芨芨槽子特大桥位于乌鲁木齐天山区,全长1000m。全桥钻孔灌注桩170余根,工程量达2400余延米。该处地质上部地层为碎石和卵石,下层为较硬的灰板岩,桩基础施工直径要求为1.00～1.25m,深度在10.0～25.0m左右。特硬的地质为施工带来极大难度。
芨 芨 trough bridge is located in Urumqi Tianshan District, a total length of 1000m. More than 170 full-bridge bored piles, the project amounted to more than 2,400 meters. The upper part of the geological formations are gravel and pebbles, and the lower layer is the harder gray slate. The diameter of pile foundation construction is 1.00 ~ 1.25m and the depth is about 10.0 ~ 25.0m. Very hard geology for construction brought great difficulty.
