Description
Technical Field
[0001] The utility model relates to the technical field of pile column monitoring, in particular to a cement mixing pile monitoring device. Background Technique
[0002] The cement mixing pile is an effective form of soft foundation treatment. It uses cement as the main curing agent, and uses a mixing pile machine to spray cement into the soil and fully mix it, so that a series of physical and chemical reactions occur between the cement and the soil, making the soft soil harden and improving the foundation strength. After the construction of the cement mixing pile, it is necessary to monitor the bearing capacity of the pile column to ensure that the strength of the cast cement mixing pile meets the requirements.
[0003] In the prior art, when monitoring the bearing capacity of pile columns, holes are mostly dug around the pile columns to be measured. A jack is placed on the surface of the pile column, a cross beam is placed on the surface of the jack, and a platform is built on the cross beam by stacking cement blocks. Both ends of the platform are supported on the ground to improve stability. Then, cement blocks or other objects are stacked on the surface of the platform to increase the weight and monitor the bearing capacity.
[0004] However, in the actual use process, the objects such as jacks, cross beams, and platforms are simply stacked together. Although they are convenient to disassemble and store, the actual monitoring process is mostly carried out outdoors in the wild, and there are many accidental collisions. There is a risk of collapse and injury to people for objects such as jacks, cross beams, platforms, and the counterweight blocks stacked on the platforms, and the safety performance needs to be improved. Content of the Utility Model
[0005] In order to improve the safety performance, the present application provides a cement mixing pile monitoring device.
[0006] The cement mixing pile monitoring device provided by the present application adopts the following technical solution:
[0007] A cement mixing pile monitoring device includes a hydraulic cylinder and a fixed platform. The piston rod of the hydraulic cylinder is connected to the fixed platform. The fixed platform is provided with a plurality of support columns. The hydraulic cylinder is provided with a fixing plate. The fixing plate is provided with a pressure sensor for measuring pressure. The fixed platform is provided with a surrounding baffle. The fixing plate is provided with a measuring component for measuring the moving distance of the fixing plate.
[0008] By adopting the above technical solution, when monitoring, it is necessary to excavate a monitoring pit near the pile column. During use, the fixed plate at the bottom of the hydraulic cylinder is placed on the surface of the pile column. At the same time, the height of the fixed platform is adjusted by the hydraulic cylinder, and the support columns of the fixed platform are supported on the ground, thus completing the support installation. At this time, the configuration parts are stacked inside the retaining plate of the fixed platform by hoisting, so as to simulate the load on the pile column. During the process of adding counterweights, the pressure sensor can measure the pressure borne by the pile column. At the same time, the moving distance of the fixed plate is measured by the measuring component, so as to obtain the sinking distance of the pile column itself, and then obtain the bearing settlement curve, so as to monitor the bearing capacity of the pile column. Compared with the measurement structure composed of pushing and stacking in the prior art, the overall stability is improved by fixing the hydraulic cylinder and the fixed platform. At the same time, by setting the retaining plate, the possibility of the stacked configuration parts collapsing and sliding down and injuring people is reduced, thus improving the safety performance.
[0009] Preferably, the measuring component includes a measuring rod and a distance sensor. The distance sensor is arranged on the measuring rod, and the measuring rod is slidably arranged on the fixed plate. The distance sensor is used to measure the distance between the distance sensor and the fixed plate.
[0010] By adopting the above technical solution, the bottom of the measuring rod is supported on the bottom of the excavated measuring pit. During the measurement process, when the pile column sinks, the fixed plate follows the sinking under the action of gravity, while the bottom of the measuring rod is resisted, so the measuring rod and the fixed plate slide relative to each other. The distance between the distance sensor and the fixed plate is measured by the distance sensor, and the sinking distance of the pile column can be obtained through the data change of the distance sensor. The operation is simple and convenient, and it is convenient to use.
[0011] Preferably, the measuring rod is provided with a support plate.
