What to do if there is a hollow drum on the ground? How to deal with the hollow drum on the cement f

1.Phenomenon The ground hollow drum mostly occurs between the surface layer and the cushion layer, or between the cushion layer and the base layer, and there is a hollow drum sound when struck with a small hammer. After using it for a period of time, it is prone to cracking. In severe cases, large areas will peel off and destroy the function of ground use.

2.Cause analysis.

3.The surface of the cushion (or base layer) is not clean, and there are floating ash, slurry or other dirt. In particular, the white-plastered mortar in the interior is stained on the floor slab, which is not easy to clean up, which seriously affects the pad.

4.During the construction of the surface layer, the surface of the cushion (or base layer) is not watered wet or underwatered, and it is too dry.

There is a hollow drum on the ground, but what kind of ground does it have to see? Or what is the purpose of the ground? Under normal circumstances, if it is a living home, there is no big problem with the hollow ground, if it is a production requirement, then it may be necessary to cut the hollow drum and refill it.

You can open a hole in the hollow drum, and then pour in the cement mortar, when pouring with a rubber cone, you can use a rubber cone to vibrate, and after the cement mortar solidifies, then polish the surface to keep the surface flat. Of course, it is also possible to break the whole stone and pour cement mortar, but this method is more troublesome.

There are several ways to do this:

Dig a gap in the hollow drum and fill it with sand or cement when the gap is large enough.

Dig out all the mulch above the hollow drum, fill it with it, and redecorate it.

Hollow drums on the ground? Knock it out and break it, and do it again, otherwise it won't be long before the ground is broken and useless, knock it out and do it again!

For the edges and corners of the room, as well as the hollow drum area is not larger than and there are no cracks, it can not be repaired. The parts with frequent personnel activities, such as the door and middle of the room, as well as the hollow drum area is larger, or although the area is not large, but the cracks are significant, they should be renovated.

Partial renovation should be chiseled off the hollow drum part, the surrounding should be chiseled into a square or circle, and expand to the good joint 30 50mm, the edge should be chiseled into a slope shape, and the bottom surface should be properly chiseled. After chiseling, clean the repair area within 100 mm.

When repairing, first brush the plain cement slurry with water-cement ratio on the bottom surface and all around, and then fill it with a mixture of the same material as the surface layer; If the original surface layer is thick, it is advisable to fill it with mortar mixed with micro-expansion agent.

Causes of formation:

The plastering of the base layer of the wall is not disposed of as required or the garbage of the base layer is not cleaned up. Before tile paving, check whether the plastering of the wall base meets the requirements, and the wall base debris, dust and must be cleaned.

When paving, the back of the tile is covered with cement mixed mortar or 107 cement slurry and taps the tile with a hammer handle or soft hammer to make the cement grout crowd the back of the tile, and then press hard to make the tile firmly combined with the wall base.

Not soaked in water or not soaked enough before paving. Tiles (especially glazed tiles) should be soaked in water for more than 2 hours before paving, so that the tiles can fully absorb water, and then take out the shade to dry or wipe the clear water. If the brick is not saturated with water, it will absorb the water in the mortar prematurely, resulting in the mortar shrinkage and hollowing, and it will also affect the strength of the paste.

It is not easy to deal with the hollow drum on the ground, and it depends on the size of the hollow drum area. For the corners of the room or the hollow drum (no cracks) with an area of no more than 0 2 square meters, there is generally no need to repair it, because the location of these places will not be obvious and will not affect the appearance of the family. For the hollow drum with frequent personnel activities, it is necessary to deal with it immediately, so as not to affect other tiles for a long time.

When dealing with the hollow drum part chiseled off, cleaned up, watered and moistened one day in advance, repaired first on the bottom surface and around the brush with 107 glue cement slurry again, and then with the same cement mortar as the original ground according to the construction points for repair. If there is a large area of hollowing, the entire surface layer should be chiseled off and re-paved.

