Description

Technical Field

[0001] This invention belongs to the technical field of concrete component curing, specifically, it relates to a precision temperature control curing system for large-volume concrete. Background Technology

[0002] Currently, the heat of hydration in large-volume concrete is concentrated, and its internal temperature rises rapidly. A large temperature difference between the inside and outside of the concrete can cause temperature cracks, affecting its strength. Existing methods for controlling concrete temperature on construction sites mainly involve covering the outer surface of large-volume concrete with a thin film, geotextile, or insulation blanket. This requires a large amount of manual labor, is inefficient, and yields poor temperature control.

[0003] The existing technology, disclosed in CN111441588B and entitled "Intelligent Curing System and Method for Large-Volume Concrete," includes a permeable formwork and a temporary retaining wall. The permeable formwork is positioned around the large-volume concrete and is closely attached to its sidewalls. The temporary retaining wall is positioned around the permeable formwork and is spaced at a certain distance from it, forming a spatial structure. This spatial structure contains temperature-controlled intelligent circulating curing water, with the water level submerging the permeable formwork and the upper surface of the large-volume concrete, thus achieving full water coverage curing of the large-volume concrete. However, this method primarily protects the surface of the large-volume concrete and is not effective in controlling the internal temperature. Temperature variations can lead to cracks and fissures within the large-volume concrete. Summary of the Invention

[0004] This invention provides a precision temperature control curing system for large-volume concrete, which effectively reduces the influence of external and internal hydration heat on large-volume concrete, effectively controls the temperature difference between the inside and outside of large-volume concrete, thereby reducing the occurrence of cracks.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A precision temperature-controlled curing system for large-volume concrete includes multiple roller-type support groups installed at intervals along the length of a base, a bottom spraying mechanism installed between each roller-type support group and the base, multiple side-pushing mechanisms installed at both ends of the base at intervals along the length of the base, a large-volume concrete component mounted on the multiple roller-type support groups, multiple temperature sensing probes and multiple internal temperature control tubes pre-embedded in the large-volume concrete component, guide rails installed at both ends of the base in the width direction, each guide rail extending along the length of the base, and a traveling spraying mechanism assembled between two guide rails.

[0006] Furthermore, the roller support assembly includes multiple wheel units spaced apart along the width direction of the base. Each wheel unit includes a roller seat connected to the base via multiple support columns. Multiple support rollers are rotatably connected to the roller seat at intervals along the width direction of the base. Each support roller supports the lower end of the large-volume concrete component.

[0007] Furthermore, the bottom spraying mechanism includes a plurality of arc-shaped spraying elements spaced apart along the width direction of the base. Each arc-shaped spraying element is a plate-like structure and is arched upwards. A spraying cavity is formed inside the arc-shaped spraying element. The upper end of the arc-shaped spraying element is filled with first spraying holes communicating with the spraying cavity. A connecting pipe is connected to the lower end of the arc-shaped spraying element. The connecting pipe is connected to the water inlet branch pipe through a connecting channel in the base. The water inlet branch pipe is connected to the main water inlet pipe. A solenoid valve is installed on the water inlet branch pipe.

[0008] Furthermore, the side-pushing mechanism includes a transverse hydraulic cylinder mounted on the base, an adapter connected to the cylinder rod of the transverse hydraulic cylinder, and a jacking component mounted on the end of the adapter facing the large-volume concrete component.

[0009] Furthermore, an adapter sleeve is constructed on the adapter seat, and an adapter rod is constructed on the cylinder rod of the transverse hydraulic cylinder. The adapter rod is inserted into the adapter sleeve, and a connecting pin passes through the adapter sleeve and the adapter rod. A vertically extending strip hole is opened on the adapter seat, and one end of a transverse adjusting screw passes through the strip hole and is connected to the pusher. Two locking nuts are threaded onto the transverse adjusting screw, and the two locking nuts are respectively tightened at both ends of the adapter seat.

