Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, and in particular to a construction method for controlling the pouring height of underwater bridge pile foundation concrete using an empirical method. Background Art

[0002] In bridge construction, pile foundations are a crucial component supporting the structure. Their stability and bearing capacity are directly related to the safety and service life of the bridge. The construction environment for underwater bridge pile foundations is complex, especially in conditions of turbulent currents or deep water. Therefore, effectively controlling the concrete pouring height of underwater bridge pile foundations to ensure their quality and stability has become a key issue in bridge construction. Traditional control methods often rely on the experience and judgment of construction workers, but this approach is subject to significant uncertainty and struggles to ensure accurate and consistent pouring heights.

[0003] Chinese patent application publication number CN106498935A discloses a method for pouring underwater concrete for bored piles, comprising the following steps: installing a steel retaining ring at the bored pile foundation pit; extending a discharge pipe of a concrete hopper into the bored pile foundation pit, with a distance A between the lower end of the discharge pipe and the pit bottom remaining; the distance A being 8%-15% of the depth L of the bored pile foundation pit; opening the concrete hopper and discharging concrete to a height of 0.4-0.85A above the pit bottom; lifting the concrete hopper so that a distance B between the lower end of the discharge pipe and the pit bottom is 30%-50% of the depth L of the bored pile foundation pit; then opening the concrete hopper and discharging concrete to a height of 0.85B above the pit bottom; lifting the concrete hopper and discharging concrete multiple times until the concrete is discharged to the upper pit mouth, and curing to obtain bored pile concrete.

[0004] However, the prior art has the following problems: there is a lack of refined processing of the concrete pouring height construction process of the underwater bridge pile foundation, which leads to the problem of low efficiency of the concrete pouring height construction. Summary of the Invention

[0005] To this end, the present invention provides an empirical method for controlling the concrete pouring height of underwater bridge pile foundations, so as to overcome the problem that the prior art lacks refined processing of the concrete pouring height construction process of underwater bridge pile foundations, thereby resulting in low efficiency of concrete pouring height construction.

[0006] To achieve the above object, the present invention provides a construction method for controlling the pouring height of underwater bridge pile foundation concrete by an empirical method, comprising:

[0007] Acquire historical data of concrete pouring for underwater bridge pile foundations and real-time monitored hydrological data, wherein the historical data includes historical pouring height data, historical environmental data, and historical concrete status data;

[0008] Determining whether a historical pouring height setting is qualified based on the strength value of the historical concrete state data;

[0009] Determining the control method of concrete pouring height as layered pouring or segmented pouring based on the comprehensive characterization parameters of the historical environmental data;

[0010] Determining the eligibility of the control method based on the impact value of the real-time monitored hydrological data;

[0011] Under the condition that the control mode is determined to be unqualified, determining based on the difference between the influence value and the preset influence value whether to reduce the number of layers for layered pouring by a preset layer adjustment coefficient or to reduce the number of sections for segmented pouring by a preset section adjustment coefficient;

[0012] Determine whether the concrete quality is within a reasonable range based on the texture uniformity value of the concrete after pouring each layer or each section;

[0013] Under the condition that it is determined that the concrete quality is not within a reasonable range, the single pouring height is increased by the first preset single pouring height adjustment coefficient or the second preset single pouring height adjustment coefficient based on the ratio of the texture uniformity value to the preset texture uniformity value.

[0014] Furthermore, it is determined that the historical pouring height setting is qualified based on a comparison result that the strength value of the historical concrete state data is greater than or equal to a strength threshold.

[0015] Furthermore, based on the comparison result that the comprehensive characterization parameter of the historical environmental data is less than or equal to the preset comprehensive characterization parameter, it is determined that the control method of the concrete pouring height is layered pouring, and the single pouring height is determined to be 1.0m-1.5m, and the number of layers is the ratio of the total pouring height to the single pouring height of the layered pouring.

