In road infrastructure maintenance, crack filling machine is an indispensable professional equipment, widely used in asphalt pavement crack repair operations. It can not only effectively prevent water infiltration, reduce further damage to the road surface, but also extend the service life of the road, reduce long-term maintenance costs, is a modern road preventive maintenance of the key tools.
First, the scope of application of the grouting machine
grouting machine is widely used in the following scenarios:
Highways, municipal roads, airport runways, industrial park roads
Cement and asphalt mixed pavement, plaza, parking lot
Irregular cracks, temperature difference cracks and micro-cracks caused by traffic pressure
Usually used in conjunction with grooving machine and blower, it can realize the complete crack treatment process, from grooving, cleaning to heating and material injection integrated construction.
Second, small grouting machine working principle analysis
small grouting machine adopts liquefied gas heating system, combined with thermal oil circulation technology, can quickly melt the asphalt grouting glue heating, and through the internal pressurized pump will be the material from the discharge port stable output, directly filled into the cracks. Some models are equipped with hand-held hose gun, which is convenient for operators to flexibly deal with cracks of different angles and depths.
C. Equipment Efficiency and Actual Capacity
The actual operating efficiency is affected by many factors:
Factors affecting the actual working efficiency are affected by a number of factors:
Trenching requirements If trenching is required, the progress depends on the depth of the trenching and the condition of the working surface.
Crack pattern The deeper and wider the cracks are, the more consumables and working time will be required.
Skillfulness of operation Skilled workers with good co-ordination can reach 2,000-3,000 meters/day.
Material properties The melting speed of the asphalt grouting adhesive and the ambient temperature will affect the efficiency.
Quantity of grouting material The average daily quantity of grouting material is 200-300 kg/set. 300 kg/group
Taking the conventional model YG-100L as an example, combined with electric mixing and automatic temperature control system, it can realize the speed of 20m/min under normal condition, which is suitable for repairing large cracks.
Fourth, a brief description of the construction process (how to construct a grouting machine?)
Road closure preparation: sign setting to ensure construction safety
Crack slotting: use the slotting machine to expand the crack, easy to fill the material
Seam clearing treatment: clean up debris and sundries by blowers
Heating the melt: preheat the grouting adhesive to a suitable temperature (around 180°C)
Grouting: Start the asphalt pump and inject the grouting material evenly.
Natural cooling: wait for the material to solidify and resume traffic
The whole process usually needs 4~5 people to cooperate, with the advantages of high construction efficiency and lasting effect.
