Giken Seisakusho Asia Pte., Ltd. (“Giken Asia”, Head Office: Singapore, President: Yoshihisa Fujisaki), a group company of GIKEN LTD. (Head Office: Kochi-shi; President and CEO: Atsushi Ohira), has delivered the GYRO PILERTM GRV1230, a tubular pile rotary cutting press-in machine, to Guan Chuan Engineering Construction Pte Ltd (“Guan Chuan”). Guan Chuan is a Singapore-based company specialising in construction work and a technical partner. This is the first time that the GYRO PILERTM has been delivered to users in Southeast Asia.
Guan Chuan is the first company in Singapore to introduce a machine for hard ground and is a strong partner that has developed the market by disseminating the construction method on its own. Although the Gyropress MethodTM, a rotary cutting press-in method for tubular piles using the GYRO PILERTM, has been adopted in more than 1,000 cases in Japan and is steadily expanding overseas, it has not yet been proven in the country. Furthermore, since there were no actual machines on site, it was difficult to make proposals and it took time to create projects. With this delivery, it is expected that the adoption of the construction method will become more concrete.
More than 80 people involved in the construction participated in the demonstration held in Singapore. This has given momentum to the spread of the construction method upstream, where various projects such as redevelopment and storm surge and flood countermeasures can be planned that can utilise the advantages of the Gyropress MethodTM. Going forwards, the GIKEN Group will continue to work with the company to formulate projects using this method.
■The Potential of the Gyropress MethodTM in Singapore
Using the Gyropress MethodTM, tubular piles are pressed in while rotating with the assistance of cutting ring bits attached to the pile toe. This method enables the piles to penetrate existing structures and hard earth to quickly build a robust and resilient ImplantTM structure.
Since it allows for the penetration of existing structures, there is no need to remove remaining materials, and since the preliminary drilling work by an excavator, it reduces construction costs and lead time. It also makes it possible to conduct space-saving, temporary work free, vibration-free, and noise-free construction with a compact machine.
Accommodates the increase in projects on narrow land and hard ground
Singapore is a small country, and there are many cases where construction is necessary in places where facilities and people are densely crowded together. Singapore is also notable for an increase in the number of construction projects on hard ground in recent years. The Gyropress MethodTM is expected to be widely adopted in redevelopment projects at sites where existing facilities are crowded together, canal revetment repairs, and national resilience projects such as raising levees in preparation for rising sea levels.
■Demonstration held using the actual machine; proof of superiority to related parties
In November 2023, a demonstration was held in Singapore under the technical guidance of GIKEN Group company, GIKEN SEKO CO., LTD. (Head Office: Kochi-shi, President & CEO: Akihiro Nishigawa). The demonstration was attended by more than 80 people, including those from Singapore’s government agencies, construction consultants, and general contractors. Participants who witnessed the superiority of the Gyropress MethodTM asked specific questions about its adoption, and there was a lively exchange of opinions, making it a great opportunity to make it appeal to the spread of the construction method upstream.
■Profile of GIKEN Group
GIKEN developed SILENT PILERTM, the world’s first reaction-based hydraulic pile jacking machine, installing piles without noise or vibration. GIKEN Group now actively promotes its press-in technology worldwide and contributes to the construction industry by proposing and implementing innovative solutions. The innovative press-in technology provides a unique solution and the adoption of this technology has spread to over 40 nations and regions.
