Summary:The invention discloses a method for reducing negative pressure at the bottom of a plane gate and a plane gate structure thereof. The method comprises the following steps: 1, setting the lower part ofa sand blocking plane gate as a double-panel box type gate leaf, wherein a bottom edge sealing plate of the double-panel box type gate leaf is an inclined plane which is inclined towards the upper part of the downstream side, and a water leakage opening is formed in a cross beam web in the double-panel box type gate leaf; and 2, transversely arranging an arc pipe groove with a downward opening inthe plate surface of the bottom edge sealing plate along the plane gate, then arranging a vertical pipe in the double-panel box type gate leaf, wherein the vertical pipe penetrates through the crossbeam web in the double-panel box type gate leaf, a lower pipe opening of the vertical pipe is communicated with the arc pipe groove, and an upper pipe opening of the vertical pipe extends out of the upper part of the sand block
