Proposal for "EP Sleeve" for High-Rise Buildings with Vibration Isolation and Earthquake Resistance

The lightweight polyethylene personnel passage EP sleeve supports beam penetration and labor-saving in the construction of high-rise buildings (earthquake-resistant)!

"Streamline with stable high-pressure polyethylene manholes (manholes)!" - To designers of high-rise and earthquake-resistant buildings - [In response to everyone's requests amid the recent increase in beam width, we are now able to produce the polyethylene manhole EP sleeve with a basic manufacturing length of 1900mm, specifically for EP-600 (inner diameter: 600 / outer diameter: 700mm), with lengths exceeding "L=1900mm" now possible.] <Effects of introducing polyethylene manholes (manholes) EP sleeve> ● High pressure resistance: Thanks to its double-walled corrugated structure, it maintains strength against impacts and external pressure during concrete pouring. ● Lightweight material: Extremely lightweight compared to heavy materials. It is easy to transport and handle on-site, leading to labor-saving and increased efficiency. It weighs about 17kg/m compared to approximately 53kg/m for rigid PVC pipes! ● Reduced environmental impact: There is no concern about water contamination (such as red water) due to rust or corrosion, making it an environmentally friendly manhole. ● Chemical resistance: It has high resistance to acids and alkalis, making it a material that is less likely to deteriorate even in buried environments. *For more details, please feel free to request a catalog directly via email or download it from the "EPJ Corporation" special site on Ipros through the related links.
