PURPOSE: A pipe loop type reinforcing ring of wastewater processing equipment is provided to easily repair the wastewater processing equipment. CONSTITUTION: A pipe loop type reinforcing ring(1) of wastewater processing equipment satisfies a formula 3, fc/1518+fb/1584<=1. The reinforcing ring satisfies a formula 4, Per=2(E'EI/r^3)c^1/2>=2P. The formula 3 relates to the stability, and the formula 4 relates to buckling load. In the formula 3, fc represents the pressure stress of a pipe, and the fb represents the bending stress of the pipe. In the formula 4, E' represents the elasticity modulus of the ground and E represents the elasticity modulus of a steel material. I represents the cross section secondary moment of a circular steel pipe reinforcing ring, and P represents the load per unit width. |
