The mud solidification system primarily utilizes HID-Strong Mixing Solidification Machines and HID-High Pressure Accurate Dosage Solidifier Delivery Units, enabling direct solidification equipment operation on soft mud foundations without being restricted by construction conditions or requiring temporary facilities. By adopting the mud foundation stabilization system, site soil balance can be achieved, preventing the transportation of mud off-site, while also addressing issues related to purchased subgrade materials. This approach optimizes environmental protection and economic efficiency, featuring an accurately (adjustable) dosed powdered solidifier delivery unit. It transports the solidifier in a quantified manner through pipes using high-pressure air to the mixing unit, completing the mud solidification process.
