Description

[0001] The present invention relates to a connector having improved watertightness and rigidity by connecting a highly rigid sewage pipe manufactured with an environmentally friendly green property and a method of manufacturing the same,

The present invention relates to a connector having improved watertightness and stiffness by connecting a highly rigid sewage pipe manufactured with environmentally friendly green nature and a method of manufacturing the same. More particularly, the present invention relates to a connector having a high regeneration rate, Rigid sewage pipes which are formed by mixing and molding the entire surface of a cross crucible having a plurality of hollows or a profile having a hollow to provide high rigidity and simultaneously coat the inside and outside diameters of the profiles to further improve rigidity, The present invention relates to a method of manufacturing an eco-friendly green tire, which is capable of stably maintaining a watertightness by preventing rotation of a fastening bolt at a connection end connected to a tip end of the fastening bolt, Connecting port with high rigidity sewer pipe to improve watertightness and rigidity and manufacturing method thereof It relates.

Conventionally, in the case of a double wall sewer pipe used for a drain pipe of a synthetic pipe embedded in an underground, polyethylene (HDPE) is melted in an extruder so that a profile having a rectangular hollow is formed in the die, When the molten steel is first cooled and screwed into the winder device, the connecting member, which melts the polyethylene between the profiles, is supplied from the nozzle to form the sewer pipe.

However, since the polyethylene is not melted in the process of being melted in the extruder and it is not mixed properly, the raw material can not be supplied in a uniform state, so that it can not provide an accurate profile shape. So that the rigidity is lowered due to the hollow of the protrusion.

In addition, recently, an extruder nozzle device for molding a cross-shaped reinforcing bar inside a rectangular profile is registered as a patent registration No. 10-0392235 (registered on Jul. 2003, 09/03). In the profile, six hollows An extruder nozzle arrangement is provided which is capable of forming a so-called grate profile.

However, since the extruder nozzle device is designed to increase the strength by providing a nozzle device directly connected to the main body of the extruder and a cooling device inside the extruder, the profile of the grate profile is formed by using the extruded polyethylene directly connected to the extruder, The resin can not be supplied uniformly and accurately in the extrusion apparatus, and therefore, the hollow can not be properly molded, so that there is a limit in improving the strength.

In addition, since six hollows are formed and discharged, uniform cooling is not achieved even if the inside is cooled, and the hollow shape is broken because the molded state is in a semi-solid state.

In addition, since the hollow is uniformly formed only when a certain amount of resin is supplied to the core, a certain amount is not supplied to the core from the core member, the hollow is not uniformly formed, the thickness of the reinforcing rib is not uniform, So that the effect of improving the strength was not exhibited.

In addition, since the core is protruded forwardly and the thickness of the profile is thinned or thickened, the uniformity of the product can not be provided because the core is widened or broken due to the temperature of the polyethylene supplied at the time of molding.

In addition, in the Utility Model Registration No. 0243099 (registered on August 4, 2001), the polyethylene supplied to the cruciform space formed in front of the molded member after the polyethylene is supplied from the outside must be supplied uniformly, Since the resin is not connected to the cross-shaped space due to the structure connected to the side surface, the hollow and the reinforcing bar can not be formed uniformly.

In addition, since polyethylene is extruded immediately after it is melted in an extruder, it can not be uniformly mixed (agitated) and thus can not provide stable physical properties,

The protruding rectangular protrusion has a disadvantage that the thickness of the profile is thinned due to the heat source of polyethylene which is continued by the heat source of the polyethylene,

Meanwhile, in recent years, in order to impart greenness, when recycled raw materials are mixed in a range of 40% to 60%, green certification can be obtained and various recycling methods are applied. However, in the case of molding a profile by melt- When the molded cross-sectional profile of the cruciform barrel is molded and then finished with a sewer pipe, the bending strength is confirmed to be less than 700 MPa, resulting in defects that are easily deformed, and the tensile strength of the conventional polyethylene is maintained at about 20 MPa or less It was very difficult to form the sewer pipe of the stiffness,

Firstly, after the profile is extruded, it is cooled to a temperature of about 50 to 75 ° C while passing through a cooling device and spirally supplied to the winding device. In this process, polyethylene melt-molded at a temperature of 180 to 210 ° C is supplied Since the connection is made by the deviation of the temperature because the connection is made to the profile, it is not possible to connect properly due to the deviation of the temperature. Therefore, if the weather is cold during the winter or when the temperature is seriously lowered, There has been a drawback that the profile as a result of the thermal expansion coefficient and the shrinkage of the joint member significantly deteriorate the joining force for joining the profiles and thus the profile is separated and the function as the sewer pipe is lost.

Conventionally, a multi-wall sewage pipe and a double-wall sewage pipe according to the shape of a profile have a structure for connecting through a connecting hole at the front end, and a fastening bolt connecting to a pressure ring is formed on the outer surface of the main body, A KP connection is proposed to connect and connect the sewer pipe in a stable manner so as to be maintained.

However, the conventional connection pipe for connecting and connecting the sewer pipes can not stably maintain the watertightness by simply pressing the rubber ring. When the fastening bolt and the nut are tightly tightened for the purpose of maintaining the watertightness, There is a drawback that a tightening force is not provided due to the deformation of the lifting phenomenon caused by the tightening force at the interval between the tightening bolts of the pressure rings, and the head of the tightening bolt is centered on the body But it can not provide an accurate coupling state and is fastened in a state where it is rotated by about 10 to 30 ° to either side.
