The present invention relates to a non-cutting order device for repairing water and sewage pipes, and more particularly, when the water pipes buried underground are leaked and leaks occur, the tap water is normally supplied to a concentrated consumer without blocking the main main valve. It is possible to repair damaged water leaks in a short time without repairing water, and to repair damaged water leakage accidents of water pipes in a short time. Also, the installed water drainage device can be used as a distillation valve to maintain quick and economical water pipes. And to provide a repair effect, and in addition to the structure of the order to significantly improve the order to maximize the order effect, thereby to significantly improve the quality and reliability of the product.

First, it is to be understood that the present invention is a complementary and improved invention of the patent application No. 2002-76086 (Publication No. 2004-48281) (name: non-cutting order apparatus and method for repairing water pipes), which is filed by the applicant. .

As is well known, one of the essentials in each home, business building, and industrial site is water, which uses groundwater developed for direct supply from the site, but is generally used for treating water pipes. It is supplied through. Water pipes are usually made of cast iron pipes or steel pipes, and some of them are stainless steel pipes or synthetic pipes. Commonly used cast iron pipes have small diameters ranging from 50 millimeters to several hundreds of millimeters in diameter. Almost all of them are buried in the ground. These water pipes are subsidence of soil, the presence of uneven earth pressure, and the temperature of winter ground. Frequently, breakage leaks were caused by freezing due to the fall of. In the case of large diameter, it is appropriate to shut off the main main valve and repair the damaged part in case of large diameter.However, as most water pipes are passed to an area close to the water consumer, When the main valve is shut off, these concentrated consumers must bear the inconvenience caused by the water shortage, and when the water flow is started by opening the valve that has completed the repair of the damaged water leakage and shut off the water, It was very inconvenient to go to the consumer, and so-called supply of water occurred. In order to prevent this phenomenon, the supply pipe of tap water is configured like a grid of spider web so that the entire tap water supply is not disturbed even if any part breakage or breakdown of the water valve occurs. However, if the water level valve is too far around the broken water pipe to repair the damaged pipe, the water pipe needs to be repaired in the absence of water, and many requests for repair of the water pipe have been considered. However, the freeze protection device developed in some developed countries was not very successful, and the structure was not complicated, and the operation price of the freeze was not generalized because the purchase operation price was astronomically expensive. In addition, accidents caused by rupture of water supply pipes or water pipes with high water flow rate and high pressure supply water pressure should be promptly repaired. However, when the position of the water supply valve is located at a long distance, In the state, I had to go through the preparation process for working for a considerable time. Even if the work is ready, if the work is to be carried out without water in the water supply area, the water supply valve is cut off due to the high water flow rate and high water pressure. In the case of a large diameter water pipe, the main body had a difficult problem when the main order valve was not locked. In addition, the technology for forming the branch pipe in the main main pipe in the absence of the stage has been developed and operated, but this technology is effective for the branch pipe work, but there was a lack of technology to replace the main valve.

Referring to the operation and effect of the non-cutting order device for repairing the water and sewer pipe of the present invention configured as described above are as follows.

The non-cutting order device for water and sewage pipe repair applied to the present invention cuts the water pipe at a position before and after the recent distance around the damaged part without blocking the main main valve when the water pipe buried underground is leaked. In order to repair the damaged part by installing and ordering the equipment for each order in the state not to be described in more detail below.

First, when the water pipe is broken, the excavation work is usually performed by mobilizing the excavator, and when the leaking part is confirmed and the part is broken, the excavation is further excavated as long as the section can be installed around the damaged part. After securing a sufficient working space in the basement will be installed the order of the present invention as shown in Figs.

The order unit 50 applied to the present invention is initially located inside the packer cylinder 30 as shown in FIG.

When the operator turns the handle 44 in this state, the spindle 43 rotates together by the rotation of the handle 44 (or the spindle 43 automatically rotates by the hydraulic mechanism), and the spindle By the rotation of 43, the order portion 50 is lowered.

That is, the threaded portion formed on the outer circumferential surface of the spindle 43 is fastened to the female screw 52c formed at the center of the order portion 50. When the spindle 43 rotates forward and reverse, the female thread 52c rotates the spindle 43 Ascending and descending up and down along the threaded portion formed on the outer circumferential surface of the) as a result, the order unit 50 is moved up and down in the interior of the packer cylinder (30).

In addition, at this time, the housing 52 provided in the order part 50 rotates the spindle 43 because the male screw 52d formed at the lower end thereof is fastened and fixed to the nut 53 installed in the expansion packer 51. As a result, the entire order portion 50 moves up and down.

In addition, the protrusions 50a protruding from both ends of the order part 50 in the process of the order part 50 moving up and down in the packer cylinder 30 are rail grooves formed in the packer cylinder 30.
