Problems solved by technology

[0002] Cellar wells are commonly referred to as cellars. Most of the cellar wells are low-lying, and the internal temperature cannot be too high or too humid. At present, most cellar well covers are relatively weak, have a short service life, weak compressive strength, and poor waterproof performance. Can not absorb ultraviolet rays, therefore, urgently need a kind of improved technology to solve this problem that exists in the prior art

Abstract

The invention discloses a glass fiber reinforced plastic drainage pit cover and a manufacturing method thereof. The glass fiber reinforced plastic drainage pit cover comprises a drainage pit cover body, a convex edge, a reinforcing rib net, a plurality of transverse reinforcing ribs and a plurality of longitudinal reinforcing ribs, wherein the convex edge is arranged at the outer side of the drainage pit cover body; the reinforcing rib net is fixedly arranged at the inner side of the drainage pit cover body; and the plurality of transverse reinforcing ribs and the plurality of longitudinal reinforcing ribs are fixedly arranged on the surface of the inner side of the reinforcing rib net and are vertical and intersectant. The glass fiber reinforced plastic drainage pit cover is simple in preparation technology and anticorrosive, has high strength and prolonged service life, can absorb lots of ultraviolet rays and can be used under lots of harsh conditions; and the waterproof heat isolation effect of the glass fiber reinforced plastic drainage pit cover is greatly improved than that of a traditional drainage pit cover.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a glass fiber reinforced plastic cellar manhole cover and a manufacturing method thereof. Background technique [0002] Cellar wells are commonly referred to as cellars. Most of the cellar wells are low-lying, and the internal temperature cannot be too high or too humid. At present, most cellar well covers are relatively weak, have a short service life, weak compressive strength, and poor waterproof performance. Can not absorb ultraviolet rays, therefore, urgently need a kind of improved technology to solve this problem that exists in the prior art. Contents of the invention [0003] The purpose of the present invention is to provide a fiberglass cellar well cover, which has high strength, deformation resistance, corrosion resistance, can absorb a large amount of ultraviolet rays, has a greatly improved waterproof and heat insulation effect compared with...