[0012] By adopting the above technical solution, the stability of the measuring rod when the measuring rod and the fixed plate slide relative to each other is improved through the support plate, and the possibility that the measuring rod is skewed and affects the measurement result of the distance sensor is reduced, thus improving the measurement accuracy.
[0013] Preferably, it further includes a controller and a display connected by signals. The display is used to display data. The controller is connected to the pressure sensor and the distance sensor by signals. The controller is used to control the display to display the measurement data of the pressure sensor and the distance sensor.
[0014] By adopting the above technical solution, the measurement results of the pressure sensor and the distance sensor are received by the controller, and the display is controlled to display the measurement results in time, which is convenient for intuitive monitoring and improves the timeliness of monitoring.
[0015] Preferably, the display is a display screen, and the display screen is arranged on the retaining plate.
[0016] By adopting the above technical solution, through the display screen arranged on the baffle, the measurement situation can be reflected in time at the monitoring site, which can improve the monitoring timeliness on the one hand, and is convenient for debugging during the installation process, thus improving the measurement accuracy.
[0017] Preferably, the fixed plate is provided with an acoustic wave detection device signal-connected to the controller. The acoustic wave detection device is used to detect acoustic waves, and the controller is used to control the display member to display the detection data of the acoustic wave detection device.
[0018] By adopting the above technical solution, an acoustic wave detection device is arranged on the fixed plate. When the pile column is knocked during monitoring, the acoustic wave detection device will detect data such as the amplitude and vibration frequency of the acoustic wave inside the pile column and send them to the controller, which is then displayed through the display member. The staff can draw an acoustic wave curve according to the detection result. By comparing it with the acoustic wave curve of a normal pile column, it can be judged whether the pile column itself is complete or there is a missing part inside, so as to conduct a missing detection on the pile column and improve the monitoring function.
[0019] Preferably, the fixed plate is rotatably provided with a rotating rod, and the measuring rod is provided with a rotating motor signal-connected to the controller. The rotating motor is used to drive the rotating rod to rotate.
[0020] By adopting the above technical solution, the rotating motor is started by the controller to drive the rotating rod to rotate and knock the pile column, so as to conduct a missing detection, improve the automation, simplify the operation, and improve the convenience of use and monitoring.
[0021] Preferably, the support column is provided with a lifting cylinder, and a lifting plate is arranged on the piston rod of the lifting cylinder.
[0022] By adopting the above technical solution, the distance between the fixed platform and the ground can be adjusted through the lifting cylinder, which is convenient for the installation of the fixed platform and improves the convenience of use. At the same time, by setting the lifting cylinder, the support range of the fixed platform is increased, and monitoring can be carried out even without excavating a measurement pit, thus improving the applicability.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. By setting a hydraulic cylinder, a fixed platform, support columns, a fixed plate, a pressure sensor, a measuring component, and a baffle, when installing, place the fixed plate on the pile column to be monitored. By adjusting the hydraulic cylinder, the support columns of the fixed platform can be supported on the ground. At this time, counterweight objects can be placed inside the baffle of the fixed platform to simulate the load. During this process, the pressure data measured by the pressure sensor can be used to calculate the gravity borne by the pile column. At the same time, by measuring the moving distance of the fixed plate with the measuring component, the sinking distance of the pile column can be calculated, thus completing the monitoring of the pile column. Compared with the prior art, the fixed plate, the hydraulic cylinder, and the fixed platform are interconnected. At the same time, by setting the baffle, the possibility of the counterweight sliding and collapsing is reduced, and the risk of the staff being injured by the collapsing objects is reduced, improving the safety performance;
[0025] 2. By setting a measuring rod, a distance sensor, and a support plate, the measuring rod is supported on the bottom of the excavation measuring pit through the support plate. When the pile column sinks, the fixed plate follows and descends, while the measuring rod cannot descend, and relative sliding occurs between the measuring rod and the fixed plate. The distance sensor measures the distance between the distance sensor and the fixed plate. The sinking distance of the pile column can be obtained through the change of the data of the distance sensor, and the measurement is simple and convenient;
[0026] 3. By setting a controller, an acoustic wave detection device, and a display screen, the acoustic wave detection device is used to measure the acoustic wave changes inside the pile column after knocking and record data such as the amplitude and vibration frequency of the acoustic wave, so as to facilitate the staff to judge whether there are missing parts in the pile column. At the same time, the controller is used to receive the distance sensor, the pressure sensor, and the acoustic wave detection device, and control the display screen to display the measurement data, thus improving the immediacy of the monitoring and the convenience of use.

