A drainpipe fixing pile is provided to offer convenience at the construction of a drainpipe laid through an interlayer slab and to fix a drainpipe more stably by attaching sliding grooves tightly to the drainpipe. A drainpipe fixing pile comprises a fixing pile main body(10) formed in a circle and provided with many projections on the inner surface and a cut portion(11) for expansion at one side, many thermal insulation housings(12) installed along the circumference at regular intervals and provided with a space and an insertion hole to insert thermal insulation materials(30), sliding grooves(13) formed between the thermal insulation housings to insert a press piece, and press pieces(20) provided with many projections(22) at the inside and flanges(21a,21b,21c) at the inside and the outside at different heights to be suspended on an outer slab and an inner fixing pile main body, thereby to reduce the inflow of impurities, air or water to the sliding grooves and to prevent the decrease in adiabatic efficiency and the deformation of a product. |
