A method of advancing a plurality of longitudinally arranged movable constructional units forwardly successively in a self-running manner, wherein a plurality of prefabricated constructional units for construction of an underground structure of a form adapted for a special purpose such as tunnel excavation, heavy load transportation, underwater tunnel installation or muddy water dredging excavation are arranged along a common longitudinal line adjacent to each other and are provided with a forward advancement impelling mechanism, said mechanism comprising propulsion means positioned between the successive constructional units, a linking member extending over the entire length of the combined constructional units, impelling means and anchoring means arranged at respective certain locations on said linking member, and further with the necessary engineering facilities according to the employed purpose for construction, said method comprising actuating the first propulsion means to advance the forwardmost constructional unit through the length of one stroke, releasing the first propulsion means, actuating the other propulsion means successively to advance the intermediate and tailing constructional units successively each through the length of one stroke toward the advanced forwardmost constructional unit while utilizing the reaction forces of the other stationary constructional units which are summed up by the linking and anchoring means, and repeating such a procedure of the steps constituting one cycle a number of times until the constructional units arrive at a desired site of installation. An apparatus for performing the above-described advancing method comprising propulsion means positioned between the said successive constructional units, a linking member serving the advancement of said units and arranged to pass from the forwardmost to the tailing constructional unit therethrough, anchoring members mounted at respective certain location of said linking member, and a set of equipments necessary for the supplemental engineering purpose.
A method of advancing a plurality of longitudinally aligned movable constructional units successively in a self-running manner, wherein said constructional units constituting an underground structure of a form adapted for a special purpose such as tunnel excavation, heavy load transportation, underwater tunnel construction or muddy water dredging excavation are arranged along a common longitudinal line adjacent to each other and are provided with a self-run forward advancement impelling mechanism, said mechanism comprising propulsion means each positioned between adjacent said constructional units, a linking member extending over the entire length of said constructional unit group, traction means positioned in front of the forwardmost constructional unit for forward advancement thereof and connected to said linking member, and anchorage members arranged for selective contact with the respective intermediate and tailing ones of said constructional units and mounted on and selectively engageable with said linking member, said method comprising actuating the first one of said propulsion means positioned between the forwardmost and next ones of said constructional units while releasing said traction means and all the said anchorage members from engagement with said linking member to advance said forwardmost constructional unit relative to said next constructional unit and to the ground, releasing said first propulsion means, bracing said linking member to said next constructional unit through the one of said anchorage members arranged for selective engagement therewith, actuating said traction means and the second one of said propulsion means positioned between the second and third ones of said constructional units counting from the front to advance said next constructional unit relative to the ground, advancing the other ones of said intermediate constructional units individually subsequently in a manner similar to that described above relative to the ground, bracing said linking member to said tailing constructional unit through the one of said anchorage members arranged for selective contact therewith, actuating said traction means to advance said tailing constructional unit relative to the ground through said linking member, and repeating the procedure consisting of the above-described steps a necessary number of times.
An apparatus for advancing a plurality of movable constructional units for construction of an underground structure forwardly successively in a self-running manner comprising a plurality of movable underground constructional units arranged longitudinally in one direction, an advancement linking member passing therethrough, an advancement traction device for said linking member mounted at the front surface of the forwardmost constructional unit, anchoring members selectively engageable with said advancement linking member and with the respective intermediate and tailing constructional units, and propulsion means positioned between the adjacent constructional units.
A method of advancing a plurality of longitudinally aligned movable constructional units successively in a self-running manner, wherein said constructional units constituting an underground structure of a form adapted for a special purpose such as tunnel excavation, heavy load transportation, underwater tunnel construction or muddy water dredging excavation are arranged along a common longitudinal line adjacent to each other and are provided with a self-run forward advancement impelling mechanism, said mechanism comprising propulsion means each positioned between adjacent said constructional units, a linking member extending over the entire length of said constructional unit group, traction means connected to said linking member, and anchorage members arranged for selective contact with said constructional units and mounted on and selectively engageable with said linking member, wherein the method comprises the steps of actuating the first one of said propulsion means positioned between the forwardmost and the next one of said constructional units while releasing said anchorage members for advancing said forwardmost constructional unit relative to said next constructional unit and to the ground, releasing said first propulsion means, bracing said linking member to said constructional unit by means of the respective anchoring member, actuating the second one of said propulsion means positioned between the second and third ones of said constructional units counting from the forwardmost one thereof for advancing the second constructional unit relative to the ground, and advancing the remaining ones of said constructional units individually subsequently in a manner similar to that described above relative to the ground, and repeating the procedure consisting of the above-described steps the number of times necessary for effecting the desired longitudinal movement of the constructional units.
An apparatus for advancing a plurality of movable constructional units for construction of an underground structure forwardly successively in a self-running manner comprising a plurality of movable underground constructional units arranged serially longitudinally in one direction, an advancement linking member passing through said constructional units, an advancement traction device associated with said linking member and mounted thereon at one end of said linking member, anchoring members mounted on and selectively engageable with said linking member and arranged to engage at least certain ones of said constructional units, and propulsion means positioned between adjacent said constructional units.
