Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing equipment, in particular to concrete curing equipment in severe cold areas. Background Art

[0002] At present, the mainstream traditional curing methods for round pier concrete of bridges include: first, when the environment is at a positive temperature, after the formwork is removed, the entire surface of the pier is wrapped with plastic cloth, and then a rope is used to wrap and tie several circles around the outer circumference of the pier. The principle of this curing method is to isolate the pier from the air and use the hydration of concrete mixing water to generate strength; second, when the ambient temperature is negative, after the formwork is removed, the entire surface of the pier is wrapped with cotton felt cloth, and then a heating device such as a hot air gun is used to increase the surface temperature of the pier, artificially creating a positive temperature environment, so that the strength of the round pier concrete increases in the positive temperature environment.

[0003] However, the defects of the first curing method include: 1. In order to prevent temperature leakage, the plastic sheet needs to be placed close to the surface of the round pier concrete. However, no matter how carefully the operator operates and how dense the rope winding density is, the winding and binding of the plastic sheet cannot ensure that there are no gaps at the joints of the plastic sheet; if the worker's operation is arbitrary, it is even more impossible to ensure that there are no gaps at the joints of the plastic sheet, which can easily cause the evaporation and loss of mixing water in the pier concrete. 2. The insulation material is close to the surface of the round pier concrete, which will cause the mixing water volatilized in the pier to be absorbed by the insulation material, resulting in a lack of humidity in the concrete during the strength growth process, which will lead to poor curing and insulation effects, slow concrete strength growth, and affect the construction of the next process. The effect is low. 3. After the mixing water in the concrete evaporates and loses, the cement hydration in the concrete cannot be fully carried out, so the activity of the cement cannot be fully exerted, which wastes cement resources. In order to achieve the design strength of pier concrete, increasing the unit cement consumption is one of the main ways, which runs counter to the current concepts of "green energy conservation and environmental protection, sustainable development, carbon peak, and carbon neutrality". 4. The plastic sheeting wrapped around the pier is easily damaged by strong winds, and the chance of secondary use is very small, which increases the cost of maintenance.

[0004] The defects of the second curing method include: 2. Highway bridge construction is almost always done in the field, and the power supply cannot be fully guaranteed. 2. The heat source provided by the hot air cannon has extremely uneven temperatures at different heights and different parts of the entire pier, affecting the appearance and overall quality of the concrete. 3. The heat source provided by the hot air cannon is particularly dry and highly hygroscopic, which has a negative impact on the humidity required for the growth of concrete strength and is not conducive to the growth of concrete strength. 4. This curing method is prone to shrinkage cracks in concrete. Utility Model Content

[0005] The utility model solves the problem that the existing curing method for the concrete of the bridge round pier column uses a heating device to increase the surface temperature of the pier column, but there are problems such as power supply timeliness, uneven temperature maintenance, and excessive drying causing shrinkage cracks in the concrete. At the same time, the utility model also solves the problem that the existing curing method for the concrete of the bridge round pier column makes the insulation material close to the surface of the round pier column concrete, resulting in a lack of humidity in the concrete during the strength growth process, resulting in poor curing and insulation effects and slow concrete strength growth.

[0006] To achieve the above purpose, the utility model provides the following solutions:

[0007] The utility model provides an energy-saving and environmentally friendly integrated curing device for round bridge pier concrete, the device comprising a plurality of standard segments, a plurality of connecting flanges and a top cover plate;

[0015] Furthermore, in a preferred embodiment, the above-mentioned standard segment further includes a segment cover;

[0016] The segment cover is provided with a groove, which is used to allow the end plate of the partition of the five-layer hollow chamber to be inserted into the groove of the segment cover to form the five-layer hollow chamber.

[0017] Furthermore, in another preferred embodiment, the thickness of the first chamber, the second chamber and the fifth chamber are all 20 mm;

[0018] The thickness of the third chamber and the fourth chamber is 50 mm.

