Abstract

The invention discloses anice-water two-phase flow water conveyancechannel gate section ice plugpreventing and controlling method. A strong water flow is formed through rapid shut-off and rapid full opening of a gate so as to regulatewaterpower and dredge floating ice, the parameter measurement is easy to implement,the calculation scheme is simple, the implementation method is simple and low in cost, the effect is remarkable,the problem of floating ice blockage which is easy to occur in the section of agate pier of a water conveyance channel in an ice-water two-phase flow water conveyance project is solved, and safe water conveyance of the ice-water two-phase flow water conveyance channel is realized.

Description

technical field [0001] The invention relates to the field of water delivery engineering, in particular to a method for preventing ice plugging at gate sections of ice-water two-phase flow water delivery channels. Background technique [0002] Ice-water two-phase flow water transportation is a technology that increases the ice transportation capacity of the channel by controlling the water flow conditions in the channel, prevents the flow ice from stagnating and sticking in the channel to form an ice sheet, and enables the ice to be transported downstream together with the water flow. In the engineering environment of the existing wide and shallow channels, no engineering transformation is required, and reasonable hydraulic control can realize the two-phase flow of ice and water in winter, which can not only alleviate the contradiction of water supply, but also reduce the economic cost , has huge social and economic benefits. Research on ice-water two-phase flow water transp...
