Description

Technical Field

[0001] The present invention relates to the technical field of foundation pit deformation monitoring, and particularly to a foundation pit deformation monitoring device. Background Technique

[0002] Foundation pit engineering is an indispensable part of urban construction and plays an important role in aspects such as real estate and transportation infrastructure. However, due to characteristics such as harsh construction environments and long construction periods, foundation pit engineering has a series of safety risks. Foundation pit deformation, collapse, etc. may pose a major threat to construction workers and the surrounding environment. Therefore, how to effectively monitor the deformation of foundation pits has become an urgent problem to be solved.

Therefore, we need to propose a foundation pit deformation monitoring device. Utility Model Content

[0046] A No. 1 threaded rod 6, parallel and symmetrically arranged with the guide rod 4 up and down, also horizontally connected to the side of the mounting column 2;

[0047] A No. 1 motor 3, installed on the mounting column 2 and at the end of the No. 1 threaded rod 6, and is drivably connected to the No. 1 threaded rod 6.

[0048] Furthermore, in one example,

[0049] The guide rod 4 is connected to the connecting component, and the connecting component includes:

[0050] A slider 5, slidably penetrating through the guide rod 4;

[0051] A No. 1 sleeve 8, fixedly connected to the bottom of the slider 5;

[0052] A connecting rod 9, sleeved and fixed in the No. 1 sleeve 8, and the bottom section of the connecting rod 9 extends into the hollow of the foundation pit;

[0053] A number of screw holes 10, vertically arranged at equal distances on the connecting rod 9;

[0054] A positioning bolt 7, cooperatively connected with one of the screw holes 10 for sleeving and fixing the connecting rod 9 in the No. 1 sleeve 8;

[0055] A vertical rod 14, with one end fixedly connected to the connecting rod, provided with a No. 2 threaded rod 18, on which a measuring mechanism 11 is arranged and the upper end is connected to a No. 2 motor 12, and a slide rail is arranged on the side.

[0056] Further, in one example, a measuring mechanism 11 is connected to the slide rail on the side of the vertical rod 14. The measuring mechanism 11 includes:

[0057] A moving block 19, one end of which is fixed inside the slide rail on the side of the connecting rod 9. A cord displacement meter 24 is arranged inside, and a transparent protective cover 23 is provided on the outer shell. The outer side of the same end also penetrates through the No. 2 threaded rod 18;

[0058] A No. 2 sleeve 20, one end of which is fixedly connected to the other end of the moving block 19. A spring 25 and a cord 26 are arranged inside. The spring 25 is wound around the cord 26, and one end of the cord is fixedly connected to the cord displacement meter 24 of the moving block 19;

[0059] A sliding rod 21, one section of which is slidably sleeved inside the No. 2 sleeve 20, and a cord positioning mechanism 27 is arranged at the same end;

[0060] A roller 22, which is fixed to the other end of the sliding rod 21 and abuts against the side wall of the foundation pit.

[0061] Further, in one example, the monitoring assembly includes that both ends of the horizontal rod 15 are fixed to the bottom of the vertical rod 14 of the connecting assembly;

[0062] A No. 3 threaded rod 17 is arranged on the horizontal rod 15. The measuring mechanism 11 is arranged on the No. 3 threaded rod 17 and the upper end is connected to a No. 3 motor 16.

[0063] Among them, the second threaded rod 18 can drive the measuring mechanism 11 to move up and down along the side wall of the foundation pit under the drive of the second motor 12 to monitor the deformation at any height of the side wall of the foundation pit; the third threaded rod 17 can drive the measuring mechanism 11 to move left and right along the bottom of the foundation pit under the drive of the third motor 16 to monitor the settlement or uplift at any position of the bottom of the foundation pit.

[0064] Among them, when the monitoring device is working, the initial state of the spring 25 should be in a compressed state and have a certain amount of compression to ensure that the spring 25 can exert a thrust on the sliding rod 21 to ensure that the roller 22 on the sliding rod 21 is always in contact with the pit wall; an appropriate amount of compressible space should also be reserved in the initial state of the spring 25 to ensure that the spring 25 can naturally expand and contract when the foundation pit deforms or the monitoring assembly moves along the pit wall.

[0065] Among them, the rope displacement gauge 24 is in a stretched state at the initial state, that is, the measured value is not 0. During operation, when the retaining wall of the foundation pit undergoes a horizontal displacement towards the inside of the pit or the bottom of the foundation pit bulges, the soil body pushes the roller 22 and the sliding rod 21 to move, the spring 25 is further compressed, the rope 26 is shortened, and the value of the rope displacement gauge 24 decreases; when the retaining wall of the foundation pit undergoes a horizontal displacement towards the outside of the pit or the bottom of the foundation pit settles, the spring 25 elongates under the action of the elastic force stored in itself, the rope 26 further pulls the rope displacement gauge 24, and the value of the rope displacement gauge 24 increases; thereby obtaining the deformation displacement value of the foundation pit.

[0066] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