[0019] Furthermore, in a preferred embodiment, the thermal conductivity of the third chamber and the fourth chamber are both smaller than that of the first chamber, the second chamber and the fifth chamber.

[0024] Furthermore, in a preferred embodiment, the organic thermal insulation material is black polystyrene particles; and the inorganic thermal insulation material is black glass wool particles.

[0025] Furthermore, in a preferred embodiment, the materials of the connecting flange and the top cover plate are both organic composite light-transmitting plates.

[0026] Furthermore, in a preferred embodiment, the top cover plate is a hollow cylindrical structure, and the internal structure of the hollow cylinder is the same as the internal structure of the standard segment.

[0027] Furthermore, in a preferred embodiment, the height of the above-mentioned standard segment is 2m.

[0028] The beneficial effects of the utility model are:

[0029] 1. The utility model provides an energy-saving and environmentally friendly integrated curing device for round bridge pier concrete, which is formed into a hollow cylinder by a plurality of standard segments. A top cover plate is fixed on the hollow cylinder to form a sealed hollow cylinder, so that the curing device can completely wrap the round bridge pier. Furthermore, the standard segment is a hollow semi-cylindrical structure with five layers of hollow chambers, and the first, second and fifth chambers of the five layers of hollow chambers are all vacuum insulation layers, and the third and fourth chambers are filled with a mixture of insulation materials, so that an insulating, heat-insulating and moisture-retaining cavity is formed between the concrete pier and the concrete curing device, thereby realizing the curing of the concrete pier.

[0030] Furthermore, compared with the prior art, the utility model does not require the aid of an external heating device, but can achieve the curing of the bridge round pier concrete by using the solar radiation heat energy and the heat energy generated by the cement hydration in the concrete. At the same time, the temperature generated is uniform, saving energy waste.

[0031] Furthermore, compared with the prior art, the utility model achieves moisture retention of the round pier column concrete through the fifth chamber, thereby ensuring that the mixing water inside the concrete is not lost, solving the problem that the existing use of hot air guns and other heating devices to heat the round pier column concrete of bridges is not conducive to the increase of concrete strength and causes shrinkage cracks.

[0032] Furthermore, compared with the prior art, the utility model does not need to place the thermal insulation material close to the surface of the round pier column concrete, but forms a 20mm thick vacuum buffer layer between the thermal insulation layer and the concrete pier column, so that the mixing water volatilized from the pier column will not be absorbed by the thermal insulation material, so as to ensure that the surface of the pier column is always in a moist state, thus ensuring the continuous supply of hydration water required for the concrete during the strength growth process. That is, the 20mm thick space is used to achieve both thermal insulation and moisture retention, so that the thermal insulation efficiency is increased by 20 times compared with placing the thermal insulation material close to the surface of the round pier column concrete.

[0033] Furthermore, during the period of high ambient temperature in summer, the energy-saving and environmentally friendly integrated health-care device described in the utility model will form a greenhouse effect inside the integrated health-care device, resulting in high internal temperature and humidity. In this season, when the highest air temperature during the day is 25±5°C, the surface temperature of the pier column concrete can be between 40 and 60°C, and the humidity is greater than 90%RH; when the lowest air temperature at night is 15±5°C, the surface temperature of the pier column concrete can still be maintained at around 20 to 30°C, and the humidity is greater than 90%RH. The strength of concrete grows rapidly in this season, which can greatly shorten the curing time of concrete. The strength of the pier column concrete can reach the design strength in about 3 days, greatly improving the curing efficiency of the pier column concrete. At the turn of spring and summer, late autumn and early winter, when the lowest air temperature is between -8 and 10°C, and the daily average temperature is between 5 and 15°C, the integrated health-care device can be used to cure the pier column, so that the pier column concrete can be cured without any form of heating, and the compressive strength can reach the design strength in 5d to 10d. In this season, when the highest air temperature during the day is 10±5℃, the surface temperature of the pier column concrete can reach about 20-30℃, and the humidity is greater than 90%RH; when the lowest air temperature at night is between -8±5℃, the surface temperature of the pier column concrete can still be maintained at about 10-20℃, and the humidity is greater than 90%RH. The temperature and humidity conditions required for concrete hydration can be fully met, and the strength can be guaranteed.