Ground hollows that are in the corners and hollow drums with an area of less than 400 square centimeters and no cracks generally do not need to be repaired. Local renovation should be hollow drum part chiseled away, around should be chiseled into a square or round, the edge of the chisel into a slope type, the bottom layer should be chiseled, chiseled, will be repaired around 100 mm within the range of clean, repair 1 day before the treatment, rinse with water, make it fully wet, repair first in the bottom surface and around the brush of water-cement ratio of the plain cement slurry again, and then fill with the mixture of the same material as the surface layer, such as the original surface layer is thicker, the treatment should be carried out in stages, each time the thickness should not be greater than 20mm. After the final setting, immediately use wet straw bags and other mulch to cure, and strictly prevent shrinkage cracks from occurring in the early stage.

For a large area of hollowing, the entire surface layer should be chiseled off and the bottom surface should be chiseled and re-laid.

How to deal with the hollow drum on the ground in the home improvement room?

For the treatment of ground stone hollowing, grouting repair treatment can be used. The position of the stone hollow drum is filled with resin, and the pouring is full to ensure the integrity and durability of the building and meet the requirements of normal use.

Prepare before construction to confirm the need for stone hollowing treatment. Drill holes, surface cleaning, and bury grout nozzles at the position of tile hollowing and drumming. Stone hollow drum treatment chemical grouting, grouting is implemented after the grouting nozzle is laid out, and the grouting pressure and grouting amount are determined according to the specific conditions of the stone hollow drum treatment part.

Engineer AB-5 grouting resin is poured into the grouting machine container after preparation.

The engineer AB-5 grouting resin is poured into the stone hollowing treatment position with a high-pressure grouting machine, and the valve is closed immediately after proving that the filling is full. When grouting, it is necessary to prevent the grouting liquid from overflowing from other holes, resulting in waste. Confirm that the grouting is complete and remove the implement.

After 48 hours, the resin was initially set; It can be used normally after 7 days of dry curing. Grouting quality inspection methods, percussion detection, coring testing.

The empty drum area shall not exceed 400C, and no more than 2 places per natural room (standard room) shall not be counted.

The ground hollow drum of the house is based on Article 5, 3, 4 of the Code for Quality Acceptance of Building Decoration and Decoration Engineering (GB50209 2002), "the surface layer and the next layer should be firmly combined, and there should be no hollowing and cracks".

With the naked eye**, the hollow drum part will generally be slightly higher than the overall plane around, and it is often accompanied by cracks, and it can be found that it is empty when pressed with your fingers.

Use a hollow drum hammer to slide on the plastered wall, listen to the sound, and determine the range of crisp or dull sounds that are different from other parts of the sound before the sound of the repentant sound.

The common way to repair the hollow drum is to shovel the sand ash, refill it with quick ash, and re-batch the putty after drying.

However, some hollow drums, due to the location and other reasons, it is difficult to chisel out, such as the hollow drum between the concrete protective layer and the base layer is more difficult, some more expensive stones, the hollow drum between the ceramic tile and the base layer, and the stone damage economic loss is greater after chiseling.

This type of hollowing can be solved by the method of perfusion repair. The AB resin grouting repair of some engineering crack treatment centers can inject high-strength adhesive into the hollow drum, and the empty position can be filled with full adhesion and compression resistance.

This kind of grouting repair hollow drum method is fast, does not damage the base, especially in the underground garage, plant and other sites, the construction process does not affect the use of the owner, is a more convenient way.

The hollowing of the ground is due to the fact that the bond between the ground and the floor is not strong, resulting in a clattering sound on the floor. I have some experience with the treatment, you can see if it is suitable, and the treatment methods include:

1.Re-flooring: If the floor is heavily hollow, it is best to re-surface the floor.

2.Find the location of the hollow drum: The bridge chain can find the location of the hollow drum by tapping the floor.

3.Glue injection: Inject professional glue into the hollow drum and press it with a weight until dry.

4.Nails or screws: If injecting glue doesn't work, you can use nails or screws to tightly connect the floor to the floor.

5.Strengthen the subfoundation: Before the floor is relaid, the subbase can be strengthened, such as by adding supporting wood strips or reinforcing the ground.

Hope it solves your problem.

