Description

Technical Field

[0001] The present invention belongs to the technical field of deep displacement monitoring devices, and particularly relates to a landslide deep displacement monitoring device. Background Art

[0002] In projects such as slope treatment, embankment filling, earth excavation, and foundation treatment, it is necessary to monitor the deep horizontal displacement of the soil mass to understand the displacement deformation of the soil mass at different depths during the construction process and ensure construction safety. The deep horizontal displacement is usually monitored by an inclinometer. During monitoring, the inclinometer probe needs to be inserted into the inclinometer tube and slid down from top to bottom, and then the total deviation at each depth segment can be measured point by point on the reading instrument.

[0003] When the existing deep displacement monitoring device is in use, the traditional inclinometer tube cannot quickly and real-time monitor the horizontal displacement of the soil mass at different depths. Moreover, when the inclinometer tube is lowered, necessary protection is required to improve the accuracy of data and the efficiency of the project, which brings certain adverse effects to the use process; and when water seeps at the bottom or there is heavy rainfall resulting in internal water accumulation, the internal water accumulation cannot be processed, which may lead to inaccurate and unstable displacement monitoring, and even increase the risk of pipeline damage and misjudgment.

[0004] The present invention designs a landslide deep displacement monitoring device to solve the above problems. Summary of the Invention

[0015] 3. By hammering or pressing the pressure rod of the present invention, the pressure rod can be forced to move downward, driving one end of the connecting rod to move downward. Since the connecting rod is a rigid structure, the other end of the connecting rod will move outward, forcing the transverse insertion rod to move outward and insert into the soil, making the installation more stable.

The probe assembly includes a sensor probe 1201 and a cross-shaped stopper 1202. The cross-shaped stopper 1202 is installed on the push rod 11. An arm 12 is installed on the cross-shaped stopper 1202. The sensor probe 1201 is installed at the upper end of the arm 12. A sensor probe protection groove 1203 is provided inside the protective tube 3 above the sensor probe through hole 2. The upper end of the arm 12 extends into the sensor probe protection groove 1203. The top end of the push rod 11 extends to the upper side of the fixing plate 1. An electric telescopic rod 6 connected to the top end of the push rod 11 is installed on the fixing plate 1.

[0026] During use, the electric telescopic rod 6 is pressed down to drive the push rod 11 to move downward. The cross-shaped stopper 1202 enters the longitudinal chute 1204. The sensor probe 1201 slides out from the sensor probe protection groove 1203 and faces the position of the sensor probe hole 2. The sensor probe 1201 is in a working state. When not in use, the electric telescopic rod 6 is raised to drive the push rod 11 to move upward, so that the cross-shaped stopper 1202 blocks the sensor probe hole 2, playing a role of secondary waterproof sealing.

[0027] A water pump 9 installed on the upper side of the fixing plate 1 is provided inside the control box 4. A water suction pipe 7 and a flushing pipe 8 are respectively connected to the water inlet and outlet of the water pump 9. The water suction pipe 7 and the flushing pipe 8 extend to the bottom of the protective tube 3. A plurality of flushing nozzles 801 are provided on the flushing pipe 8. The positions of the flushing nozzles 801 correspond to the sensor probe through holes 2.

[0028] To prevent large impurities from entering the hollow pipe inside the protection pipe 3, a vertically extending annular groove is provided in the middle of the protection pipe 3. The lower end of the annular groove extends to the bottom of the protection pipe 3. A protection baffle 13 is provided inside the annular groove.

[0029] When the sensor probe is not in use, by rotating the rotating handle 1302, the protection nets 1303 are hidden inside the annular groove to seal the inside of the protection pipe 3. When the sensor probe needs to be used, the protection nets 1303 are rotated to the position of the sensor probe hole 2.

[0030] The ground plug assembly 5 includes a ground plug tip 501 and a ground plug post 502. The ground plug tip 501 is a conical structure. The ground plug tip 501 is installed at the bottom of the ground plug post 502 to facilitate inserting the ground plug assembly 5 into the soil. The ground plug post 502 is installed on the fixed plate 1. A transverse rod placement groove 511 and a pressure rod through-hole 510 located at the upper end of the transverse rod placement groove 511 are provided inside the ground plug post 502.

A plurality of transverse rods 505 are installed at the outer end of the movable block 504. A plurality of rod through-holes for the transverse rods 505 to pass through are provided on the outer wall of the ground plug post 502, so that the transverse rods 505 can extend out of the ground plug post 502 to make the ground plug assembly 5 more firmly inserted into the ground.

[0031] The pressure rod 508 is provided with bumps for fixing the position of the shaft sleeve 507. A T-shaped sliding groove 503 located on the inner wall of the transverse rod placement groove 511 is installed inside the ground plug post 502. A T-shaped sliding block that is clamped in the T-shaped sliding groove 503 is provided on the movable block 504. A pulling hole 509 is provided at the top end of the pressure rod 508 to facilitate pulling out the ground plug assembly 5 inserted into the soil.

[0032] By hammering or pressing the pressure rod 508, the pressure rod 508 can be forced to move downward, thereby driving one end of the connecting rod to move downward. Since the connecting rod is a rigid structure, the other end of the connecting rod will move outward, thereby forcing the transverse rods 505 to move outward and be inserted into the soil interior, making the installation more stable.

[0033] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
