절삭부재 및 이를 이용한 도로포장의 그루브 공법{CUTTING MEMBER AND GROOVE METHOD FOR PAVEMENT USING THE SAME}Cutting member and groove method for road pavement using the same {CUTTING MEMBER AND GROOVE METHOD FOR PAVEMENT USING THE SAME}

본 발명은 토목 분야에 관한 것으로서, 상세하게는 도로포장의 그루브 공법에 관한 것이다.The present invention relates to the field of civil engineering, and more particularly, to a groove construction method of road pavement.

도로포장의 그루브 공법이란, 다이아몬드와 같은 강한 재질의 블레이드가 장착된 절삭장치를 이용하여 도로포장 노면을 절삭하여 요철구조를 형성하는 공법을 말하며, 이는 우천 시 배수촉진, 교통소음저감 및 미끄럼저항 특성 개선 등의 효과를 얻을 수 있도록 한다.The road pavement groove method refers to a method of forming an uneven structure by cutting the pavement road surface using a cutting device equipped with a blade of a strong material such as diamond, which promotes drainage in rainy weather, reduces traffic noise, and features slip resistance. Make it possible to obtain effects such as improvement.

특히, 항공기가 활주로 및 유도로에서 고속 이동시, 포장 표면상태가 제동과 기동에 영향을 미치는 바, 미끄럼 저항, 노면배수, 해빙촉진 등의 효과를 향상하여 항공기 운항 안전성을 확보하기 위하여, FAA(미연방항공청)를 비롯한 여려 해외 공항에서는 공항 활주로 및 유도로 포장의 그루브 공법에 관한 연구가 활발하게 진행되고 있다.In particular, when an aircraft moves at high speed on the runway and taxiway, the pavement surface condition affects braking and maneuvering.In order to improve the effects such as sliding resistance, road surface drainage, and sea ice promotion, FAA (U.S. Aviation Administration) and other overseas airports are actively conducting research on the groove construction method for paving runways and taxiways.

도 1은 종래의 그루브 공법에 사용되는 절삭부재(A)(드럼, 헤드라고도 함)의 사시도이고, 도 2는 절삭부재(A)의 정면도이다.1 is a perspective view of a cutting member A (also referred to as a drum or head) used in a conventional groove method, and FIG. 2 is a front view of the cutting member A.

종래의 절삭부재(A)는, 다수의 칼날부(100)가 외주를 둘러 열지어 형성된 블레이드(A1)를 구비하고, 다수의 블레이드(A1) 및 스페이서(A2)가 교호적으로 적층되어 결합됨으로써 형성되어, 모터에 의해 고속회전하면서 콘크리트 도로포장의 표면을 소정 깊이 절삭하여 요철구조를 형성하도록 구성된다(도 3).The conventional cutting member (A) has a blade (A1) formed by opening a plurality of blade portions (100) around the outer periphery, and a plurality of blades (A1) and spacers (A2) are alternately stacked and combined. It is formed, and is configured to form an uneven structure by cutting the surface of the concrete road pavement to a predetermined depth while rotating at high speed by a motor (Fig. 3).

한편, 종래에는 그루브 공법에 의한 도로포장의 홈을 사각형 단면구조의 사각형 홈(10)으로 형성하는 것이 일반적이었으나, 최근에는 이에 비해 성능이 향상된 역사다리꼴 단면구조의 역사다리꼴 홈(20)으로 형성하는 사례가 증가하고 있다.On the other hand, conventionally, it was common to form the groove of the road pavement by the groove method as a rectangular groove 10 having a rectangular cross-sectional structure, but recently, the inverted trapezoidal groove 20 having an improved performance compared to this is formed. Cases are increasing.

