In addition, although not shown in the drawing, the tipping tube with a pinch valve for the front end (1) and the intermediate placement tube (2) are also provided in the same manner as the rear end bend tube (3). Threaded portions (1 ′) and (2 ′) are respectively provided on the outer periphery of the water shielding material dropping prevention pin insertion portion, and the cap portions (1b), (1b), (2b) (2b) is provided so that it can be screwed into six places. Further, the cap for embedding is used when filling with a water shielding material.

    FIG. 5 (A) is a plan view of the rear end bend pipe (3) when the water shielding material fall prevention pin (3c) is inserted, and FIG. 5 (B) is a partially cutaway side view. In addition, although not shown in the drawing, a water blocking material is also provided for the leading pipe with a pinch valve (1) and the intermediate pipe (2) in the same manner as the rear end bending pipe (3). Drop prevention pins (1c) and (2c) are provided. Further, this water shielding material fall prevention pin is for preventing the water shielding material in the pipe from dropping due to its own weight when the placing pipe is cut off.

    Next, FIG. 6 shows an example of a procedure for placing the soil impermeable material, and when the water shielding material is placed, a hanging tool (WR) such as a wire rope is used to suspend the placing pipe. In the excavation hole (H), each connection flange of one driving pipe (1) with a pinch valve (PV) for a tip having a diameter of 100 mm and a total length of about 5 m and a plurality of (5) intermediate driving pipes The parts are fastened with locking members such as bolts (B), nuts (N), and washers (W), and inserted while being connected. Finally, at the time of fastening, each time the fastening is performed, fastening work is performed while laying stopper plates (5) for preventing dropping at both ends of the connection flange, and the placing pipe is extended. Then, when the operation of inserting the placement pipe is completed, the operation continues to the placement work of the soil impermeable material.

    Then, the soil impervious material is placed by pulling it slowly while lifting the entire device with a wire rope or other hoisting tool (WR) provided at the end while filling the impermeable material. When the lower flange (2a) of the intermediate placing pipe (2) arrives, a stopper plate (5) for preventing the fall is laid on the lower surface of the connection flange of the second intermediate placing pipe (2). In addition, three water-blocking material fall prevention pins for the intermediate placing pipe (2) are inserted in each case to prevent the water-shielding material from falling, and to the rear end bend pipe (3). The connected first intermediate placement pipe (2) is lowered to the ground as it is, and the rear end bend pipe (3) and the first intermediate placement pipe (2) are separated. Then, the rear end bend pipe (3) separated again is lifted by a lifting tool (WR) and connected to the second intermediate placement pipe (2) fixed temporarily. While repeating such a series of operations, the driving tube is pulled out one by one in order from the rear end portion, and the driving tube is completed when the driving tube (1) with the pinch valve (PV) for leading end is pulled out. The point of this work is that when the casting tube is cut off, the water shielding material falls due to its own weight. Therefore, before cutting the casting tube, remove the caps for 6 plugs each time, and The water shielding material fall prevention pins (3c), (3c) and (3c) are respectively inserted to prevent the water shielding material from falling. Therefore, even if the placement pipe is separated, the water shielding material does not fall, and the work can be performed safely and efficiently.

    According to the soil impervious material placing device and the placing method of the present invention, the placing pipe is divided, and each connecting pipe is provided with a water shielding material fall prevention device for safety, workability and maintainability.・ Because it is excellent in economic efficiency, it has industrial applicability in terms of contributing to many civil engineering-related markets by manufacturing and selling.
