Description
Technical field
The present invention relates to constructing tunnel engineering fields, refer in particular to tube coupling structure and its construction party at a kind of combined type push pipe hole
Method.
Background technique
With the continuous expansion of city size, urban transportation is faced with increasingly heavier pressure.Subway is undoubtedly carrying capacity
Maximum, most quick, most convenient, most green transit trip mode, helps the significant stress for mitigating urban transportation.Therefore,
City underground engineering fully under way in domestic each big city.In subway engineering, the service channel between upper and lower line is usual
Construction is manually dug through using building method.And in research recently, have get in touch with using the mechanical equipment of push-bench etc and lead to
The formation of the construction technology in road.Such technique manually to dig through rear cast-in-place service channel outer wall originally, becomes by push pipe
The shell mechanism of tube coupling composition.Service channel and the node of subway uplink and downlink main line junction, which have, is similar to two sections of round tube phases
The special handover cambered surface handed over.If first, last tube coupling (also referred to as tube coupling at push pipe hole) also uses structure identical with general tube coupling,
The vehicle gauge that main line tunnel can be invaded hinders the normal operation of vehicle, need to be to first, last to guarantee that vehicle is normally run
On tube coupling invade vehicle gauge occupy-place part knock out, but do so destroy tube coupling and influence tube coupling structural integrity and its
Intensity, and then bring security risk；According to the different structure of general tube coupling, then will make the jacking block of push-bench can not be with
The non-universal first, last tube coupling comes into full contact with, and influences tube coupling assembling construction.
