<p>The present invention is intended to protect conduits buried underground for electricity and communication cables and also for gas and water supplies and the like that are buried underground, and relates to a functional underground conduit multi-protector wherein multi-protectors are provided that are made of reinforced-concrete-block structural elements having reinforcing bars placed on the insides thereof, and these multi-protectors are laid coupled together along underground conduits for electricity and communication cables and also for gas and water supplies and the like, with a predetermined space kept open at the upper part of the conduit such that it is possible to readily detect construction channels and underground conduits in the buried state, and damage is minimised even if a bucket does strike during excavation work and so damage to the underground conduit is prevented, and, when the multi-protector sustains an impact from the outside during work, a capsule that emits colour and smell is burst such that the driver of the excavator can be easily and stably alerted to the fact that they are in an area where an underground conduit is buried, and also multi-protectors can easily be laid coupled together regardless of the number of underground conduits and thus the efficiency can be improved all the more. The present invention also relates to a method for constructing a conduit buried underground using the multi-protector.</p> |
