る。 FIG. 1 is a longitudinal sectional front view of the irregularly shaped porous tube 1. FIG. The irregularly shaped perforated tube 1 shown in this figure has an outer tube 2 made of cast iron.
A filler material 3 is placed inside. One end 2a of the outer tube 2 has a circular cross section (see FIG. 2), and the other end 2b has a rectangular cross section larger than the one end 2a (see FIG. 3). The filler 3 also includes an outer tube 2 in the axial direction between the circular end surface 3a and the rectangular end surface 3b.
A multi-striped hole 4 is formed diagonally through the tapered body 2c. The position of the multi-striped hole 4 on each end surface 3a, 3b is determined by the perforated pipe 5 and the U-shaped groove 6.
It is set to correspond to the cable laying position inside the Further, a chamfered portion 8 is formed at the open end of the multi-strip hole 4 so that a cable can be easily inserted into the multi-strip hole 4. As the filler 3, concrete or the like can be used if the purpose is to reduce the cost, and urethane foam or the like can be used if the purpose is to reduce the weight.
