A kind of corrugated steel pipe Combined concrete push pipe, it is made of inner wall, outer wall, concrete layer, circumferential flange, and inner wall is
Corrugated steel pipe, outer wall are spiral welded pipe or corrugated steel pipe, are concrete layer between inner and outer wall, both ends are circumferential flange, ring
It is welded to connect respectively with inner and outer wall both ends to the inner port edge of flange and neighboring, concrete layer and inner wall, outer wall, ring
It pours and is integrated to flange, there is corresponding connecting screw hole at the both ends of push pipe respectively.
Above-mentioned corrugated steel pipe Combined concrete push pipe, there is reinforcing bar and WELDING STUDS in the concrete layer, reinforcing bar be it is netted
Uniformly distributed in concrete layer, multiple WELDING STUDSs are connect with reinforcement welding, the lower end of WELDING STUDS respectively with the steel ripple of inner and outer wall
The connection of tube wall vertical welding.
The circumferential flange of above-mentioned corrugated steel pipe Combined concrete push pipe, the push pipe both ends is connected to the steel wave of inner wall
At the wave crest that line pipe outwardly protrudes, there is screw hole at wave crest, there is screw hole to be connected with screw hole at wave crest a group camber on circumferential flange
Connecting screw hole, two push pipes have corresponding connecting screw hole with respect to junction respectively, and connection bolt is arc-shaped, arc-shaped connection spiral shell
Two push pipes are connected by the arc connecting screw hole that bolt passes through two push pipe both ends.
The beneficial effects of the utility model are:
The inner wall of the utility model uses corrugated steel pipe, and outer wall uses spiral welded pipe or corrugated steel pipe, can bear larger
Circumferential pressure；It is reinforced concrete structure between inner and outer wall, biggish thrust can be born；WELDING STUDS is corrugated steel pipe
It is connected to become an entirety with concrete structure, it is stronger.
The utility model is scientific and reasonable for structure, has given full play to the respective advantage of corrugated steel pipe and reinforced concrete structure,
With good resistance to compression, tensile capacity, while it being able to bear biggish axial thrust, can be used as push pipe use, can also make
For tunnel or the tube wall of arch culvert.
