[0001] The present invention relates to the technical field of dynamic compaction filling construction, and more particularly to a dynamic compaction filling construction process for red clay soil based on construction section zoning. Background Art

[0002] Red clay is a special soil widely distributed in the Yunnan-Guizhou Plateau, eastern Sichuan, the two lakes, and northern Guangdong and Guangxi regions of my country. It has the characteristics of high natural water content and low density. When building an airport in a red clay area, if fillers with properties that are significantly different from those of the red clay are selected, it will cause excessive settlement and affect the project. In order to make full use of the excavated material source, it is necessary to reasonably select filling materials, and it is necessary to fully consider the characteristics of red clay and select appropriate dynamic compaction filling construction technology to avoid engineering problems such as excessive differential settlement caused by differences in filler properties.

[0003] Therefore, it is necessary to propose a red clay soil dynamic compaction filling construction process based on construction section zoning to at least partially solve the problems existing in the prior art. Summary of the Invention

[0004] The Summary of the Invention introduces a series of simplified concepts that will be further described in the Detailed Description of the Invention. The Summary of the Invention is not intended to limit the key features and essential features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0013] Among them, the initial tamping parameters include: initial strong tamping energy level, initial drop distance of the tamping hammer, initial single-point tamping number and initial tamping point number.

[0014] Preferably, the filling material in the excavation area includes soil, stone and soil-stone mixture.

[0015] Preferably, the construction area is filled to a set thickness, including:

[0016] Determine the filling thickness of each layer based on the set thickness and number of filling layers;

[0017] Based on the filling thickness of each layer, the backfill method is used to fill the construction area in layers to the set thickness. The red clay layer formed is located between the two adjacent excavation area filling layers.

[0018] Among them, after each layer is filled, its top surface is flattened.

[0019] Preferably, the construction area after filling is compacted according to the determined compaction parameters, including:

[0020] Import the tamping point layout and spacing of the construction area into the control terminal and display them;

[0021] The control terminal locates the horizontal position, elevation and direction of the compaction machine body and the compaction hammer, and moves the compaction hammer to the corresponding position above the compaction point;

[0022] The tamping points are tamped according to the initial tamping parameters, and the number of tamping times, the drop distance of the tamping hammer and the strong tamping energy level of each tamping point are recorded.

[0023] Preferably, the standard for stopping the hammer when tamping the tamping point is controlled so that the average settlement of the last two strikes is less than or equal to a preset settlement.

[0030] When the number of tamping is less than the initial single-point tamping number, if the settlement of each tamping is greater than the first design settlement, and the water content of the red clay corresponding to this tamping point is greater than the set water content, then the initial drop distance is reduced and the initial dynamic compaction energy level is reduced;

[0036] If the predicted number of remaining tamping blows is greater than 2 and the average settlement of the last two blows in the first n tamping blows is less than 3 cm, the initial dynamic compaction energy level needs to be increased.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0045] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0046] like Figure 1-Figure 3 As shown, the present invention provides a red clay soil dynamic compaction filling construction process based on construction section zoning, comprising:

[0047] Determining design parameters for the construction area; wherein the design parameters include filling materials, filling parameters, and dynamic compaction parameters, and the filling materials include at least one excavation area filler and red clay;

[0048] Process the original foundation 1 of the construction area, measure the elevation of the construction area, and set elevation control points;

[0049] Fill the construction area to the set thickness based on the determined filling materials and filling parameters;

[0050] According to the determined dynamic compaction parameters, the construction area after filling is compacted and the elevation of the construction area after dynamic compaction is measured;

[0051] The construction results of the construction area are tested. When the construction results meet the design requirements, the entire construction section can be constructed according to the design parameters.

[0052] The entire construction section can be divided into multiple construction areas according to construction needs.

[0053] Furthermore, the filling parameters include: the number of filling layers and the filling materials of each layer;

[0054] The number of filling layers is greater than or equal to three, and the material of at least one of the multiple layers is red clay.

[0055] Furthermore, the filling material in the excavation area includes: soil, stone and soil-stone mixture.

[0056] During actual construction, construction preparations need to be made first, that is, the design parameters of the construction area need to be determined.

