Inserting to block or control the insertion step (S150); a replacement step (S160) of inserting the disk unit into the transfer path of the pipe to block or control the transfer path of the pipe, replacing the replacement pipe or replacing the disk unit as the replacement target; a separation step of separating the driving means or the gate valve from the pad part when the replacement of the replacement object is completed (S170); and a fixing step (S180) of fixing the detachable adapter part to the upper part of the cover part to prevent the lifting part to which the disk part is coupled from being separated from the cover part; is made including

The installation step (S110) is a step of installing a plurality of flanges 111a, 111b, 112e on the outside, and the pad part 110 having a transfer path formed therein, respectively, around the outer circumferential surface of the pipe 10 through which the fluid or gas is transferred. to be.

The pad part 110 has a plurality of flanges 111a, 111b, 112e on the outside, and a transfer path is formed therein, respectively, and is installed around the outer circumferential surface of the pipe 10 for transporting a fluid or gas. transport gas.

Specifically, the pad part 110 is made of a metal material or a synthetic resin material, and is divided or not divided into a half-pipe-shaped upper pad part 111 and a lower pad part 112 based on the center as in the present invention. is formed

The installation relationship between the pipe 10 for transporting a fluid or gas and the pad part 110 is a pipe 10 to the flanges 111b and 112e formed on both sides of the plurality of flanges 111a, 111b, 112e formed outside. These are installed to be connected to each other, or the pipe 10 may be inserted and installed around the outer circumferential surface of the pipe 10 , ie, inside the pad part 110 , as in the present invention.

The pad part 110 is formed in a flat bottom of the flange (112e) formed on both sides of the plurality of flanges (111a, 111b, 112e) formed on the outside, so that the floor of the installation site has an uneven floor such as stones or sand. It is possible to prevent a safety accident of a worker working nearby by preventing the pad part 110 of the weight chain from being shaken at the same time to ensure that it is erected stably without being shaken.

The flanges 112e formed on both sides of the pad part 110 have a flat lower portion so that they can be erected stably at the installation site with an uneven floor, and can easily support a separate splint used at the installation site.

The pad unit 110 includes an upper pad unit 111 and a lower pad unit 112 .

The upper pad part 111 is coupled to surround the upper outer peripheral surface of the pipe 10 for transporting a fluid or gas in a half-pipe shape, and flanges 111b are formed at the upper center 111a and both ends, respectively.

A plurality of holes are formed in the upper pad portion 111 so that a plurality of screws serving as fixing means can be inserted in a portion formed flat between the flanges 111b formed at both ends, respectively.

In the present invention, the upper pad part 111 is exemplified that flanges 111b and 112e are respectively formed at both ends like the lower pad part 112 to be described below, but in some cases, flanges 111b, 112e) may not be formed.

The upper pad part 111 and the lower pad part 112, which may not have flanges formed at both ends, may be provided with pressing means and contact means capable of pressing or closely contacting the circumference of the outer circumferential surface of the pipe at both ends.

The pipe 10 inserted into the pad part 110 by the pressing means and the contact means is not shaken even by vibrations generated in the process of drilling using a perforator.
