They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

[0056] Example:

[0057] like Figure 1-Figure 5 As shown, a sample material compaction quality assessment device includes a weighing module 1, a drying module 2, a control module 3 and a report generating module 4, wherein the control module 3 is electrically connected to the weighing module 1, the drying module 2 and the report generating module 4 respectively;

[0058] The weighing module 1 is used to measure the mass of the wet material and the dry material;

[0059] The drying module 2 is used to dry the wet material into dry material;

[0060] The control module 3 is used to calculate the parameters of the sample material;

[0061] The report generation module 4 is used to generate a material compaction quality assessment report;

[0062] Accordingly, the control module 3 obtains the parameters of the sample material based on the parameters of the weighing module 1 and the drying module 2 ; the report generation module 4 obtains the material compaction quality assessment report based on the sample material parameters calculated by the control module 3 .

[0063] In the sample material compaction quality assessment device, wet material refers to sample material obtained from the location to be tested, such as gravel soil excavated from an earth-rock dam, the wet material is unprocessed and contains a certain amount of moisture, and the wet material is dried by the drying module 2 to obtain dry material. It is easy to understand that the sample material includes but is not limited to gravel soil of an earth-rock dam, that is, the sample material compaction quality assessment device can be used for any suitable material.

[0064] For the staff, after obtaining a certain amount of wet material, the sample material compaction quality assessment device can be used to perform the assessment operation. Specifically, the wet material is weighed by the weighing module 1, and the dry material is weighed by the weighing module 1 after drying by the drying module 2. The above measurement data will be transmitted to the control module 3, and the staff will input other relevant data. The control module 3 will calculate through any prefabricated appropriate existing model to obtain the point counting data. The report generation module 4 integrates the measurement data, input data and point counting data, and generates a material compaction quality assessment report through any prefabricated appropriate existing model.

[0065] Therefore, the multi-dimensional and comprehensive feedback on the compaction performance of the sample materials provides evaluation and feedback on the material quality in the test area. When used for the evaluation of buildings, it effectively feeds back the construction quality, helping construction managers to quickly adjust the construction process and improve construction efficiency and quality.

[0066] Furthermore, the staff only needs to perform two measurements, one drying and input some data, which effectively simplifies the operation process, helps to improve the detection speed, reduce the detection time, and realize rapid detection. Through the cooperation between the control module 3 and the report generation module 4, intelligent evaluation is realized, the workload of the staff is reduced, and the material compaction quality assessment report is more authentic and reliable.

[0067] In one possible implementation, the weighing module 1 includes a weighing platform 11, a shock-absorbing bracket 12 and a mass sensor 13. The weighing platform 11 has a weighing area for placing sample materials. The shock-absorbing bracket 12 is arranged on the weighing platform 11. The mass sensor 13 is connected to the weighing area of ​​the weighing platform 11 through the shock-absorbing bracket 12.

[0068] Based on the above design, the weighing platform 11 can be any suitable existing weighing equipment, and the selection range is wide. It is easy to understand that the weighing platform 11 is preferably made of waterproof and corrosion-resistant materials, which are moisture-resistant and easy to clean, and can resist corrosion from chemical substances. At least the surface of the weighing area is smooth to prevent moisture retention and accumulation when weighing wet materials.

[0069] The shock-absorbing bracket 12 reduces the influence of vibration on the symmetry by using elastic materials. The mass sensor 13 is preferably a high-precision model to accurately measure the mass of the sample material.

[0070] During operation, the wet material is first weighed by the weighing module 1 , and after the wet material is dried to obtain the dry material, the dry material is weighed by the weighing module 1 again.

[0071] In a possible implementation, the drying module 2 is placed on the weighing area of ​​the weighing platform 11 , or the drying module 2 replaces the weighing area of ​​the weighing module 1 .

[0072] Based on the above design, the weight of the drying module 2 is removed by de-grossing to ensure the accuracy of the weighing result. And because the drying module 2 and the weighing module 1 are designed as an integrated whole, when working, the staff only needs to place the sample material into the drying module 2. Compared with the separate design of the drying module 2 and the weighing module 1, the staff does not need to transfer the sample material multiple times, which helps to simplify the operation process.

