Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grouting devices, in particular to a trenchless polymer grouting device. Background Art
[0002] Polymer grouting is a new building repair technology that is widely used in building maintenance and repair. Polymer grouting is the process of injecting polymer materials into the building structure through a grouting machine, similar to replenishing the building's "blood".
[0003] The purpose of polymer grouting is to strengthen the structure of buildings and fill cracks or damage in concrete, thereby enhancing the building's stability, load-bearing capacity, and earthquake resistance, extending its service life. It is widely used in the repair and reinforcement of civil and industrial buildings, bridges, dams, basements, and other structures.
[0004] Publication No. CN 219752950 U discloses a road repair grouting device. The utility model facilitates the cleaning of the grout bucket, reduces the failure rate of the machine, and has a handheld grouting device and a machine grouting pipe, with diversified operation modes and reduced material loss.
[0005] The above-mentioned prior art needs to perform a drilling operation first when performing grouting repair, and then the grouting pipe is inserted into the drilled hole with the hand-held grouting device. The grouting pipe of the existing hand-held grouting device is usually short, so the operator needs to bend over and squat to perform grouting. Excessive pressure during grouting will give the grouting pipe a reaction force, so the operator needs to press the hand-held grouting device hard, and the operator bends over or squats for a long time to work, with limited force, which is very physically demanding. The reason why the grouting pipe of the existing hand-held grouting device is usually short is that if the grouting pipe of the hand-held grouting device is long, then when the grouting pipe is taken out from one grouting hole and grouting is performed in another grouting hole, the remaining polymer slurry in the grouting pipe will flow out of the grouting pipe, which needs to be cleaned again, which increases the work intensity and wastes the polymer slurry. Utility Model Content

Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.
[0007] In view of the problems of the above-mentioned trenchless polymer grouting device, the present utility model is proposed.
[0008] Therefore, the purpose of the present invention is to provide a trenchless polymer grouting device, which is used to solve the problem that the grouting tube of the existing hand-held grouting device is usually short, so the operator needs to bend down and squat to perform grouting, and excessive pressure during grouting will give the grouting tube a reaction force, so the operator needs to press the hand-held grouting device hard, and the operator bends down or squats for a long time to work, with limited force, which is very physically demanding. The reason why the grouting tube of the existing hand-held grouting device is usually short is that if the grouting tube of the hand-held grouting device is long, then when the grouting tube is taken out from one grouting hole and grouting is performed in another grouting hole, the remaining polymer slurry in the grouting tube will flow out of the grouting tube, which needs to be cleaned again, which increases the work intensity and wastes the polymer slurry.
[0009] In order to solve the above technical problems, the present invention provides the following technical solutions: a trenchless polymer grouting device, comprising:

[0028] Reference Figures 1-4 , which is an embodiment of the present utility model, provides a trenchless polymer grouting device, which includes: a carrier unit 100 and a grouting unit 200;
[0029] The carrier unit 100 includes a transport vehicle 101 and a handheld grouting device 104. A slurry storage tank 102 is installed on the transport vehicle 101. A conduit 103 is fixed to and connected to the feed port of the handheld grouting device 104. The end of the conduit 103 away from the handheld grouting device 104 is fixed to and connected to the slurry storage tank 102.
[0030] The grouting unit 200 includes a grouting pipe 201, a connecting pipe 202 is fixed on and connected to the discharge port of the handheld grouting device 104, and the end of the connecting pipe 202 away from the handheld grouting device 104 is fixed and connected to the grouting pipe 201, a pedal 203 is fixed to the bottom of the grouting pipe 201, and a control component 204 is provided in the grouting pipe 201 for controlling the polymer slurry to pass through the grouting pipe 201.
[0031] When in use, when roadbed projects, pavement projects, bridge projects, etc. are not maintained for a long time or are crushed by large vehicles, the road surface will collapse or break, and the road needs to be repaired. Usually, non-excavation repair is performed, mainly by first drilling holes on the road surface to be repaired, and then using a handheld grouting device 104 to inject the polymer slurry in the slurry tank 102 into the drilled holes for repair.
[0032] In addition, the control component 204 includes a baffle 2041 fixed to the bottom of the grouting pipe 201, a plurality of fan-shaped grooves 2042 are opened at equal intervals in the baffle 2041, a plurality of fan-shaped blocking plates 2043 adapted to the fan-shaped grooves 2042 are provided in the grouting pipe 201, and the fan-shaped blocking plates 2043 are located below the fan-shaped grooves 2042, a rectangular groove 205 is opened in the middle of the baffle 2041, a rectangular rod 206 is slidably connected in the rectangular groove 205, a disc 207 is fixed to the bottom of the rectangular rod 206, and a plurality of fan-shaped blocking plates 2043 are fixed to the outside of the disc 207, The height of the fan-shaped blocking plate 2043 is twice the height of the disc 207. After half of the fan-shaped blocking plate 2043 is embedded in the fan-shaped groove 2042, the top of the disc 207 and the bottom of the baffle 2041 fit together. The top of the rectangular rod 206 is rotatably connected to the long rod 208. The long rod 208 passes through the top of the grouting pipe 201 and is located in the grouting pipe 201 for sealing and sliding. A U-shaped frame 209 is fixed to the top of the grouting pipe 201. The end of the long rod 208 extending to the outside of the grouting pipe 201 is fixed with a screw 210. The screw 210 passes through the U-shaped frame 209 and is threadedly connected to the U-shaped frame 209.
[0033] When in use, when injecting polymer slurry into the repair hole, the grouting pipe 201 is first inserted into the repair hole, and then the pedal 203 is stepped on with the foot to inject the polymer slurry in the slurry storage tank 102 into the repair hole through the handheld grouting device 104. When the grouting pipe 201 needs to be pulled out from the repair hole and inserted into another repair hole, the screw 210 is first rotated to move it in the U-shaped frame 209. When the screw 210 moves, it drives the long rod 208, the rectangular rod 206, and the disc 207 to move, so that the disc 207 drives the fan-shaped blocking plate 2043 to move upward, so that the fan-shaped blocking plate 2043 is embedded in the fan-shaped groove 2042, that is, the fan-shaped blocking plate 2043 blocks the fan-shaped groove 2042. At this time, the remaining polymer slurry in the grouting pipe 201 will not be drawn out from the fan-shaped groove The polymer slurry passes through the groove 2042, which avoids the overflow of the polymer slurry. After the grouting pipe 201 is inserted into another repair hole, the screw 210 is rotated in the opposite direction to drive the long rod 208 and the fan-shaped blocking plate 2043 to move downward. When the fan-shaped blocking plate 2043 is removed from the fan-shaped groove 2042, the polymer slurry can pass through the fan-shaped groove 2042 and be injected into the repair hole. After grouting of all the repair holes is completed, the remaining polymer slurry in the last grouting pipe 201 can be injected into the slurry storage tank 102 to avoid waste of resources. It should be noted that the length of the grouting pipe 201 can meet the operator's standing operation, making the grouting work more convenient and labor-saving, and the lengthened design of the grouting pipe 201 will not cause overflow of excess polymer slurry.
[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
