Leakage and sedimentation countermeasures - Water guide pipe "Miedoren" <NEXCO standard compliant>
Contributing to the longevity of aging tunnels and culverts. Numerous achievements in leak prevention and spalling prevention! Cold-resistant types are also available, achieving measures against icicles.
The "Mie Drain Series" water diversion pipes from Sanju Heavy Industries are products used for preventing water leakage and spalling from joints and cracks in tunnels and culverts, as well as for icicle prevention. They have a wealth of adoption records in repair work for aging tunnels and culverts, primarily in public works. 【Main Lineup】 <EF Series> Main type adaptable for both linear and surface water diversion - Highly robust, serving as both "water leakage prevention work" and "spalling prevention work" (compliant with NEXCO's small piece spalling prevention test standards) - Allows for confirmation of the installation surface condition after installation (transparent type) - Can guide water to the flow end without freezing the leakage (cold-resistant type) <G Series> Integrated structure type specialized for linear water diversion - Offers a certain degree of flexibility while serving as both "water leakage prevention work" and "spalling prevention work" (compliant with NEXCO's small piece spalling prevention test standards) - Can be installed in narrow arch areas of tunnels and single-track tunnels <MJ Series> Adaptable for both linear and surface water diversion, featuring a non-combustible aluminum composite panel type with a non-combustible certification number - In addition to being non-combustible, it possesses excellent weather resistance, corrosion resistance, and pollution resistance *For more details, please download the PDF or feel free to contact us.
basic information
"Why is a 'water conduit' necessary?" The physical lifespan of infrastructure such as bridges, roads, tunnels, water supply and sewage systems, and public facilities is generally said to be around 50 years. During the period of rapid economic growth from the 1960s to the 1970s, public investment advanced, and about half of the current public facilities were built during this time. In other words, there are many infrastructures that have exceeded their 50-year lifespan, and by 2026, the number of aging tunnels will account for 44% of approximately 10,000 in total, worsening the situation. To address these issues, tunnel maintenance projects aimed at countermeasures for the aging of existing tunnels and safety measures for road traffic are being emphasized, and as these projects increase, the need for water conduits arises. *NETIS registration achievements available (up to R3.10)*
