Problems solved by technology

Since the concrete road is completely solidified at this time, the concrete road cannot be driven by vehicles, because the curing film cannot be laid by vehicles, etc.
At present, the laying of the curing film relies on manually placing the curing film in rolls on the concrete road, and then pushing the curing film to roll and lay it out, which is time-consuming

Embodiment 1

[0037] Embodiment 1: a kind of rapid prototyping concrete pavement maintenance tool, such as figure 1 , comprising a vehicle frame 1, a first roller 21 rotatably connected to the vehicle frame 1, a second roller 22 rotatably connected to the vehicle frame 1, a push frame 3 fixed at one end of the vehicle frame 1, and rotatably connected to the other side of the vehicle frame 1 The push roller 23 at one end, the first roller 21 and the second roller 22 are located between the push frame 3 and the push roller 23 .

[0038] Such as figure 1The vehicle frame 1 includes mounting plates 11 on both sides, and the two ends of the first roller 21, the second roller 22, and the pushing roller 23 are respectively inserted into the mounting plates 11 on both sides to rotate relative to the mounting plates 11.

[0039] Such as figure 1 , the first roller 21 and the second roller 22 have the same diameter, and their rotation axes are on the same level, so that the lowest points of the fir...

Abstract

The invention discloses a rapid prototyping concrete pavement maintenance tool and maintenance method, comprising a vehicle frame, a first roller shaft rotatably connected to the vehicle frame, a second roller shaft rotatably connected to the vehicle frame, and a push frame fixed at one end of the vehicle frame , Rotate the push roller connected to the other end of the frame, the first roller and the second roller are located between the push frame and the push roller, and the lowest points of the first roller and the second roller are located on the same horizontal plane , the lowest point of the push roller is higher than the lowest point of the first roller. Place the film roll in front of the push roller, and the film passes through the push roller, the first roller and the second roller; the push frame drives the frame to move, and the push roller pushes the film roll to unfold, and then the first roller and the second roller The shaft is pressed against the unfolded film; since the first roller and the second roller have a large contact area with the concrete pavement, it is not easy to cause the concrete pavement to sag.

Description

technical field [0001] The invention relates to the field of road surface maintenance, in particular to a rapid prototyping concrete road surface maintenance tool and a maintenance method. Background technique [0002] After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be transformed into stable crystals. Lack of sufficient cohesion, resulting in flaking or powdering off the concrete surface. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the maintenance of the initial stage after concrete pouring is very important. The concrete should be cured immediately after the final setting, and the d...
