Push pipe is worn old aviation oil pipeline protection architecture down

Technical Field

The application relates to the technical field of supporting structures, in particular to a protection structure for a top pipe to penetrate through an old aviation oil pipeline.

Background

In the construction of buildings such as airport expansion, the reconstruction of waterlogging drainage channels (drainage channels) and irrigation channels (irrigation channels) is often involved. In the reconstruction of drainage channels and irrigation channels, when the channel is close to the road or river channel in elevation and is intersected with a plane, an inverted siphon structure needs to be built, and a top pipe construction method is often used.

In the related art, the pipe-jacking construction method is to bury the pipe underground by pushing down the pipes made of reinforced concrete sequentially downward by the pipe-jacking equipment without digging the entire range of the buried pipe. When the pipe jacking construction method is used, the pipe jacking machine needs to penetrate through the lower part of an oil navigation pipeline so as to reduce the influence on oil supply of an airport. During construction, working wells need to be excavated at two ends of a construction area, and the pipeline is jacked into the stratum through the jacking pipe equipment to penetrate through the two working wells, so that the inverted siphon structure is constructed.
