Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a concrete winter maintenance device. Background Art

[0002] During the construction of a wind turbine, the wind turbine foundation is frustum-shaped. The wind turbine foundation belongs to a mass concrete foundation, including a circular bottom, a frustum-shaped middle part, and a circular top. The maintenance of the concrete foundation takes the longest time in the entire concrete construction project and is also the construction operation that has the greatest impact on the quality of the concrete. The reason why concrete can gradually harden and increase in strength is the result of the hydration of cement, and the hydration of cement requires certain temperature and humidity conditions. Therefore, concrete maintenance requires artificial creation of certain humidity and temperature conditions to enable the freshly poured concrete to harden and increase in strength normally or accelerate. In order to ensure the strength of the concrete and prevent cracks from occurring due to surface drying of the concrete, it is usually necessary to water the concrete to achieve the necessary humidity. If the watering and maintenance of the concrete are ignored, on the one hand, the strength of the concrete will decrease, and on the other hand, the concrete will not have time to replenish water during the hardening process, resulting in a large amount of water shortage and thus cracks. However, there are also conditions for watering and maintaining concrete. If the temperature is below 4 degrees Celsius, the concrete cannot be watered and maintained because the water evaporates relatively slowly at low temperatures, and even the water will turn into a solid and is not easy to evaporate and enter the concrete.

[0003] The invention patent with the patent number CN114656283B discloses a moisture and heat preservation device for winter maintenance of concrete, which includes a heat insulation pad, a heating pad, a composite functional water storage layer and an isolation layer distributed in sequence from top to bottom. The composite functional water storage layer is composed of a water-absorbing expanded rubber and a non-expanded water-absorbing sponge. A vertical pipe is provided on the isolation layer, and through holes for the vertical pipe to pass through are respectively formed in the heat insulation pad, the heating pad and the composite functional water storage layer. The top of the vertical pipe is provided with a water inlet for the water on the heat insulation pad to flow in, and the bottom of the vertical pipe is provided with a water injection port corresponding to the composite functional water storage layer. A plug is also provided at the top of the vertical pipe, and the plug is used to block the through hole on the heat insulation pad after the water-absorbing expanded rubber absorbs water and expands and pushes the heating pad and the heat insulation pad upward; during the watering process, the water body can enter the vertical pipe through the through hole on the heat insulation pad and the water inlet on the vertical pipe, and then enter the composite functional water storage layer through the water injection port for water storage. The water-absorbing expanded rubber in the composite functional water storage layer expands after absorbing water and can push the heating pad and the heat insulation pad above it upward, so that the through hole on the rising heat insulation pad is blocked by the plug at the upper end of the vertical pipe, completely isolating the heat and moisture preservation gap between the present invention and the concrete from the environment, avoiding the loss of water body and heat. On the one hand, it avoids the waste of water and heat resources, prolongs the interval between two watering maintenance operations, and reduces the labor intensity of workers; on the other hand, due to the isolation effect of the plug, the temperature and humidity in the heat and moisture preservation gap between the present invention and the concrete reach the standard, improving the maintenance effect of the concrete and ensuring the strength of the concrete after maintenance; during the solidification process of the concrete, the water in the concrete gradually evaporates, but in this patent, the water-absorbing expanded rubber expands after absorbing water and can push the heating pad and the heat insulation pad above it upward, so that the through hole on the rising heat insulation pad is blocked by the plug at the upper end of the vertical pipe, and the heat and moisture preservation gap between the concrete is completely isolated from the environment, avoiding the loss of water body and heat. Due to the closure of the heating pad and the heat insulation pad, the water body exists in the non-expanded water-absorbing sponge layer, making it difficult for the water in the concrete to evaporate or the evaporation time is longer, affecting the solidification of the concrete.

[0006] As a further improvement of the utility model, the concrete winter maintenance device includes a locking part, a paving part arranged at the lower end of the locking part, and a bottom sticking part arranged at the lower end of the paving part; the locking part and the bottom sticking part enclose to form a circular ring; the paving part encloses to form a frustum of a cone; the locking part, the paving part, and the bottom sticking part all include an isolation layer distributed successively from bottom to top, a water storage layer arranged on the isolation layer, a supporting cushion layer arranged on the water storage layer, and a heat insulation layer arranged on the supporting cushion layer.

[0008] As a further improvement of the utility model, sealing curtains are arranged on the side ends of the locking part, the paving part, and the bottom sticking part; the suspended ends of the sealing curtains are detachably connected to the locking part, the paving part, and the bottom sticking part respectively.

[0009] As a further improvement of the utility model, partition bars are arranged at intervals on the end surface of the shielding layer facing the water storage layer; water guiding soft strips are arranged on the partition bars.

[0010] The beneficial effects of the utility model are reflected in:

[0011] By arranging telescopic air bags to support the shielding layer, a spacing is formed between the shielding layer and the water storage layer to form an evaporation space.

[0030] For further information, seeFigure 1 On the end face of the barrier layer 302 facing the water storage layer 2, baffle bars 17 are arranged at intervals, and water guiding flexible strips 18 are arranged on the baffle bars 17.

[0031] Preferably, the barrier layer 302, the baffle bars 17, and the water guiding flexible strips 18 are all made of rubber material.

Under the heating of the heating net 5, the moisture evaporates into the evaporation space 6 and adheres to the barrier layer 302. As the moisture continuously gathers to form water droplets, the water droplets flow along the barrier layer 302, are blocked by the baffle bars 17 and flow down along the baffle bars 17 and the water guiding flexible strips 18. After the water droplets flow down, they enter the water absorption sponge 202 to keep the water content in the water absorption sponge 202, and further keep the humidity of the fan concrete surface. The heating of the heating net 5 causes the moisture in the water absorption sponge 202 and the fan concrete foundation to evaporate into the evaporation space 6, so that the moisture is discharged from the concrete foundation, which is beneficial to the solidification of the concrete foundation.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
