Embodiment 1

[0068] 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 .

[0069] 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.

[0070] In addition, in the reinforced composite pipe...

Abstract

The invention provides a reinforced compound pipe with uniform thickness and a manufacture device thereof. The reinforced compound pipe comprises an inner resin soaking stiffener layer, a resin mortar layer and an outer resin soaking stiffener layer, wherein the inner resin soaking stiffener layer is formed by winding fibers soaked with resin; the resin mortar layer is formed in a such way that a mixture mixed with the resin in sand materials or particle inorganic materials are limited in a thickness direction dimension and a width direction dimension to form strip-shaped resin mortar, the strip-shaped resin mortar is spirally winded on the outer surface of the inner resin soaking stiffener layer; and the outer resin soaking stiffener layer is formed by winding the fibers soaked with the resin outside the resin mortar layer. The inner resin soaking stiffener layer, the resin mortar layer and the outer resin soaking stiffener layer are laminated together.

Description

[0001] This application is the divisional application of the original application number 200510108550.6, the application date was September 29, 2005, and the title of the invention is "reinforced composite pipe and its manufacturing device" technical field [0002] 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 [0003] Such as Figure 9 and Figure 10 The conventional reinforced composite pipe shown and the manufacturing apparatus o...
