Description

Technical Field

[0001] The utility model relates to the field of level instruments, in particular to a road surface leveling instrument for road construction. Background Art

[0002] In road construction, the use of level measuring instruments is undoubtedly crucial. These precision instruments play a key role in ensuring that various elements of the construction process, such as road surfaces, bridges, tunnels, etc., are precisely maintained at the correct horizontal position. For example, a level is one of the commonly used level measuring instruments in road construction. The core function of a level is to determine the elevation difference between different points by observing the level line, thereby ensuring the accuracy of the construction elements in the horizontal direction.

[0003] However, in actual use, level measuring instruments also face some challenges. Since these instruments usually need to be in direct contact with the ground, they are inevitably affected by particles on the ground. These particles, such as dust, sand, etc., may interfere with the balance of the instrument when it is in contact with the ground, thereby affecting the stability and accuracy of the instrument.

[0004] To meet these challenges, construction workers usually need to take some measures to reduce the impact of particles on level measuring instruments. For example, they can clean the ground before measuring to remove particles such as dust and sand, but it is inevitable that there will be a small amount of particles that affect the placement;

[0005] In general, level measuring instruments play a vital role in road construction. They not only ensure the accuracy of construction elements in the horizontal direction, but also provide important support for the quality and subsequent maintenance of road construction. However, in order to ensure the accuracy and stability of these instruments, construction workers also need to take some measures to deal with the interference of external factors such as particulate matter. Through continuous technological innovation and operation optimization, we believe that level measuring instruments will play a greater role in future road construction. Utility Model Content
