It is an important part of road construction and maintenance management, aiming to ensure the structural stability and service life of the road.
[0003] A common detection method is to bury settlement plates inside the roadbed and measure the settlement regularly. This method is used to bury the settlement plates in foundations with a greater possibility of settlement. The detection equipment does not have any early warning or alarm structure, which requires manual observation and measurement at regular intervals and at fixed points. The workload is relatively large and the human resource investment is also relatively large. Utility Model Content

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-3The utility model provides a technical solution: it includes a settlement plate 1, a detection tube 2, a detection head 3 and a pole 4, the detection tube 2 is installed at the center position of the upper end of the settlement plate 1, the detection head 3 is installed at the upper end of the detection tube 2, a light strip 31 is fixed to the periphery of the upper end of the detection head 3, the upper end of the pole 4 passes through the settlement plate 1 and is located in the detection tube 2, a laser receiver 23 and a laser transmitter 22 are fixed in the detection tube 2 and above the pole 4, a reflector 42 is fixed to the upper end of the pole 4, a battery box 5 is fixed between the detection tube 2 and the detection head 3, a glass plate 21 is fixed in the detection tube 2 and above the pole 4, and the glass plate 21 is located below the laser receiver 23 and the laser transmitter 22.
[0018] An internal threaded tube 11 is fixed at the center position of the sedimentation plate 1, and the bottom of the detection tube 2 is threadedly connected to the internal threaded tube 11. The inner diameter of the internal threaded tube 11 is larger than the diameter of the vertical pole 4. An end threaded rod 24 is fixed to the upper end of the detection tube 2. A through hole is opened at the center position of the battery box 5. The end threaded rod 24 passes through the through hole and is threadedly connected to the bottom of the detection head 3. The bottom of the detection head 3 and the upper end of the detection tube 2 are respectively abutted against the upper and lower ends of the battery box 5, and a sealing gasket 6 is fixed at the connection.
[0019] An adjusting head 41 is provided at the upper end of the vertical pole 4, a reflecting mirror 42 is fixed on the upper end of the adjusting head 41, a lifting screw 43 is fixedly connected to the bottom of the adjusting head 41, and the bottom of the lifting screw 43 is threadedly connected to the upper end of the vertical pole 4, and a level 12 is fixed to the outer periphery of the upper end of the settlement plate 1.
[0020] Working principle: First, assemble the whole equipment, install the bottom of the detection tube 2 into the internal threaded tube 11, then pass the end threaded rod 24 through the through hole and install it at the bottom of the detection head 3, use the upper end of the detection tube 2 and the bottom of the detection head 3 to squeeze, fix the battery box 5, use the power supply in the battery box 5 to power the electrical equipment, and complete the assembly work. The operation is simple, and it is convenient to store and transport after it is not disassembled. Then fix the bottom of the vertical pole 4 to the rock layer under the foundation to keep it stable. Even if settlement occurs, the upper end height can be maintained. The settlement plate 1 is pre-buried in the detection position, so that the upper end of the vertical pole 4 passes through the internal threaded rod and is located in the detection tube 2. At the same time, the detection head 3 is exposed above the ground. At this time, the laser emitted by the laser transmitter 22 is received by the laser receiver 23 through reflection of the light-emitting mirror. When settlement occurs, the distance and angle between the upper end of the vertical pole 4 and the laser transmitter 22 change, and the laser signal cannot be received by the laser receiver 23, thereby issuing an alarm and triggering the light strip 31 to light up. After receiving the alarm signal, on-site detection is carried out without the need for regular and fixed-point detection, which greatly reduces the labor cost. When pre-buried settlement plate 1, the rotation of the adjusting head 41 can be used to drive the rotation of the lifting screw 43, so that the height of the upper end of the adjusting head 41 changes, ensuring that the laser receiver 23 can accurately receive the laser signal when pre-buried.
