[0047] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0048] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0049] In the vast desert and its surrounding arid areas, there is a lack of ideal road construction materials, such as clay and gravel, but aeolian sand resources are extremely abundant and have huge reserves. Therefore, aeolian sand can be used as a unique road construction material. It can not only use local materials and greatly reduce costs, but also has obvious environmental benefits.

[0050] However, due to the high fluidity of aeolian sand, it is easily affected by external factors (such as rain and wind), resulting in poor roadbed stability. Therefore, how to effectively monitor roadbed deformation and adjust and test it through scientific compaction process construction procedures has become the key to ensuring the stability of aeolian sand high fill roadbed.

[0051] Based on the above questions, please refer to Figures 1 to 4 The embodiment of the present invention provides a method for monitoring the stability of aeolian sand high-fill roadbed 100. It conducts research on deformation monitoring, control and evaluation of roadbed 100 for high-fill roadbeds constructed with aeolian sand filling. It also uses dry pressing construction procedures and strict tests, combined with continuous monitoring of embankment settlement and lateral displacement, to reveal the deformation law of high-fill roadbeds during the entire construction process through these monitoring data. At the same time, combined with indoor tests, on-site testing, construction process monitoring, post-construction settlement monitoring, and numerical calculation methods, a set of construction control technologies for aeolian sand high-fill roadbeds and practical methods for embankment stability monitoring are constructed.

[0052] This monitoring method is highly adaptable and practical. It adopts aeolian sand dry compaction construction technology according to local conditions, solves the problem of water shortage in the project, and significantly reduces the cost of road construction. Based on a deep understanding of the unique properties of aeolian sand, suitable desert mechanical construction equipment is selected to ensure the maximum mechanical efficiency. During the construction of high-fill aeolian sand embankment, precise roadbed 100 deformation monitoring and control measures are adopted for aeolian sand filling construction. Through scientific adjustment and testing of the dry compaction construction process, a solid theoretical basis is provided for the construction of high-fill dry compaction roadbed 100.

[0053] In detail, the method for monitoring the stability of aeolian sand high fill roadbed 100 provided in an embodiment of the present invention comprises the following steps:

[0054] Step S100, using a high fill roadbed 100 dry compaction method to fill the aeolian sand high fill roadbed 100;

[0055] Step S200, setting a sensor device on the roadbed 100 to monitor the status information of the roadbed 100 in real time;

[0056] Step S300 , transmitting the status information to the server for processing and determining the stability of the roadbed 100 .

[0057] In this embodiment, the status information includes at least one of the settlement information of the roadbed 100, the displacement information of the roadbed 100 section in the horizontal and vertical directions, and the environmental information. Therefore, by acquiring the settlement information of the roadbed 100, the displacement information of the roadbed 100 section in the horizontal and vertical directions, and the environmental information in real time, and transmitting them to the cloud server for data processing and analysis, so as to monitor the deformation and stability of the roadbed 100 in real time and accurately, not only can potential problems be discovered in time and corresponding measures be taken to reduce the resulting road damage and accident risks, that is, to discover and solve the stability problems of the filled roadbed 100 in advance, effectively avoiding the high cost of repair and maintenance in the later stage, but also the wind-blown sand dry pressing construction process can be effectively and targetedly adjusted to build a more sturdy and durable highway, providing a strong guarantee for the convenience and stability of traffic.

[0058] Furthermore, step S100 also includes:

[0059] In sub-step S110 , multiple layers of aeolian sand are filled on a preset road surface, and each layer of aeolian sand is compacted after being filled to form a multi-layer aeolian sand filling layer 110 .

[0060] In this embodiment, during the filling process of the embankment, the principle of full width of the cross section and longitudinal stratification needs to be followed. The loose laying thickness needs to be controlled at 50 cm to ensure that the layer thickness after compaction does not exceed 45 cm. When faced with the situation of uneven original ground, it is preferred to start from the lowest point, fill in layers horizontally, and gradually advance to the middle.

[0061] In order to ensure the compaction quality of the entire section of the roadbed 100, the wind-blown sand roadbed 100 needs to be widened by 50cm on each side for construction, and this part is constructed simultaneously with the main filling to ensure uniform compaction. The transportation method of wind-blown sand will be determined based on the actual situation on site. For shorter transportation distances, bulldozers are mainly used for pushing and leveling.

[0062] Specifically, in the initial compaction stage, the initial compaction of the aeolian sand roadbed 100 adopts the dry compaction method, that is, compaction is performed under the natural moisture content state. From the bottom to the top of the roadbed 100, each layer is rolled twice by a bulldozer during the layered leveling process to ensure the initial compaction effect; and in the final compaction stage, for each layer below the top surface of the roadbed, a D9 model and above medium-sized bulldozer can be used for three times of rolling, and a 22T model double-drive vibratory roller is used for the top surface of the roadbed, first for one static compaction, then for vibration compaction, and finally for one static compaction to finish.

