Combined prefabricated retaining wall square pile foundation pit supporting structure and construction method thereof
The invention discloses a combined prefabricated retaining wall square pile foundation pit supporting structure and a construction method thereof. A stirring pile, a prefabricated pile, a connecting steel component, an externally-hung steel component and micro-expansion concrete are constructed to form a water-stopping and soil-retaining integrated underground retaining wall, so that supporting stability is provided for a foundation pit, and the foundation pit can be quickly and safely excavated within the enclosure range of the underground retaining wall; and in addition, an externally-hung part of the externally-hung steel component is used for being externally hung on a lining wall of a basement, a fertilizer groove needed by the lining wall of the basement during conventional construction can be omitted, excavation and filling of the foundation pit are reduced, the using area of the basement is enlarged, lining wall embedded steel bars of the basement can be reduced or even omitted, the underground retaining wall can serve as a permanent structure and does not need to be disassembled, the underground retaining wall can also serve as an outer wall of the basement in the construction stage and the using stage, and the construction cost is remarkably reduced. The combined prefabricated retaining wall square pile foundation pit supporting structure and the construction method thereof have the advantages of being safe, short in construction period and low in construction cost.
本发明公开了一种组合预制护壁方桩基坑支护结构及其施工方法，通过将搅拌桩、预制桩、连接钢构件、外挂钢构件和微膨胀混凝土施工形成止水挡土一体的地下护壁，以为基坑提供支护稳定，保证了基坑能够在地下护壁的围蔽范围内快速安全的开挖；并且，利用外挂钢构件的外挂部外挂所述地下室的衬墙，能够取消地下室的衬墙在常规施工时所需的肥槽，减少了基坑的挖填、扩大了地下室的使用面积，并能够减少甚至取消地下室的衬墙植筋，且使得地下护壁能够作为永久结构，无需进行拆除，在施工阶段和使用阶段均能够兼作地下室的外墙，显著的节约了工程造价；本发明具有安全、工期短、工程造价低的优点。