[0010] Furthermore, the traveling spray mechanism includes two arched rails spaced apart along the length of the guide rail. Each arch is spanned by the upper rail of the large-volume concrete component. A linear slide is installed at both ends of each arched rail, and each linear slide is mounted on a corresponding guide rail. A conforming traveling unit is mounted on each arched rail. Multiple spray hoses are spaced apart between the two conforming traveling units. The multiple spray hoses are spaced apart along the guide rail of the arched rail, and multiple second spray holes are opened at the end of each spray hose facing the large-volume concrete component.

[0011] Furthermore, the conformal traveling unit includes two active travel members spaced apart along the extension direction of the arched rail, and a plurality of passive travel members spaced apart between the two active travel members along the extension direction of the arched rail. Each passive travel member is mounted on the arched rail, and a transmission flexible shaft is rotatably connected to each active travel member and each passive travel member, and the transmission flexible shaft extends along the extension direction of the arched rail. Each spray hose is connected to the transmission flexible shaft, and a drive assembly for driving the transmission flexible shaft to rotate is installed on one of the active travel members.

[0012] Furthermore, the transmission flexible shaft includes multiple flexible shaft bodies spaced apart along the extension direction of the arched rail. Two adjacent flexible shaft bodies are connected by an elastic connecting assembly. Each flexible shaft body is connected to a corresponding spray hose, and the same end of the multiple spray hoses is connected to the main spray hose.

[0013] Furthermore, the elastic connection assembly includes a transfer tube rotatably mounted on the passive track component. The cross-section of the inner cavity of the transfer tube is a regular polygon. A sliding block with a regular polygonal cross-section is movably mounted inside the transfer tube. An movable rod with its end extending out of the transfer tube is connected to the sliding block. A connecting spring is installed inside the transfer tube. The connecting spring is connected to the transfer tube and the sliding block. The ends of the transfer tube and the movable rod that are far apart from each other are respectively connected to the corresponding flexible shaft bodies.

[0014] Furthermore, the internal temperature control tube includes a spiral heat exchange section arranged in a spiral shape within the large-volume concrete component. The axis of the spiral heat exchange section extends laterally along the base, and the medium outlet end of the spiral heat exchange section extends out of the large-volume concrete component from the axis of the spiral heat exchange section. The medium outlet end of the spiral heat exchange section and the medium inlet end of the spiral heat exchange section are located on the same side, and each of the temperature sensing probes is installed inside the corresponding spiral heat exchange section.

[0015] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, lie in the following: This invention pre-embeds multiple temperature sensing probes and multiple internal temperature control tubes within a large-volume concrete component, ensuring that the internal temperature control tubes and temperature sensing probes are evenly distributed within the component. Specifically, during the pouring of the large-volume concrete component, the internal temperature control tubes and temperature sensing probes are positioned at predetermined locations. After pouring, all internal temperature control tubes and temperature sensing probes are located within the large-volume concrete component. The internal temperature control tubes can be rigid metal pipes or flexible rubber hoses. When rigid metal pipes are used, they serve both as a conduit for the medium and as reinforcement for the large-volume concrete component, thereby increasing its strength. When using rubber hoses, to prevent deformation or localized sealing due to concrete pressure during pouring, a liquid medium is introduced into the hose. Once the hose is full, one end is sealed, and the pressure at the other end is stabilized to maintain the expected pressure. This prevents significant deformation during pouring. The pre-shaped large-volume concrete component is then transferred to a base, and a membrane, geotextile, or insulation blanket is placed over its outer surface. It is then supported by multiple roller-type support groups, followed by curing. Specifically, a bottom spray system sprays water onto the lower surface of the large-volume concrete component to adjust its temperature. The side-pushing mechanism is periodically controlled to move the component laterally along the base on the roller-type support groups, ensuring thorough cooling of the lower part of the component. Simultaneously, the traveling spray mechanism is controlled to reciprocate along the guide rail, spraying and cooling the large-volume concrete component circumferentially. This, combined with the spraying operation of the bottom spray mechanism, achieves comprehensive curing of the outer surface of the large-volume concrete component without any blind spots. Simultaneously, based on the temperature monitored by each temperature sensor, a liquid medium is introduced into the corresponding internal temperature control pipe, ensuring the internal temperature of the large-volume concrete component reaches a predetermined range. Therefore, this invention achieves comprehensive temperature control of the large-volume concrete component from both inside and out through the bottom spray mechanism, the traveling spray mechanism, and the internal temperature control pipe, preventing cracks and fissures caused by temperature differences. This invention can adjust the spray volume and the flow rate of the liquid medium through the internal temperature control pipe, as well as the temperature of the spray liquid and the liquid medium, according to different external temperature and humidity factors, ensuring that the internal and external temperatures of the large-volume concrete component remain within the predetermined range. In summary, this invention effectively reduces the impact of external and internal hydration heat on large-volume concrete components, effectively controls the temperature difference between the inside and outside of the large-volume concrete, and thus reduces the occurrence of cracks.

