Description

Technical Field

[0001] The invention relates to the technical field of foundation pit settlement monitoring, in particular to a foundation pit settlement monitoring device. Background Art

[0002] With the development of industrial and civil construction, various complex and large-scale engineering buildings are increasing day by day. The construction of engineering buildings has changed the original state of the ground and exerted a certain pressure on the foundation of the building, which will inevitably cause deformation of the foundation and surrounding strata. Therefore, foundation pit settlement monitoring is an important part of foundation pit construction. It refers to monitoring the settlement of the side walls, bottom walls or surrounding rock formations and soil of the foundation pit during the excavation of the foundation pit and the construction of underground engineering, and timely feedback of the monitoring results to predict the deformation and stable state development caused by further construction. It is an important basis for ensuring the progress of foundation pit construction.

The foundation pit settlement monitoring device can drive the cone tube to insert into the soil under the detection hole through the set driving device, further increasing the tightness between the sinking tube and the soil, and the cone tube can drive the bottom folding plate to rotate through the linkage device while moving downward, and the bottom folding plate rotates while driving the folding plate adjacent to it through the steel cable, that is, the staff only needs to use the driving device to realize multiple actions at the same time, and fix the support tube through multiple insertion rods. However, when the foundation pit settles, the settlement area will be larger, and the placed monitoring device will not be in the settlement center. When the above-mentioned settlement monitoring device is in use, it can only detect the settlement in a small area.

When in use, when the fixed cylinder 11 is tilted, the conducting ball 54 slides inside the horizontal box 50. Since the bottom end of the horizontal box 50 is arc-shaped, when the fixed cylinder 11 is slightly tilted, the conducting ball 54 does not contact the first conducting ring 52. When the fixed cylinder 11 is tilted more, the conducting ball 54 is in close contact with the second conducting ring 53. At the same time, the conducting ball 54 is in close contact with the second conducting ring 53, so that the controller 55 is turned on, and the controller 55 is electrically connected to the external control component, thereby reminding the staff.

The sliding plate 33 is fixed so that the first auxiliary plate 30 and the second auxiliary plate 37 can assist in fixing the insertion rod 29 to reduce the tilting of the insertion rod 29 during operation. Then, the turntable 22 is rotated, and the turntable 22 drives the fixed shaft to rotate.

The installation shaft 18 drives a number of active gears 17 to rotate, and each active gear 17 is meshed with a number of driven gears 16, so that the driven gear 16 drives the corresponding extension plate 15 to rotate, so that the extension plate 15 is unfolded, so that one end of the extension plate 15 is in close contact with the inner wall of the tunnel, and then the soil is backfilled, and the two adjacent fixed cylinders 11 are connected through the installation rod 45; When the ground settles, but the fixed cylinder 11 does not tilt or settle, the soil will drive the sedimentation cylinder 12 to move through the extension plate 15, and the sedimentation cylinder 12 drives the first piston plate 13 to slide inside the fixed cylinder 11 through the connecting frame, so that the flowing liquid inside the fixed cylinder 11 is transported to the first connecting box 23. Since the cross-sectional area of ​​the fixed cylinder 11 is several times larger than the cross-sectional area of ​​the first connecting box 23, the purpose of expanding the moving stroke of the second piston plate 24 is achieved. When the sedimentation cylinder 12 follows the soil to descend to the set standard limit distance, the second piston plate 24 drives the trigger frame 26 to move, so that the trigger frame 26 squeezes the first trigger 27, and the first trigger 27 is electrically connected to the external control component, so as to remind the staff; When a fixed cylinder 11 and a settling cylinder 12 are at the edge of soil settlement, causing the fixed cylinder 11 and the settling cylinder 12 to tilt, under the action of the mounting rod 45, the fixed cylinder 11 and the settling cylinder 12 that have not tilted or settled make the fixed cylinder 11 and the settling cylinder 12 that have settled or tilted remain stable, and at the same time, the rotating connecting rods 44 connected at both ends of the mounting rod 45 pull the corresponding pull rods 43 to slide, and the pull rods 43 pull the third piston plate 41 to slide inside the second connecting box 40, so that the flowing liquid inside the second connecting box 40 flows into the third piston box 46, and the liquid level inside the third piston box 46 increases, causing the fourth piston plate 47 to slide inside the third piston box 46, and the fourth piston plate 47 drives the second ruler 48 to slide. The staff can roughly observe the second ruler 48 corresponding to the two ends of the mounting rod 45 The settlement distance of the fixed cylinder 11 and the settlement cylinder 12 that have settled or tilted is observed. When the settlement distance of the fixed cylinder 11 reaches the limit distance of the set standard, the fourth piston plate 47 squeezes the second trigger 49, and the second trigger 49 is electrically connected to the external control component, thereby reminding the staff. At the same time, when the fixed cylinder 11 tilts, the conducting ball 54 slides inside the horizontal box 50. Since the bottom end of the horizontal box 50 is arc-shaped, when the fixed cylinder 11 tilts slightly, the conducting ball 54 does not contact the first conducting ring 52. When the fixed cylinder 11 tilts more, the conducting ball 54 is tightly attached to the second conducting ring 53, and at the same time, the conducting ball 54 is tightly attached to the second conducting ring 53, so that the controller 55 is turned on, and the controller 55 is electrically connected to the external control component, thereby reminding the staff.
