Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings.

[0019] As attached figure 1 As shown, the preparation process of a new type of steel-plastic composite pipe gallery includes:

[0020] 1) First weld the inner bracket (4) of the pipe gallery to the steel main body (1) of the pipe gallery;

[0021] 2) Wrap the polyethylene coating (3) on the steel main body (1) of the pipe gallery;

[0022] 3) Finally, the inner wall of the pipe gallery is sprayed with a fireproof coating layer (2), and the pipe gallery length can be made into 3m, 6m, 9m, 12m.

[0023] The main body of the new-type steel-plastic composite pipe gallery is steel pipes, the inner layer is sprayed with fireproof paint, and the outer layer is wrapped with polyethylene. The cross-sectional shape of the pipe gallery is semi-elliptical structure (vertical), semi-elliptical structure (horizontal), multi-prism structure (excluding quadrilateral), etc.

[0024] On the main body of the n...

Abstract

The invention relates to a manufacturing method of a novel steel-plastic composite pipe gallery. The manufacturing method comprises the following steps: (1) firstly welding a pipe gallery inner bracket (4) on a pipe gallery steel main body (1); (2) winding a polyethylene coating layer (3) on the pipe gallery steel main body (1); (3) finally spraying a fireproof paint layer (2) on the inner wall of the pipe gallery, wherein the length of the manufactured pipe gallery can be 3m, 6m, 9m or 12m. The manufacturing method of the steel-plastic composite pipe gallery is convenient in construction, short in construction period and low in cost. A main body steel pipe of the pipe gallery is high in strength; polyethylene is wound outside the pipe gallery, so the pipe gallery is corrosion-resistant and is good in corrosion resistance; the inner layer is coated with a fireproof paint, so the pipe gallery is good in fire resistance.

Description

Technical field [0001] The invention relates to the technical field of plastic processing, in particular to a preparation process of a novel steel-plastic composite pipe gallery. Background technique [0002] The traditional integrated pipe gallery (also known as common ditch) gathers some or all of various underground pipelines, such as electric power, telecommunications, heating, water supply, reclaimed water, gas, etc., which are scattered and independently buried underground, into the same underground pipe gallery for unified management. The pipelines in the trenches can be implemented in stages to avoid various losses caused by repeated excavation. At present, the comprehensive pipe gallery is basically made of cement, and the construction period is long. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art, and provide a new type of preparation process for a steel-plastic composite pi...
