With minimal equipment and easy operation, water replacement is possible! It has also been adopted for earthquake recovery construction, making a significant contribution to restoration and reconstruction.
This technology is an air-pressure-operated sewage pump method that responds to various needs in the sewer restoration work following the Great East Japan Earthquake. Since it does not use a power motor, temporary power sources or generators are unnecessary. Additionally, as it is a completely self-sufficient pump that does not require "priming," high-pressure cleaning vehicles and water supply vehicles are also not needed. Furthermore, it ensures pedestrian safety and minimizes the use of piping materials and safety facilities, making it economical. 【Features】 - Achieves high efficiency and low cost - Provides a hygienic working environment - Allows for water replacement only at the construction site - Quick installation and removal - Enables emergency pipeline openings *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 ■ A special shut-off valve (through-type shut-off valve) is inserted into the existing sewer pipe that is in use, and compressed air is filled to stop the inflow of water from upstream using the shut-off valve function. ■ The wastewater (rainwater) that accumulates in the blocked pipeline is pumped out using a diaphragm pump for the air heart method, via a suction hose connected to the air heart plug. ■ Water can be pumped to downstream manholes or designated locations by connecting temporary drainage pipes (such as suction hoses) according to the site conditions. *For more details, please refer to the PDF document or feel free to contact us.

Applications/Examples of results
Main applications where temporary drainage using the simplified water replacement method (this method) is deemed necessary: - Replacement of aging existing sewer pipes during sewer utilization (open-cut and non-open-cut) - Cases where temporary drainage is required during sewer pipe rehabilitation work - Construction of new manholes or removal of existing manholes (installation and removal of manhole pumps) - Cases where temporary drainage is required during sewer TV camera inspections, etc. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Kyosen Civil Technology Co., Ltd. is a manufacturer and seller of the pipe rehabilitation system "K-2 Method." The "K-2 Method" involves impregnating a K2 liner, which has a tubular resin absorption material covered with a plastic film on both the inner and outer surfaces, with thermosetting resin. This liner is then pulled and inserted into the pipeline, where liquid pressure is applied to the lining material, adhering it to the pipeline wall. The lining material is heated using hot water or a hot water shower, curing the thermosetting resin and forming a CIPP (Cured-In-Place Pipe) within the pipeline. After curing, the plastic film on the inner surface is peeled away, completing the pipe rehabilitation process.
