Q:How to prevent sticking wheel on modified asphalt pavement using rubber tyred roller?
Tyre roller is not allowed in modified asphalt pavement!! If forced to use, the only way is that the rubber wheel is opened slowly, followed by three people holding a mop covered with diesel, while walking on the rubber wheel above, this is the only non stick method. But pavement damage is not recommended. The biggest drawback is that the modified asphalt mixture rolling temperature is more than 150, and the tires are also damaged. Therefore, the specification is not allowed. (tyres, tyres, nearly smooth, without lines)
Q:Shantui 22 tons roller fuel consumption per hour is much
Driving habits are not the same, the road conditions are different, traffic jam, load, oil, cold and hot air, whether the running in period / old car is not the same, the fuel consumption is not the same, the general integrated fuel consumption in about 8-10.How much oil means hundreds of kilometers and how much oil?. It's a habit of speaking. Vehicle fuel consumption is generally calculated with 100 km fuel consumption, such as 100 km fuel consumption 10L, meaning 100 kilometers of vehicles traveling, need 10L gasoline.
Q:How many tons are the road rollers in the road? What's the model and how much is it?
Look at what road, county road, following 18, 21, three wheel road, dart 21, one, 24...... The vibration pressure is about 20.................. Prices vary, a manufacturer, a price, three rounds of pressure about two hundred thousand, vibration pressure of more than 20 to more than 30, XCMG road machine is the best, into the factory to buy, do not buy imitation, do not be cheated
Q:What's the inner structure of the roller?
The structural types of vibration wheel are relatively common at present. They are through shaft type (which can be divided into single shaft type, inner and outer sleeve shaft type), welded disc type plate and detachable box type (also called independent vibration chamber).
Q:How do the rollers see dual vibration, single vibration, double drive, single drive, double steel single steel?
Double steel is a finger press. It has two front and rear steel wheels. The single steel refers to the front of the steel wheel, and the back is the rubber wheel. Steel wheels are mainly pressure bed, and some are asphalt. Some are front and rear rubber wheels, which can only be used to press asphalt.Double drive means that the front and rear steel wheels (or rubber wheels) are provided with drive motors on the side, so that the front and rear two motors drive the wheels to roll.
Q:Which is compact for single steel wheel roller and double steel roller?
At present, the double steel wheel is mainly applicable to the compaction of the surface layer or the thinner compaction condition. The base layer or the thicker layer shall be better than the large tonnage single steel wheel.
Q:It is feasible to build a 2 story building. The foundation is compacted by roller
Directly hit the diameter of 90-100cm, deep into the hard mud 1.5m hole, and then steel and cement as a foundation, a pile is better than a roller.
Q:Roller brand at home and abroad
It is worth noting that, in 31, Liugong in China as a representative of the domestic roller production enterprises quickly technology progress in recent years, with the technology gap between foreign brands is narrowing, but we should clearly see that many enterprises are directly to the roller of famous foreign brands to buy a few to remove "Polish" over a period of time, then launch new products, their long term, this copy is the concept of the market test, so the domestic manufacturers should settle down to the real in the research and technology investment funds and energy, like this can do bigger and stronger!
Q:What do you mean by "380/275" in the vibratory force (kN) of vibratory roller?
It means "to".The range of exciting force is between 380 and 275.
Q:Brief introduction of tyre roller
The compacted asphalt mixture conforms to the requirements of compactness and smoothnessSelect reasonable roller combination method and rolling steps to achieve the best results. The asphalt mixture is compacted by a steel cylinder type static roller and a tire roller or a vibratory roller. The number of rollers is determined according to the production site.The compaction of asphalt mixture is carried out in three stages: initial pressure, compound pressure and final pressure (including molding). The roller is rolled at a slow and uniform speed.The initial pressure of asphalt mixture meets the following requirementsThe initial A. pressure roller soosai eng DD-110 in mixture paving after high temperature, and shall not have any time, hair crack, compaction temperature according to the consistency of asphalt, roller type, temperature paving layer thickness, mixture type is determined by the pressure test with test.B. roller is rolled from the outside to the center. The adjacent rolling zone should overlap with 1/3 - 1/2 wheel width. At last, the center part of the rolling road will be compressed at full amplitude. When the edge of the baffle, kerb, shoulder and other files, should be close to the file roller. When the edge without retaining, can mix the edge rake rake slightly high, then the outer wheel roller rolling out 10cm above the edge.
