Construction method for constructing overflow weir surface based on overflow weir body and combined template and overflow weir

Abstract

The invention discloses a construction method for constructing an overflow weir surface based on an overflow weir body and a combined template. The construction method is applied to the overflow weir, the overflow weir comprises the overflow weir body and a pouring body, and the surface of the pouring body is the overflow weir surface. The pouring body comprises a downstream pouring body. The construction method at least comprises the following steps that the overflow weir body is built based on the design form of the pouring body; on the basis of the overflow weir body, a plurality of first templates are fixed to the downstream side of the overflow weir body and connected to form a curved surface template set, and a first reserved gap is reserved between the curved surface template set and the overflow weir body; after the curved surface template set is connected to the overflow weir body, a first slope angle formed by the curved surface template set and a horizontal plane is gradually changed in the height direction; concrete is poured into the first reserved gap, so that the downstream pouring body is formed on the downstream side of the overflow weir body, and the downstream overflow weir surface is constructed. The method solves the technical problem that in the construction process of the special-shaped curved surface overflow weir, the construction quality is difficult to control.

Description

Technical field[0001]The present invention relates to the field of water conservancy engineering, and more particularly to a construction method and an overflow dam of overflow corruption based on overflow and combined templates.Background technique[0002]The dam is built into a building in the bed. One of the functions of the dam are flooding to ensure that the river water levels of the upstream are within the safety range.[0003]In the relevant prior art, when the dam under low hills and plain areas, the water head is generally low and the amount of fuel is small. Thus, in order to improve the amount of fuel, the overflow corruption is more than the shaped surface, but this osmotic surface is technically difficult to control during the construction process.Inventive content[0004]The primary object of the present invention is to provide a construction method and overflow dam construction method based on overflow and combined templates, aimed at solving the existing technique in the d...
