1979
Iseki enjoyed the challenge of doing the impossible and defying experts who said it could not be done. Launch of the “remotely” operated Telemole revolutionzed Microtunneling.

1981
The Tele Crunchingmole (TCM) marked the next step forward, introducing a machine with an on-line “off-set” rotary crusher for processing cobbles and boulders.

1981
European branch established in the United Kingdom

1983
First “Pipe Roof” temporary works structure installed in Singapore, and to date Iseki have installed over 77km of microtunnelled Pipe Roof structures on 32 projects, possibly
marking Iseki as the world’s most experienced Pipe Roof Constructor.

1984
The radical Unclemole TCC (Tele Cone Crusher) with a unique epicyclical cone crusher (combined bi-deirectional and eccentric radial movement) came to the market.
A machine with a single cutter head that was capable of dealing with all soft ground conditions (Clays/ Silts/ Sands/ Gravels) along with boulders up to 30% of the machine size and soft rock. Soon to be recognized as the most versatile MTBM and with subsequent variants (TCZ, TCZ-M, Pipe-replacer, TCP & TCL) is probably the world’s most popular slurry MTBM.

1984
United States branch founded

1988
Mr. Kurose received Distinguished Honorary Professor Award from University of Alabama for his contribution to economic development between the United State and Japan.
Yoshihito Kurose Scholarship established for students majoring in international business

1994
Unclemole Super TCS range unveiled widening operational ground conditions to
include hard rock ≦200MPa unconfined compressive strength and boulders＞30% of the machine size whist maintaining the unique epicyclical crusher from the proven

Euro Iseki Overseas Thailand, JV company goes on to install over 81km of microtunnelled lines on 3 different projects

1995
Euro Iseki in the UK presented with the much coveted Queens Award for Export Achievement.

2000
Unclemole TCV inaugurated, system for direct trenchless installation of PCV pipe from 200mm ID to 500mm ID

2005
TCTS Shuttlemole introduced, customized Unclemole Super with retractable peripheral cutters facilitating MTBM recover through the installed casing pipe.
Specifically developed for the construction of blind-hole pipe roof structures.

2007
New Unclemole Super TCS which has a built in facility for man access to the cutter head through the machine, this allows cutting discs to be changed where long drives are undertaken.

2010
The largest diameter(4310mmO.D) TCS built for the pipe jacking project of
sixty (60) meter deep drainage in Saudi Arabia.

2012
Iseki Microtunnelling in the UK complete the UK’s most technically challenging
project to date

・980 metre 1.8 metre diameter long sea outfall.

・40 metre depth drive shaft

・300 metres installed on a 1 in 10 declined drive entering into an
Inspection shaft on a 600 metre vertical radius curve

・680 metres advanced under the English Channel on a 1 in 100 declined drive.

・Underwater seabed MTBM recovery

Plan of project

Section of project

・System deployed with Fiber Optic data transfer / control cables, first time use on a
microtunnelling System.

2013
Iseki Microtunnelling in the UK develop and produce the first “Bolt On” mixed face cutter head for the Unclemole TCC machine. Extending the operational range to include medium strength rock

Unclemole TCC cutter head ,Unclemole TCC-R Cutter head

2015
Iseki have installed over 77,764km of microtunnelled Pipe Roof structure on
32 projects as of today.

The main benefits of the Iseki Pipe Roofing Method are:

★Total security against settlement and ground movement.

★Cost saving over alternative methods.

★Flexibility of design.

Installed pipes are linked together to make secure structure , which is then supported excavated , and finally lined to create the finished tunnel.

2016

ISEKI TCTS Shuttlemole won an award at the China No-dig conference in Beijing

2017

ISEKI now offer you “Segmental Slurry Tunnell Boringmachine made in Japan and a back up equipment made in Korea.

2017

ISEKI develop and produce “New TCS” machine can be used to standard soil, mixed soil, and rock. Iseki offers the appropriate solution for all geological challenges.

Closing

Iseki has pioneered the introduction and partnership of Microtunnelling Equipment for over four decades, also with approaching 2,500 units produced they are probably the world’s most popular slurry MTBM

Iseki work in close partnership with Clients and Suppliers provide engineered solutions for infrastructure installations utilising Microtunnelling Technology.

As a manufacture and operator of rental equipment Iseki have gained a detailed appreciation of the capabilities of their Microtunnelling Systems and draw on this experience to assist Clients in delivering successful projects.
