摘要： PROBLEM TO BE SOLVED: To provide a snow cold heat accumulative tank in which some impurities kept in snow can be easily removed and transported out of the tank even if the impurities are adhered to the bottom surface of the tank and accumulated there, resulting in that a heat exchanging system can be always worked effectively. SOLUTION: A bottom surface in a tank is provided with several groove-like water passages 2 and a mud-storing groove 3. Each of the water passages has a cleaning water dispersion port cooperatively related to a water dispersion system, respectively, so as to enable some impurities stacked in the water passages to be pushed and flowed. The mud-storing groove 3 is constituted such that one end segment of each of the water passages is placed near it to enable the cleaning water from the water passages to be accumulated, and the mud accumulated there is removed.

摘要： PROBLEM TO BE SOLVED: To provide a plate for a steel shell joint for use in an outer shell antecedently constructed tunneling method which dispenses with loosening of the plate after fastening of the same. SOLUTION: There is provided a plate for a steel shell joint for use in an outer shell antecedently constructed tunneling method, which is connected to a coupling portion of a steel shell adjacent to the steel shell concerned, in order to couple the adjacent steel shells each forming a unit tunnel, via a hemispherical washers, joint bolts, and nuts, to each other. To this end, the plate has a plurality of concave hemispherical washer bearers and a plurality of frusto- conical bolt holes each having a small diameter on the washer bearer side and opens on the bottom of the washer bearer. In this plate, the hardness of the washer bearer is made different from the hardness of the washer.

摘要： PROBLEM TO BE SOLVED: To provide a coupling joint for single shields forming the outer shells of a large-cross-section tunnel, and a coupling method. SOLUTION: A friction coupling bolts the main girders of steel shells 1 together by means of connecting steel 3 and added plates 4, the steel shells 1 constituting adjacent single shields K. The added plate 4 used is previously curved to an angle corresponding to the deviation of the main girders 2 of the steel shells 1 of the adjacent single shields K from one to another. The added plates 4 are joined to the main girders 2 of the steel shells 1 by high- strength bolts 6, and the added plates 4 and the connecting steel 3 are joined together by the high-strength bolts 6.

摘要： PROBLEM TO BE SOLVED: To provide a joint structure or the like of a superior adaptability and workability by joining the steel shell main girder of each adjacent single body shield simply directly, and making an appropriate correspondence between each single shield even if an execution difference occurs between them. SOLUTION: In the outer shell preceding type tunnel method, the outer peripheral surface of a spherical washer 5 is formed into a freely rotatable sphere at an angle θ equivalent to a positional dislocation of the steel shell main girder 2 of each adjacent single body shield K. Then, the washer contact part of an end plate 3 is formed into a spherically-recessed receiving part for receiving an outer peripheral surface of the spherical washer 5, and a bolt hole 4 is shaped into an unfolded fan shape with an angle θ for permitting the aforementioned positional dislocation by making use of the receiving part as a base point. The spherical washer 5 is passed through a bolt hole 6 pierced through the bolt hole 4 of the end plate 3, thereby achieving its joint by the screwing a nut 7 therein.

摘要： PROBLEM TO BE SOLVED: To suppress residual stress at the time of erection by integrally constituting main girders on both sides of a steel segment through skin plates, and jointing axially adjacent rings to each other by fastening mutual webs and flanges of the main girders by bolts. SOLUTION: A steel segment for an outer fence preceding shield construction method constitutes an outer enclosure structure body of a main tunnel, and the outer enclosure structure body has a center pillar erected as a support to suppress the generation of bending moment. A joint is provided near an inflection point of positive-negative bending of bending moment acting upon the outer enclosure structure body. The steel segments 7 of adjacent rings are jointed to each other by making mutual main girders 8, 16 directly butt each other and fastening them by bolts 11 through splice plates 10. Mutual flanges 8b, 16b of the main girders 8, 16 are also fastened by bolts 11 putting two splice plates 12, 12 thereon.