[0063] Sub-step S120, using a water-immersed ring knife method to detect the compaction degree of the formed road base;

[0064] Determine whether the compaction degree meets the standard;

[0065] If the standard is not met, the aeolian sand filling layer 110 continues to be compacted.

[0066] In this embodiment, it can be understood that the water-immersed ring knife method is mainly used to determine the dry density and water content of the soil sample. Its basic principle is to determine the volume of the soil sample by measuring the amount of water discharged after the soil sample is completely immersed in water, and then calculate the density of the soil sample. This method is of great significance for understanding the physical properties of soil, evaluating soil compaction, and engineering design.

[0067] Therefore, the compaction degree is tested by using the water-immersed ring knife method, and the part of the roadbed 100 that does not meet the compaction degree requirements is promptly supplemented with pressure until the compaction degree meets the design requirements.

[0068] It should also be noted that after the roadbed 100 is filled to the designed elevation, the slope is brushed from top to bottom according to the designed slope gradient and position, and the wind-blown sand generated after the slope is flattened on the spot outside the slope foot. After the slope is brushed, protective construction is carried out to ensure that each section of the roadbed 100 is protected.

[0069] Furthermore, step S200 further includes:

[0070] Sub-step S210, a layered settlement monitoring sensor 200 is provided in each aeolian sand filling layer 110 to obtain settlement information of the roadbed 100;

[0071] In sub-step S220, a guide wheel inclinometer 300 is arranged in each aeolian sand filling layer 110 to obtain displacement information of the roadbed 100 in the horizontal and vertical directions.

[0072] In this embodiment, the displacement and settlement data of the aeolian sand roadbed 100 can be conveniently and accurately measured through the stratified settlement monitoring sensor 200 and the guide wheel inclinometer 300, providing more reliable reference data for subsequent construction, and being able to more clearly and intuitively analyze the stratified settlement, uneven settlement, deep horizontal displacement / soil stress and induced settlement of the roadbed 100, thereby facilitating targeted adjustment of the dry compaction method of the high fill roadbed 100 and timely maintenance of the roadbed 100, thereby improving the construction progress and engineering quality control of the aeolian sand roadbed 100, and improving construction efficiency and quality.

[0073] Furthermore, before step S100, the method further includes:

[0074] Step S400, setting a planar fixed layer 400 on a preset road surface;

[0075] In this embodiment, since the bottoms of the stratified settlement monitoring sensor 200 and the guide wheel inclinometer 300 must be located on the fixed layer, when the foundation of the construction roadbed 100 is rolled and paved, it is necessary to form at least two planar fixed layers 400 with a specification of 100cm×100cm at 1m from the shoulder, and at least two planar fixed layers 400 are arranged at intervals of 3-5m in the extension direction of the route.

[0076] In detail, 2 points can be set in each aeolian sand roadbed section, for a total of 4. The plane fixed layer 400 can be a prefabricated 20cm thick concrete slab, or a steel plate (thickness greater than 3mm) instead, and the plane fixed layer 400 should not be higher than the foundation elevation, so as to facilitate subsequent layer-by-layer filling and rolling.

[0077] Step S210 and step S220 are implemented by the following steps:

[0078] Drill holes on both sides of the center line of the roadbed 100 in the vertical direction so that the drilled holes correspond to the planar fixed layer 400;

[0079] Settling pipes are arranged in some of the holes, stratified settlement monitoring sensors 200 are installed in the settling pipes, and the holes and the settling pipes are filled with fine sand;

[0080] Inclinometer tubes are set in other holes, guide wheel inclinometers 300 are installed in the inclinometer tubes, and cement mortar is backfilled into the holes.

[0081] In this embodiment, for the stratified settlement monitoring sensor 200, the plane fixed layer 400 needs to be positioned first. The plane fixed layer 400 corresponding to the point can be accurately found through PTK, and the hole can be drilled and pre-embedded for installation. The drilling can be done by a drilling rig, with a hole diameter of 108mm and a hole depth of 108mm to the specified pre-embedded plane fixed layer 400; and for the guide wheel inclinometer 300, the plane fixed layer 400 corresponding to the point can be accurately found through the total station at 3-5m away from the stratified settlement hole position, and the drilling can be done by a drilling rig, with a hole diameter of 108mm and a hole depth of 108mm to the specified pre-embedded plane fixed layer 400.

[0082] In detail, the installation method of the stratified settlement monitoring sensor 200 is as follows: determine the installation position, drill holes for installation, and use a drilling rig to drill holes with a hole diameter of 108mm; determine the instrument installation depth and configure the appropriate PVC long measuring tube for assembly; tear off the waterproof protective tape on the top of the instrument to prevent loss or confusion with the magnetic cores of other stratified settlement meters; dock the extended measuring rod 220; determine the position of each layer, calculate the required number of extension rods, cut the extension rods and assemble them, and lead the instrument wires out from the inside of the tube; assemble the bottom instrument and extension rod, tighten them with screws, and put them into the hole; and so on, install the instruments of other levels and fill them with fine sand; after completing the installation of the settlement tube, fill the hole and the instrument pores with fine sand until they are full.

