[0025] See Figure 1 , Figure 2 and Figure 3As shown, this application proposes an intelligent monitoring device for foundation pit excavation in complex environments, which further includes: a monitoring terminal 33, which is installed on the ground 1; a support rod, on which the monitoring terminal 33 is installed; a foundation pile 35, which is inserted into the ground 1, and the support rod is installed at the end of the foundation pile 35; a first inclinometer tube 353, in which a hollow through hole 355 is provided in the foundation pile 35, and the first inclinometer tube 353 is located in the hollow through hole 355; and a wiring hole 38, in which the support rod is provided, and the first inclinometer tube 353 is communicatively connected to the monitoring terminal 33.

[0026] Among them, the monitoring terminal 33 is an information aggregation port of an intelligent monitoring device for foundation pit excavation in a complex environment. All monitoring data generated during foundation pit excavation will eventually be collected at the monitoring terminal 33 and displayed on the monitoring terminal 33. The monitoring terminal 33 will also monitor whether any data is abnormal. When any data is abnormal, the monitoring terminal 33 will issue an alarm signal.

[0027] The support rod is used to install the monitoring terminal 33. The support rod includes a rod body 32 and a base 34. The rod body 32 is welded to the base 34, and the base 34 is connected to the end of the foundation pile 35 by fasteners, thereby completing the stable fixation of the monitoring terminal 33.

[0028] In this embodiment, a support plate 37 is also connected to the rod 32, and the monitoring terminal 33 is mounted on the support plate 37 to improve the stability of the monitoring terminal 33. The rod 32 and the support plate 37 are connected by fasteners, or the support plate 37 is installed on the rod 32 by welding.

[0029] The foundation pile 35 is prefabricated in the factory. The foundation pile 35 includes a concrete pile body 351 with a variable diameter and an internal steel reinforcement cage. The steel reinforcement cage includes main bars and stirrups. The main bars have prestress. The two ends of the foundation pile 35 are provided with end plates 352 to connect the main bars. The foundation pile 35 is connected to the base 34 through the end plates 352 and screws. Of course, the base 34 can also be set to the end plates 352 of the foundation pile 35 by welding. No specific limitation is made here.

[0030] The first inclinometer tube 353 is equipped with an inclinometer. The inclinometer tube 353 and the inclinometer are used to measure the horizontal displacement of the foundation pile 35, thereby assessing the stability of the foundation pile 35. The data measured by the inclinometer is transmitted to the monitoring terminal 33 via a data cable. When the stability of the foundation pile 35 is compromised, the monitoring terminal 33 will issue a corresponding warning signal to remind relevant personnel to take remedial action, thus improving the reliability of the monitoring terminal 33 and consequently enhancing the reliability of the intelligent monitoring device for foundation pit excavation in complex environments. A wiring hole 38 is used for wiring, facilitating the rapid transmission of data from the inclinometer in the first inclinometer tube 353 to the monitoring terminal 33.

[0031] Specifically, during the installation of the monitoring terminal 33, the foundation pile 35 is first driven into the ground 1, and the first inclinometer tube 353 is installed inside the foundation pile 35. Then, the support rod is installed on the foundation pile 35, and the connection between the monitoring terminal 33 and the foundation pile 35 is established. Finally, the monitoring terminal 33 is installed on the support rod. By using a foundation pile 35 with a variable diameter, the seismic resistance and deformation capacity of the foundation pile 35 are improved, thereby enhancing the stability of the monitoring terminal 33. The horizontal displacement of the foundation pile 35 is measured through the first inclinometer tube 353 and its internal inclinometer, thus assessing the stability of the foundation pile 35. When the stability of the foundation pile 35 is low, the monitoring terminal 33 will issue a corresponding warning signal to remind relevant personnel to improve the reliability of the monitoring terminal 33.

