본 발명은 토목 공사에 사용되는 장치 분야에 관한 것으로서, 상세하게는, 콘크리트 도로포장의 표면을 소정 깊이 절삭함과 아울러, 콘크리트 포장의 표면에 미세한 요철구조를 형성하기 위한 그라인딩 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of devices used in civil engineering, and more particularly, to a grinding device for cutting a surface of concrete road pavement to a predetermined depth and forming a fine uneven structure on the surface of concrete pavement.

콘크리트 포장의 그라인딩 공법이란, 다이아몬드와 같은 강한 재질의 블레이 드가 장착된 그라인딩 장치를 이용하여 도로포장 노면을 절삭함으로써 평탄성을 개선하는 공법을 말하며, 승차감을 증진시키고, 교통소음저감 및 미끄럼저항 특성 개선 등의 효과를 얻을 수 있도록 한다.Grinding method of concrete pavement refers to a method of improving flatness by cutting road pavement using grinding devices equipped with blades made of strong materials such as diamonds. To get the effect.

도로포장의 표면에는 다양한 파장 대역의 요철이 존재하는데, 이는 마이크로 텍스쳐(0.5mm 이하), 매크로 텍스쳐(0.5mm ~ 5cm), 메가 텍스쳐(5cm ~ 50cm), 러프니스(50cm 이상) 등으로 나누어 볼 수 있다.On the surface of the pavement, there are irregularities of various wavelength bands, which are divided into micro textures (0.5 mm or less), macro textures (0.5 mm to 5 cm), mega textures (5 cm to 50 cm), and roughness (50 cm or more). Can be.

포장의 공용성능인 평탄성, 미끄럼저항성, 소음특성에 영향을 미치는 표면조직의 파장은 다양한 대역에 걸쳐 존재하는데, 이들 중 메가 조직과 러프니스 대역은 불리한 영향을 미치는 대역이며, 매크로 조직과 마이크로 조직은 유리한 영향을 미치는 대역으로 알려져 있다.The wavelengths of the surface tissues affecting the common performance of pavement, flatness, slip resistance, and noise characteristics, exist in various bands. Among them, the mega and roughness bands are adversely affected. It is known as a band with beneficial effects.

도로교통소음을 유발하는 요인은 크게 엔진음 등의 기계음과, 타이어와 포장 표면의 접촉으로 인해 발생하는 소음으로 나누어 볼 수 있으며, 특히 고속으로 주행하는 도로에서는 타이어와 포장 표면의 접촉에 의한 소음이 주된 요인으로 작용한다.Factors that cause road traffic noise can be largely divided into mechanical noise such as engine noise and noise generated by contact between tires and pavement surfaces. Especially, on roads traveling at high speeds, noise caused by contact between tires and pavement surfaces It is a major factor.

타이어와 포장 표면의 접촉에 의한 소음은 다시 타이어 측벽부의 진동음, 타이어와 포장 표면의 접촉면에서 발생하는 소음, 에어 펌핑음 등으로 나누어 볼 수 있다.The noise caused by the contact between the tire and the pavement surface can be divided into the vibration sound of the tire side wall portion, the noise generated from the contact surface between the tire and the pavement surface, and the air pumping sound.

측벽부의 진동음은 주로 러프니스 파장 대역의 표면조직이 존재할 경우 커지게 되므로, 이는 그러한 파장 대역의 요철을 제거함으로써 해소할 수 있다.Since the vibration sound of the side wall portion becomes large mainly in the presence of the surface texture of the roughness wavelength band, this can be solved by removing the unevenness of such wavelength band.

에어 펌핑음은 타이어가 포장 표면과 접촉시 순간적으로 그 사이에 갇힌 공 기가 높은 압력상태에서 해제되면서 발생하는 것이므로, 포장 표면에 매크로 조직 대역의 공극을 형성시킴으로써 감소시킬 수 있다. Air pumping noise is generated when the tire is in contact with the pavement surface and the air trapped therebetween is released under high pressure and can be reduced by forming a void in the macrotissue zone on the pavement surface.

