Description

Technical Field

[0001] The utility model relates to the technical field of levels, in particular to a level adjustment auxiliary device and a level. Background Art

[0002] In construction projects, there are many road filling and excavation operations, and the excavation and filling elevation needs to be measured and controlled at any time during construction. For elevation measurement, the instrument we use is generally a level. When measuring, more than two people are required to cooperate in operation (one person reads the number, and one person sets up the tower ruler, neither of which can be missing). There are many excavation or filling work surfaces in road projects. During the period of heavy drought, more than a dozen roads are excavated and filled at the same time, and the technical requirements for roadbed flatness are relatively high. If the traditional method is used to measure the elevation with a level, one filling work surface needs to be equipped with more than two technicians, and one excavation work surface needs to be equipped with more than two technicians. In the case of construction of multiple work surfaces, the number of surveyors required is very large. Elevation measurement alone is also extremely wasteful of personnel. It can be imagined that it is difficult to achieve personnel reduction using conventional level equipment; using the traditional level measurement method, the level ruler sighting and focusing still need to be performed visually. When the operator observes for a long time, the naked eye is easily fatigued, which will lead to unclear or misreading of the tower ruler reading, resulting in differences in the measured elevation.
