Abstract：The seep irrigation underground is a kind of water-saving irrigation technique. At present pipes used abroad are most made of plastic or rubber. So the cost is too high to make it popularized in China market. The pipe-maker we devised uses cement mortar as the main material. This machine was pulled by a tractor and can finish all working procedures such as moving, digging, delivering material, extruding, molding, smoothing, backfilling and so on each time underground. The field bearing capacity and hydraulic pressure in pipe test shows that the quality meets the requirements of design and safety. Field evaluation shows that the field under this seep irrigation method can save 60% water more than the one under flooding method. The cost is low and it is easy to construct, so it is really a new water-saving irrigation technique.