콘크리트 포장의 그라인딩 공법은 이와 같은 원리를 이용한 것으로서, 그라인딩 장치에 의해 포장 표면을 소정 깊이 절삭함으로써 평탄성을 증대시키고, 포장 표면에 매크로 조직 대역의 요철구조를 형성함으로써, 우수한 미끄럼저항성, 소음특성을 얻을 수 있도록 한다.Grinding method of concrete pavement uses this principle, and it improves flatness by cutting pavement surface to a certain depth by grinding device, and obtains excellent slip resistance and noise characteristics by forming uneven structure of macrostructure band on pavement surface. To help.

도 1,2는 콘크리트 포장의 그라인딩 공법에 사용되는 그라인딩 장치를 도시한 것이다.1 and 2 illustrate grinding apparatuses used in the grinding method of concrete pavement.

도시된 바와 같이, 그라인딩 장치는 크게 본체부(100), 구동부(200), 그라인딩부(300), 제어부에 의해 구성된다.As shown, the grinding apparatus is largely composed of the main body 100, the driving unit 200, the grinding unit 300, the control unit.

구동부(200)는 그라인딩 장치를 구동시키기 위한 구성으로서, 본체부(100)에 장착된 앞바퀴(210) 및 뒷바퀴(220), 이들 바퀴를 구동시키기 위한 구동 엔진(230)에 의해 구성되며, 그라인딩 장치가 그라인딩부(300)의 그라인딩 작업을 수행하기에 적합한 속도로서 일정하게 진행할 수 있도록, 제어부에 의해 제어된다.The driving unit 200 is configured to drive the grinding apparatus, and is configured by the front wheel 210 and the rear wheel 220 mounted on the main body unit 100 and the driving engine 230 for driving these wheels. Is controlled by the control unit so that it can proceed constantly at a speed suitable for performing the grinding operation of the grinding unit 300.

그라인딩부(300)는 상기 구동부(200)에 의한 그라인딩 장치의 구동 중 도로의 표면을 그라인딩하기 위한 구성으로서, 콘크리트 포장의 표면을 그라인딩하도록 앞바퀴(210)와 뒷바퀴(220) 사이에 장착된 그라인딩 헤드(310), 그 그라인딩 헤드(310)를 구동하는 그라인딩 엔진(320)에 의해 구성된다.Grinding unit 300 is a configuration for grinding the surface of the road during the driving of the grinding device by the drive unit 200, the grinding head mounted between the front wheel 210 and the rear wheel 220 to grind the surface of the concrete pavement 310, a grinding engine 320 driving the grinding head 310.

깊이조절바퀴(330)는 그라인딩 헤드(310)의 인접 후방에 장착되어, 그라인딩 헤드(310)가 도로의 표면을 지나치게 깊이 절삭하는 것을 방지하도록 한다.Depth adjustment wheel 330 is mounted adjacent to the rear of the grinding head 310, to prevent the grinding head 310 to cut the surface of the road too deep.

그라인딩 헤드(310)는 도 3,4에 도시된 바와 같이, 다수의 블레이드(311) 및 스페이서(312)가 교호적으로 적층되어 결합한 구조를 취하는데, 도 5에 도시된 바와 같은 블레이드(311)의 커터부(311a)는 탄소강과 다이아몬드의 복합재질에 의해 형성된다.As shown in FIGS. 3 and 4, the grinding head 310 has a structure in which a plurality of blades 311 and spacers 312 are alternately stacked and coupled to each other. The blades 311 as illustrated in FIG. The cutter portion 311a is formed of a composite material of carbon steel and diamond.

이러한 구조를 취하는 그라인딩 헤드(310)에 의해 콘크리트 표면에 대한 그라인딩 작업을 실시한 후에는 도 6,7에 도시된 바와 같은 요철구조의 콘크리트 표면을 얻게 된다.After the grinding work on the concrete surface is performed by the grinding head 310 having such a structure, the concrete surface of the concave-convex structure as shown in FIGS. 6 and 7 is obtained.

여기서, G를 절삭부 폭, A를 랜드부 폭, H를 랜드부 높이, D를 절삭깊이라 한다.Here, G is a cutting part width, A is a land part width, H is a land part height, and D is a cutting depth.

