[0042] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a mass concrete pouring temperature control method, comprising:

[0044] Step 11, obtaining real-time temperature information of multiple temperature measuring points inside multiple pouring layers of concrete, as well as external air temperature information;

[0045] Step 12, obtaining temperature difference information between two adjacent pouring layers of multiple concrete according to the multiple sets of real-time temperature information and the outside air temperature information;

[0046] Step 13, obtaining cooling water supply parameters corresponding to multiple pouring layers of multiple concrete according to the multiple temperature difference information and the multiple sets of real-time temperature information;

[0047] Step 14: Cooling the multiple pouring layers of concrete by water according to the multiple cooling water supply parameters.

[0048] In this embodiment, real-time temperature information of multiple temperature measuring points inside multiple casting layers of concrete and external air temperature information are obtained; temperature difference information between two adjacent casting layers of multiple concrete is obtained based on multiple groups of the real-time temperature information and the external air temperature information; cooling water supply parameters corresponding to multiple casting layers of multiple concrete are obtained based on the multiple temperature difference information and the multiple groups of the real-time temperature information; multiple casting layers of concrete are respectively water-cooled according to the multiple cooling water supply parameters; multiple casting layers of concrete can be correspondingly water-cooled according to the real-time temperature information inside the multiple casting layers of concrete, so that the temperature of the multiple casting layers of concrete can be ensured to be within a safe temperature range to avoid temperature cracks.

[0049] like Figure 2 and Figure 3 As shown, in an optional embodiment of the present invention, the temperature measuring device includes:

[0050] The first temperature sensors 2 are embedded in multiple casting layers of concrete. The first temperature sensors 2 in each casting layer of concrete are arranged in an array, and the first temperature sensors 2 in adjacent rows are staggered. All the first temperature sensors 2 are electrically connected to the control system through connecting wires.

[0051] A second temperature sensor is arranged outside, and the second temperature sensor is electrically connected to the control system.

[0052] In this embodiment, all the first temperature sensors 2 are used to measure the temperature of multiple temperature measuring points inside multiple pouring layers of concrete, thereby obtaining real-time temperature information of multiple temperature measuring points inside multiple pouring layers of concrete;

[0053] The temperature of the outside air is measured by the second temperature sensor, thereby obtaining the outside air temperature information.

[0054] In an optional embodiment of the present invention, step 12 includes:

[0055] Step 121, obtaining first temperature difference information between two adjacent pouring layers of multiple concretes according to the multiple sets of real-time temperature information;

[0056] Step 122, obtaining second temperature difference information between the topmost casting layer of concrete and the outside air according to the real-time temperature information corresponding to the topmost casting layer of concrete and the outside air temperature information.

[0057] In this embodiment, by obtaining the first temperature difference information between two adjacent pouring layers of multiple concretes according to the multiple sets of real-time temperature information, the temperature difference between two adjacent pouring layers of concrete can be understood;

[0058] By obtaining the second temperature difference information between the topmost casting layer of concrete and the outside air according to the real-time temperature information corresponding to the topmost casting layer of concrete and the outside air temperature information, the temperature difference between the topmost casting layer of concrete and the outside air can be understood;

[0059] This makes it easy to obtain subsequent cooling water supply parameters based on the temperature difference between two adjacent casting layers of concrete and the temperature difference between the top casting layer of concrete and the outside air, so that water cooling of multiple casting layers of concrete can be carried out according to the cooling water supply parameters, which can ensure that the temperatures of multiple casting layers of concrete are within a safe temperature range and avoid temperature cracks.

[0060] In an optional embodiment of the present invention, step 121 includes:

[0061] Step 1211, performing average processing on the multiple groups of the real-time temperature information respectively to obtain average temperature information inside multiple pouring layers of multiple concretes;

[0062] Step 1212: compare and process the average temperature information corresponding to two adjacent pouring layers of concrete to obtain first temperature difference information between two adjacent pouring layers of multiple concrete.

[0063] In this embodiment, since multiple temperature measuring points are arranged inside each pouring layer of concrete, the real-time temperature information of these temperature measuring points is averaged to obtain the average temperature information inside each pouring layer of concrete. The average temperature information can accurately reflect the temperature condition inside each pouring layer of concrete.