[0034] Furthermore, the energy-saving and environmentally friendly integrated curing device described in the utility model extends the concrete cycle of bridges in cold regions. In the past, when the daily average temperature was less than or equal to 5°C, winter construction measures had to be taken to heat the concrete before construction could be carried out. After adopting the integrated concrete curing device described in the utility model, even if the lowest ambient temperature is lower than -10°C and the daily average temperature is between 1°C and 5°C, concrete construction can still be carried out without taking any heating measures. The utility model expands the temperature adaptability range of concrete construction, greatly reduces construction costs, and improves construction efficiency.

[0035] Furthermore, the energy-saving and environment-friendly integrated health-preserving device described in the utility model can be recycled many times, and the comprehensive cost is much lower than that of traditional health-preserving methods.

[0036] The utility model is suitable for arid and semi-arid climate zones, and is particularly suitable for curing concrete of circular piers of bridges which have large temperature differences between day and night and need to be constructed under negative temperature conditions.

[0042] The specific implementation methods of the utility model are further described in detail below in conjunction with the accompanying drawings and examples. The following examples will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.

[0043] Implementation method 1, see Figures 1 to 3This embodiment is described. This embodiment provides an energy-saving and environmentally friendly integrated curing device for round pier concrete of a bridge. The device includes a plurality of standard segments 1, a plurality of connecting flanges and a top cover plate 2;

[0044] The plurality of standard segments 1 are surrounded by a plurality of connecting flanges to form a hollow cylinder, and the top cover plate 2 is fixed on the hollow cylinder to form a sealed hollow cylinder;

[0045] The standard segment 1 is a hollow semi-cylindrical structure, which includes five layers of hollow chambers, and the five layers of hollow chambers are arranged from outside to inside along the arc-shaped section of the hollow semi-cylindrical structure, namely, a first chamber, a second chamber, a third chamber, a fourth chamber and a fifth chamber;

[0046] The first chamber, the second chamber and the fifth chamber are all vacuum insulation layers, and the third chamber and the fourth chamber are both filled with a mixture of insulation materials;

[0047] The first to fourth chambers are used to achieve the function of heat preservation and moisture retention, and the fifth chamber is used to achieve the function of moisture retention.

[0048] In practical application, if Figure 1 As shown, the energy-saving and environmentally friendly integrated curing device for round bridge pier concrete includes a plurality of standard segments 1, connecting flanges and a top cover plate 2; wherein, the plurality of standard segments 1 are surrounded by a plurality of connecting flanges to form a hollow cylinder that wraps the round bridge pier, and the top cover plate 2 is fixed to the top of the standard segments 1 through a plurality of connecting flanges to form a sealed hollow cylinder, and silicone sealing rubber cotton insulation materials are embedded between the plurality of connecting flanges, and are connected into a tight whole by threads, so that the curing device can completely wrap the round bridge pier.

