Abstract
The invention discloses an underground pipeline, and particularly relates to a glass fiber-reinforced plastic underground buried pipe with a fault location function. The glass fiber-reinforced plasticunderground buried pipe comprises a rebar layer, a glass fiber-reinforced plastic layer, a conveying pipeline, pressure sensors and communication optical cables, wherein the rebar layer is arranged on the outermost side; the conveying pipeline is arranged on the innermost side; the glass fiber-reinforced plastic layer is positioned between the rebar layer and the conveying pipeline; the pressuresensors are arranged on the inner side of the conveying pipeline; the pressure sensors are connected with the communication optical cables; and the communication optical cables are arranged in the glass fiber-reinforced plastic layer. The rebar layer of the pipeline is used for resisting pressure, the glass fiber-reinforced plastic layer resists corrosion, the conveying pipeline is fully-filled during conveying, when the pipeline is broken, pressure intensity of liquids or gases at broken parts is decreased, the pressure sensors in the positions sense the change of pressure intensity, information is transmitted through the communication optical cables, workers conveniently detect faults of the pipeline, and the problems that resources are wasted and accidents are caused due to the fact that pipeline breaking is found not timely in long-distance conveying pipelines are solved.
Description
technical field [0001] The invention relates to an underground pipeline, in particular to a fiberglass underground buried pipeline with a fault location function. Background technique [0002] Underground pipelines are pipelines laid underground for transporting liquids, gases or loose solids. In ancient China, underground drainage pipes made of clay have long been used. When the Ming Dynasty established its capital in Beijing, a large number of bricks and stones were used to build underground drainage pipes. It is about 1 meter wide and about 2 meters high. There are many kinds of modern underground pipelines, including circular, oval, semi-elliptical, multi-circular, oval, rectangular (single-hole, double-hole and multi-hole), horseshoe-shaped and other cross-sectional forms, using steel, cast iron, concrete, Reinforced concrete, prestressed concrete, brick, stone, asbestos cement, clay, plastic, glass fiber reinforced plastic (reinforced plastic) and other materials. ...
