- Q:XCMG vibration roller 14J and 14JC what is the difference?
- As for where there is a difference, you call Xugong after consultation. Not used, basically unclear, or go to their official website to find out, see if there is any?. Hope to help you.
- Q:Is the roller on the road?
- 4, if the roller running normally, and through the municipal engineering administrative department approval, because the transition needs no violation driving. It is only after the accident scene has been identified that the conclusion can be reached.
- Q:Roller operation method
- In the following, the data and performance of DD-110 vibratory roller in highway construction are analyzed. 1 DD-110 double drive double vibration effect of 1.1 double drive active material is the pressure force of wheel H '=H and R' R '=R, vertical force on the compacted material, while the level of H' is the material driving force to the roller to move in the opposite direction, the mobile will be the driving wheel has been compaction of material resistance, the granular materials are pressed in high pressure moving close to the vertical line of the roller interval, thus forming the wavy surface of the driving wheel is not before, the compactness of the surface material will be fairly flat. Because the DD-110 roller adopts two wheel drive structure, with the excellent performance of compaction, does not produce the phenomenon of wave, so as to ensure the smoothness of pavement compaction, so also will the drive roller is called non corrugated roller, which is a rigid index must reach the highway. 1.2 double vibration vibration make the internal friction material pressure was dramatically reduced, shear strength decreased, so the compressive resistance is very small, very easy to be out of gas pressure in the material and liquid, which are embedded in crowded compacted. Because DD-110 has the function of double wheel vibration, the compacting efficiency can be greatly improved in the process of compaction, and the asphalt pavement is more favorable for the forming of the road surface and the quality of the construction.
- Q:Rules for the operation of rollers
- 10. Other operating requirements shall comply with the requirements of the hydrostatic roller.No matter whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt binding layer must be sprayed to avoid sliding when the mixture is rolled.No matter whether it is uphill rolling or downhill rolling, the driving wheel of the roller should be behind. It has the following advantages: uphill, the driving force behind the driving wheel can withstand ramp and machine provided by their own, while the front wheels were initially on compaction, to withstand the large shear force driving wheel produces; downhill, impact roller weight generated by the driving wheel brake offset, capacity only by the mixture compacted to support the front wheel driving wheel produces shear stress.When rolling uphill, the start, stop and acceleration of the roller must be stable, so that the speed is too high or too low.Before the uphill rolling, the mixture should be cooled to the required low limit temperature, and then static preloading shall be applied. When the mixture temperature drops to the lower limit (120 DEG C), the vibratory compaction will be adopted.The sudden change of speed and braking should be avoided in downhill rolling.The slope is very steep downhill in rolling case, should use light roller pre pressure, followed by heavy rollers or vibratory compaction.
- Q:What types of rollers are there?
- The roller type very many, small hand roller, roller, vibratory roller, Jining Long Xiao Machinery Co. Ltd. roller variety, customer visits to the factory, the company continued to develop the production of qualified products to meet market demand, customer service service needs of national construction. Where is the project, where there are long Xiao products.
- Q:What kind of vibratory roller is used in roller compacted concrete construction?
- First of all, roller used vibratory roller.Then。 Concrete rolling, according to the thickness of different layers, the use of different performance vibration roller (also known as vibratory roller)
- Q:How does the municipal asphalt pavement budget do not have a wheeled roller?
- you can audit and said, don't fixed costs, change according to the market price of Jixietaiban, and don't forget the large machinery import charges.
- Q:How about a beginner? Drive a roller
- In accordance with the operation of the wheels and the road along the road of slowly fine-tuning, go back to see just the pressure line as a reference, a large operation is more simple, first out of a straight line, then straight to the reference.
- Q:What's the difference between a three wheel roller and a two wheel roller?
- Three roller is the static compaction, without vibration function, used for compaction of embankment or base, two roller generally called double drum vibratory roller, roller tonnage than three small tonnage, mainly used for oil pressure, the asphalt concrete, with vibration function, the upper two wheels a water tank, can go on wheels to prevent water roller compacted asphalt concrete glued to the wheels.
- Q:Then the grass-roots construction to the stability layer, including two ash macadam stage, will use 21T iron three times repeatedly rolling the road. Excuse me, iron three rounds again in this process, the role and vibration roller what is the difference?
- First of all, to clear the use of vibratory roller and a roller.In general, vibratory roller used for rolled earth rock subgrade, because of its quality, coupled with the vibration force, can increase the rolling depth, but also can make the earth subgrade compacted in a certain depth range, reduce the gap in the embankment of roadbed, compaction depth generally 20 to 30 cm is appropriate. Different grades of highway there are different requirements.The smooth wheel roller generally used two ash macadam and other basic roller compaction or other rolling road.