[0049] Furthermore, the standard segment 1 is a hollow semi-cylindrical structure, such as Figure 2 and Figure 3As shown, the hollow semi-cylindrical structure includes five layers of hollow chambers, and the five layers of hollow chambers are arranged from outside to inside along the arc-shaped section of the hollow semi-cylinder, namely the first chamber, the second chamber, the third chamber, the fourth chamber and the fifth chamber, wherein the first chamber, the second chamber and the fifth chamber are all vacuum insulation layers, and the third chamber and the fourth chamber are both filled with a mixture of insulation materials. When used, the heat absorbing partition parts of the first chamber and the second chamber are implemented with organic composite light-transmitting panels, so that the sun's radiant heat energy can be fully received, and the heat is transferred to the third chamber and the fourth chamber for insulation through the dark light-absorbing panel material on the third chamber and the fourth chamber, and the absorption and transfer of heat will not be prevented due to the filling of the third chamber and the fourth chamber with a mixture of insulation materials. Finally, the solar radiation heat energy is transferred to the round pier column of the bridge through the fifth chamber to achieve heating and curing of the concrete of the round pier column of the bridge. The heat energy generated by the hydration of cement in the concrete of the round pier column of the bridge is blocked by the third chamber and the fourth chamber to prevent leakage. At the same time, the fifth chamber is used to moisturize the concrete of the round pier column, thereby ensuring that the mixing water inside the concrete is not lost. The energy-saving and environmentally friendly integrated curing device for the concrete of the round pier column of the bridge described in this embodiment does not require the aid of an external heating device, and can achieve the curing of the concrete of the round pier column of the beam by using the solar radiation heat energy and the heat energy generated by the hydration of cement in the concrete, achieving zero curing energy cost, saving energy and achieving high environmental protection. Furthermore, it can also solve the problem of shrinkage cracks caused by uneven heating temperature and excessive drying that is not conducive to the increase of concrete strength when the concrete of the round pier column of the bridge is heated by heating devices such as hot air guns.

[0050] Implementation Method 2: See Figure 3 This embodiment is described as an example of the standard segment 1 in the energy-saving and environmentally friendly integrated curing device for concrete of a bridge round pier column described in the first embodiment;

[0051] The partitions of the five-layer hollow chamber of the standard segment 1 are arranged from outside to inside as a first partition 11, a second partition 12, a third partition 13, a fourth partition 14 and a fifth partition 15;

[0052] The first partition 11, the second partition 12 and the fifth partition 15 are implemented by organic composite light-transmitting plates;

[0053] The third partition plate 13 and the fourth partition plate 14 are implemented by dark light absorbing plates, and a light-transmitting and heat-insulating film is provided on the dark light absorbing plate of the third partition plate 13 to achieve one-way light transmission and one-way heat insulation functions.

[0054] In practical application, if Figure 3As shown, the partitions between the five layers of hollow chambers are the first partition 11, the second partition 12, the third partition 13, the fourth partition 14 and the fifth partition 15 from the outside to the pier column; wherein, the first partition 11, the second partition 12 and the fifth partition 15 are implemented by organic composite light-transmitting plates, so that the first chamber and the second chamber can receive the solar radiation heat energy, and the solar radiation heat energy is transferred to the third chamber and the fourth chamber through the third partition 13 and the fourth partition 14, which is used to achieve the heat preservation function, and at the same time, the third partition 13 and the fourth partition 14 are implemented by dark light-absorbing plates, which can fully absorb heat, and will not prevent the absorption and transfer of heat due to the mixture of heat-insulating materials filled in the third chamber and the fourth chamber. And the dark light-absorbing plate of the third partition 13 is provided with a light-transmitting heat-insulating film, which is used to absorb light without reflecting light, to achieve one-way light transmission and one-way heat insulation functions, and prevent the absorbed heat from being dissipated again. The fifth partition 15 transfers the heat energy generated by cement hydration in the concrete of the round pier column of the bridge to the third chamber and the fourth chamber for temperature isolation.

[0055] Implementation method three, see Figure 3 This embodiment is described as an example of the standard segment 1 in the energy-saving and environmentally friendly integrated curing device for concrete of a bridge round pier column described in the first embodiment;

[0056] The standard segment 1 also includes a segment cover 16;

[0057] The segment cover 16 is provided with a groove, so that the end plates of the partition plates of the five-layer hollow chamber are inserted into the groove of the segment cover 16 to form the five-layer hollow chamber.

