In areas with complex construction conditions, whether it is rolling the road or compacting the foundation, the ground must be leveled first, so that it is easier for machines such as rollers to carry out the following compaction process. For this leveling work, a practical mechanical equipment came into being, which is the grader/Niveleuse/Motoniveladora.
1. What is a motor grader/Niveleuse/Motoniveladora?
A motor Niveleuse is a high-speed, efficient, high-precision and multi-purpose earth-moving machine that uses a scraper to level the ground. The scraper is installed between the front and rear axles of the machine and can be raised and lowered, tilted, rotated and extended. It is flexible and accurate in movement, easy to operate, and can level the site with high precision.
2. What is the function of a Motoniveladora?¿Cuál es la función de una Motoniveladora?
Motor Motoniveladora are mainly used for constructing roadbeds and pavements, building slopes, and digging ditches. They can also be used to mix road mixtures, remove snow, push bulk materials, and maintain dirt and gravel roads.
3. What are the applications of graders in engineering?
1) Roadbed leveling for road projects: In road construction, it is used to trim the surface of the roadbed to ensure that the flatness of the base meets the design requirements. Slope trimming: Adjust the slope angle of the embankment or cutting to form a regular slope. Mixing materials: Mix soil and stabilizers (such as lime and cement) with a scraper to improve the stability of the roadbed. Paving assistance: Level the base before paving asphalt or concrete to improve the uniformity of the road surface. Snow maintenance: Clear snow or compact the snow layer to ensure road traffic in winter.
2) Construction site leveling: cleaning the construction site and leveling the ground for subsequent construction (such as foundation and pile foundation work). Foundation pit backfilling: assisting in backfilling and compacting the soil to ensure uniform filling.
3) Water conservancy project channel excavation: trim the bottom and slope of irrigation or drainage channels. Dam construction: compact and trim the surface of the dam to enhance the structural stability.
4) Mine Engineering Road Maintenance in Mining Areas: Keep the transportation roads in mining areas smooth and improve the traffic efficiency of vehicles. Waste dump area preparation: level the waste accumulation area to facilitate subsequent reclamation or ecological restoration.
5) Agriculture and land consolidation Farmland reconstruction: leveling uneven farmland, optimizing irrigation and mechanized farming conditions. Terracing: creating terraces on sloping land to reduce soil erosion.
6) Airport construction runway construction: Accurately trim the runway base to ensure high flatness to meet take-off and landing requirements. Apron leveling: Processing the base before laying large areas of concrete or asphalt.
7) Environmental governance Contaminated site remediation: Spread covering materials (such as impermeable membranes, clean soil) to isolate pollutants. Landfill covering: Level and compact the covering layer to reduce environmental pollution risks.
8) Municipal engineering park and square construction: shaping the terrain or repairing the foundation of the green belt. Pipeline trench backfilling: assisting in the backfilling and compaction of earthwork after the buried pipeline.
9) Special application of loose gravel road treatment: quickly leveling temporary roads in deserts or gravel areas. Emergency rescue: cleaning up the site after a disaster and restoring road traffic capacity.
4. What are the precautions when driving a grader?
1) When operating, the blade or ripper must be lowered after the machine starts, so that the load can be added slowly. Otherwise, it will cause difficulty in starting and even damage the machine parts. In order to avoid excessive idling, the blade or ripper can be lowered to a position close to the ground before starting.
2) Try to use a larger rotation angle so that the blade has a larger cutting pressure per unit length.
3) When the soil is hard, a smaller shovel angle can be used to reduce cutting resistance; if you want to improve the leveling accuracy or material and effect, the shovel angle can be slightly increased.
4) The blade rotation angle, soil scraping angle and side inclination (outboard inclination) must be adjusted when the machine is parked, but the left and right extension of the blade can be carried out during use.
5) When the blade is raised or lowered, the left and right lifting levers should be moved gradually, but do not adjust too much. Otherwise, the machine will be overloaded and slip, causing the working surface to be wavy or uneven.
6) When working on a slope, the front wheels should be kept vertical to obtain good adhesion by tilting the front wheels. It is strictly forbidden to use a grader when the transverse slope is greater than 10°.
7) When working on the edge of a newly filled roadbed, the grader should be at least 1m away from the edge of the roadbed to prevent collapse.
8) When performing shoveling, scraping, or shoveling soil with the corner of a knife and using a tiller, it is best to use a low speed gear; when scraping on loose soil, a low speed gear should be used; when scraping on loose soil, a medium speed gear can be used.