[0057] Then the surveying and layout is carried out, that is, GPS is used to determine the layout of the filling area according to the requirements of the construction drawings, the filling range is spread out with gray lines, and coordinate control network foundation piles are set outside the filling range. At the same time, leveling points are reasonably arranged around it as a basis for controlling the elevation and measuring the settlement of the compacted filling body; before filling, the elevation of the construction area needs to be measured first and records should be kept.

[0058] After measurement and layout, the original foundation 1 is treated to meet the requirements of dynamic compaction, that is, the site is flat, relatively dense, hard, and the site itself has small settlement and deformation. After the original foundation 1 is treated and meets the requirements of dynamic compaction, filling construction can be carried out to reduce the impact of the original foundation 1 on the dynamic compaction fill body, and the elevation of the construction area after the original foundation 1 is treated is measured, and elevation control points are set.

[0059] After the original foundation 1 is treated, fill the construction area in layers using the backfill method to the set thickness;

[0060] Specifically, the construction area is filled to a set thickness, including:

[0061] Determine the filling thickness of each layer based on the set thickness and number of filling layers;

[0062] Based on the filling thickness of each layer, the backfill method is used to fill the construction area in layers to the set thickness. The red clay layer 3 formed is located between the two adjacent excavation area filling layers.

[0063] Among them, after each layer is filled, its top surface is flattened.

[0064] For example, Figure 1 As shown, it is divided into three layers. The excavation area is filled with soil-rock mixture. From bottom to top, soil-rock mixture, red clay and soil-rock mixture are filled in sequence to form soil-rock mixture layer 2, red clay layer 3 and soil-rock mixture layer 2. The filling thickness of each layer is not less than 1.3 meters, and the set thickness is 4 meters. After each layer is filled, a bulldozer is used to flatten it. After all three layers are filled, the filling thickness is 4 meters. After flattening, dynamic compaction can be carried out.

[0065] During dynamic compaction, perform dynamic compaction according to the determined dynamic compaction parameters. After dynamic compaction, measure the elevation of the construction area.

[0066] During the entire construction process, the elevation before filling (i.e. the elevation of the original foundation 1), the elevation when filling is completed, the filling thickness, the elevation after dynamic compaction, and the settlement after dynamic compaction are recorded. After the construction is completed, the construction results of the construction area are inspected to check whether the dynamic compaction filling construction meets the solid volume ratio, dry density and compaction indicators in the design requirements. If all are met, the entire construction section is constructed according to the construction process of the construction area to ensure the quality of the dynamic compaction filling construction in the entire construction section.

[0067] During construction, the red clay layer 3 is selected to be located between the two layers of soil-rock mixture 2, which can avoid direct exposure of the red clay. The soil-rock mixture is used to constrain the red clay, which can fully utilize the material resources in the excavation area while reducing settlement. First, a construction area is selected for construction. Then, when the construction results of the construction area meet the design requirements, the entire construction section is constructed according to the design parameters based on construction experience, which can ensure construction quality.

[0068] In one embodiment, the dynamic compaction parameters include: set filling thickness, compaction point arrangement, compaction point spacing, compaction type and initial compaction parameters;

[0069] Among them, the initial tamping parameters include: initial strong tamping energy level, initial drop distance of the tamping hammer, initial single-point tamping number and initial tamping point number.

[0070] For example, Figure 2 In the top view shown in the figure, in a certain project, the construction area is 625 square meters, that is, Figure 2 The area of ​​the inner square is 25 meters long. The slope is 1:2 and the outer square is formed. The side of the outer square is 41 meters long. The distance between the adjacent sides of the outer square and the inner square is 8 meters.

[0071] The set thickness of the filling is 4 meters, and the tamping points are arranged in a square, that is, Figure 3 The circles shown are tamping points, the squares are construction areas, the tamping points are spaced 4 meters apart, and the tamping type is point tamping. The initial tamping energy level is 2500-3500 kNm, preferably 3000 kNm. The initial single-point tamping number is 8-12, and the initial point tamping number is 1.

[0072] The above parameters may be pre-set parameters, and when performing dynamic compaction, the set dynamic compaction parameters can be used for dynamic compaction; or, some of the above parameters may be adaptively adjusted, for example, the initial dynamic compaction energy level, the initial drop distance of the rammer, and the initial single-point compaction number may be adaptively adjusted based on the real-time detected data during the dynamic compaction process to improve the dynamic compaction quality.

