Description

Vehicle for repairing an asphalt concrete pavement

The present invention relates to a vehicle for repairing a partial breakage (porthole) of an Ascon pavement.

Generally, most of the road pavement is packed using ascon, and road pavement that can substitute for the properties of ascon is less than price competitiveness.

The pavement should be properly maintained due to the weather, climatic effects such as water and moisture, load due to traffic volume, and other external factors.

For example, a small hole (hereinafter referred to as "porthole") is generated on the surface of the pavement due to insufficient voltage at the time of construction, quality of the mixture, poor drainage structure, or natural environmental factors.

These portholes are a serious threat to the safety of driving the roads, and there are about 1000 cases of traffic accidents due to the port halls in a year.

In general, the repair work of the porthole is performed by patching and locally repacking the defective portion. Specifically, after the porthole is cut and crushed to a size and removed, the emulsion (asphalt) is sprayed on the porthole, Next, after applying the ascon in the porthole, the porthole repair work is completed by completing the flattening work.

However, such repair work involves many individual devices such as conveying vehicles for carrying the ascon, cleaning vehicles for cleaning the road surface of the pavement, spraying vehicles for spraying the emulsion in the porthole, and compaction devices for flattening and compaction The work is carried out, and each work process requires a lot of manpower and work time.

For example, Patent Document 10-0660577 (Publication Date: December 22, 2006) proposes an apparatus and method for repairing aged paved roads, but, according to road maintenance work, There is a problem in that it requires a lot of manpower.

On the other hand, only a temporary repair is performed to repackage the asphalt after cleaning only the crushing hole at the time of repairing some roads. Such a temporary restoration work may not be lasted for a long time and continuous damage may occur. However, There is an urgent need for improvement.

On the other hand, there is a proposal for installing the equipment necessary for road maintenance on a moving vehicle to minimize the number of people and the time required for the operation. For example, in Patent Publication No. 10-1334516 (Publication Date: 2013.11.28) The present invention proposes an apparatus for repairing a damaged area on a road surface that can perform a function of installing an ascon on a damaged area of a road and spraying a hardening agent on the installed ascon, A separate transportation vehicle is required to supply the cleaning water and the cleaning of the crushed material still requires manual work.

Next, the operator operates the operation unit 431 in the cabin 120 to drive the first working device 200 so that the shredding unit 210 is positioned in front of the cabin 120, and using the shredding unit 210 Crush the perimeter of the portholes. After the crushing operation around the porthole is completed, compressed air is sprayed through the air nozzle 214 to cleanly remove the crushed material.

Next, the second work unit 300 is operated so that the ascon installing unit 310 is located in front of the cabin 120, and a predetermined amount of the emulsified asphalt is sprayed through the emulsified asphalt injection nozzle 314, Is discharged to the porthole and the compaction operation is performed using the roller unit 220 to complete the road maintenance work.

In this way, a series of work processes such as crushing, removing the crushed material, spraying the emulsified asphalt, installing the asphalt concrete, and compaction are performed through the operation part 431 in the cabin 120 positioned immediately adjacent to the working port hole, Therefore, the operator can work while checking the position of the porthole directly with the naked eye of the porthole image taken by the camera, so that the entire road maintenance work can be performed with only one worker.

11 is a configuration diagram showing an application example of a vehicle for repairing an Ascon pavement road according to the present invention.

11, the maintenance vehicle 1 of the present invention includes a storage unit 460 that stores image data, and the storage unit 460 stores image data for a porthole photographed through the first camera 421 / RTI >

For example, the image data of the port hole before the operation is stored in the storage unit 460, and the image data of the port hole in which the maintenance work is completed is stored in the storage unit 460. At this time, Lt; / RTI > As described above, the image data of the portholes before and after the work is recorded in the storage unit 460 as a work log, so that efficient work management can be performed.

Preferably, the video data may be stored together with the position information of the portholes using the GPS module 472 provided in the maintenance vehicle 1. More specifically, the control unit 410 is provided with a transmission / reception unit 471 capable of transmitting and receiving, and time information and position information together with image data before and after the job can be transmitted to the management server 480, ) Can manage the information of the completed porthole in the road maintenance database.

On the other hand, the management server 480 transmits the positional data requiring new road maintenance to the maintenance vehicle 1, and the maintenance vehicle 1 can move to the received position data and proceed with the road maintenance work.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
