진동흡수공간부를 적용한 터널굴착방법{Tunnel Constructing Method Applying Space For Reducing Vibration}Tunnel excavation method applying vibration absorbing space part {Tunnel Constructing Method Applying Space For Reducing Vibration}

본 발명은 터널굴착방법에 관한 것으로서, 보다 상세하게는 굴착 시 지표면으로 전달되는 진동과 소음을 최소화하여 지면에 설치된 시설물 등을 보호함과 동시에 경제적 측면에서도 유리하도록 한 진동흡수공간부를 구비한 터널굴착방법에 관한 것이다.The present invention relates to a tunnel excavation method, and more particularly, to minimizing vibration and noise transmitted to the ground during excavation, protecting a facility installed on the ground, and at the same time, economically advantageous tunnel excavation having a vibration absorbing space part. It is about a method.

현재 국내에서는 SOC사업 등이 증대함에 따라 지하공간을 활용하기 위하여 지하공간에 사회간접시설인 각종 에너지와 폐기물의 지하저장시설, 통신구, 전력구와 같은 에너지 전달시설 및 광역상수도를 구축하기 위한 도수터널과, 지하철, 철도, 고속철도, 국도 및 고속도로 등 도로교통을 위한 도로터널 등 수많은 터널굴착 작업이 수행되고 있다.At present, as SOC projects increase in Korea, underground tunnels for various energy and waste storage facilities, communication districts, and power districts to utilize underground spaces are used to build underground waterworks. Numerous tunnel excavation works are being carried out, including road tunnels for road traffic such as subways, railways, high-speed railways, national highways and highways.

통상 터널을 굴착하는 방법으로서는 발파에 의한 굴착공법, 굴착면을 천공한 후 기계적 파쇄장치나 화학제를 사용하여 암반에 충격을 주어 무진동으로 파쇄하여 굴착하는 방법 등 여러 형태가 있다.Conventionally, there are various methods for excavating a tunnel, such as an excavation method by blasting, drilling a drilling surface, and then impacting the rock using a mechanical crushing device or a chemical agent to crush and excavate in a non-vibrating manner.

먼저, 발파에 의한 굴착공법은 도 1에 도시된 바와 같이, 완성될 터널(10)의 막장면 중심부에 복수개의 장약공들(1a)을 천공하여서 된 심발부(1)와 상기 심발부(1) 영역의 외측에 복수개의 장약공들(1a)을 천공하여서 확대부 영역을 이루도록 한 후, 상기 심발부(1)의 장약공들(1a)을 발파하여 암반을 1차로 굴착하고, 선굴착된 심발부(1)를 자유면으로 활용하면서 상기 심발부(1)의 외측에 천공된 확대부 영역의 장약공들(1a)을 발파하여 확대부 영역의 암반을 2차로 굴착하도록 한다.First, as shown in FIG. 1, the excavation method using the blasting is performed by drilling a plurality of charge holes 1a in the center of the membrane surface of the tunnel 10 to be completed, and the heart portion 1 and the heart portion 1. ) To form an enlarged area by drilling a plurality of charge holes (1a) on the outside of the area, and then blasted the charge holes (1a) of the cardiac foot (1) to excavate the rock first, pre-excavated While utilizing the heart portion 1 as a free surface, the blast holes 1a of the enlarged portion area drilled on the outside of the heart portion 1 are blasted so as to excavate rocks of the enlarged portion area secondarily.

이러한 발파에 의한 굴착공법은 화약의 구입이 수월하고 운용이 편리한 장점으로 인해 굴착효율과 굴착비용의 경제성 측면에서 있어서 매우 유리하지만, 도 2에서와 같이, 일측 방향으로만 다량의 폭약을 기폭시켜 암반이 외부로 파쇄되도록 하는 형태로 이루어진다.This excavation method by blasting is very advantageous in terms of the efficiency of the excavation efficiency and the excavation cost due to the easy purchase of gunpowder and easy operation, as shown in Figure 2, by detonating a large amount of explosives in one direction only rock It is made in the form to be crushed to the outside.

결국, 이러한 발파방식의 경우에는 발파로 인한 진동이 암반을 타고 사방으로 전달되게 되므로 필연적으로 굴착작업 내내 격심한 진동, 소음이 외부 주위 시설물에까지 전달된다는 문제를 가진다.As a result, in the case of such a blasting method because the vibration caused by the blasting is transmitted to all directions on the rock, inevitably there is a problem that severe vibration, noise is transmitted to the surrounding facilities throughout the excavation work.

