冻结管断裂原因及防破裂措施

With the consistent application of freezing method in mine construction and the depth of mine increasing continuously , the fracture problem of frozen pipe is becoming significant. In shaft sinking with freezing method, Saline leaking caused by the breaking of the partial frozen pipe ,which can cause chain reaction of breaking , decrease the strength of the frozen wall and threat the safety of shaft sinking , how to prevent frozen pipe from fracturing or how to take effective remedial measures to avoid a further widening of the accident after the breaking of the partial frozen pipe is becoming technical difficulties. Through the frozen pipe stress analysis, reach stress distribution and stress formula of frozen pipe , the same time through the analysis of fracture behavior of the frozen pipes during the pirod of freezing construction and drilling installation , and get the causes of frozen pipe burst fracture , Further,get measures to prevent frozen pipes fromfracture cause by a variety of reasons through induction and summarization, there has great guide Significance for engineering and site construction.
