Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring technology, and in particular to a settlement monitoring device for dewatering construction. Background Technology

[0002] In construction engineering, especially in the excavation of deep foundation pits and the construction of underground projects, dewatering is a common construction measure. Dewatering will cause changes in the pore water pressure of the surrounding soil, which will in turn cause foundation settlement. In order to avoid excessive ground settlement during the dewatering process and serious damage to surrounding buildings, underground pipelines, etc., it is necessary to observe the settlement deformation outside the foundation pit and outside the dewatering well.

[0003] Current technology primarily uses fixed inclinometers for detection. The inclinometer is installed inside a pre-embedded inclinometer tube, and the displacement and settlement of the soil are inferred by measuring changes in the inclination angle of the tube. Furthermore, a detection probe equipped with sensors monitors stress changes within the soil to indirectly understand the settlement status.

[0004] Regarding the aforementioned technologies, during the dewatering construction process, soil disturbance around the probe causes scattered mud and cement slurry to continuously converge towards the probe area. On the one hand, the impact of water flow will push the silted mud at the bottom of the pit towards the probe, causing it to accumulate on the initial adhesion layer. On the other hand, when construction workers are carrying out support work around the probe, the sprayed cement slurry may directly splash onto the probe surface, obstructing the probe and causing sensor signal attenuation or interruption, affecting the stability of the detection device. Utility Model Content

[0005] To improve the stability of the detection device, this application provides a settlement monitoring device for precipitation construction.

[0006] This application provides a settlement monitoring device for dewatering construction, which adopts the following technical solution: A settlement monitoring device for dewatering construction includes a testing platform, a connecting rod at the lower end of the testing platform, a detection probe at the lower end of the connecting rod, a protective cover at the end of the connecting rod near the detection probe, the protective cover being slidably connected to the connecting rod vertically, the detection probe being located inside the protective cover in the initial state, a lifting component at the upper end of the testing platform, the lifting component driving the detection probe to descend and detect the foundation pit during monitoring, and a power supply component at the upper end of the testing platform supplying power to the testing device.

[0007] By adopting the above technical solution, when monitoring the foundation pit, the lifting assembly drives the connecting rod to descend, which in turn drives the detection probe to descend, allowing the detection probe to detect the internal conditions of the foundation pit. The power supply assembly supplies power to the detection device, enabling the equipment to operate for extended periods and reducing the probability of interrupted detection processes and data loss due to power outages. This is especially suitable for foundation pit construction sites in the field without a fixed power source. In the initial state, the probe is located inside the protective cover, which effectively isolates the probe from dust, soil, and construction wastewater at the foundation pit site, reducing the failure rate of the probe due to environmental damage and extending the service life of the equipment. When detection is required, the protective cover slides vertically, at which point the protective cover no longer obstructs the detection probe, allowing the probe to perform detection and improving the stability of the detection device.

[0008] Optionally, the detection probe includes a stratified settlement detector, a water level sensor, and a monitoring probe. The stratified settlement detector is located at the lower end of the connecting rod and is used to monitor the settlement differences of soil at different depths. The water level sensor is located at the lower end of the stratified settlement detector and is used to detect dynamic changes in the groundwater level. The monitoring probe is located at the lower end of the water level sensor and is used to visually record the internal state of the foundation pit.

[0009] By adopting the above technical solutions, the layered settlement detector can penetrate to different depths in the soil. By monitoring the settlement differences of soil at different depths, the settlement pattern of the soil in the vertical direction can be obtained, which helps to adjust the construction plan in a timely manner and reduce the damage to the building structure caused by uneven settlement. The water level sensor can accurately detect the dynamic changes of the groundwater level, promptly detect abnormal changes in the groundwater level, and take corresponding drainage or dewatering measures to ensure the safety of the foundation pit construction. The monitoring probe can visually record the internal state of the foundation pit, enabling engineers to intuitively observe the construction situation, soil deformation, support structure status, etc. in the foundation pit, and promptly detect potential safety hazards.

