Problems solved by technology

Among them, the method of asphalt drip irrigation can repair pavement cracks of different widths and shapes, and the cracks have a longer service life after repairing; but the operation is complicated, and slotting and expansion are required for cracks with smaller widths, which consumes a lot of manpower and material resources
The crack subsidy method is a method of directly subsidizing cracks by using sealing materials. It is easy to operate. Generally, sealing materials have strong anti-corrosion and waterproof effects; Puncture damage, not suitable for sealing wide cracks

Embodiment 1

[0056] like Figure 1~2 as shown, figure 1 It is a schematic diagram of the bottom of the car body of the multifunctional road surface crack filling locomotive; figure 2 It is a schematic diagram of the connection of the multifunctional pavement crack filling machine.

[0057] The invention provides a multifunctional road crack filling machine, which includes:

[0058] The car body is a movable vehicle, and the chassis of the car body is equipped with tires 10;

[0059] Electronic surveillance devices, including two sets of cameras;

[0060] Among them, the first group of cameras 5 are fixed on both sides of the crack cleaning device 4 at the bottom of the car body 1, and are used to locate the position of the crack on the road surface and its extension state, and monitor the crack cleaning condition;

[0061] The second group of cameras 6 are fixed on both sides of the gun head 7 of the pressure injection caulking device at the bottom of the car body 1 and the rubber pre...

Embodiment 2～3

[0081] The target area in Example 1 is set as an upslope and a downslope, and other conditions are the same as in Example 1.

[0082] Pressure injection joint filling test

Embodiment 4

[0084] We put the multifunctional pavement crack filling machine in the flat slope area with an average width of pavement cracks>2cm for detection, and set the threshold N to 2cm. The method steps of the multifunctional pavement crack filling machine of the present invention for road surface filling are as follows:

[0085] Step 1. The multi-functional pavement crack filling machine is driving in the target area, the electronic monitoring device sends the monitoring signal of the average crack width > 2cm to the signal processing device, and the crack identification sensor sends the average crack width > 2cm sensing signal to the signal processing device;

[0086] Step 2, the signal processing device analyzes and processes the monitoring signal of the electronic monitoring device and the sensing signal of the crack identification sensing device respectively, and transmits the converted video image and / or detection information to the control center;

[0087] Step 3. According t...

Abstract

The invention discloses a multifunctional pavement crack filling machine and a crack filling method. The joint filling machine includes: a car body, an electronic monitoring device, a crack identification sensor device, a signal processing device, a control center, a crack cleaning device, and a pressure injection irrigation device. Seam device, crack tape sticking device. The multifunctional road surface crack filling machine provided by the present invention can automatically locate and identify road surface cracks. The multifunctional road surface crack filling machine can locate the position of cracks through continuous images, and control the corresponding nozzles to inject asphalt or glue rollers to paste joint glue. Realize automatic work without manual operation. At the same time, in the joint filling method of the present invention, different road surface crack repair schemes can be intelligently selected according to the road surface crack conditions, and the asphalt pouring technology and crack subsidy technology are combined, which not only saves human resources, improves work efficiency, but also reduces the risk of traffic accidents. social benefits and promotional value.

Description

technical field [0001] The invention relates to the technical field of pavement crack repairing, in particular to a multifunctional pavement crack filling machine and a crack filling method. Background technique [0002] With the rapid development of my country's highway transportation, various grades of highways are spread all over the country. During the long-term use of the road, the road surface will be damaged to varying degrees. Relevant departments need to use special equipment for road maintenance, such as multi-functional road surface crack filling machines, etc. to repair the damaged road surface. In general, the multi-functional pavement crack filling machine is used together with a blower or a thermal spray gun. The existing multi-functional pavement crack filling machine usually uses a liquefied gas heating system to melt the asphalt or joint glue quickly. Through the pressure of the asphalt pump The material is discharged from the discharge port to achieve the...