Detailed Implementation

[0019] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0020] This invention discloses a precision temperature control curing system for large-volume concrete, such as... Figure 1-17As shown, the system includes a base 100, a traveling spray mechanism 600, two guide rails 500, multiple roller support groups 200, and multiple side-push mechanisms 400. The multiple roller support groups 200 are spaced apart on the base 100 along its length. A bottom spray mechanism 300 is installed between each roller support group 200 and the base 100. The multiple side-push mechanisms 400 are divided into two groups, symmetrically installed at both ends of the base 100 in its width direction. Multiple side-push mechanisms 400 in each group are spaced apart along the length of the base 100. A large-volume concrete component 700 is mounted on the multiple roller support groups 200. Multiple temperature sensing probes and multiple internal temperature control tubes 800 are pre-embedded within the large-volume concrete component 700. The probe wire 900 of each temperature sensing probe extends out of the large-volume concrete component 700. The two guide rails 500 of the present invention are symmetrically installed at both ends of the base 100 in the width direction. Each guide rail 500 extends along the length direction of the base 100. The traveling spraying mechanism 600 is assembled between the two guide rails 500 and can spray the outer surface of the large-volume concrete component 700 except for the bottom surface. The working principle and advantages of this invention are as follows: This invention pre-embeds multiple temperature sensing probes and multiple internal temperature control tubes 800 within a large-volume concrete component 700, and ensures that the internal temperature control tubes 800 and temperature sensing probes are evenly arranged within the large-volume concrete component 700. That is, during the pouring of the large-volume concrete component 700, the internal temperature control tubes 800 and temperature sensing probes are placed at predetermined positions. After pouring is completed, the internal temperature control tubes 800 and temperature sensing probes are all within the large-volume concrete component 700. The internal temperature control tubes 800 can be rigid metal tubes or rubber hoses. When rigid metal tubes are used, they serve two purposes: firstly, to conduct the medium, and secondly, to reinforce the large-volume concrete component 700, thereby improving its strength. When using rubber hoses, to prevent deformation or localized sealing due to concrete pressure during pouring, a liquid medium is introduced into the hose. Once the hose is full, one end is sealed, and the pressure at the other end is stabilized to ensure the internal pressure remains within the expected range. This prevents significant deformation during pouring. The pre-shaped large-volume concrete component 700 is then transferred to the base 100, and a membrane, geotextile, or insulation blanket is placed over its outer surface. The component is then supported by multiple roller-type support assemblies 200, followed by curing.Specifically, the bottom spraying mechanism 300 is controlled to spray water onto the lower surface of the large-volume concrete component 700, thereby adjusting the temperature of the lower part of the large-volume concrete component 700. Simultaneously, the side-pushing mechanism 400 is periodically controlled to move, causing the large-volume concrete component 700 to reciprocate laterally along the base 100 on multiple roller support groups 200, ensuring thorough cooling of the lower part of the large-volume concrete component 700. Simultaneously, the traveling spraying mechanism 600 is controlled to reciprocate along the guide rail 500, spraying water along the circumference of the large-volume concrete component 700 to cool it. This, combined with the spraying operation of the bottom spraying mechanism 300, achieves thorough curing of the outer surface of the large-volume concrete component 700. At the same time, based on the temperature monitored by each temperature sensor, a liquid medium is introduced into the corresponding internal temperature control pipe 800, ensuring that the internal temperature of the large-volume concrete component 700 reaches a predetermined range. Therefore, this invention achieves comprehensive temperature control of the large-volume concrete component 700, both inside and out, through the bottom spraying mechanism 300, the traveling spraying mechanism 600, and the internal temperature control pipe 800, thus preventing cracks and fissures caused by temperature differences. This invention can adjust the spraying volume and the flow rate of the liquid medium through the internal temperature control pipe 800, as well as the temperature of the spraying liquid and the liquid medium, according to different external temperature and humidity factors, ensuring that the internal and external temperatures of the large-volume concrete component 700 remain within a predetermined range. In summary, this invention effectively reduces the impact of external and internal hydration heat on the large-volume concrete component 700, effectively controls the temperature difference between the inside and outside of the large-volume concrete, and thus reduces the occurrence of cracks.

