摘要
沈阳宝能环球金融中心项目总承包工程为沈阳地区开挖深度(整体深度约为27m,局部达到31m)及降水深度最大的基坑。为解决上述难题,结合本工程基坑支护特点,创造性地采用边填土边支护的新型支护形式施工坡道,该新型支护形式有效地将原有基坑护壁桩利用与钢管支护桩结合,形成一个结构稳定的坡道。施工完成后的坡道紧邻基坑支护桩,不占据现场主要施工区域,而且大大节约了现场施工场地。同时,该坡道施工周期短,而且能够达到提前通车的效果。
For the foundation excavation of Shenyang Baoneng Global Financial Center project,the excavation depth（ overall depth is about 27 meters,local depth reaches 31 meters） and precipitation is the deepest foundation excavation in Shenyang. To solve these problems,combined with the excavation project characteristics,creative side filling side support form of support construction ramps is used,the new support in the form of effective use of the original excavation retaining piles,steel pipe supporting piles are combined with retaining piles foundation excavation,which form a stable structure of the ramp.After the completion of construction of the ramp near the excavation pile,the ramp does not occupy the main construction site area, and a significant reduction in on-site construction site is achieved.Meanwhile,the ramp shorts construction period,achieves the effect of early traffic.
