In the slope support project of the Cheliwan Park project, the Xieyan 90 concrete wet spraying machine plays a key role. With its advanced technology, it has greatly reduced dust pollution and effectively improved the construction environment. At the same time, the wet spraying machine has high working efficiency and can quickly complete the concrete spraying operation, significantly improving the construction progress. Moreover, it can accurately control the amount of concrete, reduce rebound, and ensure the quality of the project, laying a solid foundation for the smooth progress of the Ningde Cheliwan Park project.
