Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to a method for curing concrete piers and cap beams. Background Technology

[0002] As important components of bridge structure, cap beams and piers bear enormous loads and ensure the stability and safety of the bridge. In the construction process of bridges, cap beams and piers are commonly constructed using the cast-in-place method. The cast-in-place method involves erecting scaffolds on top of the piers, then tying reinforcing bars, setting up formwork, and finally pouring concrete.

[0003] After the cap beams and piers are poured, they need to gradually harden and increase in strength through hydration. This process requires suitable temperature and humidity conditions. The purpose of curing is to artificially create these conditions so that the concrete can harden normally or more quickly. Inaccurate temperature control of the cap beams and piers during the curing process often leads to a series of problems, with cracking being one of the most common and serious. During the strength development process, the concrete in the cap beams and piers generates high heat at its center, reaching temperatures up to 60°C. If precise curing is not carried out based on the accurate internal temperature, the temperature difference between the concrete center and surface will be too large, leading to thermal cracks. Thermal cracks not only affect the appearance quality of the cap beams and piers but also reduce their integrity and durability. Summary of the Invention

[0004] This invention provides a method for curing concrete piers and cap beams. Temperature sensors are pre-embedded in the cap beams and piers to collect internal temperatures and generate curing parameters based on temperature changes to cure the piers and cap beams, thus avoiding cracks caused by inaccurate temperature control during the curing process.

[0005] A method for curing concrete piers and cap beams includes the following steps:

[0006] Based on the construction parameters, obtain the temperature measurement points for the piers and cap beams;

[0007] Based on the above temperature measurement points, temperature measuring devices should be installed at the temperature measurement points during the process of tying the steel reinforcement cage.

[0008] After the steel reinforcement cage is tied, pour the concrete.

[0009] The temperature collected by the thermometer is obtained, and the maintenance parameters are obtained by combining the collected temperature with the parameters of the pier and the cap beam.

[0010] Based on the calculated maintenance parameters, the piers and cap beams are maintained.

[0012] Furthermore, the positioning frame is provided with an upper temperature measurement zone and a lower temperature measurement zone, wherein an isolation zone is provided between the upper temperature measurement zone and the lower temperature measurement zone.

[0014] Furthermore, the upper temperature measurement zone has temperature measurement chambers a, b, and c arranged side by side, and the upper temperature measurement mechanism includes thermocouples a, b, and c. The temperature measuring ends of thermocouples a, b, and c are respectively fixed inside the temperature measurement chambers a, b, and c by positioning plates.

[0015] Furthermore, the spacing between the temperature measuring ends of thermocouple a, thermocouple b, and thermocouple c is set to be equal.

[0016] Furthermore, the lower temperature measurement zone has temperature measurement chambers d, e, and f arranged side by side, and the lower temperature measurement mechanism includes thermocouples d, e, and f. The temperature measuring ends of thermocouples d, e, and f are respectively fixed inside the temperature measurement chambers d, e, and f by positioning plates.

[0017] Furthermore, the spacing between the temperature measuring ends of thermocouples d, e, and f is set to be equal, and the spacing between the temperature measuring ends of thermocouples d, e, and f and the temperature measuring ends of thermocouples a, b, and c is set to be equal.

[0018] Furthermore, the connector includes a turnbuckle and a snap fastener, one end of the turnbuckle is connected to the corner of the positioning frame, and the other end of the turnbuckle is connected to the snap fastener.

[0019] Furthermore, the signal output terminals of thermocouples a, b, c, d, e, and f are communicatively connected to the signal input terminal of the controller, and the controller calculates maintenance parameters based on the thermocouple signals.

Detailed Implementation

[0034] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0035] like Figure 1 As shown in the figure, this embodiment of the invention provides a method for curing concrete piers and cap beams, including the following steps:

[0036] S1, Based on the construction parameters, obtain the temperature measurement points of the piers and cap beams;

[0037] include:

[0038] S11. Based on the construction parameters, collect the concrete material properties and input them into the simulation system to set the physical parameters of the concrete.

[0039] S12, set the pouring temperature and pouring speed, and use the finite element analysis method for simulation;

[0040] S13, Based on the above settings, the temperature changes of the pier and cap beam components during the casting process are solved step by step;

[0041] S14, extract the temperature concentration area and calculate the temperature measurement points covering the temperature concentration area;

[0042] S15 outputs the temperature measurement point.

[0043] S2, Based on the above temperature measurement points, install temperature measuring devices at the temperature measurement points during the process of tying the steel reinforcement cage.

[0044] like Figure 2 As shown, in one embodiment, the temperature sensor includes a positioning frame 1 and a temperature measuring mechanism disposed therein. Eight connectors 5 are provided at the corners of the positioning frame 1 for connecting with the steel reinforcement skeleton of the pier and the cap beam.

[0045] like Figure 3 As shown, in another embodiment, the temperature sensor includes a positioning frame 1 and a temperature measuring mechanism disposed therein. Four connectors 5 are provided at the corners of the positioning frame 1, wherein two connectors 5 are located on the same side of one side of the temperature measuring section 12 below the positioning frame 1, and two connectors 5 are located on the same side of the other side of the temperature measuring section 11 above the positioning frame 1, for connecting with the steel reinforcement skeleton of the pier and the cap beam.

[0046] The number of connectors 5 can be increased or decreased according to actual needs. Connectors 5 are used to fix the positioning frame 1 on the steel reinforcement skeleton of the pier and cap beam to prevent the positioning frame 1 from shifting during the pouring and vibration process.

