PEX tubing cutting

When the drilling head deviates from the design trajectory the operator stops the rotation of the drill rods and sets Skok drilling head in the right position. Then carry out punching drill rods, set the bevel drilling head in the right position in order to correct the direction of the construction of the pilot hole is completed its exit in a given design point.
3.1 Puncture through the installation of horizontal drilling

The essence of the method is the PEX tubing cutting or expansion of horizontal wells and tightening them pipes (diameter 400 mm) with the punches or plugging in a ground steel pipelines with a diameter 400-1400 mm by means of pneumatic percussive machines. Pneumopunches have streamlined cylindrical body, which posted drummer and air distribution mechanism. Drummer under the action of compressed air is cracking down on the body, moving it. The movement of the body can occur both in forward and in reverse (reverse) directions.

Direct-puncture method is the fact that the passage of punch comes with high speed and low compaction of soil in the surrounding area. This is especially important if you want to lay pipelines in the ground at a short distance from each other, close to the existing communications, or at a great distance to the surface, thus allowing not violate the structure of soil and not to provoke any deformation in the area of plotting numerous underground utilities. Fig. 3.1.1 shows a diagram of the implementation of a puncture through the installation of horizontal drilling.