[0021] As a preferred embodiment of the present invention, such as Figure 3-5As shown, the roller support assembly 200 includes multiple wheel units, which are spaced apart along the width direction of the base 100. Each wheel unit includes a roller seat 202, multiple support columns 201, and multiple support rollers 203. The support columns 201 connect the roller seat 202 to the base 100, and the roller seat 202 is located above the base 100. The multiple support rollers 203 are rotatably connected to the roller seat 202 at intervals along the width direction of the base 100, and each support roller 203 is supported at the lower end of the large-volume concrete component 700. In this embodiment, the support rollers 203 support the large-volume concrete component 700. When the bottom spraying mechanism 300 controls the temperature of the bottom surface of the large-volume concrete component 700, the support rollers 203 partially shield the lower end of the large-volume concrete component 700. At this time, it is necessary to control the side-pushing mechanism 400 to drive the large-volume concrete component 700 to move a certain distance along the width direction of the base 100, so as to expose the shielded part and carry out effective temperature control. Due to the setting of the roller support group 200, the movement of the large-volume concrete component 700 on the base 100 is smoother, reducing friction and thus avoiding damage to the large-volume concrete component 700. Moreover, during the curing process of the large-volume concrete component 700, the side-pushing mechanism 400 also plays a role in limiting the movement of the large-volume concrete component 700.

[0022] As a preferred embodiment of the present invention, such as Figure 3-5As shown, the bottom spraying mechanism 300 includes multiple arc-shaped spraying elements 301, which are spaced apart along the width direction of the base 100. Each arc-shaped spraying element 301 has a plate-like structure and is arched upwards. A spraying cavity is formed inside the arc-shaped spraying element 301, and first spraying holes are distributed at the upper end of the arc-shaped spraying element 301, with each first spraying hole connected to the spraying cavity. In this embodiment, a connecting pipe 302 is connected to the lower end of each arc-shaped spraying element 301. A connecting channel is opened in the base 100 at a location corresponding to each bottom spraying mechanism 300. Each connecting channel is connected to a water inlet branch pipe 303, and each water inlet branch pipe 303 is connected to a main water inlet pipe 305. A solenoid valve 304 is installed on each water inlet branch pipe 303, and each connecting pipe 302 is connected to a corresponding connecting channel. The working principle and advantages of this embodiment are as follows: Pressurized water is introduced into the main inlet pipe 305. Then, based on the area at the bottom of the large-volume concrete component 700 where temperature control is required, the corresponding solenoid valve 304 is opened. The pressurized water enters the corresponding connecting channel through the corresponding inlet branch pipe 303, and then enters each spray chamber through multiple connecting pipes 302 connected to the connecting channel. Finally, it is atomized and sprayed out from the upper end of the arc-shaped spray element 301, thereby achieving the purpose of temperature control for the corresponding area at the bottom of the large-volume concrete component 700. Because the arc-shaped spray element 301 adopts an arc-shaped design, the atomized spray water is sprayed in a fan shape towards the bottom of the large-volume concrete component 700, increasing the spray area and improving the temperature control effect.

