Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
178 words
A method of irrigation comprising the steps of forming at least one outlet aperture in a wall of a water distribution pipe, forming at least one strainer box from a unitary moulding having a plurality of foldable walls at least some of which comprise strands intersecting at cross-over points to form an open mesh, but the strands of each of two pairs of strands being spaced apart to define a pair of open-ended slots, the two slots extending into opposite walls of the box and being of such size and shape as to locate the box over the pipe, folding the walls of the box so as to thereby effect the location of the box over the pipe, placing particulate material into the box and folding a top wall of the box over the opposite walls and thereby retaining the box to the pipe with the particulate material surrounding a portion of the pipe containing the outlet aperture, and distributing irrigation water through the pipe and the aperture therein into the box to percolate through the particulate material.
Claim 2
Independent Claim
178 words
A method of irrigation comprising the steps of forming at least one outlet aperture in a wall of a water distribution pipe, forming at least one strainer box from a unitary moulding having a plurality of foldable walls at least some of which comprise strands intersecting at cross-over points to form an open mesh, but the strands of each of two pairs of strands being spaced apart to define a pair of open-ended slots, the two slots extending into opposite walls of the box and being of such size and shape as to locate the box over the pipe, folding the walls of the box so as to thereby effect the location of the box over the pipe, placing particulate material into the box and folding a top wall of the box over the opposite walls and thereby retaining the box to the pipe with the particulate material surrounding a portion of the pipe containing the outlet aperture, and distributing irrigation water through the pipe and the aperture therein into the box to percolate through the particulate material.
Claim 3
Dependent Claim
34 words
A method according to claim 1 comprising the step of forming a plurality of apertures spaced from one another along the pipe, each aperture having a respective folded strainer box with particulate material therein.
Claim 4
Independent Claim
23 words
A method according to claims 1 or 2 comprising the step of at least partly burying the water distribution pipe in the ground.
Claim 5
