Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a measurement auxiliary tool for road and bridge construction. Background Art

[0002] When roads and bridges are being built, it is often necessary to make measurements in advance and then adjust the height between the panels. Then, formwork is assembled and positioning steel bars are inserted. The tools used are nothing more than surveying instruments, levels, tape measures, and rulers. After completion, the data is summarized and organized.

[0003] In the past, most measuring tools were directly wrapped and stored in boxes. When they were to be measured, they had to be taken out manually and used separately. Auxiliary tools were needed to perform fixed-point measurements at various locations on the bridge deck, and then multiple sets of parallel data were processed to obtain accurate results. It was difficult to ensure measurement accuracy by workers walking. If they could move on their own, it would shorten the measurement time and ensure measurement accuracy.

[0004] Therefore, we need to propose a new type of measurement auxiliary tool for road and bridge construction to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a surveying auxiliary tool for road and bridge construction, so as to solve the problem that the tool cannot move by itself in the above-mentioned background technology.

After the electric wheel is started, it can slide horizontally along the bridge plate, and no manual operation is required for positioning or moving;

[0015] 2. By winding a sling on the surface of the reel, the sling for measuring the water level can be wound up in the cavity on the front side of the pallet by meshing the pinion with the tooth block on the outside of the reel. Just turn the reel, and after the sling sinks to the bottom of the water under the gravity of the metal sinker, the sleeve block on the outside of the sling can float on the water surface by relying on the floating block at the bottom.
