Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to a device for real-time monitoring of roadbed filling depth and uniformity. Background Art

[0002] Roadbed filling refers to the operation of filling the roadbed during road construction to ensure the flatness and stability of the road surface. In some cases, roadbed filling requires piling, which can provide more support for the roadbed, thereby increasing the bearing capacity and anti-settling ability of the roadbed. After the piles are driven, a close connection can be formed between the piles and the soil, which can greatly improve the stability and safety of the roadbed. In addition, piling can isolate the roadbed from the groundwater level, reduce the impact of moisture on the roadbed, and at the same time, it can also strengthen the compactness of the roadbed and reduce soil deformation.

[0003] The cement mixing pile drilling rig is a mechanical equipment specially used in construction projects. It mixes cement, sand, stone and other materials and pours them into the hole to form cement slurry and complete the construction of bored piles. It is mainly composed of a frame, a drill rod system, a hydraulic system and a motor system. Among them, the frame is used to support the entire equipment, the drill rod system is the main component for mixing and drilling, the hydraulic system provides power for the drilling rig, and the motor system drives the operation of the entire equipment. In the process of drilling to the designed depth under the cement mixing pile drilling rig, the filling depth and filling uniformity are monitored, which can accurately control the filling depth of the cement mixing pile and the overall strength of the pile body to ensure that each pile meets the design requirements.

[0004] However, due to the special foundation conditions, especially when facing soft soil foundation, the problems of poor hardness and insufficient bearing capacity are particularly prominent. Although the foundation has been leveled before construction, it is still difficult to completely avoid the sinking of the cement mixing pile machine during the construction of the cement mixing pile machine and the cement mixing pile drilling rig. This sinking will cause the drill shaft of the drilling rig to deviate, making it difficult for the drill shaft to maintain the proper verticality, directly affecting the accuracy of monitoring the filling depth and the distribution uniformity of the cement slurry, making it difficult for construction personnel to accurately judge the actual filling height of the pile body, resulting in insufficient or excessive pile body depth, affecting the overall strength and stability of the pile body, not only reducing the overall strength of the pile body, but also may cause defects such as cavities or cracks inside the pile body, seriously affecting the quality and durability of the pile body. Therefore, it is necessary to propose a real-time monitoring device for the depth and uniformity of the roadbed filling, which can monitor whether the drilling rig is offset, and perform depth monitoring feedback adjustment and cement slurry spraying adjustment according to the offset. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a real-time monitoring device for roadbed filling depth and uniformity. By monitoring the angle and drilling depth of the drill rod, when there is an offset caused by the drilling of the drilling rig, the offset depth generated in the process is converted into a relative depth according to the drilling depth and angle, thereby improving the accuracy of depth monitoring.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a real-time monitoring device for the depth and uniformity of roadbed filling, comprising a support platform and a lifting platform, a gap is provided between the support platform and the lifting platform, a frame is provided in the gap, a hydraulic system for providing drilling force is provided on the top of the frame, a drill rod is slidably connected in the frame, a spraying assembly for cement slurry transportation and spraying is provided inside the drill rod, and a detection assembly for detecting the uniformity of cement slurry is provided in the spraying assembly;

[0007] A depth sensor is fixedly connected to the outer wall of the drill pipe, and the depth sensor signal is connected to the control system. A tilt sensor is also fixedly connected to the top of the outer wall of the drill pipe, and the tilt sensor is connected to the control system signal.

[0008] The control system includes a depth unit and a uniformity unit for monitoring uniformity and controlling and adjusting the degree of agitation;

[0009] The depth unit includes a depth monitoring module, a dip marking module, a dip acquisition module and a depth conversion module;

[0010] A depth monitoring module is used to collect the drilling depth of the drill rod through a depth sensor;

[0011] The inclination marking module is used to record and transmit the information of the occurrence of drill pipe inclination and record the drilling depth after the inclination begins;

[0012] The inclination angle acquisition module is used to acquire the drilling angle of the drill rod during the drilling process through the inclination sensor;

[0013] The depth conversion module is used to convert the relative depth according to the collected drill rod inclination angle and the drilling depth after the inclination starts.

