Soft roadbed is made of polypropylene fiber and other materials as raw materials, and is made through special processing and treatment. It has good drainage and permeability, and can effectively improve the bearing capacity and stability of the highway. Soft roadbed is widely used in the construction of roads and highways and has become an important material. Soft roadbed has many unique characteristics. First, soft roadbed has excellent geotechnical properties, can effectively resist the influence of different landforms, different climates and different vehicles, and has good adaptability. Secondly, soft roadbed has good drainage and permeability, which can effectively reduce the amount of water accumulation on the highway, reduce soil erosion, and prevent road collapse and disintegration. In addition, soft roadbed can also effectively reduce the time and cost of highway construction and improve the efficiency and quality of highway construction.

[0050] Furthermore, when determining the secondary initial water displacement in S500:

[0051] When the historical data contains data identical to the drainage influencing factor, drainage is performed with the recorded secondary initial drainage volume;

[0052] When there is no data identical to the drainage influencing factor in the historical data, the drainage influencing factor is stored and the secondary initial drainage volume is determined.

[0053] Furthermore, when determining the secondary initial water discharge volume according to the comparison result in S500:

[0060] When the second sludge average water content is less than the sludge water content threshold, the i-th preset secondary initial drainage volume Wi is used as the secondary drainage volume, and the secondary drainage volume is stored;

[0061] When the second sludge average water content is greater than or equal to the sludge water content threshold, it is determined that the i-th preset secondary initial drainage volume Wi is adjusted to obtain the secondary drainage volume.

[0072] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] Example:

[0074] See also Figure 1 In an embodiment of the present invention, a sludge treatment method for improving soft roadbed resources comprises the following steps:

[0075] S100: collecting the moisture content of the sludge before improvement in a preset area, and establishing a first sludge moisture content data set according to the moisture content of the sludge before improvement;

[0076] S200: obtaining a first sludge average moisture content according to a first sludge moisture content data set, comparing the first sludge average moisture content with a preset sludge moisture content threshold, and judging whether to improve the sludge according to the comparison result; when judging that the sludge is to be improved, determining a drainage volume according to the moisture content difference;

[0077] S300: draining and improving the sludge in the preset area according to the primary drainage volume, then collecting the water content of the improved sludge in the preset area, and establishing a second sludge water content data set according to the water content of the improved sludge;

[0078] S400: comparing the water content data of each improved sludge in the second sludge water content data set with the sludge water content threshold, and judging whether the drainage device is blocked according to the comparison result; when it is determined that the drainage device is blocked, controlling the high-pressure water gun to dredge the drainage device;

[0079] S500: After the drainage device is dredged, the shear strength in the preset area is collected, the drainage influence factor is calculated according to the second sludge moisture data set and the shear strength, the drainage influence factor is compared with the historical data, and the secondary initial drainage volume is determined according to the comparison result;

[0080] S600: when the drainage influencing factor is different from the drainage influencing factor in the historical data, the location to be drained is collected, the first silt moisture content data set of the location to be drained is compared with the second silt moisture content data set, the secondary initial drainage is determined according to the comparison result, and the secondary initial drainage is performed; the third silt moisture content data of the location to be drained after the secondary initial drainage is completed is collected, the location data to be drained in the second silt moisture content data set is replaced with the third silt moisture content data, the second average silt moisture content is calculated, the second average silt moisture content is compared with the silt moisture content threshold, and whether the secondary initial drainage is adjusted is determined according to the comparison result, and the secondary drainage is determined;

[0081] S700: The drainage influencing factor and the secondary drainage volume are stored.

[0082] By collecting the moisture content of the sludge before improvement in the preset area and establishing the first sludge moisture content data set based on the moisture content of the sludge before improvement, the moisture content of the entire preset area can be monitored and evaluated in detail; by comparing the average moisture content of the first sludge with the preset sludge moisture content threshold, it can be quickly determined whether the sludge needs to be improved, thereby ensuring the stability and bearing capacity of the soft roadbed; by collecting the moisture content of the sludge after improvement in the preset area and establishing the second sludge moisture content data set based on the moisture content of the sludge after improvement, the effect of sludge improvement can be monitored in real time to ensure the effective implementation of drainage and improvement measures; during the drainage process, based on the comparison results of the data in the second sludge moisture content data set with the sludge moisture content threshold, it can be determined whether the drainage device is blocked. Once blockage is found, the high-pressure water gun will be immediately started to clear it to ensure the continuity and efficiency of the drainage process.

