[0002] The plateau climate is quite special, with large temperature differences and low air humidity. In this environment, concrete is prone to shrinkage and cracking when solidifying. 0# blocks have the disadvantages of large size and long curing time. For 0# blocks in plateau areas, the temperature is lower than that in plains and the temperature difference between day and night is large, so it is inconvenient for staff to inspect and maintain them.

[0003] The 0# blocks located in the plateau area do not necessarily need physical cooling methods, so spraying maintenance is only required when the temperature difference of the concrete is greater than 20 degrees. The existing concrete pouring method is to pour from bottom to top, and the volume poured at one time cannot be too large, otherwise there will be a risk of cracking.

[0013] A method for maintaining a concrete hydration heat temperature control structure, comprising the following steps: S1: The staff first fixes the first steel cage at the designated position, and then fixes several groups of second steel cages and several groups of third steel cages to the first steel cage, and then uses the formwork to surround the first steel cage, several groups of second steel cages and several groups of third steel cages, and then wraps a layer of polypropylene film around the outside of the fixed column and installs it inside the first steel cage, several groups of second steel cages and several groups of third steel cages, and then the staff pours concrete into the formwork.

[0014] S2: When the concrete frame is initially solidified, the staff will pull out the fixed columns and remove the formwork. Then, they will place several groups of temperature sensors on the surface of the concrete frame and at the center of the through hole. When the temperature difference between the inside and outside of the concrete frame reaches 20 degrees, the staff will spray water on the surface of the concrete frame and inject water into the polypropylene film to cool down and maintain the concrete frame. When the temperature difference drops to an appropriate level, the staff will stop and repeat this process until the concrete frame is completely solidified.

[0015] S3: Then several groups of temperature sensors are removed, and then four groups of fourth steel cages are fixed at designated positions, and then four groups of main heat dissipation racks are installed at designated positions, and then several groups of first connecting plates are installed, and the two sides of the first connecting plates are respectively connected to the main heat dissipation racks. At the same time, one end of the first connecting plate is moved between the two groups of fifth steel cages, and then the second connecting plate is fixed to the two groups of main heat dissipation racks.

[0016] S4: The staff installs the main formwork at the designated location, and then pours concrete into the main formwork. After the concrete is initially solidified, the staff places several groups of temperature sensors on the concrete surface and at the connection between the second connecting plate and the main heat sink, and opens holes on the top and bottom second connecting plates. When the temperature difference between the inside and outside of the concrete reaches 20 degrees, the staff sprays water on the concrete surface and injects water into the second connecting plate to cool the concrete and prevent it from cracking. When the temperature difference drops to a suitable temperature, the staff stops, and repeats this process until the concrete is completely solidified.

[0017] S5: The staff takes out the second connecting plate, and finally injects concrete into the main heat sink and the first connecting plate, so that the main formwork is completely filled with concrete, completing the pouring of the 0# block.

[0018] The working principle and beneficial effects of this solution are: When pouring 0# block, workers only need two pouring times to complete the pouring of the main body of 0# block, which can improve the efficiency of concrete block pouring. Moreover, during the two pourings of concrete, the contact area is larger, which can ensure that the two groups of concrete can form a whole and ensure that the strength of the concrete meets the standard.

[0019] When pouring in sections, the concrete blocks have a unique shape and a large surface area, which can facilitate faster heat dissipation of the concrete blocks, thereby reducing the impact of hydration heat and reducing the temperature difference inside and outside the concrete blocks. At the same time, the staff can monitor the temperature difference in real time. When the external temperature difference reaches 20 degrees, the staff can perform physical cooling in time to prevent the concrete from cracking. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] A method for maintaining a concrete hydration heat temperature control structure, comprising the following steps: S1: The staff first fixes the first steel cage 201 at the designated position, and then fixes several groups of second steel cages 202 and several groups of third steel cages 203 to the first steel cage 201, and then uses a template to surround the first steel cage 201, and then wraps a layer of polypropylene film around the outside of the fixing column 204, and then respectively installs several groups of fixing columns 204 in the first steel cage 201, several groups of second steel cages 202 and several groups of third steel cages 203, and then the staff pours concrete into the template.

[0030] S2: After the concrete frame 301 is initially solidified, the staff will pull out the fixed column 204, and the polypropylene film will remain in place. Then the staff will remove the template and place several groups of temperature sensors on the surface of the concrete frame 301 and at the center of the through hole 305. At the same time, waterproof measures need to be taken for the temperature sensor placed in the center of the through hole 305. When the temperature difference between the inside and outside of the concrete frame 301 reaches 20 degrees, the staff will spray water on the surface of the concrete frame 301 and inject water into the polypropylene film to cool down and maintain the concrete frame 301 to prevent the concrete frame 301 from cracking. When the temperature difference drops to a suitable temperature, stop, and repeat this process until the concrete frame 301 is completely solidified.

[0031] S3: Then, several groups of temperature sensors are removed, and four groups of fourth steel cages 401 are fixed at designated positions, so that the fifth steel cage 402 is located between two adjacent groups of second concrete blocks 303, and the third concrete block 304 is located between two adjacent groups of sixth steel cages 403. Then, four groups of main heat sinks 501 are installed at designated positions, and the second clamping blocks 506 are clamped on another group of corresponding main heat sinks 501, so that the corresponding two groups of main heat sinks 501 are initially fixed, and the two groups of main heat sinks 501 are internally connected. Then, the staff installs several groups of first connecting plates 502, and clamps the first connecting plates 502 on the two groups of the first connecting plates 502. The two concrete blocks 303 are used to connect the two groups of main heat sinks 501 that are located on the same side and are not in contact. The first clamping block 503 is clamped in the corresponding first clamping slot 504. The two sides of the first connecting plate 502 are respectively connected to the main heat sink 501. At the same time, one end of the first connecting plate 502 is moved between the two groups of fifth steel cages 402. Then the staff moves the second connecting plate 505 between the two groups of sixth steel cages 403. The staff controls the fixing assembly through the control element to fix the second connecting plate 505 to the two groups of main heat sinks 501. At this time, the two groups of matching columns 608 are fixed by the fastening elements at the same time.

