Construction must see: Quick solution for curved and rough edges of road hot-melt marking paint

The aesthetic appearance of road markings directly affects the visual order and driving safety of the road, but problems such as wavy lines, edge burrs, and misaligned joints often occur during the construction of hot-melt markings. TOP ROAD Technology Co., Ltd. combines over a thousand engineering practices to deeply analyze the causes of linear defects and provide systematic solutions to help you create smooth and accurate road markings.

1、 The four core causes of unattractive linearity

Layout deviation: Manual marking error or inaccurate positioning of the layout robot, resulting in a deviation of the reference line.

Equipment defects: Loose guide wheel of the marking vehicle, worn scraper or uneven pressure, resulting in jagged edges of the marking line.

Improper operation: The speed of the cart fluctuates between fast and slow, and the steering is unstable, forming a wavy line.

Environmental interference: Strong winds, slopes, or road bumps can affect equipment stability and cause linear distortion.

2、 Four step efficient repair plan

1. Emergency remediation of constructed markings

Partial correction: Use a hot air gun to soften the coating on the curved section, and use a scraper to re adjust the edges;

Covering and redrawing: After cleaning the base surface in severely deformed areas, apply a second coat and overlap the joints by 5cm before smoothing.

2. Precise debugging of equipment

Guidance system calibration: Check the clearance between the guide wheel bearings of the marking vehicle to ensure the straightness of the walking trajectory;

Scraper upgrade: Replace the high-precision alloy scraper with a smooth and burr free edge;

Pressure balance: Adjust the hydraulic device of the hopper to ensure uniform discharge of the coating.

3. Upgrading the layout process

Intelligent layout replaces manual labor: using the Three Ais intelligent layout robot, laser positioning error ≤ 2mm;

Double verification of baseline: spray temporary water lines after layout, visually check before construction.

4. Standardized operation training

Constant speed driving: The construction speed remains stable at 4-6km/h, and the speed decreases in advance on bends;

Technique enhancement: Train the pushcart driver to grip the handle with both hands and lean forward to reduce equipment shaking

3、 Preventive measures: Ensure linear aesthetics from the source

Base surface pretreatment: Before construction, repair road potholes, remove gravel, and ensure that equipment travels without bumps.

Environmental adaptation strategy: Install windproof covers on windy days and use equipment assisted traction systems on sloping sections.

Dynamic quality monitoring: Stop and check the linearity of the line every 200 meters of construction (with a deviation of ≤ 3mm in line detection).