[0073] In a possible implementation, the drying module 2 includes a box 21, a temperature controller 22, a temperature sensor 23 and a timer 24;

[0074] The box body 21 is provided with an air inlet for introducing air and an air outlet for discharging moisture;

[0075] The thermostat 22, temperature sensor 23 and timer 24 are all arranged on the box 21, and the controller is electrically connected to the temperature sensor 23 and the timer 24. The thermostat 22 is used to heat and maintain the set drying temperature, the temperature sensor 23 is used to measure the real-time temperature of the box 21, and the timer 24 is used to control the drying time.

[0076] Based on the above design, the box 21 is the main part of the drying module 2, which has good sealing to prevent heat loss, thereby improving the drying efficiency. At the same time, in order to ensure the drying effect, the box 21 is provided with an air inlet for introducing air and an air outlet for discharging moisture.

[0077] The thermostat 22 is used for heating and heat preservation to complete the drying operation. The temperature sensor 23 is used to measure the temperature of the box 21, and it is used in conjunction with the thermostat 22 to improve the drying efficiency. The timer 24 is used to set the drying time. It is easy to understand that by combining the respective parameters of the thermostat 22, the temperature sensor 23 and the timer 24, a variety of preset drying programs are formed for different types of materials, and the appropriate drying temperature and time are automatically set, which not only has better adaptability, but also can reduce manual operations and improve drying efficiency. As a result, the drying module 2 realizes a more efficient and intelligent wet material drying process, ensures the quality of the dry material, and reduces manual intervention.

[0078] During operation, according to the properties of the wet material, the staff sets the appropriate drying temperature and drying time, or selects an appropriate drying program, and then starts the drying module 2. The thermostat 22 will quickly heat the air in the box 21, introduce fresh air through the air inlet, maintain heat circulation, and stabilize the temperature. The temperature sensor 23 is linked with the thermostat 22 to monitor the internal temperature of the box 21 in real time to ensure that the temperature is maintained within the set range during the entire drying process.

[0079] The wet material is evenly heated in the box 21, and the water evaporates gradually. The timer 24 continuously monitors the drying process within the set time. When the drying time reaches the preset value, the timer 24 automatically cuts off the power supply of the temperature control device, stops heating, and completes the drying process. At this time, the box 21 can be opened to take out the dried dry material.

[0080] It is easy to understand that the temperature controller 22, the temperature sensor 23 and the timer 24 can be selected from any suitable existing models, respectively, with a wide range of choices and good practicality.

[0081] In a possible implementation, the control module 3 includes a first processor 31, a first memory 32, a first display 33 and a first input device 34;

[0082] The first processor 31 is electrically connected to the weighing module 1, the drying module 2, the report generating module 4, the first memory 32, the first display 33 and the first input device 34 respectively;

[0083] The first memory 32 is used to store data and calculation results, the first display 33 is used to display the operation interface, parameters and calculation results, and the first input device 34 is used to input parameters.

[0084] Based on the above design, the first processor 31 is the core of the control module 3, which is used to receive data from the weighing module 1 and the drying module 2, and perform real-time calculation and control. The first memory 32 is used to store relevant parameters, data and calculation results. The first display 33 is used to display the operation interface, input parameters and calculation results in real time. The first input device 34 is used to obtain user input, such as the user's settings for drying temperature and time, and other calculation parameters that need to be input.

[0085] Specifically, the parameters calculated by the control module 3 include the moisture content ω and the dry density ρ d ;

[0086] The moisture content ω is calculated by the following formula:

[0087]

[0088] Among them, m w is the mass of wet material obtained based on weighing module 1, m dis the mass of dry material obtained based on weighing module 1;

[0089] Dry density d Calculated by the following formula:

[0090]

[0091] Among them, m d is the mass of dry material obtained based on the weighing module 1, and V is the volume of the sample material.

[0092] Based on the above design, the volume V of the sample material can be obtained by any suitable existing method such as intuitive measurement method, drainage method, etc.

[0093] Control module 3 calculates the moisture content ω and dry density ρ d The data is calculated in real time and displayed on the first display 33, so that the staff can quickly obtain the test results. At the same time, the calculation results are stored in the first memory 32 for subsequent data analysis and report generation.

