Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building rafts, in particular to a cooling device for a raft foundation. Background Art
[0002] The construction of large-volume concrete raft foundations is usually a difficult and key point in construction. However, due to unreasonable steel support settings and inadequate concrete temperature control measures, it will cause the overall collapse of the steel bars and a large number of cracks in the concrete, ultimately causing major safety and quality accidents.
[0003] The Chinese utility model patent with publication number CN214940322U, published on November 30, 2021, discloses a cooling structure for large-volume concrete in raft foundations. After the raft concrete surface layer is poured, the seal on the top of the vertical pole is removed, so that the hydration heat in the center of the raft concrete is dissipated from the vertical pole. However, since the space inside the vertical pole is not conducive to air circulation, and only the central hydration heat of the valve plate can be locally dissipated through the vertical pole, the heat dissipation effect is not ideal. Utility Model Content
[0004] In response to the above problems, the utility model provides a cooling device for a raft foundation, which uses an outlet pipe to transport cooling water in the pool to the heat exchange tube. The cooling water flowing in the heat exchange tube removes the hydration heat and flows back to the pool through the water inlet pipe, performing water circulation to dissipate heat, thereby improving the heat dissipation effect.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0024] like Figures 1-6As shown, the cooling device for the raft foundation of this embodiment includes a raft body 1, a heat exchange pipe 5, a water pool 7, a water outlet pipe 8, a water inlet pipe 9 and a cooling bellows 12. The heat exchange pipe 5 is fixed inside the raft body 1, and the inlet end of the heat exchange pipe 5 is connected to the outlet of the circulation pump 10 through a two-way joint 6, the inlet of the circulation pump 10 is connected to the outlet of the water outlet pipe 8, and the inlet of the water outlet pipe 8 is connected to the outlet of the water pool 7; the inlet of the water pool 7 is connected to the outlet of the heat exchange pipe 5 through the water inlet pipe 9; the cooling bellows 12 is fixed to the top of the water pool 7, and a fan 13 is provided on the side wall of the cooling bellows 12. The inner end of the fan 13 is connected to the cavity inside the cooling bellows 12, and an air outlet 14 is provided at the bottom of the cooling bellows 12.
[0025] The utility model uses the outlet pipe 8 to transport the cooling water in the water pool 7 to the heat exchange pipe 5. The cooling water flowing in the heat exchange pipe 5 removes the hydration heat and returns to the water pool 7 through the water inlet pipe 9, performing water circulation and heat dissipation, thereby improving the heat dissipation effect. The fan 13 draws air into the cooling air box 12 and discharges it through the air outlet 14, thereby cooling the cooling water in the water pool 7 and improving the cooling effect of the central hydration heat of the raft body 1.
[0026] Furthermore, a cushion layer 2 is fixed to the bottom of the raft body 1 .
[0027] The cushion layer 2 protects the raft body 1 .
[0028] Furthermore, an upper steel frame 3 is fixed to the upper end of the raft body 1 , and a lower steel frame 4 is fixed to the lower end of the raft body 1 .
[0029] The upper steel frame 3 and the lower steel frame 4 can increase the structural strength of the raft body 1 .
[0030] Furthermore, the heat exchange tubes 5 are continuously arranged in a U-shape inside the raft body 1 .
[0031] The U-shaped continuous structure can effectively increase the heat exchange area and enhance the heat dissipation effect.
[0032] Furthermore, a digital temperature sensor 11 is fixed to the outer periphery of the water inlet pipe 9 .
[0033] The water temperature is monitored by a digital temperature sensor 11 and the water circulation is stopped until the water temperature is maintained within a constant range.
[0034] Furthermore, a water supply pipe 15 is provided at the top of the side wall of the pool 7, and a drainage pipe 16 is provided at the bottom of the side wall of the pool 7.
[0035] The water supply pipe 15 and the drain pipe 16 facilitate the addition or discharge of cooling water in the pool 7 .
[0036] The method of using the utility model is as follows:
[0037] After the raft body 1 is poured with concrete, the hydration heat inside the raft body 1 is transferred to the heat exchange tube 5. By starting the circulation pump 10, the cooling water in the pool 7 is transported to the heat exchange tube 5 through the outlet pipe 8. The inner side of the heat exchange tube 5 utilizes the circulation of cooling water, and the hydration heat is discharged by the cooling water flowing in the heat exchange tube 5. The cooling water is then returned to the pool 7 through the inlet pipe 9, and water circulation heat dissipation is performed. In addition, the heat exchange tube 5 is continuously arranged in a continuous U-shaped structure on the inner side of the raft body 1, thereby effectively increasing the heat exchange area.
[0038] The water temperature is monitored by the digital temperature sensor 11, and the water circulation is stopped until the water temperature is maintained within a constant range;
[0039] The protruding heat exchange tubes 5 do not need to be cut off. Before constructing the decoration surface layer, it is only necessary to fill the inside of the steel heat exchange tubes 5 tightly with cement mortar.