특히, 이러한 진동, 소음 및 분진 등은 터널 직상부의 지표면으로 그대로 전파되면서 터널 직상부에 위치하는 구조물, 인체, 가축류, 기기류 등에 악영향을 미치므로 인구와 건물이 밀집된 도심지 내의 건물터파기 및 도로확장, 신설, 지하철, 고속철도, 문화재 인접지역 공사, 재개발지역 등의 공사에서는 집단민원이 빗발치고 있음은 물론 발파허가 조차 얻기 힘들어 공사자체가 힘든 경우도 있었다.In particular, such vibrations, noises, and dusts propagate directly to the surface of the tunnel, which adversely affects structures, humans, livestock, and equipment located in the upper part of the tunnel. In the construction of new buildings, subways, high-speed railroads, construction of adjacent areas of cultural property, and redevelopment areas, collective complaints were not only incurred, but even the blasting permits were difficult.

이에 따라, 진동과 소음 분진이 없이 암반을 파쇄하는 정적 파쇄적인 공법이 요구되고 있으며, 이러한 굴착방법의 일환으로 최근 무진동 파쇄공법이 주로 이용되고 있다.Accordingly, there is a demand for a static crushing method of crushing rock without vibration and noise dust. As part of such an excavation method, a vibration-free crushing method has recently been mainly used.

무진동 파쇄공법은 터널 막장을 천공한 후 천공한 구멍 안에 굴삭기에 장착된 초대형 할암기(B.R.S: Big Rock Splitter)의 바깥(外)날을 삽입하여 내(內)날인 쐐기를 고압의 유압피스톤(2,500~3,500 ton)으로 밀어넣어 암반을 파쇄하도록 하거나, 천공한 구멍 안에 겔 튜브를 주입한 다음 전기뇌관 및 소량의 기폭약으로 화학반응을 촉진시켜 순간적으로 고온, 고압 상태로 전환되는 겔의 힘(이성질체의 호변이성을 이용)을 이용하여 암반을 파쇄하도록 하는 것이다.The vibration-free crushing method inserts the outer blade of a large rock splitter (BRS) mounted on an excavator into a drilled hole after drilling a tunnel face, and uses a high pressure hydraulic piston (2,500). ~ 3,500 ton) to break the rock, or to inject a gel tube into the perforated hole, and then to accelerate the chemical reaction with an electric primer and a small amount of explosives, the force of the gel that instantly switches to a high temperature and high pressure state. Using tautomerism) to break up the rock.

이러한 무진동 파쇄공법은 화약발파로 인한 비산, 폭음압 등이 없으므로 발파에 의한 굴착공법에 비하여 안전하고 소음 및 진동이 적어 환경공해 측면에서 유리하지만, 발파방식과 비교하여 같은 길이당 굴착비용도 증대될 뿐 아니라 굴착효율이 낮아 전체공사기간이 길어져 경제성 측면에서 있어서는 매우 불리하다는 문제가 있다.This vibration-free crushing method is safer than the blasting method because it has no scattering and explosion pressure due to gunpowder blasting, and is advantageous in terms of environmental pollution due to less noise and vibration.However, the excavation cost per length can be increased compared to the blasting method. In addition, there is a problem in that it is very disadvantageous in terms of economic feasibility as the entire construction period is long due to low digging efficiency.

It must be interpreted in terms of meaning and concept.

이하, 본 발명의 일 실시예를 도면을 참조하여 상세히 설명함에 있어, 동일한 구성에 대해서는 동일한 부호를 사용하며, 명료성을 위하여 가능한 중복되지 않게 상이한 부분만을 주로 설명한다.DETAILED DESCRIPTION Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. Like reference numerals refer to like elements, and only different parts will be mainly described so as not to overlap for clarity.

첨부된 도면 중, 도 3은 본 발명 터널굴착방법의 초기단계를 개략적으로 나타낸 정면도이고, 도 4는 본 발명 진동흡수공간부를 적용한 터널굴착방법에 있어서 진동흡수공간부가 형성된 터널을 나타낸 측단면도이다.3 is a front view schematically showing an initial stage of the tunnel excavation method of the present invention, and FIG. 4 is a side cross-sectional view showing a tunnel in which a vibration absorbing space part is formed in the tunnel excavation method using the vibration absorbing space part of the present invention.

