Construction Scheme for Solidification Mixing Head
Pre-construction:
At least 4 key personnel are required: an electrician, a backend technician, an excavator operator, and at least one general laborer (assist in connecting and installing pipelines).
Prerequisite:
First, open an account with the local State Grid and complete the formalities. Relevant personnel will communicate the wiring route and the power capacity of the entire equipment.
Regarding Equipment selection
- Storage tank – depending on tonnage
- Mixing tank – divided into vertical and horizontal types
- Grouting pump
- Slurry pipeline
- Excavator with a curing head
Regarding powergeneration
① Power generation: Generate electricity using a generator with a minimum capacity of 100kW. Depending on different working conditions, determine whether to use a primary switchgear alone or a primary switchgear plus a secondary switchgear, which are then connected to the backend switchgear and the grouting pump switchgear.
② On-site power supply: Take power from the high-voltage lines at the construction site, then connect to the primary and secondary switchgears, followed by the backend switchgear and the grouting pump switchgear. (Note: At least primary and secondary switchgears are required.)
Regarding water intake
① On-site water extraction: Connect the pipeline of the backend water storage tank to a nearby river or ditch for water pumping, with a minimum capacity of 40 cubic meters per hour. (Since the water extraction range is uncertain, the pipeline is not included in the equipment. Please contact us if needed.)
② On-site well drilling: Depending on the area – the drilling methods and equipment used differ for soft soil and rocky ground.
(The cost in China is at least 3,000 RMB; the specific price depends on the local drilling depth and equipment rental fees.)
Regarding pipeline cleaning procedures
Prerequisite: In high-temperature conditions, if work is suspended for 30 minutes to 2 hours, or if the shift change interval is too long, pipeline cleaning is mandatory. Each cleaning must take at least half an hour and requires two personnel (the backend operator and the excavator operator).
① The backend manager empties the mixing tank.
② The backend manager switches the equipment to manual operation (when switched to manual, the auger will automatically turn off).
③ The backend manager controls the switch from the operating room, injects water into the upper auger, and drains water from the lower auger until a certain amount (1500 liters) is reached.
④ The backend manager presses the discharge button, and the water will automatically flow to the lower auger and then be sprayed out through the slurry pump.
⑤ The excavator operator controls the mixing head to keep it rotating, cleaning the cement residues inside the pipeline and on the mixing head (to prevent cement from solidifying on the mixing head, which may damage it and delay the construction period).

1.Basic Principles and Structure of Solidification Mixing Head
The solidification mixing head is specialized engineering equipment for soft ground treatment, utilizing hydraulic power to achieve forced mixing of soil and solidifying agents. Its core components include mixing blades made of high-strength alloy steel, solidifying agent delivery pipelines, and hydraulic transmission systems. The triangular cutter head or spiral blade design ensures mixing uniformity. Equipped with an intelligent control system, it can monitor parameters like rotation speed and torque in real time, making it suitable for reinforcing various weak foundations including silt and backfill soil.
2.Key Technical Points for Amphibious Construction
When operating in conjunction with amphibious excavators, special attention must be paid to equipment stability and mixing process control. Prior to construction, precise measurements of water depth and silt characteristics should be taken to adjust the solidifying agent ratio (typically 10%-20% cement content). During operation, maintain a mixing speed of 20-50 rpm using a “drilling-mixing-lifting” cyclic process, with particular attention to reducing lifting speed during underwater operations to prevent solidifying agent loss. For high-water-content silt, adding flocculants or increasing solidifying agent dosage is necessary to ensure treatment effectiveness.
3.Construction Safety and Quality Control Measures
Strict adherence to safety protocols is mandatory during construction, with operators wearing life-saving equipment and regularly inspecting hydraulic system seals. For quality control, portable penetrometers are used for on-site strength testing, with particular focus on mixing uniformity to avoid unmixed interlayers. Post-construction, residual solidifying agents must be promptly cleaned and riverbeds properly leveled. Typical engineering cases demonstrate that this technology can improve construction efficiency by over 30% while reducing costs by approximately 40%, showing significant advantages in applications like waterway remediation and bridge foundation reinforcement.