[0032] S4: The staff installs the main formwork 1 at the designated position. At this time, several groups of second connecting plates 505 of the main formwork 1 are all clamped on the main formwork 1, and one end of the second connecting plate 505 is located outside the main formwork 1. Then the staff pours concrete into the main formwork 1. After the concrete is initially solidified, the staff places several groups of temperature sensors on the concrete surface and at the connection between the second connecting plate 505 and the main heat dissipation frame 501, and at the same time, holes are opened on the top and bottom second connecting plates 505. When the temperature difference between the inside and outside of the concrete reaches 20 degrees, the staff sprays water on the concrete surface and injects water into the top second connecting plate 505. Then the water flows in the main heat dissipation frame 501, the first connecting plate 502 and the second connecting plate 505, and then flows out from the bottom second connecting plate 505 to cool down and maintain the concrete to prevent the concrete from cracking. When the temperature difference drops to a suitable temperature, it stops, and this process is repeated until the concrete is completely solidified.

[0033] S5: The staff releases the fixation of the fixing assembly, and then pulls the matching column 608 to break the elastic block 609 and the conical block 610, so that the conical block 610 remains on the conical groove 611. At this time, the fixation between the second connecting plate 505 and the main heat dissipation frame 501 is released, and then the staff takes out the second connecting plate 505, and then cleans out the conical block 610 remaining in the conical groove 611 to prevent the residual material of the conical block 610 from damaging the structural strength of the concrete frame 301. Finally, concrete is injected into the main heat dissipation frame 501 and the first connecting plate 502 to completely fill the main template 1 with concrete, completing the pouring of the 0# block.

[0034] When implementing: When the staff uses the fixing element to fix the second connecting plate 505, they first make the second connecting plate 505 contact with the connection between the two groups of main heat dissipation frames 501. At this time, the second connecting plate 505 is connected with the two groups of main heat dissipation frames 501. Then the staff controls the matching column 608 to pass the two groups of tapered blocks 610 through the tapered groove 611 in turn, and then pulls the matching column 608 to make the two groups of tapered blocks 610 contact. At this time, the two groups of matching columns 608 are not in contact. At the same time, it is ensured that the two groups of matching columns 608 are distributed up and down, and the angle between the two groups of matching columns 608 is an acute angle. Then the staff moves one group of connecting rods 603 to make the other group of connecting rods 603 clamped in the connecting block 604, and then clamps the two groups of matching columns 608 respectively on the two The two sets of movable blocks 602 are moved in the UU-shaped block 607, and then the connecting rod 603 is moved horizontally. The connecting rod 603 drives the two sets of movable blocks 602 to move. When the connecting block 604 is closer to the matching block 601 close to the conical block 610, the resistance to movement is greater due to the elastic block 609. At the same time, the two sets of conical blocks 610 are in closer contact, and the distance between the two sets of matching columns 608 is closer, until the movable block 602 is aligned with the matching block 601. At this time, the first limit block 605 is clamped in the corresponding matching block 601. At the same time, the two sets of matching columns 608 are in contact with each other, and the two sets of threaded columns 612 form a complete thread. Then the staff twists the fixed sleeve 613 on the two sets of threaded columns 612, and the fixed sleeve 613 is connected to the two sets of threaded columns 612 through threads.

[0035] The staff continues to rotate the fixing sleeve 613, and the fixing sleeve 613 first moves toward the direction close to the second connecting plate 505 until the second connecting plate 505 contacts the ball 622. Then the staff continues to rotate the fixing sleeve 613, and the fixing sleeve 613 rotates on the ball 622, and the ball 622 rolls in the fixing seat 621. At this time, the fixing sleeve 613 rotates to drive the threaded column 612 to move toward the direction of the second connecting plate 505, and the threaded column 612 drives the matching column 608, the elastic block 609 and the tapered block 610 to move until the tapered block 610 is stuck in the tapered groove 611. At this time, the fixing sleeve 613 is stopped from rotating, and then the staff first The stopper 618 is taken out from the fixing frame 617, and the second limit block 620 is moved upward. The second limit block 620 drives the movable rod 619 to slide in the second fixing groove 616 until the second limit block 620 moves between the second connecting plate 505 and the fixing sleeve 613. At this time, the movable rod 619 is separated from the second fixing groove 616. Then the staff inserts the stopper 618 into the two sets of fixing frames 617, and then releases the second limit block 620. The second limit block 620 drives the movable rod 619 to move downward by gravity until the movable rod 619 contacts the stopper 618. At this time, the fixation between the second connecting plate 505 and the main heat dissipation frame 501 is completed.

[0036] When it is necessary to release the fixation between the second connecting plate 505 and the main cooling rack 501, the staff continues to rotate the fixing sleeve 613. At this time, the force required for the rotation of the fixing sleeve 613 is greater. The force during the rotation of the fixing sleeve 613 is converted into a pulling force between the conical block 610 and the elastic block 609 through the thread, until the pulling force exceeds the threshold that the connection between the elastic block 609 and the conical block 610 can withstand. At this time, the elastic block 609 is separated from the conical block 610, and then the staff can remove the second connecting plate 505 from the concrete.

[0037] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the present invention.
