The present invention integrates PVC tube and PC manhole by insert injection method instead of a separate fastener to prevent cracks, breakage and deformation due to impact, ground load, and shrinkage / expansion due to temperature changes. To prevent as much as possible,

An object of the present invention is to provide a manhole integrally formed with a connection tube made of a heterogeneous material capable of dispersing earth pressure or impact force applied to a connection portion between the manhole and the connection tube.

In order to solve the above problems, the manhole of the heterogeneous material connection tube molded integrally according to the present invention,

The rigidity of the inlet, drain and connection of the manhole is considered in consideration of the impact or load generated during the backfilling stage after the manhole construction, the impact applied to the manhole by vehicles or people operating after the construction is completed, and the ground load. To increase,

PE manhole and PVC connection pipe are each formed by insert injection molding.

In the process of integrally forming the connection pipe 20 and the manhole 10 by the insert injection method, the inlet 12 and the drain hole 13 of the manhole is formed to surround the inner and outer surfaces of the connection pipe 20 Among the inner and outer protrusions IP and OP, the inner protrusion IP is formed to be longer than the outer protrusion OP by a predetermined length d.

Further, in order to integrate the manhole 10 made of PE material and the connection pipe 20 made of PVC material, the joining groove which communicates the inside and the outside of the connection pipe with the end of the connection pipe ( 21) a manhole integrally molded with a connection tube of different materials, characterized in that it further comprises.

The biggest effect of the manhole formed by integrally connecting the heterogeneous material connection tube according to the present invention is to connect the inlet part and the drain part of the manhole by using a conventional standardized pipe tube as it is and integrally molded by the insert injection method. To increase the adhesion as much as possible

Instead of joining the connection pipe to the inlet and drain of the manhole with adhesive or other fixing means (e.g. clamps, bolts / nuts, etc.), it is integrally molded by insert injection method. Reduce the effects of swelling as much as possible, thereby preventing the occurrence of leakage at the junction,

As the inner protrusion formed on the outer wall of the manhole extends deeply into the inside of the connection pipe, the connection pipe between the manhole and the connection pipe is firmly supported from the inside to maximize the bondability (bonding force) between the manhole and the connection pipe. Can be increased,

Furthermore, by purchasing incinerated waste synthetic resin at low cost and commercializing it as a manhole, it is effective in creating added value and conserving the environment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, 2, the manhole is formed integrally the connection pipe of the heterogeneous material according to the present invention,

An inflow hole 11 is formed at an upper end thereof, and an inlet 12 and a drainage hole are provided on a side wall of the manhole 10 made of PE. A connecting tube 20 made of PVC material is formed by integrally molding an insert injection method in (13).

Referring to FIG. 3, the connection pipe 20 has a joint groove 21 for improving the adhesion between the water inlet 12 and the connection pipe and the connection between the drain port 13 and the connection pipe by insert injection molding. It is made to include more. In detail, by forming a plurality of joining grooves 21 communicating internally and externally on the outer peripheral surface of the distal end of the connection pipe 20 connected to the inlet 12 and the drain 13, the manhole 10 during insert injection molding. PE feedstock is filled into the coupling groove 21 to increase the adhesion between the water inlet 12 and the connection pipe and the adhesion between the drain port 13 and the connection pipe.

In the process of integrally molding the connection pipe 20 and the manhole 10 by an insert injection method, the inlet 12 and the drain hole 13 of the manhole surround an inner and outer surfaces of the connection pipe 20. Inner and outer protrusions IP and OP are formed. Circular connection grooves 12a and 13a are naturally formed by the inner and outer protrusions IP and OP.

In particular, the present invention is characterized in that in forming the inner and outer protrusions (IP, OP), the inner protrusion (IP) is formed longer than the outer protrusion (OP) by a predetermined length (d). This is because the manhole 20 is constructed in consideration of the impact or load generated in the backfilling step after the construction of the manhole 20 provided with the connection pipe, or the impact applied by the vehicle or person running after the construction is completed, and the ground load.
