Settlement correction work

basic information

Prior to construction, a detailed preliminary survey consisting of level measurements of the building's outer perimeter and indoor floors, an investigation of the subfloor, and 4 to 5 points of Swedish sounding tests will be conducted in one day, with the survey report, ground investigation report, and survey drawings submitted as deliverables. The steel pipe pile driving method can be executed while the building is still occupied (no need to move), with extremely low noise, vibration, and dust generation, and the space required for equipment storage is minimized. The process will be carried out under a consistent management standard, including preparation, demolition, excavation of the work area, driving and welding of the steel pipes using reaction forces, level adjustments with pile head jacks, filling mortar into the foundation base and head (root wrapping), and restoration of the subfloor concrete, among other tasks.

Applications/Examples of results

It is widely applicable for the recovery of structural integrity or maintenance of the current state when differential settlement occurs in structures. In practice, after measuring differential settlement, a monitoring period of six months is generally conducted, and the optimal construction method is selected based on the data trends. As examples, in cases where the soft layer is deep, methods such as steel pipe pile driving or moving the building and installing new piles are used, while in cases where the soft layer is shallow or after settlement has stabilized, a bearing plate method, which involves placing a pressure-resistant plate (steel plate) under the foundation, is applied. Additionally, when the goal is to maintain the current state after settlement has stabilized, a cement milk injection method is adopted, demonstrating a variety of applications based on the deformation patterns of the structure and ground conditions.
