H-shaped steel positioning device and positioning method for SMW method pile
This invention discloses an H-beam positioning device and method for SMW (Self-Mixed Mixing) piles. A guide trench is formed in the soil at the top of the SMW pile, with its centerline aligned with the centerline of the SMW pile. The SMW pile includes multiple mixing piles evenly distributed in the soil at the bottom of the guide trench for inserting H-beams. The H-beam positioning device comprises multiple positioning device bodies, each including a positioning frame, at least two markers, and at least two observation points. This invention uses variable-length connecting rods and fixing bolts to connect multiple positioning device bodies into a single unit, accommodating various H-beam insertion methods. The observation points, in conjunction with the markers, monitor the position of the H-beams during insertion, reducing the probability of eccentricity. It eliminates the need to move individual positioning device bodies to the next H-beam insertion point after the current H-beam is completed, thus improving construction efficiency.
