Detailed Description
The embodiment is a flood control structure at the upstream of the top of the earth and rockfill dam, wherein a top road is arranged at the top of the dam, a wave wall is arranged at the upstream of the top of the dam, a bank road connected with the top road is arranged at the joint of the top of the dam and two banks, and a gap corresponding to the bank road is reserved between the two ends of the wave wall and the two banks.
In this embodiment, a side wall closely connected with the bank is arranged on the bank side of the gap, the side wall on one side of the gap is matched with the wave wall on the other side of the gap to form a door frame, and an openable flood gate is arranged corresponding to the door frame.
The flood gate adopts the switching form that moves a door in this embodiment, is equipped with the hidden gate slot that corresponds with flood gate removal route on dam crest highway and bank highway, is equipped with the track in the hidden gate slot, and flood gate bottom edge is located the gate slot and this flood gate bottom is through the mobilizable installation on the track of gyro wheel.
In the embodiment, a plurality of triangular buttress supports capable of supporting the flood gate are arranged on the downstream side of the flood gate, and the triangular buttress supports can be hinged on the flood gate in a horizontally rotating mode.
In the embodiment, a first water stopping structure corresponding to the bottom of the flood gate is arranged at the bottom of the door frame; the left side and the right side of the door frame are respectively provided with a second water stop structure and a third water stop structure which correspond to the left side and the right side of the flood gate. The first water stopping structure is provided with a rubber water stopping belt fixed on the bank road; the second water stopping structure is provided with a rubber water stopping belt fixed on the wave wall; the third water stopping structure is provided with a rubber water stopping belt fixed on the side wall; when the flood gate is closed, the rubber waterstops of the first, second and third water stopping structures are in close contact with the flood gate to realize water stopping.
The flood gate in this embodiment is made of stainless steel, has the same width as the road and the same height as the wave wall, and has a thickness of 0.5 cm-1.0 cm. The side wall is poured on the bank side of the bank road, a reinforced concrete structure which is 30-50 cm thick and is as high as the wave wall is cast in place, the function of a flood gate door frame is achieved, the grade of concrete is not lower than C25, and the concrete is graded.
In order to reduce resistance, the flood gate adopts roller wheels to move; in order to facilitate operation and play a role of effective water stopping, the hidden gate slot of the hidden gate slot is adopted to protect the downstream side edge of the dam crest highway and the downstream side edge of the reservoir bank highway by stainless steel angle protectors. In the non-flood season, the flood gate is pushed to the downstream side of the wave wall to be placed; and in the flood season, the flood control door is pushed out to block water.
