Description

Technical Field

[0001] This utility model relates to the field of concrete segment curing technology, specifically a precast concrete segment curing system based on carbon dioxide neutralization. Background Technology

[0002] The carbon dioxide neutralization-based precast concrete segment curing system is a system that utilizes the mineralization reaction between carbon dioxide and components in concrete to achieve the curing of precast concrete segments.

[0003] Precast concrete segments need to be cured by immersion in water, but the water tends to become alkaline after a period of time, forming wastewater that is currently discharged directly, which is wasteful. Carbon dioxide is produced using carbon dioxide gas production equipment and injected into the water. This carbon dioxide reacts with the cementitious components and other alkaline calcium and magnesium components in the pre-cured or early-hydrated concrete, forming carbonate products in the concrete's internal pores and interfacial structures. Through filling effects, interfacial transition zone elimination effects, and product layer effects, the strength and durability of the concrete are improved.

[0004] However, calcium carbonate is a sparingly soluble salt that tends to gradually deposit in the circulation system of the curing tank. When cleaning is not carried out on a fixed schedule and is done arbitrarily, calcium carbonate is not removed in a timely manner. As the amount of deposits increases, calcium carbonate continues to accumulate at the bottom of the curing tank, reducing the effective water depth at the bottom of the tank. The originally designed water depth can no longer meet the curing requirements. At the same time, the bottom of the tank becomes uneven, changing the original physical structure. In such an environment, the concrete segments cannot fully contact the curing water, affecting the service strength of the concrete segments. Utility Model Content

Detailed Implementation

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0038] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0039] Example 1, referring to Figures 1-3 and Figure 7 This is the first embodiment of the present invention, which provides a precast concrete segment curing system based on carbon dioxide neutralization. The device includes a curing structure 100, including a curing pool wall 101.

[0040] The support structure 200 includes a plurality of mounting grooves 201 formed on the surface of the curing pool wall 101, and support rods 202 installed inside the mounting grooves 201; and,

[0041] The mounting groove 201 facilitates the installation of the support rod 202 on the wall 101 of the curing pool. The horizontal plane of the support rod 202 is above the connecting seat 3045, so it will not affect the movement of the connecting seat 3045. The support rod 202 is made of corrosion-resistant material.

[0042] By placing the precast concrete segments on the corrosion-resistant support rods 202 on the side wall of the curing pool, the segments are prevented from contacting the bottom of the pool. This effectively prevents the uneven deposition of calcium carbonate at the bottom of the pool from affecting the full contact between the segments and the curing water, thus ensuring the strength of the concrete segments.

[0043] The scraping structure 300 includes a mounting base plate 301 fixed to the wall 101 of the curing tank, a fixing plate 302 fixed to the mounting base plate 301, a first support plate 3035 fixed to the fixing plate 302, a power assembly 303 rotating on the surface of the first support plate 3035, a scraping assembly 304 rotating on the power assembly 303, and an auxiliary assembly 306 fixed to the power assembly 303. The mounting base plate 301 is fixed to the surface of the curing tank wall 101 by bolts. The support plate is used to fix and support the power assembly 303, the scraping assembly 304, and the auxiliary assembly 306. The power assembly 303 provides power for the operation of the scraping assembly 304 and the auxiliary assembly 306. The scraping assembly 304 is used to scrape and clean the calcium carbonate precipitate at the bottom of the curing tank, and the auxiliary assembly 306 is used to provide additional traction force to the scraping assembly 304.

[0044] The power assembly 303 includes a timer motor 3031 rotating on a first support plate 3035, and a bolt column 3032 fixed to one end of the timer motor 3031. The timer motor 3031 can be turned on and off at set times, and can rotate forward and reverse during operation. The working principle of this part is existing technology and can be clearly understood by those skilled in the art, so it will not be described in detail here. This drives the rotation of the bolt column 3032.

[0045] A guide groove 3033 is provided on the surface of the fixing plate 302, and a sliding groove 3034 is provided on the surface of the fixing plate 302 and on the side of the guide groove 3033. The guide groove 3033 facilitates the connecting rod 3044 to pass through the fixing plate 302 to reach the bottom of the curing tank, and the sliding groove 3034 provides space for the sliding of the positioning block 3043.

[0046] The scraping assembly 304 includes a movable base 3041 rotatable on the surface of the bolt post 3032, a bolt groove 3042 formed on the surface of the movable base 3041, a positioning block 3043 fixed to the lower surface of the movable base 3041, and a connecting rod 3044 fixed to the lower surface of the movable base 3041. The bolt post 3032 passes through the bolt groove 3042, driving the movable base 3041 to reciprocate on the slide groove 3034. The positioning block 3043 is used to limit and fix the position of the movable base 3041 in the direction of movement, preventing the movable base 3041 from shifting its position due to water resistance during movement, thereby avoiding affecting the movement of the connecting base.