[0073] In one embodiment, the construction area after filling is compacted according to the determined compaction parameters, including:

[0074] Import the tamping point layout and spacing of the construction area into the control terminal and display them;

[0075] The control terminal locates the horizontal position, elevation and direction of the compaction machine body and the compaction hammer, and moves the compaction hammer to the corresponding position above the compaction point;

[0076] The tamping points are tamped according to the initial tamping parameters, and the number of tamping times, the drop distance of the tamping hammer and the strong tamping energy level of each tamping point are recorded.

[0077] Before carrying out dynamic compaction, the layout of the compaction points and the distance between the compaction points in the construction area are first imported into the control terminal and displayed. There is no need to manually place points in the construction area, which improves work efficiency. The control terminal is equipped with a digital monitoring system for the dynamic compaction machine, which can monitor the construction data of the dynamic compaction machine, so as to accurately guide the rammer to carry out dynamic compaction work, facilitate the operator to carry out construction, and improve work efficiency. In addition, the construction data of the dynamic compaction machine can be transmitted to the control terminal in real time, and a construction progress report, a construction quality report, a dynamic compaction machine working condition report, etc. can be generated for the construction personnel to view.

[0078] In one embodiment, the criterion for stopping the hammer when tamping the tamping point is controlled such that the average settlement of the last two strikes is less than or equal to a preset settlement.

[0079] In a certain project, the preset settlement is set to 5cm, that is, the hand hammer standard is controlled according to the average settlement of the last two blows being less than or equal to 5cm to ensure the uniformity of compaction.

[0080] In one embodiment, performing dynamic compaction on the filled construction area according to the determined dynamic compaction parameters further includes:

[0081] The compaction points are compacted according to the initial compaction parameters, and the compaction data are collected in real time;

[0082] Adjust the initial tamping parameters based on the dynamic tamping data collected in real time;

[0083] The adjusted ramming parameters are used as the initial ramming parameters for the next ramming to continue ramming, and the above steps are repeated after the next ramming is completed.

[0084] Based on the determined compaction parameters, the construction area after filling is compacted. During the compaction, each compaction point is compacted using the determined compaction parameters, and the compaction parameters are not adjusted during this process; or, using the solution of this embodiment, the initial compaction parameters are adjusted based on the compaction data collected in real time, so as to make adaptive adjustments according to the differences of each compaction point and each compaction of the same compaction point, so as to improve the quality of compaction.

[0085] There are two options for adjusting the initial ramming parameters, as follows:

[0086] In the first solution, dynamic compaction data includes the settlement of each compaction, the shape of the compaction pit, and the moisture content of the red clay. The initial compaction parameters are adjusted based on the real-time dynamic compaction data, including:

[0087] Obtain the ratio of pit depth to pit diameter based on the ramming pit shape;

[0088] The ramming pit morphology can be determined by installing a binocular vision camera on top of the dynamic ramming machine. This camera can obtain a 3D point cloud model of the ramming pit formed by ramming, and then calculate the pit depth (depth) and pit diameter (diameter) ratio. To obtain the moisture content of the red clay, an infrared spectrometer can be installed in front of the bulldozer during red clay filling. During the leveling process, the moisture content of the red clay layer 3 can be measured. A point can be detected every 5 square meters, and the detected point can be matched with the area where the ramming point is located.

[0089] When the number of tamping is less than the initial single-point tamping number, if the settlement of each tamping is greater than the first design settlement, and the water content of the red clay corresponding to this tamping point is greater than the set water content, then the initial drop distance is reduced and the initial dynamic compaction energy level is reduced;

[0090] For example, if the first design settlement is set to 7 cm and the water content is set to 22%, if the settlement of a certain compaction is greater than 6 cm and the water content of the red clay corresponding to this compaction point is greater than 22%, it indicates that the fill is too soft and prone to excessive settlement. In this case, the initial drop distance needs to be reduced by 1 to 2 meters, and the initial compaction energy level of the single point needs to be reduced by 5 to 15%.

