Description

Substituting pipe pipe replacement method and pipe structure constructed by the method {a piping to change method by groove digging method of construction and the hypocaust floor structure got fromit}

The present invention is a method for replacing an ondol pipe by a grooving method, which is a patent registration application No. 99-30668, which is filed by the applicant, and a grooving method using a more advanced new grooving method by replacing the ondol floor structure obtained therefrom. And it relates to the piping structure constructed in that way, more specifically, the on-pipe pipe, water pipe, drain pipe, etc. to replace the failure or when these pipes are old and replaced all over the new plaster pipe to the existing plaster mortar layer Only the part to be piped is cut and cut into a suitable depth and width to fit the pipe pipe's diameter with a concrete cutter to form a groove, and then a new pipe pipe is inserted into the pipe and the cement is used for the existing plaster mortar layer. Very simple to fill and finish mortar in a short time by filling the grooves piped to match the upper surface The grooving method pipe pipe replacement method for replacing the pipe pipe by the method and the pipe structure constructed by the method.

Some of China, including Korea, have been living with the habit of warming the floor and living in the ondol culture area.In the beginning, a bonfire was burned on the floor of a crypt or residence to heat the floor and remove moisture. The method of heating the ondol by laying ondol plates (shoes) on the floor of a residential area and burning them with a firewood is used to heat the ondol heating method as the fuel is changed from wood to coal → oil → gas. It is a situation that it is developed indirect heating method using circulating water that heats the ondol by circulating the heated hot water inside the ondol floor and circulating the heated hot water inside the ondol floor, which is difficult to be heated directly.

Therefore, in recent years, water pipes and drain pipes are piped to one side of the floor of a residential building, and then heat is insulated with an insulating material that prevents heat loss first, thereby minimizing heat loss, and heating the ondol pipe connected to the boiler that warms the heating water thereon. The underfloor was constructed in such a way that the pipes were spaced at a suitable interval and the above-mentioned pipes were covered with a plaster mortar layer to finish the pipes. When they are old, they should be replaced with new ondol pipes as they are directly related to their family's health.

In this regard, the existing method of replacing the ondol pipe firstly breaks the existing floor mortar layer 10 in which the old ondol pipe 30 is installed, which is old and abnormal, and completely removes the existing ondol pipe 30 and the existing floor mortar layer 10. After lifting, arrange new ondol pipes at appropriate intervals and form a plaster mortar layer on the upper surface and replace them with new ondol pipes, or, secondly, with the existing floor mortar layer 10 having old ondol pipes installed therein. A method of constructing a new ondol pipe that puts an ondol pipe on the upper surface of an existing bottom mortar layer 10 and forms a new finishing mortar layer is used. However, in the former case, the surface of the plaster mortar layer is very strong, so it is broken out. Was very difficult and cumbersome, and there were also problems with safety, such as cracks in buildings due to the impact. Balhamyeo, it will clean up construction waste is released in large quantities, so consuming replacement of the floor heating pipe work also takes a lot of time, money and had a lot of problems, such as the construction waste that causes pollution to occur in large quantities.

In the latter case, there is no hassle of breaking the plaster mortar layer and lifting all of them, but this is because the finishing mortar layer with the new ondol pipe is arranged on the existing plaster mortar layer where the old ondol pipe is installed. As the thickness of the material is considerably thicker, the weight is so heavy that the unreasonable load acts on the building itself, which greatly affects the life of the whole building, which inevitably leads to the risk of safety accidents. There was a problem, such as the inconvenience followed.

The present invention improves more completely by improving the technical contents of the patent application No. 99-30668, which is the applicant's prior invention, which has been made in view of the above problems, so that the work of replacing the old pipe pipe with a new pipe more quickly. In addition, the existing pipe line is detected in advance, and the existing pipe line is almost completely removed and the new pipe design is designed to maximize the heating effect after the pipe, improve the digging efficiency, and use the wet cloth to dig the pipe. Its purpose is to absorb the water or dust generated during work to keep the working environment and the indoor environment clean and to prevent the existing floor and the newly constructed floor from being completely adhered to each other after construction is completed. .

"Existing pipeline exploration process"

Hot water is inserted into the existing pipeline to detect the pipeline by heat detection, or when the pipeline is made of metal such as copper pipe, use a metal detector to accurately locate the existing pipeline.

To do this firstly; In order to prevent the work efficiency from being deteriorated due to the wear of work tools and the interruption of work caused by the coincidence of working position with the existing pipe, it is advantageous to avoid the existing pipe work. When the existing pipe is uniform, the existing pipe position is accurately dug to remove the existing pipe, and the new pipe is installed to protect the floor of the building and to prevent heat leakage along the existing pipe. For pants, third; If the existing pipe is an expensive renewable material such as copper pipe can be recovered, fourth; The purpose is not to damage the water pipes, etc. which are installed together on the floor.

"Existing Pipe Drainage Process"

Water remaining in the existing pipe is removed by blowing with high pressure air using a compressor, or by suctioning at a high pressure using a vacuum pump.

There are first things to do in this way; It is to prevent the problem of polluting the ceiling of the lower floor by leaking water in the existing pipe during construction, as well as polluting the working environment or indoor environment, as well as seeping into the floor and leaking to the lower floor. This is to prevent the water remaining in the existing pipe after construction and slowly evaporate the moisture on the floor.

"Plumbing position display process"

By selecting the pipe position to be installed correctly and marking it with a webbing line, it is to mark the pipe space uniformly.

"Wet cloth installation process"

Apply a wet cloth made by feeding an appropriate amount of water to a sponge or non-woven fabric and apply it to the area where the cutting blade on the bottom passes.

