Before rolling, the thickness, flatness and water content of the loose layer should be checked to meet the requirements before rolling. Compaction should be based on the field compaction test to provide the thickness of loose piles and control compaction times. If the control of the compaction of more than 10 times, should consider reducing the thickness of the fill layer. After passing the compaction test can be transferred to the next process. Unqualified office should be done after the make-up test, has been qualified so far. Highway and a road subgrade filling compaction should use vibration roller or 35 ~ 50t tire roller. When using vibration roller rolling, the first pass should not vibrate static pressure, and then the first slow after the fast vibration from strong vibration to strong vibration. The rolling speed of the various rollers should be slow and the maximum speed should not exceed 4km / h; the straight line segment from the both sides to the middle, the small radius curve from the inside to the outside, the vertical and forward; Vibration roller generally overlap 0.4 ~ 0.5m. For three-wheel roller generally overlap the rear wheel width of 1/2, before and after the adjacent two sections (rolling section before the formation of the pre-compression section and the subsequent inspection section) Overlap 1.0 ~ 1.5m. Should be no leakage pressure, no dead ends, to ensure uniform rolling. The use of rammer compaction, the first pass of the ramming should be close, if there is a gap, it shall not be greater than 15cm, times the ramming bit pressure should be pressed in the first pass of the gap, so continuous consolidation until the required degree of compaction. ?Different grades of light diesel oil, because of their performance indicators in addition to the condensate point, are basically the same, so the oil unit in the case of insufficient containers can be mixed use, does not affect its quality, but at this time must be the highest freezing point Of diesel, as the use of the benchmark.Otherwise, will not be suitable for the local ambient temperature, so that the diesel engine can not work properly. electric soil compactor supplier
