Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, and in particular to a geopolymer grouting reinforcement grouting equipment. Background Technology

[0002] Geopolymer grouting is a construction technique that uses geopolymer materials to reinforce underground spaces or structures. This technique involves injecting geopolymer grout into soil or concrete cracks to form a hard chemical bond, thereby improving the stability and load-bearing capacity of the structure. Geopolymer grouting material is mainly composed of silicate cement as the matrix, mixed with high-performance polymers, water, and additives.

[0003] In the slurry preparation stage, a large amount of powdered and solid raw materials need to be thoroughly and evenly mixed with water. However, the mixing tanks of existing grouting machines are generally arranged vertically. When the raw materials are put into the water surface in the tank, the stirring rod has to overcome a large fluid resistance at the beginning of the start-up, resulting in a low rotation speed. At the same time, the horizontal water flow generated by the horizontally rotating stirring rod is difficult to effectively push the powdered raw materials to sink. As a result, in the initial stage of mixing, the powdered raw materials will briefly form a floating layer on the water surface and cannot quickly come into contact with the water for mixing, which reduces the mixing efficiency and is not conducive to completing the grouting operation quickly and efficiently. Therefore, a geopolymer grouting reinforcement grouting device is proposed. Utility Model Content

[0032] Example 1

[0033] Reference Figures 1-3 The first embodiment of this utility model provides a geopolymer grouting reinforcement grouting device, which generates a downward thrust by a horizontally curved stirring blade, forcing the powdered raw material to quickly leave the water surface and immerse itself in the water body, so as to promote the rapid mixing of the raw material and water. It includes: a drive vehicle 100, a feeding unit 200 and a grouting unit 400.

[0034] The feeding unit 200 is set on the top of the drive vehicle 100. The top of the drive vehicle 100 is also provided with a horizontally distributed mixing unit 300. The feeding unit 200 is used to convey polymer slurry to the mixing unit 300. The mixing unit 300 includes a mixing tank 301 and a servo motor 302 fixedly installed on one side of the mixing tank 301. The output shaft of the servo motor 302 rotates through the mixing tank 301 and is fixedly connected to a plurality of uniformly distributed stirring blades 303. The end of each stirring blade 303 is curved in an arc.

[0035] The grouting unit 400 is installed on the top of the drive vehicle 100, through which the mixed grout is injected.

[0036] The drive vehicle 100 serves as the mobile platform for the entire equipment. The feeding unit 200 is used to transport the geopolymer raw materials into the mixing tank 301. The mixing tank 301 is horizontally positioned, and the output shaft of the servo motor 302 is also horizontally positioned. The servo motor 302 and the mixing tank 301 are sealed by a sealed bearing. When water and powdered raw materials are added to the mixing tank 301, the servo motor 302 drives the stirring blade 303 to rotate. The curved end of the stirring blade 303 is close to the inner wall of the mixing tank 301 but does not contact it. The curved stirring blade 303 can generate a downward thrust to prevent the powdered raw materials from remaining on the water surface and force the powdered raw materials to quickly leave the water surface and immerse themselves in the water body, so as to promote the rapid mixing of raw materials and water. The mixed geopolymer slurry is discharged from the mixing tank 301 into the grouting unit 400, and the geopolymer slurry is injected into the target reinforcement area at a stable pressure and flow rate through the grouting unit 400.

[0037] Example 2

[0038] Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, the feeding unit 200 includes a feeding hopper 201 fixed to the top of the drive vehicle 100. The bottom of the feeding hopper 201 is fixedly connected to a conveying pipe 202. The bottom end of the conveying pipe 202 is fixedly connected to a screw conveyor 203. The bottom of the top of the screw conveyor 203 is fixedly connected to a vertical pipe 204. The bottom end of the vertical pipe 204 is fixedly connected to a mixing tank 301. The wall of the vertical pipe 204 is fixedly connected to a water inlet pipe 205. An electric control valve is sleeved on the water inlet pipe 205.

[0039] The water inlet pipe 205 is connected to the external water supply facility through a quick connector or flange structure. During the water supply process, water flows through the water inlet pipe 205 into the vertical pipe 204. Its flow rate is precisely controlled by the electric control valve installed on the water inlet pipe 205. Then, the powdered and solid raw materials of the geopolymer are put into the feed hopper 201. The raw materials enter the screw conveyor 203 through the conveying pipe 202. The screw conveyor 203 is equipped with a screw conveying rod driven by a motor. The rotation of the screw generates propulsion force, which conveys the raw materials into the vertical pipe 204 at a uniform speed. Then, it enters the horizontally arranged mixing tank 301, and the arc-shaped stirring blade 303 driven by the servo motor 302 performs deep stirring, thereby achieving a thorough and uniform mixing of the raw materials and water.

[0040] The bottom of the feed hopper 201 converges downwards towards the top of the conveying pipe 202, causing the raw materials to automatically flow and converge towards the conveying pipe 202. A vibration motor 206 is fixedly installed on one side of the feed hopper 201.

