[0032] In order to further explain the technical solutions of the present invention, specific examples are given below to illustrate in detail.
[0033] A novel limit external pressure testing device for a concrete hemispherical shell of the present invention, when in use, usually the top of the arc faces upwards, such as Figure 1-3 As shown, it includes a fixed support cover 1, a capsule 2, a pressurizing device 3, a deformation detection device 4 and a data acquisition and processing device (not shown in the figure).
[0034]The fixed support cover 1 is set outside the concrete hemispherical shell 6 and there is a gap between the inner surface and the outer surface of the concrete hemispherical shell 6. The capsule 2 is arranged in the gap in the form of expansion, and the pressurizing device 3 pressurizes the capsule 2 To make it expand, the deformation detection device 4 is arranged on the concrete hemispherical shell 6 to detect the deformation of the concrete hemispheri...
