Embodiment 1

[0033] A prefabricated pipe gallery. The pipe gallery is formed by connecting several pipe joints prefabricated in the factory on site. The pipe body of the pipe joint has a structural layer and an outer protective layer in the radial direction from the inside to the outside. The above structural layer is formed by winding multiple layers of wood and bonding and curing through flame-retardant epoxy resin. For planing wood such as veneer and laminated veneer lumber, the outer protective layer is made of epoxy resin. Its concrete preparation steps are as follows:

[0034] (1) Mandrel treatment: make mandrels with the cross-sectional shape and size required for the pipe gallery, and apply a release agent on the surface of the mandrels;

[0035] (2) Structural layer forming: After the planed veneer or laminated veneer is impregnated with flame retardant epoxy resin, it is spirally wound on the surface of the mandrel with a certain tension and angle, wound to the thickness of the ...

Embodiment 2

[0041] A prefabricated pipe gallery. The pipe gallery is formed by connecting several pipe joints prefabricated in the factory on site. The pipe body of the pipe joint has a structural layer and an outer protective layer in the radial direction from the inside to the outside. The structure layer is formed by winding the stalks of hemp plants in multiple layers and bonding and solidifying them through flame-retardant phenolic resin. The protective layer is made of polyurethane resin, and the inner surface of the tube is bonded with connecting components. Its concrete preparation steps are as follows:

[0042] (1) Mandrel treatment: make mandrels with the cross-sectional shape and size required for the pipe gallery, set a rubber ring at one end of the mandrel, and then apply a release agent on the outer surface of the mandrel covered with rubber rings;

[0043] (2) Structural layer forming: After drying the high-strength and high-toughness hemp skin stripped from the hemp stem,...

Embodiment 3

[0049] A prefabricated pipe gallery. The pipe gallery is formed by connecting several pipe joints prefabricated in the factory on site. The pipe body of the pipe joint has a structural layer and an outer protective layer in the radial direction from the inside to the outside. The structural layer is formed by winding multiple layers of straw and bonding and curing through flame-retardant polyurethane resin. The straw can be specifically selected from rice straw, wheat straw, sorghum stalk, corn stalk, etc. As a result, the inner surface of the tube is riveted with connecting members. Its concrete preparation steps are as follows:

[0050] (1) Mandrel treatment: make mandrels with the cross-sectional shape and size required for the pipe gallery, set a rubber ring at one end of the mandrel, and then apply a release agent on the outer surface of the mandrel covered with rubber rings;

[0051] (2) Structural layer forming: dry straw, wheat straw, sorghum stalk, corn stalk and oth...

Abstract

The invention belongs to the related field of municipal facilities and discloses a prefabricated type pipe rack. The prefabricated type pipe rack is formed by connecting a plurality of pipe joints, wherein each pipe joint comprises a pipe body which sequentially comprises a structural layer and an outer protective layer from inside to outside in the radial direction; each structural layer is formed by bonding and curing one or more multiple wound layers of wood, hemp stalks, rattans, straws, reed stalks and silvergrass stalks; and the outer protective layer is prepared from a fireproof corrosion-resistant material. The prefabricated pipe joints are connected on the engineering field to form the pipe rack, so that engineering quantity is greatly reduced, construction is convenient, engineering period is shortened and manufacturing cost is low; the pipe body is simple in structure, is convenient to process, the structural layer is taken as the main body structure of the pipe body, and is formed by winding plants materials such as wood with certain strength, hemp stalks, rattans, straws, reed stalks and silvergrass stalks, and raw materials are wide in source, are green and environmentally friendly and are reproducible.

Description

technical field [0001] The invention belongs to the technical field of municipal facilities, and more specifically relates to a prefabricated pipe gallery. Background technique [0002] The pipe gallery is a municipal facility built underground for laying municipal pipelines. It integrates various municipal pipelines such as electric power, communication, radio and television, gas, water supply and drainage, heat, etc., effectively uses the space under the road, saves underground space resources, and also prevents the irregular excavation of various professional pipelines, which will cause serious damage to the road. The impact caused by traffic and the surrounding environment has completely solved the problems of "zipper on the road" and "spider web in the sky". [0003] At present, whether it is cast-in-place or prefabricated, most of the pipe corridors use reinforced concrete structures. However, this structure consumes a lot of materials, requires a large amount of cons...
