Commend grouting material manufacturers, equipment standards and the principle of choice - CGM high-strength non-shrinkage grouting material inspection report

grouting grouting material standard of grouting material in order to test the equipment location work, looking for is at ordinary times should be in place after the first equipment benchmark choose good inspection and measuring point.   Benchmark choice should follow the principle of benchmark superposition of grouting material applicable scope, in order to reduce the error of testing work. So-called benchmark superposition is to make cgm1 grouting material model of the selected test datum and the design datum, the processing datum coincidence is one, so that can ensure a smooth and accurate detection of surface, and can avoid the mutual deviation resulting from the above three kinds of datum don't coincide with the device to find is the influence of leveling.       Equipment CGM high-strength non-shrinkage grouting material meet the requirements of the above surface has the following a few kinds roughly: the & # 8195;             1, equipment, the main face 2, support the sliding parts of guide surface 3, the rotation axis of mating surface or 4, equipment should be the main outline of horizontal or vertical or center line 5, the equipment on the surface of the machining accuracy is relatively high slurry, etc.       Site choice, should follow the principle of 'fewer but better', every measuring point is selected representative (should be enough Can represent his plane or line) The minimum error, should be able to ensure the installation. Normally, for rigid larger equipment, can reduce the number of measuring points, and the easy deformation of the equipment, the measuring point should be appropriately increased, in addition, usually on both sides of the space should not be greater than 6 m, and in the place where may cause greater error, so as to ensure the accuracy of adjustment.       Measuring point is selected, available tags indicating its location, in order to find timing is conducted on these locations.
