A sediment removal system that promotes settlement by the jet flow of a submersible pump to remove soil from the lower part of the blade edge.
The "KG Caisson Cutter Sediment Removal Device" is a technology that removes sediment from the bottom of the cutter during the installation of open caissons using the jet flow from an underwater pump. With approximately ten times the water volume and significant jet force compared to conventional water jets, this device can also handle the installation in hard sandy soil layers. By attaching a 90° elbow to the underwater pump, downward jet discharge is achieved. Please feel free to contact us if you have any inquiries. 【Expected Effects】 ■ Improved removal efficiency with strong jet force, ensuring reliable removal of sediment beneath the cutter. ■ Remote operation of the device eliminates the need for divers to perform high-pressure work, reducing labor costs. ■ Downward jet projection breaks up sediment in the central part of the caisson, enhancing excavation efficiency. ■ After installation is complete, reliable removal of sediment adhering to the cutter improves integration with the bottom slab concrete, reducing leakage. *For more details, please download the PDF or feel free to contact us.

basic information
【Work Procedure】 1. Lower the main unit to the blade opening position while placing the guide roller against the side wall. 2. Operate the pump to discharge the jet stream and move the main unit up and down several times to remove the soil at the blade opening. 3. After temporarily stopping the pump, operate the mixer and move the pump cart forward. 4. Restart the pump to remove the soil at the back of the blade opening. 5. Move the position of the main unit and repeat the same actions sequentially. *For more details, please download the PDF or feel free to contact us.