[0058] In practical application, if Figure 3 As shown, the end plates of the first partition 11, the second partition 12, the third partition 13, the fourth partition 14 and the fifth partition 15 are designed with convex plates, and the segment cover 16 is provided with grooves, so that the end plates of the partitions of the five-layer hollow chamber are inserted into the grooves on the segment cover 16 to form five-layer hollow chambers, and the groove gaps are sealed with silicone rubber cotton.

[0059] Embodiment 4: This embodiment is an example of the thickness of the first chamber, the second chamber, the third chamber, the fourth chamber and the fifth chamber in the energy-saving and environmentally friendly integrated curing device for concrete of a bridge round pier column described in Embodiment 1;

[0060] The thickness of the first chamber, the second chamber and the fifth chamber are all 20 mm;

[0061] The thickness of the third chamber and the fourth chamber are both 50 mm.

[0062] In actual application of this embodiment, the thickness of the fifth chamber is set to 20mm, so that a 20mm thick vacuum buffer layer is formed between the insulation layer and the concrete pier column, so that the mixing water volatilized from the pier column will not be absorbed by the insulation material, so as to ensure that the surface of the pier column is always in a wet state, thus ensuring the continuous supply of hydration water required by the concrete during the strength growth process. That is, the function of both heat preservation and moisture retention is achieved through the 20mm thick space, compared with the prior art that usually places the insulation material close to the surface of the round pier column concrete, resulting in a lack of humidity in the concrete during the strength growth process, resulting in poor curing and heat preservation effects and slow concrete strength growth.

[0063] Furthermore, the prior art places the thermal insulation material in direct contact with the wet pier column, and its thermal conductivity increases by nearly 20 times after being damp, that is, the hydration heat loss rate released by the hydration of the pier column concrete increases by nearly 20 times. The use of the concrete energy-saving and environmentally friendly integrated curing device described in this embodiment can increase the thermal insulation efficiency by 20 times.

[0064] Furthermore, the 20 mm interval described in this embodiment also ensures the convenience of assembling the integrated curing device after the pier column formwork is removed, avoiding the problem of easy obstruction during assembly of the integrated curing device due to too small a gap, thereby greatly improving the efficiency of assembling the integrated curing device.

[0065] Embodiment 5: This embodiment is an example of the thermal conductivity of the first to fifth chambers in the energy-saving and environmentally friendly integrated curing device for concrete of a bridge round pier column described in Embodiment 1;

[0066] The thermal conductivity of the third chamber and the fourth chamber is smaller than that of the first chamber, the second chamber and the fifth chamber.

[0067] In actual application of this embodiment, the thermal conductivity of the third chamber and the fourth chamber is smaller than that of the first chamber, the second chamber and the fifth chamber, so that the heat energy between the concrete pier and the concrete curing device will not be dissipated through the third chamber and the fourth chamber, thereby achieving high-efficiency thermal insulation.

[0068] Embodiment 6: This embodiment is an example of the thermal insulation material mixture in the energy-saving and environmentally friendly integrated curing device for concrete of a bridge round pier column described in Embodiment 5;

[0069] The thermal insulation material mixture comprises organic thermal insulation material and inorganic thermal insulation material;

[0070] The particle size gradation of the organic thermal insulation material is less than 0.3 mm, and the internal porosity of the particles is greater than 50%, accounting for 67%;

[0071] The particle size gradation of the inorganic thermal insulation material is less than 0.15 mm, and the porosity inside the particles is greater than 50%, accounting for 33%.

