During the use of the paver, various problems, large and small, often occur. Today, the Jinan paver rental manufacturer would like to share with us how to deal with the uneven paving surface during the operation of the paver.
① Heating temperature (the temperature of screed floor should be 120 ℃);
② Flatness of screed (uneven connection of base plate and uneven surface of base plate);
③ The speed of the rammer (if the rammer speed is too low, holes will appear; if it is too high, the surface will rise);
④ The walking speed is too fast and there is segregation;
⑤ Improper spiral height and segregation;
⑥ The leveling device is installed incorrectly (installed reversely, out of the sensing range, etc.), causing waves;
⑦ The subgrade is not smooth, the reference is not accurate, and the paving thickness is inconsistent, which causes the pavement to be white, and the rolling will cause displacement. If the material temperature is too low, it will also cause segregation and cracking of the paving surface.
Before operation, check whether the screed bottom plate is flat and whether there are sundries stuck on the bottom plate, and clean and adjust it in time;
Paving shall be carried out after the heating temperature reaches the requirements;
Spray diesel oil at hopper, scraper bin and screw to prevent oil stain;
The tamping hammer and paving speed shall be set correctly, and the screw height shall be twice higher than the paving surface;
Correctly install the leveling instrument (or the position of the balance beam probe height and connecting line);
Always observe whether the reference object is accurate;
When the drop of subgrade flatness is too large, padding treatment shall be carried out in advance.
This is all for dealing with the unevenness of the paving surface during the operation of the paver. If you have any questions, please come to our website at any time http://www.ycgjglcl.com Ask about it!
