Abstract
The invention discloses a large-caliber glass fiber-reinforced plastic ribbed pipe. The wall of the body comprises a liner layer, a continuous glass fiber-reinforced structure layer and a circumferential outer protective layer, and the outside of the circumferential outer protective layer is provided with a plurality of glass fiber fabric reinforcing rib rings which are arranged at intervals. The comprehensive internal pressure-resisting and external load-resisting capability of the large-caliber glass fiber-reinforced plastic ribbed pipe provided by the invention is greatly enhanced. The inner wall of the large-caliber glass fiber-reinforced plastic ribbed pipe is smooth, the rigidity of the large-caliber glass fiber-reinforced plastic ribbed pipe is high, and the size of the rib ring and the rib density can be designed according to rigidity requirement; compared with the rigidity of the pure glass fiber-reinforced plastic smooth pipe, the rigidity of the large-caliber glass fiber-reinforced plastic ribbed pipe is higher, and the large-caliber glass fiber-reinforced plastic ribbed pipe is lighter and stronger than the glass fiber-reinforced plastic mortar pipe; and as a novel delivery pipe, the large-caliber glass fiber-reinforced plastic ribbed pipe has the advantages of corrosion resistance, low fluid resistance, long service life and the like, is easy to maintain, and is particularly applicable to the fields of deeply buried large-caliber drainage pipelines, seawater delivery, seawater desalination and the like.
Description
Technical field
The present invention relates to heavy-caliber fiber reinforced plastic pipe.
Background technique
At present, fiber reinforced plastic pipe is divided into two kinds of pure fiber reinforced plastic pipe and glass fiber reinforced plastic sand-inclusion pipelines according to the pipe structure difference, and it is better that pure fiber reinforced plastic pipe is born interior pressure, stable performance, but it is low to carry rigidity outward.Glass fiber reinforced plastic sand-inclusion pipeline is to add in process of production the fillers such as silica sand, in order to improve external rigidity, compares with pure fiber reinforced plastic pipe that to have rigidity large, the advantage that cost is low, but also have weight large, flimsy deficiency.
Summary of the invention
The purpose of this invention is to provide a kind of can rigidity large, fiber reinforced plastic pipe structure that again can high-strength light.
Purpose of the present invention is come specific implementation by the following technical programs:
Heavy caliber glass fiber reinforced plastic finned tube, body tube wall comprise successively that from inside to outside backing layer, continuous glass fibre strengthen construction layer, hoop external protection, are provided with the glasscloth reinforcing rib ring that several intervals arrange in the outside of described hoop external protection.
Further, several described glasscloth reinforcing rib rings are evenly distributed on the body tube wall circumference, can design muscle ring size and density according to rigidity requirement, the cross section central authorities of described glasscloth reinforcing rib ring are the trapezoidal of protuberance, and the both sides along continuous straight runs extends.
Described backing layer adopts glasscloth to strengthen compact texture;
Described continuous glass fibre strengthens construction layer and adopts the even reciprocating cross of continuous glass fibre to form netted winding enhancing;
Described glasscloth reinforcing rib ring is prefabricated in advance, twines by hoop to make itself and tube wall form one.
Described backing layer, continuous glass fibre enhancing construction layer, hoop external protection, glasscloth reinforcing rib ring are composited by resin matrix.
Described backing layer: be composited by surperficial felt, needled mat and resin matrix;
Described continuous glass fibre strengthens construction layer: be composited by continuous glass fibre winding yarn and resin matrix;
