Support system for ultra-deep foundation pit
The invention relates to a support system for an ultra-deep foundation pit. The support system for the ultra-deep foundation pit is characterized in that the support system comprises a single-row three-axis deep mixing pile water-stop curtain, a plurality of cast-in-situ bored piles and a plurality of steel stand columns; the single-row three-axis deep mixing pile water-stop curtain is lower than the natural ground and arranged around the foundation pit in an enclosure mode; the cast-in-situ bored piles are sequentially arranged in the portion, on the inner side of the single-row three-axis deep mixing pile water-stop curtain, of the foundation pit at intervals; the steel stand columns are arranged in the portions, on the inner sides of the cast-in-situ bored piles, of the foundation pit; the tops of the cast-in-situ bored piles are sequentially connected in a pulled mode through reinforced concrete top beams, and reinforced concrete enclosure purlins are arranged on the inner sides of the cast-in-situ bored piles around the foundation pit and not located at the height positions of all underground floor slabs; the inner sides of the reinforced concrete enclosure purlins are connected in a pulled mode through a plurality of reinforced concrete enclosure purlin beams supported on the steel stand columns; the reinforced concrete enclosure purlin beams and the reinforced concrete enclosure purlins are in pulled connection in a latticed mode through a plurality of sets of reinforced concrete inner supports; tamping plain concrete is arranged at the bottoms of the cast-in-situ bored piles inwards; a base plate is laid on the foundation pit and located on the inner side of the tamping plain concrete, and one or more post-cast strips with replacement supports are arranged on the base plate.
