FIELD: drilling equipment for horizontal drilling, particularly for water, oil and gas manifold laying, sewage construction and electric and telephone cable running under water, rail and motor roads and conservation areas. ^ SUBSTANCE: drilling plant comprises frame and body hingedly connected with each other by the first end and fastened with each other along remainder length by row of length-adjustable jacks. The frame is secured to anchor driven in ground. Drilling string rotation device is installed on the body and is connected with spindle. One or several serially connected drilling pipes provided with drilling tool on free ends are attached to the spindle. The spindle also has reciprocating mechanism. Upper body surface has groove-shaped depression in which drilling pipe rotation means is installed so that longitudinal axis thereof, reciprocating mechanism axis and axis, which connects body and frame, are located in single plane. ^ EFFECT: increased service life due to bending moment elimination, improved operational safety due to prevention of load-bearing member whipping along with reduced material consumption, weight and costs. ^ 9 dwg |
