Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a method for maintaining a concrete pier column and a cap beam. Background Art

[0002] As important components of the bridge structure, the cap beam and piers bear huge loads and ensure the stability and safety of the bridge. During the construction of the bridge, the cap beam and piers are commonly cast in situ. The cast-in-situ method is to set up a support on the top of the pier, then tie the steel bars, support the formwork, and finally pour the concrete.

[0003] After the cap beam and pier are poured, they need to gradually harden and increase their strength through hydration reaction. This process requires suitable temperature and humidity conditions. The purpose of curing is to artificially create such conditions so that the concrete can harden normally or accelerate. During the concrete curing process, inaccurate temperature control of the cap beam and pier often leads to a series of problems, among which cracks are one of the most common and serious problems. During the strength generation process of the concrete of the cap beam and pier, high heat will be generated in the center, and the temperature can reach 60°C. If the concrete is not accurately cured according to the accurate internal temperature, the temperature difference between the center and the surface of the concrete will be too large, resulting in the generation of temperature difference cracks. Temperature difference cracks not only affect the appearance quality of the cap beam and pier, but also reduce their integrity and durability. Summary of the invention

[0004] An embodiment of the present invention provides a method for curing concrete piers and cap beams, in which temperature sensors are embedded in the cap beams and piers to collect the internal temperature and generate curing parameters based on temperature changes to cure the piers and cap beams, thereby avoiding the problem of cracks caused by inaccurate temperature control during the curing process.

On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] like Figure 1 As shown, an embodiment of the present invention provides a method for curing concrete piers and cap beams, comprising the following steps:

[0036] S1, obtain the temperature measurement points of the pier and cap beam according to the construction parameters;

[0037] include:

[0038] S11, according to the construction parameters, input the collected concrete material properties into the simulation system to set the physical parameters of the concrete;

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

[0041] S14, taking out the temperature concentration area, and calculating the temperature measurement points covering the temperature concentration area;

[0042] S15, output temperature measurement point.

[0043] S2. According to the above-mentioned temperature measuring points, a temperature measuring device is installed at the temperature measuring point during the process of tying the steel bar skeleton.

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

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

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

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

[0048] During the installation process, after being connected to the steel frame of the pier column and the cap beam through the buckle 52, the length of the basket bolt 51 is adjusted so that the positioning frame 1 is fixed at the temperature measuring point to avoid displacement of the positioning frame 1 during the pouring and vibration process.

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

[0050] S4, obtaining the temperature collected by the temperature sensor, and obtaining the maintenance parameters according to the collected temperature combined with the parameters of the pier and the cap beam.

[0051] like Figures 1-2 As shown, an upper temperature measuring interval 11 and a lower temperature measuring interval 12 are arranged in the positioning frame 1, wherein an isolation interval 13 is arranged between the upper temperature measuring interval 11 and the lower temperature measuring interval 12, wherein the upper temperature measuring interval 11 has a temperature measuring cavity a111, a temperature measuring cavity b112 and a temperature measuring cavity c113 arranged side by side, and the lower temperature measuring interval 12 has a temperature measuring cavity d121, a temperature measuring cavity e122 and a temperature measuring cavity f123 arranged side by side.

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

In the process of arranging thermocouple a31, thermocouple b32, thermocouple c33, thermocouple d41, thermocouple e42 and thermocouple f43, their temperature measuring ends are respectively placed in the above-mentioned temperature measuring chamber a, temperature measuring chamber b112, temperature measuring chamber c113, temperature measuring chamber d121, temperature measuring chamber e122 and temperature measuring chamber f123. Inside the temperature cavity e122 and the temperature measuring cavity f123, the spacing between the temperature measuring ends of thermocouple a31, thermocouple b32 and thermocouple c33 is set to be equal, the spacing between the temperature measuring ends of thermocouple d41, thermocouple e42 and thermocouple f43 is set to be equal, and the spacing between the temperature measuring ends of thermocouple d41, thermocouple e42 and thermocouple f43 and the temperature measuring ends of thermocouple a31, thermocouple b32 and thermocouple c33 is set to be equal.

