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.
Q:When the new high-speed road roller is used to press the road surface, it will cause cracks in the surrounding houses. What are the criteria for compensation? How many meters away from the subgrade is the range of compensation?
In this case, the local government can be reflected in the situation, and for the corresponding losses caused by residents, or compensation. The general compensation is calculated according to the area of the residents.
Q:Is there any difference between vibratory roller and vibratory roller?
It's the same rollerCompacting capacity of vibratory roller = mechanical weight + exciting force (vibratory force of vibratory wheel mechanical vibration)Compared to the previous self weight roller, the volume and weight have been reduced, but the compaction effect has been improved obviously.
Q:Where are the rollers attached to the rollers?
Upstairs said that the diesel engine oil, generally can find. Inside the reducer roller and the gear oil, is a heavy load gear oil, the Great Wall, Kunlun, Mobil, Shell and other series, such as the Shell VG150 heavy load gear oil, Mobil 629 series, the Shell VG150 gear oil is prescribed brand models of Sany products, and in the steel wheel and driving speed reducer vibration wheel, Shell VG140 gear oil filling in single drumroller rear axle reducer. Other brands of roller gear oils may have different brands and models. The steel wheel driving speed reducer addition: two is 90 degrees, and put the oil nut, screw it loose, start the engine running, one oil discharge outlet vertical reducer gear oil released after walking again, the two oil outlet of a vertical and a horizontal from the beginning, at the top of the filler filling gear oil, until the level direction of the oil port gear oil out of date. Refueling capacity of about 4.5L. Vibration wheel gear oil additive: three a 120 degree uniform oil adding and discharging port, oil discharge method ibid, to a vertical oil port down oil, after the oil discharge screw on a rotating steel wheel nut, make an oil outlet straight up, another loose oil the mouth slanting down (because the three port is 120 degrees.), from the mouth to the oil filling oil, until the oil port oblique gear oil out of date. Refueling capacity of about 11.5L. After oil addition: gear reducer bridge observation hole loosen nut central, loosen the direction by the reducer and put the oil nut oil (rear axle oil adding and discharging nut good judgment, nut at the top of a concave circular), and then go nuts loosen upper, middle gear oil to observe the outflow of oil can. Refueling capacity of about 18L. The above for Sany roller filling gear oil method and dosage, other brand roller may be different, but should be very similar, hope to help LZ.
Q:How many tons are there in the maximum roller?
Static roller selection should also consider the large tonnage products, especially for the construction of the user only static roller, in order to improve the construction efficiency and compaction quality, the tonnage is best not less than 15t, after adding sand weight after weight should be more than 18t.Because of the existence of elastic deformation during the rolling process, the tire roller can play a role in kneading the compacted material, and can make the asphalt and other paving materials sealed and reduce the leakage of the pavement under the rain. According to the requirements of the new national standard "construction and acceptance of asphalt pavement" in our country, it is necessary to popularize and apply the large tonnage tire roller to re load asphalt composite paving.
Q:The rollers are divided into several types
The routine use: single steel wheel used in roadbed, double steel wheel and rubber wheel. But according to the construction in the oil surface different processes and materials, double steel wheel and the rubber wheel will be used in the roadbed.
Q:How many rollers are there in the roller?
Single wheel mechanical rear wheel drive.The single steel wheel is fully hydraulic and can drive both front and rear.
Q:How about a Luoyang road roller?
Recommended to buy well-known trademarks, such as mountain push, Xugong roller, quality and after-sales service better.
Q:Roller monthly rent 20What is the monthly rent for the 20 ton vibratory compactor in Anhui?
My view is Xugong, Shandong Shantui machine reputation is also good, you can rent what type of machine, hydraulic cylinder wheel vibration of the rent of 12000 yuan, 17000 yuan in rent type, double cylinder wheel rent of 40000 yuan, the price is in season, the off-season would go bad. I'm also thinking of buying a roller with a rubber wheel. I hope we can talk to each other
Q:What is the difference between roller vibration and static pressure?.
Vibratory roller is to use its own gravity and vibration compaction of various construction and road construction materials. In highway construction, vibratory roller is suitable for compaction of various non cohesive soil, crushed stone, crushed stone mixture and various asphalt concrete, and is widely used.Static pressure: 1 tons roller weight 1 tons, static pressure strength is 1 tonsVibration: 1 tons roller, vibration force 2.5 tons, vibration pressure strength 1+2.5=3.5 tons.The working principle of vibratory roller1, the emergence of vibration - mass eccentric + rotationIn the picture, the big circle is a vibrating wheel, and the blue green is an eccentric vibrator. When running at high speed, the eccentric steel force drives the big steel wheel to vibrate together, and generates exciting force.
