In recent years, reports of tank foundation instability treatment have been frequent. Generally speaking, foundation subsidence is usually caused by factors such as poor geological conditions, inadequate survey and construction, or underground seepage. When the tank foundation instability treatment problem occurs, scientific treatment measures must be taken in a timely manner to avoid bringing unpredictable impacts. Then, what are the maintenance plans for tank foundation instability treatment? Why does everyone pay attention to trenchless settlement repair technology? Let's learn about it together.

I. Reasons for Foundation Settlement and Pain Points of Traditional Foundation Reinforcement and Maintenance

tank foundation instability treatment is usually caused by multiple factors. In terms of geological conditions, special soil types such as soft soil foundation, collapsible loess, silty soil, and expansive soil have limited inherent bearing capacity. Under the influence of building loads, changes in groundwater levels, etc., they are highly prone to settlement. Construction quality issues, such as substandard foundation treatment and unreasonable foundation design, can also pose a hidden danger of foundation settlement. In addition, external factors such as surrounding construction and long-term soil erosion may also cause foundation settlement.

Traditional methods for foundation subsidence maintenance, such as excavation and replacement, and foundation underpinning, have many drawbacks. Large-scale excavation will not only damage the roads, greenery and other facilities around the buildings, but also may affect the safety of adjacent buildings. The pollution such as noise and dust generated during the construction process causes great disturbance to the residents' lives. Moreover, the construction period is long, which seriously affects the normal use of the building. At the same time, the maintenance cost remains high, which deters many property owners.

Ii. Principles of Trenchless Settlement Repair Technology

Trenchless settlement repair technology breaks through the traditional thinking and adopts minimally invasive methods to reinforce the foundation. Through dedicated equipment, precise positioning and drilling are carried out in the foundation. The specially formulated composite slurry is injected into the foundation soil under high pressure. On the one hand, after the slurry solidifies, it can effectively increase the density of the soil and enhance the cohesion between soil particles. On the other hand, the maximum reinforcement depth of this composite material can reach 60 meters, and the solidification time is controllable in seconds. As the pressure increases, it can lift the sunken building and restore it to the range of national standards.

In addition, Tongcheng Technology has also integrated intelligent monitoring systems. During the construction process, real-time monitoring is carried out to ensure that the repair effect reaches the optimal level.

Third, trenchless settlement repair technology has significant advantages

(1) Highly efficient and minimally invasive, reducing environmental impact

Trenchless settlement repair technology does not require demolition. It only needs to perform small-scale drilling operations at key parts of the foundation, minimizing the impact on the surrounding environment of the building and residents' lives. The construction speed is fast. Compared with the traditional excavation method, the construction period can be shortened by more than 30%, enabling the house to quickly return to normal use, and the repair period does not affect the normal life and use of residents.

(2) Precise reinforcement to ensure the repair effect

Relying on advanced survey and positioning technologies, the subsidence areas and weak links of the foundation can be accurately determined, achieving precise reinforcement. The intelligent monitoring system provides real-time feedback on construction data, ensuring that parameters such as grout injection volume and grouting pressure are precisely controllable. This enables the foundation reinforcement effect to meet the design requirements, effectively solving the problem of foundation settlement and enhancing the safety of the building. With national technical patents, rich experience and a 20-year warranty.

(3) Economic and environmentally friendly, reducing the overall cost

Due to the reduction of a large number of additional costs such as excavation, backfilling and restoration, as well as the indirect cost savings brought about by the shortened construction period, the overall maintenance cost has been significantly reduced. Meanwhile, less waste is generated during the construction process, which is in line with the concept of green environmental protection and achieves a win-win situation of economic and environmental benefits.
