[0001] 1. Technical Field
[0002] The present invention belongs to the construction technology of concrete mixing station in winter, in particular to a method for heating and insulating concrete coarse and fine aggregate in a mixing station in a shed in winter.
[0003] 2. Description of Related Art
[0004] According to relevant regulations, when mixing concrete in winter, there should be proper out-feeding temperature and concrete casting temperature, to prevent the concrete from freezing at an early stage. In order to ensure the mixing temperature of concrete, it is usually necessary to heat the mixing water or aggregate or both, and the heating temperature of aggregate shall not exceed 60°C.
[0005] The present invention provides a simple method for heating a water tank of a mixing station in a concrete shed in cold winter. The method can heat the aggregate in a qualified warehouse in the heat preservation shed and maintain a suitable temperature to meet the requirements of concrete construction in winter.
[0006] Specifically, the technical solution of the present invention is: a method for heating and insulating concrete coarse and fine aggregate in a mixing station in a shed in winter, comprising the following steps:
[0007] (1) Position setting of radiators
[0008] Install several radiators on the wall of the silo of the mixing station;
[0009] (2) Radiator installation
[0010] First install the inlet valve and return valve of the radiator, then place the radiator stably and connect the radiator into the heating pipe;
[0011] (3) Pressure test of radiator
[0012] Close the main pipe connection valve, close the inlet and return valves of the radiator, and make the test pressure 1.5 times the working pressure. If there is no leakage during the pressure test for 2-3 minutes, it is qualified;
[0013] (4) Installation of floor heating system
[0014] After the silo foundation treatment of the mixing station is completed, C20 foam concrete with a thickness of 10-15cm is applied as a heat insulating layer to isolate the downward transfer of heat; then a reflective film is laid on the heat insulating layer to prevent downward radiation heat transfer; (p100mm steel pipes are selected as floor heating pipelines, which are arranged in a circuitous way; after passing the pressure test, 30cm thick C30 concrete foundation is poured to connect the floor heating pipeline with the heating pipeline.
[0015] On the basis of the above solution, in step (1), one radiator is set for every 5-6m2 in the silo, and the size of the radiators is 180cmx60cm.
[0016] On the basis of the above solution, the reflective film in step (4) is made of non-woven fabric-based aluminum foil material.
[0017] On the basis of the above solution, the pipe center of the floor heating pipe is 15 1cm from the top surface of the heat insulating layer.
[0018] According to the present invention, a floor heating system is buried under the silo, and a certain number of radiators are installed on the walls inside the silo. The heat medium of both the radiator and the floor heating system is hot water supplied by a boiler. Heat is supplied to the silo through radiation (main) and convection (secondary) heat transfer modes, to heat the aggregate and keep the temperature at 15°C-25°C. The temperature can meet the mixing requirements. The method of the present invention is low in cost and easy to control.

[0023] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.
[0024] A method for heating and insulating concrete coarse and fine aggregate in a mixing station in a shed in winter, comprising the following steps:
[0025] 1. Radiator arrangement
[0026] As shown in Fig. 1, radiators are installed on the three walls of the silo (the silo is enclosed on three sides and one side is open for feeding and discharging) according to the standard of 1/5-6m2. Radiators can be common steel radiators in the market. The space in the insulation shed is large, thus the size can be 180cmx60cm.
[0027] 2. Radiator installation
[0028] Install the inlet valve and return valve first, measure the position of the radiator with a horizontal ruler for the fixed pendant, place the radiator smoothly, connect the valve connector with the water inlet and water outlet valves, and use a horizontal ruler to measure whether the radiator is straight and whether the pipeline installation meets the requirements. Use pipe tongs to reinforce and tighten the connector. Pressure test: Close the main pipe connection valve, close the inlet and return valves of the radiator, and make the test pressure 1.5 times the working pressure. If there is no leakage during the pressure test for 2-3 minutes, it is qualified.
[0029] 3. Installation of floor heating system
[0030] As shown in Fig. 2, after the silo foundation treatment is completed, C20 foam concrete with a thickness of 10-15cm is applied as a heat insulating layer to isolate the downward transfer of heat; then, a layer of non-woven aluminum foil material is laid on it as a reflective film to prevent downward radiation heat transfer, reduce heat loss and improve thermal efficiency. (p100mm steel pipes are selected as the floor heating pipeline, which are arranged in a circuitous way, with is supported and fixed by steel bars. The center of the pipeline is about 15cm from the top surface of the heat insulating layer. After passing the pressure test, a 30cm thick C30 concrete foundation is poured. If necessary, a layer of steel mesh can be added at the bottom to improve the compressive strength.
[0031] The working principles of the present invention are as follows:
[0032] 0 Working mode of radiator: Hot water burned in the boiler is transported to the radiator through the pipeline system to dissipate heat and heat up the air in the silo;
[0033] © working mode of floor heating: The heat medium of a floor heating system is also hot water, which circulates and flows in a heating pipeline, heats the ground evenly, and supplies heat to the silo through the ground by radiation (main) and convection (secondary) heat transfer modes;
[0034] @ the combination of the two modes improves the heating speed and effect, thus heating the aggregate piled up in the silo to a suitable temperature to meet the needs of mixing concrete in winter and keeping warm continuously.
[0035] It should be understood that although the present description is described in terms of the implementation, not every implementation includes only one separate technical solution, and such a description mode of the description is merely for the sake of clarity. A person skilled in the art should take the description as a whole, and the technical solutions in all the embodiments may be appropriately combined to form other implementations that can be understood by a person skilled in the art.