[0010] Optionally, a lead screw is provided on one side of the connecting rod, a protective cover is located on one side of the lead screw, and the anti-slip cover is threadedly connected to the lead screw. A motor is provided at one end of the lead screw, and the output shaft of the motor is coaxially fixed with the lead screw.

[0011] By adopting the above technical solution, the motor can drive the lead screw to rotate, the connecting rod limits the protective cover, and the rotation of the lead screw drives the protective cover to move vertically, so that the detection probe initially located inside the protective cover can be smoothly lowered to detect the foundation pit. After the detection is completed, the detection probe can be retracted into the protective cover for protection, improving the convenience of using the device.

[0012] Optionally, the lifting assembly includes a second motor, a reduction gearbox, a rotating wheel, a conveyor rope, and a lifting block. The second motor is fixed to the upper end of the testing platform. The reduction gearbox is coaxially fixed with the output shaft of the second motor. The rotating wheel is fixed to one side of the reduction gearbox. The conveyor rope is evenly wound around the surface of the transmission wheel. One end of the conveyor rope is fixed to the lifting block. The connecting rod is located at the lower end of the conveyor rope, and the connecting rod is detachably connected to the lifting block.

[0013] By adopting the above technical solution, motor two is fixed at the end of the testing platform as a power source, providing basic power for the entire lifting process. The reduction gearbox is coaxially fixed with the output shaft of motor two, which can reduce the high-speed rotation of motor two into a low-speed, high-torque rotation suitable for lifting operations, ensuring the stability of power transmission. Through the precise transmission of the reduction gearbox, the rotating wheel can rotate at a predetermined angle and speed. The conveyor rope is evenly wound on the surface of the transmission wheel. As the rotating wheel rotates, the conveyor rope can be orderly wound and unwound, thereby driving the lifting block to achieve lifting movement. The connecting rod is detachable from the lifting block, and connecting rods of different lengths, specifications, or functions can be flexibly replaced according to different testing tasks and site conditions, thereby adjusting the detection depth and range of the detection probe and improving the flexibility of the device.

[0014] Optionally, the lifting block has a groove, the connecting rod is inserted into the groove and engaged with the inner wall of the groove, and a locking rod is provided on one side of the lifting block, which passes through the lifting block and the connecting rod in sequence.

[0015] By adopting the above technical solution, the connecting rod, after being inserted into the groove, can be effectively positioned and constrained in the horizontal direction, reducing horizontal swaying or displacement of the connecting rod during lifting. The locking rod passes through the lifting block and the connecting rod in sequence, playing a crucial role in fixing the connecting rod in the vertical direction. The presence of the locking rod prevents the connecting rod from falling off in the vertical direction, complementing the groove engagement and ensuring a firm connection between the connecting rod and the lifting block from two main directions, thus improving the stability of the monitoring device.

[0016] Optionally, the power supply components include a photovoltaic panel and several wind turbine blades. A support rod is fixed to the upper end of the test platform. The photovoltaic panel is fixed to the upper end of the support rod and is used to collect solar energy. Several wind turbine blades are located at the upper end of the support rod and are rotatably connected to the support rod. When the wind speed in the environment generates airflow, the wind turbine blades rotate.

[0017] By adopting the above technical solution, the photovoltaic panel is fixed to the upper end of the support rod, which can fully collect solar energy and convert it into electrical energy to provide stable power support for the monitoring device. When the wind speed in the environment generates airflow, the wind turbine will rotate and convert wind energy into electrical energy. This power supply method that combines solar and wind energy improves the continuity and reliability of energy supply.

[0018] Optionally, a warning light is provided at the upper end of the testing platform. The warning light contains a buzzer. When the testing probe detects an abnormality, the warning light turns red and the buzzer emits a sharp popping sound.

[0019] By adopting the above technical solution, when the detection probe detects an abnormality, the warning light immediately illuminates red, and its conspicuous color can quickly attract people's attention from a distance and in complex environments. At the same time, the buzzer emits a sharp, piercing sound; the strong sound stimulus can penetrate the noise of the scene and promptly alert relevant personnel, making them quickly aware that a dangerous situation has occurred.

