Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0052] In the embodiment, the intelligent humidity control dam is deployed in the western high-altitude area, which belongs to the continental north temperate zone and cold temperate zone climate. The climate is dry, with short springs and autumns and long winters and summers. The summer is cooler, the winter is more severe, and the temperature varies greatly from year to year. The geographical latitude of the project location is high, and the amount of solar radiation is small. The barrage of the water conservancy project is a concrete double-curvature arch dam with a maximum dam height of 240m. The average temperature at the dam site is 2.8°C for many years; the extreme maximum temperature is 36.6°C; the extreme minimum temperature is -45°C; the annual average precipitation is 203.8mm; The annual average evaporation is 1447.5mm; t...

Abstract

The invention relates to an intelligent humidity regulation and control dam which comprises a dam body, a concrete strength monitoring device, a humidity sensor group, a medium supply pipeline, a humidity node regulation and control unit, a relay medium pressure intensity regulation and control unit, a medium compensation source and a control mechanism, the humidity node regulation and control unit comprises a gasifier, an electric control valve, a humidity diffusion tile, a breathable film and a node controller; the control end of the gasifier and the electric control valve are electrically connected with the node controller; the medium supply pipeline is of a tree-shaped structure, the input end of the medium supply pipeline is connected with the medium compensation source, and the tail end of each branch of the medium supply pipeline is connected with the humidity node regulation and control unit. The invention further discloses a control method of the intelligent humidity regulation and control dam. The humidity node regulation and control units are arranged at the grid nodes of the dam, humidity diffusion in different directions of the grid volume units is achieved, all-directional humidity regulation and control are conducted on all areas of the dam, the concrete humidity stress increment is reduced, and concrete cracks can be effectively prevented.

Description

technical field [0001] The invention belongs to the field of dam intelligent control, and in particular relates to an intelligent humidity control dam. Background technique [0002] With the development of my country's hydropower industry, concrete dams continue to emerge in the construction of high dams. While the construction of high concrete dams continues to develop, the problem of "no dam and no cracking" of concrete dams has also attracted great attention from the academic and engineering circles. The structural performance of dam concrete is related to the cracking of concrete materials from the decline to the end of life. The cracks of dam concrete during the construction and operation periods have a significant impact on its structural safety and service life. [0003] Most of the cracking of the dam concrete structure is caused by non-load factors, that is, the expansion or contraction of the concrete volume caused by temperature changes and humidity changes in the...