FAA(미연방항공청)의 시험 및 연구결과를 살펴보면, 역사다리꼴 홈(20) 구조의 그루브가 사각형 홈(10) 구조의 그루브에 비해, 미끄럼 마찰력, 배수성, 내구성 등의 성능이 향상되는 것으로 나타나 있다.Looking at the results of tests and research conducted by the FAA (Federal Aviation Administration), it is shown that the grooves of the historical trapezoidal groove 20 structure improve the performance of sliding friction, drainage, and durability compared to the grooves of the square groove 10 structure.

사각형 홈(10)을 형성하는 경우에는 사각형 단면을 갖는 칼날부(110a)를 적용하고(도 4,5), 역사다리꼴 홈(20)을 형성하는 경우에는 역사다리꼴 단면을 갖는 칼날부(110b)를 적용한다(도 6,7).In the case of forming the rectangular groove 10, the blade portion 110a having a rectangular cross-section is applied (Figs. 4 and 5), and in the case of forming the inverse trapezoidal groove 20, the blade portion 110b having an inverted trapezoidal cross-section Is applied (Figs. 6 and 7).

그런데 이러한 종래에는 그루브 공법은 다음과 같은 문제가 있었다.However, in the prior art, the groove method has the following problems.

블레이드(A1)에 형성된 다수의 칼날부(100)는 절삭작업의 경과와 함께 마모 되므로, 일정량의 작업 이후에는 새로운 블레이드(A1)로 교체하여 작업하여야 한다.Since the plurality of blade portions 100 formed on the blade A1 wear out with the progress of the cutting operation, after a certain amount of work, it must be replaced with a new blade A1.

사각형 홈(10)을 형성하기 위한 사각형 칼날부(100a)의 경우에는, 그 단부가 어느 정도 마모되더라도(도 4의 점선 참조) 사각형 형상을 유지하므로, 교체주기를 길게 할 수 있다.In the case of the rectangular blade portion 100a for forming the rectangular groove 10, even if the end thereof is worn to some extent (refer to the dotted line in FIG. 4), the rectangular shape is maintained, so that the replacement period can be lengthened.

그러나 역사다리꼴 홈(20)을 형성하기 위한 역사다리꼴 칼날부(100b)의 경우에는, 그 단부가 마모됨에 따라(도 6의 점선 참조) 단면의 형상이 변형되고, 변형된 칼날부를 이용하여 작업을 지속하는 경우, 최초의 역사다리꼴 홈(20)에 비해 깊이가 얕게 변형된 구조의 역사다리꼴 홈(20)을 얻게 된다.However, in the case of the reverse trapezoidal blade portion 100b for forming the reverse trapezoidal groove 20, the shape of the cross section is deformed as the end is worn (refer to the dotted line in Fig. 6), and the operation is performed using the modified blade part. In the case of continuing, the inverse trapezoidal groove 20 having a structure whose depth is shallower than that of the first inverse trapezoidal groove 20 is obtained.

따라서 설계된 정확한 치수의 역사다리꼴 홈(20)을 얻기 위해서는, 블레이드의 교체주기를 짧게 하여야 하는데, 이는 시공비용의 증가를 초래한다는 문제로 귀결된다.Therefore, in order to obtain the designed inverse trapezoidal groove 20 of the correct dimensions, the replacement cycle of the blade must be shortened, which leads to a problem that increases the construction cost.

위 종래기술의 도면부호는 당해 종래기술의 설명에 대하여만 한정되는 것으로 한다.The reference numerals of the prior art are limited to the description of the prior art.

본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 역사다리꼴 홈 구조의 그루브를 시공하면서도, 블레이드의 교체주기를 증대하여 시공비용을 절감할 수 있도록 하는 도로포장의 그루브 공법을 제시하는 것을 그 목적으로 한다.The present invention was derived in order to solve the above problems, and proposes a groove construction method for road pavement that enables to reduce construction cost by increasing the replacement cycle of blades while constructing grooves of an inverted trapezoidal groove structure.

