We require pile construction in a narrow ground area. Is an applicable method available?
We are seeking a method that has functions featuring bearing piles and retaining walls. What do you propose?
The NS ECO-PILETM and Gyropress methodTM require only small workspaces for construction. These methods enable construction in narrow ground areas, such as areas next to existing structures. They are also applicable for construction sites with restricted overhead clearance, such as sites under elevated bridges and overhead lines.
QYesWe want to drive piles into hard ground. Is a good solution available?
The Gyropress methodTM, in which steel pipe piles with cutting bits installed at the tip of the steel pipes are rotationally pressed in, allows the piles to penetrate hard ground and obstacles (e.g., reinforced concrete), being appropriate for hard ground, as well.
The RS plusTM method, in which vibratory hammers equipped with high-pressure water jets are used, features excellent performance in excavating the ground, thus being appropriate for hard ground areas.
QYesIs a pile method available that is appropriate for soft ground?
The NS ECO-PILETM method, in which the bearing capacity at the tip of piles is large, is appropriate for soft ground where skin friction cannot be substantially expected.
Steel Pipe Sheet Pile Foundations involve a method in which steel pipe sheet piles are combined and installed in the shape of an enclosure so that behavior of the sheet piles is unified, from which high horizontal resistance and high vertical-bearing capacity are generated, applicable even for soft ground.
The TNXTM method, in which expanded foot protection sections constructed at the tip of piles are unified with steel pipes, provides high vertical-bearing capacity, being appropriate for soft ground.
The Slip Layer Pipe Piles (piles resistant to negative friction) ensures a reduction of negative friction in soft ground.
The Submerged Strut method was developed to satisfy needs for aseismic retrofitting or the deepening of existing quay walls. The method reduces the size of workspaces and the length of construction periods, which contributes to economical construction.
The Sat-in Pile Foundation, in which the pillars, etc., of superstructures are directly connected to the foundation piles and in which concrete footing can thus be omitted, can reduce costs and construction periods at actual sites.
The Jacket technology is used for marine structures in which steel pipe truss foundations are combined with superstructures made from steel. The method makes construction speedy thanks to prefabrication.
Mechanical Joints utilize a method that takes the place of on-site welding of steel pipe piles and steel pipe sheet piles. Simplified jointing work and construction management ensures joint quality, reduces construction periods and workloads, and makes all-weather construction possible.
Steel Pipe Sheet Pile Foundations utilize a method in which steel pipe sheet piles are combined and installed in the shape of an enclosure, which functions as a temporary cofferdam or retaining wall simultaneously with bearing piles.
The Combined Wall method, in which steel sheet piles and steel pipe sheet piles are combined, performs the function of a retaining wall and the bearing function of vertical force, thanks to steel pipe sheet piles.
Q
Yes
We want to drive piles into a deep bearing layer or ground areas without a distinct bearing layer. Can you suggest a good solution?
The Steel Pipe Pile and Steel Pipe Sheet Pile methods, which are easy to be joined by welding, are appropriate for ground areas with deeper support layers.
Gantetsu pileTM is a composite pile that feature low steel pipe deformability along with excellent soil cement frictional resistance. They can be designed as friction piles.
We are seeking a method appropriate for improving quay walls and aseismic retrofitting. What are your proposals?
We want to save labor at construction sites and to speed up construction. Can you suggest a good solution?
QYes The NS ECO-PILETM and Gyropress methodTM have realized construction without producing waste soil
by introducing the rotatory press-in method. The NS ECO-PILETM, Gyropress methodTM, TNXTM method, and Gantetsu pileTM are environmentally
friendly methods that enable low-noise and low-vibration construction.

Without supplementary construction methods, penetration through a hard intermediate layer and embedding in a hard bearing layer are possible, which can reduce construction costs and periods.
Bulbs constructed by cement milk injection at the pile tips can realize high bearing capacity. In addition, filling cement milk onto the sidewall of piles can realize stable horizontal resistance.
In the RS plus method, vibratory hammers equipped with high-pressure water jets are used. The method features excellent performance in excavating the ground and assists in driving piles securely into the bearing layer.

A steel pipe sheet pile foundation is constructed by combining and installing steel pipe sheet piles in an enclosure shape. This can also be used for temporary cofferdams.
Foundations possible to be used both for temporary cofferdams and for permanent foundations can reduce construction periods and costs.
A group of steel pipe sheet piles moves together, which can provide high horizontal resistance and vertical bearing capacity, along with reducing the occupied area at the same time.
Using the interlocks of high shear strength can further reduce the size of foundations. The foundation can also be used for aseismic retrofitting of bridges.

Steel pipe sheet pile foundations are more rigid than pile foundations. The size of foundations can be reduced, which in turn reduces earth removal by construction and construction period.
If the shape of foundations is determined depending on displacement, using interlocks with high shear capacity can reduce the size of planes.

Designing the steel pipe pile considering corrosion allowanceA method in which thickness equal to the allowable quantity of the corrosion in steel materials during the service life of structures as a corrosion margin.
Cladding concrete to prevent corrosionA method in which concrete or mortar is cladded around the surface of steel materials.
The following methods are available to prevent the corrosion of steel pipe piles
1
2
Coating the steel pipe piles to prevent corrosion Four types are available with regard to this method: by painting; using organic lining; using petrolatum lining; or using inorganic lining
Examples of heavy anticorrosion steel pipe piles and steel pipe sheet piles
Steel pipe piles and steel pipe sheet piles are covered with a urethane elastomer at the factory to provide for an anti-corrosive function that prevents harbor and marine structures from corroding. They have excellent anticorrosion properties and are
products of stable quality produced at the factory. They can be constructed in the same way as steel
materials without a coating, in principle.
Electrolytic protection methodTwo types are available with regard to this method: by externally supplying a protection power source to prevent corrosion (external power method) or by attaching alloy such as aluminum and magnesium to the steel material as a sacricial anode (galvanic anode method).It is necessary to select the most-optimum corrosion prevention method according to the design and site condition. For details, please contact us.

The ribbed pilesThe ribbed piles have spiral shape ribs. The ribs work efficiently for improving the bond strength between the pipe and concrete or the pipe and soil cements, so it can used for steel-concrete composite piles or as the core of soil cements.
There are two types of ribbed piles, pipe with inner ribs and pipe with outer ribs.The mechanical properties and chemical composition of the ribbed piles are based on JIS A5525.
