The utility model discloses a water conveyance canal ice discharging gate structure which comprises an ice discharging groove, the inner walls of the two sides of the ice discharging groove are jointly and fixedly connected with a gate seat, one side of the outer surface of the gate seat is connected with a gate in an abutting mode, the gate is rotationally connected with the ice discharging groove, and an inclination angle assembly is jointly installed between the gate and the ice discharging groove. The top of the ice discharging groove is fixedly connected with a support. According to the utility model, through the arrangement of the support, the synchronous driving assembly, the reciprocating screw rod, the sliding block, the sliding rod and the ice breaking assembly, floating ice which is about to enter the ice discharging groove can be alternately impacted, so that the floating ice becomes small, large floating ice is prevented from entering the ice discharging groove to cause blockage, and the ice discharging smoothness is ensured; the water outlet height is increased through the gate seat, installation of the inclination angle assembly is facilitated, the inclination angle of the gate can be adjusted according to the water level in the water conveying channel and the actual ice discharging requirement during actual ice discharging, and loss of a large amount of water in the water conveying channel is avoided.

The invention discloses an air curtain type tunnel portal water interception device which is arranged at a tunnel portal or a junction of an intersection open section and a hidden section of an urban underpass road, the water interception device comprises a plurality of vertical ventilation pipelines arranged on a central anti-collision wall, and the bottom of each vertical ventilation pipeline is connected with an air blower. The air blower is fixedly connected with the central anti-collision wall; the adjacent vertical ventilation pipelines are communicated through a plurality of transverse ventilation pipelines, air outlets are formed in the two sides of each transverse ventilation pipeline in the horizontal direction respectively, and a rotatable movable cover plate is arranged at the position, corresponding to the air outlets, of each transverse ventilation pipeline. According to the method, a transverse intercepting ditch does not need to be arranged at the tunnel portal and the junction of the open section and the hidden section of the intersection of the urban underpass, regular dredging and maintenance are not needed, the maintenance cost is reduced, the economic benefit is improved, and the driving safety and smoothness are greatly guaranteed.
