How should PC bricks be installed? Today, the editor of Shuojing Building Materials will explain the installation process of PC bricks.
First of all, it is necessary to design and select the original soil to compact the ground according to the specifications. After compaction, the crushed stone is used to pounce on the now compacted road surface, and then compacted with a high-power roller, and then the mixed C25 concrete is spread on the now compacted crushed stone roadbed. The mixed cement mortar is now spread on the concrete cushion. At this time, pay attention to the flatness, and do not damage the already laid bottom together.
Then, the PC brick is installed to ensure that no debris can be attached to the PC brick device. The device also needs to be laid according to the specified graphics. Together, the lines must be uniform and uniform. The interval between each PC brick should be controlled between 2-4 millimeters. The intention of this is to reserve space for thermal expansion and contraction for the PC bricks, so as to avoid subsequent unevenness caused by thermal expansion and contraction. . Then, depending on the laying condition, when some bricks cannot be laid, the cutting operation is performed, and then the laying is performed.
In the end, the PC brick was compacted with a rubber hammer, and then fine sand was sprinkled into the gap, and finally it was ensured that the fine sand also filled the gap after tapping. After finishing the work together, the remaining sand is cleaned. After the completion, the overall height of the PC brick surface should be 4-6 mm higher than the nearby sewer, so that water accumulation will not occur.
