Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, in particular to a concrete curing blanket. Background Art

[0002] After pouring large volumes of concrete, a 28-day curing period is generally required. This curing is achieved by sprinkling water on the poured concrete surface or covering it with a geotextile and then sprinkling water on the geotextile to keep it moist. Generally, in engineering projects, dedicated personnel are assigned to water the concrete surface for curing. However, when dealing with large volumes of concrete like dams, the concrete is exposed to the air. If personnel fail to water it in time due to negligence, the quality of the concrete cannot be guaranteed, resulting in problems such as cracks on the concrete surface.

[0003] In order to solve the problem of untimely maintenance due to insufficient staffing or negligence of personnel, a water pipe is usually installed on the construction site to continuously flow water to maintain the concrete. However, the continuous water flow maintenance method cannot fully cover all concrete surfaces, which often causes sewage to flow across the entire working surface. The uneven maintenance area makes it impossible to maintain the required location. At the same time, this method will result in a large water fee expenditure and a poor image of safe and civilized construction on site. Summary of the Invention

[0004] The purpose of the present invention is to provide a concrete curing blanket which can keep the curing blanket moist for a long time and can be used to cure large volumes of concrete.

[0006] Furthermore, the serpentine loop pipe is a U-shaped pipe structure that bends and circles sequentially inside the blanket body.

[0007] Furthermore, the diameter of the serpentine loop tube is 5 mm, and the diameter of the micro-spray hole is 1 mm.

[0008] Furthermore, the spacing between the micro spray holes is 2 cm.

[0026] like Figure 1-Figure 3 As shown,

[0027] A concrete curing blanket comprises a blanket body 1, wherein a serpentine loop pipe 2 is provided inside the blanket body 1. The serpentine loop pipe 2 is a U-shaped pipe structure that bends and circles in sequence inside the blanket body 1. A water inlet joint 3 and a water outlet joint 4 are fixed at diagonal positions at both ends of the blanket body 1, and the two ends of the serpentine loop pipe 2 are connected to the water inlet joint 3 and the water outlet joint 4, respectively.

[0028] In this embodiment, the diameter of the serpentine loop tube 2 is 5 mm, and a plurality of micro-spray holes 5 with a diameter of 1 mm are evenly arranged on the serpentine loop tube 2. In this embodiment, the spacing between the micro-spray holes 5 is 2 cm.

[0029] When in use, water flows into the serpentine loop pipe 2 through the water inlet joint 3 and is sprayed out from the micro-spray holes 5 on the serpentine loop pipe 2, which can keep the curing blanket moist for a long time, thereby curing the concrete.

[0030] In this embodiment, a guide bag 6 for inserting the serpentine loop tube 2 is sewn or pressed on the blanket body 1 . The serpentine loop tube 2 is positioned by the guide bag 6 so that the serpentine loop tube 2 can be stably fixed in the blanket body 1 .

[0031] The blanket body 1 comprises a surface plastic film 101, a middle layer of superabsorbent fiber felt 102, and a bottom layer of non-woven polyester fabric 103. These layers are bonded together using a moisture-resistant hot-melt adhesive. In this embodiment, the blanket body 1 is 1.8 meters long and 1.5 meters wide. The guide bag 6 is sewn between the middle layer of superabsorbent fiber felt 102 and the bottom layer of non-woven polyester fabric 103.

[0032] A plurality of connecting holes 7 are evenly arranged around the blanket body 1 . When multiple blanket bodies 1 are spliced ​​together for use, the upper and lower or left and right adjacent blanket bodies 1 can be connected together through the connecting holes 7 by means of positioning rings 8 .

[0033] When using a combination of upper and lower blankets 1, the outlet connector 4 of the upper blanket 1 is connected to the inlet connector 3 of the lower blanket 1, thereby achieving water connectivity between the multiple blankets and enabling the serpentine loop pipes 2 between the blankets to be used in series. The outlet connector 4 of the lowermost blanket is closed with a water-stop nut, maintaining a certain water pressure within the serpentine loop pipe 2, ensuring that water is constantly sprayed out of the micro-spray holes 5.

[0034] When the present invention is in use, the serpentine loop pipe 2 passes through the guide bag 6 on the blanket body 1 and is evenly arranged inside the blanket body 1. The serpentine loop pipe 2 is arranged in a serpentine shape inside the blanket body 1, and the two ends of the serpentine loop pipe 2 are respectively connected to the water inlet joint 3 and the water outlet joint 4 of the blanket body 1.

[0035] Adjacent blankets 1, either vertically or horizontally, are joined together through connection holes 7 using positioning rings 8. The water outlet connector 4 of the upper blanket 1 is connected to the water inlet connector 3 of the lower blanket 1. The water outlet connector 4 of the lower blanket is closed with a water-stop nut. The water inlet connector 3 of the uppermost blanket 1 is connected to an external water pipe. Water in the pipe is sprayed through micro-spray holes 5 in the serpentine loop pipe 2, keeping the curing blanket moist for a long time and curing the concrete.

[0036] The blanket bodies of the present invention can be connected to each other through positioning rings for combined use, the serpentine loop pipes between the blanket bodies can be connected in series, and water is sprayed through the micro-spray holes on the serpentine loop pipes to keep the curing blanket moist for a long time, so that a large volume of concrete can be cured.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
