Description
Technical field
The utility model belongs to bridge construction field, and in particular to a kind of vertical prestressing mud jacking pipeline docking facilities.
Background technology
At present, thee-direction prestressed system is generally used in cantilever continuous beam and continuous steel frame bridge construction middle girder structure,
Wherein vertical prestressing system generally uses vertical fining twisted steel material, the tradition in the construction of vertical prestressing system mud jacking
Single mud jacking mode from bottom to up is all used, mud jacking needs to construct into cartonning, and construction operation area is small, and madjack pipe is by abdomen
Plate chamfering stretch out, reinforcing bar, template and concrete construction it is pre-buried on this section go out box beam in pipe influence larger, often mud jacking operation
This section of built-in pipe of Shi Faxian is blocked, and influences normal mud jacking operation, and causes whole mud jacking process efficiency low, operation inconvenience, pressure
Real less effective.
The content of the invention
The utility model is in order to which the efficiency for solving to exist during bridge vertical prestressing mud jacking is low, operation inconvenient, consolidation effect
Poor the problems such as, and then there is provided a kind of vertical prestressing mud jacking pipeline docking facilities.
The utility model is adopted the following technical scheme that：
A kind of vertical prestressing mud jacking pipeline docking facilities, including two groups of vertical steel pipes be arrangeding in parallel, every group of vertical steel
Pipe includes coaxial top plate vertical steel pipe and bottom plate vertical steel pipe, the top end face of top plate vertical steel pipe, the bottom of bottom plate vertical steel pipe
End face is connected to anchor plate, and the top of a top plate vertical steel pipe is provided with pulp-inlet pipe obliquely, and another top plate is vertical
The top of steel pipe is provided with level, the small steel of contour transverse direction in opposite directions provided with grout outlet obliquely, the bottom section of two bottom plate vertical steel pipes
Pipe, two horizontal small steel pipes pass through sleeve pipe connection；Insertion is connected with the coaxial top plate vertical steel pipe and bottom plate vertical steel pipe
Fining twisted steel, periphery are socketed with bellows.
The bellows and anchor plate, bellows and pulp-inlet pipe, bellows and grout outlet, bellows and horizontal small steel pipe,
Laterally sealant tape has been seized in the junction of small steel pipe and connection sleeve pipe respectively.
The installation site of the pulp-inlet pipe and grout outlet is contour, towards on the contrary, tilting.
The utility model by welded on vertical prestressing bar anchor plate welded on vertical steel pipe, top plate vertical steel pipe into
The horizontal small steel pipe of welding on slurry pipe and grout outlet, bottom vertical steel pipe, vertical steel pipe the inside insertion fining twisted steel, vertical steel pipe
Outer surface cover bellows, adjacent two vertical prestressings connect bottom laterally small steel pipe by connection sleeve pipe, make two it is vertical pre-
Stress mud jacking pipeline turns into an entirety, and can operate while completing two vertical prestressing bar pressures according to mud-jacking technology
Slurry；Not only cost of manufacture is cheap for the utility model, technique simple and fast, it is easy to operate and also improve efficiency of construction, saving
Construction cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- pulp-inlet pipes, 2- grout outlets, 3- fining twisted steels, 4- bellowss, 5a- top plates vertical steel pipe, 5b- bottom plates
Vertical steel pipe, 6- laterally small steel pipe, 7- sleeve pipes, 8- anchor plates.
Embodiment
With reference to accompanying drawing, embodiment of the present utility model is described further；
Vertical prestressing mud jacking pipeline docking facilities as depicted, including pulp-inlet pipe 1, grout outlet 2, fining twisted steel 3,
Bellows 4, laterally vertical steel pipe 5, small steel pipe 6, connection sleeve pipe 7, anchor plate 8.The utility model passes through in vertical prestressing bar
Weld on vertical steel pipe 5, top plate vertical steel pipe 5 and welded on welding pulp-inlet pipe 1 and grout outlet 2, bottom vertical steel pipe 5 on anchor plate 8
Connect and fining twisted steel 3 is inserted inside laterally small steel pipe 6, vertical steel pipe 5, the outer surface cover bellows 4 of vertical steel pipe 5, adjacent two are erected
Bottom laterally small steel pipe 6 is connected by connection sleeve pipe 7 to prestressing force, makes two vertical prestressing mud jacking pipelines whole as one
Body, and can operate while completing two vertical prestressing bar mud jacking according to mud-jacking technology；Wherein described bellows 4 and anchor
Backing plate 8, bellows 4 and pulp-inlet pipe 1, bellows 4 and grout outlet 2, bellows 4 and the small steel pipe 6 of transverse direction, laterally small steel pipe 6 and company
Seized respectively with adhesive tape close in the junction of female connector pipe 7；Described connection sleeve pipe 7 is using the pvc pipe or steel for being more than laterally small steel pipe 6
Pipe makes；The small steel pipe 6 of described transverse direction is welded as full weld with vertical steel pipe 5, and it is firm to weld.
