And as an embodiment of the present invention to provide a connecting device of the present invention when connecting the PE reinforced spiral tube 16 as shown in Figures 6, 7, 8, 9 mortar on the outer tube 16 of the PE reinforced spiral tube The inlet 7 is formed and the inner tube 22 is assembled to form an inlet 7 'and an incision 8' in a circular or semi-circular arc shape in accordance with the outer tube 23 of the connecting device to be inserted and connected. After filling the cement mortar (10) through the inlet (7) to cure it provides a drainage pipe connecting device of the release standard of the present invention, wherein the reinforcement protrusion 20 is configured as a spiral winding as shown in FIG. PE spiral tube is also an invention applied to the connection device of the product in the configuration of the inlet (7) and the incision (8).

In addition, as an embodiment of the present invention, as shown in Figs. 10 and 11, it is also applicable to the case of connecting a drainage pipe such as a PE spiral pipe of the same size (dimension) bar between the inner surface 22 and the outer surface 22 'structurally (16) is configured to form a mortar inlet (7) in the connection portion of the outer tube (22 ') and to assemble the inlet (7) of the connecting socket 25 to each other and filled with cement mortar (10) If you cure and give back to provide a product of the present invention, instead of the connecting socket 25 constitutes the support grooves (6) (6 ') on both sides and spirally wound to the corrugated support (15) and the melting point (14) cement In the outer tube of the formwork composed of the inner and outer tubes that constituted the mortar injection space (A), the cement mortar input and cutting section (8) is configured in the circumferential direction in the inlet (7) and the outer tube (21) of the drainage pipe. After filling with mortar or foam (10) and curing for a certain time, Two people die is provided.

The present invention is used as a connection device for drainage pipes such as concrete fume pipes and PE reinforced spiral pipes used in civil engineering, building construction, etc., in particular, for the connection of heterogeneous standards, but conventional assemblies or separate injection products are used. The present invention is required to provide a product that provides a complete leak prevention bar as a product related to the connection formwork and connecting device of the heterogeneous standard, in particular connected to the drainage pipe (9), that is, the inner diameter (1 ') of the connection formwork (A) and The outer diameter (2 ') of the connecting connection formwork (B) is configured to fit almost the same, and the mortar (10) is filled by the cement mortar or synthetic resin foaming agent to fill the space of the formwork to be integrated. It provides a product that solves integration and solidification by filling and curing.
