Problems solved by technology

At present, portable electronic thermometers are generally used to measure the temperature of large-volume concrete. Usually, the temperature measuring elements and temperature measuring wires are not easy to protect when pouring concrete at night, which brings great difficulty to the actual temperature measurement.
[0004] Therefore, there are above-mentioned inconveniences and problems in temperature measurement and cooling during known mass concrete pouring.

Embodiment 1

[0035] The large-volume pouring concrete temperature measuring and cooling method of the present invention comprises the following steps:

[0036] a, prefabricated temperature measuring tube and cooling tube, including the following steps:

[0037] see now figure 1 , figure 1 It is a structural schematic diagram of pre-embedded temperature measuring tubes and cooling tubes in concrete according to an embodiment of the present invention.

[0038] (1) The temperature measuring tubes are made of DN20 steel pipes, and the bottom of the temperature measuring tubes is welded and sealed with steel plates; several thermometers are provided, and each temperature measuring tube is equipped with a thermometer, and the construction line passes through the round hole at the top of the thermometer and is free Lower it to suspend at a place 5cm from the bottom of the temperature measuring tube; the maximum range of the thermometer is 100°C.

[0039] (2) The cooling pipe 5 is made of DN50 ...

Abstract

A mass pouring concrete temperature measuring and cooling method is characterized by comprising the following steps that a, a temperature tube and a cooling pipe are prefabricated; b, the temperature tube and the cooling pipe are mounted; and c, concrete is subjected to temperature measuring and cooled in the concrete pouring process. The mass pouring concrete temperature measuring and cooling method has the advantages that a temperature measuring and cooling device is simple in structure and convenient to use, the effect that measured temperature data are accurate and reliable is ensured, the process is simple, construction is convenient, and the project cost is reduced.

Description

technical field [0001] The invention relates to concrete pouring, in particular to a temperature measuring and cooling method for large-volume pouring concrete. Background technique [0002] Zhanhua Fly Ash Project No. 1 Plant Decomposition Workshop Two-stage Decomposition, Fine Seed Washing System, Aluminum Hydroxide Classification Technical Renovation Project Civil construction is mainly the concrete equipment foundation. The equipment foundation of this project is divided into tank foundation and pump foundation, among which the fine seed settlement tank foundation has a diameter of 28.8m and a thickness of 1.5m, which belongs to mass concrete. [0003] Because the heat of hydration of mass concrete cement is not easy to lose quickly, the heat is stored inside, which makes the temperature difference between inside and outside large, and cracks caused by temperature are easy to occur. Therefore, temperature control is the most prominent problem in mass concrete constructio...