[0083] After completing the initial drainage and sludge improvement, by collecting the shear strength in the preset area and combining it with the second sludge moisture data set, the drainage influence factor can be calculated, which can further and more accurately evaluate the drainage effect and the degree of sludge improvement. When the drainage influence factor is different from the historical data, more detailed investigation and adjustment are required; by collecting the location to be drained and comparing the first sludge moisture data set with the second sludge moisture data set, the secondary initial drainage volume is further determined, and the secondary initial drainage is carried out, which not only improves the drainage efficiency, but also ensures the accuracy and pertinence of the drainage process; after completing the secondary initial drainage, the third sludge moisture data of the location to be drained will be collected, and the second sludge moisture data set will be updated. By calculating the new second average sludge moisture content and comparing it with the sludge moisture threshold, it is further determined whether the secondary initial drainage volume needs to be adjusted to determine the final secondary drainage volume; finally, the drainage influence factor and the secondary drainage volume are stored, which not only provides valuable data support for subsequent sludge treatment, but also provides an important reference basis for technical improvement and optimization.

[0084] Among them, when determining whether to improve the sludge in S200:

[0085] When the average water content of the first sludge is less than the sludge water content threshold, it is determined that the sludge should be improved;

[0086] When the first average sludge water content is greater than or equal to the sludge water content threshold, it is determined that the sludge is to be improved, and the water content difference is calculated according to the first average sludge water content and the sludge water content threshold.

[0087] When the average moisture content of the first silt is less than the silt moisture content threshold, it means that the moisture content of the silt is low and may not meet the requirements of the soft roadbed for bearing capacity and stability. Therefore, it is directly determined that the silt needs to be improved; when the average moisture content of the first silt is greater than or equal to the silt moisture content threshold, the moisture content of the silt is too high, which will affect the performance of the soft roadbed. It is necessary to determine that the silt needs to be improved, and the moisture content difference needs to be further calculated to determine the amount of water that needs to be discharged, so as to more accurately control the moisture content of the silt.

[0088] Among them, when determining the primary discharge volume in S200:

[0089] Presetting a first preset moisture content difference and a second preset moisture content difference, the first preset moisture content difference is smaller than the second preset moisture content difference, comparing the moisture content difference with the first preset moisture content difference and the second preset moisture content difference, and determining a drainage volume according to the comparison result;

[0090] When the moisture content difference is less than or equal to the first preset moisture content difference, determining the primary drainage volume as the first preset primary drainage volume;

[0091] When the moisture content difference is greater than the first preset moisture content difference and less than or equal to the second preset moisture content difference, determining the first drainage volume to be the second preset first drainage volume;

[0092] When the moisture content difference is greater than the second preset moisture content difference, determining the primary drainage volume to be the third preset primary drainage volume;

[0093] Among them, the first preset primary displacement is smaller than the second preset primary displacement, and the second preset primary displacement is smaller than the third preset primary displacement.

[0094] By setting different preset moisture content differences and the corresponding primary drainage volumes, the drainage process can be controlled more accurately to ensure that the silt moisture content can quickly and accurately reach the preset silt moisture content threshold, thereby improving the bearing capacity and stability of the soft roadbed.

[0095] Among them, when determining whether the drainage device is blocked in S400:

[0096] When the water content data of each improved sludge in the second sludge water content data set are all less than or equal to the water content threshold, it is determined that the drainage device is not blocked;

[0097] When the moisture content data of the improved sludge in the second sludge moisture content data set is greater than the moisture content threshold, it is determined that the drainage device is blocked and the number of high moisture content data is recorded.

[0098] During the drainage process, real-time monitoring of whether the drainage device is blocked is the key to ensuring the smooth progress of drainage work. Once it is determined that the drainage device is blocked, the system will immediately initiate emergency measures, such as clearing it with a high-pressure water gun, to ensure the continuity and efficiency of the drainage process; recording the number of high water content data helps us more accurately judge the severity of the blockage and provide data support for subsequent repairs and maintenance.

[0099] Among them, when it is determined that the drainage device is blocked:

[0100] The proportion of high water content data is obtained according to the number of high water content data, and the proportion of high water content data is the ratio of the number of high water content data to the total number of data in the second sludge water content data set;

[0101] Determine the dredging mode of the high-pressure water gun based on the proportion of high-water content data;

[0102] A high water content data ratio threshold is preset, and the high water content data ratio is compared with the high water content data ratio threshold;

[0103] When the proportion of high water content data is less than the high water content data proportion threshold, a low-pressure, low-speed dredging mode is adopted;

[0104] When the proportion of high water content data is greater than or equal to the high water content data proportion threshold, a high-pressure and high-speed dredging mode is adopted.

