The invention discloses a temporary isolation plugging device for
tunnel construction and a using method thereof. The temporary isolation plugging device comprises a vehicle body, wherein a
servo motor B is arranged in the middle of the bottom of the interior of the vehicle body, a threaded column is arranged at the output end of the
servo motor B, inner threaded sleeves which are matched with each other are arranged on the outer side of the threaded column, and hinge seats are arranged on the two sides of the inner threaded sleeves. According to the temporary isolation plugging device for
tunnel construction and the using method thereof, arc-shaped supporting plates are formed through mutual unfolding of arc-shaped outer sleeves and arc-shaped inner sleeves, arc beams of tunnel entrances with different sizes are attached, and the attaching performance and the buffering function of the arc beams of the tunnel entrances are further improved by utilizing mutual linkage of attaching
layers, arc-shaped rubber elastic pads, guide sleeves, springs and buffering structures applied by sleeve columns, so that vibration generated by
tunnel construction is reduced; and when a tunnel collapses under the support of the structure, a reinforcing
system can be formed by utilizing attaching support of the device and the tunnel entrances, so that the assembling structure of the tunnel arc beams can be stored.
