The steel bushing 3 is hollow structure, and the reinforcing bar 1 of supply and demand connection passes through;In the present embodiment, also in steel bushing 3
Groove is respectively set in both ends inner wall, for accommodating sealing ring 2, cooperates shown in Fig. 2, sealing ring 2 uses wedge structure, rubber material
Matter has the characteristics that the microdilatancy that absorbs water, and sealing ring 2 is located between 3 inner wall of reinforcing bar 1 and steel bushing, in grouting, slurry jacking,
Make to agree with closer, the effect of the end of sealing steel bushing 3 after realization injection slurry;The inner wall of the steel bushing 3 is additionally provided with anti-
Cut key 5, cooperate shown in Fig. 2, the middle position of shear key 5 from steel bushing 3 is arranged symmetrically to both ends, between adjacent shear key between
Away from preferably steel bushing internal diameter, shear key and steel bushing can be specifically made into integration, be conducive to reinforcing bar shearing resistance extraction in this way;It is described
Two end side surfaces of steel bushing 3 open up stock inlet 7 and grout outlet 6 respectively, by forming cement starch to 3 inside slip casting of steel bushing
The function of connection reinforcing bar is realized in the inducing decomposition of calculi 4.
As shown in figure 4, the slip casting connector includes two sections of inlet pipes 14, control valve 11 and grouter 12, wherein fill
Pulp grinder 12 connects one end of control valve 11 by one section of inlet pipe 14, and the other end of control valve 11 passes through another section of inlet pipe
Stock inlet 7 on 14 connection steel bushings 3, control valve 11 have the function of grout injection control;The inlet pipe 14 and stock inlet 7,
It is all made of threaded connection between control valve 11, grouter 12, has the characteristics that easy for installation, good leak tightness.Cement slurry is through infusing
It starches connector and injects steel bushing 3, after grouting quantity and pressure reach design requirement, close the control valve 11 of slip casting connector,
Realize screen slurry.
As shown in figure 3, the pulp controller is for connecting grout outlet 6, it can be achieved that the observation of slip casting plumpness and pressure stabilizing screen
The function of slurry specifically includes three sections of grout outlets 13, control valve 8, pressure gauge 9 and check valve 10, wherein control valve 8
One end connects the grout outlet 6 on steel bushing 3 by first segment grout outlet 13, and the other end of control valve 8 passes through second segment pulp
Pipe 13 connects one end of pressure gauge 9, and the other end of pressure gauge 9 connects check valve 10 by third section grout outlet 13;Work as injection
When slurry is flowed out from pulp controller, check valve 10 is closed, slurry pressure increases in steel bushing 3 at this time, and pressure gauge 9 is surveyed in real time
Amount, operator reads according to pressure gauge to be judged whether to reach design pressure, closing control valve 8 if reaching design pressure,
Realize screen slurry.The grout outlet 13 and grout outlet 6, pressure gauge 9, are all made of screw thread company between check valve 10 at control valve 8

The main function of meter is to read grouting pressure in steel bushing, should meet design 1.5 times of ranges of grouting pressure.
The working condition of steel bushing are as follows: cement slurry injects cavity by stock inlet 7, as grouting amount gradually increases, filling
Then gap between steel bushing 3 and reinforcing bar 1 is flowed out by grout outlet 6;Meanwhile cement slurry is when entering in steel bushing 3, steel
2 water swelling of wedge-shaped rubber sealing ring at 3 both ends of sleeve, sealed port.Institute's cementing slurry exists in steel bushing in the process
Closely knit molding under high pressure.
The working condition of slip casting connector are as follows: cement slurry is injected steel from stock inlet 7 through slip casting connector by grouter 12
In sleeve 3, after reaching design grouting pressure and grouting amount, closing control valve 11 forms screen pulpous state state.Shield when reaching design
After starching the time, slip casting connector is removed, pipeline clear water is cleaned and used again.
The working condition of pulp controller are as follows: institute's cementing slurry is by grout outlet 6 through pulp controller stream in steel bushing 3
Out, after observation outflow slurry plumpness reaches requirement, check valve 10 is closed, whole system is in pressurized state, by pressure gauge 9
Actual pressure value is read, after pressure reaches design grouting pressure, closing control valve 8 forms screen pulpous state state.When reaching screen slurry
Between after, remove pulp controller, pipeline clear water is cleaned and used again.
In summary, the present invention provides a kind of pressure grouting set suitable for the connection of prefabricated concrete structure joint reinforcing bar
Wound packages is set, and the reinforcing bar 1 that need to be connected can be inserted in steel bushing 3, installs slip casting connector, cement slurry in the stock inlet 7 of steel bushing 3
Body is successively injected in steel bushing 3 through inlet pipe 14, control valve 11, inlet pipe 14 by grouter 12;Gradually with injection slurry
It fills between steel bushing 3 and reinforcing bar 1, slurry can be flowed out from pulp controller, close check valve 10, stablize grouting pressure, screen
Closing control valve 8, pulp controller can remove reuse to slurry after a certain period of time.High-pressure slip-casting can make the cement in steel bushing
Slurry is more closely knit.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