도 8 이하에 도시된 바와 같이, 본 발명은 기본적으로, 다수의 칼날부(100)가 외주를 둘러 열지어 형성된 블레이드(A1)를 구비하고, 다수의 블레이드(A1) 및 스페이서(A2)가 교호적으로 적층되어 결합됨으로써 형성되고, 모터에 의해 고속회전하면서 도로포장의 표면을 소정 깊이 절삭하여 요철구조를 형성하는 도로포장의 그루브 공법에 사용되는 절삭부재(A)에 관한 것이다.As shown in Fig. 8 below, the present invention basically includes a blade (A1) formed by opening a plurality of blade portions 100 around the outer periphery, and a plurality of blades (A1) and spacers (A2) are interchangeable. It relates to a cutting member (A) used in a groove method of a road pavement, which is formed by being laminated and combined in a row, and rotates at high speed by a motor and cuts the surface of the road pavement to a predetermined depth to form an uneven structure.

여기서, '도로'는 공항의 활주로, 유도로 등이 모두 포함된 개념이고, '도로포장'은 시멘트 콘크리트 포장, 아스팔트 콘크리트 포장이 모두 포함된 개념이다.Here,'road' is a concept that includes all runways and taxiways of an airport, and'road pavement' is a concept that includes both cement concrete pavement and asphalt concrete pavement.

칼날부(100)는, 횡단면을 기준으로 단부에 바닥면형성부(111)가 형성된 판부(110); 판부(110)의 양측면에 다수가 간격을 두고 돌출형성됨과 아울러, 횡단면을 기준으로 단부에 빗면형성부(121)가 형성된 돌출부(120);를 포함하여 구성된다(도 8,9).The blade portion 100 includes a plate portion 110 having a bottom surface forming portion 111 formed at an end thereof based on a cross section; A plurality of protrusions are formed on both sides of the plate portion 110 at intervals, and a protrusion 120 having an inclined surface forming portion 121 formed at an end thereof based on a cross section (FIGS. 8 and 9).

횡단면을 기준으로, 판부(110)의 바닥면형성부(111)와 양측의 돌출부(120)의 빗면형성부(121)의 조합에 의해 역사다리꼴 단면구조가 형성된다(도 11).Based on the cross-section, the inverse trapezoidal cross-sectional structure is formed by the combination of the bottom surface forming portion 111 of the plate portion 110 and the inclined surface forming portions 121 of the protruding portions 120 on both sides (FIG. 11).

바닥면형성부(111)는 하단이 편평한 바닥면을 형성하는 사각형 구조를 의미하고, 빗면형성부(121)는 측면에 빗면을 형성하기 위한 삼각형 구조 또는 단부가 약간 모따기된 구조를 의미한다.The bottom surface forming part 111 refers to a square structure in which the bottom surface forms a flat bottom surface, and the inclined surface forming part 121 refers to a triangular structure for forming an inclined surface on the side surface or a structure in which the end is slightly chamfered.

종래기술에 의한 역사다리꼴 칼날부(100b)는 칼날부 전체가 역사다리꼴 단면을 갖는 일체형 구조를 취하므로, 그루브 공사 중 그 단부가 마모됨에 따라(도 6의 점선 참조) 단면의 형상이 변형되고, 변형된 칼날부를 이용하여 작업을 지속하는 경우, 최초의 역사다리꼴 홈(20)에 비해 깊이가 얕게 변형된 구조의 역사다리꼴 홈(20)을 얻게 된다는 문제가 있었다.Since the reverse trapezoidal blade portion 100b according to the prior art takes an integral structure having a reverse trapezoidal cross section as a whole, the shape of the cross section is deformed as the end of the blade is worn during groove construction (see dotted line in FIG. 6), In the case of continuing the work using the deformed blade, there is a problem that the inverted trapezoidal groove 20 having a structure that is deformed to be shallower than the first inverse trapezoidal groove 20 is obtained.

