A rainwater receiving apparatus installed to the foundation of a power transmission tower is provided to collect rainwater running along a foundation concrete and drain the rainwater through drain pipes and connection pipes. A rainwater receiving apparatus installed to the foundation of a power transmission tower comprises first and second frames(10,20), first and second fastening units(30,40), and a support. Each frames includes a bottom plate(101,201), an outer part(102,202), and an inner part(103,203). The outer part, which is integrally formed with the bottom plate, has a flange(102a,202a) with bolt holes(102a',202a') and a drain pipe(102b, 202b) with a wrinkled portion(102b',202b'). The inner part is connected to the bottom plate in opposition to the outer part with the same height as the outer part. The inner part includes a protrusion(103a,203a), a fitting portion(103b,203b), and a flange(103c,203c) with bolt holes(103c',203c'). The protrusion extends upwards from the top of the inner part. The fitting portion is normal to the protrusion and protrudes toward the foundation concrete. Each fastening units includes a lower plate(302) and an upper plate(301). Each lower plate has an insertion groove(301a,401a) to which the fitting portion of the first and second frames. The upper plate is normal to the lower plate and provided with a packing rubber(32) attached to the inner peripheral surface. The upper plate is further provided with a wing portion(302a) having bolt holes(302a'). The support is installed to support a connection pipe connected to the drain pipe. The support includes a fastening unit, a support unit, and an insertion unit. The fastening unit wraps around the connection pipe and is tightened by a bolt. The support unit is located under the fastening unit. The insertion unit is buried under the ground. |