[0055] The isolation interval 13 is used to isolate the upper temperature measuring interval 11 from the lower temperature measuring interval 12 , so that there is a difference in temperature between the upper temperature measuring mechanism 3 and the lower temperature measuring mechanism 4 .

[0056] S5. Maintain the piers and cap beams according to the calculated maintenance parameters.

[0057] like Figure 8 As shown, the signal output ends of thermocouple a31, thermocouple b32, thermocouple c33, thermocouple d41, thermocouple e42 and thermocouple f43 are communicatively connected to the signal input end of the controller 6, and the controller 6 calculates the curing parameters according to the signals of the thermocouples.

[0058] The controller 6 is provided 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 obtains the temperatures collected by thermocouple a31 , thermocouple b32 , thermocouple c33 , thermocouple d41 , thermocouple e42 , and thermocouple f43 .

[0060] The temperature distribution calculation module 62 calculates the temperature of each area of ​​the earth mound column and the cap beam according to the temperatures collected by thermocouple a31, thermocouple b32, thermocouple c33, thermocouple d41, thermocouple e42, and thermocouple f43.

[0061] The steps include:

[0062] Construct a three-dimensional model, and determine the spatial coordinates of thermocouple a31, thermocouple b32, thermocouple c33, thermocouple d41, thermocouple e42, and thermocouple f43 according to the structure of the positioning frame 1;

[0063] Calculate the first temperature gradient distribution inside the earth mound column and the cap beam by using the temperature difference between the thermocouple a, the thermocouple b32 and the thermocouple c33;

[0064] The second temperature gradient distribution inside the earth mound column and the cap beam is calculated using the temperature difference among the thermocouple d41, the thermocouple e42 and the thermocouple f43;

[0065] The third temperature gradient distribution inside the earth mound column and the cap beam is calculated using the temperature difference between the thermocouple a and the thermocouple d41;

[0066] The fourth temperature gradient distribution inside the mound column and the cap beam is calculated using the temperature difference between the thermocouple a and the thermocouple e42;

[0067] The fifth temperature gradient distribution inside the mound column and the cap beam is calculated using the temperature difference between the thermocouple a and the thermocouple f43;

[0068] The sixth temperature gradient distribution inside the earth mound column and the cap beam is calculated using the temperature difference between the thermocouple b and the thermocouple d41;

[0070] The eighth temperature gradient distribution inside the earth mound column and the cap beam is calculated using the temperature difference between the thermocouple b and the thermocouple f43;

[0071] The ninth temperature gradient distribution inside the earth mound column and the cap beam is calculated using the temperature difference between the thermocouple c and the thermocouple d41;

[0072] The temperature difference between the thermocouple c and the thermocouple e42 is used to calculate the tenth temperature gradient distribution inside the earth mound column and the cap beam;

[0073] The temperature difference between the thermocouple c and the thermocouple f43 is used to calculate the eleventh temperature gradient distribution inside the earth mound column and the cap beam;

[0075] The maintenance parameter calculation module 63 monitors the temperature of the cap beam and pier column concrete components according to the calculated temperature distribution and temperature change of the cap beam and pier column concrete components, and generates maintenance parameters, wherein the maintenance parameters include: maintenance time, maintenance temperature, maintenance humidity, water quality of maintenance water, maintenance method (for example, when the internal temperature of the concrete reaches 60 degrees, the internal cooling (cooling temperature, cooling time) and surface insulation parameters (insulation blanket thickness, foam board thickness) are given to avoid large temperature difference between the inside and the outside, which may cause cracking).

[0076] The present invention embeds temperature detectors in the cap beam and the pier to collect the internal temperature and generates maintenance parameters according to the temperature change to maintain the pier and the cap beam, thereby avoiding the problem of cracks caused by inaccurate temperature control during the maintenance process.
