[0027] When it is necessary to monitor the soft soil layer of a subway vehicle depot, first, a person holds the slide rod 10, then inserts the insertion rod into the ground, and after insertion, moves the base 1 to be in contact with the ground, at this time, the visual camera 11 photographs the scale value between the scale ruler 14 and the inner wall at the bottom of the protective cylinder 2, which is the initial value, when the soft soil layer subsides, the insertion rod will move downward with the soft soil layer, so the scale value between the scale ruler 14 and the inner wall at the bottom of the protective cylinder 2 will also change, the visual camera 11 photographs the change of the scale value in real time, and transmits the image data to the controller 12, which monitors and records the change of the scale value in real time, when the change of the scale value is detected, the controller 12 can be connected to a remote server in advance to upload the scale value data in real time, the remote server monitors the data in real time, and sends a remote alarm message such as a short message when necessary to prompt the person that the soft soil layer has subsided, the battery 9 provides power support for the visual camera 11 and the controller 12 to ensure that the monitoring device can operate stably for a long time.

[0028] The insertion rod includes an insertion rod body 6 and a tapered block 7, the insertion rod body 6 is fixed to the outer wall at the bottom of the slide rod 10 by bolts, and the tapered block 7 is welded to the outer wall at the bottom of the insertion rod body 6;

[0029] The setting of the tapered block 7 can improve the soil breaking ability of the insertion rod body 6, and facilitate the insertion of the insertion rod into the ground.

[0030] The base 1 is welded with a insertion pin 5 at the bottom;

[0031] The setting of the insertion pin 5 can ensure the stability of the base 1 relative to the soft soil layer after it is in contact with the ground.

[0032] Working principle: Before monitoring, the operator first holds the slide rod 10, and uses the insertion rod to insert the device into the ground, the insertion pin 5 at the bottom of the base 1 ensures the stability of the device on the ground to prevent displacement of the device due to movement of the soft soil layer, after installation, the visual camera 11 begins to photograph the scale ruler 14, records the initial scale value, the visual camera 11 continuously photographs the scale value of the scale ruler 14, and transmits the real-time image data to the controller 12, which not only records the current scale value, but also compares it with the initial scale value to evaluate the settlement amount, the controller 12 is connected to the remote server in advance, and can upload the scale value data in real time, the remote server receives the data and monitors and analyzes it in real time, if a significant change in the scale value is detected, i.e., the soft soil layer subsides, the server will trigger an alarm mechanism, the alarm information can be sent to the preset recipient in the form of a short message, prompting them of the soft soil layer subsidence situation so that timely measures can be taken, the battery 9 provides necessary power support for the visual camera 11 and the controller 12 to ensure that the device can operate stably for a long time.

[0033] Example 2

[0034] A monitoring device for construction control in soft soil layers at a subway depot, designed to further improve the stability between base 1 and the soft soil layer, such as... Figures 1 to 5 As shown, this embodiment makes the following additions based on embodiment 1: The inner wall of the rectangular groove opened on the surface of the base 1 is fixed with a guide rod 19 by a pin, and the outer wall of the guide rod 19 is slidably connected with a transverse insert plate 16, and the top of the transverse insert plate 16 is welded with a U-shaped frame 18. The top outer wall of the base 1 is fixed with a T-shaped rod 8 by screws, and the outer wall of the T-shaped rod 8 is slidably connected with a lifting seat 4, and the bottom of the lifting seat 4 is welded with a connecting seat 17. The connecting seat 17 and its corresponding U-shaped frame 18 are rotatably connected by a swing arm 15. The top outer wall of the base 1 is rotatably connected with a threaded column 13, and the threaded column 13 and the lifting seat 4 are threadedly connected.

[0035] To further ensure the relative stability between the base 1 and the soft soil layer, after the pin 5 is inserted into the soft soil layer, the rotating threaded column 13 causes the lifting seat 4 to move vertically downward under the guidance of the T-shaped rod 8. The vertical movement of the lifting seat 4 is converted into the lateral movement of the U-shaped frame 18 and the horizontal insertion plate 16 by the swing arm 15, so that the horizontal insertion plate 16 can slide along the guide rod 19 and finally be inserted horizontally into the soft soil layer, thereby further improving the stability between the base 1 and the soft soil layer in conjunction with the pin 5.