[0105] When it is determined that the drainage device is blocked and it is necessary to start a high-pressure water gun for dredging, it is necessary to select the appropriate dredging mode based on the proportion of high water content data. The selection of this mode is based on an accurate assessment of the degree of blockage to ensure that the dredging work is both efficient and safe. When the proportion of high water content data is small, that is, the degree of blockage is light, only a low-pressure, low-speed dredging mode is needed to reduce damage to the drainage device and prevent aggravation of blockage due to improper operation; when the proportion of high water content data reaches or exceeds the preset threshold, that is, the degree of blockage is heavy, a high-pressure, high-speed dredging mode is needed to quickly and effectively remove the blockage and restore the normal operation of the drainage device.

[0106] Among them, when calculating the drainage impact factor in S500:

[0107] A coordinate system is established with the center point of the drainage device as the origin, and the position (ai, bi) of each data in the second sludge moisture content data set is recorded. The moisture content of each improved sludge in the second sludge moisture content data set is recorded as Si, and the origin is recorded as (a0, b0);

[0108] Calculate the distance from each data in the second sludge moisture content data set to the origin;

[0109] ;

[0110] Where Ji represents the distance from the i-th data in the second silt moisture content data set to the origin;

[0111] Calculate the weight of each data in the second sludge moisture content data set:

[0112] ;

[0113] Among them, Wi represents the weight of the i-th data in the second sludge moisture content data set, and z is a constant;

[0114] Normalize Wi to get Wi':

[0115] ;

[0116] Among them, Wi' is the weight of each data in the normalized second sludge moisture content data set, k is

[0117] The total number of data in the second silt moisture content data set, Wk represents the weight of the kth data in the second silt moisture content data set;

[0118] Calculate the moisture content of the overall improved sludge:

[0119] ;

[0120] Calculate drainage impact factor:

[0121] ;

[0122] Among them, P represents the drainage influence factor, M represents the shear strength, α and β are weights, and α+β=1.

[0123] When evaluating the effect of drainage devices on sludge improvement, the calculation of drainage influence factors is a crucial link. Through a comprehensive analysis of the water content data and shear strength of the improved sludge, the contribution of the drainage process to the improvement of soft roadbed can be more accurately evaluated; by setting reasonable weights α and β, the influence of water content data and shear strength in the calculation of drainage influence factors can be adjusted according to actual needs, so as to obtain an evaluation result that is more in line with the actual situation.

[0124] Among them, when determining the secondary initial displacement in S500:

[0125] When the historical data contains the same data as the drainage influencing factor, drainage is carried out with the recorded secondary initial drainage volume;

[0126] When there is no data identical to the drainage influencing factor in the historical data, the drainage influencing factor is stored and the secondary initial drainage volume is determined.

[0127] In the drainage process, the use of historical data is the key to improving drainage efficiency and ensuring drainage effects. By comparing the currently calculated drainage influence factor with historical data, the appropriate secondary initial drainage volume can be quickly determined, thereby avoiding the waste of time and resources caused by repeated experiments. When the historical data contains the same data as the current drainage influence factor, the recorded secondary initial drainage volume can be directly used to achieve fast and accurate drainage operations; when the same data does not exist in the historical data, the current drainage influence factor is stored, and based on previous drainage experience and actual conditions, the appropriate secondary initial drainage volume is determined to provide a reference for subsequent drainage work.

[0128] Among them, when determining the secondary initial water discharge volume according to the comparison result in S500:

[0129] According to the water content of the sludge before improvement and the water content of the sludge after improvement, a water content difference after drainage is obtained, and the water content difference after drainage is compared with a first preset water content difference after drainage and a second preset water content difference after drainage, respectively. The first preset water content difference after drainage is less than the second preset water content difference after drainage, and the secondary initial drainage is determined according to the comparison result;

[0130] When the water content difference after drainage is less than or equal to the first preset water content difference after drainage, the secondary initial drainage volume is determined to be the first preset secondary initial drainage volume W1;

[0131] When the water content difference after drainage is greater than the first preset water content difference after drainage and less than or equal to the second preset water content difference after drainage, the secondary initial drainage volume is determined to be the second preset secondary initial drainage volume W2;

[0132] When the water content difference after drainage is greater than the second preset water content difference after drainage, the secondary initial drainage volume is determined to be the third preset secondary initial drainage volume W3;

[0133] The first preset secondary initial displacement W1 is smaller than the second preset secondary initial displacement W2, and the second preset secondary initial displacement W2 is smaller than the third preset secondary initial displacement W3.

