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 usually supplied through tap water pipes from the water treatment plant. ought. 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 such a large leak diameter, it is appropriate to shut off the main main valve and repair the damaged part in the case of large diameter. However, as most water pipes are passed to an area close to the water consumer, a large number of consumers are concentrated. 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, all the waste water in the water pipes is released at the same time. As a result, the so-called supply of water caused a situation that was uncomfortable. In order to prevent this phenomenon, the supply pipe of tap water is configured like a spider web, so that the entire tap water supply is not disturbed even if one part breaks or a breakdown of the water valve occurs. However, if the valve is too far around the broken water pipe to repair the damaged pipe, it is necessary to repair the water pipe in the absence of water stage. However, the freeze blocker developed in some developed countries was not very successful, and the freezing blocker was not only generalized because the structure was complicated and the operation price was astronomically expensive. In addition, accidents due to rupture of the water supply pipe or water pipe where the high water flow rate and high pressure supply water pressure exist should be promptly repaired, but when the position of the valve for the damage is located at a long distance, Even in the locked state, preparations were required to proceed with the operation, such as draining the filled water in the water pipe 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, if the water pipe is cut to install the water supply valve in the water flowed state, When the valve is pushed out to the outside cut off, the main body had a difficult problem in the case of the large diameter water pipe without locking the main water valve.

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.

According to the present invention, when a water pipe is ruptured in some sections and leaks occur, a water repelling device can be temporarily installed in the water pipe at the damaged part so that the water pipe can be quickly repaired without cutting off the entire water pipe in the corresponding section. The present invention relates to an apparatus and a method for repairing a water pipe that can be installed without cutting.

The present invention has been invented to solve the above problems of the prior art,

When the water pipe buried in the basement is damaged and leaks occur, the damaged parts can be repaired by installing the equipment for the order without cutting the water pipe at the front and rear of the most recent distance without breaking the main main valve. It is an object of the present invention to provide a device and a method for allowing a quick repair and installed water purifier to be utilized as a water dispense valve in need.

Each configuration will be described below with reference to the following examples.

Example 1

1 and 2 are perspective views illustrating an example in which the water pipe 4 is cut at right angles to the water flow direction to install the lower support part 1, the water blocking valve housing 3, and the water supply valve housing 7.

