It is configured to support the lower side of the cover member 30 to be.

The guide bar 23 is provided with a fixing protrusion 230, and the fixing protrusion 230 is extended in the longitudinal direction in the center of one side of the guide bar 23, and the cover is assembled to the front of the fixing block 20. The member 30 was prevented from spontaneously leaving and flowing left and right.

As shown in FIGS. 3 and 4, the cover member 30 is coupled to the front of the fixing block 30 to neatly fix the cables 40, and the body 31 has a rectangular enclosure shape with the front surface open. It is formed to accommodate the cable gripping member 50 for holding the cables 40 on the inside thereof, and on both sides, guide grooves 32 corresponding to the fixing protrusions 230 of the guide bar 23 are provided in the longitudinal direction. It is formed long to couple the fixing protrusion 230 of the guide bar 23 to the guide groove 32.

In addition, on both side surfaces of the receiving portion 33 in which the cable holding member 50 is accommodated, a cable holding groove 34 is formed in the horizontal direction and long in the horizontal direction, the front portion of which is opened so that the cable 40 can enter and exit, and the cable holding groove ( 34) is provided with assembling parts 35, 36 and support protrusions 37 formed of long holes drilled long in the longitudinal direction and holes through which shaft rods pass so as to assemble the cable gripping member 50, In a state where the cable holding member 50 is placed on the support protrusion 37, it is fixed via shaft rods 56 and 57 coupled to the respective assembly parts 35 and 36.

5 is an exploded perspective view in a state in which the cable holding member is separated in the cable conduit installation system of the underground transmission line according to the present invention.

The cable holding member 50 is composed of a case 51, an elastic body 53 that retains the elasticity of the spring 52, and a rotating roller 55 made of a rubber material such as urethane.

The case 51 is connected to the inner accommodating part 33 of the cover member 30 through the hole 510 formed on both side portions and the shaft rod 56 coupled to the assembly part 36 of the cover member 30. To be assembled, the elastic body 53 is fixed by welding a plurality of springs 52 at regular intervals between the upper plate 531 having the fastening hole 531a and the lower plate 532 having a hemispherical lower surface. It is assembled on the lower side of the case 51 through the medium of the fastening member 58 assembled by the upper plate 531 and the fastening holes 531a and 511 of the case 51, and the rotating roller 55 is a soccer ball at the center of the shaft.
