1. One-time embedding method: When pouring concrete, embed the anchor bolts. When the tower is controlled by the overturning, the anchor bolt should adopt the one-time embedding method. 2. Reserved hole method: the equipment is in place, the hole is cleaned, the anchor bolt is placed in the hole, and the equipment is positioned and corrected, and then the non-shrinking fine stone concrete higher than the original foundation is used for watering, tamping and compacting. . The distance from the center of the anchor bolt to the edge of the foundation shall not be less than 2d (d is the diameter of the anchor bolt), and shall not be less than 15mm (not less than 10mm when d≤20), not less than half of the width of the anchor plate. Add 50mm. When the above requirements are not met, appropriate measures should be taken to strengthen them. The diameter of the anchor bolts used for the structure should not be less than 20mm. When subjected to earthquakes, double nuts should be used, or other measures to prevent loosening should be used, but the anchor bolts should be anchored for 5 days longer than the non-seismic anchor lengths.
