Construction technology of granite blind stone

Construction technology of granite blind stone

 

　　The various detection indicators of the base should meet the design standards. When laying blind granite bricks, use wide lines to control the flatness and elevation at fixed points every 5m. Blind track stone laying requires square appearance and neat arrangement.

 

　　 Blind stone paving is the same as the paving method of sidewalk slabs, and attention should be paid to:

 

　　① When paving the sidewalk to a building, guide blind stones should be set continuously in the direction of travel, and stop blind stones should be paved in front of the intersection edge stones, and the paving width shall not be less than 0.60m.

 

　　② The tactile stone at the crosswalk is 0.30m away from the edge stone or a block of sidewalk bricks to pave the blind stone. The guide stone and the stop stone are pave vertically, and the paving width shall not be less than 0.60m.

 

　　③ At the bus stop, the five-lotus guiding stone shall be paved 0.3m away from the edge stone or a piece of sidewalk board. Temporary stop signs shall be provided with stop stones, which shall be paved vertically with the guide stones, and the paving width shall not be less than 0.60m.

 

　　④ The curb on the inner side of the sidewalk is at least 0.1m above the sidewalk in the green belt. The fracture of the green belt is connected with guide stones.
