본 고안은 터널과 같은 지중굴착을 하는데 사용되는 실드에 관한 것으로, 특히 지반에 투입되는 후드부와 꼬리부의 휨변형대응강도가 향상될 뿐 아니라 매서실드를 병렬로 설치할 때 매서실드가 이탈하지 않고 일정간격으로 유지될 수 있도록 된 지중굴착용 매서실드에 관한 것이다.The present invention relates to a shield used for underground excavation, such as a tunnel. In particular, the flexural deformation resistance strength of the hood part and the tail part applied to the ground is improved, and the method shield does not deviate when the method shield is installed in parallel. It relates to an underground drilling method shield that can be maintained at intervals.
터널막장과 지중을 굴착할 때 시공되는 매서실드(Messer Shield)공법은, 터널형상에 맞춰 제작한 지보재위에다 매서실드를 병렬로 배열한 다음, 각 매서실드를 유압추진기로 1개씩 순차로 밀어넣으면서 막장을 굴착하는 한편, 매서실드후 방의 굴착면에다 토류판을 대고 지보재로 받쳐가는 공법으로써, 이러한 공법에 사용되는 매서실드로서는 제3도와 제4도에 도시된 본 출원인이 실용신안등록출원 제93-3087호로 제안한 것을 들 수 있는 바, 이는 후드부 상부면(1a)의 압끝쪽이 첨예한 쐐기형상을 한 후드부(1)의 뒷쪽에, 하부판(3)의 중앙에 축방향을 따라 일정간격으로 형성된 다수의 추진걸이구멍(3a)을 사이에 두고 수직으로 고정되는 단면이 ㄱ자형상으로 된 소정길이의 세움부재(4)와 이 세움부재(4)의 외측에 위치하여 이 세움부재(4)의 상부면(4a)를 지지하도록 된 경사판(5) 및 상기 세움부재(4)의 상단부를 이어주는 연결판(6)으로 이루어진 추진부(2)가 결합되어 이어지는 한편, 이 추진부(2)의 뒷쪽에는 하부면 중심축을 따라 수직방향으로 수직보강판(8)이 장착되어 단면이 T자형상을 한 꼬리부(7)가 결합된 구조로 되어 있다.The Messer Shield method, which is constructed when excavating tunnel face and ground, arranges the shields in parallel on the support fabricated according to the tunnel shape, and then pushes each method shield one by one with a hydraulic propeller. In addition, the method of applying the earth plate to the excavation surface of the room after the method is supported by the support material, and the method of the method used in such a method is shown in FIGS. 3 and 4 by the applicant of the Utility Model Registration Application No. 93-3087 It is proposed by the arc, which is formed at regular intervals along the axial direction at the center of the lower plate 3 on the back side of the hood portion 1, which has a sharp wedge-shaped tip end portion of the hood upper surface 1a. An upright member 4 having a predetermined length having an L-shaped cross section fixed vertically with a plurality of propelling hook holes 3a interposed therebetween and positioned at an outer side of the upright member 4 Supporting face 4a The propulsion part 2 consisting of the inclined plate 5 and the connecting plate 6 which connects the upper end of the upright member 4 is coupled to each other, while the rear side of the propulsion part 2 is perpendicular to the lower surface central axis. The vertical reinforcing plate 8 is mounted in the direction, and the tail portion 7 having a T-shaped cross section is coupled.
따라서 각 매서실드를 설치할 때, 각각 상기 세움부재(4)의 높이가 다른 2가지 종류의 매서실드(a, a')를 제작해서 교대로 배치하게 되면, 각 세움부재(4, 4')의 상부면(4a, 4a')끝부분이 상·하로 겹쳐지도록 하기만 하면 상호간의 연결이 이루어지게 되므로 대상지반내로의 압입이 쉽게 이루어지게 되고, 인접된 매서실드(a, a')의 연결부위에서의 추진저항마찰력이 줄여지는 한편, 꼬리부(7)의 휩변형이 크게 감소되게 된다.Therefore, when installing each method shield, if two kinds of method shields (a, a ') having different heights of the uprights (4) are produced and arranged alternately, the respective uprights (4, 4') If the upper surface (4a, 4a ') end only overlaps up and down, the mutual connection is made easily, so it is easy to press-fit into the target ground, and at the connection of adjacent mass shields (a, a') While the propulsion resistance of the frictional force is reduced, whip deformation of the tail 7 is greatly reduced.