[0041] The bottom of the feed hopper 201 adopts a conical opening design, which, together with the vibration motor 206 on the side wall, can effectively prevent the raw materials from accumulating or stagnating in a local area of ​​the feed hopper 201. The vibration allows the raw materials in the feed hopper 201 to flow quickly into the conveying pipe 202, so that the screw conveyor 203 can convey the materials.

[0042] Example 3

[0043] Reference Figure 1 and Figure 2 This is the third embodiment of the present invention. Unlike the previous embodiment, the mixing unit 300 also includes a support frame 304 fixedly connected to the top of the drive vehicle 100. The mixing barrel 301 is fixedly fixed in the support frame 304 in a horizontal position. A discharge pipe 305 is fixedly connected to one side of the mixing barrel 301. An electric control valve is sleeved on the discharge pipe 305.

[0044] The support frame 304 is used to support the mixing tank 301 and make it horizontally distributed. The mixture in the mixing tank 301 is discharged through the discharge pipe 305, and the discharge pipe 305 is closed by the electric control valve to block the pipeline during feeding and mixing to prevent slurry leakage.

[0045] Each stirring blade 303 has multiple through holes on its surface. A gate-shaped plate 306 is fixedly connected to the output shaft of the servo motor 302. The gate-shaped plate 306 is close to the inner wall of the mixing tank 301 but does not contact the mixing tank 301.

[0046] When the stirring plate 303 rotates, the slurry passes through the through hole, causing the slurry to form a jet under the action of pressure difference, so as to promote secondary mixing in the mixing tank 301 and improve its mixing effect. The servo motor 302 can drive the gate plate 306 to rotate, so as to push the raw materials to mix through the gate plate 306 and prevent some solid particles from continuously settling at the bottom of the tank wall, thereby further ensuring the mixing effect.

[0047] In addition, two symmetrically distributed diversion pipes 307 are fixedly connected to the discharge pipe 305, and the ends of the two discharge pipes 305 and the diversion pipes 307 away from the mixing tank 301 are all bent downwards.

[0048] The diversion pipe 307 is used to share the discharge pressure of the discharge pipe 305, so that part of the slurry in the discharge pipe 305 can be discharged through the two diversion pipes 307. With the downward bending design, the slurry flowing in the discharge pipe 305 and the diversion pipe 307 can be buffered and slowed down to reduce the slurry flow rate and avoid slurry splashing.

[0049] Example 4

[0050] Reference Figure 1 and Figure 3This is the fourth embodiment of the present utility model. Unlike the previous embodiment, the grouting unit 400 includes a collection bucket 401 fixedly connected to the top of the drive vehicle 100. The side wall of the collection bucket 401 is fixedly connected to a grout discharge pipe 402, and a pressure pump 403 is sleeved on the grout discharge pipe 402.

[0051] The slurry discharged from the discharge pipe 305 and the diversion pipe 307 is discharged into the collection tank 401. The slurry in the collection tank 401 automatically flows into the slurry discharge pipe 402, and after being pressurized by the pressure pump 403, the slurry is discharged from the slurry discharge pipe 402. The slurry discharge pipe 402 can be connected to an external pipeline to inject the geopolymer slurry into the target reinforcement area at a stable pressure and flow rate.

[0052] In addition, the top of the collection bucket 401 is fixedly connected to two symmetrically distributed slide rails 404, and a filter plate 405 is slidably provided between the two slide rails 404.

[0053] The slurry discharged from the discharge pipe 305 and the diversion pipe 307 will be filtered by the filter plate 405 to remove large particles or undissolved raw materials from the slurry. The two symmetrically distributed diversion pipes 307 can work with the discharge pipe 305 to evenly feed the slurry onto the surface of the filter plate 405, thereby making full use of the filter plate 405 for large-area filtration. The filter plate 405 can be slid out between the two slide rails 404 for cleaning.

[0054] During use, clean water is added to the mixing tank 301 through the water inlet pipe 205. Then, the geopolymer raw material is put into the feed hopper 201 and the vibration motor 206 is turned on so that the raw material in the feed hopper 201 flows quickly into the conveying pipe 202. Then, the raw material is conveyed at a constant speed to the vertical pipe 204 by the screw conveyor 203, and then the raw material is conveyed to the mixing tank 301 by the vertical pipe 204. Next, the servo motor 302 drives the stirring blade 303 to rotate. The curved end of the stirring blade 303 can generate a downward thrust to force the powdered raw material to quickly leave the water surface and immerse itself in the water body. The slurry will pass through the through hole to form a jet to promote secondary mixing in the mixing tank 301. The rotating gate plate 306 can prevent some solid particles from continuously settling at the bottom of the tank wall, thereby ensuring the mixing effect.

[0055] After mixing is complete, the electric control valve of the discharge pipe 305 is opened, allowing the mixed slurry to be discharged through the discharge pipe 305 and the two diversion pipes 307. At this time, the slurry will be filtered by the filter plate 405 to remove large particles or undissolved raw materials. The filtered slurry is discharged into the collection tank 401. After the mixing tank 301 is emptied, the electric control valve of the discharge pipe 305 is closed, and water and raw materials are added to the mixing tank 301 again for mixing. The slurry in the collection tank 401 will flow into the discharge pipe 402 and be pressurized by the pressure pump 403 before being discharged to be injected into the target reinforcement area.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
