How to strengthen the foundation sinking, and what to do when the foundation sinks

pier-type foundation or pit static pile reinforcement under the original foundation; The foundation can also be strengthened by pile foundation dragging.

When the stiffness of the building superstructure and the foundation is relatively good, the bearing layer is relatively shallow, the groundwater level is relatively low, and the construction excavation will not cause additional subsidence and cracking to the original structure, the pier foundation or the pit static pile reinforcement can be done under the original foundation. Strengthen the foundation by dragging the pile foundation, we can set piles along both sides of the foundation, and after the pile is poured and maintained, the ring beam of the foundation is held up by setting up a lifting beam on the pile body. Then, the repair mortar is poured into the cracked part of the ground for filling and repairing, and the reinforcement mesh is placed at the repair place for reinforcement.

There are many ways to repair the foundation, and we should determine the repair plan of the foundation according to the actual situation. When we found that the foundation was sinking, we had to contact a qualified design team to determine the reinforcement method, and the construction should be carried out by a professional and qualified construction team.

Hello, how to say it. First of all, you should reinforce the cracks that have potential safety hazards caused by subsidence. If the crack occurs because the strength of the wall is not enough, you can use the steel mesh to apply to the wall, add the wall reinforcement to fix, and finally pour fine stone concrete or layer cement mortar to reinforce.

Hope it helps.

Pure hand lookout.

Ground subsidence is a common occurrence in most buildings. When a building is built on soft soil, under the action of vertical load, the moisture and air in the soil will be slowly removed, the voids between the soil particles will be reduced, and the soil will be consolidated and compressed. As a result, the building built on top of the earth will sink.

For the general building foundation subsidence is very small, and it is uniform, and will not affect the normal use of the building. However, if the foundation subsidence is relatively large, especially after serious uneven subsidence, it will affect the normal use of the building.

If the problem is not too serious, although there is uneven settlement, the family does not feel it, that is, no obvious structural problems are found, such as wall cracks, door and window squeezing, floor slab breakage, etc. Don't be careless, though. In the future, it is necessary to pay attention to the changes in the subsidence of the foundation, and if the subsidence is found to be aggravated in the short term, or the above-mentioned diseases occur, it should be evacuated in time and the relevant departments should be notified to deal with it.

If after observation, the sinking does not change again, and there is no occurrence of the above-mentioned diseases, it is like living in the leaning tower, safe and sound.

Hello! The continuous sinking of the foundation may not have a problem with the quality, the building with the construction, rising, the foundation will definitely sink, there is almost no non-sinking, in the construction process of the building, the construction unit has been observing the sinking of the building, as long as it sinks uniformly within the allowable range, there is no problem, it is afraid of uneven settlement, so that the foundation is not dealt with. It is recommended to find a local housing safety appraisal agency or quality supervision agency to identify it more assured.

Let them give advice on how to deal with it, take remedial measures, and as long as the measures are effective, there is no problem.

It's a really complicated issue. The use of wooden piles is ancient, but economical, more used in the south and less often in the north. There are three possibilities for this kind of sinking:

First, the pile tip of the wooden pile does not hit the bearing layer, causing the upper static pressure to sink after increasing, and then fall to the bearing layer of the foundation soil (this situation is that it will not continue to sink after sinking for a while);

Second, continuous sinking, that is, the continuous sinking of the wooden pile has no sign of termination, which shows that the bearing layer of the foundation soil is still some distance from the pile tip (as for how much, I can't know, it may be a destructive distance), third, the wooden pile fracture (the static load on the pile exceeds the range it can bear). Of these three cases, the first one is better, observe for a while, and if the sinking does not continue, forget it, just redecorate the floor or wall. The second and third cases are more troublesome, which requires the reinforcement of the foundation.

This requires a professional construction team and professional equipment. However, the premise of these treatment methods is that you must know how deep the bearing layer of the foundation soil is under the house and what is the ground endurance of the bearing layer, so that the foundation can be reinforced accurately and scientifically. This also needs to be carried out by a professional geological exploration team.

I don't know what the area of your house is, I believe it will not be too big (not more than 200 square meters), in this way, even the survey belt reinforcement is about 20 tens of thousands of can be done (I am estimating, it is nonsense), how is it stronger than pushing to rebuild.

After the foundation sinks, it is necessary to take appropriate methods to reinforce it in time. At present, there are two main methods to deal with foundation subsidence. One is the cement grouting reinforcement method, which requires the water glass slurry and cement to be mixed in a certain proportion and then injected into the soil, but this method can only inject the grout into a slightly larger gap.

Another reinforcement method is lime pile squeezing reinforcement, which is more widely used than the former, and can inject cement into small gaps. Finally, you can fill the surface with soil, which will be even better.

Methods of improvement of the foundation.

1. Replacement method: when the bearing layer under the building foundation is relatively weak and cannot meet the requirements of the superstructure load on the foundation, the soil replacement cushion is often used to deal with the weak foundation. That is, the soil layer within a certain range under the foundation is excavated, and then backfilled with sand, gravel or ash with high strength, and compacted to compact.

2. Preloading method: The preloading method is an effective treatment method for soft soil foundation. The essence of the method is that, before the construction of the building or structure, the equivalent load is applied or graded on the proposed site, so that the pore water in the soil is discharged, the pore volume becomes smaller, the soil is compacted, and the bearing capacity and stability of the foundation are improved.

