Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically to a cooling system for the interior of large-volume concrete. Background Technology

[0002] Concrete pouring is a crucial step in construction engineering, directly impacting the quality and stability of buildings. During the setting process, cement and water undergo a chemical reaction, releasing a significant amount of heat. If effective temperature control is not implemented during concrete pouring, cracks can easily form on-site after the concrete sets, affecting the quality of construction. Therefore, this invention proposes a novel internal cooling system for large-volume concrete. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model provides a large-volume concrete internal cooling system with a novel and reasonable structural design.

[0004] The technical solution of this utility model is as follows:

[0005] A large-volume concrete internal cooling system includes a foundation pit, a water collection well, and a steel mesh. Multiple built-in temperature sensors are arranged on the steel mesh. Drainage ditches are located around the perimeter of the foundation pit. The water collection well is equipped with an inlet / outlet device A, which is connected to the drainage ditches. A water tank is located outside the foundation pit, and an inlet / outlet device B is installed inside the water tank. The drainage ditches and the water tank are connected via drainage device B. After concrete is poured into the foundation pit, a concrete layer is formed, and multiple external temperature sensors are installed on the surface of the concrete layer.

[0006] Furthermore, the water inlet and outlet device A includes an inlet pipe A, an outlet pipe A, and a water pump. The water pump is installed in the water collection well, the outlet pipe A is connected to the water pump, and the inlet pipe A is equipped with an electrically controlled valve.

[0008] Furthermore, the internal cooling system for large-volume concrete also includes a control system, which includes a data acquisition unit, a computer processing unit, and a mobile client. The data acquisition unit is electrically connected to the built-in temperature sensor, the external temperature sensor, the electrically controlled valve, and the water pump. The data acquisition unit is electrically connected to the computer processing unit, and the computer processing unit is wirelessly connected to the mobile client.

[0009] Furthermore, the drainage ditch is higher than the collection well, water enters the drainage ditch and the collection well by gravity, and water is discharged between the drainage ditch and the collection well by a pump.

[0010] Furthermore, the water tank is lower than the drainage ditch, water enters the drainage ditch and water tank by gravity, and water exits the water tank and drainage ditch by a pump.

[0011] Furthermore, the built-in temperature sensor corresponds in position to the external temperature sensor.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1) This utility model effectively detects the temperature inside and outside the concrete by setting internal and external temperature sensors inside and outside the concrete, thereby effectively obtaining the temperature difference between the inside and outside of the concrete.

[0014] 2) This utility model utilizes the existing water collection well structure inside the foundation pit to control the temperature difference of the concrete and prevent cracks from forming after the concrete sets.

[0015] 3) The water pool set outside the foundation pit in this utility model can effectively dissipate heat from the water inside the water collection well and realize water circulation.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-2As shown, the internal cooling system for large-volume concrete includes a foundation pit 1, a drainage ditch 2, an internal temperature sensor 3, a steel mesh 4, a water collection well 5, an inlet pipe B6, an electrically controlled valve 7, a water tank 8, a water pump 9, an outlet pipe B10, an inlet pipe A11, an outlet pipe A12, a data collector 13, a computer processing device 14, a mobile client 15, and an external temperature sensor 16.

[0022] A water collection well 5 and a steel mesh 4 are installed inside the foundation pit 1; a drainage ditch 2 is set around the foundation pit 1, and the bottom of the drainage ditch 2 is higher than the water collection well 5. Water enters the drainage ditch 2 and the water collection well 5 through gravity, and water is drained from the water collection well 5 and the drainage ditch 2 through a pump.

[0023] Therefore, this utility model is equipped with an inlet and outlet device A, including an inlet pipe A11, an outlet pipe A12 and a water pump 9. The water pump 9 is a submersible pump installed in the water collection well 5. The outlet pipe A12 is connected to the water pump 9 and the water pump controls the drainage. The inlet pipe A is equipped with an electric control valve 7 and the electric control valve 7 controls the water intake.

[0024] The water tank 8 is located outside the foundation pit 1. The bottom of the drainage ditch 2 is higher than the water tank 8. Water enters the drainage ditch 2 and the water tank 8 through gravity. Water is drained from the water tank 8 and the drainage ditch 2 through a pump.

[0025] Therefore, this utility model is equipped with an inlet and outlet device B, including an inlet pipe B6, an outlet pipe B10 and a water pump 9. The water pump 9 is a submersible pump installed in the water tank 8. The outlet pipe B10 is connected to the water pump 9. An electrically controlled valve 7 is provided on the inlet pipe B10.

[0026] Nine built-in temperature sensors 3 are installed on the steel mesh 4, respectively located in the middle and on both sides of the steel mesh 4. After concrete is poured into the foundation pit, a concrete layer is formed. External temperature sensors 16 are installed on the surface of the concrete layer. The number and position of external temperature sensors 16 should correspond to those of built-in temperature sensors 3.

[0027] The control system enables the present invention to achieve automated control. The control system includes a data acquisition unit 13, a computer processing unit 14, and a mobile client 15. The data acquisition unit 13 is connected to the built-in temperature sensor, the external temperature sensor, the electrically controlled valve, and the water pump by electrical signals (in this embodiment, a wired connection can be used). The data acquisition unit 13 is connected to the computer processing unit 14 by electrical signals (in this embodiment, a wired connection can be used). The computer processing unit 14 is connected to the mobile client 15 by wireless signals (in this embodiment, a WIFI wireless connection can be used).

[0028] Working principle:

[0029] After all the concrete has been poured, the control system fills the water collection well with water, and the final water volume is higher than the concrete surface layer; at this time, while cooling the concrete, it can also cure the concrete.

[0030] When the temperature difference between the inside and outside of the concrete, as monitored by the built-in and external temperature sensors, exceeds T degrees Celsius, the control system controls the water pump to draw the hot water in the foundation pit to the cooling water pool outside the foundation pit for heat dissipation. After heat dissipation, the system controls the electronically controlled valve to send the hot water back into the foundation pit to cool the inside of the concrete, thereby reducing the internal heat of the large-volume concrete.

[0031] Mobile clients can be used to view the real-time dynamics of the control system, allowing technicians to effectively understand the on-site construction situation without leaving their offices.