[0047] The connecting rod 3044 has a connecting seat 3045 fixed to its top end. A rake plate 3046 is fixedly connected to the surface of the connecting seat 3045. A scraper 3047 is fixed to the surface of the connecting seat 3045 and to the side of the rake plate 3046. A groove 3047-1 is formed on the surface of the scraper 3047. During the movement of the rake plate 3046 and the scraper 3047, the rake plate 3046 damages the surface of the sediment, and the scraper 3047 scrapes away the damaged sediment. The groove 3047-1 prevents the scraper 3047 from being too smooth, which would cause the sediment to slip and fall during the scraping process. This ensures that the sediment can be stably pushed to the collection area, effectively improving the cleaning effect and efficiency, ensuring the cleanliness of the bottom of the curing tank, and creating a good curing environment for the precast concrete segments.

[0048] The edges of the groove 3047-1 are chamfered to prevent sediment from accumulating and remaining in the groove 3047-1, thus avoiding blockage caused by long-term accumulation and affecting the cleaning efficiency of the scraper 3047. At the same time, the chamfered design can reduce the frictional resistance between the scraper 3047 and the sediment, making the scraper 3047 move more smoothly during reciprocating motion.

[0049] During use, at the deep water point of the curing tank, a row of linearly arranged support rods 202 are installed on the side wall of the curing tank. There is an equidistant gap between adjacent support rods 202. These support rods 202 are made of corrosion-resistant material. Precast concrete segments are placed on these support rods 202 to prevent contact between the segments and the bottom of the curing tank. Then, sediment on the surface of the curing tank is scraped off using a scraping component 304. The power to the timer motor 3031 is turned on, and the operating time interval of the timer motor 3031 is set. This part of the working principle is based on existing technology. As will be clearly understood by those skilled in the art, and without further explanation, the forward rotation of the timing motor 3031 drives the movable base 3041 on the screw surface to move, thereby driving the connecting seat 3045 at one end of the connecting rod to move. During the movement of the connecting seat 3045, the rake plate 3046 and the scraper plate 3047 are driven by the rake plate 3046 to break the surface of the sediment, and the scraper plate 3047 scrapes away and cleans the broken sediment. The reverse rotation of the timing motor 3031 drives the connecting seat 3045 to return to its initial state. In this process, the rake plate 3046 and the scraper plate 3047 remove the sediment in opposite directions.

[0050] By placing precast concrete segments on corrosion-resistant support rods 202 on the sidewall of the curing tank, contact between the segments and the tank bottom is avoided. This prevents uneven calcium carbonate deposits at the bottom from affecting the segments' contact with the curing water, ensuring the structural strength of the concrete segments. Simultaneously, a mechanical structure consisting of a timer motor 3031, a drive screw, a scraper 3047, and a tank rake automatically cleans the surface sediment of the curing tank at regular intervals, eliminating the need for haphazard manual cleaning. This timely removal of calcium carbonate deposits prevents a reduction in the effective water depth at the bottom of the tank, maintaining the original designed physical structure and water depth conditions of the curing tank, ensuring a stable curing environment, and improving the curing effect.

[0051] Example 2, refer to Figures 1-8 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the auxiliary component 306 includes an anti-detachment plate 3061 fixed to the top of the bolt post 3032, and a first bevel gear 3062 fixed to the surface of the anti-detachment plate 3061. The anti-detachment plate 3061 ensures the stable and secure rotation of the bolt post 3032 and also drives the rotation of the first bevel gear 3062, transmitting the power of the bolt post 3032 to the second bevel gear 3063.

[0052] Compared to Embodiment 1, the surface of the first bevel gear 3062 is further engaged with a second bevel gear 3063, the surface of the second bevel gear 3063 is fixed with a fixed shaft 3064, and the surface of the fixing plate 302 is fixed with a second support plate 3065. The fixed shaft 3064 rotates on the second support plate 3065. Both the second support plate 3065 and the fixed shaft 3064 are for fixing and supporting the fixed shaft 3064 to rotate under the drive of the second bevel gear 3063. The second bevel gear 3063 drives the rotation of the fixed shaft 3064, which in turn drives the rotating wheels 3067 at both ends of the fixed shaft 3064 to rotate.

[0053] Furthermore, rotating wheels 3067 are fixed at both ends of the fixed shaft 3064, and a guide hole 3068 is opened on the side of the second support plate 3065. A pull rope 3069 rotates on the surface of the rotating wheel 3067, and one end of the pull rope 3069 is fixed to the surface of the positioning block 3043.

