Luoyang road roller is a common equipment among compressors. It is flexible and convenient. It can also be used for the compression and smoothing of ditch foundations, roads, and stadiums, and the compression of asphalt surfaces. Equipment with excellent performance and easy operation.

What are the precautions when operating a road roller?

1. The operation method is in place

The first is to avoid prolonged overloading. When the roller is working on difficult roads and sites, if smoke is detected, it should be lowered immediately. The handover of road operations should be carried out slowly and the operating regulations should be strictly followed. No running sound is detected while the machine is running. After the running sound stops, you can start over to solve the problem. All interval adjustments should be checked regularly.

2. New execution place

Many people think that grinding is a waste of time and oil, which is indeed "uneconomical". Some people think that just running at high speed and idling for two or three hours is enough. According to experts, grinding is a gradual process, and Luoyang road roller rollers should start with low speed, low speed gear, low load, high speed strengthening, and high load.

3. Maintenance in situ

Due to the poor working environment of Luoyang road rollers, maintenance is particularly important. Friction, vibration, grease, and water on parts are inevitable during work, so worn parts, loose joints, corrosion, and aging conditions will cause equipment deterioration.

What factors can affect the construction quality of Luoyang road rollers

1. Different types of soil have different compression properties. In the case of filling soil, gravel soil, sandy soil, and sandy soil are suitable. This kind of soil is hard, has sufficient stability and low sinking. What is difficult to harden is clay. In a wet state, this kind of soil is unstable, has a greater water content than other soils, and has a lower dry density. However, hard clay still has good impermeability.

2. Moisture content

Moisture content has a great influence on the extrusion effect, and the moisture content must be controlled during trench backfilling or roadbed compression. The moisture content is strictly controlled within 2% of the moisture content. In this state of the soil, the gravity between the soil is small, the film is thick, and there is lubrication. External compression can easily make the soil eggs move relative to each other, and the compression effect is good. When the soil moisture content is too high, free water will be produced in the gaps, and the compression function of the small roller cannot discharge gas. Part of the compression function is offset by the free water, and the effective pressure is reduced, and the compression effect is reduced. The water content is small and the gravity between the soil is high. The dry weight is great, but its strength may be higher than the moisture content. But at this time the density is low and there are many holes. When it comes to the catcher, the intensity drops sharply.

3. Vibration frequency and amplitude

Vibration frequency and amplitude are important performance parameters for the compaction work of vibratory rollers. The vibration frequency is the number of times the vibrating wheel vibrates per unit time (HZ). Amplitude is the height (mm) of the vibrating wheel from the ground when vibrating. The amplitude parameter is usually the indicator name Amplitude. Assuming vibration on a perfectly elastic surface, the vibrating wheel hangs completely freely at ground level. Actual vibration pressure real-time actual amplitude is usually slightly larger than the nominal amplitude. The vibration frequency is high and the surface flatness of the compression layer is good. The amplitude is very large, and the impact force acting on the compression layer is very large. According to the work content, the vibration frequency and amplitude must be coordinated with each other to achieve the compression effect.

4. Rolling layer thickness and rolling times

The speed of compression also affects the compression effect. When the degree of compression is required and the soil layer is thick, the driving speed will be slower. Rolling should start slowly, and as the soil layer becomes denser, the speed will gradually increase. At the beginning, the soil is relatively loose and has low strength, so you need to press lightly at first, and gradually increase the pressure as the density of the soil increases. Therefore, while advancing the road material, mechanical vehicles should be evenly distributed across the entire width of the embankment in an effort to ensure uniform preloading of the fill.
