Curb stone refers to the boundary stone used for the edge of the pavement by casting stone or concrete blocks. Curb stone is also known as dental stone, along the way stone and dental stone. Curb stone uses the pavement to distinguish the boundary line of lane, sidewalk, green space, isolation belt and other parts of the road, which plays the role of ensuring the traffic safety of pedestrians and vehicles and aligning the edge of the pavement. The shapes of stones along the road include vertical, inclined and flat, and walk on roadside stones, Through simple and effective walking methods, we can adjust the balance of the body's internal organs, increase fun, prevent and treat diseases, ensure the traffic safety of pedestrians and vehicles, and play a neat role along the edge of the road. We can dig ditches, install and reinforce the back of the road from the end of the road. This paper introduces the construction technology of the stones along the road, and summarizes the quality requirements and precautions of the stones along the road, so as to ensure the construction quality and improve the beauty of the road.
Characteristics of curb stone: according to different materials, curb stone is generally divided into concrete curb stone and stone curb stone. According to the section size of curb stone, it can be divided into H-type curb stone, T-type curb stone, R-type curb stone, F-type curb stone, TF type vertical curb stone and p-type flat curb stone.
1. The road must be paved along the stone through line construction. The top surface of the side plane indicates that the high-level line is tight. Use the wire rope to make the side flat stone. The side flat stone must be stable. Please avoid closing after tilting forward. The top line of the side plane is smooth and smooth without high-low offset, and the plane has no upper and lower offset, internal and external offset.
2. The foundation of the road must be built along the stone, and the foundation must be tamped. It is strictly prohibited to block the gap.
3. The deviation of the road along the stone joint is less than 1mm; The side lights and blocks must be equally staggered in the middle.
4. The flat stone on the side of the curb must ensure that the size and gloss meet the design requirements and have a beautiful appearance. The side stone of the curve part shall be specially processed according to the design radius, and the curve stone shall be known in advance to ensure the smooth, round and tight gap during the construction. The arc side stone must be grinded after manual fine excavation.
5. The road must be compacted along the stone back, with a width of more than 50mm and a thickness of more than 15mm.
6. The stone hook along the road (when hanging the hook, the line must be hung to remove the garbage in the side stone hook, wet the road with water, and then fill the gap with 1:2.5 cement mortar to firmly fill the hook.
7. Hang the side flat stone and properly water it for maintenance after installation.
Maintenance of curb stones: do not touch acidic objects. All curb stones are afraid of alkalinity. For example, acid often causes the oxidation of sulfur and iron minerals in granite to produce yellow coloring, while acid will divide the calcium carbonate contained in marble to form the appearance of corrosion. Alkali also corrodes the grain boundaries of feldspar and quartz silicide crystals in granite, forming a color ring for grain peeling. Therefore, non neutrality will damage the mirror surface of stones along the way, Please do not wax the stones along the way.
