    • PROBLEM TO BE SOLVED: To safely and easily perform an opening/closing operation of a heavy subsidiary lid of a manhole by oneself.
      SOLUTION: This device is composed of a square main lid 1, the paired subsidiary lids 20, and a fixing bar 30 and a fall preventing stopper 40 for each of the subsidiary lids 20. In the main lid 1, a square opening 2 is formed inside it; locking edges 6 and 7 are provided so as to face each other along central parts of both lateral sides on a long side of the opening 2 and both lateral sides on a short side thereof, respectively; and guide rails 11 equipped with guide holes 10 are provided along both right and left side parts of each of the lateral sides on the long side, respectively. The subsidiary lids 20 are juxtaposed with a gap 21 between them; peripheral edges of them are formed so as to be large enough to be placed on the locking edges 6 and 7; and a rotating shaft 25 is provided in approximately central parts on both lateral sides of each of the subsidiary lids 20, so that a roller 26 can be attached to the rotating shaft 25 and mounted so as to be movable on the guide rails 11. The fixing bar 30 is inserted into the gap 21 between the subsidiary lids 20, so that both ends thereof can be detachably attached to a central part on the long side of the main lid 1. In the stopper 40, bearing fittings 43 and 46 are provided in appropriate places on each of the backsides of the main lid 1 and the subsidiary lids 20, respectively, and both ends of a supporting rod 41 are attached to both of the bearing fittings 43 and 46.

    • PROBLEM TO BE SOLVED: To enable a hot spring pipe to be easily laid in the ground along a road or the like by utilizing a trough, and at the same time, to provide a hot spring piping device by which maintenance and management of the hot spring pipe is very easy and which can prevent piping damages or the like from occurring. SOLUTION: The piping device has the following composition. The piping device is for guiding the hot spring pipe 20 to utilizing facilities. A required number of troughs 1 are connected and embedded along the road or the like. And at the same time, the upper face of its lid body 3 is made approximately the same as the ground surface. The hot spring pipe is laid inside the trough body 2. The trough body 2 is formed into a cross-sectional U-shape. Locking step parts 11, 11, to which both end parts of the lid body 3 are fitted, are respectively provided at the upper end parts of both side walls 9, 9 of the trough body 2. And at the same time, circular thin-walled parts 10, 10 are provided at appropriate places on both side walls so as to be capable of forming a pipe hole 26 of a branch pipe. Also, the hot spring pipe 20 is laid on pipe receiving members 13, 41 provided at the bottom part of the trough body 2 and it is fixed to the pipe receiving members by a fixing band 31.
