Resting platform for immersed tube manhole well
The invention relates to the technical field of immersed tube tunnel construction, and provides a resting platform for an immersed tube manhole well. The resting platform comprises a platform plate and a support rod, wherein the bottom end of the platform plate is connected onto the wall of the manhole well through a first hinge support; the bottom end of the platform plate is hinged to the first hinge support; a sliding groove is formed in the platform plate in the radial direction of rotation; the bottom end of the support rod is connected onto the wall of the manhole well through a second hinge support; the second hinge support is positioned below the first hinge support; the bottom end of the support rod is hinged to the second hinge support; the top end of the support rod is connected with the sliding groove in a sliding manner; when the top end of the support rod slides to the top end of the sliding groove, the platform plate is positioned at the unfolding state; when the top end of the support rod slides to the bottom end of the sliding groove, the platform plate is positioned at the folding state. According to the invention, when in use, the platform plate of the resting platform can be unfolded for constructers to rest; when not in use, the platform plate can be folded so as to ensure that the constructors passes through the manhole well smoothly, and the resting platform is convenient to use and detach, and can be used repeatedly.
