Description

Technical Field

[0001] The utility model relates to a line marking device for infrastructure construction, specifically an unwinding trolley for construction line marking. Background Art

[0002] Before various construction operations such as bridge construction, building construction, and tunnel construction, it is generally necessary to sprinkle ash and draw lines to determine the construction area. When drawing lines, first pull a wire rope, and then construction workers shovel wiring powder with a spade or a bucket shovel and tap the spade or the bucket with their hands or wooden sticks along the wire rope, so that the powder falls to the ground to form white line segments required for excavation or construction. Due to the different tapping forces during the operation of the construction workers, the powder falls unevenly. When there is wind, the powder will float with the wind, affecting the clarity of the line marking. Content of the Utility Model
