Problems solved by technology

[0006] From a foreign point of view, although the advantages of the two are combined, the size of the direct production in the factory needs to be determined in advance, and the existing pipelines of other manufacturers cannot be fully utilized.
Moreover, only replacement and reinforcement can be carried out for pipelines under local conditions of poor use, and reinforcement construction for existing pipelines cannot be carried out.
[0007] Therefore, the pipeline technology in the prior art is not perfect enough, and there are many places to be improved.

Abstract

The invention provides a novel pipeline and a preparation method thereof, and belongs to the technical field of pipelines. The novel pipeline comprises a pipeline body. A waterproof film layer and a fabric layer are sequentially arranged on the outside wall of the pipeline body from the inside out. The fabric layer comprises a fabric cloth layer with meshes, a cellosilk layer and a compact fabric cloth layer, which are arranged from outside in sequence. The thickness of the fabric layer is 10-12 mm. The gram weight of the fabric layer is 900-1,200 g per square meter. The preparation method comprises the following steps: prefabricating a concrete blanket and laying the concrete blanket outside the pipeline body. The novel pipeline and the preparation method have the advantages that the compression resistance and the impact resistance of an original pipeline are improved, the corrosion resistance, the freezing resistance and the fire resistance of the original pipeline are improved, the preparation method is simple, and wide in application range, the processing cost can be reduced, and the processing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a pipeline preparation method. Background technique [0002] From a domestic point of view, there are currently two main types of domestic pipelines: one is to directly produce concrete pipelines, and the other is to directly produce special material pipelines, such as plastic pipelines and special steel pipes. [0003] From a foreign point of view, based on the use of the previous pipes abroad, there have been pipe designs in which resin is used inside the factory and the outer layer is wrapped with fabric-reinforced concrete (TRC). [0004] The above pipeline techniques: [0005] From a domestic point of view, the existing pipelines only use the pressure-bearing characteristics of concrete pipes and the transmission characteristics of special pipeline materials, and fail to combine the advantages of concrete pressure-bearing and the transmission medium advantages of special ...
