1. Rectification of squareness ratio at the end of steel sheet pile

Cut the end of the steel sheet pile with oxyacetylene to keep it perpendicular to the axis, and then use a grinding wheel to smooth and repair the cut surface. When the amount of dressing is not large, directly use the grinding wheel to repair.

2. Deflection correction of steel sheet pile

The bending correction of the steel sheet pile is to fix the two ends of the bending section of the steel sheet pile on the supporting point, and use the jack set on the gantry top beam to perform the cold bending correction on the convex part of the steel sheet pile; the lateral bending correction is performed in a special On the correction platform, fix both ends of the bending section of the steel sheet pile on the support of the correction platform. Set a jack at a certain distance on the correction platform on the side of the bending section of the steel sheet pile.

3. Steel sheet pile distortion correction

Depending on the distortion of the U-shaped steel sheet pile, the method in (2) can be used to correct it.

4. Correction of local deformation of the section of the steel sheet pile

The local deformation of the steel sheet pile is corrected by the combination of jack pressing, sledge hammer percussion and oxyacetylene flame heat drying.

5. Deformation correction of steel sheet pile lock

Standard steel sheet piles are used as the lock shaping mould, and the slow-speed hoist is used for pulling adjustment treatment or the oxyacetylene flame heat drying and sledgehammer hitting the mould propulsion method for straightening treatment.