[0134] When determining the secondary initial drainage volume, an accurate assessment of the difference in moisture content after drainage is crucial. This assessment method not only takes into account the changes in sludge moisture content before and after drainage, but also refines the adjustment range of the drainage volume by setting different preset differences in moisture content after drainage, so as to more accurately meet the drainage needs. When the difference in moisture content after drainage is small, it indicates that the drainage effect is good and the moisture content of the sludge has been significantly reduced. At this time, a smaller secondary initial drainage volume can be used to avoid unnecessary damage to the drainage device and soft roadbed caused by excessive drainage; when the difference in moisture content after drainage is large, the secondary initial drainage volume needs to be increased to ensure that the drainage work can thoroughly and effectively remove the excess water in the sludge and restore the stability and bearing capacity of the soft roadbed.

[0135] In the drainage process, in order to ensure the drainage effect and avoid damage to the drainage device and soft roadbed, the drainage speed needs to be precisely controlled. Furthermore, when the difference in water content after drainage is large, in addition to increasing the secondary initial drainage volume, the drainage speed needs to be appropriately increased to speed up the drainage process; when the difference in water content after drainage is small, the drainage speed can be appropriately reduced to avoid excessive drainage causing adverse effects on the soft roadbed. This comprehensive control of drainage speed and drainage volume can achieve refined management of the drainage process and ensure that drainage work is both efficient and safe.

[0136] Among them, when it is determined that the secondary initial displacement is the i-th preset secondary initial displacement Wi, it is determined whether to adjust the secondary initial displacement according to the comparison result, and when the secondary displacement is determined:

[0137] When the second average sludge water content is less than the sludge water content threshold, the i-th preset secondary initial drainage volume Wi is used as the secondary drainage volume, and the secondary drainage volume is stored;

[0138] When the second average sludge water content is greater than or equal to the sludge water content threshold, it is determined that the i-th preset secondary initial drainage volume Wi is adjusted to obtain the secondary drainage volume.

[0139] During the drainage process, real-time monitoring and adjustment of sludge moisture content is the key to ensuring drainage effect. When the second average sludge moisture content is less than the sludge moisture content threshold, it means that the sludge moisture content has been significantly reduced and the expected drainage effect has been achieved. At this time, the i-th preset secondary initial drainage volume Wi can be directly used as the secondary drainage volume and stored to provide a reference for subsequent drainage work; and when the second average sludge moisture content is greater than or equal to the sludge moisture content threshold, it means that the sludge moisture content is still high and further drainage is required. In this case, the system will adjust the i-th preset secondary initial drainage volume Wi according to the actual drainage situation and the changing trend of the sludge moisture content to obtain a more appropriate secondary drainage volume to ensure the continuity and effectiveness of the drainage work. This drainage adjustment mechanism based on real-time feedback of sludge moisture content can not only improve drainage efficiency, but also ensure the safety and reliability of drainage work.

[0140] Among them, when adjusting the secondary initial displacement:

[0141] Obtaining a discharge difference value according to the second average sludge water content and the sludge water content threshold;

[0142] According to the displacement difference, an adjustment coefficient B is determined to adjust the i-th preset secondary initial displacement Wi to obtain an adjusted displacement;

[0143] The adjusted displacement is used as the secondary displacement, and the secondary displacement is stored;

[0144] The adjustment coefficient B is proportional to the displacement difference.

[0145] In the process of adjusting the drainage volume, the adjustment coefficient B is introduced to more accurately control the change of drainage volume and ensure the accuracy and stability of drainage work. By calculating the drainage volume difference between the second average sludge moisture content and the sludge moisture content threshold, the gap between the current sludge moisture content and the expected moisture content can be directly reflected; based on this drainage volume difference, a corresponding adjustment coefficient B can be determined to fine-tune the initial secondary initial drainage volume set initially; the proportional relationship between the adjustment coefficient B and the drainage volume difference means that when the drainage volume difference is large, the adjustment coefficient B will also increase accordingly, thereby increasing the drainage volume to reduce the sludge moisture content more quickly; conversely, when the drainage volume difference is small, the adjustment coefficient B will decrease, reducing the drainage volume and avoiding excessive drainage. This dynamic adjustment mechanism ensures the flexibility and adaptability of drainage work, and can automatically adjust the drainage volume according to the changes in sludge moisture content under different circumstances to achieve the optimization of drainage effect.
