Abstract
633,589. Draining soil. KJELLMAN, W. Dec. 9, 1947, No. 32510. Convention date, Jan. 8, 1945. [Class 33] A drain for reducing the percentage of water in clay or other grounds having a very low perviousness to water consists of a substantially band - shaped body of a material pervious to water, such as unsized pasteboard having internal longitudinally extending passages. The drain may consist of a number of layers fastened to each other, the surfaces of said layers facing each other having different geometric shapes so as to provide longitudinal passages therebetween, e.g., the layers 1, 2, having passages 3, bearing on each other at the projections 4, joined at the two edges of the layers as in Fig. 1. There may be three interconnected layers, the middle one consisting of substantially parallel strips spaced from each other as shown by the layers 5, 6 and 7 in Fig. 2. Specification 632,902 is referred to.
