摘要： PURPOSE:To prevent effectively a heavy machine from entering a danger zone while the heavy machine is in operation without building up a barricade or placing a guiding person by separating a background video image and a video image of the heavy machine, a mobile object, and distinguishing the danger zone from a safety zone based on the background video image. CONSTITUTION:A picture processing unit 5 processes a video signal 3 from an ITV camera 1 as a digital image and separates a video image of a construction purpose heavy machine 11 such as a shovel being a mobile object from other video images. A specific zone setting entry device 8 is used to distinguish a safety zone S from a danger zone D from the video image displayed on a monitor 7. When the construction use heavy machine 11 being the mobile object intrudes into the danger zone D on the monitor 7, the picture processing unit 5 outputs a specific zone intrusion signal 4 to an alarm signal generator 9. An alarm signal generator 9 receiving the specific zone intrusion signal 4 provides an output of an alarm signal to inform the alarm to the operator and persons relevant to the heavy machine 11 for construction.

摘要： PURPOSE:To separate the prescribed subsoil in a tunnel from the surrounding subsoil and extrude the separated subsoil into one shaft by drilling the subsoil between the first and second shafts with a wire saw. CONSTITUTION:Small through-holes 1a, 1b, 1c and so forth are drilled to be continuous from the first shaft BT1 to the second shaft BT2 along the periphery of a tunnel cross section at the preset intervals. Then, a wire saw 2 is led from the first shaft BT1 to the second BT2 through the hole 1a, and returned from the second shaft BT2 for run through another hole 1b and return to the first shaft BT1, thereby forming loop state. The wire saw loop 2a so formed, while being dragged, is turned toward the first shaft BT1, thereby drilling the subsoil surrounded by the wire saw loop 2a along a direction from the second shaft BT2 to the first shaft BT1. This drilling process is undertaken all around the tunnel cross section for separating the subsoil G1 in the tunnel T from the surrounding subsoil G. Then, the subsoil G1 is extruded from the shaft BT1 to the shaft BT2, and every constant amount thereof is separated and carried to the ground.

摘要： PROBLEM TO BE SOLVED: To supply an erector efficiently with segments in a method of shield construction by a comparatively simple equipment at low cost by lifting and lowering a receiving section and moving the receiving section, which receives the segments from a mount section, on which a plurality of the segments can be mounted, and on which the segments are put, in the longitudinal direction. SOLUTION: A plurality of segments 1P-6P mounted on a base 2 (a mount section) are received from the base 2 to a rod 3 (a receiving section) by lifting devices 5 composed of hydraulic jacks 8, slides 10, slide support bases 11, etc., and mounted. The rod 3 is moved in the longitudinal direction by a shifter 6 consisting of a support base 12, a hydraulic jack 13, a support member 15, etc. Accordingly, the segments 1P-6P mounted on the base 2 from a truck, etc., can be conveyed automatically in the forward direction by the lifting device 5 and the shifter 6, and the segments temporarily positioned from the truck need not be shifted to a specified place again, and can be transported efficiently.

摘要： PROBLEM TO BE SOLVED: To facilitate the exchange of a bit in response to the soil to be excavated by providing a cutter spoke in a cutter to be freely turned over, and arranging roller bits in one surface and teeth bits in the other surface. SOLUTION: A cutter 2 of a shield excavating machine is formed of a surface plate 3 provided with teeth bits 8 and cutter spokes 4, 5. Roller bits 6 are arranged in a surface of the cutter spokes 4, 5, and teeth bits 9, 10 are arranged in the back surface thereof so that they can be turned over by a driving means. With this structure, in the case where the excavating soil is a viscous soil layer, excavation is performed by the roller bits 6 and the teeth bits 8 of the surface plate 3, and in the case where the excavating soil is a gravel layer, the cutter spokes 4, 5 are rotated and the roller bits 6 are housed inside, and excavation is performed by the teeth bits 9, 10 and the teeth bits 8 of the surface plate 3. Consequently, the bit can be easily exchanged in response to the soil conditions, and the roller bits 6 can be used in the optimal condition.
