  • Method and apparatus for field fabrication of socked perforated drains
    Patent number: 10968588
    Abstract: A mobile fabrication solution for onsite assemblage of earth drains for ground stabilization that includes a despooling carousel for uncoiling corrugated tubing from a stock supply, and for feeding the stock tubing into an extrusion head unit. The head unit contains counter-rotating wheels that grip and drive the tubing out through a collet into a filter sock and into a collection trough. One end of a stock supply of fabric filter sock is attached to the collet exteriorly of the head unit to the collet and is unrolled along the trough. When the corrugated tubing is ejected it fills the sock within the trough and may be cut to the desired length onsite, eliminating waste.
