FIELD: electricity.
SUBSTANCE: group of inventions relates to structures of electric mains. System for near-surface laying underground cables or underground lines in the ground in the well along the laying route between the initial point and the end point includes a drilling machine, a heading head for driving a well, a drilling string and/or a casing string. Diameter of heading head exceeds diameter of casing string or drill string so that annular space is formed between well wall and casing string or drill string, which is equipped with lubricant. At that heading head is composed of drilling head system composed of drilling tool and drive of drilling tool to release soil while lubricant is constant lubrication. System is made with possibility of near-surface driving of well and with possibility of underground cabling, underground lines or protective pipe to which underground cables or underground lines can be introduced into the well, which is performed during or before removal from the well of drill string and/or casing string.
EFFECT: providing near-surface laying of underground cables or underground wires with pipeline section length up to 1,500 m.