[0020] Optionally, a cleaning brush is provided inside the protective cover. The cleaning brush is in contact with the detection probe. When the protective cover slides, the cleaning brush cleans the dirt on the surface of the detection probe.

[0021] By adopting the above technical solution, the cleaning brush can automatically clean the dirt on the surface of the detection probe during the sliding process of the protective cover, reducing the probability of dirt obstructing the detection probe and improving the detection accuracy of the detection probe.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In the initial state, the probe is located inside the protective cover, which can effectively isolate the dust, soil and construction wastewater at the foundation pit site, reduce the failure rate of the probe caused by environmental damage, and extend the service life of the equipment. When testing is required, the protective cover slides vertically. At this time, the protective cover no longer blocks the detection probe, and the detection probe performs the test, improving the stability of the detection device. 2. The connecting rod and the conveyor rope are detachable, allowing for flexible replacement of connecting rods of different lengths, specifications, or functions according to different testing tasks and site conditions. This adjusts the testing depth and range of the testing probe, improving the flexibility of the device. 3. During the sliding process of the protective cover, the cleaning brush can automatically clean the dirt on the surface of the detection probe, reducing the probability of dirt obstructing the detection probe and improving the accuracy of the detection probe.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses a settlement monitoring device for precipitation construction. Example

[0029] Reference Figure 1 and Figure 2 A settlement monitoring device for precipitation construction includes a detection platform 1. A second motor 111 is fixedly mounted on the upper end of the detection platform 1. A reduction gearbox 112 is fixedly mounted on the output shaft of the second motor 111. When the second motor 111 starts, it drives the reduction gearbox 112 to rotate, reducing the high-speed rotation output of the second motor 111 into low-speed, high-torque rotation, ensuring the stability of power transmission. A transmission wheel 113 is fixedly mounted on one side of the reduction gearbox 112. The rotation of the reduction gearbox 112 drives the transmission wheel 113 to rotate. A conveyor rope 114 is evenly wound on the surface of the transmission wheel 113. With the rotation of the conveyor rope 114, the conveyor rope 114 can be wound and unwound in an orderly manner. A lifting block 115 is fixed at one end of the conveyor rope 114. The winding and unwinding of the conveyor rope 114 causes the lifting block 115 to move vertically. A connecting rod 12 is provided at the end of the lifting block 115 away from the conveyor rope 114. The connecting rod 12 is detachably connected to the lifting block 115. The lifting of the lifting block 115 causes the connecting rod 12 to rise and fall. A detection probe 121 is fixed at the end of the connecting rod 12 away from the lifting block 115. The vertical movement of the connecting rod 12 causes the detection probe 121 to move vertically, so that the detection probe 121 can detect the foundation pit.

[0030] Reference Figure 3 The detection probe 121 includes a stratified settlement detector 1211, a water level sensor 1212, and a monitoring probe 1213. The stratified settlement monitor is located at the lower end of the connecting rod 12. The stratified settlement detector 1211 can penetrate into different depths of the soil. By monitoring the settlement differences of soil at different depths, the settlement pattern of the soil in the vertical direction can be obtained, which helps to adjust the construction plan in a timely manner and reduce the damage to the building structure caused by uneven settlement.

[0031] Reference Figure 3The water level sensor 1212 is located at the lower end of the stratified settlement detector 1211. The water level sensor 1212 can accurately detect the dynamic changes of the groundwater level, promptly detect abnormal changes in the groundwater level, and take corresponding drainage or dewatering measures to ensure the safety of the foundation pit construction. The monitoring probe 1213 is located at the lower end of the water level sensor 1212. The monitoring probe 1213 visually records the internal state of the foundation pit, enabling engineers to intuitively observe the construction situation, soil deformation, support structure status, etc. in the foundation pit, and promptly detect potential safety hazards.

