3. beneficial effect
The utility model convenient construction, can improve filling speed and grouting quality, is carried out the compactness of controlled grouting by controlled grouting amount, effectively can avoid the waste of grouting material and ensure that field operation face is clean and tidy.
Particularly, grouting plug is for detachable, hollow and be provided with check device, ensures that grouting material is unidirectional and passes through, can ensure that slurry can not reflux, grouting ends and removable grouting equipment, raising grouting efficiency; Piston head can ensure that when being in the milk the gas in grout hole is discharged, and also can bounce back together along with slurry simultaneously, accurately can learn position by piston rod, thus learns the closely knit situation of grouting; Sealing baffle plate can ensure that between component, binding material or other foreign matters do not enter in sleeve.
Accompanying drawing illustrates:
Fig. 1 is the utility model sectional view
Fig. 2 is the sectional view that the utility model connects in component
Wherein: 1-grout hole tube connector, 2-slurry outlet tube connector, 3-is in the milk plug, and 4-pulp plug, 5-piston rod, 6-piston head, 7-blast gate, 8-seals baffle plate, 9-annulus.
Detailed description of the invention:
With reference to the accompanying drawings and the utility model is described in further detail in conjunction with the embodiments.
A kind of reinforcing bar grout sleeve closes external device, its composition comprises: grout hole tube connector 1, slurry outlet tube connector 2, grouting plug 3, pulp plug 4, piston rod 5, piston head 6, blast gate 7, sealing baffle plate 8, annulus 9, described grout hole tube connector 1, slurry outlet tube connector 2 are in the milk with sleeve, slurry-feeding hole is connected; Grouting plug 3 is connected with grouting tube connector 1; Pulp plug 4 is connected with pulp tube connector 2, and piston rod 5 is connected with piston head 6, and piston head 6 installs blast gate 7, and piston head 6 is placed in slurry outlet tube connector 2, and piston rod 5 is through pulp plug 4; Sealing baffle plate 8 is placed in reinforced bar sleeve end, and sealing baffle plate connects annulus 98 times.
