Because the required precision of reserving hole allowable variation is high, for ensureing precision, the way of taking reinforcing cage 5 to amplify, the processing length and width size of reinforcing cage 5 (or claims reserving hole than prepared screw-bolt hole hole, base concrete bolt slot) all large 20mm of length and width, expand misalignment of axe (allowable variation+reinforcing cage size strengthens 10mm);
Because prepared screw-bolt hole hole is too much, locate the unwrapping wire time for saving reinforcing cage 5, the reinforcing cage 5 processing is determined to different locate modes according to equipment Foundations size; Be less than the equipment Foundations of 1500mm × 1500mm for cross section, reinforcing cage 5 is welded as entirety at the scene, locates like this unwrapping wire and can control according to two central axis of whole bolt hole, saves the unwrapping wire time; Be more than or equal to the equipment Foundations of 1500mm × 1500mm for cross section, same axis reinforcing cage 5 is welded as a whole, and reinforcing cage 5 is located unwrapping wire can pass through two axial line control;
3) the on-the-spot accurately location of reinforcing cage:
Two central axis of method location unwrapping wire take to control to(for) overall reinforcing cage 5, all the other reinforcing cages 5 adopt both direction to observe and position unwrapping wire; Reinforcing cage 5 fixedly take in advance in the time of equipment Foundations bearing platform construction pre-buried Φ 25mm steel bar end on cushion cap; Before equipment Foundations template is installed, reinforcing cage 5 and embedded bar head and reinforcement foundation are welded securely as entirety with Φ 22mm～Φ 25mm reinforcing bar or L50mm × 5mm angle steel 6, check reserved screw center to center distance, hole depth, verticality, qualified when being within the scope of allowable variation;
4) bolt box promotes:
Prepare bolt box lifting appliance, bolt box lifting appliance is arranged on a cabinet frame 7 by 11,2 Chain blocks of 7 and 2 Chain blocks of door cabinet frame (jack);
Base concrete is built complete intensity and is reached after 2.4Mpa, can carry out bolt box lifting work, door cabinet frame 7 is stood in equipment Foundations, by 2 Chain blocks (jack) 11 corresponding 2 circular draw rings 9 that catch on bolt box respectively, adopt the circular draw ring 9 on the balanced elevator bolt box of Chain block (jack), the equilibrium of bolt box entirety is slowly upwards promoted, when lifting, need avoid colliding hole slot concrete suitable for reading, after bolt box is lifted out hole slot, clear up in time and brushing release agent, use in order to secondary.
