With the continuous development of tunnel construction technology, the requirements for tunnel project quality, operational safety and occupational health are also constantly increasing. Against this background, mechanized equipment is gradually used in various processes of tunnel construction to replace traditional manual labor. Among them, the concrete wet spray trolley has become the mainstream equipment for shotcrete support operations.
The concrete wet spray trolley has demonstrated its unique advantages in the initial support operations of long tunnels, which has greatly promoted the application of mechanized construction in tunnel projects. Compared with traditional artificial sprayed concrete, wet spraying trolleys have the following significant advantages:
1. Improve construction efficiency: The concrete wet spray trolley can operate continuously, which greatly shortens the construction time and improves the construction efficiency. Compared with manual spraying, mechanized equipment can more accurately control the spray volume and coverage, thereby reducing material waste.
2. Ensure project quality: The wet spray trolley can spray concrete evenly and stably, ensuring the uniformity and stability of the supporting structure and significantly improving the project quality. Mechanized construction reduces the impact of human factors on project quality and ensures high standards of support operations.
3. Improve work safety: During tunnel construction, safety issues have always been a top priority. The use of concrete wet spray trolleys can reduce workers' working time in harsh environments and reduce safety risks. At the same time, the use of mechanized equipment can avoid human operating errors and further ensure construction safety.
4. Improve occupational health: Traditional manual spraying concrete operations often produce a large amount of dust and noise, which adversely affects the health of workers. The concrete wet spray trolley adopts closed operation, which effectively reduces dust and noise pollution, improves the working environment of workers, and enhances occupational health.
The application of concrete wet spray trolleys in tunnel construction not only improves construction efficiency and project quality, but also significantly improves operational safety and occupational health. With the advancement of science and technology and the continuous development of construction technology, the concrete wet spray trolley, as an ideal choice for tunnel engineering support, will play an increasingly important role in future tunnel construction, pushing tunnel construction into a more mechanized , a new era of intelligence.
