Abstract: Apparatus for planting green plants on reinforced concrete structures includes a T-shaped base mount having a positioning hole connected to an L-shaped tube and a high density sponge inside. The base mount is connected to a cylinder which includes a positioning hole connected to a T-shaped tube. A sand-releasing tube is connected at the bottom of the T-shaped tube and a funnel-connected snake-shaped tube is connected at the top. Another positioning hole on the cylinder is connected to an L-shaped air pipe. A cover plate having a hole at the center is attached to the top of the cylinder, the hole in the cover plate being connectable to a planting tube. The cylinder is connected to an anchor-shaped metal handle and a cylinder fixing frame so as to position the entire apparatus on steel rods within the reinforced concrete structure.

Abstract: An automatic water supply device comprises a pot-shaped case having a space enclosing a flowerpot in the inside, a supporting bed of reverse bowl shape enclosed in the case and holding the flowerpot thereon, a control unit arranged in a gap between the inside of the case and the flowerpot and containing at least an air pump, a controller and a timer, an air tube connected to outlet side of the air pump and having a front end part communicating with the inside of the supporting bed, and a device to exhaust air in the supporting bed when the supplying water is finished. Since the water supplying device basically has simple structure that a supporting bed of reverse bowl shape is inserted from the upper side and enclosed in the case, a part storing water can be taken to pieces and inspection or cleaning is easy.