[0014] The technical principles of the above scheme are as follows:

[0015] During the construction process, the drill rod is supported by the frame and powered by the hydraulic system for drilling and mixing. The depth sensor monitors the depth changes of the drill rod in real time and sends the data to the control system. At the same time, the tilt sensor monitors the tilt angle of the drill rod in real time to ensure the verticality of the drill rod. When the frame is tilted or the drill rod depth does not meet the requirements, the control system will automatically issue an alarm. The detection component detects the water content of the cement slurry to monitor the mixing effect of the cement slurry, realizing real-time monitoring and feedback of depth and uniformity. The spraying component sprays the cement slurry evenly in the filling area to ensure the overall strength and stability of the pile body.

[0016] The above scheme has the following beneficial effects:

[0017] 1. In this solution, the built-in depth sensor of the device can monitor the drilling depth of the drill rod in real time to ensure that the filling depth meets the design requirements. Through accurate data feedback, construction personnel can adjust the drilling speed of the drill rod in time to reduce the problem of insufficient or excessive depth. In addition, the tilt sensor monitors the tilt angle of the drill rod in real time to ensure that the drill rod remains vertical during the drilling process. The monitoring of the uniform unit helps to evenly distribute the cement slurry and reduce the probability of defects such as cavities or cracks inside the pile body, thereby improving the overall strength and stability of the pile body; in addition, according to the real-time monitoring data, construction personnel can accurately grasp the drilling depth and drilling angle of the drill rod, and realize accurate control of the drilling process, which helps to improve construction accuracy and ensure the accuracy and stability of roadbed filling.

[0018] 2. In this solution, the device is equipped with an advanced intelligent control system that can collect, process and analyze data from depth sensors and tilt sensors. Through the depth conversion module, the control system can automatically convert the erroneous depth recorded during tilting into relative depth, so as to reduce the risk of inaccurate depth monitoring when the frame sinks and causes drilling tilt, and improve the accuracy of depth monitoring.

[0019] 3. This solution, this device is flexibly designed and can adapt to a variety of complex foundation conditions, especially soft soil foundations. By monitoring the drilling angle of the drill rod and prompting the occurrence of tilt problems, the device can maintain stable drilling ability and verticality under different foundation hardness, so that the device can be widely used in various road construction scenarios, improving construction efficiency and project quality.

[0020] Furthermore, the depth conversion module calculates the relative depth of the drill rod after it is tilted, and the relative depth of the drill rod after it is tilted is calculated by the following formula:

[0021]

[0022] Where, d x is the relative depth of the drill pipe after it is tilted, d g is the drilling depth after tilting, θ is the tilt angle, r z is the radius of the drill pipe, f(d x ) is a preset attenuation function with d x is the attenuation coefficient obtained for the independent variable.

[0023] Beneficial effect: This solution optimizes the calculation method of depth conversion. As the drill rod goes deeper, the pressure on the pile foundation needs to increase, and the pouring of cement slurry will not stop when the drill rod is tilted. x) is taken as the attenuation of the bearing strength, and the relative depth after inclination is converted to improve the rationality of depth monitoring.

[0024] Furthermore, the outer wall of the drill pipe is covered with a wear-resistant layer.

[0025] Beneficial effects: The wear-resistant layer can significantly improve the wear resistance of the drill pipe during use and extend the service life of the drill pipe. During long-term drilling operations, the drill pipe will produce friction with the soil and rocks. The wear-resistant layer can effectively reduce the loss of the drill pipe body caused by this friction, reduce the frequency of replacing the drill pipe, and thus reduce maintenance costs.

[0026] Furthermore, the inclination marking module includes an indicator light, which is fixedly connected to the outside of the frame. When the drill rod is tilted during drilling, the inclination marking module sends a signal to drive the indicator light to start and turn red.

[0027] Beneficial effects: When the drill rod tilts during the drilling process, the inclination marking module can quickly sense and send a signal, and the driving indicator light will immediately start and turn red; this instant warning function allows the operator to discover the inclination of the drill rod at the first time, so as to take timely measures to adjust it, so as to avoid the continued expansion of the inclination and cause construction quality problems. In addition, through the precise monitoring and instant feedback of the inclination marking module, the operator can more accurately grasp the inclination state of the drill rod, and then make more precise adjustments during the construction process, which will help to improve the depth and uniformity of the roadbed filling and ensure that the overall strength and stability of the pile body meet the design requirements.

