At this time, the top support 2 on the upper side is subjected to tension, and the bottom support 3 still supports the support plate 1, thereby avoiding the phenomenon of deflection of the support plate 1 inside the trench (when only one support at the center point is arranged, the increased pressure on the lower side forms a moment of rotation, which makes the support plate 1 rotate around the center support), and effectively ensures the construction safety.

[0031] The telescopic top support 2 can adapt to trenches of different widths, thereby enhancing the practicability.
