FIELD: construction.;SUBSTANCE: method of pipelines protection from emergency situations, caused by karst holes, at which reveal the pipeline, perform the bored piles on its both sides, stack the metal socket under the pipeline, the half pipe with diameter larger than the pipeline diameter is used as the metal socket, metal socket is connected with bored piles using steel rope, which bends around the pipe, and the ends of the rope are fixed at the piles heads, using the slack adjuster, regulating the rope tension, cover the pipeline with the ground, install the sensors at the rope ends before the slack adjusters. Bored piles are made in such a way, that the pile top end and the pile metal shell top end are above the earth's surface at the same level, and the bottom of the pile metal shell does not touch the ground surface level. In the pile top end in the concrete, enclosed with metal shell, perform the end recess and guide, install the sensors at the rope ends before guide, insert the slack adjuster into the end recess, thereby protecting the slack adjuster and the rope ends from the military and weather actions. The horizontally turned cover is fixed to the metal hinged shell, which covers the end recess with the adjuster, reinforcing the adjuster protection. The electric contacts are reinforced at the horizontally turned cover and on the metal shell, while at the normal position, when the slack adjuster examination is not possible, the horizontally turned cover rests on the metal shell, while rotating the horizontal cover the electrical contacts are closed, turning on the warning device through relay, which alarms on the slack adjuster unauthorized inspection, that allows you to take measures in time.;EFFECT: improved protection of slack adjusters and steel rope ends from the military and weather actions, providing alarms, while the slack adjuster and steel rope unauthorized inspection is taken place.;1 dwg
