Embodiment Construction
[0034] In conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
[0035] The main canal aqueduct C1 standard of the Qianzhong Water Conservancy Project Phase I project is the main channel of the grassland slope aqueduct with a continuous rigid structure of (95.95 + 180 + 95.95) m and a total length of 371.9 m. The main channel of the Xujiawan aqueduct is (95.95 + 2 × 180 + 95.95 )m continuous rigid structure, with a total length of 551.9m and a beam top width of 9.5m. Each main pier "T" structure is divided into 24 symmetrical beam sections in the longitudinal bridge direction. It is 12 meters (0# section), 8×3.0 meters, 10×3.5 meters, 6×4.0 meters, 2.0 meters (closed section), and the side-span cast-in-place section is 4.95 meters long.
[0036] There are 7 closing sections in the whole bidding section, which are 2 side span closing sections and 1 middle span closing section of Caodipo Aqueduct, 2 side span closing secti...
