Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to a tunnel construction method for a data center. Background Art

[0002] Cavern-type data centers are a new type of infrastructure that utilizes caverns excavated from mountains or converted underground spaces to centrally deploy electronic information equipment. They are one of the three main types of data centers. Their core characteristic is that they leverage the protective and environmental stability of natural rock formations to provide a highly secure, low-energy operating environment for servers. Data center equipment is highly sensitive to ambient humidity. High humidity can cause condensation on equipment surfaces, leading to corrosion and short circuits, seriously impacting equipment lifespan and operational stability. Furthermore, high humidity reduces equipment heat dissipation efficiency, causing overheating and reduced operating efficiency, even leading to system crashes. Existing technologies implement ventilation in stages based on the construction steps of cavern clusters, achieving good ventilation results. However, cavern construction typically involves extensive civil engineering and equipment installation, which can lead to elevated humidity levels within the caverns. Traditional humidity monitoring methods are often unable to monitor humidity changes in real time, resulting in delayed detection of problems. Traditional methods also struggle to dynamically adjust humidity control parameters based on construction progress and environmental changes, resulting in poor adaptability.

[0003] Chinese patent application number: CN202410871370.6 discloses an underground cavern group structure and its construction ventilation method, wherein the cavern group body includes a number of cavern units, a first channel and a second channel; the number of cavern units are arranged into two rows of cavern groups with parallel arrangement directions; the first channel includes a first section with an extension direction parallel to the arrangement direction of the cavern group; the second channel includes a second section parallel to the first section, and in a top-down state, the first section and the second section are both located between the two rows of cavern groups, and the second section is buried shallower than the first section; the number of cavern units are each connected to the first section through a group of first branch channels, and each group of first branch channels is perpendicular to the first section; the number of cavern units are each connected to the second section through a group of second branch channels, and the number of second branch channels are all inclined to the same degree and connected to the second section; the underground cavern group structure construction ventilation method of the present invention implements ventilation in stages according to the forming steps of the cavern group, and has significant work efficiency.

[0004] However, the prior art still has the following problems:

[0005] Since cave construction usually involves a large amount of civil engineering and equipment installation, these processes may cause the humidity inside the cave to rise. Traditional humidity detection methods are usually unable to monitor humidity changes inside the cave in real time, resulting in untimely problem discovery. Traditional methods are difficult to dynamically adjust humidity control parameters according to construction progress and environmental changes, and have poor adaptability. Summary of the Invention

[0006] To this end, the present invention provides a cave construction method for a data center, which is used to overcome the problem in the prior art that cave construction usually involves a large amount of civil engineering and equipment installation, which may cause the humidity in the cave to rise. Traditional humidity detection methods are usually unable to monitor the humidity changes in the cave in real time, resulting in untimely problem discovery. Traditional methods are difficult to dynamically adjust humidity control parameters according to construction progress and environmental changes, and have poor adaptability.

[0007] To achieve the above objectives, the present invention provides a cavern construction method for a data center, comprising:

[0008] Step S1: Determine the construction area, construct the cavern according to the construction plan, divide the construction area in the cavern into several construction sub-areas, and periodically detect the humidity in each construction sub-area;

[0009] Step S2: Preliminarily analyzing whether the cavern construction is qualified based on the measured humidity in each construction area. If the preliminary judgment is that the cavern construction is unqualified, a secondary judgment is made based on historical humidity data to determine whether the cavern construction is qualified, or the reason for the unqualified cavern construction is analyzed based on the humidity changes.

[0010] Step S3: Based on the analyzed reasons for the unqualified construction of the cave, the corresponding parameters are adjusted to the corresponding values, and the construction is carried out according to the adjusted parameters. The parameters include: the first preset current average humidity, the power of the fan, the number of branch ducts, and the vertical distance between the humidity sensors.

[0011] Furthermore, in step S2, a preliminary analysis is performed to determine whether the cavern construction is qualified based on the measured humidity in each construction area, including:

[0012] Determine the humidity of each construction area at the current detection time node,

[0013] Solve the average humidity of each construction area to get the current average humidity.

