Kui Taishin SSP Method
The Kui Taishin Super Strengthening Pile Bents Method, which is called the SSP Method, is an anti-seismic reinforcement construction method performed by rolling up pressed-into-ground steel plates on pile bent piers. The steel plates are pressed into the ground around the pile and an underwater non-separable type non-shrinking mortar is injected between the steel plate and the existing pile to integrate them into one structure. By this method, anti-seismic performance is improved. This method has been studied and developed as a public and private sector joint study, 'Joint study of anti-seismic reinforcement method development of existing foundation structure,' by the Public Works Research Institute since 1999.
For this method, the Association of Pillar Reinforcement method of pushing a steel pipe into the ground has been established, improved, and promoted.

NETIS Registration No.: KT-000101-V (Term of publication was finished)
The SSP method was assigned the second grade of recommended technologies in 2009 by the Conference of New Technologies Utilization System of the Ministry of Land, Infrastructure, Transport and Tourism.
Scope of Application
- Diameter of Pile: Ø300 mm to 1500 mm
- Type of Pile: Steel pipe pile, prestressed concrete pile, and reinforced concrete pile. Note: A cast-in-place pile is to be considered.
Features
- This method has economic benefits because it does not require a large amount of temporary construction.
- This method has good workability in the narrow space under a bridge and is environmentally friendly, with low noise and vibration.
- This method can be applied safely while an existing bridge remains open to public traffic.
- This method can minimize the effects on waterways and rivers due to the small cross-sectional area of river restriction during and after construction.