도 3에 도시된 바와 같이, 본 발명 터널 굴착방법은 지표면으로 전달되는 진동 및 소음이 최소화되도록 완성될 터널에 있어서 지표면과 가장 가깝게 위치되는 구역에 진동흡수공간부(110)를 굴착하는 단계를 거친다. As shown in Figure 3, the tunnel excavation method of the present invention is subjected to the step of excavating the vibration absorbing space 110 in the region located closest to the ground surface in the tunnel to be completed to minimize the vibration and noise transmitted to the ground surface. .

상기 진동흡수공간부(110)는 통상적으로는, 도 3 및 도 4에 도시된 바와 같이, 완성될 터널의 직상부가 지표면과 가장 가깝게 되므로 완성될 터널의 상부측에 형성된다.The vibration absorbing space 110 is typically formed on the upper side of the tunnel to be completed because the upper portion of the tunnel to be completed is closest to the ground surface, as shown in FIGS. 3 and 4.

그리고, 상기 진동흡수공간부(110)는 진동흡수공간부 이외의 잔여터널부(120)의 굴착작업 후 발생되는 버럭처리를 위하여 작업자가 투입된 후 버럭처리 작업이 가능할 정도의 높이로 굴착된다.In addition, the vibration absorbing space 110 is excavated to a level sufficient to allow a buckle processing operation after the operator is input for the buckle processing generated after the excavation work of the remaining tunnel portion 120 other than the vibration absorbing space portion.

이를 위해, 상기 진동흡수공간부(110)는 통상적으로 2m 정도의 높이로 형성됨이 바람직하다. To this end, the vibration absorbing space 110 is preferably formed to a height of about 2m.

또한, 상기 진동흡수공간부(110)는 진동과 소음의 발생이 최소화 되도록 암반파쇄방식을 통하여 굴착되도록 하는 것이 바람직하다.In addition, the vibration absorbing space 110 is preferably to be excavated through a rock crushing method to minimize the generation of vibration and noise.

여기서, 상기 암반파쇄를 통한 굴착은 상측으로 진동 및 소음이 전달되는 것을 최소화하기 위하여 할암기 등과 같은 장비를 활용하는 무진동 암반파쇄공법이 이용됨이 더욱 바람직할 것이다.Here, the excavation through the rock crushing will be more preferably used for rock-free rock crushing method that utilizes equipment such as a rock rock to minimize the transmission of vibration and noise to the upper side.

따라서, 종래의 일반 화약을 사용하는 발파를 통한 굴착과 비교하여 본 발명 터널굴착방법에 의하면 상기 진동흡수공간부(110)의 굴착 시에 근접한 지표면에 위치하는 진동과 소음에 민감한 시설물들에 전해지는 피해를 최소화할 수 있게 된다.Therefore, according to the tunnel excavation method of the present invention as compared to the excavation through the blasting using the conventional general gunpowder is transmitted to the vibration and noise-sensitive facilities located on the ground surface close to the excavation of the vibration absorbing space 110. Damage can be minimized.

상기 진공흡수공간부(110)의 굴착이 완료되면, 첨부된 도 3 및 도 4에 도시된 바와 같이, 상기 진동흡수공간부(110)의 내부에서 상기 지표면과 반대되는 방향으로 굴착을 단계적으로 진행하여 상기 진동흡수공간부(110)를 제외한 나머지 잔여터널부(120)의 굴착작업이 수행된다.When the excavation of the vacuum absorbing space 110 is completed, as shown in FIGS. 3 and 4, excavation is performed stepwise in a direction opposite to the ground surface inside the vibration absorbing space 110. Excavation work of the remaining tunnel portion 120, except for the vibration absorbing space 110 is performed.

이하에서는 상기 잔여터널부(120)의 굴착작업을 보다 자세히 설명하기로 한다.Hereinafter, the excavation work of the residual tunnel portion 120 will be described in more detail.

먼저, 첨부된 도 4에서와 같이, 상기 진동흡수공간부(110)의 하부로 균열발파용 발파공(125)을 형성 후, 화약을 장착하고 균열발파 작업을 개시한다.First, as shown in Figure 4, after forming the crack blasting hole 125 in the lower portion of the vibration absorbing space 110, the gunpowder is mounted and the crack blasting operation is started.

