Flat pressure adjusting structure for rapid emptying of high dam reservoir

The invention discloses a high dam reservoir rapid emptying flat pressure adjusting structure which comprises n water retaining gate wells, n emptying gate chambers and n adjusting pools, the water retaining gate wells and the emptying gate chambers are arranged on a tunnel, the tunnel is communicated with a reservoir, the arrangement sequence of the water retaining gate wells and the emptying gate chambers is the same as the flow direction of water flow in the tunnel, and the number of the water retaining gate wells and the number of the adjusting pools are both n, along the arrangement sequence of the water retaining gate wells on the tunnel, the ith water retaining gate well is communicated with the ith regulating reservoir through a water replenishing pipe, the ith regulating reservoir is communicated with the (i + 1) th regulating reservoir through an interstage overflow gallery, and the setting elevation of the ith regulating reservoir is greater than that of the (i + 1) th regulating reservoir; the las
