What is a grouting orifice pipe and what is a grouting hole sealer

Grouting pipe] Consultation**: 15864931222Manager Li grouting pipe is a kind of embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints, and voids between ground walls in concrete.

It is very suitable to install a grouting pipe between the joints of the new and old concrete. When water seeps into the joint, it can be sealed by injecting slurry into the PVC port set on the surface. The appropriate time for grouting can be carried out after the end of concrete curing.

Leaking seams can also be permanently sealed in this way. Injecting grout into an embedded grouting pipe can seal construction joints, cold joints, pipe leaks, and joints between ground walls.

Features: The grouting pipe is divided into one-time grouting pipe (CCLL-Y grouting pipe, IT grouting pipe, CCLL-Y full-section grouting pipe.

and repetitive grouting pipes (CCLL-D grouting pipes, CCLL-D full-section grouting pipes).

The one-time grouting pipe can only be grouted once and cannot be reused.

The repetitive grouting pipe can be reused many times, and the core and outer wall of the pipe need to be rinsed clean after each use.

Specification: Disposable grouting pipe.

Inner diameter: 8mm; Outer diameter: 12mm; Inner diameter tolerance: ??Length per roll: 120m.

Repetitive grouting pipes.

Inner diameter: 8mm; Outer diameter: 20mm; Inner diameter tolerance: ??Length per roll: 90m.

Pros:1Simple installation, supplied as a set;

2.The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (the longest length of the grouting outlet is recommended not to exceed 6 meters);

3.No special installation equipment is required;

4.The grouting time can be arbitrarily selected;

5.When the grouting is injected inward under the action of appropriate pressure, the slurry grouting pipe liquid can be kept evenly filled with the entire pipe;

6.The system allows for grouting at relatively low pressures; The grouting pressure is.

7.The installation will not affect the characteristics of the building grouting pipe itself;

8.The installation or grouting process does not endanger the concrete;

9.After grouting, it can ensure a permanent seal;

10.If there is no leakage, you can do without grouting.

Before grouting into the hole, a pipe (iron pipe, plastic pipe, etc.) is embedded in the orifice to connect the grouting pipeline, and the embedded pipe is called the grouting orifice pipe.

In order to prevent the grouting pipe from being flushed out during grouting and to guide the drilling of the grouting hole, a section of steel pipe is generally embedded in a certain depth of the grouting hole orifice, and this steel pipe is called the orifice pipe.

The grouting hole sealer is based on the "two walls and one injection" grouting sealing process under pressure, the grouting pipe is connected with the grouting pump, the grout quickly enters the two capsule bags because of the grouting pressure, so that it expands rapidly, so that the outer layer of the capsule is fastened on the inner wall of the coal seam hole, and the inner layer is fastened to the outer diameter of the extraction pipe, so that the two ends of the hole sealer are sealed, when the pressure value reaches a certain value, the blasting valve begins to burst, and the slurry fills the middle of the two capsule bags, so as to achieve multi-layer pressure sealing, after the grouting is completely solidified, Gas extraction is carried out through a gas extraction pipe.

It was jointly developed by China University of Mining and Technology and enterprises.

The main features of the grouting sealer:

Active support. After grouting the capsule, it can form an effective support for the borehole, so that a high-stress area can be formed around the borehole in the sealing section, so as to avoid continuous cracks and air leakage channels after the hole is sealed.

Pressure grouting. The grout can be drilled into the cracks of the hole wall, the cracks around the borehole are closed, the permeability is reduced, and the initial air leakage channel is blocked.

The length is adjustable. The length of the mine hole sealer can be adjusted according to the actual drilling situation in the underground.

A method of waterproof construction, mainly for the water seepage problem of the ground roof wall that has been formed, the method is to punch holes first, and then use a grouting machine to inject waterproof slurry.

Summary. It is the waterproof glue squeezed into the leakage gap through the high-pressure grouting machine, to achieve the purpose of plugging the leakage, do not believe the advertising on the Internet, these people are Anhui people in all parts of the country have specialized in waterproof leakage fraud, at the beginning of the valuation, only tell you how much a pound of glue, how much to use, the routine of you, so that you feel that you can't spend much amount, the result is dozens of hundreds of pounds, the price is thousands or even tens of thousands of yuan, the result is still leakage.

It is a kind of direct hole without smashing the tile, through the high pressure generated by the grouting machine, and the glue is filled into the crack with sensitive glue, and the glue penetrates into the crack like a water rent. Don't look for the Internet, these people are Anhui's leak plugging gang, pit dead people! Look for a master who has a physical store.

Excuse me, but please go into more detail?

It is the waterproof glue squeezed into the leakage gap through the high-pressure grouting machine, to achieve the purpose of plugging the leakage, do not believe in the advertising on the Internet, these people are Anhui people in all parts of the country have specialized in waterproof leakage fraud, began not to estimate the hail Qi roll, only tell you how much a pound of glue, how much to use, the routine you, so that you feel that you can't spend much amount, the source of the surplus result is dozens of hundreds of pounds, the price is thousands or even tens of thousands of yuan, the result is still leakage.

The borehole that is used to bury the grouting nozzle or press the grout to the grouting body after inserting the grouting pipe. The form of hole arrangement is related to the purpose of the injection of cluster slurry, the characteristics of the formation, the type of slurry, the sequence of injection of the paddle, the drilling accuracy, the form of the grouting pipe and the time of the slurry gel. The commonly used forms are single hole, double hole, single row, double row, plum flower shape, three-trouser rounded, square and hexagonal. The hole spacing varies with the fracture distribution and the permeability of the formation, and attention should be paid to prevent the occurrence of slurry and slurry when laying.

The depth of the hole depends on the depth of the grouting body, and the hole diameter should be small and not large, so as to reduce the amount of grout used for filling the borehole.

The porosity is the range of the porosity.

Porosity: The porosity is defined as the ratio of the total area of the sieve hole on the sieve plate to the area of the pore area (also known as the effective mass transfer area), that is, =a0 aa, where the porosity (%)

a0 - the total area of the sieve hole on the sieve plate (m2).

AA – Open Cell Zone (also known as Effective Mass Transfer Zone) Area (m2) Open Cell Zone: The area where sieve holes or mass transfer elements can be arranged.

For the opening and blocking porosity, its size is affected by the arrangement form of the sieve hole on the plate. The sieve arrangement of the plate tower has a regular triangular arrangement and an isosceles triangular arrangement. For different arrangement, the calculation of the hole center distance t is different.

For a regular triangle arrangement: t=d0(

Open porosity = a0 aa, which can be simplified as.

For an isosceles triangle arrangement, t=a0

n - the number of sieve holes.

The porosity of the effective mass transfer region is uniquely determined by the ratio of pore size to pore spacing.