[0014] If the current average humidity is less than or equal to the first preset current average humidity, the construction of the cavern is determined to be qualified, and the construction is carried out according to the initial construction parameters;

[0015] If the current average humidity is greater than the first preset current average humidity and less than or equal to the second preset current average humidity, a preliminary determination is made that the construction of the cavern is unqualified, and a secondary determination is made as to whether the construction of the cavern is qualified based on historical humidity data;

[0016] If the current average humidity is greater than the second preset current average humidity, it is determined that the construction of the cave is unqualified, and the reasons for the unqualified construction of the cave are analyzed based on the change in humidity.

[0017] Furthermore, the secondary determination of whether the cavern construction is qualified based on the historical humidity data includes:

[0018] Obtain the humidity data of each construction sub-area in the historical data,

[0019] Calculate the average humidity of each construction sub-area corresponding to a single time node,

[0020] Calculate the variance of each mean humidity,

[0021] If the variance is less than or equal to the preset variance, it is determined that the rock formation environment does not meet expectations;

[0022] If the variance is greater than the preset variance, it is determined that the construction of the cave is unqualified, and the reasons for the unqualified construction of the cave are analyzed based on the change of humidity.

[0023] Furthermore, when it is determined that the rock formation environment is not consistent with expectations, the first preset current average humidity is corrected based on the volume of the cavern, wherein the increase in the first preset current average humidity is negatively correlated with the volume of the cavern.

[0024] Furthermore, the analysis of reasons for unqualified cavern construction based on humidity changes includes:

[0025] Determine the historical humidity data for each construction sub-area,

[0026] Calculate the average humidity of each construction sub-area corresponding to a single depth in the cave to obtain the axial humidity.

[0027] Draw the depth-axial humidity curve and calculate the integral of the curve.

[0028] If the integral is less than or equal to the preset integral, the cause of the failure of the tunnel construction is determined to be the failure of the fan operation;

[0029] If the integral is greater than the preset integral, the reason for the unqualified construction of the cavern is determined based on the secondary analysis of the time domain discreteness of the axial humidity.

[0030] Furthermore, under the condition that the fan operation is determined to be unqualified, the difference between the current average humidity and the second preset current average humidity is calculated to obtain the average humidity deviation, and the power of each fan is adjusted based on the average humidity deviation, wherein the increase in power is positively correlated with the average humidity deviation.

[0031] Furthermore, when determining the power of each fan after adjustment, the power to be adjusted of each fan is obtained, and whether to add a branch duct is analyzed based on the power to be adjusted of a single fan.

[0032] If the power to be adjusted is less than or equal to the preset power threshold, it is determined that no branch duct will be added, and the power of the fan is adjusted to the power to be adjusted;

[0033] If the power to be adjusted is greater than the preset power threshold, it is determined to add branch air ducts and adjust the power of the fan to the preset power threshold, wherein the increase in the number of branch air ducts is positively correlated with the power to be adjusted.

[0034] Furthermore, the secondary analysis of the time-domain discreteness based on axial humidity for the reasons for the unqualified construction of the cavern includes:

[0035] Calculate the variance of each axial humidity to obtain the time domain discreteness,

[0036] If the time domain dispersion is less than or equal to the preset time domain dispersion, it is determined that the cause of the unqualified construction of the tunnel is the unqualified operation of the fan;

[0037] If the time domain discreteness is greater than the preset time domain discreteness, it is determined that the reason for the unqualified construction of the tunnel is that the position of the sensor is unqualified.

[0038] Furthermore, under the condition that the position of the sensor is determined to be unqualified, the average value of the slope of the curve at each time node in the depth-axial humidity curve is calculated to obtain the average slope, and the vertical distance spacing of each humidity sensor is adjusted based on the average slope, wherein the shortening amplitude of the spacing is positively correlated with the average slope.

