| Zusammenfassung: | The utility model relates to a concrete supporting structure, in particular to a concrete structure for deep foundation pit supporting. The concrete structure consists of a plurality of adjacent portal rigid frames which are connected through a ring reinforced concrete slab at the top of the concrete structure. Each portal rigid frame consists of a front-row concrete grouted pile and a rear-row concrete grouted pile which are rigidly connected through a reinforced concrete sleeper beam and a reinforced concrete haunching node. A three-axis mixed cement-soil pile is arranged in each portal rigid frame. Spiral stirrup densification zones are arranged on the front-row concrete grouted piles and the rear-row concrete grouted piles. The concrete structure for deep foundation pit supporting has the advantages that the construction gap time is reduced, the construction is convenient to conduct and the manufacturing cost is saved. |
