Problems solved by technology

[0007] Aiming at the problem in the prior art that the asphalt poured after the crack is cut is not easy to bond with the crack as a whole, the present invention provides a high-efficiency joint filling machine for road cracks and its repair method. Different from the prior art, the inner wall of the crack is not Realize asphalt pouring under the premise of neat cutting, rely on and adhere to the uneven inner wall of the crack, enhance the traction force between the asphalt and the crack, ensure the bonding firmness between the poured asphalt and the inner wall of the crack, and prevent the asphalt from coming out

Embodiment 1

[0044] Such as Figure 1 to Figure 7 As shown, a high-efficiency joint filling machine for road cracks includes a joint filling machine body 1 and an asphalt spray gun 2 used in conjunction with the joint filling machine body 1. The rear end of the joint filling machine body 1 is provided with a handrail 101, and the front end of the joint filling machine body 1 A mounting frame 3 is provided, and the mounting frame 3 is an L-shaped structure composed of horizontal plates and vertical plates.

[0045] The asphalt spray gun 2 includes a feed pipe 201 and a gun head 202. The connection between the feed pipe 201 and the gun head 202 is provided with a pressure-rotation conversion channel group 4. The overall shape of the pressure-rotation conversion channel group 4 is similar to a wedge, and its width is from front to back. Gradually, the pressure-to-rotation conversion channel group 4 is distributed with a plurality of channels 401 for conveying asphalt, and the internal size of...

Embodiment 2

[0055] On the basis that the basic technical solution of Embodiment 1 remains unchanged, a vacuum cleaner 9 and a dust suction pipe 901 communicating with the vacuum cleaner 9 are provided on the caulking machine body 1, and the lower end of the dust suction pipe 901 extends to the bottom of the gun head 202. On the rear side, the particles and impurities in the cracks are sucked out in advance. The way of dust suction is more environmentally friendly than the way of blowing dust, but the requirements for the vacuum cleaner 9 are higher, because the negative pressure reduction rate of the vacuum cleaner is very high, and it is far away from the dust suction. The dust and particles exceeding 50mm in the pipe 901 are almost not affected by the negative pressure, so a special structure must be adopted to ensure the absorption effect. Specifically, the lower end of the dust suction pipe 901 is covered with an arc-shaped dust cover 904, and the dust cover 904 is used to cover Live i...

Embodiment 3

[0059] On the basis that the basic technical solution of Embodiment 1 or 2 remains unchanged, in S step 4, the dimensions of the several channels 401 in the pressure-to-transformation channel group 4 along the transverse direction in the horizontal plane are all the same, and the longitudinal dimensions in the horizontal plane are the same as before. Gradually decrease backwards to ensure that the two track bars 8 can be parallel to each other, so that the slide plate 203 with constant width slides stably in the track bar 8 all the time, and the gun head 202 uses the slide plate 203 at its upper end to slide and fit in the pressure-rotation conversion channel group. 4 On the track bar 8 provided on the lower end surface, the front and rear parts of the slide plate 203 are used to block the channel 401 that is not connected to the gun head 202.

Abstract

The invention relates to an efficient pouring machine and a repair method for highway cracks, and belongs to the technical field of pavement repair. The machine comprises a pouring machine body and anasphalt spray gun matched with the pouring machine body for use, wherein an armrest is arranged at the rear end of the pouring machine body; a mounting rack is arranged at the front end of the pouring machine body, and the lower end of the asphalt spray gun extends to the lower part of the mounting rack; the asphalt spray gun comprises a guide pipe and a gun head, a pressure-turning channel shifting group is arranged at the joint of the guide pipe and the gun head, width of the pressure-turning channel shifting group is reduced gradually from front to back, multiple channels are distributed in the pressure-turning channel shifting group, inside dimensions of the channels on the front side are larger than those of the channels on the rear side, and the lower end surface of the pressure-turning channel shifting group is a convex arc surface; a slide plate capable of sliding oppositely to the convex arc surface is mounted at the upper end of the gun head, and the other end of the gun head extends to the lower part of the mounting rack. On the basis that crack width changes irregularly, the cracks with different widths can be filled in a targeted manner by the machine capable of adapting to crack width change.

Description

technical field [0001] The invention relates to the technical field of road surface repair, in particular to a high-efficiency crack filling machine for road cracks and a repair method thereof. Background technique [0002] In the damage of highway bridges, the most common is highway cracks. Highway cracks are cracks in the surface layer or cracks in the surface layer caused by the subsidence of the base. When cracks appear in the road, rainwater and groundwater will enter the foundation layers more smoothly. The vehicle is constantly rolling, and the erosion effect of the water infiltrated into the foundation is superimposed, which greatly aggravates the damage progress of the roadbed, resulting in faster damage to the more damaged road. In areas with dense vehicle traffic, tiny cracks and subsidence will expand rapidly, resulting in obvious damage. Under the influence of repeated rolling by vehicles, the cracks and wave pits in the lower road layer will gradually expand, a...
