Abstract

A drainage support/diverter system for use in connection with a perforated pipe drainage system within a drainage trench, comprising a number of drainage support/diverters that create impermeable barriers to moisture flow along the length of the trench outside the perforated pipe, such drainage support/diverters are positioned upon intervals along the drainage trench with their lower ends placed to a depth at least as deep as lowest depth of the drainage trench where each drainage support/diverter is placed, extend laterally at least as wide as the widest point of the drainage trench where each drainage support/diverter is placed and are formed at their upper ends with a recess corresponding to a portion of the diameter of the perforated pipe such that moisture outside the perforated pipe is forced to enter the perforated pipe at the point of each drainage support/diverter.

Claims

1. A drainage support/diverter system for use within a drainage trench containing perforated pipe comprising, a number of drainage support/diverters, of solid and substantially flat structure, that are positioned upon intervals along said drainage trench, each said drainage support/diverter extending laterally at least as wide as said trench, placed to a depth at least as deep as the bottom surface of said trench and being formed with a recess extending below the uppermost surface of said drainage support/diverter and corresponding to at least a portion of the diameter of said perforated pipe, wherein moisture flowing outside said perforated pipe is directed into said perforated pipe before rising to the level of the uppermost surface of said drainage support/diverter.

2. A drainage support/diverter system for use within a drainage trench containing perforated pipe comprising, a number of drainage support/diverters that are positioned upon intervals along said drainage trench, said drainage support/diverters having extension panels that are laterally extendable to accommodate various trench widths, said drainage support/diverters extending laterally at least as wide as said trench, placed to a depth at least as deep as the bottom surface of said trench and being formed with a recess corresponding to at least a portion of the diameter of said perforated pipe, wherein moisture flowing outside said perforated pipe is directed into said perforated pipe.
