DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0023] Reference Figure 1 As shown, this embodiment discloses a large-volume concrete cooling and curing device. Specifically, the large-volume concrete cooling and curing device includes: a cooling water pool 2 and at least two groups of cooling and curing units arranged at intervals along the width direction of the concrete 1; each group of cooling and curing units includes a cooling water inlet pipe 4, multiple cooling water pre-buried pipe sections 5, a cooling water outlet pipe 8, a water pump 3 and a spray curing device; the middle parts of the multiple cooling water pre-buried pipe sections 5 are all pre-buried in the concrete 1, and the multiple cooling water pre-buried pipe sections 5 are arranged in parallel and at intervals along the height direction of the concrete 1, and both ends of each cooling water pre-buried pipe section 5 are located outside the concrete 1, and the multiple cooling water pre-buried pipe sections 5 are sequentially connected end to end through connecting elbows 6 to connect the cooling water pre-buried pipe sections 5 in series to form a cooling and cooling pipeline (because the cooling water pre-buried pipe sections 5 Both ends are located on the outside of the concrete 1, so the connecting pipe 6 must be located on the outside of the concrete. The cooling and cooling pipe is roughly square wave-shaped, that is, the upper and lower adjacent connecting bends 6 are respectively arranged on both sides of the concrete 1), and both ends of the connecting bend 6 are connected to the cooling water pre-buried pipe section 5 through a movable joint 7; the water inlet end of the cooling water pre-buried pipe section 5 located at the bottom is connected to the water outlet end of the cooling water inlet pipe 4 through a movable joint 7, and the water inlet end of the cooling water inlet pipe 4 is connected to the cooling water pool 2 through a water pump 3; the water outlet end of the cooling water pre-buried pipe section 5 located on the uppermost side is connected to the water inlet end of the cooling water outlet pipe 8 through a movable joint 7, and the water outlet end of the cooling water outlet pipe 8 is connected to the cooling water pool 2; the spray curing device is connected to the connecting bend 6 located on the uppermost side, and the connecting bend 6 is U-shaped.

[0024] In the large volume concrete cooling and curing device of this embodiment, when in use, the water pump 3 draws water from the cooling water pool 2 into the cooling and cooling pipe formed by connecting a plurality of cooling water pre-buried pipe sections 5 in series (the water pump 3 draws water from the cooling water pool 2 into the large volume concrete 1 for circulation, taking away the internal heat of the concrete 1 to achieve the cooling effect). Since the cooling water pre-buried pipe sections 5 are connected together by connecting elbows 6, and the connecting elbows 6 and the cooling water pre-buried pipe sections 5 are connected by movable joints 7, when one of the cooling water pre-buried pipe sections 5 has a problem, the remaining cooling water pre-buried pipe sections 5 can still be The circulation is connected, thereby effectively solving the problem of the integral cooling pipe being scrapped due to blockage. At the same time, a maintenance spray device is added to the connecting elbow 6 located on the uppermost side. The maintenance spray device can not only realize semi-automatic maintenance but also make the temperature of the maintenance water consistent with the internal temperature of the concrete 1, which is more conducive to the molding of the concrete 1 and avoids temperature cracks caused by the temperature difference between the inside and the outside. In addition, the water that takes away the internal temperature of the large volume of concrete 1 can be used for maintenance and can also be returned to the cooling water pool 2 to form a circulation, thereby solving various practical traditional cooling disadvantages and meeting the construction use requirements.

[0025] Specifically, the above-mentioned spray curing device includes a valve 8, a spray pipe 10 and a nozzle 11; the spray pipe 10 is connected to the uppermost connecting elbow 6 through the valve 8, and the nozzle 11 is connected to the end of the spray pipe 10 away from the connecting elbow 6. The spray pipe 10 is arc-shaped, and the nozzle 11 is arranged directly above the concrete 1. The nozzles 11 of at least two groups of cooling curing units are staggered to make the area covered by the nozzles 11 larger, so that the curing of the concrete 1 is more uniform.

The cooling water pre-buried pipe section 5, the cooling water inlet pipe 4 and the cooling water outlet pipe 8 are DN32 PVC pipes, and the spray pipe 10 is a DN16 PVC pipe.

[0027] In this embodiment, both ends of the movable joint 7 are connected to the pipeline by threads to facilitate disassembly.

[0028] It should be noted that the area of the cooling water pool 2 needs to meet the heat dissipation and water supply and withdrawal requirements.

[0029] Specifically, the assembly and operation process of the above-mentioned large-volume concrete cooling and curing device is as follows:

[0030] First, when supporting the formwork for the mass concrete, pre-buried cooling water pipe sections are embedded in sections and arranged within the formwork to complete the pouring of the mass concrete. Then, multiple connecting elbows and flexible joints are used on the outside to connect the multiple pre-buried cooling water pipe sections to form an integrated cooling and cooling pipeline. A valve is then added to the uppermost connecting elbow, and external spray pipes and nozzles are installed to enable automatic maintenance. The specific operation process is that a water pump draws water from the cooling water tank through the cooling and cooling pipeline into the mass concrete. The water flows through the mass concrete, removing the internal heat. The spray device installed at the top can perform maintenance, and the remaining water returns to the cooling water tank for natural cooling, thus completing the cycle.
