"Long-distance pumping" backfill cavity filling method using plastic grout.
* NETIS Registration Number: HK-120037-VR * Quality standards that comply with the design and construction guidelines for backfill cavity injection in sheet pile method tunnels at NEXCO * Capable of long-distance pumping (Record: 4,000m) The plastic grout material is non-air-based, allowing for long-distance pumping. * Construction possible at external plants Main materials and plasticizing materials (liquid) can be pumped from external plants, and the main material does not harden alone for long periods, resulting in fewer troubles during pumping. * Environmentally friendly using recycled materials Utilizing fly ash contributes to effective resource utilization. * Ensuring high quality With high underwater non-separation, work in flowing water is easy, making it an optimal method for sites with groundwater, standing water, or flowing water. * Working environment The installation of plants externally and the liquid nature of the plastic material result in minimal dust generation in the working environment inside the structure.
