Seal the seat pulp layer of the sleeve lower end；
S2, the sleeve is connect with upper component, and cleans grouting mouth, the grout outlet of the sleeve, the grouting of the sleeve
Mouth, grout outlet are mounted on valve；
S3, by high-pressure blast by the sleeve moisture and impurity blow out；
S4, evacuator is connect with the grout outlet, pressure grouting machine is connect with the grouting mouth；
S5, the valve for closing the grouting mouth, open the valve of the grout outlet, start the evacuator, make described take out very
Empty machine is sucked by vacuum the sleeve by the grout outlet, when the negative pressure in the sleeve reaches predetermined threshold, closes
The evacuator is closed, and the evacuator is removed and removes the grout outlet；
S6, the valve for opening the grouting mouth, start the pressure grouting machine, the pressure grouting machine are made to pass through the grouting mouth
Mud jacking is carried out to the sleeve, until having filled slurry, pressure maintaining certain time in the sleeve；
S7, the pressure grouting machine is closed.
As a further improvement of the present invention, the upper component, lower member are reinforcing bar.
As a further improvement of the present invention, the grouting mouth of the sleeve, be mounted on O-shaped rubber seal in grout outlet
Circle.
As a further improvement of the present invention, in step s 5, it when the negative pressure in the sleeve reaches -0.1MPa, closes
The vacuum machine.
As a further improvement of the present invention, the pressure grouting machine is piston type pneumatic mortar machine, the piston type pneumatic mortar machine
Without using compressed air pneumatic mortar machine.
As a further improvement of the present invention, in step s 6, when the pulp of the grout outlet and the grouting mouth enter
When slurry is consistent, then it is assumed that filled slurry in the sleeve.
As a further improvement of the present invention, in step s 6, the pressure 0.7MPa of the pressure grouting machine is kept, and is protected
Pressure one minute.
The beneficial effects of the present invention are: through the above scheme, on the one hand fundamentally having cut off grouting material by vacuumizing
The condition for forming air cavity, to ensure that Grouted density；On the other hand, negative pressure pressure maintaining certain time also makes up after grouting
Vacuum degree may deficiency lead to the air chamber generated.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of half grout sleeve grout construction method of the invention.
Specific embodiment
The invention will be further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of half grout sleeve grout construction method, comprising the following steps:
S1, will there is the sleeve 1 of grouting mouth, grout outlet to connect with lower rebar 2, seat slurry is carried out, in the lower end shape of the sleeve 1
At the seat pulp layer 4 for sealing 1 lower end of sleeve, elder generation's seat is starched when placing upper component, it can be ensured that 1 lower end leakproofness of sleeve is prevented
Spillage when only taking out slurry；
S2, the sleeve 1 is connect with upper reinforcement 3, and cleans grouting mouth, the grout outlet of the sleeve 1, the filling of the sleeve
Slurry mouth, grout outlet are mounted on valve 5,6, and the mounting O-shaped rubber seal 8 in the grouting mouth, grout outlet of the sleeve 1 is used
In seal sleeve 1 and building；
S3, by high-pressure blast by the sleeve 1 moisture and impurity blow out；
S4, evacuator 10 is connect with the grout outlet, pressure grouting machine 9 is connect with the grouting mouth, the pressure fills
Pulp grinder 9 can use piston type pneumatic mortar machine, and the piston type pneumatic mortar machine 9 does not use compressed air pneumatic mortar machine；
S5, the valve 5 for closing the grouting mouth, open the valve 6 of the grout outlet, start the evacuator 10, make described
Evacuator 10 is sucked by vacuum the sleeve 1 by the grout outlet, when the negative pressure in the sleeve 1 reaches-
0.1MPa closes the evacuator 10, and the evacuator 10 is removed and removes the grout outlet；
S6, the valve 5 for opening the grouting mouth, start the pressure grouting machine 9, the pressure grouting machine 9 are made to pass through the filling
It starches mouth and mud jacking is carried out to the sleeve 1, i.e., grouting material 7 is pressed into sleeve 1, until slurry has been filled in the sleeve 1, when described
The pulp of grout outlet and the entering when slurry is consistent for mouth of grouting (pour into that how many slurry go out that how many slurry illustrate in sleeve 1
Fill slurry), then it is assumed that slurry has been filled in the sleeve 1, has then kept the pressure 0.7MPa of the pressure grouting machine 9, and pressure maintaining
(or holding pressure) one minute；
S7, the pressure grouting machine 9 is closed.
On the one hand a kind of half grout sleeve grout construction method provided by the invention is fundamentally cut off by vacuumizing
The condition for forming air cavity, to ensure that Grouted density；On the other hand, negative pressure is held pressure and is also compensated for for one minute after grouting
The possible deficiency of vacuum degree leads to the air chamber generated.
A kind of half grout sleeve grout construction method provided by the invention is not free after taking out slurry processes using vacuum in sleeve 1
Gas forms cavity, and the good grouting material 7 of mobility will not form the cavity of vacuum, while the negative pressure after grouting holds pressure process meeting
The problem of making up the vacuum degree deficiency being likely to occur, grouting plumpness have dual guarantee.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
