Q:XCMG 303 tire roller engine type
Towed vibratory compaction can effectively all kinds of soil and rock fill, suitable for modern highways, airports, seaports, embankment, dam, railway and mining engineering construction in the roller device many bump pressure roller. Due to the bump like sheep foot so called sheep foot roller, sheep foot roller. The shape of the convex block is a sheep foot shape, a cylindrical shape, a square column shape, etc.. The roller shaft is supported on the bearing of the traction frame and expands the application range. Can be filled with water, sand or sand to increase the weight of rolling drum. Comb scraping plate is arranged below the frame drum before and after, to clear the bump between sticky mud block. Towed by a tractor dragging sheep foot roller. Self-propelled kneading or tamping roller. Kneading unit pressure, the filling evenly, a tamping effect, degree of compaction, especially for hard clay, suitable for compacted clayey soil and gravel layer. Especially for hard clay, the convex block has stirring, kneading and tamping action, there is tamping effect, so that the packing is even, the upper and lower layer bonding good, avoid delamination. Widely used in subgrade, cushion and dam compaction. The self-propelled kneading drum can also be installed in the vibration device, made of vibrating compaction roller, the vibration force increases the compaction effect, can be filled with water, sand or sand to increase the weight of rolling drum. Expand the scope of use. The main technical parameters of the machine for kneading weight and unit pressure. Due to compaction bump shape so that the 1. sheep foot kneading on roads and railways, dams, airports, factories, residential buildings. 2. cement plant waste, ash, coal and other bulk stacking site compaction. 3. compaction of earth and stone with relatively wide water content. 4. compaction of rock, clay, and expansive soil. 5.. Flame retardant compaction of opencast coal seam.
Q:How many types of rollers are there?
A roller has large tonnage, medium tonnage, and small tonnage.
Q:How do the rollers see dual vibration, single vibration, double drive, single drive, double steel single steel?
There is only one drive motor for single drive.Double vibration means that a vibration motor is arranged on the side of the front and rear two steel wheels, and the vibration motor can drive the eccentric shaft inside the steel wheel to generate centrifugal force so as to realize vibration compaction. Single vibration is that there is only one vibration motor (in front or rear wheels).
Q:What are the tonnage of rollers?
The amplitude of the same premise simply: imported 14 tons of original Dynapac roller is enough, influence Dynapac 19 tons of single drumroller depth is 1.5 meters. If 30cm can also affect the domestic 20 tons roller estimation however, do not know a test section. If you want to rent the equipment Dynapac compaction work can be found in Xuzhou Luqiao Gongli machinery limited company, they have more than 20 sets of dynapad single drumroller can be rented.
Q:Road engineering, soil compaction and road roller / Diesel / what is the difference between the two rolling?
To meet the requirements of doing subbase filling and rolling; including earthwork backfilling, bulldozer, layered rolling to meet the design requirements of the degree of compaction, the smoothness of the road not good.No double counting, for example, road subgrade backfill, backfill compacted well, if you want to do is road subbase, rolling, if it is not just the general fill roadbed RCC.
Q:Basic parameters of YZ22G vibratory roller
I mean by myself that I can walkSelf vibration means that you can walk and vibrateA usually refers to the static roller, now mostly in the light of steel wheel, wheel vibration can not.
Q:Urgent urgent! The road roller does not travel 20
I used to open digging at the site, I know the mechanical crawler excavator is not directly on the road. There should be no problem with the rollers. The vibration and the iron wheels are all straight to the road!
Q:Building construction, taking vibratory compactor as an example, illustrates the method of compaction Matters to be attended to?
Roller static pressure 2 times. The overlap wheel width is 1/3 to 1/4, and the rolling speed is 25 to 30m / min. Then crush it 6~8 times with shock. Overlapping rear wheel 1/2, rolling speed 30 ~ 50M / min.
Q:Asphalt mixture pressure should give priority to the heavy duty tire roller compaction,
As for modified asphalt mixture are generally due to discontinuous gradation, rub tire roller will make the coarse aggregate surface, causing structural depth decreases, and even bleeding. So generally use vibratory roller is better.
Q:Xugong has 22 tons of rollers weighing several tons
22 tons is the nominal weight of the factory, the actual weight is about 21.5 tons. Generally speaking, the weight of more than 21 tons, even 22 tons. Because I am a second-hand roller, I still know about this. (Shanghai the Great Wall second-hand construction machinery company)
