Oil tank, water tank and other large tank weight is large, if the foundation is not handled well, it is easy to appear uneven settlement, not only affect the use of the tank, but also there is a great safety risk. What about building settlement problems with tanks?

Here are some common solutions:

1. Strengthening the foundation: If the soil quality of the foundation is soft or the change of water content leads to the building settlement of the tank, the method of strengthening the foundation can be adopted. Concrete methods include traditional grouting reinforcement, pile foundation reinforcement and so on. Traditional grouting reinforcement is to improve the bearing capacity and stability of the foundation by injecting cement slurry or other strengthening materials into the foundation. Pile foundation reinforcement is to transfer the upper load to the deep stable soil layer by driving piles into the foundation.

2. Change the foundation support method: If the foundation support method is not reasonable, it may also lead to tank building settlement. In this case, the problem can be solved by changing the way the foundation is supported. For example, the base area of the foundation can be increased, or a more stable support structure can be adopted.

3. Control overload: If the tank building settlement is caused by overload, then the overload situation needs to be controlled. This includes reducing the amount of storage inside the tank or reinforcing the foundation to increase its carrying capacity.

4. Adjust the construction process: If the tank building settlement is caused by unreasonable construction process, then the construction process needs to be adjusted. For example, in the construction process, more attention should be paid to the problem of soil quality, and more reasonable construction technology should be adopted to ensure the stability of tank foundation.

5. Foundation settlement repair: If the tank is building settlement, the backfill soil is loose, the thickness is large, the tank itself is heavy, resulting in subsidence, the tank is inclined, and the upper pipe of the equipment is strained and dislocated, the trenchless micro-hole foundation settlement repair technology can be used, and the new special composite material can be injected into the depth of the formation to consolidate with the soil to form a new composite foundation. Improve soil strength and foundation bearing capacity, and lift the floor as soil pressure and density increase.

Tongcheng soft foundation non-excavation repair technology, the use of new materials, microhole injection, does not affect the production and life, fast consolidation of soft foundation soil to form a new structure, to achieve flexible lifting. The technology meets the requirements of load lifting and reinforcement of large equipment, and rapidly consolidates the soil to increase the bearing capacity, stability and long-term durability of the equipment foundation, thus ensuring the normal operation and safe use of the equipment. Especially for enterprises loading large storage tanks such as inflammable, explosive and dangerous chemicals, tank tilting building settlement will seriously endanger safety, and it is urgent to strengthen and lift the foundation.