[0039] Compared with the prior art, the beneficial effect of the present invention lies in that the humidity in the cave is periodically detected during the construction process to determine the ventilation condition of the cave according to the humidity of the cave, the cave is divided into several construction sub-areas, the humidity of each construction sub-area is detected separately, and whether the construction process of the cave is qualified is analyzed based on the measured humidity. When the humidity is between the first preset current average humidity and the second preset current average humidity, a second judgment is made on whether the construction of the cave is qualified based on historical humidity data, thereby improving the control accuracy of the ventilation condition of the cave during the construction process, and further improving the analysis accuracy of the ventilation condition of the cave, making it convenient to adjust the corresponding parameters in time according to the analysis results, thereby ensuring the ventilation effect and improving the construction efficiency of the cave.

[0040] Furthermore, the present invention takes into account that the equipment in the data center is very sensitive to environmental humidity. A high humidity environment will cause condensation on the surface of the equipment, which will in turn cause problems such as corrosion and short circuits, seriously affecting the service life and operational stability of the equipment. The present invention periodically detects the humidity in the cave and makes construction adjustments based on the humidity data, which can effectively prevent equipment corrosion and failures caused by excessive humidity.

[0041] Furthermore, the present invention takes into account that the long-term stable operation of the data center requires good environmental conditions. A high humidity environment may not only cause equipment failures, but may also affect the long-term performance and life of the equipment. By analyzing humidity data and adjusting construction parameters in a timely manner, it can be ensured that the humidity in the cave is always maintained within the design range, providing protection for the long-term stable operation of the data center.

[0042] Furthermore, the present invention sets a first preset current average humidity and a second preset current average humidity, and makes a preliminary judgment based on the current average humidity, thereby being able to scientifically and rationally evaluate construction quality, timely discover and resolve potential problems, optimize construction parameters, improve construction efficiency, reduce construction costs, enhance the reliability of the construction process, support continuous improvement, and promote technical standardization.

[0043] Furthermore, in the present invention, a secondary judgment is made on whether the construction process of the cavern is qualified based on the degree of dispersion of the humidity at each time node during the construction process of the cavern. The larger the variance, the greater the change in humidity in the cavern over time, and the humidity does not meet expectations. Therefore, it is judged that the construction of the cavern is unqualified, and the reasons for the unqualified construction are analyzed, thereby improving the control accuracy of the ventilation conditions in the cavern.

[0058] The present invention takes into account that the equipment in the data center is very sensitive to environmental humidity. A high humidity environment will cause condensation on the surface of the equipment, which will in turn cause problems such as corrosion and short circuits, seriously affecting the service life and operational stability of the equipment. The present invention periodically detects the humidity in the cave and makes construction adjustments based on the humidity data, which can effectively prevent equipment corrosion and failures caused by excessive humidity.

[0059] See also Figure 2 As shown, it is a flowchart for preliminary analysis of whether the construction of the tunnel is qualified.

[0060] Specifically, in step S2, a preliminary analysis is conducted to determine whether the cavern construction is qualified based on the measured humidity in each construction area, including:

[0061] Determine the humidity of each construction area at the current detection time node,

[0062] Solve the average humidity of each construction area to get the current average humidity.

[0063] If the current average humidity is less than or equal to the first preset current average humidity, the construction of the cavern is determined to be qualified, and the construction is carried out according to the initial construction parameters;

[0064] If the current average humidity is greater than the first preset current average humidity and less than or equal to the second preset current average humidity, a preliminary determination is made that the construction of the cavern is unqualified, and a secondary determination is made as to whether the construction of the cavern is qualified based on historical humidity data;

[0065] If the current average humidity is greater than the second preset current average humidity, it is determined that the construction of the cave is unqualified, and the reasons for the unqualified construction of the cave are analyzed based on the change in humidity.

[0066] Specifically, in this embodiment, the first preset current average humidity and the second preset current average humidity are obtained in advance. Humidity data during the construction process of several qualified tunnels are obtained to solve the average value of the humidity. The first preset current average humidity is 0.95~1.05 times the average value, and the second preset current average humidity is 1.15~1.2 times the average value.

Therefore, it is judged that the construction of the cavern is unqualified, and the reasons for the unqualified construction are analyzed, thereby improving the control accuracy of the ventilation conditions in the cavern.
