Tunnel construction increased
source：未知 time：2024-06-24 13:40nbsp; click：
With the continuous advancement of global urbanization, the population concentration is increasing, and the demand for transportation between cities is becoming increasingly strong. As an important channel connecting cities, tunnel engineering plays a key role in transportation. In recent years, my country's tunnel and underground engineering construction has also developed rapidly, and the number of tunnel construction has increased rapidly.
The attached vibrator consisting of a high-frequency vibrator and a frequency conversion cabinet is the most commonly used solution in the tunnel industry. The system has the characteristics of large exciting force, wide radiation range, small amplitude, high working efficiency and long life. It can greatly improve the density and surface smoothness of concrete, reduce the possibility of deformation of steel formwork, and extend its service life.
However, since tunnel construction will be affected by the climatic environment, such as plateau, severe cold, freezing, wind erosion, etc., a single high-frequency vibration system cannot perfectly cope with this series of problems. Therefore, in addition to the attached vibration solution, an inserted vibrating rod is also required for auxiliary vibration.

Therefore, in addition to the attached vibration solution, an inserted vibrating rod is also required for auxiliary vibration.
Issues that need to be noted during construction:
1. Check and tighten all vibrator fixing nuts before each pouring.
2. Check the formwork for reinforcement to avoid deviation.
3. Check whether the control system is normal.
4. After the vibrator is started, it is not allowed to start other vibrators midway.