그라인딩 장치에 의한 절삭작업을 수행하다 보면, 블레이드(311)의 절삭에 의해 형성되는 양 절삭부 사이의 영역에 얇은 폭의 핀(P)이 형성되고, 이러한 핀(P) 부분이 양 블레이드(311)의 진동에 의해 절단되어 제거됨에 따라 자연스럽게 D의 깊이만큼 도로의 표면이 절삭되는데, 이로 인하여 도로의 평탄성이 개선되는 효과를 얻을 수 있다.When the cutting operation by the grinding device is performed, a thin fin P is formed in an area between both cutting portions formed by the cutting of the blade 311, and the pin P portion is formed by both blades 311. The surface of the road is naturally cut by the depth of D as it is cut and removed by the vibration of), thereby improving the flatness of the road.

이러한 그라인딩 장치는 트레일러(10)에 의해 견인되어 작업장소까지 이동하며(도 1), 작업장소에 이르러 트레일러(10)와 분리되어 그라인딩 작업을 수행하게 된다(도 2).Such a grinding device is towed by the trailer 10 and moves to the work place (FIG. 1), and is separated from the trailer 10 to the work place to perform the grinding work (FIG. 2).

이와 같이 작업장소까지 이동하는 동안 그라인딩 헤드(310) 등의 구성이 지표면에 접촉하는 경우 파손의 우려가 있다.As such, when the configuration of the grinding head 310 or the like comes into contact with the ground surface while moving to the work place, there is a risk of damage.

따라서 이동 중에는 이송용 뒷바퀴(12)가 하강하여 트레일러(10)의 이송용 앞바퀴(11)와 동일 평면상에서 구동하도록 함으로써 그라인딩 헤드(310) 등이 지표면과 접촉하는 것을 방지하고(도 1), 이동이 완료되어 트레일러(10)와 분리된 후에는 이송용 뒷바퀴(12)가 상승하여 그라인딩 장치의 앞바퀴(210) 및 뒷바퀴(220), 그라인딩 헤드(310) 등이 지표면에 접촉하도록 하는 구성을 취한다(도 2).Therefore, during the movement, the transport rear wheel 12 is lowered to drive on the same plane as the transport front wheel 11 of the trailer 10, thereby preventing the grinding head 310 and the like from contacting the ground surface (FIG. 1). After this is completed and separated from the trailer 10, the transport rear wheel 12 is raised so that the front wheel 210 and the rear wheel 220, the grinding head 310, etc. of the grinding device come into contact with the ground surface. (FIG. 2).

그런데, 이와 같은 구성을 취하는 종래의 그라인딩 장치는 다음과 같은 점에서 문제로 지적되어 왔다.By the way, the conventional grinding apparatus which has such a structure has been pointed out as a problem at the following points.

도 8에 도시된 바와 같이, 트레일러(10)에 의한 그라인딩 장치의 이동작업을 원활히 하기 위하여, 이송용 뒷바퀴(12) 사이의 간격은 그라인딩 헤드(310)의 그것에 비해 넓은 구성을 취한다.As shown in FIG. 8, in order to facilitate the movement of the grinding device by the trailer 10, the spacing between the transport rear wheels 12 takes a wider configuration than that of the grinding head 310.

또한, 그라인딩 작업 중, 이송용 뒷바퀴(12)는 그라인딩 장치의 앞바퀴(210), 뒷바퀴(220), 그라인딩 헤드(310) 등과 함께 지표면에 접촉하는 구성을 취하게 되는데, 도 9에 도시된 바와 같이, 이송용 뒷바퀴(12)가 접촉하는 부위에 요철(A), 단차 등이 형성되어 있는 경우, 그라인딩 장치 전체의 흔들림을 유발하므로, 그라인딩 헤드(310)에 의한 그라인딩 작업을 원활하게 진행하지 못하는 원인이 된다는 문제점이 그것이다.In addition, during the grinding operation, the transport rear wheel 12 is in contact with the ground surface together with the front wheel 210, the rear wheel 220, the grinding head 310 and the like of the grinding device, as shown in Figure 9 , If the unevenness (A), step, etc. is formed in the contact area with the rear wheel 12 for transport, cause the shaking of the entire grinding device, cause the grinding work by the grinding head 310 does not proceed smoothly This is the problem.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 그라인딩 헤드에 의한 그라인딩 작업을 더욱 원활하게 진행할 수 있도록 하는 그라인딩 장치를 제시함을 그 목적으로 한다.The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a grinding device that allows the grinding operation by the grinding head to proceed more smoothly.
