<P>PROBLEM TO BE SOLVED: To provide drainage equipment that allows a catch basin and a cable pit to be disposed in a side-ditch block for water drainage that also functions as a common ditch for electric wires, at an appropriate position where cables are easily laid. <P>SOLUTION: Drainage equipment comprises a plurality of side-ditch blocks 1, each having a water drainage space 17 at an upper half of the section thereof and a storage space 18 for cables 5 at a lower half of the section thereof. The drainage equipment comprises: a side-ditch section 3 composed of side-ditch blocks 1 serially buried in the longitudinal direction of a road 2; and a single or a plurality of change blocks 31 connected to the side-ditch block so as to be positioned at an extension of the side-ditch section 3. The change block 31 comprises: an upper space 37 that communicates with the drainage space 17 and changes its drainage direction to the side of the center of the road; and a lower space 38 that communicates with the storage space 18 and allows the cables 5 to pass therethrough without being bended. <P>COPYRIGHT: (C)2012,JPO&INPIT |
