Drainage mechanism can also be arranged on the through hole or the straight joint of the some of ring beam madial wall bottom and last ring beam lateral wall bottom; The pond top ends of cans is a plane cover, or is convex surface lid low around the height of middle part, and the through hole of the madial wall bottom of last ring beam and last ring beam lateral wall bottom or the quantity of straight joint respectively are one, or are two, or are three, or are four, or are five.
The madial wall of last ring beam is greater than or equal to its lateral wall, and the madial wall of lower ring is greater than or equal to its lateral wall, and the end of the inside and outside sidewall of last ring beam and lower ring is provided with flange or does not establish flange.
The junction of lower ring and cylinder pond tank skin scribbles sealant layer, the junction of lower ring and pond top ends of cans scribbles sealant layer, the junction of last ring beam and pond top ends of cans scribbles sealant layer, the material of cylinder pond tank skin, pond top ends of cans, lower ring and last ring beam is a steel plate, or stainless steel sheet, or glass-felt plastic, or engineering plastics.
The beneficial effects of the utility model:
1, the utility model comes connection pool top ends of cans and pond jar by last ring beam and lower ring, this version not only makes tank body be easy to sealing, and attachment security is reliable, when whole pond tank body bears positive and negative pressure, can guarantee that the hermetically-sealed construction of pond tank body is not destroyed.
2, the cross section of lower ring in the utility model and last ring beam is approximate inverted U-shaped and approximate U-shaped, the weight capacity of this structure is stronger, can reach the weighted design requirement even adopt thin material to make also, therefore can make whole pond tank body simple in structure, deadweight is little, cost is low, easy construction.
3, the drainage mechanism in the utility model can make the ponding on the top ends of cans of pond drain rapidly, and what prevented that ponding from causing gets rusty, presses problems such as the pond top ends of cans that collapses.
