DP Foundation Construction Method

The existing concrete foundation method typically required road construction to bring in heavy machine to widely excavate the ground and a truck mixer to build the basic block. However, the DP foundation method method does not utilize any heavy machine nor excavates the ground and is workable even in weak ground (N conversion values of 0.5~2.0) where the existing method was impossible to construct.

DP Foundation Construction Method Features

Light weight to be transportable with manpower (17 kg in total and upper and lower parts are separable)
Need no heavy machine and constructible only with electric tools
No need for ground excavation and refill
Simple construction to shorten construction period
Very low impact on natural environment

DP Foundation Construction Method Overview

Easy way of construction even in weak ground while preserving natural environment
The foundation construction method is to install 4 pins in the ground to gain the bearing power to support a structure, targeting small-scale structures such as wooden road and observatory.

DP Foundation Construction Method Components

Cast-iron (ductile) GCD450 or over

※ Subject to change according to load

Pipe for zinc galvanizing
Rubber

DP Foundation Construction Method Application Conditions

Natural Condition
For cohesive soil, N conversion value of 1 or higher; for sandy soil, N conversion value of 3 or over
Field Condition

Field Condition
As DP method provides large supporting power, small horizontal strength and little directional nature,
it is suitable for structures with high pillar

Others
The upper limit of N value could be about 50KN (∮ 6.5 m/m), if only the type Pin size is adjusted.

DP Foundation Construction Method Application

Wetlands where installation is generally difficult with the traditional method
Steep hills where installation is generally difficult with the foundation method
Places with deep frozen ground
Inhabitants of precious animals and plants
Places where heavy machines cannot enter
Places where natural environment has to be preserved
Places having non-removable stagnant water

Farmland
Lake
Slope
Weak Ground