[0028] Furthermore, a plurality of variable-angle winglets are provided circumferentially on the outer wall of the drill rod, and the variable-angle winglets include a fixing frame fixedly connected to the drill rod, a sleeve is fixedly connected to one end of the fixing frame away from the drill rod, a stirring blade is rotatably connected to the end of the sleeve away from the drill rod, a driving component for driving the stirring blade to rotate is fixedly connected inside the sleeve, and the driving component is connected to the control system signal.

[0029] Beneficial effects: The design of variable-angle winglets enables the stirring blades to adjust their angles according to construction requirements, thereby achieving more uniform stirring while the drill rod is drilling. This design can ensure a more complete mixing of materials such as cement, sand, and stone, and improve the overall strength and stability of the pile. In addition, through the signal connection between the drive assembly and the control system, construction personnel can remotely control the rotation and angle adjustment of the stirring blades, allowing the device to adapt to different construction environments and geological conditions, thereby improving construction efficiency and quality.

[0030] Furthermore, the spraying assembly includes a slurry transport pipe embedded in the drill rod, a slurry outlet is opened at the bottom end of the drill rod, and the slurry transport pipe is detachably connected to the slurry outlet.

[0031] Beneficial effects: The slurry transport pipe is embedded in the drill rod and is detachably connected to the slurry outlet at the bottom of the drill rod. This design makes the spraying assembly more convenient and quick to install, disassemble and maintain, and improves the flexibility of construction. Construction personnel can quickly adjust or replace the slurry transport pipe according to actual needs. At the same time, the detachable connection method also helps to avoid blockage or leakage of cement slurry during transportation, further ensuring the construction quality. In addition, by transporting cement slurry to the slurry outlet at the bottom of the drill rod through the slurry transport pipe, uniform spraying of cement slurry can be achieved. This design helps to ensure uniform distribution of cement slurry in the pile hole, thereby improving the overall strength and stability of the pile body.

[0032] Furthermore, the detection component includes a cement sensor, which is fixedly connected to the inner wall of the slurry transport pipe and is connected to the control system signal.

[0033] Beneficial effects: The cement sensor is fixedly connected to the inner wall of the slurry transport pipe and can directly contact the flowing cement slurry, so as to accurately sense the key parameters of the cement slurry such as water content and density. Through the signal connection between the cement sensor and the control system, the data collected by the sensor can be transmitted to the control system in real time, ensuring that the control system can obtain the real-time status of the cement slurry at the first time, providing strong data support for subsequent adjustment operations.

[0034] Further, the uniformity unit includes a uniformity monitoring module and a regulation module;

[0035] Uniformity monitoring module, used to detect the water content of cement slurry to be sprayed through cement sensor, and compare it with the standard water content of cement slurry mixed evenly;

[0036] The regulating module is used to calculate the operating power of the driving component according to the detected uniformity, and to adjust the angle of the stirring blade by controlling the driving component.

[0037] Beneficial effects: The uniformity monitoring module can monitor the moisture content of cement slurry in real time to ensure that the data is accurate and timely. By comparing with the standard moisture content, the moisture content deviation can be quickly discovered to provide a basis for subsequent adjustments. The adjustment module accurately adjusts the angle of the stirring blade according to the monitoring results, thereby improving the mixing uniformity of the cement slurry. By optimizing the cement slurry mixing process, energy waste and emissions are reduced, ensuring full utilization of cement slurry and reducing resource waste.

[0038] Furthermore, in the uniformity detection module, the standard water content of cement slurries of different strengths is a constant, and the difference between the detected water content of the cement slurry and the standard water content is calculated. When the difference is greater than 5%, the sprayed cement slurry is judged to be too thin; when the difference is less than -5%, the sprayed cement slurry is judged to be too thick; and when the difference is between 5% and -5%, the sprayed cement slurry is judged to be mixed uniformly.

[0039] Beneficial effects: By comparing the actual detected cement slurry moisture content with the preset standard moisture content, the mixing state of the cement slurry can be accurately judged. The standardized comparison method avoids the subjectivity of human judgment and improves the accuracy and reliability of judgment. The real-time feedback mechanism enables construction personnel to adjust the proportion or spraying parameters of cement slurry in time to ensure construction quality, which helps construction personnel to master the best mixing effect of cement slurry, thereby improving the quality and stability of roadbed filling.

