Q:Who knows, a long work, Xiagong, Liugong roller defect?

Q:How often do rubber tyred rollers maintain?
3 windshield wiper and washing check / wiper position / wear check;4. Visually inspect the outside of the body, the body under the protection of parts, pipes / hoses (exhaust - fuel lines - brake lines), rubber parts (dust cover, bushings, bushings, etc.) status;5, visual inspection of various control belt conditions;
Q:Rules for the operation of rollers

In turn, including articulated vibratory roller in small turning round rolling, prohibited the use of fast file.
Q:What is the cause of soil cracking when subgrade is pressed by subgrade?
When the moisture content of backfill material is too large, cracking occurs in the course of pressing, and it will become loess when it is serious. The optimum moisture content of backfill is between 9% and 11%.
Q:When using 20T heavy vibratory roller, what is the backfill thickness per layer?
2, subgrade backfill using heavy roller, in order to ensure backfill quality. The construction of subgrade soil subgrade must be layered backfilling, each layer backfilling thickness is less than 30cm, roller with 18-20T times the number of not less than four times, with cutting ring check its density to meet the design requirements must be.3, after the roadbed forming, should be central line, elevation, vertical and horizontal gradient test, qualified immediately after maintenance, after the expiration of the maintenance report submitted to the quality inspection department for acceptance testing.
