Description
Technical field
The utility model relates to pour technical field of mold, and in particular to a kind of die assembly of big cross section tube coupling.
Background technique
Construction by pipeline jacking method is a kind of piping laying construction technology do not excavated or excavated less.Construction by pipeline jacking method is exactly in work
The top power generated in cheating by means of jacking device, overcomes the frictional force of pipeline and surrounding soil, by pipeline by the gradient of design
It heads into soil, and the earthwork is transported.The completion of one section pipe heads into soil layer and then lower second section pipe continues jacking.Its principle
It is that tool pipe or development machine are passed through soil layer always out of working pit by means of thrusts such as main top oil cylinder and pipeline enclosure, relay wells
It is advanced in reception hole and slings.After pipeline follows tool pipe or development machine closely, it is embedded between two holes.
Subway entrance pedestrian passage and street underground pedestrian passageway are approximate rectangular big cross section, using rectangular top tube method
When construction, the production of stress and big cross section tube coupling to tunnel proposes more, requirements at the higher level, therefore the construction of rectangular top tube method is only fitted
In Straight duct, still, subway entrance pedestrian passage and certain underground pedestrian passageway usually require to open in the side of duct
Hole, to meet the requirement of multiple exit, this does not meet the technical conditions of rectangular top tube method construction.
Utility model content
It can invent for appropriate design construction by pipeline jacking method and in big cross section tube coupling of the tube wall side opening to form multiple exit
People considers first to make more piece big cross section tube coupling form entirety by the method for anchor pole tensioning using push bench process, to be open in tube wall side
Afterwards, the weight of the big cross section tube coupling of opening is dispersed to whole big cross section tube coupling by anchor pole and is held by whole big cross section tube coupling
Weight.
