h-shaped double-row pile structure provided with core-entraining jet grouting pile
The invention discloses an h-shaped double-row pile structure provided with a core-entraining jet grouting pile, and belongs to the field of building foundation pit engineering. The h-shaped double-row pile structure comprises a plurality of front rows of piles, a plurality of rear rows of piles, the jet grouting pile, a precast reinforced concrete square pile, an expanded-head anchoring body, a top beam I, a top beam II, a top beam III and a connecting beam, wherein the front rows of piles and the rear rows of piles are arranged in parallel and form an h shape; the top beam I, the top beam I and the top beam III are respectively arranged on each front row of pile, each rear row of pile and the jet grouting pile; the top beam I and the top beam II are connected through the connecting beam; the jet grouting pile with a large inclination angle is arranged between the piles in each group of rear rows from the inner side of a pile top platform of each front row of piles; the jet grouting pile is constructed by a sectional jet grouting manner, and the jet grouting diameter of the tail end is correspondingly increased to form the expanded-head anchoring body; after the construction of the jet grouting pile, the precast reinforced concrete square pile is inserted into the jet grouting pile before the mass is stabilized; the jet grouting solidifying body in sectional construction can be closely matched with the earth at the back of the pile and integrally connected with the earth at the back of the pile through a precast reinforced concrete pile.
