Doctor of engineering science, The "Kombest" Research-and-production
Joint Stock Company Director-General
The field of activity of the Research-and-production
Company "Kombest" is underground trenchless pipe laying and
rehabilitation of the underground utility systems. The relevance
of a trenchless technology development is obvious: less cost as
contrasted to conventional (trench) methods; ability of the pipe
insertion in conditions of high-density built-up, avoiding road
disruption, laying and rehabilitation of the pipelines buried at
great depths. The range of performed tasks is wide enough: development
and improvement of the process flowsheets, trenchless equipment
kits development and lot production. Besides, "Kombest" performs
planned in-house pipe laying and rehabilitation of the underground
utility systems. Corresponding trenchless technologies and equipment
kits are protected by Russian Federation and international patents.
State Joint Stock Company "Kombest" was established
in 1992 as affiliated undertaking of the Institute of Mining (Siberian
Branch of Russian Academy of Sciences). One of the shareholders
was large machinery complex - Omsk industrial association "Polyot".
The main task of the new-founded company was State innovative program
"New generation of technologies and equipment kits for underground
rehabilitation of the underground engineering services".
The program was developed by the Institute of
Mining - the leading Russian scientific institute in the field of
pneumopercussion machines. Long-term research-and-develop works
as well as implementation of fundamentally new high-performance
air-percussion machines of different purposes (pneumatic chippers
and jackhammers, downhole percussion hammers, pneumo-punchers, perforating
machines, hammer arrangement etc.) had become the base of this program.
Establishing of the powerful complex - Research
and development Institute & engineering plant (Institute of Mining
- Omsk industrial association "Polyot") as affiliated undertaking,
despite the very hard time of reforms, allowed in a comparative
short term develop and start the wide implementation of new progressive
trenchless technology of pipe laying and rehabilitation of the underground
Yet in 1993-1994 generally on a real objects of
reconstruction the extensive industrial testings has started. In
the middle of 1995 engineering plants began industrial models delivery
and in 1997 the commercial production of equipment kits has been
More than 12 kits of trenchless equipment have
been manufactured and passed to operation for last years. They run
in many Russian cities such as Moscow, St-Petersburg, Novosibirsk,
Omsk, Barnaul, Saratov, Irkutsk, Volgograd e.t.c. and were forwarded
to short-range oreign countries (Ukraine, Latvia).
Trenchless technology were used for replacement
of more than 130km of sewer pipes including such unique objects
as Moscow Kremlin, Moscow zoo, Novosibirsk Red avenue and other.
In 1998 according to new legislation State Joint
Stock Company was re-established to Joint Stock Company. The company
staff numbers more than 70 employees. The main part of research-and-development
department consists of Institute of Mining staff including one Doctor
of sciences and three candidates. Highly skilled engineers have
long-term work experience. Academical science combined with production
practice allows us to complete the most difficult objectives successfully.
