Combined type foundation pit supporting structure with multiple rows of piles
The invention discloses a combined type foundation pit supporting structure with multiple rows of piles. The combined type foundation pit supporting structure comprises a front row of piles, a rear row of piles, jet grouting piles, a prefabricated reinforced concrete square pile, a top beam I, a top beam II, a top beam III, a connecting beam I and a connecting beam II. The top beam I, the top beam II and the top beam IIII are arranged at the top ends of the front row of piles, the top ends of the rear row of piles and the top ends of the jet grouting piles respectively. The top beam I, the top beam II and the top beam III are connected through the connecting beam I and the connecting beam II. The jet grouting piles are constructed in a segmented jet grouting mode. The diameter of a jet-grouted body at the tail end of each jet grouting pile can be correspondingly increased, so that the jet-grouted body forms an expanded head anchoring body. After the jet grouting piles are constructed, the prefabricated reinforced concrete square pile is inserted into the jet grouting piles before the quality of the jet grouting piles are stabilized. According to the combined type supporting structure with the multiple rows of piles, the anti-capsizing performance and the rigidity of a supporting system can be effectively improved, and displacement of pile bodies can be effectively controlled at the later stage of foundation pit excavation process; the combined type foundation pit supporting structure can also serve as a novel deformation control measure used at the later stage of foundation pit excavation.
