Abstract

The invention aims to provide a steel strip reinforced polyethylene helically-corrugated drain pipe foundation structure and a construction method thereof. According to the technical scheme, the foundation structure is composed of a groove, a water-proof geomembrane, laying layers, poured water, a vibrating needle and a drain pipe, wherein two drain ditches are formed in the bottom of the groove; the laying layers include the foundation laying layer and the stable laying layer; and the drain pipe is composed of filling strips, an outer adhesive layer, outer steel strips, an inner adhesive layer, inner steel strips and hot melting strips. Steel strip reinforced polyethylene helically-corrugated pipes are combined and welded in a hot extrusion mode through the hot melting strips at pipeline connecting ends, so that joints of the two pipes are tightly bonded, jointing seams of pipe openings have certain strength, and then the sealing performance of pipeline connection is reinforced; and during pipeline laying, water pouring and vibration are performed on a sand foundation layer in the groove for pipeline laying, gaps in the sand foundation layer are reduced, and then the sand foundation layer is more compact, so that the number of construction workers, machines and tools is reduced, the operation cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the field of pavement pipeline laying, in particular to a steel belt reinforced polyethylene spiral corrugated drainage pipe foundation structure and a construction method thereof. Background technique [0002] In recent years, with the promulgation of policies to restrict and eliminate concrete pipes by local governments and the improvement of overall environmental protection awareness in urban and rural areas, plastic buried drainage pipes with larger diameters have been used in some areas. However, the rigidity of the large-diameter plastic pipe ring is obviously insufficient, and the application of the steel belt reinforced polyethylene corrugated pipe can make up for the insufficient rigidity of the large-diameter plastic pipe ring. And the sealing of the nozzle is greatly improved by welding technology. In the construction of general steel belt reinforced polyethylene corrugated pipes, because the foundation is not compa...