[0016] Furthermore, based on the comparison result that the comprehensive characterization parameter of the historical environmental data is greater than the preset comprehensive characterization parameter, it is determined that the control method of the concrete pouring height is segmented pouring, and the single pouring height is determined to be 1.6m-2.0m, and the number of segments is the ratio of the total pouring height to the single pouring height of the segmented pouring.

[0017] Furthermore, the control method is determined to be unqualified based on a comparison result that the influence value of the real-time monitored hydrological data is greater than a preset influence value.

[0018] Furthermore, based on the comparison result that the difference between the impact value and the preset impact value is less than or equal to the preset difference, it is determined to reduce the number of layers by a first preset layer adjustment coefficient, or to reduce the number of segments by a first preset segment adjustment coefficient.

[0019] Furthermore, based on the comparison result that the difference between the influence value and the preset influence value is greater than the preset difference, it is determined to reduce the number of layers by a second preset layer adjustment coefficient, or to reduce the number of segments by a second preset segment adjustment coefficient.

[0020] Furthermore, based on the comparison result that the texture uniformity value of the concrete after pouring each layer or each section is less than the preset texture uniformity value, it is determined that the quality of the concrete is not within a reasonable range.

[0021] Furthermore, based on a comparison result that the ratio of the texture uniformity value to the preset texture uniformity value is less than or equal to the preset ratio, it is determined that the single pouring height is increased by the first preset single pouring height adjustment coefficient.

[0022] Furthermore, based on a comparison result that the ratio of the texture uniformity value to the preset texture uniformity value is greater than the preset ratio, it is determined that the single pouring height is increased by a second preset single pouring height adjustment coefficient.

[0023] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention, through comprehensive historical and real-time monitoring data, carries out fine control of the pouring height of the concrete of the underwater bridge pile foundation, verifies the historical pouring height based on the historical concrete strength value, selects the pouring method according to the historical environmental data, uses the real-time monitoring hydrological data to verify the control method, monitors the texture uniformity value after pouring to ensure the quality of the concrete, and adjusts the single pouring height according to the ratio of the texture uniformity value to the preset texture uniformity value, thereby improving the accuracy of the concrete pouring height construction decision and the control ability of the concrete pouring quality, improving the overall construction efficiency and quality, and improving the efficiency of the concrete pouring height construction.

[0024] Furthermore, the present invention screens out qualified historical pouring height data through historical concrete strength values, and determines the control method of concrete pouring height accordingly, thereby improving the accuracy of construction, ensuring the stability of concrete strength and the construction efficiency of concrete pouring height, and in-depth analysis of historical data avoids the use of unqualified pouring height settings.

[0025] Furthermore, the present invention determines the eligibility of the control method through the influence value, and adjusts the concrete pouring height according to the difference between the influence value and the preset influence value when it is unqualified, thereby improving the accuracy of the concrete pouring construction and the accuracy of the concrete pouring height control method during the construction process, thereby improving the efficiency of the concrete pouring height construction.

[0026] Furthermore, the present invention evaluates the quality of concrete by comparing the concrete texture uniformity with a preset texture uniformity. If the quality does not meet the standard, the single pouring height is adjusted according to the ratio of the texture uniformity to the preset value, thereby improving the concrete pouring quality, ensuring the stability and consistency of the concrete quality, and improving the construction quality of underwater bridge pile foundations.

[0034] See also Figure 1 The flowchart of the construction method for controlling the concrete pouring height of underwater bridge pile foundation based on the empirical method is shown in the figure.

[0035] The embodiment of the present invention provides a construction method for controlling the pouring height of underwater bridge pile foundation concrete based on an empirical method, comprising:

[0036] Step S1, obtaining historical data of concrete pouring of underwater bridge pile foundations and real-time monitored hydrological data, wherein the historical data includes historical pouring height data, historical environmental data, and historical concrete status data;

[0037] Step S2, determining whether the historical pouring height setting is qualified based on the strength value of the historical concrete state data;

[0042] Step S7: Under the condition that it is determined that the concrete quality is not within a reasonable range, based on the ratio of the texture uniformity value to the preset texture uniformity value, determine whether to increase the single pouring height by the first preset single pouring height adjustment coefficient or the second preset single pouring height adjustment coefficient.

