METHOD FOR ROBOTIC DESTRUCTION OF POST-EARTHQUAKE COLLAPSED STRUCTURES Russian patent published in 2015 - IPC E02F3/96 

FIELD: medicine, life-saving equipment.

SUBSTANCE: refers to equipment for saving the people under collapsed structures. Concrete is destructed fast by section, extension, and cyclic actions. Mechanisms are equipped by powerful reciprocating cyclic hydraulic actuators for column concrete jacking, crushing and wedging and reinforcement stripping by reinforce cutters, e.g. friction disks. A bulldozer blade is equipped with steel durable horns and a pair of powerful hydraulic mountings. A jib-type crane has three telescopic levers mounted on the vehicle. One of the telescopic crane levers is provided with a riveting brace and a powerful pulsating jack actuating a steel hydraulic tooth, whereas the second one has a hydraulic claw. The bulldozer is driven to a collapsed structure. That is followed by anchoring the bulldozer; the longitudinal horn travel is actuated, and sliding along the ground bed pushes the horn by the pulsating jack underneath the collapsed column. Cyclic oil feed into the hydraulic mountings is actuated, and the collapsed column is lifted 1 or 2 metres higher. The lever with the hydraulic claw is led to the column; a shaft is gripped tightly; the collapsed column shaft concrete is crushed in the cyclic mode for the reinforcement stripping. As may be required, remote control enables leading the second lever to the column; the riveting brace is put on the column shaft; the hydraulic tooth is actuated to pulsate by remote control to crush the concrete. The third lever is led to the stripped reinforcement. One of the devices is used to cut the stripped reinforcement with securing the column shaft not to fall down with the hydraulic claw. The cycles are repeated with the second column end gripped by the collapsed structure; the separated piece of the structure is removed and taken away from the obstruction site to the dumping ground or onto the vehicle; then the cycles are repeated, and the obstruction site is cleared by removing all the collapsed structures.

EFFECT: structural improvement.
