Wherein, the water absorption and water retention layer can be water absorption resin, and the air-tight layer can be plastic cloth and the like.

As shown in fig. 1, 2-1 and 2-2, only two sub-coatings will be described as an example. The concrete curing device comprises a first sub-coating layer 1 and a second sub-coating layer 2. The two sub-coating layers have basically the same structure, wherein the first sub-coating layer 1 comprises a first water absorption and retention layer 11, an air-impermeable layer 12 and a first water pipe 13. Similarly, the second subcoating comprises a water-absorbing and water-retaining layer 21, an air-impermeable layer 22 and a second water pipe 23. The second water tube 23 is provided between the water-absorbing and-retaining layer 21 and the air-impermeable layer 22. A plurality of water outlet holes are formed in the first water pipe 13 and the second water pipe 23. For example, the first water pipe 13 is provided with a first water outlet hole 131, and the second water pipe 23 is provided with a second water outlet hole 231. Wherein, one end of the first water pipe 13 is provided with a first connector 132, the adjacent end of the second water pipe 23 is provided with a second connector 232, and the first water pipe 13 and the second water pipe 23 are communicated into a water pipe string through the first connector and the second connector. And, one end of the water pipe string is connected to the first water supply pump 40, and the other end of the water pipe string extends into the water reservoir 50. First working shaft 40 supplies water to water pipe cluster hole, and rivers flow to the guarantor's water layer of absorbing water from the apopore.

In fact, according to the concrete area requirement, more sheet cladding layers can be connected into a whole, each water pipe is communicated with the water pipe of the adjacent sub cladding layer, and one water pipe can be communicated with a plurality of adjacent water pipes as long as a water flow channel can be formed.

When the concrete curing device is used, the concrete curing device covers the concrete to be cured, and particularly, one surface of a water absorption and retention layer covers the concrete. The water from the reservoir 50 is pumped by the first water supply pump 40 into the water line 30 and returned to the reservoir 50 via the water line string. Meanwhile, water flows out of the water outlet holes of the water pipe string and is immersed in the water absorption and retention layers 11 and 21. Water is absorbed by each water absorption and retention layer to satisfy the humidity requirement of concrete curing, and the air-impermeable layer can avoid the evaporation of water too fast, so that the concrete curing environment is continuously maintained at the required humidity and temperature.

In an alternative embodiment, the sub-coatings are adhered together by a magic tape. Specifically, as shown in fig. 1, a strip-shaped hook surface 14 of the magic tape is provided along the edge of the first sub-coating 1, and a strip-shaped hair surface 24 of the magic tape is provided along the edge of the second sub-coating 2. When in use, the hook surface 14 of the magic tape and the hair surface 4 of the magic tape are stuck together, and the sub-coating layers can be connected into a piece.

Or, the water distributor may be shaped like a fishbone and comprises a main water pipe and a plurality of water distribution pipes extending from the main water pipe to two sides.

In an alternative embodiment, when the device is applied to inclined concrete, the lower part of the water-absorbing and water-retaining layer is easy to accumulate more water due to the self-weight of the water flow, and the upper part of the water-absorbing and water-retaining layer may be insufficient.

Also, the water tube string inner bore of the first water tube 13 extending into the water reservoir 50 is closed, so that only the branch tube 138 communicates with the second suction pump 70 through the water tube string inner bore. The first water supply pump 40 penetrates the first outer pipe from the side of the first water pipe 13 and communicates with the first annular space 100 to supply water into the first annular space 100.

To briefly explain the operation, the first water supply pump 40 supplies water into the first water pipe 13 through the first annular space 100, and the water flows from the first water supply pump 40 to the water reservoir 50 due to the closed first annular space of the branch pipe 138, and the water flows out of the first water outlet hole 131 and is soaked in the water-absorbing and water-retaining layer. The second suction pump 70 sucks the accumulated water in the accumulated water tank 150 through the inner hole of the water pipe string of the first inner pipe 133 and feeds the water into the water reservoir 50. Thereby guarantee that the upper portion and the lower part on the water absorption guarantor's guarantor layer can both evenly be full of water, and then guarantee that the humidity of concrete satisfies the maintenance demand.

The first water supply pump 40 communicates with the water supply passage 1431 to supply water into a space between the second inner pipe and the second outer pipe. And a pulley is further disposed on the outer wall of the second outer tube 141, and the belt 163 is driven by the motor 160 to rotate the second outer tube 141.

The motor 160 rotates the second outer pipe 141, and at the same time, the first water supply pump 40 supplies water to the annular space, and in case that the second outer pipe 141 rotates at a high speed, the water flows through the gap between the second annular protrusion 601 and the first annular protrusion 201, and the friction force generated by the high-speed rotation has an effect of heating the water. So that the water flow in the annulus becomes hot water. The water supply joint is connected to the first water pipe 13 such that the space between the annular groove and the annular boss communicates with the third annular space 300 through the through hole 146, and the inner hole of the water supply joint and the inner hole of the water pipe also communicate. Thereby allowing hot water to enter the third annular space 300 and flow from the outlet holes to the water-absorbing and water-retaining layer. When only cold water is required, then the motor 160 need not be rotated, and only cold water is pumped from the second water supply pump 161 into the inner bore of the water pipe, from where it enters the third annular space 300 through the outlet holes in the second inner pipe 142 and out the outlet holes in the second outer pipe 141.

The motor rotating speed can be connected with a temperature sensor on the surface of concrete, the temperature sensor sends the detected temperature to the control unit, and the control unit adjusts the motor rotating speed according to the temperature requirement. When the temperature of the concrete is detected to be low and hot water needs to be provided, the motor is started, and the water is heated and supplied through friction rotation. And if the temperature difference is large, increasing the rotating speed of the motor. When the detected temperature is higher than the requirement, the control unit stops the motor and controls the second water supply pump to supply water to the water pipe string. The rotating speed of the motor is controlled through the detected temperature value, so that the temperature of the generated hot water is matched with the required temperature. The first water supply pump and the second water supply pump can be controlled to supply water simultaneously, so that cold water and hot water are mixed to regulate the temperature of water sprayed out of the water pipe.
