As shown in fig. 1 to 3, a grouting sleeve comprises a sleeve body 1, wherein a grout outlet 11 and a grout outlet 12 which are inclined upwards relative to a horizontal plane are connected to a side wall of the sleeve body 1, an included angle between an axis of the grout outlet 11 and an axis of the sleeve body 1 is an acute angle, and an included angle between an axis of the grout outlet 12 and an axis of the sleeve body 1 is an acute angle.
As shown in fig. 1 to 3, the grout outlet 11 is connected to a grout outlet pipe 2 inclined upward relative to the horizontal plane, and the grout outlet 12 is connected to a grout outlet pipe 3 inclined upward relative to the horizontal plane.
As shown in fig. 1 to 3, when the axis of the sleeve body 1 is perpendicular to the horizontal plane, the axes of the grout outlet 11 and the grout inlet 12 are both inclined upward by 45 ° with respect to the horizontal plane, and the axes of the grout outlet 2 and the grout outlet 3 are both inclined upward by 30 ° to 45 ° with respect to the horizontal plane.
As shown in fig. 1 to 3, the sleeve body 1 is used for connecting the upper structure 4 and the lower structure 8, the steel bars 5 pass through the sleeve body 1, the edge sealing material 7 is used for blocking the grouting material 6, and the grouting material 6 is poured through the grouting guide pipe 3 and the grouting hole 12.
According to the grouting sleeve provided by the invention, grouting is carried out from the grouting guide pipe 3, and grouting material 6 flows through the sleeve and enters the grout outlet guide pipe 2, so that grouting work is completed. Because the grout outlet pipe 2 is communicated with the interior of the sleeve, the filling condition of the grout 6 in the grout outlet pipe 2 can be observed through eyes after the grout outlet pipe is finished, so that the internal compaction condition of the sleeve can be inferred. Due to the gravitational potential energy, if a cavity 9 is formed inside the sleeve, the grouting material 6 in the grout outlet pipe 2 flows back into the sleeve, so that the grouting material 6 in the grout outlet pipe 2 is lost. The upward inclination of the grout holes 12 and the grout pipes 3 helps to block the backflow of the grout 6. If all the internal parts of the slurry outlet guide pipes 2 are lost, the cavity 9 in the sleeve can be judged, the high-efficiency expanding agent can be injected to fill the internal parts of the sleeve, slurry filling is completed, and the cavity can be effectively filled by later expansion of the expanding agent.
Example two
As shown in fig. 4, on the basis of the first embodiment, the slurry outlet 11 and the slurry inlet 12 which are inclined upward are replaced by the slurry outlet 11 and the slurry inlet 12 which are horizontally arranged, that is, the axis of the slurry outlet 11 is perpendicular to the axis of the sleeve body 1, the axis of the slurry inlet 12 is perpendicular to the axis of the sleeve body 1, the slurry outlet conduit 2 which is inclined upward is connected with the slurry outlet 11 which is horizontally arranged, and the slurry outlet conduit 3 which is inclined upward is connected with the slurry inlet 12 which is horizontally arranged.
According to the grouting sleeve provided by the invention, grouting is carried out from the grouting guide pipe 3, and grouting material 6 flows through the sleeve and enters the grout outlet guide pipe 2, so that grouting work is completed. Because the grout outlet pipe 2 is communicated with the interior of the sleeve, the filling condition of the grout 6 in the grout outlet pipe 2 can be observed through eyes after the grout outlet pipe is finished, so that the internal compaction condition of the sleeve can be inferred. Due to the gravitational potential energy, if a cavity 9 is formed inside the sleeve, the grouting material 6 in the grout outlet pipe 2 flows back into the sleeve, so that the grouting material 6 in the grout outlet pipe 2 is lost. The upward inclination of the grout pipe 3 helps to block the backflow of the grout 6. If all the internal parts of the slurry outlet guide pipes 2 are lost, the cavity 9 in the sleeve can be judged, the high-efficiency expanding agent can be injected to fill the internal parts of the sleeve, slurry filling is completed, and the cavity can be effectively filled by later expansion of the expanding agent.
EXAMPLE III
The invention also provides a construction method of the grouting sleeve, which comprises the following steps:
s1, arranging the grout outlet 11, the grouting hole 12, the grout outlet conduit 2 and the grouting conduit 3 obliquely upwards relative to a horizontal plane, connecting the grout outlet conduit 2 with the grout outlet 11 of the grouting sleeve, and connecting the grouting conduit 3 with the grouting hole 12 of the grouting sleeve;
s2, grouting from the grouting guide pipe 3, and finishing grouting when the grouting material 6 flows out from the grout outlet guide pipe 2;
s3, standing for a set time t1, observing the fullness of the grouting material 6 from the grout outlet pipe 2, if the grouting material 6 in the grout outlet pipe 2 flows back to the inside of the grouting sleeve, indicating that a cavity 9 is formed in the grouting sleeve, and if the grouting material 6 in the grout outlet pipe 2 does not flow back to the inside of the grouting sleeve, indicating that the cavity 9 does not exist in the grouting sleeve.
Example four

EXAMPLE five
On the basis of the third embodiment, if the cavity 9 appears in the grouting sleeve, a filling agent is injected through the grouting guide pipe 3 to fill the cavity 9 in the grouting sleeve, and the filling agent is a high-efficiency expanding agent.
According to the grouting sleeve and the construction method thereof, the problem that the internal compactness is difficult to detect is effectively solved in a mode of combining the flat hole inclined guide pipe and the inclined hole inclined guide pipe.
The grouting sleeve and the construction method thereof provided by the invention have the following advantages:
1. the detection in the slurry outlet conduit 2 is clear and considerable, which is beneficial to making judgment.
2. The detection cost is lower, the efficiency is high, and the influence of the building form is small.
3. The upward inclination of the grout holes 12 and the grout pipes 3 helps to block the backflow of the grout 6.
