Whether it is an old building or a newly built one, there are precedents of settlement and tilting. From the traditional forced landing correction (soil excavation correction) to pile driving and grouting, with the development of foundation reinforcement technology, the more advantageous Tongcheng Soft Foundation non-excavation settlement repair technology has emerged. What kind of house tilt correction and maintenance plan is this exactly? Let's take a look together.

The common causes of unevenness treatment in tank foundation

Weak geological influence: If the foundation soil itself is relatively weak, such as in a soft soil or silty soil area, or if the groundwater level is high, the effective stress of the foundation soil decreases, and the bearing capacity is greatly reduced, making it difficult to support the weight of the upper building, which will lead to the settlement and tilting of the building.

Design and construction issues: Unreasonable foundation design, such as too small foundation size and insufficient burial depth; During construction, operations were not strictly carried out in accordance with the norms, such as the quality of foundation construction not meeting the standards. Or if the geological conditions are complex and the soil properties within the same area vary greatly, it may cause uneven settlement of the foundation after being subjected to force, thereby triggering the tank foundation unevenness treatment problem.

External environmental influences such as rainfall and earthquakes: The intense crustal movement caused by earthquakes will subject the foundation soil to huge shear forces and vibration effects, resulting in structural damage and reduced bearing capacity of the foundation soil, thereby causing uneven settlement of the building foundation and resulting in tank foundation unevenness treatment. The flood erosion caused by rainfall will carry away the soil around the foundation, reduce the effective bearing area of the foundation, lower the bearing capacity, and eventually lead to tank foundation unevenness treatment.

Changes in the surrounding environment: Construction of adjacent buildings, such as deep foundation pit excavation and pile foundation construction, may alter the stress state of the surrounding foundation soil. The excavation of underground pipelines, long-term vibrations caused by transportation, etc., can also have adverse effects on the stability of the foundation, leading to tank foundation unevenness treatment.