A pressure sensor 41 is adaptively and fixedly provided in the first measurement groove 31, and the bottom wall of the pressure sensor 41 is flush with the bottom wall of the fixed plate 3. The fixed plate 3 is provided with multiple measurement assemblies 5 for measuring the moving distance. The bottom wall of the fixed platform 2 is fixedly provided with several support columns 21, and the support columns 21 surround the hydraulic cylinder 1 in the middle. A cylinder groove 211 is provided at the bottom wall of the support column 21. A lifting cylinder 212 is fixedly provided in the cylinder groove 211. A lifting plate 213 is fixedly provided on the piston rod of the lifting cylinder 212, and the lifting plate 213 is provided outside the cylinder groove 211. The top wall of the fixed platform 2 is fixedly provided with several enclosure boards 22, and the enclosure boards 22 are fixedly connected in sequence. During use, the fixed plate 3 is placed on the pile column, and through the adjustment of the hydraulic rod and the lifting cylinder 212, the lifting plate 213 is made to abut against the ground. Then, weights are added inside the enclosure boards 22 of the fixed platform 2. The pressure exerted on the pile column can be obtained through the data of the pressure sensor 41. At the same time, the descending distance of the fixed plate 3 is measured through the measurement assembly 5, so as to obtain the settlement depth of the pile column, thereby realizing the monitoring of the pile column. Moreover, all components are fixedly connected, and the enclosure boards 22 enclose the weights, reducing the risk of collapse and injury and improving the safety performance.
[0033] For the convenience of distance monitoring, referring to Figures 1 to 2, the measuring assembly 5 includes a measuring rod 51 and a distance sensor 52. Sliding grooves 33 are provided on the side walls around the fixed plate 3, and the measuring rod 51 is slidably arranged in the sliding grooves 33 in a matching manner. A support plate 511 is fixedly arranged at one end of the measuring rod 51 away from the fixed plate 3. The distance sensor 52 is fixedly arranged on the side wall of the measuring rod away from the fixed plate 3. The distance sensor 52 is arranged below the fixed plate 3 and is used to measure the distance between the distance sensor 52 and the fixed plate 3. The measuring rod 51 abuts against the bottom of the pit through the support plate 511. When the pile column descends, the measuring rod 51 remains stationary while the fixed plate 3 descends, so as to obtain the descending distance of the pile column through the change of the data of the distance sensor 52, improving the convenience of distance monitoring.
[0034] To increase the monitoring function, refer to Figures 1 to 2 , a second measuring groove 32 is provided on the bottom wall of the fixed plate 3. An acoustic wave detection device 42 is fixedly arranged in the second measuring groove 32, and the bottom wall of the acoustic wave detection device 42 is flush with the bottom wall of the fixed plate 3.

At the same time, the controller 4 is also used to control the display screen 221 to display the measurement data of the pressure sensor 41, the distance sensor 52, and the acoustic wave detection device 42. By setting up the control system, while facilitating the control of devices such as the hydraulic cylinder 1, the lifting cylinder 212, and the rotating motor 61, the measurement results of measuring devices such as the pressure sensor 41, the distance sensor 52, and the acoustic wave detection device 42 are timely displayed through the display screen 221, facilitating on-site personnel to debug and monitor, and improving the convenience of use.
[0036] The implementation principle of a cement mixing pile monitoring device in an embodiment of the present application is as follows: The fixing plate 3 is placed on the surface of the pile column.
