What is the method of foundation subsidence reinforcement?

1. Replacement cushion method.

It is mainly suitable for the treatment of shallow weak foundation and uneven foundation, and its main function is to improve the bearing capacity of the foundation, reduce the amount of settlement, accelerate the drainage and consolidation of the weak soil layer, prevent frost heave and eliminate the expansion and contraction of expansive soil. Soft soil is excavated within a certain range below the foundation ground, and then backfilled with high strength, low compressibility, and no aggressive material.

2. Strong compaction method.

It is suitable for treating gravel soil, sandy soil, low saturation silt and cohesive soil, collapsible loess, miscellaneous fill soil and plain fill soil. The hammer of more than ten tons to hundreds of tons falls freely from a height of a few meters to dozens of meters, and the soil is dynamically rammed, so that the soil is forced to compaction and reduce its compressibility and improve its strength.

3. Strong compaction replacement method.

It is suitable for projects with low deformation control on the foundation such as high saturation silt and soft flow plastic cohesive soil. The soft soil is discharged by heavy hammer ramming, and the block stone, gravel, sand or other granular materials are backfilled into the ramming pit, and finally the block (gravel) pier is formed, and the block (gravel) pier and the rammed soil mixed with sand and gravel around it form a composite foundation.

Precautions for building foundation reinforcement.

1. Before reinforcing the foundation, the situation of the foundation should be checked, such as water quality, geology, etc., if the foundation is not checked before the foundation is reinforced, it may lead to the construction personnel to judge the foundation of the building site wrongly, and specify the wrong construction plan, which affects the reinforcement effect of the building foundation, and even causes a secondary impact on the building.

2. After the completion of the foundation survey work, it is necessary to do a good job of geological data, which is very helpful for the construction of foundation reinforcement. After that, according to the site characteristics and use requirements of the building, the depth of the borehole is determined to ensure that the bottom end of the hole is just on the bearing layer, so as to achieve a better reinforcement effect.

3. If the depth of the borehole is too shallow, it will affect the bearing capacity of the foundation, of course, in addition to determining the depth of the borehole, it is necessary to ensure that the number of boreholes is sufficient, although it will increase the construction cost, but it can effectively avoid the quality problems of the building, thereby causing safety accidents.

Whether it is to build a building, a hospital, a school or other building, before construction, the foundation needs to be done, the pile foundation must be laid, and the foundation must be firm. If the foundation is not firm, it is easy to have problems such as tilting and sinking, and there will be greater safety hazards. What are the methods of foundation subsidence reinforcement?

Enhance the overall stiffness coefficient of the building, which can be achieved by adding transverse walls, ring beams, or reducing the ratio of the building's length to height; Load gaps can be adjusted; You can change the shape of the house and simplify the layout as much as possible; You can tilt the foundation.

What are the reasons for the sinking of the foundation.

1. The elasticity of the foundation soil is small, and after laying the foundation, although the soil is not destroyed, there is a problem of settlement becoming larger.

2. Confined groundwater is exploited excessively, resulting in the problem of foundation subsidence.

3. There is a weak layer below the foundation soil, which has been destroyed due to the influence of additional stress on the ground, resulting in the problem of foundation subsidence.

4. The spacing between the two adjacent buildings is too small, and the diffusion angle of the foundation stress is not enough, which leads to the increase of additional stress between the adjacent buildings, thereby damaging the foundation soil and causing the problem of subsidence.

5. The design of the building itself is large, and the stress at the bottom exceeds the original bearing capacity of the foundation, which makes the foundation sink.

What is the harm of foundation sinking.

If the foundation is not done well and there is a phenomenon of sinking, then the building will tilt, crack, or even collapse in the future. Generally speaking, if the foundation sinking height is not large, it will not have much impact, and it is best to strengthen and repair it in time for safety leakage.

Hello, dear teasing banquet fight. The above is a detailed answer to the question of how to strengthen the foundation sinking, I hope I can help you Xiangyuan. <>

Open the mountain and grind the heart].

The foundation can be reinforced by pit static piles under the original foundation, and the foundation can be strengthened by pile foundation dragging.

1. Reinforcement of pit static piles under the original foundation.

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.

2. Strengthen the foundation by dragging the pile foundation.

Piles can be arranged along both sides of the foundation, and after the piles are poured and maintained, the ring beams of the foundation are held up by arranging lifting beams on the pile body.

Purpose of foundation treatment:

1. Increase the bearing capacity of the foundation.

Foundation treatment can increase the bearing capacity of the foundation through measures such as reinforcing the foundation and digging the deep foundation, so that it can withstand the load of the building, so as to achieve the purpose of matching the vertical difference to ensure the safety of the building. This is especially important for carrying important structures such as large buildings, bridges, dams, etc.

2. Ensure the stability of the foundation.

Foundation treatment can change the physical characteristics of the foundation through covering, such as increasing the compactness and strength of the foundation soil, improving the moisture status of the foundation soil, controlling the settlement of the foundation soil, etc., to enhance the stability of the foundation, prevent the collapse and sliding of the foundation, and avoid structural deformation and damage to the building.

3. Lead prolongs the life of buildings.

Foundation treatment can make the soil in the foundation form a good consolidation state, thereby reducing the compression and deformation of the foundation soil and achieving the long-term stability of the building. In addition, it can also extend the service life of the building by preventing the infiltration of groundwater, reducing the corrosion and dissolution of the foundation soil.

4. Protect the environment.

Foundation treatment can reduce pollution and damage to the environment through the use of environmentally friendly construction processes and materials. For example, in the process of digging deep foundations, smooth walls, settler barrels and other construction methods can be used to avoid affecting the surrounding environment.

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.

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.

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.
