摘要： The method for boring a tunnel consists in placing an excavation tool at a point of the extrados of the tunnel and in excavating a cavity by imparting the tool an advancement movement having divergent direction with respect to the axis of the tunnel. While the cavity is being filled with concrete, a further cavity is excavated in another point of the extrados and is then also filled with concrete. These operations are repeated until a plurality of voussoirs is obtained which are arranged adjacent to one another along the extrados and give rise to a frustum-shaped vault. The soil inside the vault is then excavated for a depth which is smaller than the axial extension of the vault itself, and a subsequent vault is formed having a narrower initial portion internal to the wider terminal portion of the previously executed vault.

摘要： A drive chain for transmitting power to a rotatable cutter head of a mining machine. The mining machine is of the type having a rotary cutter drum mounted at the forward end of the mining machine frame. The cutter drum has helical auger flights with cutter bits mounted on their periphery. Electric motors are provided on either side of the mining machine to provide power for rotating the cutter drum. A drive and cutter chain transmits the power from each electric motor to the rotary drum. The drive chain comprises roller chain links with offset sidebars. Each drive chain is relatively narrow having but a single row of links. Some of the links are cutter links which carry cutter bits. Selected portions of the cutter links and the sprockets are cut away to prevent entrapment and build up of foreign matter.
