Description

Technical Field

[0001] This utility model relates to the field of automated measurement technology, specifically to a remote automated monitoring device for settlement of engineering pile foundations. Background Technology

[0002] In civil engineering, high-rise buildings, bridges, tunnels, and large-scale infrastructure construction, engineering pile foundations, as critical deep foundation structures, play a vital role in transferring the enormous loads from the superstructure to deep, stable strata. However, during construction loading or long-term operation, pile foundations may settle due to factors such as changes in geological conditions, soil consolidation, construction disturbance, or overloading. Uneven settlement, in particular, can easily lead to serious safety problems such as structural cracking, tilting, or even instability. Therefore, real-time, continuous, and high-precision monitoring of pile foundation settlement has become a core aspect of ensuring project safety. Traditional settlement monitoring largely relies on manual leveling measurements, which suffers from drawbacks such as long cycles, low efficiency, data lag, and the inability to provide real-time early warnings.

[0003] However, the automation level of existing monitoring devices is low, and many operations still require manual completion. This not only increases labor costs but also reduces the real-time nature and accuracy of monitoring. Secondly, the data processing and analysis capabilities of existing devices are limited, making it difficult to achieve real-time analysis and early warning of settlement data, thus affecting timely response to engineering risks. In addition, the installation and maintenance of existing monitoring devices are complex, hindering rapid deployment and long-term stable operation. Utility Model Content

[0019] 1. By setting up a detachable plug-in fixing plate and a clamping and following mechanism, synchronous tracking and monitoring of the settlement of engineering pile foundations can be achieved. The settlement of the pile foundation causes the clamping block and lifting block to move vertically downward, ensuring that the measuring device moves in unison with the pile body. This solves the problems of easy detachment and delayed response of traditional monitoring equipment, and improves data continuity and measurement reliability.

[0020] 2. By adopting a hydraulic linkage amplification structure, the minute settlement displacement is converted into a significant upward movement of the second telescopic column. Combined with the scale and pointer, it enables intuitive on-site readings and drives the displacement sensor to output electrical signals, realizing the combination of local display and remote automated monitoring, taking into account both on-site convenience and the intelligent needs of back-end management.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, the remote automated monitoring device for settlement of engineering pile foundations provided in this embodiment includes: a ground surface 1; an engineering pile foundation 2, which is set on top of the ground surface 1; a plug-in assembly 3, which is set on both sides of the top of the engineering pile foundation 2 on the ground surface 1, including a first fixing plate 31, which is set on one side of the engineering pile foundation 2 on the top of the ground surface 1, and a second fixing plate 32, which is set on the side of the top of the ground surface 1 away from the first fixing plate 31; and a monitoring module 4, which is set in two sets and is located on top of the first fixing plate 31 and the second fixing plate 32, including a support frame 41, which is set on the top of the side of the first fixing plate 31 and the second fixing plate 32 away from the engineering pile foundation 2.

[0032] In this embodiment, the plug-in component 3 and the monitoring module 4 constitute the remote automated monitoring device for settlement of engineering pile foundations involved in this application.

[0033] It should also be noted that the engineering pile foundations in this application can be precast concrete piles, steel pipe piles, bored cast-in-place piles, etc. Figure 1 In this embodiment, a precast concrete pile is used as an example for describing the engineering pile foundation. Of course, other types of engineering pile foundations can also adopt similar structures, which will not be elaborated on later.

[0034] Understandable Figure 1 The diagram only schematically illustrates some of the components included in the monitoring device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, monitoring devices can also include, compared to Figure 1 More or fewer parts.

[0035] It should also be understood that the displacement sensor and data acquisition module were purchased from the market and are common knowledge in this field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0036] In this embodiment, ground 1 provides the installation foundation for the device. The engineering pile foundation 2, the object to be monitored, is a cylindrical reinforced concrete structure with high strength and durability. The plug-in assembly 3 includes a first fixing plate 31 and a second fixing plate 32, made of high-strength aluminum alloy, which has good corrosion resistance and lightweight characteristics, and is used to fix the monitoring module 4. The monitoring module 4 includes a support frame 41, made of high-strength stainless steel, which has good corrosion resistance and stability, and is used to install and support the monitoring equipment. The monitoring module 4 is fixed to both sides of the engineering pile foundation 2 through the plug-in assembly 3, and the monitoring module 4 monitors the settlement of the engineering pile foundation 2 in real time. This realizes remote automated monitoring of the settlement of the engineering pile foundation 2, improving monitoring efficiency and accuracy.

