Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water control apparatus,

More particularly, the present invention relates to an apparatus for perforating a pipe, and more particularly, to an apparatus for performing perforation of a pipe in a safe manner, in which a cutter is inserted into a pipe during drilling, Apparatus and method.

In general, the perforation method is a method in which the piping is operated in order to install other piping in a fluid pipe such as a water pipe, an industrial water pipe, a plant facility line, and a drain pipe. The pipe to be added is installed with a static pipe.

The sanitary pipe includes a branch portion for exposing a surface of the pipe, and a wringing valve and a sandwich valve for controlling the flow of the fluid are installed in the branching portion.

And the drain valve or the sandwich valve may be provided with a perforation unit for forming a perforation hole in the pipe or another pipe into which the fluid branched from the pipe is introduced. Such a conventional continuous piercing method is disclosed in Korean Patent Registration No. 10-0891035 (piercing hole for a step-and-turn hydraulic method including a check valve type airtight cover).

In such a perforation method, a pontoon pipe is installed in a pipe to be drilled. The sanitary pipe includes a branch portion for exposing the surface of the pipe, and a branching valve or a sandwich valve for connecting the perforation unit to the pipe is installed at the branching portion.

And the perforation unit provided on the drain valve forms a perforation hole in the pipe with the drain valve or the sandwich valve opened.

Thereafter, with the drain valve or sandwich valve closed, the perforation unit is disconnected and another line is connected to the drain valve or sandwich valve, and after the other line is connected, the drain valve or sandwich valve is opened to flow the fluid.

1 to 3, a perforating device is drilled through a desired portion of the pipe for perforating the endless water. In this case, as shown in FIG. 1, (2) is generated. When the drill is drilled by the cutter of the drilling machine at the side drilling, a springback phenomenon occurs in which the cutting edge (2) of the pipe is pushed back with elasticity.

As shown in FIG. 2, when the pipe 1 is buried in the ground, the pipe 1 is not pressed into the ground and forms a compressed ellipse 1-1. Therefore, it is difficult to accurately mark the pore diameter (a) in the pipe in the pressed state, and when the pore is pierced, the springback phenomenon occurs due to the pressed state.

3, the lower end or the upper end of the cutting edge 2 to be cut and removed from the pipe 1 is not cut at the same time, and when a part is first cut, The cutter 3 is prevented from stopping the operation of the cutter 3 and the cutter 2 should be removed from the cutter 3, .

When a springback phenomenon occurs in the cutting piece 2 when the perforator 3 is punched by the perforator 3 as described above, the cutting piece 2 is separated from the cutter 4 There is a problem that the work is delayed for a long time or the work is not performed continuously. In addition, the above-mentioned phenomenon occurs in the same way in the upper hole or side hole of the pipe.
