Q:Why should we use the rubber tyred roller in the construction of the asphalt pavement?
At present, the latter two are widely used in construction.The following is a steel wheel roller, which is in front of the paver. The following table shows two rubber tyred rollers. Roller's purpose: 1. to achieve the required density (usually controlled by compaction); 2. press out the smooth surface.General compaction includes initial pressure, re pressure and final pressure. The final pressure is to remove the traces of rollers, the road is kept smooth, generally can not be omitted, and the use of steel wheel roller. If the initial pressure can meet the density requirements, there is no need to re pressure, but generally still maintain these three steps.
Q:What are the tonnage of the rubber tyred rollers?
1. rubber tyred roller has 16 tons, 20 tons, 26 tons, 25 tons, 26 tons, 30 tons and so on.2. tyre roller is a kind of machine which is used for compacting the road by a plurality of pneumatic tyres. The roller of tyre roller adopts pneumatic tyres, usually 3~5 front wheels and 4~6 rear wheels. If the change of inflation pressure can change the ground pressure, the range of pressure regulation is 0.11 ~ 1.05 mpa. The tire roller adopts hydraulic, hydraulic or mechanical transmission system, single shaft or full axle drive, wide base tire, articulated frame structure, three point support. Compaction process has the role of rubbing, so that the compaction layer particles are not damaged and embedded, homogeneous and dense. Good maneuverability, fast speed (up to 25 km / h).
Q:Roller operation method
The rolling action of 2 DD-110 amplitude and frequency selection of road roller mainly depends on the pressure wheel line pressure, different pressure line selection, and with the paving layer with stone strength and compacted should reach the bearing capacity and. Table 1 shows the strength of the stone and the required line pressure of the roller. Table 2 shows the required line pressure values for several main materials. Because the DD-110 roller has dual frequency 8 amplitude, greatly broaden the scope of its use in the work, can work in a variety of ways, i.e. a variety of line pressure, and pressure line can pass through the table 3 provides data and combined with the formula (1) to calculate the pressure machine under the condition of the road line pressure. The conversion of DD-110 operation mode is quite simple and quick, and the reasonable selection of visual material properties, compaction thickness and other indexes (Tables 1 and 2), therefore, has a wide range of application.
Q:Is the roller on the road?
1. Roller belongs to construction machinery2, non working conditions should be prohibited on the road (except because of construction transitions)
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:The impact roller has high production efficiency
4. the thickness of each filling is 800~1200 mm.5., the project benefit is ten times of other equipments.
Q:Basic parameters of YZ22G vibratory roller
The Y in YZ18 stands for the phonetic abbreviation of the press of the rollerZ stands for vibration as a phonetic abbreviation18 representative work is when the car weight is filled with water, oil and a 100KG driving hand car weight is 18 tonsYZ20C in front of YZ20 means the same as above.
Q:What is the Jingyinshuangzi roller brainwashing and three tragedies to sing the song?
The prisoner series, well, len Rin is the prisoner is patient, they through the paper plane communication, Rin's father found to go to len the plane tore, len played Rin's dad angry... Finally, len went into the gas chamber and Rin died.
Q:What's that round thing in front of the roller? emergency
Vibratory steel wheel for roller.31 roller (SSR200AC-8, SSR220AC-8) for hydraulic type, but it uses the country's three high-power engines, and start without impact, the engine without instantaneous fuel consumption.
Q:What documents do I need to open the road roller?
1, roller operation certificate 2, yes, 3, own registration examination hundreds of pieces, into the training course, then forget it
