Modern gravity drilling rig technology – precise bores in any ground conditions
The development of trenchless technologies has enabled tremendous progress in building sewer, water and telecom networks without disturbing the ground surface. One of the most advanced solutions in this field is gravity drilling rig technology—a unique system that makes it possible to perform bores while maintaining an ideal gravity gradient, even in highly diversified geotechnical conditions.
Here’s how we avoided transport gridlock in Poznań? Our project on Grunwaldzka Street
Poznań – a city full of life and motion. Grunwaldzka Street in Junikowo is one of those routes that never sleep: four traffic lanes, a tram track in the middle, crowds of pedestrians.
When a new water service connection had to be built under this section, the challenge was clear. Open-cut? Impossible. Weeks of road closures, huge jams, trams replaced with replacement buses, closed sidewalks.

Lokalizacja i parametry odwiertu
Odwiert powstanie na terenie Zakładu Energetyki Cieplnej przy ul. Przemysłowej. Planowana głębokość to około 2 070 metrów, co pozwoli dotrzeć do zasobów wodonośnych o znaczącym potencjale energetycznym.
W samym sercu Gdyni, pod ruchliwą ulicą Morską, nasza ekipa MIDO wykonała ponad 40-metrowy przewiert grawitacyjny. Instalowana została rura o średnicy 180 mm, a cała operacja przebiegła bez zakłócania ruchu samochodowego i pieszego. Po dwa pasy w każdą stronę funkcjonowały bez zmian. Mieszkańcy i kierowcy nawet nie zauważyli, że pod ich stopami i kołami odbywała się precyzyjna operacja inżynieryjna.
The direction of the construction of the future is ecology
The construction of the future probably means modern, more sophisticated and fascinating forms, shapes and functionalities of objects.Further development of technologies and materials used in construction will be largely dictated by enabling the implementation of new construction investments, which at present, as a result of continuous technological deficiencies, remain only in the sphere of designers 'and contractors' dreams.The direction for modern construction and further development of construction technologies will also be the search for solutions enabling the reduction of costs, shortening of deadlines and reducing the nuisance to the environment during the implementation of new construction investments.
Rumia. Reconstruction of the existing water supply network and construction of new and reconstruction of the existing water supply connections. Excavation, with the need to dismantle the existing, new road infrastructure. Paused traffic. The construction site was accompanied by high emissions of harmful substances to the environment.
However, the factor determining the need for further development in the construction industry will be the improvement of the environmental performance of construction processes.The areas of searching for new technologies used in construction will be lower emission of pollutants and reducing the amount of construction waste.Lower emission of pollutants is also the path towards trenchless technologies.
Ecology is in trenchless technologies
It is well known that the construction of all underground installations with the use of trenchless technologies is definitely a more ecological form of their implementation, compared to traditional excavation methods.Implementation of installations with their use is a significant reduction of all negative factors accompanying the construction: costs, both direct and indirect, time, nuisance for the society.Trenchless technologies are the minimized activities and construction processes as well as the reduction of interference in the existing infrastructure, which directly translates into a reduction in the emission of harmful substances to the environment.
Construction of sewage connections to multi-family buildings in Olsztyn. Trenchless, without communication difficulties. Ecological.
Therefore, in order to make all construction processes more ecological, it is necessary to move towards increasing the role and application of trenchless technologies. They will have to marginalize the open trench technique. For this to happen, trenchless technologies should meet new expectations and requirements set for them by other construction industries. They will have to enable the implementation of underground installations, in an increasingly built-up and tight infrastructure, an ever denser network of underground installations, with minimal or even no interference with the existing infrastructure. In trenchless technologies, continuous development must be carried out to enable their application wherever their current form and current possibilities may prove ineffective. Therefore, the role of the development of trenchless technologies in the future is to ensure their greatest possible possibilities so that all construction works related to underground installations cause the least possible environmental pollution.
Modern trenchless technologies
An area where currently available and applied trenchless technologies are often ineffective is the construction of underground gravity sewage systems.The network of such installations consists of connections and collectors.The assembly of such installations is accompanied by a lot of difficulties and unusual features compared to other typical underground installations.First of all, gravity installations have to be placed with a defined, very precise slope, within a very tight tolerance range.Most often they are installed between two existing sewage wells, which are accompanied by dense existing buildings and road infrastructure, highly loaded with traffic.The places and depths of the foundation of gravity installations are usually accompanied by abundant and abundant underground groundwater. The aforementioned factors make it impossible to perform such installations using commonly known trenchless technologies. None of the commonly known methods, such as microtunnelling technology or screw drilling rigs, are able to provide the required parameters of the installation and the implementation itself in a completely trenchless manner. These machines require starting chambers, which involves the disassembly of the existing sewerage chambers. Therefore, in this area of underground installations, until recently it could be argued that either technology development will occur or they will still be implemented in a trenchless manner, inconsistent with the chosen direction of development, striving for the most ecological possible conduct of all construction investments. The construction market, modern, ecological, has determined the need for the emergence of new, modern, ecological trenchless technologies, replacing excavation technologies harmful to the environment.
Gravity drilling rigs
The area of trenchless technologies was not indifferent to the growing requirements and expectations of the construction market.In view of the growing needs and expectations of the construction market, this area responded with the development of opportunities in the form of developing a modern technology of gravity sewage installations using Gravity Drilling Rigs.This technology enables the installation to be made with very high precision, reaching 0.2%. Contrary to other commonly used trenchless technologies, such as the aforementioned auger drilling rigs or micro-tunneling machines, the Gravitational Drilling Rig enables the implementation of installations between existing sewage wells with typical diameters DN 1000, DN 1200 and DN 1500, from wells to wells, without the need to disassemble them andwithout the need for any interference with the existing road infrastructure.Modern Gravity Drilling Rig, the interior of an existing well is enough for the work area.
Construction of a sewage system at the Tricity Beltway with the use of a Gravitational Drill.
All works can be performed in any ground conditions and at any depth and in the presence of groundwater.New technology in the field of trenchless techniques has broadened the horizons of using these techniques. All installations of a similar type will be able to be implemented fully trenchlessly, i.e. ecologically, in accordance with the direction of development of the construction industry of the future. The use of excavation technologies in the case of demanding gravity sewage systems is a thing of the past.This is the role of trenchless technologies in the construction of the future. Make all underground work possible with their participation.Eliminate environmentally harmful, highly costly and burdensome excavation technologies. Using the example of modern gravity drilling technology, we can see that there is still a lot to be done in the field of trenchless technologies.One should only take due care to popularize these new technologies and possibilities.
