    • PROBLEM TO BE SOLVED: To provide a passing-through device for a clogged pipe capable of greatly promoting the elimination work of foreign matters by providing strong water pressure variations in piping and being easily and surely mounted to the piping. SOLUTION: A passing-through device 1 is so constituted that an introduced pipe 4 is mounted to the front end of a cylindrical body 2 by a joint pipe 3. A piston faucet 6 capable of making reciprocating motion is provided in the inside of the cylindrical body 2 by a control rod 5. A cylindrical faucet 7 of an elastic body is mounted to the front end of the introduced pipe 4. When the piston faucet 6 is approached to the water surface in the cylindrical body 2, an inside passage of the piston faucet 6 is opened to exhaust air to the upper side from the lower side and, at the same time, an opening and closing valve for cutting off the inside passage is provided in the piston faucet 6 in the case of reciprocating motion of the piston faucet 6. When foreign matters in a drain pipe are eliminated, the cylindrical faucet 7 is expanded by an air injection pipe 8 to close a gap between the drain pipe and the introduced pipe 4, and the reciprocating motion of the piston faucet 6 is made to provide water pressure variations in the drain pipe.

    • PROBLEM TO BE SOLVED: To accurately and firmly fix a piping, a tank, and an apparatus on a frame, formed of an angle and a channel, through a simple work and besides to perform high reliable fixing work without lowering the strength of the frame. SOLUTION: A fixing auxiliary tool 10 comprises a vertical plate part l5, a horizontal plate part 16, a lock part 17, a lock plate part 18, and a support part 19. A bed plate 11a and a rib plate 11b are formed at an angle 11. When a piping P is fixed at the angle 11, the piping P is placed on the bed plate 11a, the lock part 17 is then fitted in the lower end of the rib plate 11b, and the vertical plate part 15 and the horizontal plate part 16 are brought into contact with the rib plate 11b and the bed plate 11a. The lock plate 18 is arranged in a manner to extend to the front of the bed surface of the bed plate 11a. A U-bolt then spans the piping P, the U-bolt 12 is inserted in the bolt hole of the lock plate part 18, and fastened by a nut 13 from the back side of the lock plate part 18.
