If the fill section construction, the junction of the first two parts should fill 1: 1 gradient layered nothing intervened, stratified layers each adapter, which will lap length of not less than 2 meters. Road bed on the face should be filled within the range of 30-50 cm to meet the requirements of the road bed layered with earth and rock compaction maximum filler particle diameter not greater than 10 cm. Backfilled pit 18T using 5 meters above the vibrating roller strong shaking, strong shook range not less than 10 meters in the way group outside line.Earth base design height and length side ditch after the use of construction waste backfill or prime ground shaking. 11, subgrade compaction after strong shaking must meet in the attached drawing "earth embankment design and construction technical requirements" Fill the lot according to design requirements leveling compaction, should be ready before the start of construction survey work, including: middle wire measuring appropriate standard point retest and cross check and supplementary, additional points can fulfill the standard requirements.