[0043] In the embodiment of the present invention, the historical pouring height data is a number of historical single pouring heights.

[0044] In an embodiment of the present invention, the historical environmental data further includes historical hydrological data and historical geological data. The historical hydrological data is a number of historical flow velocity data, and the historical geological data is a number of historical riverbed hardness and historical riverbed viscosity.

[0045] In the embodiment of the present invention, the historical concrete state data are a number of historical compressive strengths and historical tensile strengths.

[0046] In the embodiment of the present invention, the real-time monitored hydrological data is flow rate data, and the hydrological data is measured by a flow meter. There is no specific limitation, as long as the hydrological data can be measured.

[0047] In the embodiment of the present invention, the texture uniformity of the concrete is measured by an ultrasonic detector.

[0048] Specifically, the present invention controls the pouring height of underwater bridge pile foundation concrete in a refined manner by integrating historical and real-time monitoring data, verifies the historical pouring height based on historical concrete strength values, selects the pouring method based on historical environmental data, verifies the control method using real-time monitoring of hydrological data, monitors the texture uniformity value after pouring to ensure the quality of concrete, and adjusts the single pouring height according to the ratio of the texture uniformity value to the preset texture uniformity value, thereby improving the accuracy of concrete pouring height construction decisions and the ability to control concrete pouring quality, thereby improving overall construction efficiency and quality, and improving the efficiency of concrete pouring height construction.

[0049] See also Figure 2 The flow chart for determining whether the historical pouring height setting is qualified is shown below.

[0050] Specifically, the embodiment of the present invention determines whether the historical pouring height setting is qualified based on the comparison result of the strength value of the historical concrete state data and the strength threshold value of 0.92;

[0051] When the strength value is less than the strength threshold, it is determined that the historical pouring height setting is unqualified;

[0052] When the strength value is greater than or equal to the strength threshold, it is determined that the historical pouring height setting is qualified.

[0053] In the embodiment of the present invention, the strength threshold is 0.92, which is obtained by taking the average of several qualified strength values ​​of historical casting height settings, but the above value is not limited to this. Those skilled in the art can also adjust the value according to actual needs.

[0054] In the embodiment of the present invention, the historical pouring height data with unqualified historical pouring height settings are removed.

[0055] Specifically, the embodiment of the present invention calculates the intensity value according to the following formula, setting:

[0056]

[0057] in, Indicates the intensity value, is the historical compressive strength, is the historical average compressive strength, is the historical tensile strength, is the mean value of historical tensile strength, the historical compressive strength is obtained by performing compressive strength tests on concrete, and the historical tensile strength is obtained by performing tensile strength tests on concrete.

[0058] Specifically, the embodiment of the present invention determines the control method of the concrete pouring height based on the comparison result of the comprehensive characterization parameter of the historical environmental data and the preset comprehensive characterization parameter 0.87 under the condition that the historical pouring height setting is qualified;

[0059] When the comprehensive characterization parameter is less than or equal to the preset comprehensive characterization parameter, the control method of the concrete pouring height is determined to be layered pouring, and the single pouring height under this control method is determined to be 1.0m-1.5m, preferably 1.3m;

[0060] When the comprehensive characterization parameter is greater than the preset comprehensive characterization parameter, the control method of the concrete pouring height is determined to be segmented pouring, and the single pouring height under this control method is determined to be 1.6m-2.0m, preferably 1.8m.

[0061] In the embodiment of the present invention, the preset comprehensive characterization parameter value is 0.87, and the value range is 0-1, but the above value is not limited thereto, and those skilled in the art can also adjust the value according to actual needs.