[0023] As a preferred embodiment of the present invention, such as Figure 3 , 6As shown in Figure 7, the side-pushing mechanism 400 includes an adapter 401, a transverse hydraulic cylinder 403, and a pushing member 408. One end of the cylinder body of the transverse hydraulic cylinder 403 is mounted on the base 100, and the transverse hydraulic cylinder 403 extends outward along the width direction of the base 100. The adapter 401 is connected to the cylinder rod of the transverse hydraulic cylinder 403, and the pushing member 408 is mounted on the end of the adapter 401 facing the large-volume concrete component 700. Thus, when it is necessary to drive the large-volume concrete component 700 to change position on the base 100, the transverse hydraulic cylinder 403 is controlled to move, causing it to drive the pushing member 408 via the adapter 401 to push the large-volume concrete component 700 along the width direction of the base 100, so that the covered parts of the large-volume concrete component 700 are exposed, allowing the bottom spraying mechanism 300 to perform temperature control operations on it. In this embodiment, to avoid the side-pushing mechanism 400 obstructing the large-volume concrete component 700, thus preventing the traveling spraying mechanism 600 from fully controlling the external surface temperature of the large-volume concrete component 700, and to avoid interfering with the transfer of the large-volume concrete component 700 (to the roller support group 200 or by the roller support group 200), the following measures are taken: an adapter sleeve 405 is constructed on the adapter seat 401, and an adapter rod 404 is coaxially constructed on the cylinder rod of the transverse hydraulic cylinder 403. The adapter rod 404 is inserted into the adapter sleeve 405, and a connecting pin 406 is used to pass through the adapter sleeve 405 and the adapter rod 404 to restrict the position of the adapter sleeve 405 and the adapter rod 404. In this position, the adapter seat 401 is in a vertical state, and the pusher 408 is located at the lower part of the side facing the large-volume concrete component 700. When the large-volume concrete component 700 is not being driven, the connecting pin 406 is removed, and the adapter 401 is rotated, causing the upper end of the adapter 401 to drive the pusher 408 to rotate downwards along the axis of the adapter rod 404 until it avoids the atomizing spray area of ​​the traveling spray mechanism 600. In this embodiment, the pushing position of the pusher 408 on the large-volume concrete component 700 can be adjusted. Specifically, a strip hole 402 is provided on the adapter 401, which extends vertically. One end of a transverse adjusting screw 407 is passed through the strip hole 402 and connected to the pusher 408. Two locking nuts 409 are threaded onto the transverse adjusting screw 407, and these two locking nuts 409 are respectively tightened at both ends of the adapter 401. The transverse adjusting screw 407 extends along the width direction of the base 100. In this embodiment, by adjusting the vertical position of the horizontal adjusting screw 407 at the strip hole 402, the vertical position of the jacking component 408 is adjusted, thereby achieving the purpose of jacking the large-volume concrete component 700 at different positions.In this embodiment, the distance between the lateral adjusting screw 407 and the large-volume concrete component 700 can be adjusted according to the different widths of the large-volume concrete component 700, thereby adjusting the distance between the jacking component 408 and the corresponding side of the large-volume concrete component 700, so that under the drive of the lateral hydraulic cylinder 403, the jacking component 408 can perform jacking operations on large-volume concrete components 700 of different widths.

[0024] As a preferred embodiment of the present invention, such as Figure 8-13 As shown, the traveling sprinkler mechanism 600 includes two arched rails 601, two conformal traveling units, and multiple sprinkler hoses 603. The two arched rails 601 are spaced apart along the length of the guide rail 500. Each arch is spanned by the upper rail of the large-volume concrete component 700. Linear slides 608 are installed at both ends of each arched rail 601, and each linear slide 608 is mounted on a corresponding guide rail 500 and can travel along the guide direction of the guide rail 500. In this embodiment, the two conformal traveling units are installed one-to-one on the two arched rails 601. The multiple sprinkler hoses 603 are spaced apart between the two conformal traveling units, and these sprinkler hoses 603 are spaced apart along the guide direction of the arched rails 601. Multiple second spray holes are opened at the end of each sprinkler hose 603 facing the large-volume concrete component 700. This embodiment controls the synchronous and unidirectional movement of four linear slides 608, causing two arched rails 601 to move along guide rails 500. This enables multiple spray hoses 603 to perform atomization and spraying operations on the large-volume concrete component 700, guided by the guide rails 500. This embodiment also controls the synchronous and unidirectional movement of two conformal traveling units, causing them to drive all the spray hoses 603 to move along the arched rails 601, thereby achieving circumferential surface temperature control of the large-volume concrete component 700.

