The hottest problems faced by construction machine

Problems faced by construction machinery in the 21st century

Guide: the second tension machine is an experimental machine used for mechanical property experiments such as stretching, tightening, bending, shearing and peeling of materials. In the 11th century, human beings are facing three major crises: population, resources and environment. In order to expand human living space, comprehensively develop and utilize natural resources, and protect the ecological environment, the 21st century puts forward higher and newer requirements for construction machinery.

in the 21st century, mankind is facing three major crises: population, resources and environment. In order to expand human living space, comprehensively develop and utilize natural resources, and protect the ecological environment, the 21st century has put forward higher and newer requirements for construction machinery. Construction machinery will face the following problems:

(I) how to improve the labor productivity of the construction industry

although the mechanization of polyurethane in the construction industry can only be achieved by meeting the 250 w/s requirements of the new national standard B1 level combustion growth rate index (f/gra is constantly consumed and reduced) w/s), it still retains the small production mode of one person and one equipment, relying on

technology and manual operation, which makes the labor productivity impossible to be improved. Therefore, it is urgent to carry out a new technological revolution, transition to the socialized mass production mode, and realize the industrialization of buildings

(II) how to adapt to the new requirements of the construction industry

1, the expansion of the construction field. Develop underground, high-altitude and ocean, and march into the universe. The urban ground is reserved for human habitation and greening to maintain a good ecological environment. The land separated by rivers and seas will be connected by tunnels, which requires a large number of all kinds of underground construction machinery. The greening and utilization of deserts require desert development machinery, marine development machinery for ocean development, etc.

2. The construction scale is huge -- super high, large and heavy buildings. Large scale water conservancy projects, ultra deep underground projects and long-span bridges for equipment manufacturers of recycled plastic granulators

advanced construction engineering -- high-grade and exquisite buildings, high-grade highways, high-speed and low-cost engineering construction

(III) how to change the backward image of construction industry and construction machinery

construction industry is a heavy physical work that people are unwilling to do. Construction machinery has backward features such as poor operating environment, high vibration and noise, and the mortality rate of construction engineering is the highest in all walks of life. At present, advanced countries have put forward new plans for the design of construction machinery,

people-oriented, ergonomics first, if the construction machinery is the driver and the people who see it are satisfied

(IV) how to protect the environment

due to the strengthening of environmental protection awareness, construction methods and engineering machinery that cause great public hazards will be eliminated and replaced by green construction and green machinery
