Abstract

900,530. Drain pipes. HORN, A. March 16, 1961 [March 21, 1960], No. 9716/61. Class 99(2). A pipe for drainage or irrigation is wholly or partly of porous concrete and has an ogival cross-section, the point being at the top of the pipe; the pipe has a substantially flat underface. As shown, the base of the pipe is formed with continuous or interrupted recesses, flutes or grooves 7, 8, and the parting boundary between the upper dense or porous portions and the lower porous or dense portions of the pipe is along upwardly inclined planes 9. For use in soft soils the pipe may have a widened base or be provided with feet 10.
