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:The vibratory roller is rolled back and forth several times at a time
when the actual construction is not calculated, the number of rolling, as long as the road roller can not stop
Q:Difference between single steel wheel roller and double steel roller
The main difference between the three is the use of parts and the use of different procedures.
Q:What are the specific types of Compactors? What is the function of each? What is the difference?
Here I will not say too much! Because Chinese electromechanical data network is quite comprehensive! Pure non handwritten copy and paste to forget to hope you can have a more in-depth understanding of!
Q:The width of the road is four meters. The roller runs for half an hour. It can press a large area of road
Solution: it is known that a roller runs 25 meters per minute and the width of the roller is =4 meters,Get the roller area per minute of the roller= running length per minute * width of road=25 * 4=100 square metersAnd roller drive for half an hour, half an hour =30 minutes,Roller must be driven for half an hour= pressing area per minute * road time=100 * 30=3000 square metersAnswer: roller run for half an hour, can press 3000 square meters of road.
Q:Let me have some never played roller! 10 years 22 tons for 22W mountain people think? What are the disadvantages of this roller?
Shantui only bulldozers can also be done, not others ah, push the loader with a roller should know, the best in the garbage.
Q:The asphalt pavement here is divided into three layers, the two layer with rubber tire roller for rolling, the surface layer is needed for the rubber roller, wherein the two layer is below AC, the top layer is SMA series.
So the asphalt pavement construction specification said.There is waterproof good, mainly depends on grading
Q:Excavators, forklifts, bulldozers, rollers with the same tonnage fight who badly rank
when other machine ran first and then driving the main digging sub floor, kill the driver, do not close machine line, so this is a boring the problem is driving technology, the two is to have strategic thinking, the three is not afraid of death.
Q:What are the benefits of using it?
The tire roller adopts hydraulic, hydraulic or mechanical transmission system, single axis or shaft drive, wide base tire hinge the frame is supported by three points.
Q:slow pressing, high frequency and low amplitude". How do you understand the low amplitude behind it? Thank you
Low amplitude is the amplitude of the theory of vibratory amplitude level, a greater impact on the basis of asphalt road, because the base layer has good compaction, the compaction is to improve asphalt surface layer compaction, compaction and does not affect the base layer damage, so the compaction of high frequency and low amplitude only.
