Embodiment 1

[0071] right Figure 1 to Figure 5 The structure of the reinforced composite pipe 21 shown in this embodiment 1 is illustrated. In the above-mentioned strip-shaped resin mortar body 26, the outer end edges 26a, 26a of the parts located at the side edges of the above-mentioned resin mortar layer 22 are gradually reduced in the width direction. The dimension W of the reinforced composite pipe 21 is shaped so that it coincides with the position 24a of the outer end edge of the above-mentioned inner surface protection layer 24 .

[0072] Therefore, this reinforced composite pipe 21 is constituted by winding the strip-shaped resin mortar body 26 in a spiral shape from above the inner surface protection layer 24 and the inner surface FRP layer 23 so that the edges 26a, 26a are formed on the reinforced composite pipe 21. In the direction of the tube axis, the neat winding is consistent throughout the entire circumferential area.

[0073] In addition, in the reinforced composite pipe...

Abstract

The present invention provides a reinforced composite pipe with a uniform thickness and a manufacturing device for the reinforced composite pipe. The reinforced composite pipe can reduce the ratio of air bubbles mixed in the resin layer, thereby obtaining the desired watertightness and strength while making the composite pipe The ratio of supplied particles is increased, thereby reducing manufacturing costs. In the reinforced composite pipe (21) of the present invention, the resin mortar layer (22) obtained by impregnating the sand material (29a) (29b) in the resin solution and performing compression molding treatment is formed into a hollow tubular shape. The outer peripheral surface of the core material of the inner surface protective layer 24 of the resin layer is wound in a ring shape. The resin mortar layer (22) wherein is formed into a strip-shaped strip-shaped resin mortar body (26) along the axial direction of the outer peripheral surface of the cylindrical inner surface protective layer (24) adjacent to each other and spirally Shaped winding, so that the thickness is roughly uniform shape.

Description

technical field [0001] The invention relates to a reinforced composite pipe and a manufacturing device for the reinforced composite pipe. The reinforced composite pipe is used in distribution pipes such as water supply and drainage, agricultural water, and cooling water of hydroelectric power stations that require durability and corrosion resistance. A layer of resin is laid on the inner and outer sides of the reinforced composite pipe. Fiber-reinforced resin layers reinforced with glass fiber or the like, and resin mortar layers such as resin concrete are provided between these resin layers. Background technique [0002] Such as Figure 9 and Figure 10 The conventional reinforced composite pipe shown and the manufacturing apparatus of the reinforced composite pipe are well known (see Patent Document 1 and the like for example). [0003] Among them, as the manufacturing apparatus 1 of the reinforced composite pipe 11, it is well known that on the outer peripheral surface ...