[0040] Furthermore, in the adjustment module, when the uniformity is judged to be too thin, the control system sets the rotation signal of the driving component so that the stirring blade and the fixed frame are collinear; when the uniformity is judged to be too thick, the control system sets the rotation signal of the driving component so that the angle between the stirring blade and the fixed frame is 45°.

[0041] Beneficial effect: When the cement slurry is judged to be too thin, the control system responds quickly and makes the stirring blade and the fixed frame collinear through the driving component. The linear arrangement can enhance the radial effect of stirring and accelerate the mixing of water and solid particles in the cement slurry, thereby rapidly increasing the concentration of the cement slurry. On the contrary, when the cement slurry is judged to be too thick, the control system adjusts the driving component to form a 45° angle between the stirring blade and the fixed frame. The inclined arrangement not only provides radial stirring, but also introduces tangential stirring force, which helps to disperse the agglomeration of solid particles and improve the uniformity and fluidity of the cement slurry.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The following is further described in detail through specific implementation methods:

[0053] Embodiment 1:

[0054] As attached Figure 1 , Figure 2 , Figure 3 and Figure 5As shown: a real-time monitoring device for roadbed filling depth and uniformity, including a supporting platform 1 and a lifting platform 2, a gap is provided between the supporting platform 1 and the lifting platform 2, a frame 3 is provided in the gap, a drill rod 5 is slidably connected to the frame 3 through a slider slide structure, the drill rod 5 is pulled by a hydraulic system 4 arranged on the top of the frame 3, a slurry transport pipe 6 is embedded in the drill rod 5, a slurry outlet 7 is opened at the bottom end of the drill rod 5, the slurry transport pipe 6 of the drill rod 5 is detachably connected to the slurry outlet 7, when the drill rod 5 drills into the ground, the slurry transport pipe 6 is filled with cement slurry, and the cement slurry is thrown out from the slurry outlet 7 through the rotation of the drill rod 5, so as to realize the spraying of the cement slurry drilled synchronously, and the detachable connection is conducive to the cleaning of the slurry transport pipe 6 after the completion of the drilling and pouring, and reduces the blockage problem of the slurry transport pipe 6 caused by the solidification of cement slurry in the slurry transport pipe 6.

[0055] A cement sensor 8 for detecting the uniformity of cement slurry is welded inside the slurry transport pipe 6. The cement sensor 8 uses the capacitance principle to detect the water content of cement and can monitor the water content of cement slurry in real time, thereby helping to control the proportion of cement slurry and improve the quality of the project. Water content is a key factor affecting pile formation by drilling rigs. By real-time monitoring the water content of filling materials, it can be ensured that piles are formed within the optimal water content range, thereby improving the forming strength and uniformity.

[0056] A depth sensor 9 is welded to the outer wall of the drill rod 5, and the signal of the depth sensor 9 is connected to the control system. A tilt sensor 10 is also welded to the top of the outer wall of the drill rod 5, and the tilt sensor 10 is connected to the control system signal.

[0057] The control system includes a depth unit and a homogenization unit for monitoring homogeneity and controlling and adjusting the degree of agitation.

[0058] The depth unit includes a depth monitoring module, a dip marking module, a dip acquisition module and a depth conversion module.

[0059] The depth monitoring module collects the drilling depth of the drill rod 5 through the depth sensor 9, and transmits the drilling depth to the construction personnel through the external display in real time, thereby improving the control of the construction personnel over the drilling process.

[0060] The inclination angle acquisition module collects the drilling angle of the drill rod 5 during the drilling process through the inclination sensor 10, and transmits the drilling angle to the depth conversion module. The construction personnel set the initial drilling direction. When the drilling direction shifts, the inclination sensor 10 is based on accelerometer and gyroscope technology. When the drill rod 5 tilts, the accelerometer will sense the change in the gravity component. By calculating and processing these data, the inclination sensor 10 can accurately measure the inclination angle of the drill rod 5.