[0062] In an embodiment of the present invention, the layered pouring is to wait for a preset time of 2 hours after pouring each layer of the underwater bridge pile foundation, and then pour the next layer. The segmented pouring is to place a steel cage and reinforce it when pouring each section of the underwater bridge pile foundation, and then pour concrete.

[0063] Specifically, the number of layers for layered pouring is determined based on the ratio of the total pouring height to the single pouring height. For example, if the total height of the pile foundation is 20m and the single pouring height is 1.5m, the number of layers is 13; the number of sections is the ratio of the total pouring height to the single pouring height. For example, if the total height of the pile foundation is 20m and the single pouring height is 2.0m, the number of sections is 10.

[0064] It can be understood that the single pouring height under the two control modes is the historical pouring height data with qualified historical pouring height settings.

[0065] Specifically, the embodiment of the present invention calculates the comprehensive characterization parameter according to the following formula, setting:

[0066]

[0067] in, represents the comprehensive characterization parameter, is the historical average flow rate, For the historical flow rate threshold, set =2.5m / s, is the historical average riverbed hardness, is the historical riverbed hardness threshold, set =15MPa, is the historical riverbed viscosity, is the historical riverbed viscosity threshold, set =1.8Pa.s.

[0068] Specifically, the present invention screens out qualified historical pouring height data through historical concrete strength values, and determines the control method of concrete pouring height accordingly, thereby improving the accuracy of construction, ensuring the stability of concrete strength and the construction efficiency of concrete pouring height, and in-depth analysis of historical data avoids the use of unqualified pouring height settings.

[0069] See also Figure 3 The flow chart for determining the eligibility of the control method is shown in the following figure.

[0070] Specifically, the embodiment of the present invention uses the control method of the concrete pouring height as an empirical method, and determines the eligibility of the control method based on the comparison result of the impact value of the real-time monitored hydrological data and the preset impact value of 0.78;

[0071] When the influence value is less than or equal to the preset influence value, it is determined that the control mode is qualified;

[0072] When the impact value is greater than a preset impact value, it is determined that the control mode is unqualified.

[0073] In the embodiment of the present invention, the preset influence value is 0.78, which is obtained by taking the average of the influence values ​​of several qualified control modes. However, the above value is not limited to this, and those skilled in the art can also adjust the value according to actual needs.

[0074] It is understandable that, when it is determined that the control method is qualified, the embodiment of the present invention pours the underwater bridge pile foundation concrete according to the control method.

[0075] Specifically, the embodiment of the present invention calculates the impact value according to the following formula, setting:

[0076]

[0077] in, Indicates the impact value, For real-time monitoring of flow rate, For The historical flow rate for the corresponding period, It is the ratio of the real-time temperature to the room temperature of 25°C, and the real-time temperature is detected by a thermometer.

[0078] Specifically, in the embodiment of the present invention, under the condition that the control method is determined to be unqualified, the control method of the concrete pouring height is determined according to the comparison result of the difference between the influence value and the preset influence value and the preset difference value of 0.55;

[0079] When the difference is less than or equal to the preset difference, it is determined to reduce the number of layers to a corresponding value using a first preset layer adjustment coefficient of 0.6, or to reduce the number of segments to a corresponding value using a first preset segment adjustment coefficient of 0.8;

[0080] When the difference is greater than the preset difference, it is determined to reduce the number of layers to a corresponding value using a second preset layer adjustment coefficient of 0.4, or to reduce the number of segments to a corresponding value using a second preset segment adjustment coefficient of 0.5;

[0081] In the embodiment of the present invention, the difference value is the difference between the influence value and the preset influence value, that is, the result of subtracting the preset influence value from the influence value.

