<p>PURPOSE:To enable offset design of a cable freely in taking advantage of the space of a manhole effectively, by fixing pressurizedly the cable laid along inside the conduit line radially by means of a pressurizing mechanism, etc., in the conduit line. CONSTITUTION:A cable receiver 10 is inserted under a cable 2 and put it fixedly onto the inner wall of a conduit line 1. To a curved recessed surface 10a the cable 2 is anchored. A pressurizing mechanism 11 is then inserted into the conduit line 1 at its upper part and arranged in position. A pressurizing member 19B is placed face to face to the cable receiver member 10 and anchored onto the circumferential surface of the cable 2. A twisting bar 12 is then operated to pivot and by approaching both moving blocks 13 and 14, the pressurizing member 19A is caused to press the inner wall above the conduit line 1 in the radial direction of the conduit line 1 so that the pressurizing member 19B will press the upper surface of the cable 2 to the radial direction of the conduit line 1. In this way, the cable 2 is pressed radially inside the conduit line 1 and can be fixed. No cable section is therefore required to be fixed with cleat, etc., inside the manhole.</p> |