[0047] like Figure 4 As shown, connector 5 includes turnbuckle 51 and snap fastener 52. One end of turnbuckle 51 is connected to the corner of positioning frame 1, and the other end of turnbuckle 51 is connected to snap fastener 52.

[0048] During installation, after connecting the buckle 52 to the steel reinforcement cage of the pier and cap beam, the length of the turnbuckle 51 is adjusted to fix the positioning frame 1 at the temperature measuring point, so as to prevent the positioning frame 1 from shifting during the pouring and vibration process.

[0049] S3, after the steel reinforcement cage is tied, pour concrete.

[0050] S4: Obtain the temperature collected by the thermometer, and obtain the maintenance parameters based on the collected temperature and the parameters of the pier and cap beam.

[0051] like Figures 1-2 As shown, the positioning frame 1 is provided with an upper temperature measurement zone 11 and a lower temperature measurement zone 12. An isolation zone 13 is provided between the upper temperature measurement zone 11 and the lower temperature measurement zone 12. The upper temperature measurement zone 11 has temperature measurement chambers a111, b112 and c113 arranged side by side, and the lower temperature measurement zone 12 has temperature measurement chambers d121, e122 and f123 arranged side by side.

[0052] The upper temperature measuring mechanism 3 includes thermocouple a31, thermocouple b32 and thermocouple c33. The temperature measuring ends of thermocouple a31, thermocouple b32 and thermocouple c33 are fixed inside temperature measuring chamber a111, temperature measuring chamber b112 and temperature measuring chamber c113 respectively by positioning plate 2.

[0053] The lower temperature measuring mechanism 4 includes thermocouples d41, e42, and f43. The temperature measuring ends of thermocouples d41, e42, and f43 are respectively fixed inside temperature measuring chambers d121, e122, and f123 by positioning plates 2.

[0054] like Figures 5-8 As shown, the temperature measuring cavities a111, b112, c113, d121, e122, and f123 have the same dimensions. During the arrangement of thermocouples a31, b32, c33, d41, e42, and f43, their measuring ends are respectively placed in the aforementioned temperature measuring cavities a, b112, c113, d121, and f123. Inside the temperature measuring cavity e122 and the temperature measuring cavity f123, the spacing between the temperature measuring ends of thermocouples a31, b32 and c33 is set to be equal, the spacing between the temperature measuring ends of thermocouples d41, e42 and f43 is set to be equal, and the spacing between the temperature measuring ends of thermocouples d41, e42 and f43 and the temperature measuring ends of thermocouples a31, b32 and c33 is set to be equal.

[0055] The function of the isolation zone 13 is to isolate the upper temperature measurement zone 11 from the lower temperature measurement zone 12, so that the temperatures measured by the upper temperature measurement mechanism 3 and the lower temperature measurement mechanism 4 are different.

[0056] S5. Based on the calculated maintenance parameters, the piers and cap beams are maintained.

[0057] like Figure 8 As shown, the signal output terminals of thermocouples a31, b32, c33, d41, e42, and f43 are communicatively connected to the signal input terminal of controller 6. Controller 6 calculates maintenance parameters based on the thermocouple signals.

[0058] The controller 6 is equipped with a signal acquisition module 61, a temperature distribution calculation module 62, and a maintenance parameter calculation module 63.

[0059] The signal acquisition module 61 acquires the temperatures collected by thermocouples a31, b32, c33, d41, e42, and f43.

[0060] The temperature distribution calculation module 62 calculates the temperature of each area of ​​the concrete pier and cap beam based on the temperatures collected by thermocouples a31, b32, c33, d41, e42, and f43.

[0061] The steps include:

[0062] Construct a three-dimensional model and determine the spatial coordinates of thermocouples a31, b32, c33, d41, e42, and f43 based on the structure of positioning frame 1.

[0063] The first temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouples a31, b32, and c33.

[0064] The second temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouples d41, e42, and f43.

[0065] The third temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple a31 and thermocouple d41.

[0066] The fourth temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple a31 and thermocouple e42.

[0067] The fifth temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple a31 and thermocouple f43.

[0068] The sixth temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple b32 and thermocouple d41.

[0069] The seventh temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple b32 and thermocouple e42.

[0070] The eighth temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple b32 and thermocouple f43.

[0071] The ninth temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple C33 and thermocouple D41.

[0072] The tenth temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple C33 and thermocouple E42.

[0073] The eleventh temperature gradient distribution inside the concrete pier and cap beam is calculated using the temperature difference between thermocouple C33 and thermocouple F43.

[0074] The temperature distribution calculation module 62 uses the first to eleventh temperature gradients mentioned above to predict the internal temperature change trend of the concrete components of the cap beam and pier, thus obtaining the temperature distribution and temperature change of the concrete components of the cap beam and pier.

[0075] The curing parameter calculation module 63 monitors the temperature of the concrete components of the cap beam and pier column based on the calculated temperature distribution and temperature changes, and generates curing parameters, including: curing time, curing temperature, curing humidity, curing water quality, curing method (e.g., when the internal temperature of the concrete reaches 60 degrees, it provides parameters for internal cooling (cooling temperature, cooling time) and surface insulation (insulation blanket thickness, foam board thickness) to avoid large internal and external temperature differences that could cause cracking).

[0076] This invention collects internal temperatures by pre-embedding temperature sensors in the cap beam and pier columns, and generates maintenance parameters based on temperature changes to maintain the pier columns and cap beams, thus avoiding cracks caused by inaccurate temperature control during the maintenance process.

[0077] It should be noted that the specific models and specifications of controller 6 and thermocouples a31 to f43 need to be selected and determined according to the actual specifications of the device.
