Q:The road from top to bottom, followed by 500 thick gravel, 300 thick cement stabilized macadam, 100 thick asphalt. While the gravel bottom elevation and elevation is very close to the top of the rain water, how to prevent the roller crushing rain water pipes?

There is no good way, the bottom of the 500 thick gravel can only be compacted with light rolling equipment, such as frog ram, impact rammer, etc., according to specifications above the pipe top 50 centimeters to use roller mill rolling.

Q:What is the design principle?Experts: how to build a large machine --- roller, the internal structure of its drum (with the brief introduction of the best)? What is the design principle? What is the maximum weight of the drum at present? What kind of traction equipment do you need? Thank you very much.

But no matter what kind of structure, the vibrating wheel is composed of vibrating wheel body, excitation chamber and mounting support part. The vibration chamber is composed of an internal and external bearing seat, a vibration shaft, a vibration bearing, etc. the mounting support part comprises a mounting plate, a shock absorber, a frame bearing, etc..

Q:Sheepsfoot road and a distinction between what work?

Sheepsfoot do stone dam project is still alive.A main work on earth, no difference, and the effect on.

Q:How is the tonnage of the roller machine calculated? Forget to know the answer! Thank you

Compaction performance can not only look at the total weight, but also depends on the amplitude, vibration exciter, steel wheel load a number of factors. The same tonnage, general hydraulic double drive roller than mechanical roller pressure strength.

Q:Why can't we use the tire roller in the modified asphalt road?

The request of the pavement evenness of modified asphalt in laying is' hot 'sticky tire roller through a lot of asphalt will stick in the tire on this will be very troublesome and difficult to remove from the tire and tire with flowers go pavement so as not to have groove pavement and uniform requirements

Q:Vibratory roller pressure and steel roller compacted what is different

You should make the cement stabilized layer of double steel wheel vibratory roller, you should first use vibratory roller vibration compaction, and then do not open vibration to smooth surface. Just do not open the vibration pressure several times, the static pressure only to surface dense, but the bottom is still more loose

Q:Excavators, forklifts, bulldozers, rollers with the same tonnage fight who badly rank

The speed is ranked forklifts, bulldozers, excavators, compactors if real-time battle, long distance attack with reality hit the first row digging machine can,

Q:How many tons of rollers are needed for highway engineering?

At present, 30 tons of construction is not much. At present, the market share is the highest proportion of more than 16 tons of overweight roller. Take the single steel wheel vibratory roller as an example, generally divided into 16 tons, 18 tons, 20 tons, 22 tons and 26 tons, the ZOOMLION still has 25 tons and 27 tons, and from the engineering point of view, it has been able to meet the needs of construction work, five. For users, the higher the tonnage, the higher the price, the more oil consumption, the purchase costs and cost of use also increased accordingly. Now, the largest tonnage of domestic rollers will be 30 tons.

Q:Who will hit the tank and roller collision?

Tomorrow to buy a roller and tanks tried to know

Q:What's the use of this roller? What is the difference between a roller and an ordinary roller?

This is a convex block roller, is adding a layer with a convex block device mounted on the original circular surface of the base, consisting of two semicircle. This roller is mainly used for the compactness of roadbed. In general the main base material is not easy to be smooth when compacting it will be used