이렇게 되면, 첨부된 도 5에 도시된 바와 같이, 상기 진동흡수공간부(110)의 하부에 인접된 잔여터널부(120)에 균열이 발생하게 되고, 작업자는 상기 잔여터널부(120)의 암반 등을 별도의 브레이커 장비 등을 활용하여 잘게 쪼갠 후 발생되는 버럭들을 외부로 반출하여 굴착작업을 하게 된다.In this case, as shown in FIG. 5, cracks are generated in the remaining tunnel portion 120 adjacent to the lower portion of the vibration absorbing space portion 110, and the worker is a rock of the remaining tunnel portion 120. After dividing the back using a separate breaker equipment, etc. the excavation work is carried out by taking out the generated buckets to the outside.

한편, 본 발명에 있어서는, 상기 발파작업을 통한 발파 또는 암반 파쇄 시에 발생되는 진동 및 소음이 상기 진동흡수공간부(110)에 의하여 상당부분 감소되어 전달될 수 있게 된다.On the other hand, in the present invention, the vibration and noise generated during the blasting or rock crushing through the blasting operation can be reduced by a substantial portion by the vibration absorbing space 110 can be transmitted.

즉, 일반적인 터널 굴착 시에 적용되는 암반을 완전히 파쇄하여 버리는 일반 발파 공법이 아닌, 암반에 별도의 장비로 긁어낼 수 있을 정도의 균열만을 가하는 균열발파가 적용됨은 물론, 이러한 균열발파 시 발생하는 진동이나 소음 조차도 암반이 구비된 터널의 하부측으로 전달되며, 상기 진동흡수공간부(110)로 전달되는 나머지 진동 및 소음은 진동흡수공간부(110)를 거치면서 대부분 감쇄되는 것이다.That is, instead of the general blasting method that completely crushes the rock applied in the general tunnel excavation, the crack blast that applies only the crack enough to be scraped by a separate equipment is applied to the rock, as well as the vibration generated during the crack blasting. Even noise is transmitted to the lower side of the tunnel provided with rock, and the remaining vibration and noise transmitted to the vibration absorbing space 110 is mostly attenuated while passing through the vibration absorbing space 110.

따라서, 상기 진동흡수공간부(110)에 근접된 지표면에 위치하는 진동 및 소음에 민감한 시설물들에 피해를 끼치지 않으며, 상기한 무진동 굴착방법에 비해 작업시간과 비용을 최소화할 수 있다는 이점이 있다.Therefore, it does not cause damage to the vibration and noise-sensitive facilities located on the ground surface close to the vibration absorbing space 110, there is an advantage that can minimize the work time and cost compared to the vibration-free excavation method described above. .

그리고, 상기 잔여터널부(120)의 굴착은 상기 진공흡수공간부(110)의 굴착이 진행됨과 동시에 형성되므로, 상기 잔여터널부(120) 굴착단계에서 발생된 버럭들을 제거하는 작업이 매우 간편하고 신속하게 이루어질 수 있게 된다.In addition, since the excavation of the residual tunnel portion 120 is formed at the same time as the excavation of the vacuum absorption space portion 110 proceeds, it is very easy to remove the burrs generated in the excavation step of the residual tunnel portion 120. It can be done quickly.

도 7은 본 발명의 이중공법을 통한 터널의 굴착방법에 따라 잔여터널부가 굴착된 상태를 나타내는 터널의 측단면도이다.Figure 7 is a side cross-sectional view of a tunnel showing a state in which the remaining tunnel portion is excavated according to the excavation method of the tunnel through the double method of the present invention.

도 7에 도시된 바와 같이, 공사기간의 단축 및 작업의 편리성을 위하여 상기 진동흡수공간부(110)와 잔여터널부(120)의 굴착작업은 계단 형태로 서로 병행하여 굴착하여 이루어지도록 하는 것이 바람직하다.As shown in FIG. 7, the excavation work of the vibration absorbing space 110 and the remaining tunnel portion 120 is performed in parallel to each other in a step form for shortening the construction period and convenience of work. desirable.

즉, 일정 영역 별로 완성될 터널의 길이방향을 따라서 상기 진동흡수공간부(110)가 굴착되면, 상기 진동흡수공간부(110)의 굴착 중에 발생된 버럭들을 제거하고 버럭들이 정리된 공간에서 다시 1차잔여터널부(120a)의 굴착을 실시한다. That is, when the vibration absorbing space 110 is excavated along the longitudinal direction of the tunnel to be completed for each predetermined area, the blocks generated during the excavation of the vibration absorbing space 110 are removed, and the buffers are arranged again in a space in which they are arranged. Excavation of the tea cup residual tunnel portion 120a is performed.

