Method for reducing foundation pit excavation by raising basement core tube elevation
The invention provides a method for reducing excavation of a foundation pit by raising the elevation of a core tube of a basement, which is characterized in that the core tube elevation of the whole basement is raised to ensure that a stair does not need to be steered, the stair section of the stair of the basement and the stair section of a main building are designed to be consistent from positive and negative zero, and the elevator door opening layer elevation is raised to reduce excavation of the foundation pit. And elevator foundation pit excavation is reduced. By raising the elevation of the core tube, excavation of a foundation pit of the elevator and a water collecting pit of the fire elevator can be reduced, and the buried depth of a structure foundation can be reduced. The fire-fighting linkage is easy to realize, and the fire-fighting elevator sump is arranged beside the elevator foundation pit, so that the water pumping height of a water pump is reduced. As the construction pit is shallow, the excavation area is small, and time and labor are saved.
本发明提供一种通过抬高地下室核心筒标高减少基坑开挖的方法，其特征在于：通过将整个地下室的核心筒标高抬高，保证楼梯不需要转向，设计从正负零到地下室的楼梯与主楼的楼梯的梯段一致，并将电梯开门层标高抬高，减少电梯基坑开挖。本发明通过抬高核心筒的标高，可以减少电梯的基坑和消防电梯集水坑的开挖，可以减少结构基础埋深。消防联动易实现,消防电梯集水坑设置在电梯基坑旁边，有利于减少水泵泵水高度。因为施工地坑浅所以开挖面积小，省时省工。
