STEEL INSTALLATION FOR CORE DRILLING AND NEW ENVIRONMENTALLY FRIENDLY CONSTRUCTION METHOD, CAPABLE OF REPLACING TRENCH AND WELL SURVEY Russian patent published in 2019 - IPC E21B3/02 E21B15/04 E21B25/02 

FIELD: soil or rock drilling; mining.

SUBSTANCE: group of inventions relates to a steel installation for core drilling and to a construction method using same. Steel installation for core drilling comprises a base, the main mechanism, a drilling tool, a drill rod and a steel core sampling system. Main mechanism is installed on the base, the base is made with possibility of adjusting the angle of installation of the main mechanism, the drilling rod is installed on the main mechanism, and the main mechanism is made with possibility of application for rotation and supply of the drill rod. Front end of the drill rod is rigidly connected to the drilling tool; the rear end of the drill rod is connected to the steel system of core sampling; the axis of rotation of the drilling tool is collinear with the axis of rotation of the drill rod. Main mechanism comprises: automatic feeder box frame, which is installed on base; spindle head base, which is provided on automatic feeder box frame; feed cylinder, which is installed on box-type frame of automatic feeder box frame to actuate base of spindle head for free movement along length of box frame; and a spindle head, which is installed on the base of the spindle head and clamps the drill rod for rotation of the drill rod.

EFFECT: technical result consists in drilling of rocks horizontally or at a small angle with extraction of core for replacement of trench and well survey, which depends on excavation of soil on a large area.
