Abstract

The invention provides a drainage hole for a water conservancy project. According to the drainage hole for the water conservancy project, a steel pipe penetrating through a weir body is arranged, andthe steel pipe is connected with steel bars, so that the fixing performance of a drainage device is improved; a cover plate is arranged and is used for achieving control on the working state of the drainage device; and a sliding groove is arranged to realize the movement of the cover plate, so that the working efficiency of the drainage device is improved.

Description

technical field [0001] The invention relates to water conservancy projects, in particular to a method for constructing discharge holes for water conservancy projects. Background technique [0002] Water conservancy projects are an important form of engineering in my country. According to their functions, they can be divided into flood control buildings, irrigation, power generation and other building forms. In water conservancy projects, buildings often have the functions of water retaining and drainage. Especially for the dam body used in the reservoir and the cofferdam structure in the construction process, it is often necessary to install a discharge device to vent excess water. [0003] The discharge device is generally divided into surface flow and low flow. Surface flow is the discharge of water flow on the surface of hydraulic structures. This discharge method often requires the dam or weir to have anti-scouring protection devices, and generally requires hydraulic eng...
