The arc length of the outer surface of every piece of voussoir of block is：The arc length of i cylinder voussoir and housing upper chamber Cylindrical Surfaces Contact part it
And plus radial clearance between i voussoir circumferential arc length equal to the upper chamber face of cylinder circumference, i.e.,Wherein D is the diameter on the housing upper chamber face of cylinder, and L is the upper chamber face of cylinder
Circumference, L1KIt is the upper chamber face of cylinder arc length corresponding with K block voussoirs, L4KIt is the arc length of K block voussoirs, lCIt is wedge
The circumferential arc length of radial clearance, K=1,2 ..., i between block；The length of side of the outer surface of every piece of voussoir of the prism voussoir is：I
Prism voussoir contact with housing upper chamber n prism inner surfacies part length sum plus radial clearance between i voussoir
Circumferential distance is equal to the polygon length sum that upper chamber n prism inner surface is formed, that is, polygonal girth, i.e.,Wherein M be housing upper chamber n prisms inner surface formed polygonal girth, M1K
It is the upper chamber n prismatic surface length of side corresponding with K block voussoirs, M4KThe length of side of K block voussoirs, C be between voussoir radially between
The circumferential distance of gap, K=1,2 ..., i.
