Description

Technical Field

[0001] This utility model relates to the field of engineering construction. More specifically, this utility model relates to a high-efficiency concrete curing device for pier columns. Background Technology

[0002] In the construction of bridges, buildings, and other engineering projects, the post-concrete curing of pier columns is a crucial process for ensuring their strength development and preventing surface cracking. Currently, the commonly used methods are manual, timed watering or laying geotextiles for moisture retention. These methods are not only labor-intensive and resource-intensive, but their curing effectiveness is also greatly affected by human factors, especially during hot seasons when rapid water evaporation easily leads to surface cracks due to insufficient moisturizing. To address these issues, some automated curing devices have emerged in the prior art, such as the solar-powered curing device for high pier tops disclosed in prior art document CN216194048U. This device uses solar energy to drive a water pump for spraying, saving manpower, but its system is complex, requiring a water pump, solar motor, sensors, and power supply system, resulting in high manufacturing costs. Furthermore, it cannot function properly without sunlight or in the event of equipment malfunction. In practical use, we have found that water loss due to evaporation is still significant, limiting its energy-saving effect. Therefore, there is an urgent need for a new type of concrete curing device for pier columns that does not rely on external energy, has a simple structure, better water-saving performance, and reliable operation. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency concrete curing device for pier columns. Apart from pumping water into the storage tank by a water truck, the device does not require external power and can achieve uniform, long-lasting, and water-saving automated curing by relying solely on gravity and capillary action.

[0004] The technical solution adopted by this utility model to solve this technical problem is: a high-efficiency concrete curing device for pier columns, including a water storage tank set on the top of the pier column and a curing covering layer wrapped around the outside of the pier column, wherein a drip irrigation valve is provided at the bottom of the water storage tank. The curing layer comprises, from the inside out, a capillary absorption layer and a waterproof and water-locking membrane layer; the waterproof and water-locking membrane layer has a fabric-membrane structure; the capillary absorption layer consists of a geotextile nonwoven fabric layer and a superabsorbent resin particle layer, wherein the superabsorbent resin particles are evenly distributed on one side of the surface of the geotextile nonwoven fabric layer and fixed to the geotextile nonwoven fabric layer with an adhesive; the geotextile nonwoven fabric layer is fixed around the perimeter of the fabric layer corresponding to the waterproof and water-locking membrane layer; and the superabsorbent resin particle layer is positioned facing the waterproof and water-locking membrane layer. The water distribution mechanism is connected to the drip irrigation valve to direct water to the outer perimeter of the top of the pier.

[0005] As a further embodiment of this utility model, the top of the water storage tank is provided with a sealing cover with a water inlet and a vent valve.

[0006] As a further aspect of this utility model, the health-preserving coating has matching connectors on both sides of its longitudinal edge.

[0007] As a further embodiment of this utility model, the longitudinal edges of the health-preserving coating are fixed with adhesive tape.

[0008] As a further embodiment of this utility model, the water distribution mechanism includes: A ring-shaped tube is provided around the side wall of the pier and close to the top of the pier, and the ring-shaped tube has several micro-holes. The hose connects to the ring-shaped tube and the drip valve.

[0009] A further embodiment of this utility model is: it also includes a water-guiding core, the upper end of which extends into the annular pipe body from above, and the lower end of which extends and is buried between the pier and the curing cover.

[0010] This utility model has at least the following beneficial effects: This invention completely eliminates electrical components such as water pumps, motors, and sensors, relying solely on the gravitational potential energy of water and the capillary action of materials to achieve automatic drip irrigation and water diffusion. It fundamentally eliminates dependence on electricity, has a simple system structure, no fault points, and is extremely stable and reliable in operation, making it suitable for any construction environment.

[0011] By employing a combination of a sandwich-type capillary absorption layer and a waterproof and water-locking membrane layer, a closed, moisture-retaining environment is created. Moisture is absorbed by the superabsorbent resin and slowly released to the concrete surface, while the waterproof and water-locking membrane prevents evaporation loss, significantly extending the curing time for each water application and resulting in water resource utilization far exceeding that of traditional spraying methods.

[0012] Easy installation and low cost: The core of the device is a water storage tank and a composite curing coating. The installation and disassembly process does not require professional tools or personnel. The operation is simple and quick, and the reusability is high, which greatly reduces the overall maintenance cost.