[0032] Reference Figure 2 and Figure 3 The lifting block 115 has a groove 123, into which the connecting rod 12 is inserted and engaged with the inner wall of the groove 123. This provides effective positioning and constraint in the horizontal direction, reducing horizontal swaying or displacement of the connecting rod 12 during lifting. A locking rod 124 is provided on one side of the lifting block 115, passing through both the lifting block 115 and the connecting rod 12. This reduces the possibility of the connecting rod 12 falling off in the vertical direction and complements the engagement with the groove 123. This ensures a secure connection between the connecting rod 12 and the lifting block 115 from two main directions, improving the stability of the monitoring device. Furthermore, connecting rods 12 of different lengths, specifications, or functions can be flexibly replaced according to different detection tasks and site conditions, thereby adjusting the detection depth and range of the detection probe 121 and improving the flexibility of the device.

[0033] Reference Figure 1 The upper part of the testing platform 1 is equipped with a power supply component 13, which includes a photovoltaic panel 131 and several wind turbine rotors 132. A support rod is fixed to the upper part of the testing platform 1, and the photovoltaic panel 131 is fixed to the upper part of the support rod. Under sunlight, the photovoltaic panel 131 can fully collect solar energy and convert it into electrical energy, providing stable power support for the monitoring device. Several wind turbine rotors 132 are located at the upper part of the support rod and are rotatably connected to the support rod. When wind speed generates airflow in the environment, the wind turbine rotors 132 will rotate and convert wind energy into electrical energy. This power supply method that combines solar and wind energy improves the continuity and reliability of energy supply.

[0034] Reference Figure 1 The upper part of the detection platform 1 is equipped with a warning light 14, which contains a buzzer. When the detection probe 121 detects an abnormality, the warning light 14 immediately illuminates red, and its conspicuous color can quickly attract people's attention from a distance and in complex environments. At the same time, the buzzer emits a sharp, piercing sound, and the strong sound stimulation can penetrate the noise of the scene, promptly alerting relevant personnel and making them realize that a dangerous situation has occurred.

[0035] Reference Figure 2 and Figure 3 A protective cover 122 is provided at one end of the connecting rod 12 near the detection probe 121. The protective cover 122 is slidably connected to the connecting rod 12 in a vertical direction. In the initial state, the probe is located inside the protective cover 122, which can effectively isolate the dust, soil and construction wastewater at the foundation pit site, reduce the failure rate of the probe caused by environmental damage, and improve the stability of the detection device.

[0036] Reference Figure 3 The upper end of the connecting rod 12 is equipped with a motor 1221, and a lead screw 1222 is provided on one side of the connecting rod 12. The output shaft of the motor 1221 is coaxially fixed with the lead screw 1222. When the motor 1221 starts, it drives the lead screw 1222 to rotate. The protective cover 122 is located on one side of the lead screw 1222, and the anti-slip cover is threadedly connected to the lead screw 1222. The connecting rod 12 limits the protective cover 122. The rotation of the lead screw 1222 drives the protective cover 122 to move vertically, thereby separating the protective cover 122 from the detection probe 121 and smoothly lowering it to inspect the foundation pit. After the inspection is completed, the detection probe 121 can be retracted into the protective cover 122 for protection, improving the convenience of the device.

[0037] Reference Figure 3 The protective cover 122 is equipped with a cleaning brush 1223, which is attached to the detection probe 121. The surface of the cleaning brush 1223 is provided with several soft and elastic bristles. During the sliding process of the protective cover 122, the cleaning brush 1223 can automatically clean the dirt on the surface of the detection probe 121, reduce the probability of dirt obstructing the detection probe 121, and improve the detection accuracy of the detection probe 121.

[0038] The implementation principle of the settlement monitoring device for dewatering construction in this application embodiment is as follows: During detection, motor 111 starts and drives the rotating wheel 113 to rotate. As the rotating wheel 113 rotates, the conveying rope 114 is released in an orderly manner, thereby driving the connecting rod 12 down into the well. The connecting rod 12 descends, causing the protective cover 122 and the detection probe 121 to descend synchronously. In the initial state, the detection probe 121 is located inside the protective cover 122, which can effectively isolate the dust, soil, and construction wastewater at the foundation pit site, reducing the failure rate of the probe due to environmental damage. When the detection point is reached, the protective cover 122 slides vertically and separates from the detection probe 121 to detect the foundation pit, reducing the probability of dirt obscuring the detection probe 121 and improving the stability of the device.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