[0083] The installation method of the guide wheel inclinometer 300 is as follows: select ABS / PVC / aluminum alloy inclinometer tubes with a length of 2m each, connect each inclinometer tube through a pipe joint, fix the joint and the inclinometer tube by drilling screws, and connect other inclinometer tubes in turn; four notches are set in the wall of the inclinometer tube to fix the pulley of the inclinometer probe. When the inclinometer tube is connected, the grooves of each section of the inclinometer tube are aligned so that the pulley of the inclinometer probe can be lowered smoothly; install the bottom cover at the bottom of the inclinometer tube, and then connect the inclinometer tube section by section, and lower it into the inclinometer hole section by section; after the inclinometer tube is lowered, backfill with cement mortar, in which the sand ratio is 2:1, and it is diluted with water to facilitate flowing into the gap outside the inclinometer tube, thereby fixing the inclinometer tube.

[0084] Furthermore, step S200 further includes:

[0085] A collection box 500 is provided at the shoulder position between the stratified settlement monitoring sensor 200 and the guide wheel inclinometer 300 , and the status information of the roadbed 100 detected by the stratified settlement monitoring sensor 200 and the guide wheel inclinometer 300 is received and sent through the collection box 500 .

[0086] In this embodiment, in order to ensure the accuracy and stability of data collection, the collection box 500 is placed outside the road shoulder without being disturbed by construction.

[0087] Furthermore, if Figure 5 As shown, the stratified settlement monitoring sensor 200 includes a mounting member 210, a measuring rod 220, a temperature sensor 230 and a processor 240. The mounting member 210 is provided with a slide groove 211, and a coil 250 is provided in the slide groove 211. One end of the measuring rod 220 is used to be inserted into the aeolian sand roadbed 100, and the other end can be slidably arranged in the slide groove 211. The temperature sensor 230 and the processor 240 are both arranged on the mounting member 210, and the coil 250 is electrically connected to the processor 240.

[0088] In this embodiment, the coil 250 is in a spiral state at the slide groove 211, so that the change in the position of the measuring rod 220 will cause the change in the inductance of the coil 250, thereby causing the change in the output frequency of the processor 240. After measuring the frequency, the change in the position of the measuring rod 220 can be calculated in combination with the corresponding calibration coefficient, and the settlement of the corresponding aeolian sand roadbed can be measured.

[0089] Since the stratified settlement monitoring sensor 200 has a high accuracy but is affected by the ambient temperature, a temperature sensor 230 is packaged in the mounting member 210 to measure the temperature and perform temperature compensation. The processor 240 can also be used to store calibration coefficients and measurement data.

[0090] like Figure 6 As shown, the inclination information is obtained by multiple guide wheel inclinometers 300 serially hoisted in the inclinometer tube, and the inclination angle or displacement of the measured structure is measured through the inclination sensor in the measuring rod 220 at different elevations.

[0091] Specifically, the inclinometer principle is as follows: Figure 7 As shown in the figure, when the structure being measured tilts and deforms, the fixed inclinometer will sense the deformation synchronously, and the deformation at a certain depth △i has the following relationship with the output angle change θ:

[0092] △i=L*sinθi

[0093] Where: △i is the displacement change at a certain depth, unit: mm;

[0094] Li is the step distance of a certain depth measurement point, in mm;

[0095] θi is the change in angle at a certain depth, unit: °;

[0096] The horizontal displacement Si at a certain depth has the following relationship with △i: Si=∑△i=△1+△2+....△i.

[0097] In detail, the collection frequency of the stratified settlement monitoring sensor 200 and / or the guide wheel inclinometer 300 is at least 120 minutes per time.

[0098] Furthermore, step S200 further includes:

[0099] A wind speed and direction finder is installed beside the roadbed 100 to obtain wind speed and direction information;

[0100] An air temperature and humidity meter is set up beside the roadbed 100 to obtain humidity and temperature information.

[0101] Specifically, the data collection frequency of the wind speed and direction finder and the air temperature and humidity meter is at least 10 minutes per time.

[0102] Furthermore, a remote automated monitoring system 600 may be provided, through which the conditions of the road section to be tested may be detected in real time.

[0103] In summary, an embodiment of the present invention provides a method for monitoring the stability of aeolian sand high fill roadbed 100, which obtains the settlement information of the roadbed 100, the displacement information of the roadbed 100 section in the horizontal and vertical directions, and the environmental information in real time, and transmits them to the cloud server for data processing and analysis, so as to monitor the deformation and stability of the roadbed 100 in real time and accurately. It can not only timely discover potential problems and take corresponding measures to reduce the road damage and accident risks caused by them, that is, discover and solve the stability problems of the fill roadbed 100 in advance, effectively avoiding the high repair and maintenance costs in the later stage, but also can effectively and targetedly adjust the aeolian sand dry pressing construction process to build a more sturdy and durable highway, providing a strong guarantee for the convenience and stability of traffic.