그러나 이러한 지중굴착용 매서실드의 구조는, 후드부(1)와 꼬리부(7)의 휨변형대응강도가 부족하여 굴진시에 휨변형이 발생하기 쉽고, 또 각 매서실드를 병렬로 설치할 때 세움부재(4, 4')의 상부면(4a, 4a') 끝부분이 일정간격으로 겹쳐지지 못하게 되는 결점이 있게 된다.However, the structure of the underground excavation method shield is lacking in the flexural deformation-response strength of the hood part 1 and the tail part 7, so that the bending deformation easily occurs during the excavation, and it is established when installing each method shield in parallel. There is a drawback that the ends of the upper surfaces 4a and 4a 'of the members 4 and 4' do not overlap at regular intervals.
이에 본 고안은 상기와 같은 제반결점을 해소하기 위해 안출된 것으로, 후드부와 꼬리부의 상부면에 일정길이의 환봉이 일정간격으로 2개 또는 3개가 용접되어, 휨변형대응강도가 한층더 향상됨과 더불어 매서실드를 설치할 때 일정간격으로 겹쳐지게 됨으로써 이탈이 일어나지 않도록 된 지중굴착용 매서실드를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above-mentioned defects, and two or three round bars of a predetermined length were welded to the upper surface of the hood part and the tail part at regular intervals, and thus the flexural deformation resistance was further improved. In addition, the purpose is to provide a method for underground excavation method that the separation does not occur by overlapping at a predetermined interval when installing the method shield.
상기와 같은 목적을 달성하기 위한 본 고안은, 상부면의 앞쪽끝이 첨예한 쐐기형상을 한 후드부의 뒷쪽에, 중앙에 축방향을 따라 일정간격으로 형성된 다수의 추진걸이구멍을 사이에 두고 수직으로 고정되는 단면이 ㄱ자형상을 한 소정길이의 세움부재와 이 세움부재의 외측에 위치해서 상단부재를 지지하도록 된 경사판 및 상기 세움부재의 상단부를 이어주는 연결판으로 이루어진 추진부가 결합되어 이어지는 한편, 이 추진부의 뒤에는 하부면 중심축을 따라 수직방향으로 수직보강판이 장착되어 단면이 T자형으로 된 꼬리부로 이루어진 지중굴착용 매서실드에 있어서, 상기 후드부와 꼬리부에 폭방향 중심선에서 일정간격 떨어진 위치에 소정직경과 길이를 가진 환봉이 용접되어 보강된 구조로 되어 있다.The present invention for achieving the above object is, vertically with a plurality of propelling hook holes formed at regular intervals along the axial direction at the center on the rear side of the hood portion having a sharp wedge-shaped front end of the upper surface. The propulsion part consisting of an upright member having a predetermined length having an L-shape, an inclined plate positioned on the outside of the upright member to support the top member, and a connecting plate connecting the top end of the upright member is coupled to each other. In the underground excavation method shield consisting of a tail portion having a T-shaped cross-section with a vertical reinforcement plate in the vertical direction along the central axis of the lower surface behind the portion, the hood portion and the tail portion at a predetermined distance away from the center line in the width direction Round bars with over length are welded and reinforced.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도 (a), (b)는 각각 본 고안 지중굴착용 매서실드의 제1실지예를 정면도와 평면도로 나타낸 것으로, 종래기술인 제3도 및 제4도에서와 같은 부위에는 동일한 참조부호를 붙이면서 그에 대한 설명은 생략한다.Figures 1 (a) and (b) show a first practical example of the method for the underground drilling method, respectively, in the front view and the plan view, and the same reference numerals are applied to the same parts as those in the prior art FIGS. The description thereof is omitted.
후드부 상부면(1a)의 앞끝쪽이 첨예한 쐐기형상을 한 후드부(1)의 뒷쪽에, 하부판(3)의 중앙에 축방향을 따라 일정간격으로 형성된 다수의 추진걸이구멍(3a)을 사이에 두고 수직으로 고정되는 단면이 ㄱ자형상을 한 소정길이의 세움부재(4)와 이 세움부재(4)의 외측에 위치하여 이 세움부재(4)의 상부면(4a)를 지지하도록 된 경사판(5) 및, 상기 세움부재(4)의 상단부를 이어주는 연결판(6)으로 이루어진 추진부(2)가 결합되어 이어지는 한편, 이 추진부(2)의 뒤에는 하부면 중심축을 따라 수직방향으로 수직보강판(8)이 장착되어 단면이 T자형상을 이루도록 된 꼬리부(7)로 이루어진 지중굴착용 매서실드에 있어서, 상기 후드부(1)의 상부면(1a)과 꼬리부(7)의 상부면(7a)에 각각 양끝이 일치하도록 배치됨과 더불어 폭방향중심선에서 일정거리를 갖는 위치에 소정직경과 길이의 환봉(9)이 용접되어 굽힙강도가 보강된 구조로 되어 있다.On the rear side of the hood portion 1 having a sharp wedge shape in front of the upper portion 1a of the hood portion, a plurality of propelling hook holes 3a formed at regular intervals along the axial direction in the center of the lower plate 3 are provided. An upright member 4 having a predetermined length having an L-shaped cross section secured therebetween and an inclined plate positioned outside the upright member 4 to support the top surface 4a of the upright member 4. (5) and a propelling portion 2 consisting of a connecting plate 6 connecting the upper end of the upright member 4 is coupled to each other, while behind the propelling portion 2 vertically along the central axis of the lower surface. In the underground excavation method shield consisting of a tail portion 7 is mounted to the reinforcement plate 8 to form a T-shaped cross section, the upper surface (1a) and the tail portion 7 of the hood portion (1) Both ends of the upper surface 7a are arranged to coincide with each other, and a predetermined diameter is provided at a position having a predetermined distance from the center line in the width direction. The round bar 9 of length and length is welded, and it has a structure which reinforced bending strength.
