Abstract:
Apparatus to install structural supports in a mine tunnel. The apparatus is conveniently mountable on a mining machine having a cutting head (105) mounted at one end of a boom. An extendable and slewing manipulator arm (110) is mounted on a support platform that is slidable in the axial forward and rearward direction and comprises a grasping device to hold the structural supports (111) in a plurality of different positions.
Abstract:
The present invention relates to a rib for supporting and reinforcing an excavation. The invention also relates to a structure and to a method for supporting and reinforcing an excavation. The rib according to the invention comprises at least a structural element provided with a tubular body, preferably with a circular cross section, which defines an inner cavity adapted to be completely filled with concrete after installation of the rib. The structural element is provided with a filling device operatively couplable to concrete injection means.
Abstract:
An underground roadway support comprises interconnected side-by-side arch sections (20, 21, 22) each constituted by a plurality of interconnected panels (23, 24, 25). Each panel comprises a plurality of arch sections butted and coupled together, the panel being of rectangular configuration and having on two opposed sides formations adapted movably or adjustably to engage complementary formations on corresponding panels of adjacent arch sections to provide mechanically flexible connections therebetween. The formation on one side of a panel is a channel (31) open outwards of the panel, while the formation on the other side of the same channel is a box section (32) adapted to engage within a channel formation of an adjacent panel to form, in effect, a knuckle joint thus to permit joined panels, and consequently joined arch sections, to accommodate earth strata irregularities or variations.
Abstract:
A robotic drilling system for creating tunnels and conduits is disclosed. The robotic drilling system can include a drill module, a frame module, and/or a shuttle module. The drill module can include a drill and is used to drill into a material to create a void that is the volume of an uncompressed frame module. Frame modules can support the sides of a conduit created by the drill module. Frame modules can be inserted into a conduit in a compressed state and are moved through uncompressed frame modules into a void. A frame module can then be expanded into an uncompressed state that supports the walls of the void. In many embodiments, a shuttle module is used to move the frame modules into position. The shuttle module can also be used to remove shredded material created by drilling by the drill module.

본 발명은 길이조정이 가능한 강관 지보재와 이를 충진ㆍ강성이 강화된 CFT 강관 지보재에 의해 강지보공의 2원화 설치시스템에 관한 것으로 천정 크라운(Crown)(C)의 수평길이 확장부(L)에서 수평길이 조정관(P)에 의해 아치형상부 반단면 강관 지보재의 수평 길이가 확장ㆍ조정되도록 함으로써 과굴이 발생된 터널 지반과, 그리고 과굴 쪽으로 수평 이동된 아치형상부 반단면 강관 지보재와의 사이간격이 최소화되도록 함에 주된 목적이 있고, 수평 길이의 확장ㆍ조정에 의해 아치형상부 반단면 강관 지보재가 터널지반 쪽으로 수평 이동됨으로써 지반과 아치형상부 반단면 강관 지보재의 과굴 간격이 최소화될 뿐만 아니라 여기에 타설될 고가의 숏크리트 양도 최소화되어 경제적인 터널시공이 되는 유용한 발명이다.
Abstract:
A rib for supporting and consolidating an excavation comprises at least a first structural element (5A) and at least one connection element (10) for connecting the said structural element (5A) of the said rib to a corresponding connection element (10') of an adjacent rib (1'), the said connection element (10) being capable of engaging through translatory motion with the said corresponding connection element (10') of the adjacent rib.

Abstract:
A support arrangement for a tunnel Including a plurality of spaced arches, each having a curved overhead section, interconnected to each other by means of bracing structures, which are supported on two respective legs which are each engaged with yielding ground-engaging supports.
Abstract:
터널 시공시 사용되는 강지보재를 콘크리트 충전강관(CFT) 구조로 형성하여 터널 굴착면에 설치함으로써 기존의 격자지보재에 비해 강성을 높일 수 있고, 가벼운 중량으로 인해 터널 막장에서 시공성을 향상시킬 수 있으며, 또한, 터널 굴착면과 콘크리트 충전강관 후면부 공간에 숏크리트를 타설할 때 리바운드량을 감소시킬 수 있고, 공간 미충전 가능성을 매우 낮출 수 있으며, 또한, 공동을 발생하지 않기 때문에 콘크리트 충전강관과 숏크리트를 완벽하게 일체화시킬 수 있다.
