Description

Technical Field

[0001] The utility model relates to the field of civil engineering measurement auxiliary devices, in particular to a measuring instrument for civil engineering. Background Art

[0002] Civil engineering is an engineering discipline that involves the design, construction, and maintenance of various infrastructure and engineering projects, such as buildings, bridges, roads, tunnels, water conservancy projects, ports, dams, etc. During the design and planning stages of civil engineering projects, it is necessary to accurately measure the terrain, landforms, underground pipelines, etc. to obtain accurate geographic information data and provide basic data for engineering design. Therefore, a civil engineering measuring instrument is needed.

[0003] A Chinese patent document with the search publication number CN206640376U discloses a measuring instrument for civil engineering, including a base plate, a telescopic rod fixed to the top of the base plate, and a measuring instrument body fixed to the top of the telescopic rod. A running wheel is installed at each corner of the bottom of the base plate. The measuring instrument body includes a shell and a controller fixed in the shell. A distance sensor and a display screen are fixed to the outer wall of the shell. The distance sensor is used to measure distance information and transmit the distance information to the controller. The display screen is used to display the distance information processed by the controller. The controller is electrically connected to the distance sensor and the display screen respectively. A power generation box is fixed to the top of the base plate. Its beneficial effects are: strong practicality and good energy-saving effect, but this method is inconvenient to fix the base when in use, which causes the roller to drive the base to move, thereby causing the measuring instrument to move. If the measuring instrument cannot be stably fixed in a fixed position during use, its measurement results will be affected by the external environment, such as uneven ground, wind, vibration, etc., resulting in a decrease in measurement accuracy, affecting the quality and accuracy of the project. The movement of the measuring instrument will increase the uncertainty of the data, especially when measuring the horizontal plane and verticality. The movement will introduce additional errors, resulting in the accuracy of the measurement results being affected. Utility Model Content
