[0014] like Figure 1 As shown, a water-cooling device for a large-volume concrete base slab includes: a dewatering well 2 formed in the concrete base slab 1; a water pump 5 installed in the dewatering well 2; and a cooling water pipe 4 embedded in the concrete base slab 1. The inlet end of the cooling water pipe 4 is connected to the water pump 5, and the outlet end extends out of the concrete base slab 1. Water from the dewatering well 3 is pumped into the cooling water pipe 4 by the water pump 5 and discharged from the cooling water pipe 4.

[0015] like Figure 1 As shown, it also includes: a three-way valve 3 located between the water pump 5 and the cooling water pipe 4, the three-way valve 3 having an inlet and a first outlet and a second outlet that can be selectively opened; an inlet pipe, one end of which is connected to the water pump 5 and the other end is connected to the inlet, the inlet end of the cooling water pipe 4 being connected to the first outlet; a drain pipe, the inlet end of which is connected to the second outlet, the outlet end directly discharging water; and a control system, the control system being connected to the three-way valve 3 to control the selective opening of the first outlet and the second outlet.

[0016] like Figure 1As shown, the temperature sensor 6 is embedded in the bottom plate concrete 1, and is connected to the control system to control the opening and closing of the first outlet and the second outlet according to the temperature.

[0017] As shown, Figure 1 The cooling water pipe 4 is divided into at least two branches in the bottom plate concrete 1, and the branches are embedded in the bottom plate concrete 1 at different depths to cool the bottom plate concrete 1 at different depths.

[0018] As shown, Figure 1 Each branch corresponds to a temperature sensor 6 embedded in the bottom plate concrete at the corresponding depth, and the multiple temperature sensors 6 are connected to the control system. When any temperature sensor 6 detects that the temperature is too high, the temperature information is transmitted to the control system, and the control system opens the first outlet to flow water into the cooling water pipe 4.

[0019] In this embodiment, the cooling water pipe 4 is divided into two branches, and two temperature sensors 6 are embedded in the bottom plate concrete 1 correspondingly. In addition, a temperature sensor 6 is embedded in the shallow position of the bottom plate concrete 1 to detect the temperature of the shallow layer of the bottom plate concrete 1.

[0020] As shown, Figure 1 The water collecting well 7 is opened in the bottom plate concrete 1, and the drainage pipe and the cooling water pipe 4 both discharge water into the water collecting well 7.

[0021] In this embodiment, as shown, Figure 1 The second water pump is arranged in the water collecting well 7 to discharge water in the water collecting well 7.

[0022] As shown, Figure 1 The cooling water pipe 4 is made of metal.

[0023] In this embodiment, the cooling water pipe 4 is pre-embedded when the steel bars are bound in the bottom plate concrete during construction, and the temperature sensor 6 is arranged according to the requirements when the bottom plate concrete 1 is poured. After pouring, the control system is connected to the water pump 5, the water inlet pipe, the cooling water pipe 4, the drainage pipe, and the temperature sensor 6. During use, the control system can determine whether the bottom plate concrete 1 needs to be cooled according to the temperature data provided by the temperature sensor 6. If the bottom plate concrete 1 needs to be cooled, the control system controls the three-way valve 3 to make water flow through the cooling water pipe 4 reserved in the bottom plate concrete 1 to cool the bottom plate. If the temperature data provided by the temperature sensor 6 shows that the bottom plate concrete 1 does not need to be cooled, the control system controls the three-way valve 3 to directly discharge the underground water into the water collecting well 7.

[0024] It should be explained finally: above only is the preferred embodiment of the utility model and is not used for limiting the utility model, although the utility model has been explained in detail with reference to foregoing embodiment, for the skilled person in the art, it still can modify the technical scheme recorded in foregoing each embodiment or make equivalent replacement to part technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model should be contained in the protection scope of the utility model.
