Trenchless pipe

Types of trenchless pipe

This type of work allows underground installation of communication without disturbing the soil cover, which is a positive thing.In addition, this method of pipe laying has still a lot of merits:

• spends significantly less money;
• speed of work above and in addition, at any time of the year;
• Road Safety and other communication systems, as well as the surrounding landscape;

And besides, does not spoil the aesthetic appearance of streets, yards, parks and roads, which account for a very long time to recover dug by bulldozers and somehow covered with ditches.

there are several methods of laying pipelines without digging trenches Today:

• land Punching;
• piercing manually;
• horizontal drilling;
• using the old pipes.

dignity of every process

question arises, and what a better way?In fact, everything will depend on the specific situations, soil conditions, weather conditions, as well as the used equipment, which will depend on the price of such services.Consider in more detail each method, you can make further conclusions easily.

The second life of old pipes.

This method requires the use of special equipment - hydraulic calibrator.Its function is to pushing the new pipe inside the old one.To this end, the pipeline is connected directly to the calibrator and are gradually moving inside the pipe, fills it himself.It is necessary to consider the following: the diameter of the new pipe must be greater than or equivalent to the diameter of the old, only in this case it will be cost-effective use of the calibrator.In all other cases it is sufficient to use a conventional winch, capable to cope with this task.

soil Punching.

This method is ideal for laying large diameter pipes (1,5 m -2) in porous and loose sandy soil by using hydraulic jacks.In practice, it looks like this:

• First digs deep well, which strengthens the walls of a well;
• At the bottom of the pit mounted hydraulic jack;
• its piston mounted horizontally;
• Next pneumatic striker pierced track laying pipe;
• This track is inserted directly to the pipe and secured with a piston;
• Then jack begins to move in the right direction with the fixed structure;
• Ground cork, formed inside, removed by mechanical means.

Do not use this technology, if the pipe diameter exceeds permissible dimensions, as even joined by welding, such designs are and continue to move in the right direction, and may at any time to change it.

Horizontal drilling.

This method of trenchless pipe laying involves the use of special rig and allows you to pipe installation, even in places where other methods would be powerless.The exceptions are areas blurred groundwater.

drilling technology is not very complex and is similar to the conventional horizontal drilling.High power of this equipment allows to reach speeds of horizontal drilling up to 20 m / h.The advantage of this method is the possibility to run for long distances with the diameter size of 1.5 m pipe.

Depending on the selected method, communication lengths, soil condition and other factors, will depend on the price of such services.
