The present invention relates to a method for constructing an environmental-friendly sewer pipe comprising: manufacturing a synthetic resin protective plate comprising a bottom protective plate corresponding to a bottom slab of the sewer pipe, a protective plate main body having a retaining wall protective plate corresponding to a retaining wall of the sewer pipe, a bottom wire mesh installed inside of the bottom protective plate, a wire mesh consisting of a retaining wall wire mesh installed in the retaining wall protective plate, a bottom protective plate steel bar with the inner end welded to the bottom wire mesh and protruding from the lower part of the bottom protective plate, and a protective plate steel bar consisting of a retaining wall protective plate steel bar with the inner end welded to the retaining wall wire mesh and protruding from the outer side of the retaining wall protective plate; securing the synthetic resin protective plate on a crushed stone layer laid on the bottom of an excavation hole while a bottom slab steel bar is connected; arranging the retaining wall steel bar, as well as performing an installation process of a form and a concrete cast-in-place process while the retaining wall protective plate steel bar of the synthetic resin protective plate is connected. Since installation is made when a bottom slab of a sewer pipe and a synthetic resin protective plate on a retaining wall are firmly coupled, construction is simple and the bottom and inner wall surface of the sewer pipe do no corrode or are corrupted by chemicals contained in the sewage, such as acids, alkalis, salts, and oil and corrosive material in the soil. Since installation is made when the synthetic resin protective plate is firmly attached to the bottom slab of the sewer pipe, even if large and heavy foreign materials flowing in with sewage transferred along the sewer pipe collide with the bottom protective plate and the retaining wall protective plate of the synthetic resin protective plate, long term maintenance is possible without an escape of the synthetic resin protective plate comprising the bottom protective plate and the retaining wall protective plate. |
