Double-row pile structure with cored horizontal rotary jet grouting pile on pile body
The invention discloses a double-row pile structure with a cored horizontal rotary jet grouting pile on the pile body, and belongs to the field of building foundation pit engineering. A first crown beam and a second crown beam are respectively arranged at the top ends of the front-row pile and the rear-row pile, and are connected by a connecting beam. During the construction process of the front-row pile and the rear-row pile, first embedded pipes with the same diameters are respectively embedded at the positions with the same depths in the reinforcement cages; after the pile-forming construction is completed, when the foundation pit is excavated to the depth position of the embedded pipes, the horizontal rotary jet grouting pile is constructed along the embedded pipes in the front-row pile body and the rear-row pile body. The rotary jet grouting pile is constructed by rotary jet grouting segment by segment, the positions between the front-row pile and the rear-row pile completely subjected to rotary jet grouting and solidified, and the rotary jet grouting diameter of the tail position is correspondingly increased to form an anchor body with an enlarged head. After the construction of the rotary jet grouting pile completed, before the pile body quality is stable, a prefabricated reinforced concrete square pile is inserted into the pile body, and thereby the double-row pile structure with the cored horizontal rotary jet grouting pile on the pile bodies is formed.
