Successive Liang Qiao all is or so line endlong 185.5 meters, use advocate cross 88 rice, edges to cross program of 48 meters of designs to span Beijing hides high speed, the structure is simple case cell, change height, become sectional box roof beam, adopt the cantilever that hang basket to irrigate the construction that build a way, construction craft precision of trival, technology is tall, safe the risk is big.
From June 16, 2017 since construction, the person that 20 bureaus build iron in is aimed at shutdown of winter Gao Han 4 months create problem of insecurity of time limit for a project, this year after go back to work, they are grabbed catch construction gold season, do not forget first new meritorious service of Zhangli of the heart paint blue print, Beijing that build a dream, elaborate design, elaborate organization, comply with law advance. Difficulty, tensioning to technology of simple case room, note the technical precision such as the oar difficult problem, this project ministry chose picked troops strong will strengthen process canal to accuse, stare at working procedure link closely, concrete cast-in-place adopts heavy-duty pump car to be irrigated quickly build fast brace up pound a method, steel skeining thread is tensioning, note an oar how to pledge engineer whole process is supervised, wrap up is enclothed completely after conserve adopts besmear to brush conserve fluid, made sure high quality of dimension of successive bridge linear, geometry, hypostatic exterior is shut.
