Description

Technical Field

[0001] The utility model relates to the technical field of concrete temperature measurement, in particular to a temperature measurement device for preventing the concrete of the sewage tank wall from cracking. Background Art

[0002] The sewage treatment containers are basically pool structures constructed of reinforced concrete. The pool walls are all thin-walled structures. The construction of the pool wall concrete occupies a very important position and has high requirements for crack resistance, seepage prevention, and anti-corrosion. Therefore, the key to the success or failure of a sewage treatment plant is the quality control of the pool wall construction. One of the main reasons for the generation of concrete cracks is the temperature difference of the concrete. The organization and implementation of the temperature measurement work are not in place, and it is difficult to control the generation of cracks. Therefore, it is necessary to arrange temperature measurement points in the concrete, conduct temperature measurement at fixed times and locations, and monitor the change of temperature difference to guide the maintenance work.

[0003] In a concrete thermometer for concrete detection disclosed in the existing patent publication number CN213021963U, it includes a concrete thermometer outer casing. A first display screen is fixedly installed on the upper surface of the concrete thermometer outer casing. A second display screen is fixedly installed below the first display screen. A lighting button is fixedly installed on the left side below the second display screen. A switch is fixedly installed on the right side below the second display screen. A connection hole is opened at the right end of the front surface of the concrete thermometer outer casing. A first fixing box is fixedly installed at the right end of the concrete thermometer outer casing. A first fixing hole is opened on the rear surface of the first fixing box. A second fixing hole is opened on the front surface of the first fixing box. A second fixing box is fixedly installed in front of the first fixing box.

[0043] A dedicated curing team is established and supervised for implementation. After the concrete is poured, it is leveled according to the elevation and scraped flat with a wooden bar. Before initial setting, it is rolled twice with an iron roller and then smoothed with a wooden float. After the surface dries and hardens, a layer of plastic cloth is closely attached to prevent the loss of moisture on the concrete surface; then two layers of gunny bags are covered and watered to keep them moist, and the covering materials are increased or decreased according to the temperature change trend and temperature control data to control the temperature difference between the inside and outside of the concrete within 25°C. When the day-night temperature difference is large or the weather report predicts heavy rain, sufficient heat preservation materials are prepared on-site;

[0044] In order to reduce the pouring temperature of the concrete, the pouring temperature of the concrete should be controlled at about 15°C. The formwork and insulation layer can be removed only after the temperature difference between the inside and outside of the concrete is less than 25°C. If the temperature difference between the inside and outside of the concrete is greater than 25°C after formwork removal, heat preservation materials should be promptly covered to allow it to cool slowly.

[0045] The above are only the preferred embodiments of the present utility model, and it is not a limitation of the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
