Title (EN) FAULT FRACTURE ZONE REINFORCEMENT METHOD FOR ROCK TBM TUNNEL
(FR) PROCÉDÉ DE RENFORCEMENT DE ZONE DE FRACTURE DE FAILLE POUR TUNNEL DE TUNNELIER ROCHEUX
(KO) 암반 TBM 터널의 단층파쇄구간 보강방법
Abstract:
(EN) Disclosed is a fault fracture zone reinforcement method for a rock TBM tunnel. A fault fracture zone reinforcement operation is performed during a rock tunnel excavation operation using a rock tunnel excavation apparatus comprising: an excavation body comprising a rotating cutter head and a forward movement part for moving the rotating cutter head forward; a gripper body for supporting the excavation body by closely attaching to a rock tunnel surface when the excavation body moves forward; and a segment erector interposed between the rotating cutter head of the excavation body and the gripper body. The fault fracture zone reinforcement operation comprises: a first step (S1) for connecting a segment to the segment erector; a second step (S2) for closely attaching the segment erector having the segment connected thereto to a rock tunnel surface located on a fault fracture zone by rotating the segment erector; and a third step (S3) for coupling and fixing a set anchor to the segment closely attached to the rock tunnel surface, wherein the fault fracture zone reinforcement operation comprises a segment construction step (S4) for constructing a plurality of segments in a 360-degree direction around the circular rock tunnel surface located on the fault fracture zone by repeatedly performing the first to third steps, wherein the segment construction step (S4) is performed such that, by rotating the segment erector having the segment connected thereto, the segment rotates, and thus a plurality of segments are assembled and installed so as to not overlap with each other and have the lateral surfaces thereof closely attach with each other.
(FR) L'invention concerne un procédé de renforcement de zone de fracture de faille pour un tunnel de tunnelier rocheux. Une opération de renforcement de zone de fracture de faille est effectuée pendant une opération d'excavation de tunnel rocheux à l'aide d'un appareil d'excavation de tunnel rocheux comprenant : un corps d'excavation comprenant une tête de coupe rotative et une partie de déplacement vers l'avant pour déplacer la tête de coupe rotative vers l'avant ; un corps de système de serrage pour supporter le corps d'excavation par fixation étroite à une surface de tunnel rocheux lorsque le corps d'excavation se déplace vers l'avant ; et un érecteur de segment interposé entre la tête de coupe rotative du corps d'excavation et le corps de système de serrage. L'opération de renforcement de zone de fracture de faille comprend : une première étape (S1) pour relier un segment à l'érecteur de segment ; une seconde étape (S2) pour fixer étroitement l'érecteur de segment ayant le segment relié à celui-ci à une surface de tunnel rocheux située sur une zone de fracture de faille par rotation de l'érecteur de segment ; et une troisième étape (S3) pour accoupler et fixer un ancrage défini au segment étroitement fixé à la surface de tunnel rocheux, l'opération de renforcement de zone de fracture de faille comprenant une étape (S4) de construction de segments pour construire une pluralité de segments dans une direction à 360 degrés autour de la surface de tunnel rocheux circulaire située sur la zone de fracture de faille en effectuant de façon répétée les première à troisième étapes, l'étape (S4) de construction de segments étant réalisée de sorte que, en faisant tourner l'érecteur de segment ayant le segment relié à celui-ci, le segment tourne et ainsi de multiples segments sont assemblés et installés de façon à ne pas se chevaucher les uns les autres et ont leurs surfaces latérales qui se fixent étroitement entre elles.
(KO) 본 발명은 암반 TBM 터널의 단층파쇄구간 보강방법이 개시되는 것으로, 회전커터헤드와 상기 회전커터헤드를 전진시키는 전진이동부를 갖는 굴착체와, 상기 굴착체가 전진이동할 때 암반터널면에 밀착되어 상기 굴착체를 지지하는 그리퍼체와, 상기 굴착체의 회전커터헤드와 상기 그리퍼체 사이에 구비되는 세그먼트이랙터를 갖는 암반터널 굴착장치를 이용하여 암반터널의 굴착작업 시 단층파쇄구간에 대한 보강작업에 있어서, 세그먼트이랙터에 세그먼트를 연결하는 제1공정(S1); 세그먼트가 연결된 세그먼트이랙터를 회전시켜 단층파쇄구간에 위치되는 암반터널면에 밀착하는 제2공정(S2); 암반터널면에 밀착된 세그먼트에 세트앙카를 체결하여 고정하는 제3공정(S3)으로 이루어지며, 상기 제1공정 내지 제3공정을 반복적으로 진행하여 단층파쇄구간에 위치되는 원형의 암반터널면에 대해 360도 방향으로 복수개의 세그먼트를 시공하는 세그먼트시공공정(S4)으로 이루어지고, 상기 세그먼트시공공정(S4)은, 상기 세그먼트가 연결되는 세그먼트이랙터를 회전시키는 것에 의해 상기 세그먼트가 회전되어 복수개의 세그먼트가 서로 겹쳐지지 않고 서로 측면이 밀착되어 조립설치되도록 이루어진다.