[0037] Example 2:

[0038] Based on Example 1, in order to further improve the stability during monitoring, plug-in components 3 are installed on both sides of the top engineering pile foundation 2 of ground 1.

[0039] Specifically, the plug-in assembly 3 includes: plug blocks 33, disposed on both sides of the first fixing plate 31 near the end of the engineering pile foundation 2; slots 34, opened on both sides of the second fixing plate 32 near the end of the engineering pile foundation 2, with the plug blocks 33 inserted into the slots 34; upper threaded blocks 35, disposed on both sides of the first fixing plate 31 near the end of the engineering pile foundation 2, with threaded holes in the middle; lower threaded blocks 36, disposed on both sides of the second fixing plate 32 near the end of the engineering pile foundation 2, with threaded holes in the middle, and overlapping with the upper threaded blocks 35 vertically; locking bolts 37, two sets, threadedly connected to the threaded holes in the middle of the upper threaded blocks 35 and the lower threaded blocks 36; and locking nuts 38, two sets, located at the bottom of the lower threaded blocks 36, and threadedly connected to the bottom of the locking bolts 37.

[0040] In a preferred embodiment, the insert block 33, with a rectangular structure, is made of high-strength aluminum alloy, exhibiting good wear resistance and stability, and is used to mate with the slot 34 of the second fixing plate 32. The slot 34, also with a rectangular groove, is made of high-strength aluminum alloy, exhibiting good wear resistance and stability, and is used to insert the insert block 33. The upper threaded block 35, with a rectangular structure, is made of high-strength stainless steel, exhibiting good wear resistance and corrosion resistance. The lower threaded block 36, with a rectangular structure, is also made of high-strength stainless steel, exhibiting good wear resistance and corrosion resistance. The locking bolt 37, with a cylindrical structure, is made of high-strength stainless steel, exhibiting good wear resistance and corrosion resistance. The locking nut 38, with an external hexagonal structure, is made of high-strength stainless steel, exhibiting good wear resistance and corrosion resistance. The insert block 33 is inserted into the slot 34, the locking bolt 37 is screwed into the threaded holes of the upper threaded block 35 and the lower threaded block 36, and the locking nut 38 is tightened at the bottom of the locking bolt 37, thus achieving a fixed connection between the first fixing plate 31 and the second fixing plate 32. Ensure a stable connection between the first fixing plate 31 and the second fixing plate 32 to prevent the device from loosening during use.

[0041] Specifically, the monitoring module 4 includes: a fixing component 42, which is disposed on the top of the support frame 41; a hydraulic component 43, which is disposed on the top of the first fixing plate 31 and the second fixing plate 32 on the side near the support frame 41; and a monitoring terminal box 44, which is disposed on the top of the first fixing plate 31.

[0042] In this embodiment, the monitoring terminal box 44 is made of high-strength aluminum alloy, which has good wear resistance and stability, and is used for data acquisition and transmission. The fixing component 42 secures the monitoring equipment, the hydraulic component 43 monitors the settlement of the engineering pile foundation 2, and the monitoring terminal box 44 collects and transmits the monitoring data. This enables real-time monitoring and data transmission of the settlement of the engineering pile foundation 2, improving the automation and remote monitoring capabilities.

[0043] Specifically, the fixing component 42 includes: a lifting block 421 located inside the support frame 41 and sliding up and down; a sliding block 422 disposed on both sides of the lifting block 421 and embedded in the inner walls of both sides of the support frame 41 and sliding; a threaded rod 423 rotatably disposed inside the lifting block 421; a knob 424 rotatably disposed on the side of the lifting block 421 away from the engineering pile foundation 2 and bolted to the threaded rod 423; a clamping block 425 disposed on the side of the lifting block 421 close to the engineering pile foundation 2 and bearing-connected to the end of the threaded rod 423 away from the knob 424; and a telescopic rod 426 disposed on the side of the lifting block 421 close to the clamping block 425 and located on both sides of the threaded rod 423.