그루브 공사 중 칼날부의 각 부위의 마모율은 칼날부의 각 부위의 강도에 반비례하고, 그 칼날부의 각 부위와 도로포장 표면이 접촉하는 접촉면적의 누적값에 비례한다.The wear rate of each part of the blade part during groove construction is inversely proportional to the strength of each part of the blade part, and is proportional to the cumulative value of the contact area between each part of the blade part and the road pavement surface.

종래의 일체형 역사다리꼴 칼날부(100b)의 경우에는, 그 바닥면과 측면(빗면)이 동일한 재질에 의해 일체로 형성되므로 각 부위의 강도가 동일하다.In the case of the conventional integral reverse trapezoidal blade portion 100b, the strength of each portion is the same since the bottom surface and the side surface (comb surface) are integrally formed of the same material.

또한, 칼날부의 바닥면은 홈의 초기 형성시부터 완성시까지 지속적으로 도로포장 표면에 접촉함에 비해, 칼날부의 측면(빗면)은 홈이 어느 정도 형성된 이후에 비로소 그 홈의 측면(빗면)과 접촉하게 되므로, 칼날부의 바닥면의 접촉면적의 누적값이 칼날부의 측면(빗면)의 접촉면적의 누적값에 비해 훨씬 크다.In addition, while the bottom surface of the blade part continuously contacts the road pavement surface from the initial formation of the groove to the completion, the side surface (bevel surface) of the blade part only contacts the side surface (bevel surface) of the groove after the groove is formed to some extent. Therefore, the cumulative value of the contact area of the bottom surface of the blade is much larger than the cumulative value of the contact area of the side (comb) of the blade.

따라서 상술한 종래의 일체형 역사다리꼴 칼날부(100b)의 경우에는, 그 칼날부의 바닥면의 마모율이 측면(빗면)의 마모율에 비해 훨씬 큼에 따라, 도 6과 같이 칼날부의 단면의 형상이 변형된다.Therefore, in the case of the conventional integral inverse trapezoidal blade portion 100b described above, the shape of the cross-section of the blade portion is deformed as shown in FIG. 6 as the wear rate of the bottom surface of the blade portion is much larger than the wear rate of the side (beveled surface). .

본 발명은 칼날부 전체가 역사다리꼴 단면을 갖는 일체형 구조를 취하는 것이 아니라, 횡단면을 기준으로, 판부(110)의 바닥면형성부(111)와 양측의 다수의 돌출부(120)의 빗면형성부(121)의 조합에 의해 역사다리꼴 단면구조가 형성되도록 함과 아울러, 판부(110)의 양측면에 간격을 두고 형성된 다수의 돌출부(120)에 의해 위 빗면형성부(121)(측면)가 형성되도록 한다는 특징이 있다.In the present invention, the entire blade portion does not take an integral structure having an inverted trapezoidal cross section, but based on the cross-section, the bottom surface forming portion 111 of the plate portion 110 and the inclined surface forming portion of the plurality of protrusions 120 on both sides ( In addition to forming the inverse trapezoidal cross-sectional structure by the combination of 121), the upper inclined surface forming portion 121 (side surface) is formed by a plurality of protrusions 120 formed at intervals on both sides of the plate portion 110. There are features.

이러한 구조를 취하는 경우, 일체형으로 형성된 칼날부(100)의 판부(110)의 바닥면형성부(111)(바닥면)의 강도에 비해, 일체형 구조를 취하지 않고 다수의 돌출부(120)에 의해 형성되는 빗면형성부(121)(측면)의 강도가 전체적으로 약하게 된다.When taking such a structure, compared to the strength of the bottom surface forming portion 111 (bottom surface) of the plate portion 110 of the blade portion 100 formed integrally, it is formed by a plurality of protrusions 120 without taking an integral structure. The strength of the inclined surface forming portion 121 (side) is generally weakened.