그리고, 상기 1차잔여터널부(120a)의 굴착 시 발생된 버럭들은 후방으로 이송되어 처리된다. In addition, the barrels generated during the excavation of the primary residual tunnel portion 120a are transported to the rear and processed.

다음으로는, 상기 1차잔여터널부(120a)의 하부에 2차잔여터널부(120b)의 굴착을 실시한다. Next, the secondary residual tunnel portion 120b is excavated in the lower portion of the primary residual tunnel portion 120a.

이때에도 상기 진동흡수공간부(110)의 굴착과 1차잔여터널부(120a)의 굴착은 여전히 진행상태이며, 이와 같은 과정에서 새롭게 발생된 버럭들은 지속적으로 후방으로 이송되어 처리된 후, 상기 2차잔여터널부(120b)의 굴착 시 발생된 버럭들과 함께 후방으로 이송하여 처리된다. At this time, the excavation of the vibration absorbing space 110 and the excavation of the primary residual tunnel portion 120a are still in progress, and the newly generated barrels in this process are continuously transported to the rear and processed. It is processed by transporting the rear with the buckets generated during the excavation of the tea cup remaining tunnel portion 120b.

이렇게 하면, 도 6에 도시된 바와 같이, 계단식으로 상기 진동흡수공간부(110), 1차잔여터널부(120a) 및 2차잔여터널부(120b)가 완성된다. 6, the vibration absorbing space 110, the primary residual tunnel portion 120a and the secondary residual tunnel portion 120b are completed stepwise.

이와 같은 일련의 굴착작업을 연속적으로 반복하면서 상기 진동흡수공간부(110)와 잔여터널부(120)의 굴착구간을 연장시키면 최종적으로 완성될 터널 전부가 굴착된다.Extending the excavation section of the vibration absorbing space 110 and the remaining tunnel portion 120 while continuously repeating the series of excavation operations, all the tunnels to be finally completed are excavated.

한편, 상기 잔여터널부(120)는 1차 및 2차만이 아닌 보다 많은 구간의 잔여터널부로 구획하여 다수 회 차에 걸쳐 터널굴착이 진행될 수도 있음은 물론이다.On the other hand, the residual tunnel portion 120 may be divided into the remaining tunnel portion of more sections than the primary and secondary, tunnel tunnel excavation may be carried out a plurality of times.

특히, 상술한 바와 같이 본 발명에 의하면, 상기 잔여터널부(120)의 굴착 시에 균열발파를 위한 장약공을 수직방향 장약공(125)은 물론 수평방향 장약공(126)과 같이 장약공 및 굴착 등을 위한 자유면이 두 개 이상으로 나타나 상황에 따라 선택적으로 발파 및 굴착이 가능해진다.In particular, according to the present invention as described above, when the residual tunnel 120 is excavated, the charge hole for crack blasting, as well as the vertical charge hole 125 as well as the horizontal charge hole 126 More than two free surfaces for excavation, etc. appear to selectively blast and excavate depending on the situation.

즉, 주위 상황에 따라서 발파 위치 등을 조절하여 진동이 전달되는 방향 등까지도 조절이 가능하게 된다.That is, by adjusting the blasting position according to the surrounding situation, it is possible to adjust even the direction in which the vibration is transmitted.

상기와 같이 구성된 본 발명 진동흡수공간부를 적용한 터널굴착방법에 의하면 완성될 터널에 있어서 보호시설물이 설치된 지표면과 가장 가깝게 위치되는 구간에 터널의 길이방향을 따라서 진동흡수공간부를 선굴착한 다음 잔여터널부를 굴착함으로써 터널 굴착 시 발생되는 진동과 소음이 상기 진동흡수공간부를 통하여 최소화된다.According to the tunnel excavation method using the vibration absorbing space part of the present invention configured as described above, the tunnels are pre-excavated along the longitudinal direction of the tunnel in the section located closest to the ground surface where the protection facility is installed, and then the remaining tunnel part. Excavation minimizes vibration and noise generated when the tunnel is excavated through the vibration absorbing space.

또한, 터널과 지표면과의 위치관계를 고려해 가면서 상기 진동흡수공간부의 굴착 위치를 조정할 수 있으므로 보다 능동적이고 효율적으로 터널 굴착 시 발생되는 진동 및 소음을 차단할 수 있게 된다.In addition, since the excavation position of the vibration absorbing space portion can be adjusted while considering the positional relationship between the tunnel and the ground surface, it is possible to more effectively and efficiently block the vibration and noise generated during the excavation of the tunnel.