[0044] In this configuration, the lifting block 421, a rectangular structure made of high-strength aluminum alloy, offers excellent wear resistance and stability, and is used to adjust the height of the monitoring equipment. The sliding block 422, a T-shaped structure also made of high-strength aluminum alloy, provides excellent wear resistance and stability, ensuring stable movement of the lifting block 421. The threaded rod 423, a cylindrical structure made of high-strength stainless steel, offers excellent wear resistance and corrosion resistance, and is used to push the clamping block 425. A locking nut is provided on one side to lock the horizontal position of 423 on the lifting block 421. The knob 424, a cylindrical structure made of high-strength stainless steel, offers excellent wear resistance and corrosion resistance, and is used for manually operating the threaded rod 423. The clamping block 425, an arc-shaped structure made of high-strength stainless steel, offers excellent wear resistance and corrosion resistance, and is used to clamp the engineering pile foundation 2. A layer of highly elastic, high-friction rubber pad is adhered to the clamping surface of the clamping block 425. The rubber pad provides excellent anti-slip performance and can adapt to the irregular shape of the engineering pile foundation 2 surface, ensuring clamping stability.

[0045] The telescopic rod 426, with its cylindrical structure and high-strength aluminum alloy material, offers excellent wear resistance and stability, serving as an auxiliary guide. Rotating the threaded rod 423 via the knob 424 pushes the clamping block 425 towards the engineering pile foundation 2. The rubber pad of the clamping block 425 maintains close contact with the surface of the engineering pile foundation 2, generating sufficient friction and clamping force to ensure the stability of the engineering pile foundation 2 during monitoring. This ensures that the clamping block 425 firmly holds the engineering pile foundation 2, preventing slippage or displacement during monitoring and improving the accuracy and reliability of the monitoring.

[0046] Example 3:

[0047] Based on Example 2, in order to monitor the settlement of the engineering pile foundation 2, a monitoring module 4 is installed on the top of the first fixing plate 31 and the second fixing plate 32.

[0048] Specifically, the hydraulic assembly 43 includes: a lower pressure plate 431, disposed at the bottom of the lifting block 421 near the engineering pile foundation 2; a first telescopic column 432, disposed at the bottom of the lower pressure plate 431; a first cylinder 433, disposed at the top of the first fixed plate 31 and the second fixed plate 32 near the first telescopic column 432, and the first telescopic column 432 slides up and down inside the first cylinder 433; a hydraulic pipe 434, disposed at the top of the first fixed plate 31 and the second fixed plate 32, and one end of which is connected to the pipe inside the bottom cavity of the first cylinder 433; a second cylinder 435, disposed at the top of the first fixed plate 31 and the second fixed plate 32 away from the first cylinder 433, and the end of the hydraulic pipe 434 away from the first cylinder 433 is connected to the pipe inside the bottom cavity of the second cylinder 435; and a second telescopic column 436, disposed inside the second cylinder 435, and slides up and down.

[0049] The lower pressure plate 431, a rectangular structure made of high-strength aluminum alloy, offers excellent wear resistance and stability, and is used to transmit pressure. The first telescopic column 432, a cylindrical structure made of high-strength stainless steel, offers excellent wear resistance and corrosion resistance, and slides within the first cylinder 433. The first cylinder 433, also a cylindrical structure made of high-strength stainless steel, offers excellent wear resistance and corrosion resistance. The hydraulic pipeline 434, a cylindrical pipe made of high-strength rubber, offers excellent flexibility, pressure resistance, and corrosion resistance, and is used to transmit hydraulic oil. A sealing ring is required at the connection between the hydraulic pipeline 434 and the first cylinder 433 and the second cylinder 435 to ensure no hydraulic oil leakage. The sealing ring is made of oil-resistant rubber, effectively preventing hydraulic oil leakage and ensuring the sealing performance of the hydraulic system.

