Construction method for overlength jet grouting stiffness core combined pile
The invention discloses a construction method for an overlength jet grouting stiffness core combined pile. The construction method includes following steps: (1) determining the vertical and horizontal distribution conditions of high-pressure-bearing water sections and non-high-pressure-bearing water sections according to the geological condition, and determining the quantity and the diameter of jet grouting pile expansion sections in pile bodies of overlength jet grouting piles; (2) performing construction of a plurality of groups of overlength jet grouting piles by employing high-pressure jet grouting drills, and setting the spacing between the plurality of overlength jet grouting piles according to the diameter of the jet grouting pile expansion sections; (3) manufacturing components of pile connectors, assembling and connecting wing plates of I-steels of various unit lengths by employing wing plate connection bolts and wing plate connection boards in the transverse direction, and forming section steel piles in unit lengths; (4) inserting the section steel piles, assembling the section steel piles of various unit lengths via web connection bolts and web connection boards according to the design length of the section steel piles, and accomplishing the construction work of the overlength jet grouting stiffness core combined pile via assembling and inserting; and (5) accomplishing the construction of the jet grouting pile expansion sections and the overlength jet grouting piles.
