СПОСОБ ЗАЩИТЫ ТРУБОПРОВОДОВ ОТ АВАРИЙНЫХ СИТУАЦИЙ, ВЫЗВАННЫХ КАРСТОВЫМИ ПРОВАЛАМИ

摘要

FIELD: construction and pipeline operation, particularly to protect pipelines against emergency caused by doline. ^ SUBSTANCE: method involves exposing pipeline; forming bored piles from both pipeline sides; placing metal support under pipeline; connecting the support with bored piles and covering pipeline with ground. Bored piles are formed so that pile head is over ground surface. The metal support is half of pipe having diameter exceeding that of pipeline. Metal support is connected to bored piles by means of steel cable, which passes over pipe. Cable ends are connected to pile heads through tightening bushes for cable tightening regulation. Sensors are connected to cable ends in front of tightening bushes. ^ EFFECT: decreased labor inputs and metal consumption, improved visual control. ^ 1 dwg
