AI Technical Summary
During the grouting process, the polymer seeps outward through the gap between the grouting tube and the grouting hole, resulting in a poor grouting effect.
A grouting pipe device is designed, and a rubber ring, a screw sleeve and a locking device are successively penetrated on the grouting pipe. The rubber ring produces transverse deformation through the extrusion of the screw sleeve to prevent the slurry from oozing out. The locking device fixes the position of the screw sleeve through the tooth buckle and elastic rope to prevent the slurry from flowing out.
It effectively prevents the slurry from oozing, improves the grouting effect, and ensures the slurry sealing during grouting.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hole sealing equipment and relates to a grouting pipe device that prevents slurry from seeping out. Background Art
[0002] Since modern times, our country has made great achievements in highway construction. In terms of quantity, the total amount of highways in my country ranks first in the world. Most of my country's highways are semi-rigid base asphalt pavements. During long-term use, the semi-rigid base is affected by environmental factors such as dry-wet and freeze-thaw cycles, and problems such as hollowing will occur under the highway. With the rapid development of highway construction in my country, maintenance and repair will inevitably face severe challenges, and it is imperative to develop and promote non-destructive testing and disease diagnosis technology. A new concept of trenchless maintenance combining non-destructive testing and polymer grouting has been proposed, and a system technology for diagnosing and treating hidden diseases of highways has been developed, which has created a new way to treat difficult and stubborn diseases such as base hollowing and slurry overflow.
[0003] In the existing grouting technology, during grouting, when the polymer pressure under the road reaches a certain value, the polymer will seep out through the gap between the grouting pipe and the grouting hole, resulting in a poor grouting effect. Therefore, we propose a grouting pipe device that prevents slurry from seeping out to solve the above problem. Utility Model Content
[0004] The utility model aims to provide a grouting pipe device which can prevent slurry from seeping out, aiming at the problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical scheme: it is characterized in that the grouting pipe is sequentially provided with a rubber ring, a screw sleeve and a locking device, the upper end of the grouting pipe has a thread and a rack, the screw sleeve moves up and down through the thread, and the locking device is fixed in position by mechanical engagement with the rack.
[0006] Furthermore, the rubber ring is bonded to the screw sleeve and the grouting pipe at the top and bottom by adhesive. When the rubber ring is squeezed by the screw sleeve and the grouting pipe, the middle part protrudes outward, thereby achieving the effect of preventing seepage.
[0007] Furthermore, the locking device includes an upper clamping part, a lower clamping part, an elastic rope and a toothed buckle, and a hinge point. The upper clamping part and the lower clamping part are connected by the hinge point, and the elastic rope is looped over the outside of the upper clamping part and the lower clamping part so that the upper clamping part and the lower clamping part remain closed, and the toothed buckle is fixed to the head of the locking device.

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] The grouting pipe 1 is sequentially provided with a rubber ring 2, a screw sleeve 3 and a locking device 6. The upper end of the grouting pipe 1 is provided with a thread 4 and a rack 5. The screw sleeve 3 moves up and down through the thread 4, and the locking device 6 is fixed in position by mechanical engagement with the rack 5. The rubber ring 2 is bonded to the screw sleeve 3 and the grouting pipe 1 by adhesive. When the rubber ring 2 is squeezed by the screw sleeve 3 and the grouting pipe 1, the middle part protrudes outward, thereby achieving the effect of preventing the slurry from seeping out.
[0017] Working process:
[0018] After the grouting pipe 1 is inserted into the underground of the highway, the rubber ring 2 is squeezed and deformed laterally by rotating the screw sleeve 3 to prevent the slurry from overflowing. After the screw sleeve 3 is rotated to a suitable position, the tooth buckle 10 is opened by pressing the tail of the upper clamping part 7 and the lower clamping part 8 of the locking device 6. After the locking device 6 is moved to a position adjacent to the screw sleeve 3, the tail of the upper clamping part 7 and the lower clamping part 8 is loosened. Under the tightening action of the elastic rope 9, the tooth buckle 10 is closed. After the tooth buckle 10 is closed and mechanically engaged with the rack 5, the position of the screw sleeve 3 can be fixed to prevent the screw sleeve 3 from moving up during the grouting process and causing the slurry to flow out. After the grouting is completed, first press the tail of the locking device 6 to open the head tooth buckle 10, move the locking device 6 and the screw sleeve 3 up in turn, and the grouting pipe 1 can be taken out after the rubber ring 2 recovers its deformation.
[0019] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
