| Abstract: | The project of crossing over the yellow river which transport west gas to east adopted of the form of hanging the cable tube bridge to cross over, and the tower foundation adopted whole extension type concrete foundation. Main frusta anchor-reinforce and wind frusta anchor-reinforce adopted the gravity-concrete anchor-reinforce frusta. In winter warm-shed construction, the concrete surface appeared a great deal of crack after removing the mold, through design, material assorted, construction and maintain, etc. analysis and test, the reason of the crack appearing is put forward, and the repair processing measure is given out. The project has already completed for five years now, and the result is good. |
