Trench less communication laying, trench less pipes laying, engineering nets laying.
The main specialization of LTD “IngeStroy” company - trench less communication laying, including all basic versions of given kind of building: Horizontal directed drilling till d 1 000 mm, micro tunnelling till d 1 400/1 700 mm, the steel casing pressing with a hydraulic lifting jack till d 1 400 mm.
In most cases trench less engineering nets laying was done in high complexity conditions and works responsibility. Some of objects:
Trench less pipes laying by the municipal water pipeline building d 315 mm in waterlogged area in Yaroslawl, four the extension 1 800 m with a wells assembling and putting into operation. The works were done during 3 month.
The engineering nets laying, namely, stand – sewerage system from PND pipes with a HDD method of diameter 250 mm four common length 2 km in Suzdal street in Iwanowo.
The steel casing pressing d 1 200 mm in a centre of Shelkowo four an extension 150 m in a ground of IV category with a following work pipe laying PE 80 d 500 mm and putting into operation.
Ducker passage in two lines through Zapadnaya Dwina river with a steel casing d 426 mm, each four the length 350 m. The work was done with a HDD method in hard loam with a boulder inclusion.
The tendencys of last years shows that for the municipal servises of citys-megapolises of different countrys, where they do the intense engineering nets laying, the trench less pipes laying becoms the main method of works. The growrh of ners quontity, the intensity of transport movement, the toughening of ecological request, the contractility of building terms, all this factors have leaded to that trench less communication laying have strongly wined her place in an among with traditional building methods. The growrh of citys, the expansion of packed building, the need of replacement of worned engineering nets have sharply raised discomfort loading on citys population. Therefore the care of population is perhaps one of important factors why the trench less communication laying begins so “popular”.

The have discovered her application in a laying of pipeline and cable lines beyond the limits of towns. To that has promoted the rapid development of communication technologies, and also intensive building of new main oil, gas and fuel pipeline. In most of cases the trench less communication laying in this objects have not alternative simply.
Another one factor why trench less pipes laying find more and more expansion is the gradual developing of project organizations of knowledges about new building technologies. Today is growing quite obviously that the trench less communication laying and cleaning of pipelines have not alternative for the solving a problem of reconstruction and pipeline laying with using of special equipment.
