Basic inspection: Firstly, the sundries on the foundation should be removed, and a temporary and reliable fence should be erected on the edge; level gauges for measuring elevation, Ф0.5mm steel wire, wire hammer, CK6150 CK6150B CK6160 CNC AUTOMATIC PRECISION METAL LATHE MACHINEink fountain and adjustable brackets for pulling steel wire ropes should be prepared; foundation center given by civil engineering line position, check whether the vertical and horizontal centerlines are vertical.CK6140 CK6150 CK6153E HORIZONTAL FLAT BED CNC LATHE MACHINE After the center line meets the requirements, use a hammer to cast the center position on the foundation embedded part or the foundation edge angle iron frame, and mark it; Research on Vacuum Heat Treatment Technology of Cr12 Steel according to the foundation center line, check the actual position and center deviation of the anchor bolts and each positioning embedded part No more than 2mm, record the inspection results in the installation record; Vacuum heat treatment of 3Cr2W8V steel-aluminum die-casting mold clean the anchor bolts, measure the verticality deviation of the bolt holes should be <L/450; and the elevation of the settlement observation point, and make a record; check the shape and size of the foundation and the shape and size of the hole, which should meet the design requirements; check that the surface of the foundation should be free of defects such as pockmarks, honeycombs, cracks, holes, and exposed ribs.