After deciding which part to install the water purifier 300 (water valve 36, water valve housing 7) (see FIG. 2), mark the position on the water pipe 4, and then In the state put in the lower portion of each water pipe (4), the upper high information steel plate (2) is assembled and fixed with a coupling device such as bolts 12 at both ends of the lower support part (1).
After excavating around the water pipe 4, the upper high-strength steel plate 2 is bolted to the flange wings 1a at both ends of the lower support 1 pushed under the water pipe 4 to reinforce the water pipe 4 While installing the cutting cloth factory to form a cutting hole opening 4a (see Fig. 4) in the water pipe (4). When the cutting punch opening 4a is formed, the water blocking valve housing 3 is placed on the central portion of the flange wing portion 1a of the lower support portion 1 and then bolted to the lower support portion 1 to fix it.
The lower support part 1 and the upper high information steel plate 2 are assembled and fixed to each other so as to reinforce the water pipe 4 itself so as to prevent a complete cutting accident of the water pipe 4 when cutting a section of the water pipe 4. The role is to give. In addition, by using the guide rod 11 formed on the top of the high information steel sheet (2) to be used when mounting or fixing the cutting cloth mill at the time of cutting water pipe (4).
As shown in FIG. 3, the lower support part 1 forms a flange wing portion 1a in the longitudinal direction in a semi-cylindrical body close to one half of the diameter of the water pipe 4, and the bolt hole 8 is formed at regular intervals. Processed. The bolt hole 8 is used for joining the upper high information steel sheet 2 or the water blocking valve housing 3 to the lower supporting part 1, and when assembling the bolt nut, it is processed as a simple bolt hole for assembling, but only with bolts. When the assembly is to be made, the female screw is to be machined into the inner surface of the bolt hole (8).
Inside the lower support part 1, a support packing 9 made of rubber is attached to prevent damage of the water pipe 4 due to the compression shock in the assembly fixing process and to increase the adhesion with the water pipe 4.
In addition, the lower base portion (1) was configured to form a uniform coupling force during assembly and to form the ribs 111 in a rib shape at regular intervals toward the bottom for reinforcement of the lower base portion (1) body itself.
In addition, the lower support portion (1) may be configured through a multi-assembly assembly rather than the usual half-division in case of large diameter.
The flange wings (1a) in which the bolt hole (8) is processed is manufactured in a structure that is not enough to assemble with the devices to be assembled on the top, but the width of the wings is wide in the central part where the water pipe (4) is cut and drilled In order to prevent the occurrence of trouble in the bolt coupling with the water blocking valve housing (3) made to exceed the width of the water pipe (4) in the future.
The lower portion of the lower support portion (1) to process the drain hole 10 to prevent the failure of the device due to the water remaining inside the support packing (9) during the assembly and maintenance process.
The upper high information steel plate 2 fixed to both ends of the lower support part 1 is composed of a body of a narrow semi-cylindrical body, and a flange wing part 2a formed for fixing with the lower support part 1. Is formed.
Of course, if the aperture is small, it can be processed as a u-band type.
When the lower support part 1 and the upper high information steel plate 2 are combined to reinforce the water pipe 4, the water pipe 4 is cut and drilled using a jig tool in which a cutting punching device such as an end mill is already coupled. As a result, the cutting drilling position of the water pipe 4 becomes the middle portion of the two upper high information steel plates 2 fixedly coupled to the lower support part 1, and the cutting depth is 1/2 the diameter of the water pipe 4. . However, the cutting drilling position and depth, and the cutting drilling width or diameter may be changed according to the shape of the order valve 36 to be described later.
The cutting drilling of the water pipe 4 is performed by cutting along the positions and lines previously marked by the jig tool. The cutting drilling mill may be a cutting tool or various tools such as saw blades and end mills. In this case, in order to prevent an electric shock due to tap water that begins to leak at high pressure from the water pipe 4 which has been cut and drilled, the driving motor may be preferably using hydraulic pressure or air pressure, and may use electricity. In addition, in order to prevent leakage due to high water pressure, it is preferable that the cutting cloth mill is selected to be waterproof.
The cutting width of the cutting perforation opening 4a is usually determined in consideration of the width of the order valve 36 (shown in FIG. 9), and the larger the pipe, the wider the cutting width should be. The change is made depending on whether the driving type is the vertical type or the rotary type butterfly valve type with the fixed shaft. In addition, in the case of the ball valve type, it will have a wider cutting perforation form, and in the case of the cylindrical valve 36, the cylindrical body should have a proper size of perforation.
If the cutting method is a rotary tool with a cutting edge using thick abrasive stone or an end mill, the work can be finished to the desired depth with the planned width.However, when using a cutting saw blade or a cutting machine using abrasive stone, In order to cut more than two times, water pipes 4 which are not removed remain inside the planned width which is already cut, and the water pipes 4 cut at right angles to the water flow direction are removed to remove the cutting holes 4a. In order to form, it is necessary to cut the portion corresponding to the cut width parallel to the water flow direction at the desired depth.
All cutting and cutting processes are to be carried out in a confined space in order to prevent work disturbances caused by excessive water pressure and increase in the amount of water ejected during the cutting operation.
In addition, the shape of the cutting hole opening 4a may be formed in a circular shape instead of perpendicular to the water flow direction. In this case, a circular cutting bite or abrasive stone having a size close to or equal to the inner diameter of the water pipe 4 is used.
When the cutting punch opening 4a is formed, the water passage blocking valve housing 3 is coupled to the cutting punch opening 4a.
The water blocking valve housing 3 formed the flange wings 3a to completely cover the cutting hole opening 4a and to be coupled to the lower support 1.
In addition, the pressing packing 20 is attached along the edge of the cutting surface of the cutting hole opening 4a, thereby applying a high pressure in the process of bolting the water blocking valve housing 3 and the lower support 1 to a high pressure. No leakage occurs outside the water pressure.
Of course, if the water pipe (4) is a steel pipe material other than the cast iron pipe or synthetic resin pipe, the water pipe (4) made of a separate steel pipe with a flange wing (3a) to connect the water blocking valve housing (3) to the existing order After fixing the water pipe 4 for the lower part by electric welding, the work of bolting the water-tight shield valve housing 3 to the flange wings 1a may be performed. In addition, when the water pipe 4 is a steel pipe or a stainless steel pipe and is easy to weld, the flange of the flange 1a, which is a main component of the lower support part 1, is symmetrically welded to the side of the water pipe 4 to shield the water passage. It may be possible to bolt the valve housing 3 directly. That is, the lower support part 1 should be understood as a term that implies all the independent functions having such flange wings 1a.
Of course, the tap water may be ejected through the cutting hole opening 4a in the process of bolting the water blocking valve housing 3 to the Hurenji wing 1a, but the water blocking valve housing 3 to be coupled in advance. By opening and combining the water blocking valve 31 (see FIG. 7), it is possible to prevent a coupling failure caused by water pressure and to block the water leakage by shielding the water blocking valve 31 after completion of the coupling.
On the other hand, when the order valve 36 is made of a butterfly valve type of the order valve housing 7 which is bolted to the upper portion of the water passage valve housing 3 using the valve flange wings 7a. The internal structure will consist of a rotating shaft and wing valve fixed simply to rotate.
Specifically, the inside of the water blocking valve housing 3 has a structure in which a top and bottom of a square corresponding to the width through which the water receiving valve 36 (refer to FIG. 2) can move up and down are penetrated, and a water blocking shield. A groove portion 18 (see FIG. 5) was formed on the side surface of the valve 31 to move back and forth. When the installation of the water blocking valve housing 3 in the cutting hole opening 4a is completed, the valve box 25 having the water blocking valve 31 embedded in the water blocking valve housing 3 is combined. do. Of course, the valve box 25 may be coupled to the lower support part 1 after coupling to the water shielding valve housing 3 in advance.

