Prepare construction organization design or special construction plan
Prepare equipment entry plans, plan for the use of resources such as labor, materials, and equipment, and organize them in an orderly manner.
On-site facilities should have starting conditions
Unpacking the device
When the machinery and equipment are unpacked, the construction company, construction unit, supervision unit, and supplier
Box number, box number and packaging
Equipment names, specifications and models, important parts and components also need to be checked and accepted according to quality standards
Random technical documents (such as instructions for use, certificates of compliance, packing lists, etc.) and special tools
Whether there is a defect, whether the surface is damaged or rusted
Other matters that need to be recorded
Basic measurement line
Set baselines and benchmarks
The construction unit that undertakes the civil engineering works shall hand over the measurement network points, including the crucial main axis, together with the transfer of the factory building and the basic conditions.
in principle
Easy to install and test
Helps to maintain without being destroyed
Sculpted clearly and easily
Claim
Prior to the placement of machinery and equipment, according to the layout of the process and according to the measurement control network or related building axis, edge line, elevation line, delineate the installation of the baseline and reference point
For mechanical equipment that has mechanical connection with other equipment, a common installation reference line and reference point should be designated
For mechanical devices that have no mechanical connection with other devices, the allowable deviation of the mounting base line for locating the base surface, line or point is ±20mm, and the allowable deviation from the mounting reference point is -10～+20mm.
For mechanical equipment that has mechanical connection with other equipment, the allowable deviation of the positioning base surface, line or point from the installation reference line is ±2mm, and the allowable deviation from the installation reference point is ±1mm.
Permanent baseline and benchmark
Longer installation periods and production inspections require long-term retention of baselines and benchmarks, permanent centered targets and permanent reference points
