Sealing steel reinforcement cage used for sealing diversion tunnel through cast-in-plate reinforced concrete without gate for setting off

The utility model discloses a sealing steel reinforcement cage used for sealing a diversion tunnel through cast-in-plate reinforced concrete without a gate for setting off. The sealing steel reinforcement cage used for sealing the diversion tunnel through the cast-in-plate reinforced concrete without the gate for setting off is characterized in that a work procedure of gating the diversion tunnel can be eliminated, concrete work amount of the gate can be reduced, and concrete sealing can be carried out when the diversion tunnel divides flow normally. A plurality of water discharging pipes are fixed on the sealing steel reinforcement cage, the cross section area of a plurality of combined sealing steel reinforcement cages is the cross section area of the diversion tunnel, the sealing steel reinforcement cages are put into the diversion tunnel in sequence, or the diversion tunnel is divided into a plurality of areas, net-shaped steel bar frames with the water discharging pipes are respectively erected in the areas, and concrete is poured in the areas in sequence. When the strength of the concrete meets the design requirements, gate valves of the water discharging pipes are closed, sealing concrete is normally poured at the back of the gate valves, and the gate valves are buried into the concrete.
