Background Art

[0002] Deep foundation pit refers to the project with excavation depth exceeding 5 meters (including 5 meters) or more than three basement floors (including three floors), or the project with depth not exceeding 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. Foundation pit engineering mainly includes the design and construction of foundation pit support system and earthwork excavation, which is a highly comprehensive system engineering. It requires close cooperation between geotechnical engineering and structural engineering technicians. The foundation pit support system is a temporary structure and is no longer needed after the underground engineering construction is completed.

[0003] The existing deep foundation pit engineering slope instability warning has the following disadvantages: 1. The warning device is installed in the foundation pit, and the fixing effect of the device is slightly poor. It is easy to tilt under the action of external forces such as wind, affecting the detection effect; 2. When the slope is unstable, cracks and gaps are generated inside. The existing devices mostly detect the slope pressure or displacement at a single position, and the detection effect is slightly poor. Therefore, improvements are made to the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a deep foundation pit engineering slope instability warning device in order to solve the above-mentioned problem. The rotation of the motor drives the screw a and the screw b to move downward and be inserted into the soil obliquely, which can fix the position of the mounting frame; the cooperation of multiple slide bars and vibrators can improve the overall detection and warning effect.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a deep foundation pit engineering slope instability early warning device, comprising a mounting frame, a slide frame is installed on the left side of the mounting frame, and there are multiple slide frames, the slide frame is slidably connected with a slide bar, the slide bar is inlaid with a pressure sensor, the slide bar is located on the right side of the support frame, the slide frame is located on both sides of the cross bar, the cross bar is inlaid with a vibrator b, the mounting frame is threadedly connected with a screw a, the screw a is threadedly connected with a bevel gear a, the bevel gear a is meshed with a transmission gear a, the transmission gear a is meshed with a transmission gear b, the transmission gear b is meshed with a bevel gear b, and the bevel gear b is threaded with a screw b.

[0007] Preferably, a bracket is installed on the top of the mounting frame, an alarm is installed on the bracket, and a solar panel is installed on the bracket.

[0008] Preferably, a spring is installed on the right side of the slide bar, the spring is located on the inner side of the slide, and the cross bar passes through the support frame.

[0009] Preferably, the mounting frame is installed with a limiting frame a, the limiting frame a is installed with a motor, and the output end of the motor is fixedly connected with a rotating shaft a.

[0011] Preferably, the mounting frame is installed with a limiting frame b, and the limiting frame a is located above the limiting frame b.

[0012] The beneficial effects of the utility model are:

[0013] 1. The rotation of the motor drives the screw rod a and the screw rod b to move downward and tilt into the soil, which can fix the position of the mounting frame; when the mounting frame is fixed, the rotation of the motors on the four sides of the bottom end of the mounting frame drives the connected rotating shaft a to rotate, and the rotation of the rotating shaft a drives the connected transmission gear a to rotate, and the transmission gear a meshes with the transmission gear b, which can drive the transmission gear b connected to the rotating shaft b to rotate, and the transmission gear a meshes with the bevel gear a, and the transmission gear b meshes with the bevel gear b. The bevel gear a and the bevel gear b are respectively located on both sides of the transmission gear, and there is a gap between the bevel gears. The rotation of the bevel gear a drives the threaded screw rod a to move downward and tilt into the soil below, and at the same time, the rotation of the bevel gear b drives the threaded screw rod b to move downward and tilt into the soil, and the screw rod a and the screw b cross, so the connection effect between the mounting frame and the soil is good, and the mounting frame is not easy to tilt.

[0014] 2. The cooperation of multiple slide bars and vibrators can improve the overall detection and early warning effect; multiple slide bars are installed on the left side of the mounting frame, and the slide bars are installed on the upper side, middle side and lower side of the mounting frame, and the end of the slide bar slidably connected in the slide bar abuts against the surface of the support frame, and a pressure sensor is embedded in the slide bar, and a spring is installed between the slide bar and the slide bar. When the slope is unstable, the support frame at the slope tilts inward to squeeze the inner slide bar, and the slide bar moves inward to squeeze the spring. The pressure sensor on the slide bar can continuously detect the pressure. After detecting the set value, the alarm is powered on and an alarm is sounded. The cross bar installed on the left side of the mounting frame passes through the support frame and is inserted into the slope. A vibrator b is embedded in the cross bar. Vibrator b emits an ultrasonic wave to the left. The emitted ultrasonic wave moves to the left and then reflects, so as to detect whether there is a crack on the left side of the slope. A vibrator a is installed at the top of the slope, and vibrator a emits an ultrasonic wave downward to detect whether there is a crack below. When cracks are detected at the slope due to instability, the alarm sounds an alarm. Whether the slope is unstable can be detected by the cooperation of multiple slide bars and vibrators, and the detection effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