[0025] As a preferred embodiment of the present invention, such as Figure 9-13As shown, the conformal traveling unit includes a drive shaft 602, two active travel members 604, and multiple passive travel members 606. The two active travel members 604 are spaced apart along the extension direction of the arched rail 601. The multiple passive travel members 606 are positioned between the two active travel members 604 and are also spaced apart along the extension direction of the arched rail 601. Each active travel member 604 and each passive travel member 606 is mounted on the arched rail 601. In this embodiment, the drive shaft 602 is rotatably connected to each active travel member 604 and each passive travel member 606, and extends along the extension direction of the arched rail 601. Each spray hose 603 is connected to the drive shaft 602. A drive assembly 605 is mounted on one of the active travel members 604, and this drive assembly 605 drives the drive shaft 602 to rotate. In this embodiment, by controlling all active track components 604 to move synchronously and in the same direction along the arched rail 601, the two following travel units drive all the spray hoses 603 to move along the arched rail 601. These spray hoses 603 atomize pressurized water and spray it onto the outer surface of the large-volume concrete component 700. When it is necessary to adjust the spray range of the spray hoses 603, the linear motors on the two arched rails 601 are controlled to move asynchronously, reducing the distance between the two arched rails 601. Then, the drive assembly 605 is controlled to rotate, causing one of the transmission flexible shafts 602 to rotate. This winds the ends of all the spray hoses 603 onto the transmission flexible shaft 602, reducing the length of the spray hoses 603 and ensuring that the portion of the spray hose 603 located between the two following travel units remains taut, thus ensuring that the atomization spraying operation is not affected. The active track component 604 in this embodiment includes a first base 6041 and a first power motor 6042. The first power motor 6042 is mounted on the first base 6041. A transmission gear 6043 is coaxially mounted on the output shaft of the first power motor 6042. The transmission gear 6043 meshes with a transmission rack on the arched rail 601. The transmission gear 6043 extends along the guide of the arched rail 601 to both ends of the arched rail 601. Two first transmission wheels 6044 are rotatably connected to both sides of the first base 6041. Each first transmission wheel 6044 is rolled along the lateral edge of the arched rail 601, thereby achieving the purpose of mounting the first base 6041 on the arched rail 601. In this embodiment, by controlling the operation of the first power motor 6042, the first base 6041 moves along the arched rail 601 under the transmission of the transmission gear 6043 and the transmission rack.The drive assembly 605 in this embodiment includes a second power motor 6051, which is mounted on a first base 6041. A drive wheel 6052 is coaxially mounted on the output shaft of the second power motor 6051, and a driven wheel 6053 is coaxially mounted on one end of a transmission flexible shaft 602. The drive wheel 6052 and the driven wheel 6053 are connected by a transmission belt 6054. When both the drive wheel 6052 and the driven wheel 6053 are sprockets, they are connected by a transmission chain. A first connecting arm 6055 is mounted on the first base 6041, and a first connecting sleeve 6056 is constructed on the first connecting arm 6055. The portion of the transmission flexible shaft 602 near the driven wheel 6053 is rotatably mounted within the first connecting sleeve 6056. In this embodiment, the second power motor 6051 is controlled to rotate the transmission flexible shaft 602 via belt drive or sprocket drive. This causes the transmission flexible shaft 602 to wind or unwind the end of the passive guide member 606 of the spray hose 603, thereby changing the effective spraying length of the spray hose 603. The passive guide member 606 in this embodiment includes a second base 6061. Two second transmission wheels 6062 are rotatably mounted on both sides of the second base 6061, i.e., two second transmission wheels 6062 are respectively provided on both sides of the arched rail 601. Each second transmission wheel 6062 is rolled along the lateral edge of the arched rail 601, thus enabling the second base 6061 to be mounted on the arched rail 601. A second connecting arm 6063 is constructed on the second base 6061, and a second connecting sleeve 6064 is constructed on the second connecting arm 6063. The transmission flexible shaft 602 passes through the second connecting sleeve 6064 and is drively connected to the second connecting sleeve 6064. When the active track member 604 moves along the guide direction of the arched rail 601, it drives each passive track member 606 to move along the guide direction of the arched rail 601 through the transmission flexible shaft 602. Moreover, since the transmission flexible shaft 602 is connected by multiple passive track members 606 at the nodes, the transmission flexible shaft 602 bends and deforms with the shape of the arched rail 601 during the movement along the arched rail 601. During this process, it does not affect the drive assembly 605 from driving the transmission flexible shaft 602 to rotate.

