In a new way: on Korabelov district, underground pipes of the water supply can be changed by a tassurous way
In one day, 235 meters of underground pipes will be replaced with a combined method.
In the Korabelniy district of Nikolaev (near the house on Kububelov Avenue, 20/3), repair work is underway to replace the underground pipeline performed by the VIK Technology LLC - the contracting organization of Nikolaevvodokanal. The correspondent tells about this from the scene korabelov.info.
Part of the pipes are changed, as before (in an open way) - for this, a trench was torn off. And the part is in a new way: with the help of a drilling installation, which is immersed underground and paves horizontally pipes there, so for this you do not need to make a large hole.
Most of the works have already been mechanized, and therefore they are performed very quickly. At this address, before the end of May 10, they promise to make three punctures and finish the work.
Employees also showed equipment for the preparation of bentonite rosostra (an employee for cooling the drilling tool of a drilling machine) used to static strengthening the well inside.
"The drilled hole in the ground is filled with a bentonite mixture in order not to collapse, it holds the well. And this favorable environment for the pipe, Bentonite is washed out of excess soil from the well"- explained the foreman of "ViK Technology" Anatoliy Goloblya.
“This object is considered emergency, so you need to replace the pipes even with an old existing water supply. In order not to disconnect consumers from water supply.
The length of the pipe replacement is 235 m, the diameter is 225 mm.
Ways to carry out work - testranschery (during drilling operations) and openly - soil development, pipe laying and backfill. After we make an inspection into the existing network of the water conduit, fill out our pipe with water - we test. After that - flushing the pipeline, and only then - switching the final consumer of water to a new network, ”said the foreman.
