New construction on the piled block retaining wall

207mm

Save on costs, Keep safety

The model experiment ofpiles by Satou Lab.

Only part of boulder concrete at thebottom was demolished, after thatthe self-supporting retaining wall
was built using KD Pile.

No permission was given due to theload of building foundation against
the existing retaining wall.

KD pile development"The small diameter steel piles, that are used
for retaining walls or small constructions
including houses, require smaller bearing
capacity than the piles used for tall buildings.
However, such a bearing may become
unstable in the case of anchor reinforcement
on softer grounds or cohesive soil withmiddle viscosity.
The KD Pile Method will solve such aproblem by stabilizing the bearing capacitywith the circle anchor plates fixed on pileends.
Also, KD Pile Method uses an appropriate
construction management
by applying the preventing measures toavoid the troubles easily arisen on the small
diameter steel piles".

The constructor wants effective land use

Dangerous cliffs turns up to be the most appropriate retaining walls

KD Pile Method can:Reduce the construction period with no baseplate is required,Have high designability, being in agreement with the surroundings,
Construct sites without demolishing existing buildings,
Be safe and resistant to earthquakes even on soft grounds,
Increase the site area with vertical retaining walls and use the ground effectively,
Cut two thirds of earth movings and use of concretes / reinforcing steels compared toL-type Construction Method.

4Reference point of sitting posture δ/D2

The retaining wall may collapse andnot complied with the regulation.

KD Pile Method can make the construction
work possible from the N-Value 8 with its
own-developed technology.

Dr.Hideto SatouThe insurance covers the retaining
walls for ten years under PL Law.
This is the first time in Japan.

KD1Pile Method is covered by the insurance

The Kanuka Design is in charge of total design, including structural calculation and stability analysis.
Kanuka holds the patents for six construction methods. We have the insurance ready tocover the retaining walls after construction.
The warranty is issued for Relief and Safety. With such insurance applied, the method has
a merit to obtain consent from not only constructors but from the neighbors as well.
