Vibration roller rolling subgrade has a certain standard and regulations, which is what, we are divided into four to illustrate:Road Repair Machines

Before rolling, the thickness, flatness and water content of the loose layer should be checked to meet the requirements before rolling. Compaction should be based on the field compaction test to provide the thickness of loose piles and control compaction times. If the control of the compaction of more than 10 times, should consider…

The small hand-held roller was first introduced in the United Kingdom in the 1980s, and a company called Pieve's machinery factory developed and produced the first small-scale roadbed. At that time the production of the roller is a very simple structure, the operation is not convenient. In the 1990s, China introduced the production technology of the Peeffer road roller, and developed a hand-held double-wheel roller and cab roller.Road Repair Machines

Earth driveway preparation starts by taking levels across and along the road. If a road grading machine is not available, this is done by hand. The road is first leveled and the hump at the center removed and flattened. After the road is leveled, wetting and compaction is done to achieve a firm base. The rolling is done three times wet and four times on dry surface. After the base is firm, hardcore is laid by hand packing it before it is compacted.Road Repair Machines

Mechanical equipment operation management

Mechanical equipment operation management, mechanical equipment management is the primary task. Mechanical equipment users must first strictly in accordance with the equipment operating procedures and instructions to operate the use of equipment, conscientiously implement the construction process, in accordance with the technical requirements of construction operations, obey the command of the construction site personnel to ensure the quality of…

Scientific management theory is proposed by Taylor, belongs to the classical management theory category. Although the scientific management theory has been more than 100 years of history, but still play a huge role in scientific management is mainly focused on production operations management, the purpose is to improve the efficiency, which is very suitable for use in road machinery and equipment management. However, Taylor's theory of scientific management of the limitations of one is that…

Clearly maintain the responsibility of personnel. Cultivate a skilled, skilled maintenance team, and road construction enterprise scale, mode of operation, mechanization and equipment capacity consistent with a reasonable proportion. Equipment on-site management is an important part of the management process, the equipment maintenance management personnel inspection mechanisms and mechanisms of responsibility together, a clear quality and safety equipment, equipment maintenance personnel…

At present in the world, the concrete as the most widely used, the largest amount of a building material, study the characteristics and properties of concrete can be more convenient application of concrete, give full play to the advantages of concrete. To make concrete better serve the coordinated development of human services and the environment, and further promote the concrete scientific and technological progress, in order to continue to explore the development approach and technological…
