Embodiment 1

[0011] Such as figure 1 As shown, a high-strength FRP sand-filled pipeline includes a fiber resin mixed layer on the inner wall 1 and the outer wall 2 of the pipeline, and a quartz sand resin mixed layer 3 composed of quartz sand and resin mixture is arranged between the inner wall 1 and the outer wall 2 of the pipeline. , fiber quartz sand mixed layer 4, the resin mixture is made by mixing resin and ground glass fiber, the ratio of the resin to ground glass fiber is 100: (10-15), the fiber quartz sand mixed layer is made of Quartz sand is mixed with glass fibers with a length of (1-5) mm.

[0012] The particle size of the quartz sand in the quartz sand resin mixed layer is 5-20 mesh, and the ratio of the quartz sand to the resin mixture is 90:(10-15).

[0013] The ground glass fiber is E(C)MG-200C type.

Embodiment 2

[0015] This embodiment provides a kind of high-strength FRP sand-filled pipeline, such as figure 2 As shown, the difference between embodiment 2 and embodiment 1 is that the sand-filled pipeline is provided with multiple layers of fiber-quartz sand mixed layers separated by layers of abrasive cloth.

Abstract

The invention discloses a high-strength glass reinforced plastic sand-doped pipeline. The high-strength glass reinforced plastic sand-doped pipeline comprises fiber-resin mixed layers on the inner wall and the outer wall of the pipeline; a quartz sand-resin mixed layer composed of quartz sand and a resin mixture, and a fiber-quartz sand mixed layer are arranged between the inner wall and the outer wall of the pipeline; the resin mixture is formed by mixing the resin and ground glass fiber, and the ratio of the resin to the ground glass fiber is 100:(10-15); and the fiber-quartz sand mixed layer is formed by mixing glass fiber which is 1-5 mm long with the quartz sand. The ground glass fiber is of an E(C)MG-200C type. According to the high-strength glass reinforced plastic sand-doped pipeline, the fiber-quartz sand mixed layer is formed by mixing the glass fiber which is 1-5 mm long with the quartz sand, the elongation at break of a sand-doped layer is increased, and thus, the adhesive strength and elongation at break of the glass reinforced plastic sand-doped pipeline are both substantially improved.

Description

technical field [0001] The patent of the invention relates to the technical field of FRP sand-filled pipelines, in particular to a high-strength FRP sand-filled pipeline. Background technique [0002] FRP pipes have a small specific gravity (1.8~2.1g / ㎝3) and high strength (≥300MPa), and their specific strength is much greater than that of steel pipes and cast iron pipes. Due to the addition of resin mortar in the middle layer of the pipe wall, the rigidity of the pipe is greatly improved, and it is suitable for various Soil environment and seabed laying. The current FRP pipe with sand inclusion requires a large amount of resin consumption, and at the same time, its mechanical properties are limited. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art and the actual situation, the present invention provides a high-strength FRP sand-filled pipeline, which includes a fiber-resin mixed layer on the inner wall and outer w...
