Description

Technical Field

[0001] The utility model belongs to the technical field of land surveying, and in particular relates to a foundation pit surveying device for geotechnical engineering. Background Art

[0002] The foundation pit survey device is a device used in geotechnical engineering and construction engineering. It is mainly used for geological surveys before or during foundation pit excavation to obtain the physical and mechanical properties of the foundation pit and its surrounding rock and soil. The foundation pit survey device can help engineers understand geological conditions, evaluate foundation pit stability, and provide a basis for designing reasonable foundation pit support plans.

[0003] During use, the foundation pit survey device for geotechnical engineering is placed at a suitable location to be surveyed, and then the pin is rotated so that the pin drives the plug to be inserted into the soil, and the fixed frame on the lower side of the foundation pit survey device is fixed so that the fixed frame is fixed at a suitable position on the soil, and then the survey module is started so that the survey module surveys the foundation pit, thereby realizing the foundation pit survey of geotechnical engineering. However, in actual foundation pit survey, due to the uneven ground during survey, the survey module of the survey device needs to be set horizontally with the ground to ensure the normal progress of the survey. This requires personnel to place support blocks on the lower side of the fixed frame for auxiliary support, so that the fixed frame drives the survey module to be set horizontally. However, due to the different ground flatness in different places, the specifications of the support blocks are certain and there are certain errors in manual operation, the survey module will still tilt slightly during actual survey, which may affect the survey data of the foundation pit, resulting in certain errors in the measured data. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides a foundation pit survey device for geotechnical engineering. During foundation pit survey, the length of the four support legs can be freely adjusted according to the ground at the required survey location, so that the four support legs can stably support the survey module and keep it level with the ground, thereby ensuring the accuracy of the measurement data.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a foundation pit survey device for geotechnical engineering, including a base, an installation box is provided on the upper surface of the base, a branch pipe is provided between the installation box and the base, a detection head is provided at the lower end of the branch pipe, a detection module is provided at the top of the branch pipe, the detection module is electrically connected to the detection head through the branch pipe, evenly distributed slides are provided on the lower surface of the base, support legs are slidably provided inside the slides, the bottom ends of the support legs are rotatably provided with rotating plates, the upper surfaces of the rotating plates are slidably provided with plugs, and an adjustment module for adjusting the length of the support legs is also provided on the base; the outer side of the detection module is provided with a rubber sleeve.

[0006] As a further improvement of the present invention, the adjustment module includes a plurality of supports evenly arranged inside the base, symmetrically distributed guide rails are respectively arranged between two adjacent supports, sliding seats are respectively slidingly arranged between vertically adjacent guide rails, and connecting rods are rotatably arranged on the lower surface of the sliding seats. The ends of the connecting rods away from the sliding seats are respectively rotatably connected to adjacent legs, and an electric control unit for driving the sliding seats to move is also provided on the base.

[0007] As a further improvement of the present invention, the electronic control unit includes an adjusting screw rotatably arranged between two adjacent supports, the adjusting screws are respectively threadedly connected to adjacent sliding seats, and an electronic control component for driving the adjusting screw to rotate is also provided on the support; the electronic control component includes a motor arranged on a support close to the vertical center of the base, and the output shaft of the motor is respectively rotatably connected to the adjacent adjusting screws.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] Firstly, it drives different legs to extend downward to different lengths. By adjusting the lengths of the four legs respectively, the four legs drive the base to be set horizontally, thereby driving the detection module and the detection head to be level.

[0011] Secondly, the control panel calls the battery to adjust the rotation of motors in different positions, so that the motors drive the adjustment screws connected to them to rotate, and the sliding seats drive the legs and the slide cylinder to slide through the connecting rods, which can quickly and stably drive the detection module and the detection head to be level, ensuring the accuracy of the measurement data.

[0012] Third, through the coordination of the motor, adjusting screw, connecting rod and supporting legs, the length of the four supporting legs can be freely adjusted according to the ground at the required survey location, so that the four supporting legs can stably support the survey module and keep it level with the ground, ensuring the accuracy of the measurement data.

[0013] Fourthly, the rubber sleeve on the outside of the detection module can prevent damage caused by accidental bumps and avoid affecting the data measured by the detection module. BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention.

[0025] When foundation pit survey is required in geotechnical engineering, personnel hold the base 101 and move the base 101 to a suitable position, and call the battery 110 through the control panel 301 to adjust the motors 206 at different positions to rotate, so that the motors 206 respectively drive the adjusting screw rods 205 connected thereto to rotate, and then drive the sliding seat 203 to slide between the guide rails 202 by adjusting the threaded relationship between the screw rod 205 and the sliding seat 203.