[0091] When the number of tamping blows is greater than 3 and less than the initial single-point tamping blow number, if the settlement of each tamping blow is less than the second design settlement, and the ratio of the pit depth to the pit diameter is less than the set ratio, then the initial dynamic compaction energy level is increased; wherein the second design settlement is less than the first design settlement;

[0092] For example, the second design settlement is designed to be 3 cm, and the set ratio is designed to be 0.4-0.8, preferably 0.6. If the settlement of a certain tamping is less than 3 cm, and the ratio of pit depth to pit diameter is less than 0.6, it indicates that the soil is too hard and the penetration force needs to be enhanced. At this time, the initial drop distance needs to be increased by 1 meter to 2 meters (not exceeding the maximum drop distance that the dynamic compaction machine can withstand), and the initial dynamic compaction energy level of the single point needs to be increased by 5% to 20%;

[0093] If neither of the above two situations is true, there is no need to adjust the initial tamping parameters. The current tamping parameters are maintained and the tamping is continued until the initial single-point tamping number is reached, and the tamping is stopped; wherein, the initial single-point tamping number is 8 to 12.

[0094] In the first option, the main focus is on adjusting the initial drop distance and initial strong compaction energy level of the rammer to prevent unreasonable design of the initial strong compaction energy level and initial drop distance, which may lead to over-compaction or insufficient strong compaction, thereby ensuring the quality of strong compaction construction and improving the construction effect of the construction area.

[0095] The second solution is to adjust the initial tamping parameters based on the real-time collected dynamic tamping data, including:

[0096] Before the n+1th tamping, the remaining number of tamping is predicted based on the dynamic tamping data of the first five tampings, where n is greater than 4;

[0097] The dynamic compaction data include one or more of the following: average settlement of the last two strikes, moisture content, previous settlement rate, energy accumulation value and soil-rock ratio;

[0098] The average settlement of the last two strikes is used to indicate the compressive plasticity of the soil. The moisture content, that is, the moisture content of the red clay layer 3 corresponding to the current tamping point, is used to indicate the fluidity of the soil. The early settlement rate, that is, the linear fitting slope of the settlement of the first three strikes, is half of the difference between the settlement of the third strike and the settlement of the first strike, and is used to indicate the initial density. The energy accumulation value, that is, the sum of the dynamic compaction energy levels of the first n strikes, is used to indicate the soil absorption capacity. The soil-rock ratio, that is, the ratio of soil to rock, is used to indicate the influencing factor of aggregate shear strength.

[0099] The remaining number of tamping blows can be predicted using a trained prediction model, such as an LSTM model (long short-term memory network model);

[0100] If the predicted number of remaining tamping strokes is less than or equal to 0.5, and the average settlement of the last two strokes of the first n tamping strokes is less than or equal to 5 cm, then stop tamping;

[0101] For example, if the predicted number of remaining tamping strokes is 0.3 and the average settlement of the last two strokes in the first n tamping strokes is 4.5 cm, then stop tamping;

[0102] If the predicted number of remaining tamping blows is greater than 2, and the average settlement of the last two blows in the first n tamping blows is less than 3 cm, the initial dynamic compaction energy level needs to be increased;

[0103] For example, if the predicted number of remaining tamping blows is 3.2 and the average settlement of the last two blows in the first n tamping blows is 2.5 cm, then the initial dynamic compaction energy level is increased and the remaining 3 to 4 tamping blows are completed;

[0104] If the predicted number of remaining tamping strokes is greater than 0.5, and the average settlement of the last two strokes in the first n tamping strokes is normal, then continue to complete the remaining number of tamping strokes;

[0105] For example, if the predicted number of remaining tamping is 1.5 and the average settlement of the last two tampings in the first n tampings is 5 cm, then continue to complete the remaining 1 to 2 tampings.

[0106] In the second option, the remaining number of tamping times and the initial tamping energy level are adjusted mainly through the tamping data of the first five tamping times, so as to reduce the energy consumption of the tamping machine while ensuring the quality of tamping.

[0107] In addition, the second option can be combined with the first option. After the number of tamping reaches 5 times in the first option, the second option can be used to continue to adjust and optimize the initial single-point tamping number, further optimize the initial tamping parameters, reduce the energy consumption of the tamping machine, and improve the quality of tamping.

[0108] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the present invention, the present invention is not limited to the specific details and illustrations shown and described herein.
