The safety requirements for the electrical system when selecting the type of stable soil mixing station include: The emergency soil power switch shall be provided on the console of the stable soil mixing station. In case of emergency, the total power supply shall be cut off, and the emergency power off switch cannot be automatically reset. The cover and the power supply for opening and closing the host of the forced stable soil mixing station shall be provided with an interlock device. When the inspection cover is opened, the power supply shall be cut off, and the main engine cannot be started. In the basic design of the stable soil mixing station, a special grounding grid should be considered, and there should be a reliable electrical connection with the building body and the powder silo. The grounding resistance should be no more than 10Ω. The computer control system should be equipped with an independent grounding grid, and the grounding resistance is not Greater than 4Ω.
The design of the foundation of the Stabilized Soil Mixing Plant should be designed and validated by the architects who have the qualifications for construction according to the actual conditions of the local geology or field of realization. Ground allowable compressive stress is generally 0.2 ~ 0.3MPa, base strength calculated according to GB5007 standards. For harder soils, after the excavation, only the underlying bedding treatment is generally required to pour the basic concrete. After the excavation of the soft foundation, it must be based on the degree of filling after excavation, and choose different techniques to carry out the basic bottom reinforcement. The commonly used reinforcement methods include hitting plum blossom piles, or increasing the base area to increase the basic bearing capacity, and preventing future foundation cracking and sinking to bring hidden troubles to equipment and production.