The valve box 25 coupled to the side surface opening of the water shielding valve housing 3 has a spindle handle 30 installed to protrude out of the valve box 25 as shown in FIGS. 6 and 7. When it is inserted into the spindle head 26 and rotates, the spindle 30 connected to the water blocking valve 31 is rotated and the water passing shield is formed along the recessed portion 18 formed in the water blocking valve housing 3. The valve 31 blocks the tap water coming up through the cutting hole opening 4a of the water pipe 4 inside the water supply valve valve housing 3 by moving backward.

Particularly, a drain valve 6 is installed below the water flow valve housing 3 so that the chip or scale separated from the water pipe 4 can be discharged to the outside during the cutting and cutting of the water pipe 4. During the process, some leaking tap water may be removed and discharged from the inside of the water blocking valve housing 3. In this case, since the water pressure inside the water pipe 4 is usually about 5 kilograms per square centimeter, the cutting chip may be easily discharged when there is an opening through the drain valve 6 near the cutting section.

In addition, the lower part of the water supply valve valve housing 3 is fitted into the cutting hole opening (4a) to be inserted into the water pipe (4) while forming a circular opening smaller than the internal diameter of the water pipe (4) to enable water flow. When the water level valve 36 installed in the combined fixed water level valve housing 7 is lowered to make the water level, the water level valve is operated by the guide function of the water level valve 36 and the high water pressure inside the water pipe 4. The valve guide frame 23 constituting the valve recess 21 (shown in FIG. 5) can be installed so as to prevent the 36 from being detached.

As shown in FIG. 5, the valve guide frame 23 is provided with a hard packing plate 22 at a lower portion thereof to fix the water blocking valve housing 3 to the lower support portion 1. By being pressed against, the water-retaining valve 36 is lowered so that no leakage occurs through the lower side or the side when the lowering is made.

Hurenji wing portion 17 is configured on the water-shielding valve housing (3).

In order to order the water pipe (4) it is coupled to the water valve valve housing (7) on the top of the water blocking valve housing (3).

The order valve housing 7 has an order valve 36 embedded therein, and an alternative form takes the form of a conventional gate valve.

