Applications/Examples of results
**[Settlement Correction Work]** There are two methods as follows: 1. **Underpinning Method** …The underpinning method involves using jacks to level a settled house back to its original position. The weight of the house is used as a reaction force to drive prefabricated piles, such as steel pipe piles, into the ground until they reach the supporting soil for restoration. 2. **Pressure Plate Method** …After the settlement of the building has stabilized, the foundation is excavated, and jacks are placed on a rubble pile made of blocks and steel plates to correct the building's tilt. This method does not require large tools or materials, resulting in fewer areas needing demolition and reduced repair costs. It can be performed with minimal vibration and dust, allowing residents to remain in the building during construction. **[Pile Extraction Work]** …In the extraction work of existing piles, depending on the type of pile, the first step is generally to cover the pile head with casing and drill to eliminate friction between the ground and the existing pile, a process known as "cutting the edge." After that, the extraction is carried out using a method suitable for the site conditions and soil type.
