set of equipment for trenchless laying of flexible pipes with a diameter of 110 to 225 mm, the method of horizontal directional drilling (HDD) air percussion action, dry method - without the use of bentonite. The uniqueness of this model is the presence of air percussion impact hammers at work combines three effects: the pressure, rotation and percussion. The small dimensions allow the machine to work as a pit, and from the finished well with a diameter not less than 1,2 meters. Successful design, in which the center of pressure coincides with the axis of the frame eliminates warping machine at work. Twisting and spinning rods during drilling, is performed by a special mechanism to facilitate the work of the operator at one of the most challenging and most repetitive processes. UNB9 used as a mobile kit for teams already working on more powerful units, and for the start, start a new business trenchless laying of pipelines. Unlike analogue, UNB9 - a system of air percussion, works dry method - which does not include the use of drilling mud. This makes it possible to achieve high economic effect. Advantages UNB9 in this aspect is a much lower cost of equipment and consumables, compared with counterparts - lack of bentonite and water can be many times lower operating costs and the cost of work done. UNB9 complements the existing, more powerful and heavy machinery at the expense of smaller dimensions in the convenience and mobility.