At this time, it is most important that the thickness of the wet cloth varies depending on the amount of water used during the digging process to absorb the water supplied to the saw blade during the work.

To spread the wet cloth as described above, first; In order to prevent water from penetrating to the bottom surface (heat insulation layer, heat insulation layer) by absorbing the water supplied to the saw blade during the cutting operation, one of the slotting operation, second; Absorbs fine dust such as dust generated during cutting operations to clean the work environment, minimizes work dust from contaminating the room, and minimizes contamination of the machine used for work, thus extending the service life of the machine. It is for.

"Linear pipe grooving process"

This process is a rail installation process that installs a rail to guide the linear movement of the equipment for straight line work, and a size that is easy to pipe the heating floor to the pipe while moving along the above rail (width is the size that fits the pipe pipe). ), And cutting the cut portion with a hammer drill or chisel, or digging with a scraper to dig a groove to a suitable depth (size to allow the pipe pipe to be buried and form a suitable mortar thickness thereon).

The type of equipment is not limited to any type of equipment, as long as it can cut and dig the floor. Therefore, you can use non-professional equipment such as hand grind or hand drill. And the rail that guides the linear movement of the equipment is also irrelevant as long as it can guide the movement of H-beams or other equipment that is used a lot.

"End Connection Pipe Groove Process"

This process is to connect the both ends of the straight grooved groove in a curved groove, install a rail for guiding the curved movement of the equipment for the curve work or rail mounting process for cutting the rail in a straight line to be connected to each other And, while moving along the above-mentioned rails, the heating bottom is cut into curves (width is about twice as large as the size of the pipe pipe) in a pipe or the outside is cut in a straight line and the inside is cut in a hat or oval. The cutting process is carried out, and the cut part is removed by a hammer drill or a chisel, or dug with a scraper to dig a pipe groove at a suitable depth (size to allow the pipe pipe to be buried and form a suitable mortar thickness thereon).

The type of equipment is not limited to any type of equipment, as long as it can cut and dig the floor. Therefore, you can use non-professional equipment such as hand grind or hand drill. And the rail that guides the curve movement of the equipment is also irrelevant as long as it can guide the movement of H-beam or other equipment that is used a lot.

And when grooving using a hand machine, it is easy to remove a lot of pipes in the inner part of the auspicious pipe where the pipe is bent enough to bend.

"Pipe pipe installation process"

In the above-described process, the pipe pipes to be installed are inserted deeply and installed in the pipe grooves formed with a suitable width and depth.

At this time, since the outer diameter of the pipe pipe and the width of the pipe grooves almost coincide, the pipe pipe is clamped in the groove so that no additional pipe pipe fixing means is required.

"Plumbing Home Water Supply Process"

By filling enough water to the existing bottom mortar layer that formed the pipe grooves, the existing mortar layer prevents the existing mortar layer from absorbing the moisture contained in the new mortar when filling the new mortar around the pipe pipe.

At this time, if too much water is absorbed by the existing mortar layer, and the remaining water may seep into the insulation layer, which may cause side effects. If water is too small, the moisture contained in the new mortar when filling the new mortar will be Absorbed by the mortar of the new mortar shrinks rapidly, causing a crack between the existing mortar and the new mortar.

"Aqueous coating solution for moisture escape prevention"

Applying an aqueous solution to the inner surface of the pipe mortar of the existing mortar that has been sufficiently watered to block the capillary hole of the existing mortar layer so that when the new mortar is filled into the pipe groove, the moisture of the new mortar is not absorbed into the existing mortar layer.

The aqueous solution used at this time can be used as long as it is an aqueous solution that can block the fine capillary formed in the existing mortar layer or any other water-soluble compound that can be combined with the existing mortar layer. The mortar layer and the new mortar layer are more perfectly bonded.

Applying an aqueous solution to the inner surface of the pipe groove of the existing mortar layer is a capillary phenomenon when the new mortar is filled because the fine capillary is blocked in the existing mortar layer. As the fine amount of the attrition shrinks rapidly and prevents a gap between the existing mortar layer and the new mortar layer, the existing mortar layer and the new mortar layer become one with each other.

"Mortal Filling Process"

When the above process is completed, the fastening cement is opened in the pipe groove to which the pipe pipe is piped and filled before the cement starts to harden.

It should be noted that it is important to fill the pipe grooves before the hardened cement hardens.

"Finishing process"

Finish the surface smoothly using metal plaster or hera before the hardened cement filled in the pipe groove is hardened by the above method. Grind the surface and finish.

The present invention completed in the above process is empty the inside of the existing piping pipe piped to the existing floor of the building and the curved pipe pipe investment groove is formed larger than the straight pipe investment groove to insert the pipe pipe therein, the pipe Fill the fastening cement into the buried groove where the pipe is installed to form the pipe structure so that the pipe pipe is buried.

In the present invention as described above, when the pipe pipe is broken or worn out, the existing pipeless mortar layer is not lifted out, but only the portion where the pipe pipe is piped into a groove having a suitable depth and width to suit the diameter of the pipe pipe. After the new piping is processed to prevent the cracking between the new mortar and the existing mortar, the rapid hardening of the cement pipe fills the pipe grooved with the piping pipe and finishes the construction. Not only does it take about 7 days to finish in a single day, but it also minimizes the occurrence of dust and noise when working, so that other workers can change their ondol pipes quickly and firmly in a simpler way. The cost is reduced and the building itself is not overburdened.

In addition, it is not necessary to break the mortar layer at the time of replacing the ondol pipe, but by cutting only the groove part, so that the floor of the building does not have to be severely impacted. It is a very innovative invention that is indispensable in constructions that replace ondol pipes, such as giving construction works with confidence.
