Problems solved by technology

Existing sprayers already have the function of automatically adjusting power and spraying volume. However, in the process of controlling the temperature of the concrete tank surface, there is no way to adaptively adjust the power and spraying volume of the sprayer according to the collected parameters such as the temperature of the concrete tank surface. method

Embodiment Construction

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

[0052] The self-adaptive control method for the microclimate of the concrete warehouse surface disclosed by the present invention includes:

[0053] 1. Heat of hydration temperature rise during pouring.

[0054] The equivalent hydration exotherm time is:

[0055]

[0056] Among them, T c is the initial temperature of the adiabatic temperature rise test block; T 1 is the storage temperature; is the equivalent hydration exothermic time, that is, the time when the adiabatic temperature rise test is carried out; Aτ is the interval time for paving the thin layer.

[0057] The temperature rise caused by the exotherm of hydration is It is best obtained directly from experimental data. When the experimental data is lacking but the adiabatic temperature rise fitting formula is available, the temperature rise caused by the heat release of hyd...

Abstract

The invention discloses a concrete placement surface microclimate adaptive control method. Temperature, wind speed, solar radiation and other parameters of the concrete placement surface and the water temperature parameters of a spraying machine acquired by a data acquisition subsystem are utilized, the target spraying volume required by the concrete placement surface is determined according to the preset target casting temperature, and the power of the spraying machine is adaptively adjusted according to the calculated target spraying volume so that the spraying volume of the spraying machine is enabled to reach the target spraying volume and the concrete placement surface is enabled to achieve the target casting temperature. The spraying volume can be adaptively adjusted according to various parameters of the concrete placement surface acquired in real time based on the present concrete placement surface microclimate control system so that accurate control and adjustment of the temperature of the concrete placement surface can be realized.

Description

technical field [0001] The invention relates to a microclimate self-adaptive control method for a concrete warehouse surface, belonging to the technical field of water conservancy and hydropower engineering. Background technique [0002] Controlling the pouring temperature is one of the important measures for concrete temperature control and anti-cracking, and controlling the ambient temperature of the concrete warehouse surface is an important means of controlling the pouring temperature. [0003] Chinese patent CN201520908963.1 discloses a concrete warehouse surface microclimate control system, which includes a spray mechanism, a data acquisition subsystem, and a warehouse surface climate control subsystem. The climate data (temperature and humidity data, temperature and humidity data, Wind speed data, solar radiation data, etc.) are transmitted to the climate control subsystem of the warehouse surface, and the climate control subsystem of the warehouse surface controls th...
