Description

Water pipe filling materials and method of filling water pipes without breaking the wall

The present invention relates to a filling material for water pipes and a method for filling water pipes without breaking the wall, a novel formula material and a method for using the material for indoor repair.

Generally, the water pipes are buried in the walls or floors during the construction of houses to achieve the effect of protecting the water pipes;

However, after years and years, the buried water pipes may age and rupture causing water leakage;

At present, most of the repair methods for water leakage in the market are to directly cut open the wall to repair or replace the water pipes, but this method is extremely time-consuming and labor-intensive, and there are problems of noise and dust flying.

In view of the above shortcomings, the inventor believes that it is necessary to correct it. Based on his many years of experience in related technologies and product design and manufacturing, and adhering to the excellent design concept, he researched and created the above shortcomings. After continuous efforts, he finally achieved Introduced the water pipe filling material and the method of water pipe filling without hitting the wall of the present invention, hoping to correct the product structure and improve the excellent efficacy of the product.

The main purpose of the water pipe filling material and the wall-free water pipe filling method of the present invention is to provide a solution for repairing water pipe ruptures in a non-destructive manner.

In order to achieve the purpose of the previous disclosure, the present invention first discloses a water pipe filling material, the composition of which includes:

cement;

Water, mixed with cement in a predetermined ratio to form a cement slurry;

The cement additive is added to the cement at a predetermined ratio, and the composition of the cement additive includes cement waterproofing agent, seaweed powder and soap powder.

Next, the present invention also discloses a method for filling a wall-free water pipe using the above-mentioned water pipe filling material, which includes the following steps:

Disassembly procedure, after confirming the location of the leaking water pipe, turn off the water source, and then disassemble the exposed pipe fittings connected from the leaking water pipe;

Pressure measurement procedure, after pouring water into the leaking water pipe, observe whether the water pressure drops, the water pressure drops to confirm the water leakage, and then withdraw the pressure test water;

Infuse the pressure-maintaining program, pour the water pipe filling material into the leaking water pipe until the pressure remains constant, and then maintain the pressure for a predetermined time;

Extraction procedure, extracting the water pipe filling material in the water pipe;

Cleaning procedure, turn on the water source, let the water overflow freely to flush out the remaining water pipe filling material in the water pipe, and then turn off the water source after flushing;

To restore the procedure, reinstall the exposed pipe fittings that were previously removed, and finally turn on the water source again.

In this method, the water pipe filling material can be squeezed into the crack of the water pipe by filling the water pipe with the filling material and then holding the pressure for a period of time. The water pipe filling material is parallel to the drawing and flushing direction, so it will not break away from the rupture. After the water pipe filling material solidifies, the rupture can be sealed to achieve the leak-proof effect.

Compared with the need to cut open the wall in the past, this invention uses a specially prepared material formula to fill the cracks of the water pipe with the perfusion and holding pressure. It is a non-destructive repair method, which can save a lot of labor and time costs. There is no need to worry about the problems of noise and dust scattering. It is obvious that it has the potential to become the mainstream water pipe filling solution in the market, and it is a progressive creation.

The present invention relates to a filling material for water pipes and a method for filling water pipes without breaking the wall, wherein the composition of the filling material for water pipes includes:

Portland Type I cement;

For water, tap water can be used, and every 8kg of Portland cement is mixed with 10kg of water to form a cement slurry;

Cement additives, add 500g ± 30g of cement additives per 8kg Portland cement, the cement additives are composed of cement waterproofing agent 60-80wt%, seaweed powder 8-25wt%, soap powder 10-35wt%, and cement waterproofing agent , seaweed powder and soap powder are all commercially available products, and there is no special limitation on the selection.

[Please refer to the first picture] The method of water pipe filling is to use the above-mentioned water pipe filling materials, which includes the following steps:

Disassembly procedure (1), after confirming the location of the leaking water pipe, turn off the water source, and then disassemble the exposed pipe fittings connected from the leaking water pipe;

Pressure measurement procedure (2), connect the water delivery pump with a pressure gauge to the leaking water pipe, and then observe the water pressure after filling water. If the water pressure drops, you can confirm that there is a water leak. After confirmation, withdraw the pressure test water and disassemble the water delivery pump;

Filling pressure maintaining procedure (3), connect the cement pouring machine with a pressure gauge to the leaking water pipe, then fill the leaking water pipe with the aforementioned water pipe filling material until the pressure remains constant, and maintain the pressure for at least 1 hour;

Extraction procedure (4), let the cement pouring machine operate in reverse to extract the water pipe filling material in the water pipe;

Cleaning procedure (5), turn on the water source to allow the water to overflow freely to flush out the remaining water pipe filling material in the water pipe, and then turn off the water source after flushing;

Restoration procedure (6), put back the previously removed exposed pipe fittings, and finally turn on the water source again.

[Please refer to the first picture] In order to understand more concretely the method of filling the water pipe without hitting the wall, the following examples illustrate:

In general, the water pipes in the wall of a building are connected to a water tower or an external water source, and are also connected to the water outlets such as the faucet of the kitchen counter, the shower head of the bathroom, and the water tank of the toilet, so as to transport the water to these water outlets. The water pipe in the toilet wall leaks, and the personnel can know the water leakage from the water stain on the wall;

And firstly carry out the step (1) of the disassembly procedure, that is, first close the water outlet valve of the water tower or the water stop plug of the water meter, and then remove the water stop switch locked in the water pipe in the wall of the toilet. The wall is connected to the toilet tank by a hose, and the buried water pipe can be seen after it is removed;

Then carry out the pressure measurement procedure (2) step of the water pipe to confirm the water leakage, and then perform the perfusion pressure maintenance procedure (3) step. The purpose of this step is to use the pressure to squeeze the water pipe filling material into the water pipe rupture, so as to achieve filling purpose;

After the pressure is maintained, step (4) of the extraction procedure can be carried out. During this step, the water pipe filling material that is squeezed into the rupture is parallel to the extraction direction, that is, it will not be extracted;

After pumping out, proceed to step (5) of the cleaning procedure, that is, turn on the water supply of the water tower or water meter to allow the water to overflow freely, thereby flushing out the residue in the water pipe, and the water pipe filling material in the rupture is also parallel to the direction of water flow during the process without being flushed out;

Finally, proceed to step (6) of the recovery procedure, that is, to lock the removed water stop switch back to the water pipe.

[Please refer to the first picture] In addition, the cement additive in the water pipe filling material can contain 0.2-1.0wt% color masterbatch. Therefore, as long as the water flow is colorless after cleaning, it can be confirmed that there is no water pipe filling material in the pipe (except that which has been squeezed into the rupture) and stop.

What is described above is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention. That is to say, all equivalent changes and modifications made according to the scope of the patent application should still fall within the scope covered by this creation patent.
