Construction method suitable for unequal-depth adjacent foundation pits in soft soil area
The invention provides a construction method suitable for unequal-depth adjacent foundation pits in a soft soil area, which comprises the following steps of: downwards excavating a first depth in a deep foundation pit support structure and a shallow foundation pit support structure at the same time, and dismantling a common foundation pit support structure corresponding to the first depth; a shallow foundation pit bottom plate and an inverted bracket connecting structure are constructed at the position corresponding to the first depth in the same period, the shallow foundation pit bottom plate and the inverted bracket connecting structure are jointly poured into an integral structure, excavation continues to be conducted downwards in the deep foundation pit support structure by the second depth, and a top beam is constructed at the top of the remaining common foundation pit support structure; and the third depth continues to be excavated downwards in the deep foundation pit support structure, and a deep foundation pit bottom plate and a remaining main body structure are constructed. According to the construction method, a deep foundation pit and a shallow foundation pit do not need to be independently constructed, the construction method can be adopted for construction in the same period, the construction efficiency can be greatly improved, and the engineering cost is reduced.
本发明提供一种适用于软土地区不等深相邻基坑的施工方法，通过在深基坑围护结构内以及浅基坑围护结构内同期向下开挖第一深度并拆除第一深度对应的共有基坑围护结构，在第一深度对应的位置同期施作浅基坑底板以及倒牛腿连接结构，浅基坑底板和倒牛腿连接结构共同浇筑为整体结构，继续在深基坑围护结构内向下开挖第二深度，并在剩余共有基坑围护结构的顶部施作冠梁，在深基坑围护结构内继续向下开挖第三深度，并施作深基坑底板和剩余主体结构。本申请不需要单独施作深基坑和浅基坑，可以采用同期施工方式进行施作得到，能够大幅提高施工效率，降低工程成本。
