The Causes And Prevention of Uneven Settlement of Foundations in Building Construction

In the field of construction, uneven settlement of the foundation is a significant threat to the safety and stability of buildings, and the application of rotary drilling RIGS is closely related to the condition of the foundation. Understanding its causes and mastering the prevention and control methods are of great significance for ensuring the quality of the project. The following is an analysis from multiple aspects.

1. Differences in geological conditions: Uneven distribution of soil in strata, such as the presence of weak soil layers and voids in some areas. Before the rotary drilling rig is put into operation, it is necessary to accurately locate the poor geological areas through geological investigation to provide a basis for the subsequent foundation treatment.

2. Groundwater impact: Changes in groundwater levels or poor drainage can alter the physical and mechanical properties of the foundation soil. During construction, rotary drilling RIGS are used to form holes and set up dewatering Wells to promptly lower the groundwater level and prevent the foundation soil from being soaked and softened by water.

3. Unreasonable foundation design: The mismatch between the type and size of the foundation and the upper load can easily lead to settlement problems. Based on the construction characteristics of rotary drilling RIGS, the depth and diameter of the pile foundation should be reasonably designed to enhance the bearing capacity of the foundation and balance the upper load.

4. Improper construction techniques: When drilling with a rotary drilling rig, if the drilling speed is too fast or the wall protection measures are inadequate, it may cause hole collapse and over-digging, affecting the stability of the foundation. It is necessary to standardize the operation process, control the drilling parameters and ensure the quality of hole formation.

5. Impact of adjacent buildings: The construction of new buildings causes disturbances to the foundations of existing buildings in the surrounding area. When using rotary drilling RIGS for construction, protective measures such as isolation piles should be taken to reduce the compression and impact on adjacent foundation soil.

6. Soil filling quality issues: Insufficient density of backfill soil and improper control of moisture content can lead to foundation settlement. When the construction of rotary drilling RIGS involves filling areas, the quality of the filling materials should be strictly controlled, and they should be compacted in layers to ensure the uniformity of the filling.

The causes of uneven settlement of the foundation are complex and diverse, and are related to multiple factors such as geology, design and construction. Rotary drilling RIGS, as important construction equipment, play a crucial role in all aspects of construction. Through scientific investigation, reasonable design, standardized construction and the adoption of targeted prevention and control measures, the risk of uneven settlement of the foundation can be effectively reduced, ensuring the safety and stability of construction projects.