[0094] In a possible implementation, the report generation module 4 includes a second processor 41, a second memory 42, a second display 43, a second input device 44 and an output device 45;

[0095] The second processor 41 is electrically connected to the control module 3, the second memory 42, the second display 43, the second input device 44 and the output device 45;

[0096] The second memory 42 is used to store data and calculation results, the second display 43 is used to display the operation interface, parameters and calculation results, the second input device 44 is used to input parameters, and the output device 45 is used to generate electronic or paper reports.

[0097] Based on the above design, preferably, the second processor 41, the second memory 42, the second display 43, and the second input device 44 can be shared with the control module 3, that is, the first processor 31, the first memory 32, the first display 33, and the first input device 34 in the control module 3 and the second processor 41, the second memory 42, the second display 43, and the second input device 44 in the report generation module 4 use the same set of equipment to reduce the number of equipment and reduce economic costs. Alternatively, it is easy to understand that the control module 3 and the report generation module 4 are respectively constructed as independently configured components.

[0098] The output device 45 is used to generate electronic or paper reports, and provides multiple report format options, with a wide range of choices and better flexibility to meet different needs.

[0099] Specifically, based on the moisture content ω and dry density ρ of the sample material d, particle gradation P and compaction degree C, as well as relevant earth-rock dam information and quality control standard values, the report generation module 4 generates a material compaction quality assessment report; wherein the quality control standard value includes the moisture content standard value ω s , standard value of dry density ρ ds , particle size distribution standard value P s And the compaction standard value C s .

[0100] In addition, the material compaction quality assessment report also includes the sample material compaction quality assessment value Q:

[0101] Q=W ω ×Δω+W ρd ×Δρ d +W P ×ΔP+W c ×ΔC

[0102] Among them, W ω , W ρd , W P , W c are respectively the moisture content ω and dry density ρ of the sample material d , particle size distribution P, and compaction degree C are input by the user or determined based on earth-rock dam information; Δω, Δρ d , ΔP, ΔC are the moisture content ω and dry density ρ of the sample material respectively d , particle size distribution P, compaction degree C and moisture content standard value ω s , standard value of dry density ρ ds , particle size distribution standard value P s , compaction standard value C s The relative error of .

[0103] Based on the above design scheme, taking the gravel soil of the earth-rock dam as an example, the particle gradation P can be processed based on the captured dam material image, and any suitable existing image segmentation technology can be used to calculate the particle size of the segmented single particle image, thereby obtaining the overall particle gradation information of the earth-rock dam.

[0104] The compaction degree C can be obtained by collecting the test pit point cloud data through three-dimensional laser equipment, and obtaining the test pit point cloud with qualified quality through any appropriate existing test pit point cloud data processing, including denoising, simplification, segmentation and other steps, and constructing a calculation method for estimating the test pit volume based on the test pit point cloud data, so as to obtain the overall compaction degree of the earth-rock dam.

[0105] The material compaction quality assessment report includes not only the moisture content ω, dry density ρ d, particle size distribution P, compaction degree C and other original test data, and also compared the quality control standards of earth-rock dams, providing evaluation and feedback on the construction quality in the test area. It can provide instant feedback on the quality status of the construction site, which helps construction managers to quickly adjust the construction process and improve construction efficiency and quality.

[0106] This embodiment introduces an evaluation method based on the sample material compaction quality evaluation device, and the evaluation method includes the following steps:

[0107] S100: Weighing module 1 weighs the wet material and records the wet material mass m w ;

[0108] S200: Drying the wet material through the drying module 2 to obtain dry material;

[0109] S300: Weighing module 1 weighs the dry material and records the mass of the dry material m d ;

[0110] S400: Based on wet material mass m w and dry material mass m d , obtain the moisture content ω of the sample material;

[0111] S500: Based on the dry mass of the sample material m d and volume V, to obtain the dry density ρ of the sample material d ;

[0112] S600: Based on the moisture content ω and dry density ρ of the sample material d , particle gradation P and compaction degree C, as well as related earth-rock dam information and quality control standard values, the report generation module generates a material compaction quality assessment report, which also includes the sample material compaction quality assessment value Q, and Q = W ω ×Δω+W ρd ×Δρ d +W P ×ΔP+W c ×ΔC.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
