In order to realize the purpose, the technical scheme of the utility model is that: seamless waterproof insulation connects includes: the heat insulation pipe comprises a heat insulation pipe, a heat insulation pipe PE outer protective pipe, an electric hot-melt wire net, a hot-melt wire, a PE sleeve and a heat insulation layer; the outer part of the heat preservation pipe is provided with a PE outer protection pipe of the heat preservation pipe, an electric hot-melt wire mesh is annularly laid at the end of the PE outer protection pipe of the heat preservation pipe, a hot-melt wire is installed on the electric hot-melt wire mesh, and a PE sleeve is laid outside the PE outer protection pipe; an insulating layer is arranged between the ends of the insulating pipes;

furthermore, the PE oversleeve is of a seamless integral structure, and the PE oversleeve and the electric hot-melting wire mesh are of a split structure;

furthermore, the PE oversleeve is laid outside the PE outer protective pipe of the heat preservation pipe and completely covers the electric hot-melting wire nets on the two sides, and the PE oversleeve and the PE outer protective pipe of the heat preservation pipe are closely attached and hot-melted and connected into a whole in an electric heating mode through a hot-melting wire;

furthermore, a distance is reserved between two ends of the electric hot melting wire mesh, and the hot melting wire is arranged at the ends of the electric hot melting wire mesh;

furthermore, the hot-melt wire is made of a copper wire;

furthermore, polyurethane is injected into a space formed by the PE sleeve and the ends of the heat preservation pipes on the two sides to form a heat preservation layer.

Furthermore, foaming holes are formed in the PE oversleeves positioned outside the heat-insulating layer, and hot-melt plugs are arranged at the foaming holes;

furthermore, the hot-melting plug is of a conical structure, and the conical hot-melting plug is in hot-melting connection with the foaming hole through heating;

when in connection, certain pressure needs to be applied to the hot-melt plug, and after the connection part is cooled and stabilized continuously, the foaming hole is connected with the PE oversleeve in a hot-melt mode into a whole.

The beneficial effect that adopts above-mentioned technical scheme to bring is: the seamless waterproof heat-insulation joint has no welding seam needing on-site welding, and the PE sleeve and the PE outer protective pipe of the heat-insulation pipe are in a hot melting integrated structure; the hot-melt plug is in a conical structure, has a larger welding area with the foaming holes and has a better sealing and waterproof effect.

The utility model discloses a split type structure has novel structure, simple installation, convenient to use, characteristics such as sealed water-proof effects are good.