However, the shape of the water valve 36 is a rectangular shape formed by cutting the cutting hole opening 4a at right angles to the water flow direction, or a circular shape that is perforated with or close to the diameter of the water pipe 4. It depends on whether or not and the shape of the valve guide frame 23 to be installed integrally with the water blocking valve housing (3) inside the water pipe (4).
In particular, when the valve guide frame 23 is not used, a rubber material with a cushion is formed around the valve 36 for the preparation in order to prevent the perfect order due to the scale or surface roughness of the inner surface of the water pipe 4. The valve packing 35 (see FIG. 9) was inserted to prevent leakage of water effectively when the water valve 36 was drawn and pressed inside the water pipe 4. Of course, after the cutting drilling process by polishing and polishing by using a grinding stone and a brush that rotates the scale and the surface inside the water pipe (4) through the cutting hole opening to increase the adhesion of the valve in the future or joining the valve guide frame (23). You can go out.
In addition, if the water-sealing valve housing (3) is not used for the distillation use, but simply used for the purpose of the water for the maintenance time it will be possible to work even without the valve guide 23 is installed.
In the drawings, reference numeral 14 denotes a packing, 18 denotes a cover plate covering an upper opening of the water blocking valve housing 3, and 5 denotes a handle for raising and lowering the valve 36 for water.

Example 2

FIG. 10 is a cross-sectional view illustrating an example in which a circular perforation part having a size close to or equal to the inner diameter of the water pipe 4 is formed on the water pipe 4 by applying the second embodiment of the present invention. After installing the lower support part 1 and the water blocking valve housing 3 in the water pipe 4, a circular drilling part is formed in the water pipe 4 using a cutting cloth mill, and then the water blocking valve housing 3 In order to block the tap water by advancing the water shut-off valve 31 in the), the cutting cloth mill is removed.

The through part connected from the lower part of the water blocking valve housing 3 to the upper part is formed in a circular shape having a size close to the circular hole which drills in the water pipe 4.
After the water-shielding valve housing (3) to the upper coupling unit 300 is bolted,

The ordering device 300 is configured of the order valve housing 45 and the operation cylinder 38, the order valve housing 45 inside the order valve 43 is built in the operation cylinder 38 It is composed of a general internal device using hydraulic pressure.

The lower rubber packing 46 is manufactured to be installed in a slightly hemispherical shape. The lower rubber packing 46 is positioned below the water supply valve 43 and is inserted into the water pipe 4, and then is strongly pressed against the bottom surface of the water pipe 4. This will prevent the leakage of water.

A cylindrical rubber sleeve 44 made of rubber or synthetic resin having a certain thickness and excellent in stretching and restoring force is formed on the outer circumferential surface of the valve for the valve 43. The upper part of the valve for valve 43 is fitted to the cylinder shaft 800, and is configured to be movable separately. A rubber O-ring 59 is inserted into the outer circumferential surface thereof, and its outer diameter is close to the cylindrical rubber sleeve 44. The pressure piston 41 is configured to prevent the cylindrical rubber sleeve 44 from escaping to the upper side during the operation of the water valve 43.
In the second embodiment configured as described above, in order to operate the water valve 43, the water-receiving valve housing 3 of the water-receiving valve valve 3 is reversed, so that the water pipe 4 perforations and the water-receiving valve housing ( The cylinder shaft which is a component of the order valve 43 by using a cylinder operated by a pressure fluid or rotating the operation handle formed by the well-known gate valve structure of the order valve housing 45 after securing the passage between 45). It will descend 800.

At this time, the water level valve 43 is lowered and the lower rubber packing 46 is compressed to the lower inner circumferential surface of the water pipe 4, and then the pressure piston 41 is further lowered, and the cylindrical body under the pressure piston 41 is lowered. The rubber sleeve 44 is inflated in the lateral direction while being contracted downward, thereby filling the inner circumferential surface of the water pipe 4 to secure watertightness. At this time, the valve valve shaft 53 made of soft plastic or rubber also helps the cylinder rubber sleeve 44 of the valve 43 to be inflated by inflating as the contraction in the longitudinal direction occurs. Given.

The rubber o-ring 59 installed on the top of the water valve 43 serves to facilitate the operation of the water valve 43 while preventing leakage to the upper portion of the water pipe 4.

