The use of fired bricks in road paving is quite widespread, but various problems may arise during paving, which are actually caused by improper construction methods and lack of follow-up work. Generally, during the process of laying fired bricks, the following quality issues are often encountered, which have an impact on the overall aesthetics of the project. The following is a detailed content:
1. The collapse phenomenon of the road surface after use is mainly due to the roadbed backfill soil not meeting the quality requirements, not being compacted layer by layer, or paving the road surface on frozen soil in severe cold seasons, and the settlement of the frozen soil road surface after the beginning of spring. Therefore, before laying road bricks, it is necessary to strictly control the construction quality of roadbed fill and cement mortar cushion layer, and it is not allowed to build road surface on frozen soil layer.
2. Loose board surface: After paving, it should be cured for 2 days, and the joints should be immediately filled and compacted. It is particularly important to handle the gaps between bricks on the roadside to prevent loose boards with loose gaps. Also, it is important to avoid getting on the car too early and crushing it.
3. Excessive deviation and unevenness in the flatness of the brick surface: Before paving, a horizontal elevation line must be drawn. A row should be built at each end as a standard, and then a straight line should be drawn to control the horizontal height based on the standard at both ends. During the paving process, a 2m ruler should be used to check the flatness at any time. If it does not meet the requirements, it should be repaired in a timely manner.
The operation of details in the construction process of fired bricks is quite important, and reasonable adjustments should be made according to the construction period and internal conditions to avoid unreasonable situations.
