Problems solved by technology

The weir wall and floor of this kind of labyrinth weir are generally integral structures, and the weir wall is a cantilever structure. The root of the weir wall and the weir wall transmit relatively large bending moments to the floor. Correspondingly increased, so this labyrinth weir structure still has the shortage of large engineering investment

Embodiment Construction

[0006] The supported labyrinth weir of the present invention comprises that a concrete bottom plate 4 is provided on the riverbed in the diversion wall 1, and the labyrinth weir wall 2 is fixedly connected on the bottom plate 4, and four walls are evenly arranged between the outer sides of the two opposite weir walls. A horizontal support beam 3, the reinforcement at both ends of the support beam is connected with the hidden beam reinforcement at the upper part of the weir wall body, and the weir wall and the support beam form an integral structure. When the outermost horizontal support beam was longer, the span of the beam was larger at this moment, and the horizontal support could be changed into two oblique support beams 5, and the two ends of the support beam were connected with the concealed beam and the base plate of the weir wall respectively. The support beams can be prefabricated in the prefabrication plant, and then cast in one piece with the weir wall on site. The s...

Abstract

The supporting labyrinth weir includes underplate and labyrinth weir walls, and features that in the upper part of two-to-two opposite weir walls, horizontal supporting beam is set and the outmost support beam is horizontal supporting beam or inclined supporting beam with upper end connected to the weir walls and the lower end to the underplate. Owing to the horizontal support beams in the equal distance and in the upper part of outside the weir walls, there are no cantilever beam stress state resulting in small size of weir wall and underplate cross section size, less reinforcing bars and low engineering cost.

Description

Technical field: [0001] The invention relates to a water conservancy engineering technology, in particular to a supporting labyrinth weir for reservoir overflow. Background technique: [0002] Labyrinth weir is a new type of overflow weir, which has larger overflow capacity than conventional overflow weirs, less engineering investment, convenient management and maintenance, and is widely used. The weir wall and floor of this kind of labyrinth weir are generally integral structures, and the weir wall is a cantilever structure. The root of the weir wall and the weir wall transmit relatively large bending moments to the floor. Correspondingly increased, so this labyrinth weir structure still has the deficiency of large engineering investment. Invention content: [0003] The technical problem to be solved in the present invention is to design a labyrinth weir, which is a supported labyrinth weir with small cross-sectional dimensions of the weir wall and bottom plate, small am...