[0064] By comparing and processing the average temperature information corresponding to two adjacent casting layers of concrete, the first temperature difference information between two adjacent casting layers of multiple concrete is obtained, so that the temperature difference between two adjacent casting layers of concrete can be understood, and it is convenient to obtain the cooling water supply parameters of each casting layer of concrete according to the first temperature difference information. According to the cooling water supply parameters, each casting layer of concrete is subjected to corresponding water cooling, which helps to ensure the water cooling effect and can ensure that the temperatures of multiple casting layers of concrete are within a safe temperature range, thereby avoiding the generation of temperature cracks.

[0065] In an optional embodiment of the present invention, step 122 includes:

[0066] Step 1221, compare the average temperature information corresponding to the topmost pouring layer of concrete with the outside air temperature information to obtain second temperature difference information between the topmost pouring layer of concrete and the outside air.

[0067] In this embodiment, by comparing the average temperature information corresponding to the topmost casting layer of concrete with the outside air temperature information, the second temperature difference information between the topmost casting layer of concrete and the outside air is obtained; the temperature difference between the topmost casting layer of concrete and the outside air can be understood, so that the cooling water supply parameters corresponding to the topmost casting layer of concrete are obtained according to the second temperature difference information, and the topmost casting layer of concrete is water-cooled by the cooling water supply parameters to avoid cracks in the topmost casting layer of concrete caused by excessive temperature difference between the topmost casting layer of concrete and the outside air.

[0068] In an optional embodiment of the present invention, step 13 includes:

[0069] Step 131, obtaining cooling water supply flow rate parameters corresponding to multiple pouring layers of multiple concrete according to the multiple temperature difference information;

[0070] Step 132, obtaining cooling water supply temperature parameters according to the multiple sets of real-time temperature information.

[0071] In this embodiment, the temperature difference information can reflect the temperature difference between two adjacent concrete casting layers. The cooling water supply flow rate parameters corresponding to the two adjacent concrete casting layers are determined according to the temperature difference information. According to the temperature difference between the two adjacent concrete casting layers, the cooling water supply flow rates of the two casting layers are controlled, so that the two casting layers are adapted to water cooling and cooling, the water cooling effect is ensured, and cracks are avoided due to excessive temperature difference between the two adjacent casting layers.

[0072] By obtaining cooling water supply temperature parameters based on multiple groups of real-time temperature information, it is possible to obtain cooling water supply temperature parameters based on the real-time temperature information of multiple concrete casting layers, thereby controlling the temperature of the supplied cooling water, while ensuring the water-cooling effect on the multiple concrete casting layers, avoiding excessive temperature difference between the supplied cooling water and the multiple concrete casting layers, which may cause local cracks in the multiple concrete casting layers.

[0073] In an optional embodiment of the present invention, step 131 includes:

[0074] Step 1311, comparing the plurality of temperature difference information with a preset first temperature difference threshold, to obtain first comparison information corresponding to a plurality of pouring layers of a plurality of concretes;

[0075] Step 1312: obtaining cooling water supply flow rate parameters corresponding to multiple pouring layers of multiple concrete according to the multiple first comparison information.

[0076] In this embodiment, by comparing the plurality of temperature difference information with a preset first temperature difference threshold, first comparison information corresponding to a plurality of pouring layers of a plurality of concrete is obtained, so that it can be known whether the temperature difference information between two adjacent pouring layers of concrete is greater than the preset first temperature difference threshold;

[0077] When the temperature difference information between two adjacent casting layers of concrete is greater than a preset first temperature difference threshold, the cooling water supply flow rate parameter is to increase the flow rate, thereby increasing the cooling water supply speed of the casting layer with a higher temperature among the two adjacent casting layers of concrete, thereby increasing the cooling water supply amount of the casting layer, thereby increasing the cooling effect of the casting layer;

[0078] When the temperature difference information between two adjacent pouring layers of concrete is not greater than a preset first temperature difference threshold, the cooling water supply flow rate parameter is to maintain the flow rate;

[0079] When the temperature difference information between two adjacent pouring layers of concrete is less than a preset first temperature difference threshold, and the temperature difference information between two adjacent pouring layers of concrete gradually decreases, the cooling water supply flow rate parameter is to reduce the flow rate;

[0080] By using the above method, the cooling water supply flow rate parameters corresponding to the multiple pouring layers of the multiple concrete are obtained according to the temperature difference information, so that the multiple pouring layers of the concrete are cooled by water according to the cooling water supply flow rate parameters to ensure the cooling effect and avoid cracks caused by excessive temperature difference between two adjacent pouring layers;

