[0041] See also Figures 1 to 5 , the figure shows a diagonally-stayed floating tide gate, including left and right gate piers 100a, 100b, a gate bottom plate 200, a pontoon gate 300 and a support locking device 400.
[0042] The left and right gate piers 100a and 100b are symmetrically constructed on the left and right sides of the river bank, and are made of reinforced concrete or steel structures. Left and right vertical gate grooves 110a and 110b are formed on the inner side surfaces of the left and right gate piers 100a and 100b, which can withstand a part of the horizontal force transmitted by the pontoon gate 300 and limit the horizontal displacement of the pontoon gate 300.
[0043] The gate bottom plate 200 is buried in the river mouth foundation and located between the left and right gate piers 100a and 100b.

A transverse accommodating gate groove 201 is formed on the upper plate surface of the gate bottom plate 200, and the transverse accommodating gate groove 201 can be used to accommodate the floating box gate 300. The gate bottom plate 200 adopts a reinforced concrete hollow box bottom plate, which includes a lower box plate 210, an upper box plate 220, a left box plate 230, a right box plate 240, a front box plate 250, a right box plate 260, a plurality of intermediate transverse partitions 270 and a plurality of intermediate longitudinal partitions 280. The lower box plate 210, the upper box plate 220, the left box plate 230, the right box plate 240, the front box plate 250 and the right box plate 260 enclose an empty box chamber.
