Description

Technical Field

[0001] The utility model relates to the technical field of bridge crack repair, in particular to a grouting device for bridge crack repair. Background Technique

[0002] With the increase of the construction time of bridges and the increasing traffic flow, it is inevitable for bridges cast with cement to produce a small number of cracks. Therefore, it is necessary to reinforce the cracks of bridges. Generally, bridge reinforcement refers to restoring or improving the bearing capacity of existing bridges by strengthening components and improving the structural performance, so as to extend their service life and meet the requirements of modern transportation.

[0003] In the existing bridge crack reinforcement technology, generally, multiple embedded parts with equal intervals are pre-buried at the crack, then the crack is locally filled with cement, and then grout is injected into the crack through the through holes above the embedded parts. After the grout cools, the reinforcement effect of the bridge crack can be achieved. However, when grouting the crack that appears under the bridge in this way, because the depth of the crack cannot be detected, and grouting the crack from the bottom up vertically, it may not be known whether the inside of the crack is completely soaked by the grout, thus affecting the quality of crack repair.

[0004] Chinese Patent CN202122099579.X discloses "Municipal Road Bridge Crack Reinforcement Structure", with the publication number CN215562027U. The device includes a backing plate, and a telescopic component is arranged on one side of the backing plate. When repairing a crack, the telescopic component can be extended into the crack to be repaired, and its own length can be stretched or shortened according to the depth of the crack. The telescopic component includes a telescopic cylinder one located outside the telescopic cylinder two and for the telescopic cylinder two to retract. When the telescopic cylinder two touches the deepest part of the crack, it can retract into the telescopic cylinder one. However, this device has some defects: the sleeve of this device contacts the crack, and the telescopic cylinders of this device are not connected. Under the friction force of the telescopic cylinder on the inner wall of the gap, the telescopic cylinder two may retract into the telescopic cylinder one before reaching the bottom of the gap, resulting in inaccurate measurement of the deepest depth of the gap.

[0024] Embodiment 1:

[0025] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a technical solution: a grouting device for bridge crack repair, comprising a conduit 1 for grouting into the crack, the conduit is arranged on a base plate 2, a slider 11 is fixedly connected to the conduit 1, the slider 11 is slidably connected to a matching slide 12, a positioning assembly for positioning the slider 11 is arranged on the slide 12, and the slide 12 is fixedly connected to the base plate 2. A grouting hole is provided at the lower end of the conduit 1.

[0026] The slider 11 is fixedly connected to a paddle plate so that the staff can move the catheter 1 up and down.

[0027] The positioning assembly includes a positioning screw 31 penetrating the wall of the slide slot 12 , a positioning hole matching the positioning screw 31 is formed on the slider 11 , and a plurality of mounting holes 32 matching the positioning screw 31 are formed along the length direction of the slide slot 12 .

[0028] The base plate 2 is provided with a measuring rod 8, and a fixing sleeve 81 is sleeved on the measuring rod 8. The fixing sleeve 81 is fixedly connected to the base plate 2, and a fastening screw 82 is provided on the fixing sleeve 81. The end of the fastening screw 82 contacts the surface of the measuring rod 8. The measuring rod 8 is engraved with scales.

[0029] The lower surface of the base plate 1 is fixedly connected to a plurality of moving wheels 5, and the base plate 2 is fixedly connected to a handrail 6. Four moving wheels 5 are provided and distributed at the four corners of the lower surface of the base plate 2.

[0030] The upper end of the conduit 1 is connected to a slurry delivery hose 7 , and the end of the slurry delivery hose 7 is fixedly connected to a reducer connector 71 .

[0031] In order to further improve the applicability of the device, the reducer 71 can be connected to an air pump or a water pump. When the reducer 71 is connected to the water pump, high-pressure water is sprayed from the lower end of the conduit 1 to clean the cracks for subsequent grouting work.

[0032] When this device is in use, the staff move the device to the crack position, then move the slider 11 so that the lower end of the conduit 1 extends into the deepest part of the crack. Then the staff use the positioning screw 31 to fix the slider 11. Next, the staff reverse the fastening screw 82 to let the measuring rod 8 freely drop to the deepest part of the crack. The staff connect the reducing connector 71 to the concrete slurry conveying pipe, and the concrete emerges from the lower end of the conduit 1 to fill the crack. The staff move the device along the crack to evenly fill the crack. Since the measuring rod 8 can slide up and down, when the height of the measuring rod 8 changes significantly, the depth of this section of the crack changes, and the height of the conduit 1 should be adjusted in time to adapt to the change in the crack depth.

[0033] Embodiment 2:

[0034] As Figure 3 shown, Embodiment 2 is different from Embodiment 1. The positioning assembly includes a lead screw 41 threadedly passing through the slider 11 and a support plate 42 fixedly connected to the end of the chute 12. The lead screw 41 is rotatably connected to the support plate 42, and the upper end of the lead screw 41 is fixedly connected to a handwheel 49. Other parts are the same as those in Embodiment 1.

[0035] When this device is in use, the staff move the device to the crack position, then rotate the handwheel 49 to rotate the lead screw 41, thereby moving the slider 11 so that the lower end of the conduit 1 extends into the deepest part of the crack. Then the staff reverse the fastening screw 82 to let the measuring rod 8 freely drop to the deepest part of the crack. The staff connect the reducing connector 71 to the concrete slurry conveying pipe, and the concrete emerges from the lower end of the conduit 1 to fill the crack. The staff move the device along the crack to evenly fill the crack. Since the measuring rod 8 can slide up and down, when the height of the measuring rod 8 changes significantly, the depth of this section of the crack changes, and the height of the conduit 1 should be adjusted in time to adapt to the change in the crack depth.
