As an efficient foundation treatment method, the new tank foundation settlement improvement technology plays an important role in building correction. This paper will deeply discuss the principle and operation method of the new tank foundation settlement improvement and its remarkable effect in correcting the inclination of buildings, enhancing the bearing capacity of foundations and improving the stability of buildings. At the same time, the application cases of the new tank foundation settlement improvement technology in different geological conditions and building structures are analyzed to demonstrate its wide applicability and important value in the field of building correction.

As a self-developed and innovative foundation treatment method developed by Hengxiang Hongye, the new tank foundation settlement improvement technology -- non-destructive and controllable soil solidification technology has completely subverted the limitations of the traditional reinforcement method, which is time-consuming and inefficient, with its characteristics of rapid solidification and non-invasive and micro-interference. The technology uses a new type of special composite material, the use of 10-30mm minimally invasive technology, can quickly strengthen the foundation of high-rise buildings, 1-90s consolidation of soil, efficient completion of lifting and rectification. The construction of this technology is relatively simple, does not require large-scale excavation and reconstruction, does not need to stop production, does not affect daily life, and reduces the difficulty and cost of construction, especially suitable for complex geology, harsh construction environment, erratic construction or not easy to demolish changing building foundations, and foundation reinforcement has more advantages.

The new tank foundation settlement improvement plays a vital role in building correction, and its importance is mainly reflected in the following aspects:

I. The principle of new tank foundation settlement improvement

The new tank foundation settlement improvement is to inject special grout (Hengxiang Hongye Special new composite material) into the soil of the foundation, which penetrates into the pores and cracks of the soil under the action of pressure, and undergoes certain physical and chemical reactions (solidifying the soil). Thus, the strength and stability of soil mass can be improved.

Second, the role of new tank foundation settlement improvement in building correction

1. Correct the tilt of the building

When the building tilts due to insufficient bearing capacity of the foundation or uneven settlement of the foundation, the new tank foundation settlement improvement can correct the tilting state of the building by injecting slurry into the foundation on the tilting side, so that the foundation can be lifted and strengthened.

2, enhance the bearing capacity of the foundation

The new tank foundation settlement improvement can significantly improve the strength and stiffness of soil, thus enhancing the bearing capacity of the foundation. This is of great significance to prevent the building from sinking or tilting due to the insufficient bearing capacity of the foundation.

3. Improve building stability

Through the new tank foundation settlement improvement, the uniformity and continuity of foundation soil can be significantly improved, the uneven settlement and differential settlement of foundation can be reduced, and the overall stability of the building can be improved.

4. Improve soil properties

The mechanical properties of soil in different regions may be different. The new tank foundation settlement improvement can adjust the mechanical properties of soil by injecting special new composite slurry, improve the strength and bearing capacity of soil, and increase the cohesion and stability of soil. It can make the building foundation more evenly bear the load of the superstructure.

5, root correction, to prevent secondary settlement tilt

The new grouting can be strengthened around the corrected building foundation to form a continuous and stable reinforcement layer. This reinforced layer can effectively resist the influence of external factors, such as earthquake, wind loads, etc., to ensure that the building remains stable during long-term use. At the same time, the new tank foundation settlement improvement can also repair the cracks and damaged parts of the building foundation, improve the integrity and durability of the foundation, and further enhance the anti-tilt ability of the building.

Iii. Operation method of new tank foundation settlement improvement

The operation method of the new tank foundation settlement improvement usually includes the following steps:

1. Survey and design

A detailed survey of the foundation of the building is carried out to understand the geological conditions of the foundation, the property of the soil mass and the tilting state, and a new tank foundation settlement improvement scheme is designed according to the survey results.

2. Grouting drilling

According to the design scheme, holes are drilled in the foundation to be strengthened and grouting pipes are equipped. The grouting pipe should go deep into the soil layer to be strengthened, and ensure the sealing between the grouting pipe and the soil.

3, slurry preparation

According to the nature and reinforcement requirements of the soil foundation, the preparation of self-developed special new composite slurry, non-corrosive, rapid consolidation of the soil within 1-90s, diffusion radius can be controlled within 3m, safe and environmental protection. The slurry has good fluidity, permeability and curing properties.

4. Grouting construction

The grout is injected into the soil through the grouting pipe. The grouting pressure and grouting speed should be controlled during the grouting process to ensure that the grout can penetrate evenly into the pores and cracks of the soil.

5. Grouting effect detection

After the completion of grouting construction, the grouting effect should be tested. The testing contents include the bearing capacity of the foundation and the lifting and strengthening effect of the foundation.

Iv. Application cases of the new tank foundation settlement improvement

The application cases of the new tank foundation settlement improvement technology in different geological conditions and building structures are very rich. For example, in soft soil foundation, the new tank foundation settlement improvement can significantly improve the bearing capacity of the foundation and prevent the building from sinking or tilting due to insufficient bearing capacity of the foundation. In the sandy soil foundation, the new tank foundation settlement improvement can fill the pores of the sandy soil and improve the compactness and stability of the sandy soil. In the rock foundation, the new tank foundation settlement improvement can fill the cracks of the rock and improve the integrity and bearing capacity of the rock.