[0061] The inclination marking module marks the node where the inclination occurs, processes the drilling depth collected by the depth monitoring module, records the drilling depth after the inclination starts, and transmits the data to the depth conversion module in real time; in addition, the inclination marking module includes an indicator light, which is fixed to the outside of the frame 3 by bolts. When the drill rod 5 is tilted during drilling (when the inclination collection module detects that an inclination is generated), the inclination marking module sends an electrical signal to drive the indicator light to start and turn red, so that construction personnel can quickly understand the problem of drilling inclination of the drill rod 5 and improve the efficiency of construction personnel in adjusting the drilling of the drill rod 5.

[0062] The depth conversion module is used to convert the relative depth according to the collected inclination angle of the drill rod 5 and the drilling depth after the inclination begins, and calculate the relative depth of the drill rod 5 after the inclination occurs by the following formula:

[0063]

[0064] Where, d x is the relative depth of the drill rod 5 after it is drilled into the inclined position, d g is the drilling depth after tilting, θ is the tilt angle, r z is the radius of the drill rod 5, f(d x ) is a preset attenuation function with d x is the attenuation coefficient obtained for the independent variable.

[0065] Embodiment 2:

[0066] As attached Figure 3 As shown, the difference from Example 1 is that the outer wall of the drill rod 5 is provided with a wear-resistant layer 11, which reduces the friction between the outer wall of the drill rod 5 and the soil and cement slurry during the drilling process, thereby improving the wear resistance of the drill rod 5 and extending its service life.

[0067] Embodiment 3:

[0068] As attached Figure 4 and Figure 5As shown, the difference from Example 2 is that a plurality of variable-angle fins 12 are provided on the circumference of the outer wall of the drill rod 5, and the variable-angle fins 12 include a fixing frame 121 welded to the drill rod 5, and the fixing frame 121 is arranged along the normal direction of the outer wall of the drill rod 5, and a sleeve 122 is welded to the end of the fixing frame 121 away from the drill rod 5, and the end of the sleeve 122 away from the drill rod 5 is rotatably connected with a stirring piece 123 through a bearing, and a driving component for driving the stirring piece 123 to rotate is fixedly connected in the sleeve 122, and the driving component includes a servo motor, and the output shaft of the servo motor is fixedly connected to one end of the stirring piece 123, so that the stirring piece 123 can swing with the fixing frame 121 as the axis. During the drilling process of the drill rod 5, the drill rod 5 will rotate by itself, and the stirring piece 123 will rotate with the As the drill rod 5 rotates about the axis of the drill rod 5, the sprayed cement slurry is stirred. When the servo motor drives the stirring blade 123 to rotate around the fixed frame 121, different angles of the stirring blade 123 will produce different stirring effects on the cement slurry. When the mixing effect of the cement slurry is not good (too thick), the angle between the stirring blade 123 and the vertical plane can be appropriately increased to reduce the stirring effect of mixing the cement slurry and the soil; on the contrary, if the mixing effect is excessive and causes the cement slurry to be stratified or separated (too thin), the angle between the stirring blade 123 and the vertical plane can be appropriately reduced. When the stirring blade 123 is coplanar with the vertical plane, the stirring effect is strongest, and the cement slurry is mixed with more soil. The servo motor is connected to the control system signal to realize intelligent control of the rotation of the servo motor, which is beneficial to improving the stirring efficiency.

[0069] The uniformity unit includes a uniformity monitoring module and an adjustment module.

[0070] The uniformity monitoring module detects the water content of the cement slurry in the slurry transport pipe 6 through the cement sensor 8. Since the standard water content of cement slurries of different strengths is a constant, the difference between the detected water content of the cement slurry and the standard water content is calculated. When the difference is greater than 5%, it is judged that the sprayed cement slurry is too thin. When the difference is less than -5%, it is judged that the sprayed cement slurry is too thick. When the difference is between 5% and -5%, it is judged that the sprayed cement slurry is mixed evenly.

[0071] The adjustment module adjusts the angle of the stirring blade 123 according to the detected uniformity. When the uniformity is judged to be too thin, the control system sends a rotation signal of the driving component to make the stirring blade 123 and the fixed frame 121 collinear. When the uniformity is judged to be too thick, the control system sends a rotation signal of the driving component to make the angle between the stirring blade 123 and the fixed frame 121 45°.

[0072] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
