CONNECTION JOINT OF OPEN WATERCOURSES Russian patent published in 2017 - IPC E02B13/00 

FIELD: construction.

SUBSTANCE: to a transit channel 1, a supply channel 2 is adjacent perpendicularly in the plan. At the end of the supply channel 2 and along the axis of its bottom, there are a bottom rectangular tray 3 with dividing walls 4, a well 5 with vertical sidewalls expanding in the plan towards the slopes of the transit channel 1. The bottom tray 3 ends with curved guiding flaps 6, which serve to guide the flow under the visors 7. The visors 7 have hinges attached to the upper ends of the sidewalls of the expanding well 5, and telescopic supports hingedly fixed from below the visor and to the well bottom. The rear wall of the well 5 is made with a reverse bias towards the longitudinal axis of the transit channel 1 and is oriented downstream of the channel. The inclination angle of the visor 7 is adjusted by the telescopic support relative to the bottom of the supply channel 2. The water flowing through the channel 2 is divided into three flows by the bottom tray 3 with dividing walls 4. The visor 7 is arranged of such a length that the jets flowing from it flow directly into the expanding well 5, which has a rear wall with the reverse bias towards the longitudinal axis of the transit channel 1 and can ensure the energy dissipation in the well 5. Thereinafter, the total flow from the well is smoothly connected to the flow of the channel 1.

EFFECT: increasing the reliability and efficiency of hydraulic conditions in the channels junction area, reducing the dynamic loads towards the longitudinal axis of the transit channel.