따라서 상기 후드부(1)와 꼬리부(7)에 용접고정된 환봉(9)에 의해 매서실드(A)를 유압실린더로 굴진시킬 때 휨변형이 일어나지 않게 된다.Therefore, the bending deformation does not occur when the method shield A is pushed into the hydraulic cylinder by the round bar 9 welded to the hood 1 and the tail 7.
또 제2도 (a), (b)는 각각 세움부재의 높이를 달리하여 시공할 때 제1실시예와 함께 사용되는 제2실시예를 도시한 것으로, 이 제2실시예에서는 이 후드부(1)의 상부면(1a)축중심선 위치에 별도의 환봉(9a)이 후드부(1)의 앞끝과 면일치되도록 1개 용접되는 한편, 후드부(1)와 꼬리부(7)의 양쪽끝에서 일정거리 만큼 안쪽으로 떨어지면서 매서실드(A')의 중심선에서 일정거리 떨어진 위치에 환봉(9)이 매서실드(A')의 길이방향으로 용접된 구조로 되어 있다.2 (a) and 2 (b) show a second embodiment which is used together with the first embodiment when constructing with different heights of the standing members. In this second embodiment, the hood part ( One round bar 9a is welded at the shaft center line position of the upper surface 1a so as to coincide with the front end of the hood 1, while both ends of the hood 1 and the tail 7 are The inner rod 9 is welded in the longitudinal direction of the method shield A 'at a position away from the center line of the method shield A' while falling inward by a predetermined distance.
따라서 상기 후드부(1)의 중앙선 위치에 용접되어 고정시켜진 환봉(9a)이 매서실드(A')의 강도를 향상시키는 역할을 하는 한편, 후드부(1)와 꼬리부(7)의 양쪽끝에서 일정거리 떨어지고 매서실드(A')의 폭방향 가장자리에서 안쪽으로 일정거리 떨어진 위치에 용접고정된 환봉(9)이 매서실드의 강도를 향상시킴과 더불어 상기 제1실시예에 따른 매서실드(A)를 본 제2실시예의 매서실드(A, A')와 병렬로 설치하는 경우 제1실시예의 매서실드(A)에 구비된 세움부재(4)의 상부면(4a) 옆가장자리가 제2실시예의 매서실드(A')에 설치된 환봉(9)에 안내되어 일정거리를 유지하면서 굴진하게 됨으로 굴진시 매서실드(A, A')간의 이탈이 방지될 수 있게 된다.Therefore, the round bar 9a, which is welded and fixed at the center line position of the hood part 1, serves to improve the strength of the method shield A ', while both the hood part 1 and the tail part 7 A round bar 9 welded and fixed at a position away from the end and spaced inward from the widthwise edge of the method shield A 'improves the strength of the method shield and the method shield according to the first embodiment ( When A) is installed in parallel with the method shields A and A 'of the second embodiment, the edge of the upper surface 4a of the upright member 4 provided in the method shield A of the first embodiment is the second. Guided to the round bar (9) installed in the method shield (A ') of the embodiment is to be maintained while maintaining a certain distance to be able to prevent the separation between the method shield (A, A') when drilling.
이상 설명한 바와 같이 본 고안에 의하면, 지반에 굴진되는 매서실드의 후드부(1)와 꼬리부(7)의 휨변형대응강도가 향상될 뿐만 아니라, 매서실드(A, A')를 병렬로 시공할 때 매서실드가 이탈되지 않고 일정간격으로 설치될 수 있는 효과가 있다.As described above, according to the present invention, not only the flexural deformation resistance of the hood portion 1 and the tail portion 7 of the method shielded in the ground is improved, but the method shields A and A 'are constructed in parallel. When doing this, there is an effect that the method shield can be installed at regular intervals without being separated.