Example 3

Example 5

Fig. 22 is a perspective view drawn for explaining the fifth embodiment of the present invention.

The upper cover housing 88, which is made to cover and fix the entire lower support part 1 in a state in which the upper high information steel plate 2 is not installed in the above-described lower support part 1, is installed. In this case, the lower support part 1 and the upper cover housing 88 are configured to have a sufficient length, and even if the water pipe 4 is completely cut, it is to be coupled in a structure that does not cause a rolling phenomenon or leakage. Of course, when the water pipe 4 is completely cut, in order to prevent the sliding phenomenon, when the material of the water pipe 4 is a weldable material such as a PE pipe, a steel pipe, or a stainless steel pipe, the water pipe 4 may be made of the same material as the outer periphery of the water pipe 4. After the O-ring is welded, a method of processing and coupling the anti-rolling O-ring groove at the position where the O-ring is inserted into the lower support part 1 and the upper cover housing 88 may be applied.

The upper cover housing 88 is configured to allow a conventional bolt coupling that can be configured to the water blocking valve housing 3 therein as described in the first to the fourth embodiment therein and to install the water repellent device 300 thereon. The flange part was installed and the top cover housing 88 was able to be coupled. The inside of the upper cover housing 88 formed an opening for a valve, or a cylindrical valve or a ball valve so that the valve 43 for operation can be operated up and down.

In the present embodiment, as shown in FIG. 23, the lower support part 1 and the upper cover housing 88 are coupled to both positions around the water pipe 4 at the position where it is broken and leaks or a new valve needs to be mounted. In the state where the water passage valve 31 is retracted, the cutting drilling tool is coupled to the flange portion installed in the upper cover housing 88 to start the cutting drilling. In the case of cutting drilling, cutting drilling is made to a size larger than the diameter of the water pipe 4, and the water pipe 4 is completely penetrated inside the lower support part 1 and the upper cover housing 88 by passing through the lower part of the water pipe 4. It remains cut.
Of course, in the case of thick cast iron pipes, synthetic resin pipes, etc., it is possible to maintain the state that is not completely cut.
The lower support part 1 has a lower cylindrical cylinder 550 having a cutting hole size, and a separate guide recess for lowering the lower support part 1 and the upper cover housing so that the valve 43 can be operated in a watertight manner. 88) and installed.

At this time, using a separate cutting tool may simply cut the water pipe (4) to a constant width perpendicular to the water flow direction.

The water supply valve housing 450 was re-installed and fixed at the position where the cutting punching mechanism was installed in the state where the water blocking valve was advanced to block leakage to the outside, and then reversed the water blocking valve 31 for the water The tap water is ordered by operating the valve 43.

At this time, due to the frictional resistance acting on the surface of the water pipe (4) in the buried state and the firm coupling of the lower support portion (1) and the upper cover housing 88, the lower support portion (1) and the upper cover housing 88 to the outside The phenomenon of being pushed out can be suppressed. In addition, in order to prevent the lower support portion 1 and the upper cover housing 88 from being pushed outwardly, the latch hole formed at the same position when the lower support portion 1 and the upper cover housing 88 are coupled to each other. And the support rod 83 is driven deep into the ground through the clasp hole, and the lower support part 1 and the upper cover housing 88 are coupled to the support rod 83 by a pipe band to fix the lower portion together. The supporting part 1 and the upper lid housing 88 are not separated from the water pipe 4 from the high water pressure. Alternatively, as shown in FIG. 20, the support rod 83 can be fixed by driving the support rod 83 into the ground as described above in the water shutoff valve housing 3 and the lower support 1, and as another method. As shown in FIG. 21, a fixing pipe band 700 having a separate wide width is fastened to the water pipe 4, and the turnbuckle 71 is disposed between the fixing pipe band 700 and the upper fixing reinforcing plate 2. By installing this may be tensioned through the turnbuckle 710 so as not to be separated from the water pipe (4).

In addition, by forming a separate tap water outlet in the upper cover housing 88 to form a piping that can bypass the damaged part by bypassing the water-retaining valve 43, the water pipe (4) is used for tap water in the maintenance process The tap water can be supplied without any problem.