The processing depth of the stack preloading method is generally about 10m, and the processing depth of the vacuum preloading method can reach about 15m.

3. Strong compaction method: The strong compaction method is a foundation reinforcement method pioneered by L. Menard in France in 1969, that is, dozens of tons of hammers are used to fall from a high place, repeatedly ram the ground, and carry out strong tamping of the foundation. Practice has proved that the bearing capacity of the foundation after tamping can be increased by 2 5 times, the compressibility can be reduced by 200 500, and the impact depth is more than 10m.

If the foundation of the house sinks, the house will crack from the first floor upwards, and the first floor will have the largest rip, and the further up the floor will be, the smaller the rip will be.

There are many reasons why the foundation of the house will sink, the first reason may be because the foundation was not reinforced when it was built, the second reason may be because the soil used in the foundation is relatively soft, and the third reason may be that the weight of the building is relatively heavy, exceeding the gravity of the foundation.

In fact, in order to save costs, many real estate developers now lay the foundation is not particularly deep, so after a long time, the foundation will sink, and the consequences of the foundation sinking are still relatively serious, which is easy to affect the quality of the house, so many people still pay more attention to this aspect.

When rural people build a house, they will spend a lot of time on the foundation, and the foundation will be deeper, in this case, the quality of the house will be better, and the foundation will not sink in the later stage.

Foundation subsidence is caused by insufficient bearing capacity of the foundation or changes in the physical properties of the foundation soil. The main methods of reinforcing the foundation sinking are as follows:1

Foundation reinforcement: increase the bearing capacity of the foundation by reinforcing the foundation. Commonly used methods include reinforcing the foundation soil, reinforcing the foundation foundation, erecting the foundation, etc.

2.Increase the foundation area: By expanding the foundation area, the weight of the building is dispersed and the bearing pressure of the foundation is reduced.

Commonly used methods include widening the foundation and increasing the depth of the foundation. 3.Use of foundation reinforcement materials:

Use foundation reinforcement materials, such as reinforced concrete, steel sheet piles, etc., to increase the bearing capacity of the foundation. 4.Ground reinforcement and foundation isolation:

By setting an isolation layer under the foundation, the deformation of the foundation soil is reduced, and the foundation subsidence is reduced from talking about fiber difference. Commonly used methods include setting up isolation plates, isolation pads, etc. 5.

Ground reinforcement and foundation reinforcement: through the combination of a variety of reinforcement methods, to achieve better reinforcement effect. Commonly used methods include foundation reinforcement and foundation reinforcement, foundation reinforcement and foundation isolation, etc.

It is necessary to select the appropriate reinforcement method according to the specific situation, and pay attention to the security issues in the reinforcement process. It is recommended to consult a professional engineer or construction team for reinforcement.

The foundation subsidence may be caused by soil liquefaction, heavy rain, etc., and different reinforcement methods need to be adopted for the foundation subsidence caused by different reasons. Here are a few common methods of subsidence reinforcement of foundations:

Heavy pressure reinforcement method: The heavy pressure reinforcement method is suitable for cases where the foundation subsidence is not too severe. The main principle of the method is to lift the sinking foundation upwards and lay heavy objects on the foundation so that the foundation bears more weight, thereby reducing the degree of sinking.

Driving pile foundation method: Driving pile foundation method is suitable for the situation that the foundation is under the foundation and the silver settlement is more serious. This method requires a certain number of piles to be driven into the sunken foundation so that the foundation is reinforced.

Pile foundation underpinning method: The pile foundation underpinning method is suitable for the situation that the foundation subsidence is caused by soil liquefaction and other reasons, and the subsidence range is relatively large. This method needs to lay a certain number of pile foundations around the sunken foundation, and then use a underpinning structure to underpin the sunken foundation upwards.

Stirring pile method: The stirring pile method is suitable for situations where the foundation subsidence is not too serious but needs to be reinforced. This method needs to drive a certain number of mixing piles into the sinking foundation, and strengthen the foundation through the friction of the pile and the binding force of the concrete.

It should be noted that each reinforcement method has its scope of application and advantages and disadvantages, and the specific reinforcement method needs to be determined according to the cause and degree of foundation subsidence. At the same time, the choice of reinforcement method also needs to be weighed according to the actual situation to ensure the reinforcement effect and security.

Hello, dear, I have helped you find the result; Ground subsidence is a common problem in buildings, and if not reinforced in time, it can pose a threat to the safety of the building. Here are some methods of foundation subsidence reinforcement:1

Foundation Reinforcement Piles: Piles are driven underneath the foundation to increase the bearing capacity of the foundation. 2.

Pile foundation reinforcement: dig a pit of a certain depth under the foundation, and then lay reinforced concrete in the pit to form a pile foundation Zen object. 3.

Foundation reinforcement grouting: Drilling holes under the foundation and then injecting cement slurry or other materials to fill the voids of the foundation and increase the bearing capacity of the foundation. 4.

Foundation reinforcement reinforcement plate: install a certain thickness reinforcement plate under the foundation to increase the bearing capacity of the foundation. 5.

Foundation reinforcement reinforcement belt: A reinforcement belt of a certain width is installed under the foundation to increase the bearing capacity of the foundation. The above are common foundation reinforcement methods, which should be selected according to factors such as foundation settlement, soil type, and building structure.

It is recommended to conduct a foundation inspection to determine the reinforcement plan before proceeding with the foundation reinforcement.
