Abstract

The invention provides a composite reinforced discharge hose, comprising a hose wall bearing body, an inside liner, a filtration layer and a protection layer, wherein the hose wall bearing body consists of a cylindric spiral spring and two reinforced rib rods arranged on outer rings thereof; the inside liner is polyester filament; the protection layer is a knitted polyester mesh sleeving; the composite reinforced discharge hose has enough radial and axial compressive strength and good water permeability, and can effectively prevent sharp objects such as cobbles and the like from piercing the filtration layer. The composite reinforced discharge hose has the advantages of simple structure, easy industrialized production, low cost, convenient construction installation, high efficiency and lowlabor intensity, and can play roles of discharging water and reinforcing subgrade.

Description

Technical field: [0001] The invention relates to a building component for underground drainage, in particular to a hose for underground drainage in roadbed engineering of expressways and railways. Background technique: [0002] At present, underground drainage hoses are used in the subgrade engineering of highways and railways. In the Chinese invention patent 01262555.8, "a permeable pipe with vertical and horizontal reinforcement" is disclosed, which consists of a pipe wall support, an inner lining, and a filter layer. and protective layer. The pipe wall support body is a combination of a cylindrical helical spring and a reinforcing rib placed outside the spring coil. Two or three reinforcing ribs are equally arranged on the inner side of the cylindrical helical spring coil, and are fixedly connected with the inner ring of the spring. There is a layer of plastic protective layer on the surface of the pipe wall support; polyester fiber filaments are wound equidistantly on t...
