Problems solved by technology

[0002] The problem of temperature control and anti-cracking of large-volume concrete has long plagued project builders, and water cooling is an important measure for temperature control and anti-cracking. Traditionally, the method of water cooling is artificial water. This method has the following Problems: (1) The adjustment of water flow is manual, which is time-consuming and laborious; (2) In the process of water cooling, fixed water temperature and flow rate are used for a certain period of time, which cannot realize real-time adjustment of water flow, and the cooling rate cannot be effectively guaranteed ; (3) The authenticity of the water supply data and the water supply process is greatly affected by people's subjective ideology, and the authenticity and timeliness of the water supply data cannot be guaranteed

Embodiment Construction

[0030] The intelligent water flow method of this mass concrete comprises the following steps:

[0031] (1) start;

[0032] (2) Store historical data including meteorology, hydrology, materials, and construction information in the database as basic data;

[0033] (3) According to different material partitions, the finite element method is used to determine the ideal temperature process line of concrete in different partitions;

[0034] (4) After the concrete is poured, record the water temperature, flow rate, internal temperature of the concrete, and weather forecast information in real time, and send these information to the database;

[0035] (5) According to step 4 and formulas (1)-(6), calculate and predict the next day's concrete

[0036] T 1 (t)=T w +(T 0 -T w )e -pt +θ 0 Ψ(t)+ΔT 外界 (1)

[0037] where the temperature of the concrete is T w , the initial temperature of concrete is T 0 , the adiabatic temperature rise is θ 0 f(τ), the inlet water ...

Abstract

The invention discloses a mass concrete intelligent water communication method. The method comprises that steps of (1) starting water communication; (2) storing historical data containing weather, hydrological, material and construction information into a database as basic data information; (3) according to different material partitions, determining the ideal temperature process lines of concrete of different partitions through the finite element method; (4) after the concrete is poured, recording real-time water temperature, water flow, concrete internal temperature and weather forecast information and sending the information to the database; (5) according to the real-time water temperature, the water flow, the concrete internal temperature and the weather forecast which are provided in the step (4) and the temperature process lines, calculating water communication cooling flow of a next stage for every cell; (6) transmitting an instruction of the water communication cooling flow to a water communication system to achieve automatic regulation of the water communication cooling flow; (7) ending the water communication. The invention also provides a mass concrete intelligent water communication system.
