Abstract

Disclosed are a construction method of fishway and an under earth type fishway, in which the under earth fishway is constructed by a water outlet wall of a water level differentiating structure that is set across a river bed. The two sides of the water level differentiating structure respectively form a high water level interception zone and a low water level waterfall zone. An entrance of under earth type fishway is connected to the waterfall zone of the water level differentiating structure and an exit of the under earth type fishway is connected to the interception zone of the water level differentiating structure. The construction method of fishway and the under earth type fishway can be constructed at the same time when a new water level differentiating structure or made as an annexed construction of an existing water level differentiating structure, so that the area of construction site need in the present invention can be reduced dramatically and the restraint conditions by the geology environment become less. Not only the area needs of the construction can be reduced, but also can convenience be increased, while costs can be reduced.
