CN2227247Y - Fibre winding and sand adding pipeline - Google Patents

Abstract

The utility model relates to a fibre winding and sand adding pipeline for conveying materials, mainly comprising an inner lining layer (1), an inner winding layer (2) which is covered on the outer surface of the inner lining layer (1), an outer winding layer (3), an outer proctection layer (5) which is wound on the outer surface of the outer winding layer (3), and a sand adding layer (4) which is covered between the inner winding layer (2) and the outer winding layer (3). The utility model solves the defects of the existing product has lower rigidity and is not suitable for underground embedding, has the advantages of high strength, high rigidity, corrosion resistance, low cost, etc., and is suitable for using as a water delivering pipeline and other waste draining pipelines.

Description

A kind of fiber twines sand-adding pipe

The utility model belongs to the coiling pipe, is meant that especially a kind of fiber of conveying material twines sand-adding pipe.

Common in the market reciprocating type fiber twines on the FRP tubular construction and is divided into inside liner, construction layer (being divided into inside and outside winding layer) and external protection; all make for these three layers with glass fibre and resin; the shortcoming of this product is lower in pipeline rigidity; be unsuitable for underground burying underground; if improve pipeline rigidity, then former product cost is higher.

The purpose of this utility model is to provide a kind of the improved fiber winding of existing product sand-adding pipe is reached the purpose that overcomes the prior art deficiency.

Structure of the present utility model is:

A kind of fiber twines sand-adding pipe, comprises inside liner (1), is compound in interior winding layer (2), the outer wrap (3) of inside liner (1) outer surface and the external protection (5) that is wound in outer wrap (3) outer surface; It is characterized in that being compounded with between interior winding layer (2) and the outer wrap (3) and add layer of sand (4).

Accompanying drawing of the present utility model has:

Adding layer of sand (4) is that main material is made with silica sand and resin.

Fig. 1 is a cross-sectional configuration schematic representation of the present utility model.

Accompanying drawing has provided embodiment of the present utility model, in conjunction with the accompanying drawings embodiment of the present utility model is described as follows:

The overall structure of present embodiment as shown in Figure 1; wherein inside liner (1) is that main material is made with 70% resin and 30% glass fibre; external protection (5) is that main material is made with the resin; it is that main material is made that inside and outside winding layer (2), (3) are selected 70% glass fibre and 30% resin for use; adding layer of sand (4) is that main material is made with silica sand and resin; inside liner (1), inside and outside winding layer (2), (3) add between layer of sand (4) and each layer of external protection (5) and are bonding compound connection.

The obtained technological progress of the utility model is: by establishing between inside and outside winding layer Put and add layer of sand, make product rigidity big, and corrosion-resistant, the rough inner surface rate is low and cost is lower, Be suitable for as aqueduct and other blow-off lines.

Claims (2)

1, a kind of fiber twines sand-adding pipe, comprises inside liner (1), is compound in interior winding layer (2), the outer wrap (3) of inside liner (1) outer surface and the external protection (5) that is wound in outer wrap (3) outer surface; It is characterized in that being compounded with between interior winding layer (2) and the outer wrap (3) and add layer of sand (4).

2, sand-adding pipe according to claim 1, it is characterized in that adding layer of sand (4) is that main material is made with silica sand and resin.
