[0002] The foundation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be done. For those who do not excavate deeply, the side slope can be used to make the soil slope stable. The slope size is determined according to relevant construction regulations. The prior art discloses a problem foundation pit horizontal displacement monitoring and alarm device, application number: CN202223229380.5. In order to solve the problem that the prior art requires technicians to spend a lot of energy and cannot grasp the state of the problem foundation pit in real time and issue early warning information in time, the work efficiency is low. By pulling the steel wire through the vertical steel drill fixed on the soil body where horizontal displacement occurs, the trigger component state is changed to activate the alarm component, and early warning information is issued in time. The technicians can stand far away from the problem foundation pit to inspect the safety state of the problem foundation pit, ensuring that the technicians can grasp the safety information of the problem foundation pit in real time and ensure personal safety. However, in the above technical scheme, the horizontal displacement alarm is connected to the ground by an independent vertical plug-in fixation at the center of the lower part, which has poor stability and is easily affected by the flatness and dilution of the ground and deflected, affecting the data accuracy of the detection end. Therefore, the inventor proposes a foundation pit displacement monitoring and alarm device. Utility Model Content

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.

[0023] This specific implementation method is a foundation pit displacement monitoring and alarm device, and its structural schematic diagram is as follows Figure 1As shown, it includes an alarm box 1, a detection rod 5, a swing rod 7 and a vertical rod 2. The swing rod 7 is symmetrically distributed at the four corners of the bottom of the alarm box 1. The detection rod 5 slides in along the side wall of the alarm box 1. The end of the detection rod 5 that penetrates into the interior of the alarm box 1 is fixedly connected to a moving block 13. The moving block 13 is slidably connected to the alarm box 1. The end of the detection rod 5 away from the alarm box 1 is connected to the vertical rod 2. A mounting block 4 is fixedly installed on the side wall of the bottom end of the alarm box 1. The interior of the mounting block 4 slides through a limiting rod 3, and the limiting rod 3 is adapted to be plugged into the limiting hole 11. A fixed block 6 is fixedly installed at the bottom of the alarm box 1. The fixed block 6 is rotatably connected to the swing rod 7. The swing rods 7 are symmetrically distributed in pairs. The limiting rod 3 penetrates into the limiting hole 11, so that the connecting shaft 10 is limited and fixed, and then the swing rod 7 is kept fixed in a vertical state, and then the swing rod 7 is inserted into the ground.

[0024] Reference Figure 2 A connecting shaft 10 is fixed between each two adjacent groups, and a limiting hole 11 is formed on the connecting shaft 10. The bottom of the swinging rod 7 has a spike head 12. A connecting block 8 is fixedly connected to the top of the swinging rod 7, and a rotating shaft 9 is protruded from the connecting block 8. The rotating shaft 9 is arranged opposite to the connecting shaft 10, and the rotating shaft 9 is rotatably connected to the fixed block 6. A moving groove for the moving block 13 to pass through is horizontally formed on the side wall of the alarm box 1, and a sliding groove 19 is formed on the inner wall of the bottom end of the moving groove.

[0025] Reference Figure 3 A fixing ring 17 is fixedly sleeved on one end of the detection rod 5 outside the alarm box 1 , and a spring 16 is connected between the fixing ring 17 and the alarm box 1 , and the spring 16 is sleeved on the outside of the detection rod 5 .

[0026] Reference Figure 4 A slider 15 is embedded in the slide groove 19, and the slider 15 is fixedly connected to the moving block 13. A pointer head 14 is protruded on the outer wall of the moving block 13. A numerical line 18 is provided on the outer wall of the alarm box 1 at one end corresponding to the pointer head 14. The detection rod 5 is tightened by the spring 16. If the vertical rod 2 is offset due to the displacement of the foundation pit, the upper detection rod 5 is pulled to move. At this time, the detection rod 5 drives the moving block 13 to slide along the alarm box 1. By observing the pointer head 14 on the moving block 13 and the number on the numerical line 18, it can be concluded whether the vertical rod 2 is offset.

[0027] Working principle: When in use, first rotate the swing rod 7 out from the fixed block 6 until the swing rod 7 is in a vertical state, then insert the limit rod 3 from the mounting block 4, and the limit rod 3 is inserted into the limit hole 11, so that the connecting shaft 10 is limited and fixed, and then the swing rod 7 is kept fixed in a vertical state, then the swing rod 7 is inserted into the ground, and the vertical rod 2 on the other side is inserted into the ground accordingly, and the detection rod 5 is tightened by the spring 16. If the vertical rod 2 is offset due to the displacement of the foundation pit, the upper detection rod 5 is pulled to move, and at this time the detection rod 5 drives the moving block 13 to slide along the alarm box 1, and by observing the pointer head 14 on the moving block 13 and the number on the numerical line 18, it can be concluded whether the vertical rod 2 is offset;

[0028] The swing rods 7 are located below the alarm box 1 and are oppositely distributed, so that the support of the alarm box 1 is increased. When the ground is uneven or the ground is loose, the alarm box 1 has higher stability, making the pulling data of the vertical rod 2 more accurate.
