Gyropress Method

Contents

Social infrastructures, such as roads, rivers, bridges, and levees, protect our life and property,and provide comfortable and cultural life. However, it is required to re-evaluate many of them interms of "objective", "function" and "location" due to physical degrading by long time use, rapid
urbanisation and changes in public demand.
Despite such requirement, many of these social infrastructures are concrete constructions,which are very difficult to be dismantled, removed, or added additional functions. The major
factors are that they are constructed without plans of dismantling and removal, and that there
are many physical restrictions for such works because of congested building urbanization.
Gyropress Method resolves these problems by its new concepts of construction method andstructure design. This method enables to install tubular piles with cutting bits attached on piles
toe by rotary jack-in system without removing existing underground structures. The installedpiles form the both foundation structure and building structure. This method is developed basedon the "advantages of the press-in principle" which have over 30 year achievements, andenables to carry out structure regeneration works and reinforcement works with preserving the"Five Construction Principles".
Structures constructed by Gyropress Method can be dismantled and removed. It means, it ispossible to plan future functional improvements, restorations to original environment(restoration of nature), relocation, and recycling of construction materials at the design stage.

Gyropress Method

Overview of Gyropress Method
Realisation of pile penetration by the tubular piles with gyropress
coring bits and "Gyropress Force" generated from press-in & gyration.

Epoch-making Design Concept for Regeneration andReinforcement of Function without Removing Underground Structure.

In Gyropress Method, a newly developed press-in machine, so
called "GYRO PILER" is used. GYRO PILER has a rotary cutting
function without diminishing the superiorities of the Press-inMethod.
It installs tubular piles with cutting bits attached on pile toe byrotary jack-in system, and travels on top of piles which arecompletely installed（completed piles）.

Gyropress Method can carry out regeneration works and reinforcement works without removing undergroundstructures. GYRO PILER can directly install structural material which eventually forms both foundation part andstructural part with Gyropress Method, construction works can be carried out with less work processes and least
negative impact to surrounding environment including economic activities. In addition, the completed structure has
ideal level of quality.

Overcoming various groundconditions by selecting bitarrangements.

◇ Working Under Physical Restrictions（GRB System）
Because Press-in Method can provide piling condition with minimum working area, it is the best
to be selected for working under severe physical restrictions such as narrow locations andunderneath overhead obstructions. In addition, it does not require temporary working platforms.

◇ Environmentally-friendly Construction（Controlling Soil Displacement/Environmentally-friendly considerations）
Soil displacement can be minimised by leveraging rotary cutting mechanism with special bits on thepile toe. It makes the piling work more environmentally-friendly.
Furthermore biodegradable oil and grease are adopted to GYRO PILER. They are naturally degradedand do not damage ecologic system, if they are flown out into water or soil in any possibility.

Pile Diameter（Max D2500）◇ Adoption of Large-Diameter Piles allows Economical Constructions
GYRO PILER can be used for variety of pile diameter sizes, pile arrangements and thecombination of batter piles. It allows to select economically optimal structure design.

Construction works can be carried out with Environmentally-friendly considerations,lower cost and shorter work duration at any work conditions.

GRB System

GRB System for "Temporary Work Less" Construction
GRB System is the construction technology which performs all of piling works such as pile conveying, pile pitchingand press-in work on top of completed piles. With the press-in machine（GYRO PILER）
in the front, Power Unit as apower source, CLAMP CRANETM to pitch piles and PILE RUNNERTM to convey piles from work base perform on topof pile head as working orbit. All machines are self-supported by holding existing piles with less risk of overturning.
Temporary working platform or detour road is not required even at waterfront, narrow land, slope and low overhead
clearance condition since influence range of work is minimised to just the width of those machinery. GRB Systemenables to construct just wall structure which is its original purpose of construction without any temporary works.

Gyropress Method

Applications & Reference

Construction under Overhead Clearance Restriction

Batter Pile Press-in
GYRO PILER has a lateral tilting
function. It enables to installbatter piles and anchor piles. It
can construct high modulus
retaining walls.

Even beneath overhead
obstructions, construction work
can be carried out with thecompact GYRO PILER. This ispossible because press-inmachines grip a pile close to thehead of completed piles.
Especially in cases whereoverhead clearance is severely
limited, the specially designed
short model of GYRO PILER
should be selected.
