Attraction dredging and pumping method: High concentration and thin layer dredging using a mud suction and pressure delivery system.
Suction with negative pressure without disturbing the sediment! Dredging is done horizontally and thinly without stirring up the sediment.
The high-concentration, thin-layer dredging technology using a mud suction and pressure delivery system is a dredging method that employs a negative pressure suction system to draw high-concentration mud in thin layers and transport it via pipeline using compressed air. It dredges without stirring up the bottom sediment, maintaining a horizontal thin layer (with a dredging record of 30 cm thickness). By using a negative pressure suction method, it dredges without disturbing the bottom sediment and suppresses the occurrence and spread of turbidity. Additionally, due to the pipeline pressure delivery method, it reduces environmental impact on the surroundings (such as odors and interference with general traffic). It minimizes the intake of excess water, allowing for processing plans in narrow distribution areas and enabling sun drying. 【Features】 - Dredges horizontally in thin layers without stirring up the bottom sediment - Dredges without disturbing the bottom sediment using a negative pressure suction method - Suppresses the occurrence and spread of turbidity - Minimizes the intake of excess water during mud suction for high-concentration dredging - Dredged sediment is transported through the pipeline using compressed air For more details, please contact us or download the catalog.

Since its founding, Koyanagi Construction Co., Ltd. has prioritized contributing to the local community and our customers under the motto "Serving the prosperity of the region." We have actively engaged in social contribution activities through construction. In recent years, abnormal weather and environmental pollution have become serious social issues, but Koyanagi Construction has quickly established "Harmony between life and nature" as our corporate theme. We are developing new methods in projects such as inland waterway dredging and slope greening, and we are committed to protecting and improving the natural environment. We also believe that the true asset of the community is its people, which is why we operate swimming schools, karate classes, and English conversation courses. We are also challenging ourselves to manage educational facilities that can provide the community with health for both the "mind" and "body." For Koyanagi Construction, local talent is an asset as well, and we are committed to thorough employee training to nurture as many "people who can contribute to the community" as possible, growing together with the company. Moving forward, we will continue to strive to be a company that can be of service to everyone while coexisting with nature and walking alongside the community.
