Description

Technical Field

[0001] This utility model relates to the field of subway construction monitoring technology, specifically to a surface settlement monitoring device for subway construction lines. Background Technology

[0002] During the construction of urban subways, regardless of whether open-cut, shallow-buried tunneling, or shield tunneling is used, it is necessary to conduct settlement and deformation monitoring of the surrounding environment, such as the ground surface and buildings, within the affected area.

[0003] Chinese utility model patent CN221445119U discloses a monitoring device for automatically detecting ground settlement around a foundation pit. This device vertically fixes the support pole of a measuring plate within the ground surface surrounding the pit. The measuring plate and a reference plate are connected by a telescopic rod. The extension of the telescopic rod allows the support pole of the reference plate to be vertically fixed within the ground layer outside the construction area. A camera then transmits the changes in the scale lines on the measuring plate to a monitoring screen via a signal line for processing. The screen automatically calculates the settlement value and displays it, thus acquiring settlement data outside the construction area. However, this device relies on electronic sensors for distance measurement. Electronic equipment is susceptible to interference from dust, moisture, and vibration, resulting in a high failure rate. Furthermore, it cannot operate stably during power outages, significantly limiting the device's applicability. Utility Model Content

[0004] The purpose of this invention is to provide a surface settlement monitoring device for subway construction lines. This device does not rely on electronic sensors for distance measurement and has a low failure rate.

[0005] The technical solution adopted by this utility model is a surface settlement monitoring device for subway construction lines, including a pole and a settlement pipe sleeved on the outer wall of the pole. An installation ring is fixedly sleeved on the outer wall of the settlement pipe, and a groove is opened on the upper surface of the installation ring. A monitoring rod is hinged to the top of the pole, and a transmission rod parallel to the pole is hinged to the middle of the monitoring rod. The end of the transmission rod away from the monitoring rod is engaged in the groove. A positioning pen is fixed to the end of the monitoring rod away from the pole. A rectangular mounting frame is fixed to the side wall of the pole, and a display board is embedded in the mounting frame. The display board is close to the tip of the positioning pen.

[0006] The features of this utility model also include:

[0007] The slide is radially opened along the mounting ring, and its longitudinal section is trapezoidal. The end of the transmission rod away from the monitoring rod is an inverted trapezoid that matches the slide.

[0008] Anchor bolts run through the mounting ring.

[0009] A fixing sleeve is provided on the outer wall of the end of the pole, and the mounting frame is fixed to the outer wall of the fixing sleeve.

[0010] The top and bottom edges of the mounting frame are mounting grooves, and the display panel is slidably installed within these grooves.

[0011] A protective plate perpendicular to the top of the mounting frame is fixed.

[0012] A handle is fixed to the end of the display board away from the upright.

[0013] The end side wall of the upright has a groove.

[0014] Multiple annular grooves are cut into the outer wall of the settling pipe.

[0015] A spring rod perpendicular to the outer wall of the upright is fixed, and a spring is sleeved on the outer wall of the spring rod. A slider is fixed at the end of the spring rod away from the upright. A guide groove adapted to the slider is opened on the side of the transmission rod opposite to the upright. The spring rod is located between the settling pipe and the monitoring rod.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model uses a mechanical transmission structure, such as a settlement pipe, upright pole, transmission rod, monitoring rod, and positioning pen, to convert the surface settlement into a change in the position of the positioning pen on the display board when the ground settles. This enables intuitive monitoring of the surface settlement. The device does not use electronic sensors for distance measurement, so changes in the external environment have little impact on its measurement and a low failure rate.

[0018] 2. This utility model allows the display board to slide horizontally on the mounting frame by setting an installation groove. When the positioning pen rotates to the scale side due to ground subsidence, the display board can be moved by the handle to bring the scale closer to the tip of the positioning pen for easy observation.

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] A surface settlement monitoring device for subway construction lines, such as Figure 1 As shown, it includes a vertical pole 2 and a settling pipe 3. The settling pipe 3 is a hollow tube. The diameter of the vertical pole 2 is smaller than that of the settling pipe 3, and it is axially fitted inside the settling pipe 3, as shown. Figure 2 As shown, an installation ring 4 is fixedly fitted on the outer surface of the settlement pipe 3. Several anchor bolts 9 are evenly inserted through the installation ring 4. A sliding groove 10 is also provided on the upper surface of the installation ring 4. The sliding groove 10 is arranged radially along the installation ring 4.

[0028] like Figure 3 As shown, a monitoring rod 11 is hinged to the top of the upright 2, and a transmission rod 5 is hinged to the middle of the monitoring rod 11. The transmission rod 5 is parallel to the upright 2, and its end away from the monitoring rod 11 is engaged in the slide groove 10.

[0029] A positioning pen 17 is fixed to the end of the monitoring pole 11 away from the pole 2. A rectangular mounting frame 7 is fixedly installed on the side wall of the pole 2. A display board 14 is embedded in the mounting frame 7. The tip of the positioning pen 17 is perpendicular to and in close contact with the display board 14.

[0030] In use, the bottom end of the upright pole 2 is drilled vertically into the deep underground layer, and the anchor bolt 9 is inserted into the concrete layer 1 and threadedly connected to the concrete layer 1. The mounting ring 4 and the settlement pipe 3 are tightly fixed to the concrete layer 1. At this time, the monitoring pole 11 is kept perpendicular to the upright pole 2. When the ground settles, the position of the upright pole 2 remains unchanged, while the concrete layer 1 will sink along with the ground surface, which will cause the settlement pipe 3 and the mounting ring 4 to sink. The settlement pipe 3 and the mounting ring 4 will have a downward relative displacement relative to the upright pole 2. When the mounting ring 4 sinks, the transmission rod 5 sinks along with it. The sinking of the transmission rod 5 will cause the monitoring pole 11 to rotate about the hinge point with the upright pole 2 as the axis, which will cause the positioning pen 17 at the other end of the monitoring pole 11 to draw an arc on the display board 14. By observing the position change of the positioning pen 17 on the display board 14, the ground settlement can be monitored intuitively.

[0031] During the sinking process, the hinge point between the transmission rod 5 and the monitoring rod 11 will move in an arc-shaped trajectory. In order to keep the transmission rod 5 parallel to the upright rod 2 while sinking, the bottom of the transmission rod 5 will move horizontally within the slide groove 10.

The longitudinal section of the sliding groove 10 is trapezoidal, as shown... Figure 4 As shown, the end of the transmission rod 5 that is engaged in the slide groove 10 is an inverted trapezoid that is adapted to it.

[0040] like Figure 3As shown, a monitoring rod 11 is hinged to the top of the upright 2, and a transmission rod 5 is hinged to the middle of the monitoring rod 11. The transmission rod 5 is parallel to the upright 2, and its end away from the monitoring rod 11 is engaged in the slide groove 10.

[0041] A positioning pen 17 is fixed to the end of the monitoring pole 11 away from the pole 2. A rectangular mounting frame 7 is fixedly installed on the side wall of the pole 2. A display board 14 is embedded in the mounting frame 7. The tip of the positioning pen 17 is perpendicular to and in close contact with the display board 14.