[0072] In actual application of this embodiment, the insulation material mixture includes organic insulation material and inorganic insulation material, wherein the organic insulation material can be selected from black polystyrene particles, and the particle size gradation of the organic insulation material is less than 0.3mm single particle gradation, accounting for 67%; the inorganic insulation material is black glass wool particles, and its particle size gradation is less than 0.15mm single particle gradation, accounting for 33%; the internal porosity of the two insulation material particles is greater than 50%, and the void ratio between the two insulation material particles is greater than 50%, so that the thermal conductivity of the third chamber and the fourth chamber after filling with the mixed insulation material is less than the thermal conductivity of the first chamber, the second chamber, and the fifth chamber, so that the heat energy between the concrete pier and the concrete curing device will not be dissipated through the third chamber and the fourth chamber; at the same time, the proportions of organic insulation material and inorganic insulation material are 67% and 33% respectively, which can achieve a superimposed insulation effect, greatly improving the insulation efficiency while also improving the integrity, rigidity and strength of the integrated curing device.

[0073] During the period of high ambient temperature in summer, a greenhouse effect will be formed inside the integrated curing device, resulting in high internal temperature and humidity. In this season, when the highest air temperature during the day is 25±5℃, the surface temperature of the pier column concrete can be between 40 and 60℃, and the humidity is greater than 90%RH; when the lowest air temperature at night is 15±5℃, the surface temperature of the pier column concrete can still be maintained at around 20 to 30℃, and the humidity is greater than 90%RH. The strength of concrete grows rapidly in this season, which can greatly shorten the curing time of concrete. The strength of the pier column concrete can reach the design strength in about 3d, greatly improving the curing efficiency of the pier column concrete. At the turn of spring and summer, late autumn and early winter, when the lowest air temperature is between -8 and 10℃, and the daily average temperature is between 5 and 15℃, the integrated curing device can be used to cure the pier column without any form of heating of the pier column concrete, and the compressive strength can reach the design strength in 5d to 10d. In this season, when the highest air temperature during the day is 10±5℃, the surface temperature of the pier column concrete can reach about 20-30℃, and the humidity is greater than 90%RH; when the lowest air temperature at night is between -8±5℃, the surface temperature of the pier column concrete can still be maintained at about 10-20℃, and the humidity is greater than 90%RH. The temperature and humidity conditions required for concrete hydration can be fully met, and the strength can be guaranteed.

[0075] The organic thermal insulation material is black polystyrene particles; the inorganic thermal insulation material is black glass wool particles.

[0076] Embodiment 8: This embodiment is an example of the materials for the connecting flange and the top cover plate in the energy-saving and environmentally friendly integrated curing device for concrete round pier columns of bridges described in Embodiment 1;

[0077] The materials of the connecting flange and the top cover are both organic composite light-transmitting plates;

[0078] In actual application of this embodiment, the material connecting the flange and the top cover plate is both made of an organic composite light-transmitting plate, and the thickness of the organic composite light-transmitting plate is 6 mm.

[0079] Implementation method 9: See Figure 4 This embodiment is described as an example of the top cover plate 2 in the energy-saving and environmentally friendly integrated curing device for concrete round pier columns of a bridge described in Embodiment 8;

[0080] The top cover plate 2 is a hollow cylindrical structure, and the internal structure of the hollow cylinder is the same as the internal structure of the standard segment 1 .

[0081] In practical application, if Figure 4 As shown, the top cover plate 2 is a hollow cylindrical structure, and the hollow cylinder is arranged from the outside to the inside as a first chamber, a second chamber, a third chamber, a fourth chamber and a fifth chamber; the first chamber, the second chamber and the fifth chamber are all vacuum insulation layers, and the third chamber and the fourth chamber are both filled with a mixture of insulation materials; so that the top cover plate 2 can achieve the same function as the standard segment 1.

[0082] Embodiment 10: This embodiment is an example of the height of the standard segment 1 in the energy-saving and environmentally friendly integrated curing device for concrete of a bridge round pier column described in Embodiment 1;

[0083] The height of the standard segment 1 is 2 m.

