SR-LG construction method

"Long-distance pumping" backfill filling method using plastic grout.

* NETIS Registration Number: HK-120037-VR * Quality standards compliant with the design and construction guidelines for backfill cavity injection in sheet pile method tunnels at NEXCO * Capable of long-distance pumping (Track 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 materials do 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 properties, work in flowing water is easy, making it an ideal method for sites with groundwater, standing water, or flowing water. * Working environment The installation of plants externally and the liquid nature of the plastic materials result in minimal dust generation in the working environment inside the structure.
