characteristics, construction points and technical and economic evaluation of large-span super-long 141m continuous beams, wide flat beams, reverse beams, flat plates and other structures.

Abstract:LSDKB main console operation panel adopts membrane switch, all keys and indicators are made on the panel, which not only makes the panel operation more convenient and wiring simpler, but also provides a guarantee for the miniaturization and light weight of the main console.
