Abstract
The utility model relates to a return-type air-dischargeable grouting joint for anchor rods. A valve body 1 is provided with a grouting inlet 2, a main grouting mouth 3, a side grouting mouth 6 and an air-discharging mouth 8. A channel 4 is provided with a valve core 5, and the valve core is a tee with two work positions, wherein, one work position is communicated with the main grouting mouth 3, the air-discharging mouth is closed by the valve core at this time, the other work position is communicated with the side grouting mouth 6, a nick 9 on the valve core is communicated with the main grouting mouth and the air-discharging mouth at this time, the main grouting mouth is connected with a hollow pipeline of an anchor rod, and the side grouting mouth is communicated with a hole arranged in a stop-grouting plug of the anchor rod by a grouting pipe 7.
Description
The utility model is relevant with the hollow grouting anchor joint.
During existing hollow bolt slip casting, because stop grouting plug is blocked anchor hole, the residual air in the anchor hole can not be got rid of, and slip casting is not full, influences workmanship.
The purpose of this utility model provides a kind of tieback connector that anchor hole slip casting is full of.
The utility model is realized like this:
But the valve body 1 of the recoverable exhaust bolt grouting of the utility model joint has slip casting inlet 2, main grouting port 3, side grouting port 6 and exhaust opening 8, valve stamen 5 is housed on the passage 4, the valve stamen is threeway two stations, one station is connected main grouting port 3, this moment, the valve stamen was closed exhaust opening, and another station is connected side grouting port 6, and the breach on the valve stamen 9 is communicated with main grouting port and exhaust openings at this moment, main grouting port is connected with the anchor pole hollow pipeline, and the side grouting port is communicated with hole on the anchor pole stop grouting plug by Grouting Pipe 7.
The utility model valve stamen 5 is the garden cylindricality, and its upper end bar 10 passes valve gap 11 and is connected with handle 12, between its lower end and the bottom 13 spring 14 is arranged.
The utility model is simple in structure, and is easy to manufacture, easy to use.Operation is quick, and can pressurize is full of anchor hole slip casting, and anchor hole noresidue air improves workmanship.
Fig. 1 is the utility model structure chart.
Fig. 2 is another state diagram of Fig. 1.
Fig. 3 is the A-A view of Fig. 2.
Following is embodiment of the present utility model:
The main grouting port 3 of valve body 1 is connected with anchor pole 15, and an end of slip casting flexible pipe 7 is connected with side grouting port 6, and an end passes the hole of stop grouting plug 16.On the valve stamen 5 three-way pipeline is arranged, be cylindricality, have tapering to cooperate with valve body.Its upper end bar 10 passes valve gap 11 and is connected with handle 12, between lower end and the bottom 13 spring 14 is arranged.Jagged 9 can be communicated with main grouting port 3 and exhaust opening 8 on the spool.
When station as shown in Figure 1, slurries enter Grouting Pipe 7 from side grouting port 6 and enter anchor hole 17, and residual air in the anchor hole is extruded from anchor pole hollow, enter atmosphere by the exhaust opening on the valve body 8, and when exhaust opening had slurries to overflow, anchor hole was full of by slurries.
When needs pressurizeed slip casting to anchor hole, as shown in Figure 2, the valve stamen was closed side grouting port and exhaust opening, connects main grouting port, slurries can be under the state of slurry filling machine pressurization to anchor hole in slurries pressurization slip casting, desirable lower contact to the setting pressure.
