Conventionally, when installing a connection pipe on the side of the sewage main pipe, a circular hole was generally drilled and a branch socket or saddle was attached thereto.

Circular hole uses perforator or jig-saw, electric installation is essential, and jig-saw is difficult to use because it is difficult to use gardening and it is inclined or crushed after drilling. . In addition, when the inlet hole is drilled in the pipe, the size of the hole is limited due to the safety of the pipe structure.

In particular, the circular washer having a pipe curvature is larger than the inlet hole when the branch pipe socket is attached to the inner surface of the inlet hole by a round washer having a curved surface. Therefore, if the diameter is different, the same washer has to be replaced.

In order to solve the above-mentioned problems, the present invention is to reduce the inlet hole size (diameter) formed on the side of the main pipe by forming a cutting width shorter than the diameter of the connecting pipe on the circumference of the main pipe and at the same time forming a lengthwise length of the connecting pipe, In order to make the branch pipe socket the same as the main pipe sewerage, the internal cross-sectional area is the same as the main pipe cross-section so that the development of branch pipe socket attachment device having the same effect as the deformed T pipe and positive T pipe structure is a technical problem. Another problem is that the width of the inlet hole drilled in the main pipe is narrow and lengthened in the longitudinal direction, thereby ensuring structural stability of the pipe due to the inlet hole drilling, and at the same time, there is no expensive drilling machine or equipment when drilling the inlet hole (Jig-Saw). Or design a geometric inlet hole for easy operation with a hacksaw, cutter, etc., and an inner washer covering the inner surface of the inlet hole. By narrowing the width of the blade with the curvature of the inner washer that is not cut and the curvature of the inner washer that has been cut down, the development of the inner washer that can be used in common even though the pipe inner diameter is different is a challenge, and one pull (one-touch) The technical development that the present invention intends to achieve is the development of a technology that prevents the inner washers that reach the inner surface of the pipes from being touched by the branch pipes, being stuck or plugged or pulled down, and the watertightness of such branch pipe socket attachments. It is a task.

In addition, when using Patent Registration No. 0531157, a plurality of bolt holes of the branch inner pipe protrusion and the protruding pipe of the inner washer are bisected. To the formed female thread, bolted to the protruding frame bolt hole and screwed to the female thread. When using Patent Application No. 10-2005-0086228, the width of the bilaterally symmetrical inner surfaces of the lower branch pipes of the box shape is widened upward. The inner washer protruding tube is made to be inclined and the bisected inner washer protruding tube is opened to prevent the inner washer protruding tube from being pulled out downward, and when using Patent Application No. 10-2005-0094247, the mutually symmetrical inner surfaces of the lower branch branch in the form of a box A plurality of protrusions formed on the inner side of the protruding tube to open the protrusions on the side grooves of the protruding pipes, and when using the patent application No. 10-2006-0074029, a plurality of inclined grooves and inner washer protrusions formed on the inner surface of the branch pipe Pull out the inner washer protruding pipe from the inside of the branch pipe by inserting a wedge into the wedge hole at the side of the pipe and fastening the birds to the pipe. Each of the other branch tube socket device is not a branch structure different tube socket device that prevents using more engaging portions (44, 55) is included in the present invention. Packing for watertightness is preferably to use the watertight method of Patent Application No. 10-2004-0075290 and Patent Application No. 10-2006-0068953, which is curved on both sides that are in close contact with the entire periphery of the inner surface 620 of the pipe inlet hole. Box-shaped packing center portion 72 having the inner surface portion 73 and the four-sided inlet hole 650 in the form of grooves or grooves 74 or pleats 77 are formed on the inner or outer surface of the box-shaped packing or the box-shaped packing, and in the same direction The box-shaped packing 70 formed of the packing outer surface 71 which is the packing upper end of the lower portion of the lower branch pipe is integrated with the packing outer surface 71 of the box-shaped packing inner surface portion 73. ) Is press-sealed between the inner washer wing piece 310 upper surface and the pipe inlet hole inner surface 620. In addition, the packing outer surface 71 or the packing central portion 72 and the packing outer surface 71, which are upper ends of the box-shaped packing 70, are press-tightly packed between the lower inner branch lower inner surface and the inner washer square projection tube. Even if the outer surface portion 71 is separated from the branch pipe, the watertight seal can be watertight, and the packing outer surface 71 or the packing center portion 72 and the packing outer surface portion 71 can be pressed against the lower surface of the branch pipe 285 to be watertight.

In addition, the quadrilateral inner washer is a bisected inner washer that is cut up and down when inserted into the quadrilateral inlet hole, and may form a bent portion or a hinge 500 at the end of the wing piece, and connects a tensile line 6.