Those skilled in the art will be able to implement the present invention based on these descriptions. Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0017] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, and the specific implementation process is as follows: like Figure 1 As shown, this utility model provides a high-efficiency concrete curing device for pier columns, including a water storage tank 2 set on the top of the pier column 1 and a curing covering layer 3 wrapped around the outside of the pier column 1. The water storage tank 2 is a PE plastic water tank with a sealable top and a drip valve 4 at the bottom. The drip valve 4 is a manually adjustable rotary water-saving valve. The protective covering layer 3 comprises, from the inside out, a capillary absorption layer and a waterproof and water-locking membrane layer 5. The waterproof and water-locking membrane layer 5 has a fabric-membrane structure, which is a geosynthetic material made by calendering or hot-melt bonding geotextile and a polymer membrane. The capillary absorption layer consists of a geotextile nonwoven fabric layer 7 and a superabsorbent resin particle layer 6, wherein the superabsorbent resin particles are evenly distributed on one side of the surface of the geotextile nonwoven fabric layer 7 and fixed to the geotextile nonwoven fabric layer 7 with an adhesive. The geotextile nonwoven fabric layer 7 is surrounded by a waterproof and water-locking membrane layer. The fabric layer corresponding to the water film layer 5 is fixed around its perimeter. The superabsorbent resin particle layer 6 is positioned facing the waterproof and water-locking membrane layer 5, and the geotextile nonwoven fabric faces the pier column 1 side, thereby protecting the superabsorbent resin particle layer 6. The geotextile nonwoven fabric layer 7 and the waterproof and water-locking membrane layer 5 can be fixed around their perimeter by hot pressing, or the upper and lower edges of the geotextile nonwoven fabric layer 7 and the waterproof and water-locking membrane layer 5 can be sealed and connected by waterproof adhesive tape. The final waterproof and water-locking membrane layer 5 is an integral structure similar to a roll material, which is convenient for on-site storage and transportation. The water distribution mechanism is connected to the drip irrigation valve 4 to divert water to the outer perimeter of the top of the pier column 1.

[0019] In another technical solution, the top of the water storage tank 2 is equipped with a sealing cover 8 with a water inlet and a vent valve. A long water pipe 9 is connected to the water inlet and is lowered to the ground. Water is added to the water storage tank 2 by a water truck. The bottom of the water storage tank 2 is a conical or sloping bottom structure. The entire tank is supported by a bracket, so that the bottom of the tank is a certain distance from the top of the pier 1. The outside of the water storage tank 2 is equipped with a transparent PE plastic liquid level observation window for easy observation of the water level.

[0020] In another technical solution, the curing cladding layer 3 has matching connectors on both sides of its longitudinal (i.e., height) side. In this embodiment, the connectors are long strip-shaped Velcro or waterproof zippers. The construction workers wrap the open side of the curing cladding layer 3 around the pier 1, and then close it with Velcro or zippers to form a cladding layer that tightly wraps around the pier 1.

[0021] In another technical solution, the two longitudinal edges of the curing layer 3 are fixed with tape, and tape is spaced along the height direction. The tape is wrapped around the outer periphery of the curing layer 3 in the circumferential direction, which can further secure the curing layer 3 to the pier 1.

[0022] In another technical solution, the water distribution mechanism includes: A ring-shaped pipe 10 is installed around the side wall of the pier 1 and close to the top of the pier 1. The ring-shaped pipe 10 has several micro-holes 11 for water seepage. The ring-shaped pipe can be connected and fixed to the steel bars at the top of the pier 1 by rope. The curing cover 3 covers the ring-shaped pipe 10 inside it. The top length of the curing cover 3 is higher than the top of the pier 1. It can be fixed by wrapping a ring of tape around the steel bars at the top of the pier 1. The hose 13 is connected to the annular tube 10 and the drip valve 4.

[0023] In another technical solution, a water-guiding core 12 is also included. The water-guiding core 12 is a cotton rope or nylon rope core, with its upper end extending into the annular tube 10 from above, and its lower end extending and buried between the pier 1 and the curing covering layer 3. In this embodiment, an opening is provided at the top of the annular tube 10, and a silicone plug 14 is provided at the opening. The silicone plug 14 has an opening with a diameter only large enough for the water-guiding core 12 to pass through. The water-guiding core 12 extends into the annular tube 10. When water flows through the annular tube 10, the water-guiding core 12 is immersed in the water in the annular tube 10. There can be multiple water-guiding cores 12, evenly distributed around the pier 1. Through the water-guiding core 12, water diffuses evenly within it and simultaneously wets the capillary permeation layer of the entire annular area it contacts. The water then relies on the adsorption and diffusion capacity of the capillary infiltration layer to evenly wet the entire surface of the pier 1 from top to bottom, thereby achieving full-coverage curing. The length of the water-guiding core 12 can be adjusted as needed. In this embodiment, the water-guiding core 12 extends downward to the upper part of the side of the pier 1, without exceeding the middle of the pier 1.
