Method for constructing foundation pit in situ and newly adding underground structure below existing preserved building
The invention relates to a method for constructing a foundation pit in situ and newly adding an underground structure below an existing preserved building. The method comprises the steps of constructing vertical bearing members in soil layers around the existing preserved building; constructing working wells at peripheries of the vertical bearing members, and constructing bearing beams in the working wells, wherein the bearing beams are located below the existing preserved building; connecting the bearing beams with the vertical bearing members through transfer beams, so that a stress system is transmitted to the vertical bearing members from the bearing beams through the transfer beams; carrying out excavating downwards in the working wells around the existing preserved building in a layered manner to form a peripheral part of the foundation pit, and excavating the soil layers below the bearing beams and the transfer beams; and finally forming the foundation pit. The method has no damage to the existing preserved building, and stable support and effective protection can be provided; and large-scale construction of the foundation pit below the existing preserved building can be performed directly, and the requirement for the area of a working site is not high.
本发明涉及一种在既有保留建筑下方原位施工基坑的方法，包括：围绕既有保留建筑向土层内施工竖向承载力构件；在所述竖向承载力构件的外围施工工作井，并在所述工作井中施工承载梁，所述承载梁位于所述既有保留建筑下方；将所述承载梁通过转换梁与所述竖向承载力构件连接，使得受力体系由所述承载梁通过所述转换梁传递至所述竖向承载力构件；在所述工作井中围绕所述既有保留建筑分层向下挖掘形成基坑的周边部分，并在所述承载梁和所述转换梁的下方挖掘土层，最终形成基坑。本发明不会对既有保留建筑造成任何的损伤，且可以提供稳定的支撑和有效的保护；可直接在既有保留建筑的下方进行大规模施工基坑，对于作业场地面积的要求不高。
