上海国际金融中心工程提出了一种超深地下连续墙预埋剪力槽制作、安装的新方法,避免了传统剪力槽在多层地下空间开发中,尤其在超深基坑逆作法开挖施工时存在材料不易固定、易折断、易移位、后期凿出困难等难题。通过在地下连续墙钢筋笼内预埋由PVC方管组装而成的剪力槽预埋件,使基坑开挖后楼板与地下连续墙墙体交接处的锚固剪力槽更易凿出,且不会对墙体本身造成伤害。
Shanghai International Financial Center Project proposed a new method of making and installing embedded shear slots for ultra-deep underground continuous walls, avoiding the traditional shear groove in the development of multi-storey underground space, especially in the excavation of ultra deep foundation pit There is material difficult to fix when construction, easy to break, easy to shift, later difficult to dig and so on. Through the prefabricated shear-wall embedded parts made of PVC square pipe embedded in the underground continuous wall steel cage, it is easier to dig the anchorage shear groove of the floor of the foundation pit after excavation and the wall of the underground continuous wall and Will not cause damage to the wall itself.