[0050] The second cylinder 435, a cylindrical structure, is made of high-strength stainless steel, offering excellent wear and corrosion resistance. The second telescopic column 436, also a cylindrical structure made of high-strength stainless steel, exhibits good wear and corrosion resistance and is used to indicate settlement. Hydraulic pipe 434 transmits hydraulic oil. When settlement occurs in the engineering pile foundation 2, the first telescopic column 432 slides within the first cylinder 433, pushing hydraulic oil through hydraulic pipe 434 into the second cylinder 435, which in turn pushes the second telescopic column 436 upwards, thus indicating the settlement. Sealing rings are installed at the contact points between the first telescopic column 432 and the first cylinder 433, and between the second telescopic column 436 and the second cylinder 435, ensuring no hydraulic oil leakage. The connection via hydraulic pipe 434 ensures the integrity and functionality of the hydraulic system, guaranteeing the accuracy and reliability of settlement monitoring. Simultaneously, the sealing rings effectively prevent hydraulic oil leakage, improving the system's safety and stability.

[0051] In actual use, firstly, the engineering pile foundation 2 is connected to the ground 1. The user places the first fixing plate 31 and the second fixing plate 32 on both sides of the engineering pile foundation 2, aligning the middle hole with the engineering pile foundation 2. Then, the insert block 33 is inserted into the slot 34. The threaded blocks 35 on both sides of the first fixing plate 31 and the second fixing plate 32 are aligned with the middle threaded holes of the lower threaded blocks 36. Next, the user screws the locking bolt 37 into the threaded hole and then tightens the locking nut 38 at the bottom of the locking bolt 37 to lock it. After that, the user inserts the ground nails at the bottom of the first fixing plate 31 and the second fixing plate 32 into the ground 1 and adjusts the first fixing plate 31 and the second fixing plate 32 to be level with the help of a level. Next, the user slides the lifting block 421 upwards to the highest point inside the support frame 41, rotates the knob 424, causing the threaded rod 423 to rotate on the lifting block 421 and push the clamping block 425 towards the engineering pile foundation 2. At the same time, the auxiliary rod inside the telescopic rod 426 extends and guides until one side of the two sets of clamping blocks 425 clamps the outer wall of the engineering pile foundation 2. Then, the pile driver begins to apply pressure to the top of the engineering pile foundation 2. After the engineering pile foundation 2 settles towards the ground 1, it will cause the clamping block 425 and the lifting block 421 to move downwards. At the same time, the lower pressure plate 431 at the bottom of the lifting block 421 will also move along with it. The lower pressure plate 431 will also cause the first telescopic column 432 to move downwards inside the first cylinder 433, and push the oil inside the first cylinder 433 into the hydraulic pipe 434. The hydraulic fluid enters the bottom cavity of the second cylinder 435 through the hydraulic pipe 434. Then, the hydraulic fluid pushes the second telescopic column 436 to slide upward. The pointer on the top of the second telescopic column 436 points to the scale line. Then, a displacement sensor (not shown in the figure) is set on one side of the second cylinder 435 to monitor the movement of the second telescopic column 436. The displacement sensor outputs analog or digital signals, which are collected periodically by the data acquisition module (not shown in the figure) inside the monitoring terminal box 44 and converted into digital data. Then, the processed data is uploaded to the cloud platform wirelessly or wiredly. The cloud server receives the data from each monitoring point, performs trend analysis, rate calculation, and cumulative statistics on the settlement data, determines whether it exceeds the preset threshold, and displays the monitoring data in the form of charts, maps, and reports.

[0052] A displacement sensor is installed on one side of the second cylinder 435. The sensor is electrically connected to the controller. The controller, as the central hub of the entire system, is responsible for receiving instructions, monitoring the status, and controlling the actions of each actuator. By pre-setting a program or adjusting parameters in real time, the settlement control of the engineering pile foundation 2 can be realized. The displacement sensor monitors the height of the second telescopic column 436 in real time and transmits the sensed signal to the controller. The controller controls the operation of the data acquisition module.

[0053] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