[0026] As a preferred embodiment of the present invention, such as Figure 14-16As shown, the drive flexible shaft 602 includes multiple flexible shaft bodies 6021, which are spaced apart along the extension direction of the arched rail 601. Adjacent flexible shaft bodies 6021 are connected by an elastic connecting assembly. Each flexible shaft body 6021 is connected to a corresponding spray hose 603, and the same end of the multiple spray hoses 603 is connected to a main spray hose 607. Pressurized water is supplied to each spray hose 603 through the main spray hose 607 and then atomized and sprayed onto the outer surface of the large-volume concrete component 700 from each spray hose 603. The elastic connection assembly of this embodiment includes a connecting pipe 6022, a sliding block 6026, a movable rod 6025, a connecting spring 6027, and a connecting cover 6024. The connecting pipe 6022 is rotatably mounted on the passive track member 606. The cross-section of the inner cavity 6023 of the connecting pipe 6022 is a regular polygon. The sliding block 6026 is slidably assembled inside the connecting pipe 6022. The cross-section of the sliding block 6026 is a regular polygon. One end of the connecting pipe 6022 is in a closed state, and the other end of the connecting pipe 6022 is detachably connected to the connecting cover 6024. One end of the movable rod 6025 is fixedly connected to the sliding block 6026, and the other end of the movable rod 6025 moves through the connecting cover 6024 and extends out of the connecting pipe 6022. A connecting spring 6027 is installed inside the adapter tube 6022. The connecting spring 6027 is connected to the adapter tube 6022 and the sliding block 6026. The ends of the adapter tube 6022 and the movable rod 6025 that are far apart from each other are respectively connected to the corresponding flexible shaft bodies 6021. In this embodiment, the length of the transmission flexible shaft 602 can be adjusted, that is, the movement of two active track members 604 on the same conformal traveling unit can be controlled, and the two generate a certain tension difference on the flexible shaft body 6021, thereby causing the transmission flexible shaft 602 to be elastically stretched. That is, all elastic connecting components are elastically stretched synchronously, so that the distance between adjacent flexible shaft bodies 6021 is adjusted. When equilibrium is reached, the distance between adjacent spray hoses 603 is adjusted, thereby adjusting the area of ​​the atomized spray of the traveling spray mechanism 600.

[0027] As a preferred embodiment of the present invention, such as Figure 17As shown, the internal temperature control tube 800 includes a spiral heat exchange section 801, which is spirally arranged inside the large-volume concrete component 700. The axis of the spiral heat exchange section 801 extends laterally (in the width direction) along the base 100, and the medium outlet end 803 of the spiral heat exchange section 801 extends out of the large-volume concrete component 700 from the axis of the spiral heat exchange section 801. The medium outlet end 803 and the medium inlet end 802 of the spiral heat exchange section 801 are located on the same side and extend out of the large-volume concrete component 700. Each temperature sensing probe is installed inside the corresponding spiral heat exchange section 801. In this embodiment, the use of the spiral heat exchange section 801 increases its contact area with the interior of the large-volume concrete component 700 and the continuity of its contact with the large-volume concrete component 700. When the temperature sensing probe detects a temperature change, the liquid medium efficiently controls the temperature of the large-volume concrete component 700 (heat exchange, removing a large amount of heat). Furthermore, after the large-volume concrete component 700 has been cured, concrete is injected into the internal temperature control pipe 800, so that the inner and outer parts of the internal temperature control pipe 800 are bonded to the large-volume concrete component 700. This prevents the large-volume concrete component 700 from being subjected to external forces that compress the hollow internal temperature control pipe 800 during long-term use, thus avoiding internal stress and causing deformation or cracks inside the large-volume concrete component 700.
