The "OLY Method" is a pavement covering construction method that employs a newly developed steel L-shaped retaining wall (OLY), achieving a reduction in construction time and high safety. By using OLY to install the covering panels in advance, there is no need to repeatedly perform temporary restorations as in conventional methods. All work after installation can be carried out within the covering, and at the end of the work, the covering panels can simply be closed, allowing for maximum utilization of permitted time for construction. This method features clear and simple construction procedures. Furthermore, it enables cost reduction through savings on material costs, disposal fees, and a decrease in transportation vehicles. 【Features】 ■ Simple and clean construction ■ High safety ■ Improved work efficiency and economy ■ Patent obtained for pavement covering method [Patent No. 4767191] ■ Utility model registration for retaining panels used in covering work [Registration No. 3131502] *For more details, please request materials or view the PDF data available for download.

"PCALS" is a revolutionary pipe-in-pipe method that allows for the safe and rapid installation of new piping within existing pipes with elevation changes, using battery-powered locomotives and pipe transport connection trolleys. Our company has developed this technology and obtained a patent for it. It can run continuously through flat sections, overpasses, and curves. By adopting the Abt system, it can operate on slopes of up to 32 degrees. Additionally, the short construction cycle time significantly reduces the overall construction period. 【Features】 ■ No need to change setups during transportation in curved and sloped sections ■ Capable of running on a 32-degree longitudinal slope ■ Quick joining with the piping centering function *For more details, please contact us or download the catalog.