[0054] One end of the pull rope 3069 passes through the guide hole 3068 and enters the slide groove 3034 to connect with the slider. The rotation of the wheel 3067 drives the pull rope 3069 to move, thereby generating a traction force on the slider. This enables the slider to reduce external interference factors such as frictional resistance and move smoothly and orderly to the designated position in the slide groove 3034. This ensures that the slider and the moving base 3041 achieve mechanical linkage, maintains the coordination of the entire moving base 3041 when moving against water resistance, and improves the working efficiency of the entire scraping assembly 304.

[0055] The remaining structure is the same as that in Example 1.

[0056] Example 3, referring to Figures 1-9 This is the third embodiment of the present invention, which differs from the second embodiment in that it further includes:

[0057] The collection structure 400 includes a first collection box 401 fixed to the surface of the wall 101 of the maintenance pool, a balance pipe 402 fixed to the surface of the first collection box 401, and a second collection box 403 fixed to one end of the balance pipe 402.

[0058] Compared to Embodiment 2, furthermore, the surface of the curing pool wall 101 and the locations of the symmetrical positions are provided with discharge troughs 1011, which are in the shape of right trapezoids.

[0059] The surfaces of the first collection box 401 and the second collection box 403 are respectively provided with inclined grooves corresponding to the discharge trough 1011. These inclined grooves are opened during the manufacturing process of the first collection box 401 and the second collection box 403. The working principle of this part is existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. The inclined surface of the right trapezoid of the discharge trough 1011 and the inclined surface of the inclined groove are in contact, which facilitates the sediment to enter the first collection box 401 and the second collection box 403 along the discharge trough 1011 and the inclined groove.

[0060] When the timer motor 3031 drives the bolt column 3032 to rotate forward, the rake plate 3046 breaks up the sediment, and the scraper 3047 discharges the sediment along the bottom of the curing tank through the discharge chute 1011 on the side of the curing tank into the first collection box 401, awaiting further processing. When the timer motor 3031 drives the screw to rotate in reverse and reset, the scraper 3047 and the rake plate 3046 discharge the sediment along the bottom of the curing tank in the opposite direction through the discharge chute 1011 on the other side of the curing tank into the first collection box 401, awaiting further processing.

[0061] The sediment is discharged into the first collection box 401 and the second collection box 403 through the inclined holes on the side of the curing tank, which facilitates centralized subsequent treatment, reduces the workload and difficulty of manual cleaning, and improves the reliability and efficiency of the curing system.

[0062] The balancing pipe 402 is designed to achieve pressure and water flow balance between the first collection tank 401 and the second collection tank 403. During the sediment collection process, when the sediment enters the first collection tank 401 and the second collection tank 403 through the discharge trough 1011, the balancing pipe 402 can balance the water level and pressure in the two tanks, preventing water flow disturbance caused by water level difference or pressure difference, thereby ensuring that the sediment can stably slide into the collection tank along the discharge trough 1011 and the inclined trough.

[0063] Specifically, when the sediment is pushed into the discharge trough 1011 by the scraper 3047 and enters the first collection tank 401 or the second collection tank 403 along the inclined chute, the balancing pipe 402 allows a small amount of water exchange between the two collection tanks. This exchange can prevent water level rise or pressure change caused by the increase of sediment on one side, thereby maintaining the stability of the entire collection system. Through this balancing mechanism, the sediment collection process can be ensured to proceed smoothly, avoiding the negative impact of violent fluctuations in water flow on sediment collection efficiency. At the same time, it also helps to reduce the agitation of the water in the curing tank and ensure the relative stability of the concrete segment curing environment.

[0064] Furthermore, a curing pool base 102 is fixed to the bottom of the curing pool wall 101, a water exchange pipe 1021 is fixed to the surface of the curing pool base 102, and a pad 103 is fixed to the surface of the curing pool base 102. The water exchange pipe 1021 can be used to replace the water in the curing pool, ensuring the quality and performance of the curing water. The pad 103 can further improve the stability of the curing pool, preventing the curing pool from tilting or shaking due to uneven ground or other external forces, ensuring the stability of the curing environment. On the other hand, it can create a height difference between the curing pool and the first collection tank 401 and the second collection tank 403, facilitating the entry of sediment into the first collection tank 401 and the second collection tank 403.

[0065] Furthermore, a transmission pipe 501 is fixed to the surface of the curing tank wall 101, a storage tank 502 is fixed to the top of the transmission pipe 501, and a valve 503 is installed on the surface of the transmission pipe 501. The storage tank 502 can be used to store carbon dioxide, and the transmission pipe 501 is the channel for transporting the carbon dioxide in the storage tank 502 to the curing tank. The valve 503 is used to control the opening and closing of the transmission pipe 501 and to regulate the flow rate and speed of the material.

[0066] The remaining structure is the same as that in Example 2.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
