Erosion Control System for Slope And Tailing Stability. Flexible Drainage Sock Pipe up to 10” in diameter can be installed in a single pass under the water on a precise grade using the DeWind One-Pass Trencher. With the aid of dual automatic laser levels mounted on the Trencher boom, flexible drainage pipe can be installed on the exact grade to facilitate proper gravity drainage of failing slopes, dams, tailings piles and ponds. The One-Pass Trenchers can install miles of deep drainage pipe down steep slopes on perfect grades. The drainage pipe is installed under the water table without the need to install construction-dewatering systems. Unlike excavators that must dig mass excavations to install deep drainage pipe the One-Pass technique installs the pipe without an open excavation and there are minimal spoils produced during the installation process. Due to the minimal disturbance to the soils during the installation process there is little or no site restoration required. Details & Benefits: Installation:Single Pass Automatic Laser Levels No Need for Construction-Dewatering Systems Minimal Site Restoration Needed © 2012 Dewind.

Direct Bury Of Ductile Iron And PVC Pipe: UNBELEIVABLE! One-Pass technology that can install ridged pipe in a single pass…. UNDER THE WATER! DeWind’s uniquely designed trench box created specifically for our One-Pass Trenchers can install rigid pipe like PVC, dual wall corrugated, ductile iron pipe and more in a continuous trenching operation directly under the water table. This ingeniously designed trench box is watertight and allows for pipe installations in soils with high water tables avoiding the cost and hassle of installing construction dewatering. The rigid pipe is handled hand free with a remotely operated robotic crane. The pipe is picked up by the crane and set into the trenchbox where custom mechanisms hydraulically force the pipe into the secure gasketed sealed end of the of the previously installed pipe while pushing the pipe out of the box making room for the section of pipe to be installed. This is a seamless, continual operation performed while the trencher is advancing backwards along the alignment. This Technology is priceless for contaminated sites where dewatering is cost prohibitive. Details & Benifits: Trench Depths:0-12′ deep Trench Width:0″- 24″ wide Benefits:No open excavations, No trench shoring, No dewatering. Saftey:No dangerous open excavations. © 2012 Dewind.