[0084] Embodiment 11. This embodiment provides an energy-saving and environmentally friendly integrated curing method for round pier concrete of a bridge. The curing method is implemented based on an energy-saving and environmentally friendly integrated curing device for round pier concrete of a bridge described in any one of Embodiments 1 to 10. The curing method is:

[0085] Step 1: When pouring pier column concrete in summer, choose a period of high temperature during the day to remove the pier column formwork. Immediately after removing the formwork, start from the top of the pier column and wrap the pier column concrete surface in sections with high-strength insulation felt, and then soak the high-strength insulation felt with water. If the temperature at the construction site meets the conditions for water curing, the pier column concrete surface can be wetted with clean water that is higher than or equal to the ambient temperature, and then the pier column concrete surface can be tightly wrapped in sections with high-strength insulation felt.

[0086] Step 2: After fixing the high-strength thermal insulation felt, immediately assemble the integrated concrete curing device in sections on the outside of the high-strength thermal insulation felt.

[0087] Step 3: When pouring pier column concrete at the turn of spring and summer, or in late autumn and early winter, also choose a period with higher daytime temperature to remove the pier column formwork, and then follow the above steps.

[0088] Step 4. Before the curing period, the integrated concrete curing device should be checked regularly and carefully. If any air leakage is found in the integrated concrete curing device, it should be dealt with in time to ensure that the device is always in a good state of thermal insulation and moisturizing.

[0089] Step 5: While pouring the pier column concrete, more than two groups of specimens cured under the same conditions should be made and placed inside the integrated curing device. Under the pier column, a small movable sealed window should be reserved in the lowest segment of the device to facilitate the placement of concrete specimens cured under the same conditions for compressive strength testing.

[0090] Step 6. When the compressive strength of the concrete specimens cured under the same conditions meets the design requirements, the concrete integrated curing device can be carefully removed and properly stored and transported for recycling and curing.

[0091] Step 7. The above operation process should be smooth and well organized. The demoulding machinery and equipment, personnel, and the integrated curing device for concrete, high-strength insulation felt, curing water, and mechanical equipment for assembling the curing device should be fully organized, trained, and rehearsed. In summer, the entire operation process should not exceed 2.5 hours; in the turn of spring and summer, late autumn and early winter, the entire operation process should not exceed 1.5 hours.

[0092] In actual application, this embodiment is formed by enclosing a hollow cylinder through several standard segments, and the top cover plate is fixed on the hollow cylinder to form a sealed hollow cylinder, so that the curing device can completely wrap the round pier of the bridge. Furthermore, the standard segment is a hollow semi-cylindrical structure with five layers of hollow chambers, and the first, second and fifth chambers of the five layers of hollow chambers are all vacuum insulation layers, and the third and fourth chambers are filled with a mixture of insulation materials, so that an insulating, heat-insulating and moisture-retaining cavity is formed between the concrete pier and the concrete curing device, and the cavity is in a vacuum state, and there is almost no heat exchange with the outside world. Without any artificial heat source, the heat energy released by cement hydration in the pier concrete is utilized, and the radiant heat solar energy of the sun during the day is gathered. With the superposition of the two kinds of heat energy, during summer construction, the internal temperature of the pier concrete can reach about 40℃~60℃ during the day, and the humidity is greater than 90%RH; when the lowest air temperature at night is 15±5℃, the surface temperature of the pier concrete can still be maintained at about 20~30℃, and the humidity is greater than 90%RH; at the turn of spring and summer, late autumn and early winter, when the lowest air temperature is between -8~10℃ and the daily average temperature is between 5~15℃, the integrated curing device can be used to cure the pier, so that the pier concrete does not need to be heated in any form, and the compressive strength of 5d~10d can reach the design strength. In this season, when the highest air temperature during the day is 10±5℃, the surface temperature of the pier column concrete can reach about 20-30℃, and the humidity is greater than 90%RH; when the lowest air temperature at night is -8±5℃, the surface temperature of the pier column concrete can still be maintained at about 10-20℃, and the humidity is greater than 90%RH. The temperature and humidity conditions required for concrete hydration can be fully met, and the compressive strength of the pier column concrete can fully reach or even exceed the design strength.
