The utility model relates to the steel pipe joint F type interface that is applicable to the large-diameter steel pipe jacking construction.
Background technique
Still do not have steel push pipe curve jacking engineering example at present, conventional steel push pipe tube coupling adopts the mode of welding earlier, back jacking, and needs the steel pipe joint to adopt articulated manner to connect in the curve jack-in process.
The model utility content
The purpose of this utility model is to provide a kind of steel pipe joint F type interface that is applicable to large-diameter steel pipe curve jacking construction, to realize the needing articulated manner between the steel pipe joint to connect in the curve jack-in process.
For realizing the steel pipe joint F type interface that is applicable to large-diameter steel pipe curve jacking construction of described purpose, be characterized in, comprise the tube coupling bellmouth of first tube coupling and the tube coupling socket of second tube coupling, the tube coupling bellmouth has first external diameter less than the body external diameter of first tube coupling, the tube coupling socket has first internal diameter greater than the internal diameter of tube body of second tube coupling, the outer end inner wall of tube coupling bellmouth is provided with socket flange, the inner inwall of tube coupling socket is provided with the socket flange, the tube coupling bellmouth is inserted in the tube coupling socket, be provided with black box between the inwall of the outer wall of tube coupling bellmouth and tube coupling socket, accompany wooden dunnage between socket flange and the socket flange, socket flange is connected by bolt with the socket flange.
The described steel pipe joint F type interface that is applicable to large-diameter steel pipe curve jacking construction, its further characteristics are that the interior external diameter of the body of the body of first tube coupling and second tube coupling is identical.
The described steel pipe joint F type interface that is applicable to large-diameter steel pipe curve jacking construction, its further characteristics is, there is the shaft orientation reinforcing rib plate inboard of socket flange, and also there is the shaft orientation reinforcing rib plate inboard of socket flange.
The described steel pipe joint F type interface that is applicable to large-diameter steel pipe curve jacking construction, its further characteristics are that the inboard of socket flange also has circumferentially strengthens gusset.