[0081] In this embodiment, the preset first temperature difference threshold is 20°C. When the temperature difference information between two adjacent pouring layers of concrete is greater than 20°C, the cooling water supply speed of the pouring layer with a higher temperature among the two adjacent pouring layers of concrete is increased;

[0082] In this embodiment, it is also necessary to obtain the cooling water supply flow rate parameters according to the preset temperature reduction limit threshold; the specific preset temperature reduction limit threshold is 1°C / day, that is, when determining and adjusting the cooling water supply flow rate parameters, it is necessary to refer to the preset temperature reduction limit threshold so that the cooling rate of multiple concrete casting layers cannot exceed 1°C / day. The cooling water supply flow rate parameters are determined and adjusted through the above process in conjunction with the first comparison information, thereby ensuring the cooling effect while avoiding cracks caused by excessive cooling of multiple concrete casting layers.

[0083] In an optional embodiment of the present invention, step 132 includes:

[0084] Step 1321, performing average processing on the multiple groups of the real-time temperature information respectively to obtain average temperature information inside multiple pouring layers of multiple concretes;

[0085] Step 1322, averaging the plurality of average temperature information to obtain target average temperature information;

[0086] Step 1323: obtaining a cooling water supply temperature parameter according to the target average temperature information and a preset second temperature difference threshold.

[0087] In this embodiment, the average temperature information inside the multiple pouring layers of the multiple concretes is obtained by respectively averaging the multiple groups of the real-time temperature information; the target average temperature information is obtained by averaging the multiple average temperature information; the cooling water supply temperature parameter is obtained according to the target average temperature information and the preset second temperature difference threshold; the cooling water supply temperature parameter is conveniently determined and adjusted, and while ensuring the water cooling effect on the multiple pouring layers of the concrete, the temperature difference between the supplied cooling water and the multiple pouring layers of the concrete is avoided to be too large, causing local cracks in the multiple pouring layers of the concrete;

[0088] In this embodiment, the preset second temperature difference threshold is 20°C, and the target average temperature information is obtained by averaging the multiple average temperature information; the target average temperature information is obtained by averaging the multiple average temperature information; the cooling water supply temperature parameter is determined by the target average temperature information and 20°C, thereby determining the temperature of the supplied cooling water, so that the temperature difference between the temperature of the supplied cooling water and the average temperature information inside the multiple casting layers of concrete does not exceed 20°C, while ensuring the water cooling effect on the multiple casting layers of concrete, avoiding excessive temperature difference between the supplied cooling water and the multiple casting layers of concrete, causing local cracks in the multiple casting layers of concrete.

[0089] like Figure 4 and Figure 5 As shown, in an optional embodiment of the present invention, the water supply device includes:

[0090] Pre-buried water pipes 31 are pre-buried in multiple pouring layers of concrete. Multiple pre-buried water pipes 31 are provided in each pouring layer of concrete, and the multiple pre-buried water pipes 31 are independently provided to form an independent waterway structure; the water inlet end of the waterway structure formed by each pre-buried water pipe 31 goes deep into the water inlet pool 32 and is connected to a water inlet pump, which is electrically connected to the control system, and the water outlet end of the waterway structure formed by each pre-buried water pipe 31 goes deep into the water outlet pool 33;

[0091] A water supply pipe, one end of which penetrates into the groundwater, and the other end of which penetrates into the water inlet pool 32 and is connected to a water supply pump, which is electrically connected to the control system;

[0092] A return pipe, one end of which extends into the outlet pool 33 and is connected to a return water pump, the return water pump is electrically connected to the control system, and the other end of the return pipe extends into the inlet pool 32;

[0093] The stirring assembly disposed inside the water inlet pool 32 is used to stir the water inside the water inlet pool 32 so that the water temperature of the cooling water inside the water inlet pool 32 is evenly distributed;

[0094] A third temperature sensor disposed inside the water inlet pool 32 is used to measure the temperature of the cooling water inside the water inlet pool 32, and the third temperature sensor is electrically connected to the control system;

[0095] A fourth temperature sensor is provided inside the water inlet end of the water channel structure formed by each pre-buried water pipe 31, and is used to measure the temperature of the cooling water entering the water inlet end of the water channel structure formed by the pre-buried water pipe 31, and the fourth temperature sensor is electrically connected to the control system;

[0096] A water flow rate sensor is arranged inside the water inlet end of the water channel structure formed by each pre-buried water pipe 31, and the water flow rate sensor is electrically connected to the control system.

