The rock pipe jacking machine plays an important role in tunnel excavation, and its correct use is the premise to ensure the smooth progress of tunnel construction. Before use, read the instruction manual carefully to understand its use method and safe operation procedures. During use, the following points should be noted:

　　The muck is flying, and the pipe jacking machine is easy to suck in too much fog, dust and mud. Cleaning the machine helps keep it in good working order and prolongs its life.

　　Ensure that the site is stable: when using telescopic brackets, ensure that the ground is level. The plane placement of large rock pipe jacking machines is conducive to maintaining a horizontal position and stability.

　　Check the hydraulic oil regularly: a large amount of hydraulic oil is needed in the operation of the pipe jacking machine, and the hydraulic oil should be checked and changed regularly. When the hydraulic oil fails, it should be dealt with immediately.

　　The maintenance of the rock pipe jacking machine is an important part of extending its service life. The following are some points for attention in the maintenance of the rock pipe jacking machine:

　　The specified maintenance cycle must not be delayed, and the corresponding maintenance work should be carried out according to the maintenance manual.

　　Correctly maintain the lubrication system: Insufficient lubricating oil can easily cause the machine to malfunction. During the operation of the pipe jacking machine, the oil temperature should be kept stable, and the leakage of the lubrication system should be paid attention to.

　　Electrical cables are the key to connecting devices, and they should be guaranteed to be used normally and not damaged for a long time.

　　By understanding the correct use and maintenance of the rock pipe jacking machine and maintaining its good condition, the service life of the machine can be effectively extended and the quality of tunnel construction can be guaranteed.

　　The correct use and maintenance of the rock pipe jacking machine is very important to ensure the quality of tunnel excavation work, and its normal operation and regular maintenance during use should be guaranteed.

　　With the continuous acceleration of urbanization and the continuous advancement of infrastructure construction such as water conservancy projects and transportation projects, rock formations such as quartz sandstone that are difficult to drill have become difficulties that need to be overcome during construction. As an efficient and reliable construction machine for drilling through rock formations, the rock pipe jacking machine has been widely used and promoted.

　　The development of rock pipe jacking machines can be traced back to the 1950s, when pipe jacking technology was mainly used in eroded rock and mudstone formations. Since the late 1980s, with the gradual increase in domestic and foreign markets for rock layer pipe jacking technology, rock pipe jacking machines have been more extensively researched and developed. At present, the technology of rock pipe jacking machines at home and abroad is relatively mature, and the market scale is relatively large.

　　The rock pipe jacking machine is mainly composed of an engine, a hydraulic system, a control system, a driving head, a steering head and a drill pipe. Its main working principle is to use the drill bit to cut the rock, break the rock formation and push it into the drill hole, and then use the drive head to drive the drill pipe and the propulsion tube to the next drilling position.

　　In rock formations that are difficult to drill, such as quartz sandstone, rock pipe jacking machines need to use more intelligent technology to overcome difficulties. Some enterprises have developed rock pipe jacking machines with cemented carbide drill bits, which combine ultrasonic vibration technology and drill pipe adaptive control, and can perform efficient and stable pipe jacking in quartz sandstone and other rock layers with high hardness, high strength and high toughness. drilling. In addition, testing the physical and mechanical properties and data analysis of different rock layers is also a key step in optimizing the rock pipe jacking machine.

　　Generally speaking, the development of rock pipe jacking machines is a process of continuous optimization and technological innovation. Only by continuous exploration and practice can more efficient and intelligent rock formation construction technology be realized.
