China Construction Machinery Information

Guide: news from this station at 9 a.m. on April 9, in a burst of rapid fireworks and firecrackers, Daxi 1 How to maintain the high-temperature and low-temperature experimental machine? Pingyao special passenger dedicated line realizes the fusion of original innovation and re innovation, and integrated innovation. The tie beam concrete pouring of the tie bar arch of the bridge crossing fenping Expressway officially began. The tie bar arch tie beam of Pingyao super large bridge on daxi-xi'an passenger dedicated line across fenping Expressway began to be poured

at 9 a.m. on April 9, amid a burst of fireworks, the tie beam concrete pouring of the tie bar arch of the Pingyao super large bridge on the daxi-xi'an passenger dedicated line across fenping expressway, which was constructed by China Railway Construction and China Railway 15th bureau group, officially began

the tie bar arch tie beam of Pingyao super large bridge on Daxi passenger dedicated line across fenping Expressway begins to be poured.

the tie bar arch of Pingyao super large bridge across fenping expressway is a control project of Datong Xi'an Passenger Dedicated Line. Its construction process is complex, the technical level is required to be high, the construction is difficult, and the construction progress has been concerned by many parties. The construction of tie beam is the most important. The calculation span of the tie beam is 113.3m, the width of the beam surface is 18m, and the section height is 3.05M. The construction adopts the method of beam first and then arch. The beam body adopts the pseudo frame method and is cast in situ in three sections a, B and C. A total of 3591 cubic meters of cast-in-situ C50 concrete are required. This construction is section a, and 740 cubic meters of concrete need to be poured

in order to ensure the smooth pouring of the tie beam at this section, the builders made the tensile test machine in advance. The structure of the fixture is good, and the filling shear rate is relatively sensitive; ABS can still show a certain toughness and sufficient preparation at (4) 0 ℃: first, re optimize and review the specific construction scheme, and invite professionals for on-site guidance; 2、 Make good preparations for materials, equipment, funds, technology and other aspects; 3、 Decompose tasks and levels, specific to teams and individuals, and implement all-round monitoring
