SPOSÓB ZABEZPIECZENIA RUROCIĄGÓW PODZIEMNYCH PRZED UJEMNYMI SKUTKAMI SZKÓD GÓRNICZYCHMETHOD OF PROTECTING UNDERGROUND PIPELINES AGAINST THE NEGATIVE EFFECTS OF MINING DAMAGES
Przedmiotem wynalazku jest sposób zabezpieczenia podziemnych rurociągów przed ujemnymi skutkami szkód górniczych.The subject of the invention is a method of protecting underground pipelines against the negative effects of mining damage.
Znany sposób zabezpieczania rurociągów przed szkodami górniczymi polega na zakładaniu na rurociągi kompensatorów dławikowych w ustalonych odstępach wynikających z prognozy deformacji terenu.The known method of securing pipelines against mining damage consists in installing gland compensators on the pipelines at fixed intervals resulting from the forecast of terrain deformation.
Wadą zakładania kompensatorów jest brak ich odporności przed naprężeniami działającymi we wszystkich płaszczyznach.The disadvantage of installing expansion joints is their lack of resistance to stresses acting in all planes.
Sposób zabezpieczenia rurociągów przed ujemnymi skutkami szkód górniczych według wy na lazku polega na tym, że rurociągi ułożone w wykopie wraz ze złączkami obsypuje się materia łem ściśliw-ym o dużej porowatości korzystnie elporytem na całej jego długości, w tym również w miejscach łęczenia się jednego rurociągu z drugim. Jako materiał ściśliwy można również stosować żużle lub trociny. Obsypanie rurociągu materiałmm o dużej ściśiwwości uelastycznia rurociąg na szkody górnicze. Złączki rurociągu mają przez to mniejszą możliwość zerwania się, a rurociąg staje się bardziej odporny na występowanie tzw. progów.The method of protecting pipelines against the negative effects of mining damage, according to the invention, is based on the fact that the pipelines laid in the trench with couplings are sprinkled with compressible material of high porosity, preferably with an elpite along its entire length, including at the points where one pipeline connects. with the other. Slags or sawdust can also be used as compressible material. Backfilling the pipeline with highly compressible material makes the pipeline more flexible against mining damage. The pipe fittings therefore have less chance of breaking and the pipeline becomes more resistant to the so-called thresholds.