따라서 상술한 바와 같이, 기본적으로 칼날부의 바닥면의 접촉면적의 누적값에 비해 칼날부의 측면(빗면)의 접촉면적의 누적값은 작지만, 칼날부의 빗면형성부(121)(측면)의 강도가 전체적으로 약해지므로, 칼날부(100)의 판부(110)의 바닥면형성부(111)(바닥면)의 마모율과 양측 돌출부(120)의 빗면형성부(121)의 마모율이 비슷하게 된다.Therefore, as described above, basically, the cumulative value of the contact area of the side (bevel) of the blade is small compared to the cumulative value of the contact area of the bottom of the blade, but the strength of the inclined surface forming portion 121 (side) of the blade is generally Since it becomes weak, the wear rate of the bottom surface forming portion 111 (bottom surface) of the plate portion 110 of the blade portion 100 and the abrasion rate of the inclined surface forming portions 121 of both protrusions 120 are similar.

이에 따라 그루브 공사 중 칼날부(100)의 마모가 발생하더라도, 그 바닥면과 측면(빗면)의 전체적인 형상이 유지됨에 따라, 일정한 형상의 역사다리꼴 홈(20)을 얻을 수 있다는 효과가 있다(도 11).Accordingly, even if abrasion of the blade portion 100 occurs during the groove construction, as the overall shape of the bottom and side surfaces (beveled surfaces) is maintained, there is an effect that the inverted trapezoidal groove 20 of a certain shape can be obtained (Fig. 11).

칼날부(100)의 다수의 돌출부(120)의 빗면형성부(121)(측면)의 강도가 전체적으로 약한 구조를 안정적으로 구현하기 위해서는, 정면을 기준으로 돌출부(120)가 삼각형 구조로 형성되는 것이 바람직하다(도 10).In order to stably implement a structure in which the strength of the inclined portion 121 (side) of the plurality of protrusions 120 of the blade portion 100 is generally weak, the protrusion 120 is formed in a triangular structure based on the front surface. It is preferable (Fig. 10).

구체적으로는, 다수의 돌출부(120)가 열지어 형성됨에 따라, 다수의 산부(122)와 다수의 골부(123)가 교호적으로 형성된 구조를 취하는 것이 바람직하다(도 10).
이때, 산부(122)의 횡단면은 역사다리꼴 단면구조로 형성되고(도 11), 골부(123)의 횡단면은 판부(110)의 바닥면형성부(111)에 의해 사각형 단면구조로 형성된다.(도 12)Specifically, as the plurality of protrusions 120 are formed in a row, it is preferable to take a structure in which a plurality of peaks 122 and a plurality of valleys 123 are alternately formed (FIG. 10).
At this time, the cross-section of the ridge 122 is formed in an inverted trapezoidal cross-sectional structure (FIG. 11), and the cross-section of the valley 123 is formed in a rectangular cross-sectional structure by the bottom surface forming portion 111 of the plate portion 110. Fig. 12)

산부(122)의 외측 단부가 뾰족한 구조를 취하는 경우, 그 뾰족한 부분의 마모가 일찍 발생함에 따라 일정한 형상의 역사다리꼴 홈(20)이 형성되지 않을 수 있는데, 이를 방지하기 위해서는 산부(122)의 외측 단부에 모따기부(122a)가 형성되는 것이 바람직하다(도 13).When the outer end of the ridge 122 has a sharp structure, as the abrasion of the sharp part occurs early, the inverted trapezoidal groove 20 of a certain shape may not be formed. To prevent this, the outside of the ridge 122 It is preferable that a chamfer 122a is formed at the end (FIG. 13).

칼날부(100)의 빗면형성부(121)(측면)의 강도가 전체적으로 약한 구조는 상술한 바와 같은 구조에 의해 구현될 수도 있지만, 돌출부(120)가 판부(110)에 비해 강도가 약한 재질에 의해 형성되도록 하는 방식에 의해서도 구현할 수 있다.The structure in which the strength of the beveled portion 121 (side) of the blade portion 100 is generally weak may be implemented by the above-described structure, but the protrusion 120 is made of a material having weaker strength than the plate portion 110. It can also be implemented by a way to be formed by.
