CONSTRUCTION OF A PASSAGE USING HORIZONTAL DRILLING

Horizontal drilling is used for pipelines of medium and large diameters. Drilling of wells is carried out by horizontal drilling rigs, which involve preliminary development of the soil with the device of wells in the soil of a larger diameter than the pipe being laid. This method is not recommended for use on weak (water-saturated and loose) soils in order to avoid subsidence of the road surface [1, 2].
The effectiveness of the use of screw installations depends on the correct choice of the design and operating parameters of the installations.
More productive and widespread are unified horizontal drilling auger installations (UGB or GB), which combine the processes of drilling, laying protective casing pipes with continuous removal of soil from the hole (Fig. 1).
