To solve the above-mentioned problems, the scheme that the utility model uses is: a kind of large aperture prestress anchoraging engineering pushes away
The tool for sending Anchor Agent, including the steel bushing for placing Anchor Agent, steel bushing one end open-ended, another end closure and the center point
Through hole is set, one section of connection short tube communicated with through hole, connection short tube and push steel are welded on the outside of steel bushing sealing end
The PVC casing connection of sleeve, the internal diameter of PVC casing, the internal diameter for connecting short tube are identical as through hole, form the perforation of a latus rectum
Pipe, the push reinforcing bar for pushing Anchor Agent are inserted into through tube by one end and protrude into steel bushing, and the top of reinforcing bar is pushed in steel bushing
End, which is fixed with one, can release the push gasket of Anchor Agent, and push reinforcing bar and push gasket form piston rod.
The connection short tube is threadedly coupled to together with PVC casing by stirrup.
The push gasket is discoid, the center point of the push reinforcement welding in push gasket.
The push reinforcing bar and push gasket are using welded connecting.
The steel bushing is the seamless steel pipe of outer diameter 68mm, internal diameter 65mm, length 400mm, connection stub length 50mm, interior
Diameter 20mm penetrates through bore dia 20mm, PVC casing length 9000mm, internal diameter 20mm, pushes reinforcing bar length 9400mm, diameter 12mm,
Push washer diameter 60mm, thickness 5mm.
The beneficial effects of the utility model are: can not only play the role of protecting Anchor Agent during pushing Anchor Agent,
It can also improve and send Anchor Agent efficiency and accuracy, ensure that the construction quality of prestress anchoraging engineering.
Detailed description of the invention
Fig. 1 is the tool vertical section schematic diagram that the utility model pushes Anchor Agent.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, the tool of the push Anchor Agent of the utility model, including the steel bushing 1 for placing Anchor Agent, steel
Through hole is arranged in 1 one end open-ended of sleeve, another end closure and the center point, welded on the outside of 1 sealing end of steel bushing one section with pass through
The connection short tube 6 that through-hole communicates, connection short tube 6 are connect with the PVC casing 4 for pushing steel bushing 1, the internal diameter of PVC casing 4, connection
The internal diameter of short tube 6 is identical as through hole, forms the through tube of a latus rectum, and the push reinforcing bar 2 for pushing Anchor Agent is inserted by one end
Enter through tube to protrude into steel bushing 1, the top that reinforcing bar 2 is pushed in steel bushing 1, which is fixed with one, can release the push pad of Anchor Agent
Piece 3, push reinforcing bar 2 and push gasket 3 form piston rod.
The connection short tube 6 is threadedly coupled to together with PVC casing 4 by stirrup 5.
The push gasket 3 be it is discoid, push reinforcing bar 2 be welded on push gasket 3 the center point.It is preferred that the push
Reinforcing bar 2 and push gasket 3 are using welded connecting.
Anchor Agent is placed in above-mentioned push Anchor Agent by a kind of Anchor Agent method for pushing of large aperture prestress anchoraging engineering
Tool steel bushing 1 in, by steel bushing 1 insertion applied in the bolthole being drilled, push PVC casing 4, tool is slowly even
In speed feeding hole, when pushing to bottom hole at the top of steel bushing 1, holds PVC casing 5 and extract outward, while reinforcing bar 2 will be pushed inwards
Push, entire pushing equipment is extracted after Anchor Agent is squeezed out Anchor Agent rest area by push gasket 3, is completed single group Anchor Agent and is pushed away
Circulation is sent, then this is moved in circles, completes the push of multiple groups Anchor Agent to make its close contact, it is ensured that reach design requirement.
For example, certain engineering prestressing force resin anchor design parameter is bolt diameter 28mm, long 9000mm, bolthole aperture
D76, hole depth 8800mm, selecting Anchor Agent diameter in conjunction with prestressed anchor design parameter is respectively 23mm, 28mm, length 350mm,
Single group is made of 3 diameter 28mm Anchor Agents and 1 diameter 23mm Anchor Agent.
According to the above parameter, the tool of production push Anchor Agent, steel bushing 1 is outer diameter 68mm, internal diameter 65mm, length
The seamless steel pipe of 400mm, connection 6 length 50mm of short tube, internal diameter 20mm, perforation bore dia 20mm, 4 length 9000mm of PVC casing,
Internal diameter 20mm pushes 2 length 9400mm of reinforcing bar, diameter 12mm, pushes 3 diameter 60mm of gasket, thickness 5mm.
By length 350mm, 3 diameter 28mm Anchor Agents and 1 diameter 23mm Anchor Agent adhesive tape bundle rear plug to placing anchor
Gu the steel bushing 1 of agent is delayed entire pushing tool by three people (each 1 people in both ends, 1 people of middle part) cooperation since pushing tool is longer
Slowly at the uniform velocity it is sent into that the bolthole aperture applied and be drilled is D76, length is in the hole 8800mm, middle part construction personnel holds PVC set
Pipe 4 pushes, and when pushing to bottom hole at the top of steel bushing 1, middle part construction personnel is by PVC casing 5 together with the steel bushing for placing Anchor Agent
Cylinder 1 is extracted outward, and the synchronous push reinforcing bar 2 of holding of tail portion construction personnel pushes it inwards, is squeezed Anchor Agent by pushing gasket 3
Entire pushing tool is completely drawn out by Anchor Agent rest area out, three construction personnel out of hole, is pushed away to complete single group Anchor Agent
Circulation is sent, then this is moved in circles, completes the push of multiple groups Anchor Agent to make its close contact, it is ensured that reach design requirement.
Embodiment described above is merely to illustrate the technical idea and feature of the utility model, and its object is to make ability
Technical staff in domain, cannot be only practical to limit with the present embodiment it will be appreciated that the content of the utility model and implement accordingly
Novel the scope of the patents, i.e., same changes or modifications made by the revealed spirit of all the utility model, it is practical new still to fall in this
In the scope of the patents of type.
