路緣石的(de)定義及分(fen)類
路緣石是設在路面邊緣的界石,也稱為道牙或緣石。它在路面上還區分車行道、人行道、綠地、隔離帶和道路其他部分的界線,起到保障行人,車輛交通安全和保證路面邊緣齊整的作用,同時起到利于排除路面水的作用。
Kerb is a boundary stone located at the edge of a road surface, also known as a curb or curb. It also distinguishes the boundaries of roadways, sidewalks, green spaces, isolation strips, and other parts of the road on the road surface, playing a role in ensuring pedestrian and vehicle traffic safety and ensuring the smoothness of road edges, while also facilitating the drainage of road water.
路緣石主要有:立緣石(側石),平緣石(平石)、專用路緣石(包括彎道路緣石、隔離帶路緣石、反光路緣石、減速路緣石)等。
The main types of curbs are: vertical curbs (side stones), flat curbs (flat stones), specialized curbs (including curved curbs, isolation strip curbs, reflective curbs, deceleration curbs), etc.
路緣石宜用石材或混凝土制作。在城市道路中,側平石通常設置在瀝青類路面邊緣,平石鋪在瀝青路面與側石之間形成街溝,也有用L道牙(側石與平石連體),適宜用于主車道兩側;
Kerbs should be made of stone or concrete. In urban roads, side stones are usually set at the edge of asphalt pavement, and they are laid between the asphalt pavement and the side stones to form a street ditch. They also have L-shaped teeth (connecting the side stones and the side stones), which are suitable for use on both sides of the main lane;
側石支護其外側人行道或其他組成部分(綠化帶),一般高出路面15~18cm。水泥混凝土路面邊緣通常僅設置側石,同樣可起到街溝作用。反光路緣石(貼反光材料),能提高道路夜間能見度,有助于行車安全。
The lateral stone support is generally 15-18cm higher than the road surface for its outer sidewalks or other components (green belts). The edges of cement concrete pavement are usually only equipped with side stones, which can also serve as street ditches. Reflective curbstones (pasted with reflective materials) can improve nighttime visibility on roads and contribute to driving safety.
.路緣石應穩固,線形平直,曲線圓順,縫寬均勻,表面潔凈不被污染,勾縫嚴密,不得阻水。
The curbstone should be stable, with a straight and straight line, a smooth curve, uniform joint width, a clean surface without contamination, tight joints, and no water obstruction.
2.路緣石強度及外形尺寸應符合設計要求,背墻混凝土應搗固密實。
2. The strength and overall dimensions of the curbstone should meet the design requirements, and the back wall concrete should be compacted and compacted.
3.安裝允許偏差:
3. Installation allowable deviation:
平順度不大于10mm(20米拉線取大值)
Smoothness not greater than 10mm (whichever is greater with a 20 meter pull wire)
相鄰高差不大于3mm(20米用塞尺取大值)
Adjacent height difference not greater than 3mm (use a feeler gauge to take the larger value at 20 meters)
縫寬正負3mm(20米用鋼尺量取大值)
The width of the seam is plus or minus 3mm (the larger value is measured with a steel ruler for 20 meters)
頂面高程正負10mm(20米水準儀測)
Top elevation plus or minus 10mm (measured with a 20 meter level)
外露尺寸正負10mm(20米用鋼尺量大值)
Exposed dimensions of plus or minus 10mm (maximum value measured with a steel ruler at 20 meters)
