50米T梁浇注方法(国外英文资料) Shallow analysis of precast construction technique of 50mb concrete T beam Author:? Anonymous?? Source:? Original?? Time:? April 14, 2010?? 27 hits: With the emergence of prestressed concrete technology, novel prestressed concrete Bridges is developed with extraordinary speed, all kinds of bridge are constantly emerging. Early in the 21st century, the application technology of the long-span 50 m T beam have been mature and popular, and 50 m T beam precast technology, compared with 25 m, 30 mt beam at the bottom of the pedestal mold production, concrete pouring construction technology on to more complex systems, such as, for our bridge workers, will have a good professional technology and skilled construction experience. Hengshui, the author took part in the line in the section of the shide, jingjiu railway bridge crossing engineering construction (hereinafter referred to as the iron bridge), in the 50 m prestressed concrete T beam in the precast construction aspect, we adopted the following construction technology for reference. One, the concrete T beam pedestal prefabricated Make a t-girder Some projects in the past the beam use PVC board or leather do T beam bottom die, but after the casting caused by concrete hydration heat effect of PVC board or leather stretch forming creases, make the T beam bottom is not flat, water chestnuts and PVC plate juncture between bad handling of the slurry, water chestnut bottom forming textured, with a large number of T beams in this project to deny, and terrazzo bottom die hard, high temperature resistant, small scale, make the precast beam body surface smooth, bright and clean, the best results. The work of taichung The width between the platform and the platform is 4m, and the distance between each row is 1m. The base of the pedestal must be compacted,At the same time with a small gap between vibrators along corrugated pipe and steel insert vibrating, but will have to fight a vibrator to touch, corrugated pipe
