There are dry spraying and wet spraying for road construction spray concrete. What is the difference between the two?

Shotcrete uses compressed air to transport concrete mixture in a certain proportion through pipelines and spray it onto the sprayed surface at high speed to solidify and harden, thereby forming a concrete supporting layer. In recent years, shotcrete technology has been widely used in construction, railway and highway tunnel construction, mine tunnel construction, slope reinforcement and other fields with its simple process, unique effects, economical cost and fast construction speed.

What stages of development have my country's tunnel construction technology experienced? What are the new results so far?

Our country has a long history of tunnel engineering construction, but before 1949, the tunnels were small in scale and the construction technology was relatively backward. After the founding of the People's Republic of China, with the development of various construction undertakings, a large number of tunnel projects were built, and construction technology has also been greatly improved. At present, the New Austrian method has been widely used in the construction of tunnel engineering mines in my country; in addition to the drilling and blasting method, tunnel boring machine construction has also begun to be used in the construction of tunnels in rocks; the open excavation or cover excavation method is used in the construction of shallow tunnels in cities and other places. Underground continuous walls began to be used, and the shield tunneling method and shallow burial underground excavation method used in underground excavation have reached a high technical level.
