| 摘 要： | 王府园三期基坑支护工程周边施工场地狭小,为解决地下室施工时基坑周边无材料堆放场地、加工场地及基坑大量土体同时开挖外运困难等问题,在第1层角撑四周设置材料堆场及操作平台、在基坑第1、2道对撑位置设置了栈桥,进而改善了土方场内运输条件,提高了土方开挖外运的效率,缩短了工期,节约了工程造价。

| Abstract: | The construction yard around the foundation excavation support engineering of the third stage of Wangfuyuan project is narrow,so there is no place around foundation pit for material stacking and material treating,and it is difficult for soil excavation and transportation.For dealling these problems,the material stacking site and working platform is placed around the angle stiffening of first layer,and trestle bridge is place around the first and second symmetrical support.These measures improve soil transpo... |
