摘要： PROBLEM TO BE SOLVED: To improve the modification degree of excavation soil to modified soil by furnishing in a shield excavator a plurality of liquid additive spouting nozzles for spouting excavation soil modification liquid additives to the ground to be excavated, and additive feeding means for force-feeding additives. SOLUTION: The cutter spoke members 3 include a plurality of spokes 20 fixed to a rotating shaft 13 and extending to the outer peripheral side therefrom, and nozzles 5, 6 for spouting additives to the excavated ground G are fixed to two spokes 25, 26. The spouting nozzle 5 is arranged near the outer periphery of the spoke 25, and the spouting nozzle 26 is also arranged near the longitudinally directional center of the nozzle 26. The two nozzles 5, 6 rotate along with the cutter spoke member 3, and pressures effecting both the nozzles 5, 6 are different depending on the position of the spouting nozzles 5, 6, however, by providing independent two pumps 31, 32 on both the nozzles 5, 6 respectively, additives can be spouted positively.

摘要： PURPOSE:To produce a heat transfer joint with flexibility and excellent heat-conductive properties, and to facilitate the quality control of the same, by a method wherein a heat transfer member prepared by twisting multiple element wires is provided with a binding terminal which is radially crushed to bind the heat transfer member, and both end surfaces of the bound terminal are flushed, and then a heat transfer piece thus formed is brazed to a flange. CONSTITUTION:First flexible twisted wires made by twisting extra fine element wires are twisted and bound to form second flexible twisted wires 36, and an annular-type bound terminal 38 made of metal is mounted on the flexible twisted wires 36 so as to radially cover both ends 37a of a heat transfer member 37. After the bound terminal 38 is mounted, the heat transfer member 37 is bound by crushing the bound terminal 38 from the external side. The heat transfer member 37 and both end surfaces 33a of the bound terminal 38 are machined and flushed by, for example, a lathe, a milling machine or the like to form a heat transfer piece 33. These pieces are arranged in a state that twelve of them are arrayed in a circumferential shape, and both end surfaces 33a of each of them are brazed and bonded to a pair of flanges 31 and 32 by using a brazing material such as low-temperature solder with high strength and thermal conductivity at a low temperature, thereby forming a heat transfer joint 30.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a lip is abraded by soil and sand penetrated into a seal and the durability of a sealing material is deteriorated in a sliding section having a large sliding stroke, quick sliding speed and further a large number of reciprocation numbers. SOLUTION: A shield body 1 is composed of a double-drum structure with a front drum 2 and a rear drum 3, the sliding section 4 is installed between the front drum 2 and the rear drum 3, and the sliding seal 9 sealing a section between the front drum 2 and the rear drum 3 in the case of a sliding and the dust seal 17 sealing the front drum 2 and the rear drum 3 at the rear end of the front drum 2 are mounted on the sliding section 4. The shield body is constituted so that an opening 22 between the front drum 2 and the rear drum 3 sealed with the sliding seal 9 and the dust seal 17 is supplied with washing water 25 at a fixed pressure, and the durability of the seals is improved by preventing the penetration of soil and sand to the sliding seal 9 and the consolidation and fixing of soil and sand at an outer-circumferential stepped section at the rear end of the sliding section 4.