[0097] In this embodiment, the water in the outlet pool 33 is injected into the inlet pool 32 through the return water pump and the return water pipe, and the groundwater is injected into the inlet pool 32 through the replenishment water pump and the replenishment water pipe, so as to achieve the temperature regulation of the cooling water in the inlet pool 32;

[0098] When the cooling water supply temperature parameter is obtained, the cooling water supply temperature parameter is compared with the temperature of the cooling water inside the water inlet pool 32 measured by the third temperature sensor. When the temperature of the cooling water inside the water inlet pool 32 is greater than the cooling water supply temperature parameter, groundwater is injected into the water inlet pool 32 through the water supply pump and the water supply pipe, so that the temperature of the cooling water inside the water inlet pool 32 is gradually reduced until it matches the cooling water supply temperature parameter; when the temperature of the cooling water inside the water inlet pool 32 is less than the cooling water supply temperature parameter, water inside the water outlet pool 33 is injected into the water inlet pool 32 through the return water pump and the return water pipe, so that the temperature of the cooling water inside the water inlet pool 32 is gradually increased until it matches the cooling water supply temperature parameter;

[0099] The temperature of the cooling water entering the water inlet end of the water channel structure formed by the embedded water pipe 31 is measured by the fourth temperature sensor to ensure that the temperature of the cooling water injected into the embedded water pipe 31 is compatible with the cooling water supply temperature parameter, thereby ensuring the water cooling effect and cooling accuracy of multiple concrete pouring layers;

[0100] The cooling water flow rate of the pre-buried water pipe 31 corresponding to the multiple pouring layers of concrete is measured by a water flow rate sensor, so that the cooling water flow rate of the pre-buried water pipe 31 corresponding to the multiple pouring layers of concrete is adapted to the cooling water supply flow rate parameter, thereby ensuring the water cooling effect and cooling accuracy of the multiple pouring layers of concrete;

[0101] The cooling water supply temperature parameter may be a temperature range or a specific temperature value.

[0102] In an optional embodiment of the present invention, step 14 includes:

[0103] Step 141, adjusting the temperature of the cooling water according to the cooling water supply temperature parameter so that the temperature of the supplied cooling water matches the cooling water supply temperature parameter;

[0105] In this embodiment, the cooling water supply temperature parameter is compared with the temperature of the cooling water inside the water inlet pool 32 measured by the third temperature sensor. When the temperature of the cooling water inside the water inlet pool 32 is greater than the cooling water supply temperature parameter, groundwater is injected into the water inlet pool 32 through the water supply pump and the water supply pipe, so that the temperature of the cooling water inside the water inlet pool 32 is gradually reduced until it matches the cooling water supply temperature parameter; when the temperature of the cooling water inside the water inlet pool 32 is lower than the cooling water supply temperature parameter, water inside the water outlet pool 33 is injected into the water inlet pool 32 through the return water pump and the return water pipe, so that the temperature of the cooling water inside the water inlet pool 32 is gradually increased until it matches the cooling water supply temperature parameter;

[0106] In the initial stage of cooling, cooling water is injected into the pre-buried water pipes 31 corresponding to the multiple concrete casting layers at a preset flow rate through multiple water inlet pumps. When the cooling water supply flow rate parameter is to increase the flow rate, the power of the water inlet pump is increased, thereby increasing the cooling water flow rate inside the pre-buried water pipe 31, increasing the amount of cooling water injected into the pre-buried water pipe 31, and improving the cooling rate; when the cooling water supply flow rate parameter is to maintain the flow rate, no adjustment is made; when the cooling water supply flow rate parameter is to reduce the flow rate, the power of the water inlet pump is reduced, thereby reducing the cooling water flow rate inside the pre-buried water pipe 31, reducing the amount of cooling water injected into the pre-buried water pipe 31, and reducing the cooling rate; while ensuring the cooling effect, ensure that the temperature of the multiple concrete casting layers is within a safe temperature range to avoid temperature cracks; at the same time, the cooling efficiency of the multiple concrete casting layers is not higher than 1°C / day.
