[Construction Case] Restoration of Office Building Ground Subsidence Due to the Hanshin-Awaji Earthquake

[Construction Case] Restoration of Office Building Ground Subsidence Due to the Hanshin-Awaji Earthquake

Restoration of office building subsidence! We will introduce an example of a building with 6 floors above ground and 1 basement level.

In the Great Hanshin-Awaji Earthquake, localized loosening occurred in the foundation of office buildings due to liquefaction and intense vibrations over a wide area of the coastal region, and we restored the areas that had sunk. We entered the underground pit (900mm) from the opening on the first basement floor and drilled holes. Additionally, since the groundwater level is at GL-1.0m, we installed injection pipes while performing water stop injections for the pressurized water. Due to the irregular shape of the building, we measured the uplift both externally and internally to confirm any bulging, and we applied JOG to prevent distortion. 【Case Overview】 ■ Location: 2-chome, Sakaemachi, Chuo Ward, Kobe City ■ Building Name: Office Building ■ Structure and Scale: RC structure, 1 basement floor, 6 above-ground floors ■ Foundation Structure: Slab foundation ■ Total Restoration Weight: Approximately 3,500t *For more details, please refer to the PDF document or feel free to contact us.

What is sinking correction work?

What is sinking correction work?

By reinforcing buildings with a solid foundation, we can reduce earthquake damage!

"Settlement correction work" refers to the construction aimed at correcting the sinking and deformation of buildings caused by changes in the ground due to ground subsidence, landslides, volume compression of fill, and crustal movements due to earthquakes, in order to restore stability. Are there symptoms of sinking or deformation, such as "a ball rolling when placed on the floor" or "cracks in the building foundation"? Apple House can fix it. By correcting the building to a solid foundation, it is possible to reduce earthquake damage. We will jack up the tilt of the building to level it and restore a safe and comfortable living environment. [Features] ■ Reduces earthquake damage by correcting the building to a solid foundation. ■ Levels the tilt of the building by jacking it up, restoring a safe and comfortable living environment. *For more details, please refer to the PDF document or feel free to contact us.

Double Lock Method - Settlement Correction Work

Double Lock Method - Settlement Correction Work

All tilts and subsidence of structures and buildings will be corrected.

There are two main methods for settlement correction. 1. The method of raising from the foundation installed on the building's base. 2. The method of raising from beneath the building's foundation. The first method only has the effect of correcting settlement. It is not recommended due to the need for anchor cutting and foundation chipping. The second method allows for not only settlement correction but also continuous settlement suppression measures through support piles or ground improvement up to the ground support layer. Our company offers the following methods for raising from beneath the foundation as part of settlement correction work: - Steel pipe pile driving method (underpinning) - Double lock method (liquid injection method) - Pressure plate method - House lifting and raising method The steel pipe pile driving method and double lock method are techniques that can prevent future re-settlement. Additionally, all methods can be carried out while maintaining the living condition without having to move out. The construction cost of the double lock method is about half that of the steel pipe pile driving method.