Ground hollowing refers to the situation that after laying the ground material, after a period of use, the ground material and the ground foundation are loosened, resulting in instability. The problem of ground hollowing may lead to problems such as fracture of ground materials and surface falling off, which not only affects the aesthetics of the ground, but also may cause human health problems and increase the risk of life and property of users. Here are some ways to deal with ground hollowing.

1.Conduct on-site inspections.

When there is a hollow drum in the ground, it is necessary to conduct an on-site inspection to find out if there is damage or delamination in the pores and glues. After the inspection, ** reconcile the material and inspect the loose floor material. Large-area hollow drums need to be treated with surface damage.

2.Replace the flooring with new flooring.

When it comes to hollowing drums, a new floor covering is the most basic option, as the new floor material will be stronger and will be secured with a more durable glue during installation.

3.Inspect and patch voids.

After the inference of the ground material has been identified, the channel is checked for looseness, and the method is used to fill the gap or re-cover the ground material. When filling the gap, first of all, it is necessary to clean and remove the damaged part, appropriately adjust the new bentonite mixed with water and other materials to smooth the gap in the damaged place, and after drying, use sandpaper to trim the high-grade high-quality ordinary glue, and then cover the new ground pavement.

4.Grinding process.

For the problem of local loosening, mechanical grinding treatment can be used. Partial damage is repaired by grinding the surface and readjusting the loose areas. This method can be used to point out the damaged area, and the repaired area is not easy to produce hollowing in the future.

5.Apply a floor coating.

The use of epoxy primer at the same time as the coating color to increase the stability of the ground area can not only adjust the coloring, but also increase the durability and waterproofing effect of the ground. In the case of achieving the best application results, choose the most suitable colors and coatings to achieve the best results.

The above are some commonly used methods to deal with ground hollowing, you need to make a choice according to the actual situation and specific problems, it is best to find a professional ground maintenance company to deal with it. Due to the severity of the ground hollow drum situation, the treatment method will be different, if you are not familiar with the handling of the ground hollow drum, it is best to find a professional repair company to deal with it.

1.Introduction.

Ground hollowing is one of the common problems in the construction process of building materials, which can have a negative impact on the quality and service life of the building. This paper takes the ground hollow drum as the research object, ** the causes and treatment methods of the ground hollow drum, and puts forward corresponding suggestions.

2.Causes of hollowing on the ground.

The causes of ground hollowing mainly include the quality of raw materials, construction technology and use environment. First of all, the quality of raw materials is one of the main causes of ground hollowing. If the quality of raw materials is not up to standard, especially the quality of cement and mortar, it will lead to weak bonding between ground materials and prone to hollowing problems.

Secondly, the construction technology of Yamamori is also one of the causes of ground hollowing. The construction process is not standardized, such as failing to ensure the compactness of the ground material, failing to clean up the ground material in time, etc., will lead to the occurrence of ground hollowing. Finally, the use environment will also affect the occurrence of ground hollowing.

Environmental factors such as ground temperature, humidity and other factors will affect the shrinkage and expansion of ground materials, resulting in the appearance of ground hollowing.

3.How to deal with the ground hollow drum.

There are several main ways to deal with the ground hollow drum: first, use professional tools to clean the floor material, such as using a steel drill to open the ground material at the hollow drum, and then reapply the mortar. Second, use a professional restorative for repairs.

This method fills the gap in the hollow drum of the ground and makes it closely connected with the surrounding ground material. Finally, if the ground hollow drum seriously affects the use, you can consider replacing the floor material.

4.Suggestion.

In order to avoid the appearance of ground hollowing, it is suggested that attention should be paid to the selection of raw materials and quality control during the construction process, strengthen the management of construction technology, and improve the quality and efficiency of construction. The specific suggestions are as follows: First, choose the raw materials that are excellent for combustion, especially key materials such as cement and mortar.

Secondly, strengthen the management of construction technology, such as ensuring the compactness of ground materials and cleaning up ground materials in a timely manner. Finally, in terms of the use environment, such as ground temperature, humidity and other environmental factors, should be controlled to reduce the occurrence of ground hollowing.