[0032] See Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the system further includes: a pile tip 36, which is disposed at the bottom of the foundation pile 35; and a support member 354, which is disposed on the inner side of the hollow through hole 355 and has a limiting hole for the first inclinometer tube 353 to pass through. The pile tip 36 is fixed to the end plate 352 at the bottom of the foundation pile 35 by welding or screw connection. The pile tip 36 facilitates the driving of the foundation pile 35 into the ground 1 and reduces the difficulty of driving the foundation pile 35. The support member 354 is used to fix the first inclinometer tube 353, which is inserted into the limiting hole of the support member 354 after the first inclinometer tube 353 is assembled.

[0033] In this embodiment, the support member 354 includes an arc-shaped portion and connecting portions located on both sides of the arc-shaped portion. The connecting portions are bonded to the inner surface of the hollow through hole 355. The limiting hole of the arc-shaped portion is used to limit the planar direction of the first inclinometer tube 353, and the stake tip 36 is used to limit the vertical position of the first inclinometer tube 353, thereby fixing the first inclinometer tube 353.

[0034] See Figure 2 and Figure 4 As shown, in some embodiments, a solar panel 31 is also included, which is disposed on the support rod. The solar panel 31 is used to absorb sunlight and convert it into electrical energy to power the monitoring terminal.

[0035] See Figure 2 and Figure 4As shown, in some embodiments, the system further includes: a back plate 310, which is disposed on the solar panel 31 and rotatably mounted on a support rod; a bracket is provided on the solar panel 31, which is connected to the back plate 310; and reinforcing ribs 39 are also provided on the bracket; an adjustment drive 312, which is rotatably mounted on the support rod; the adjustment drive 312 is an electric cylinder; and an output rod 311 is disposed on the adjustment drive 312 and rotatably connected to the back plate 310. The electric cylinder drives the output rod 311 to perform linear motion through the movement of a ball screw, thereby changing the angle of the solar panel 31. When the direction of illumination changes, the angle of the solar panel 31 can change accordingly, increasing the efficiency of the solar panel 31 in absorbing sunlight.

[0036] In this embodiment, the angle of the solar panel 31 can be adjusted regularly according to the local solar calendar and time to follow the changing direction of sunlight. Alternatively, a light sensor can be installed on the solar panel 31. Using an omnidirectional light sensor, the light intensity at different angles can be compared, and the signal can be transmitted to a monitoring terminal. The monitoring terminal then issues a corresponding command signal, which adjusts the drive 312 to adjust the solar panel 31 to the angle with the strongest light intensity.

[0037] See Figure 1 As shown, in some embodiments, it further includes: a ground settlement measuring instrument 1, which is spaced apart on ground 1 and is communicatively connected to a monitoring terminal 33; the ground settlement measuring instrument 1 is specifically a level or leveling rod, and its lateral arrangement is shown in the figure, while its longitudinal arrangement is one section every 10m. The warning value of the ground settlement measuring instrument 1 is 25mm, and its control value is 30mm. A second inclinometer tube 8 is installed inside the retaining piles 6 of the foundation pit cushion layer 9, and is communicatively connected to the monitoring terminal 33. An inclinometer is also installed inside the second inclinometer tube 8, with a warning value of 0.20% of the excavation depth and a control value of 0.25% of the excavation depth. It also includes: axial force gauges 5; steel pipe cross braces 4 are installed between two spaced retaining piles 6; axial force gauges 5 are installed between the steel pipe cross braces 4 and the retaining piles 6; axial force gauges 5 are communicatively connected to monitoring terminal 33; the lateral arrangement of axial force gauges 5 is shown in the figure; the longitudinal arrangement of axial force gauges 5 is one cross section every five steel pipe cross braces 4; the warning value of axial force gauges 5 is 1900kN; the control value of axial force gauges 5 is 2375kN. Water level observation holes 7 are installed at intervals on the ground 1. Water level gauges are installed in the water level observation holes 7; the water level gauges are communicatively connected to monitoring terminal 33. All the above data are transmitted to monitoring terminal 33 for monitoring to ensure the normal progress of the foundation pit excavation process.