[0082] In the embodiment of the present invention, the preset difference value is 0.55, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0083] In an embodiment of the present invention, the reduced number of layers is the product of the number of layers and the i-th preset layer adjustment coefficient, where i is 1 or 2, L1 is the first preset layer adjustment coefficient 0.6, and L2 is the second preset layer adjustment coefficient 0.4. It can be understood that the reduced number of layers should be an integer, and non-integer number of layers should be rounded up or down.

[0084] In an embodiment of the present invention, the number of segments after reduction is the product of the number of segments and the j-th preset segment adjustment coefficient, where j is 1 or 2, R1 is the first preset segment adjustment coefficient 0.8, and R2 is the second preset segment adjustment coefficient 0.5. It can be understood that the number of segments after reduction should be an integer, and the non-integer number of segments should be rounded off.

[0085] Specifically, the present invention determines the eligibility of the control method through the influence value, and adjusts the concrete pouring height according to the difference between the influence value and the preset influence value when it is unqualified, thereby improving the accuracy of the concrete pouring construction and the accuracy of the concrete pouring height control method during the construction process, thereby improving the efficiency of the concrete pouring height construction.

[0086] See also Figure 4 The flow chart for determining whether the concrete quality is within a reasonable range is shown below.

[0087] Specifically, under the condition that the control method of concrete pouring height is determined, the embodiment of the present invention determines whether the concrete quality is within a reasonable range by comparing the texture uniformity value of the concrete after pouring each layer or each section with the preset texture uniformity value of 0.89;

[0088] When the texture uniformity value is less than the preset texture uniformity value, it is determined that the quality of the concrete is not within a reasonable range;

[0089] When the texture uniformity value is greater than or equal to a preset texture uniformity value, it is determined that the quality of the concrete is within a reasonable range.

[0090] In the embodiment of the present invention, the preset texture uniformity value is 0.89. The preset texture uniformity value is obtained by taking the average of the texture uniformity values ​​of several concretes whose quality is within a reasonable range. However, the above value is not limited to this. Those skilled in the art can also adjust the value according to actual needs.

[0091] Specifically, the embodiment of the present invention calculates the texture uniformity value according to the following formula, setting:

[0092]

[0093] in, Indicates the texture uniformity value, is the standard deviation of ultrasonic wave velocity, is the average value of ultrasonic wave velocity, is the number of qualified test points, is the total number of test points, and the qualified test points are the test points whose ultrasonic wave velocity meets the standard, and the standard ultrasonic wave velocity that meets the standard is 3500m / s-4500m / s.

[0094] Specifically, under the condition that it is determined that the concrete quality is not within a reasonable range, the embodiment of the present invention determines the adjustment method of the single pouring height based on the comparison result of the ratio of the texture uniformity value to the preset texture uniformity value and the preset ratio of 0.35;

[0095] When the ratio is less than or equal to the preset ratio, it is determined to increase the single pouring height to a corresponding value using a first preset single pouring height adjustment coefficient of 1.3;

[0096] When the ratio is greater than the preset ratio, it is determined to increase the single pouring height to a corresponding value using a second preset single pouring height adjustment coefficient of 1.5;

[0097] The ratio is the ratio of the texture uniformity value to the preset texture uniformity value.

[0098] In the embodiment of the present invention, the preset ratio is 0.35, but the above value is not limited thereto, and those skilled in the art may also adjust the value according to actual needs.

[0099] In an embodiment of the present invention, the increased single pouring height is the product of the single pouring height and the mth preset single pouring height adjustment coefficient, where m is 1 or 2, U1 is the first preset single pouring height adjustment coefficient of 1.3, and U2 is the second preset single pouring height adjustment coefficient of 1.5.

[0100] Specifically, the present invention evaluates the quality of concrete by comparing the concrete texture uniformity with the preset texture uniformity. If the quality does not meet the standard, the single pouring height is adjusted according to the ratio of the texture uniformity to the preset value, thereby improving the concrete pouring quality, ensuring the stability and consistency of the concrete quality, and improving the construction quality of underwater bridge pile foundations.
