Preferably, the concrete foundation is cast in a cast-in-place pre-embedded mode. Or the second stage concrete can be selected and poured and embedded in the second stage.

Preferably, the bottom and the side of the trapezoid door leaf are provided with a first water stop rubber sheet.

Preferably, the embedded steel plate is provided with a second water stop rubber skin.

Preferably, the included angle between the bottom and the side of the trapezoid door leaf is 107-162 degrees (the corresponding channel side slope is 1: 0.3-1: 3).

Preferably, the included angle between the bottom and the side of the trapezoidal door leaf is 146 degrees (the corresponding channel side slope is 1: 1.5).

Has the advantages that: the utility model provides a trapezoidal gate possesses following substantive characteristics and progress:

1. the trapezoidal door leaf is similar to the cross section of the channel, and reduces the operation of hydraulic construction.

2. The shapes of the cross sections of the channels are relatively standard by pouring the concrete foundation and the embedded steel plates, so that the cross sections of the channels can be better matched with the trapezoidal door leaves.

3. Compared with a rectangular gate, the arrangement of the trapezoidal gate leaves is to improve the sealing property by providing downward pressure through a power system on the side edge of the gate which is originally sealed only by water pressure; meanwhile, the side edge of the trapezoidal door leaf can be directly separated from the sealing surface when the gate discharges water, so that the abrasion of the water stopping rubber skin is reduced.

4. The two ends of the trapezoidal door leaf are provided with the gate torque arms in the door slots, and the water pressure borne by the trapezoidal door leaf is resisted through the torque force between the gate torque arms and the door slots.

5. The bottom edge of the trapezoidal gate and the water stopping at the two trapezoidal side edges can be regarded as bottom water stopping. When the water level of the channel is low, the water-stop rubber can provide enough downward pressure through the opening and closing machine to keep the sealing performance. The side water stopping at two sides of the traditional rectangular gate needs to press the water stopping rubber on the side plate of the gate slot by water pressure to achieve the water stopping effect. When the depth of water in the channel in the irrigation area is shallow, the water pressure acting on side water stop is small, and the water stop effect is poor.
