水泥路沿石的作用及技术参数
高速公路、市政道路等建设均离不开路沿石，俗称路缘石、路牙石、道牙石等等，根据道路线路铺设的基本要求，实际路沿石材质可以分为水泥路沿石及石材路沿石。
The construction of highways, municipal roads, and other roads cannot be separated from the use of curbstones, commonly known as curbstones, curbstones, curbstones, etc. According to the basic requirements for road laying, the actual material of curbstones can be divided into cement curbstones and stone curbstones.
相比传统工艺下的石材路沿石，为了避免其自然资源的浪费，基本上当下都使用水泥混凝土采用路沿石模具来预制浇筑生产，路沿石主要包括类别：
Compared to traditional stone curbstones, in order to avoid waste of natural resources, cement concrete is generally used to prefabricate and pour curbstone molds. The types of curbstones mainly include:
1.水泥路侧石，铺设于绿化带及路侧边（路面边缘或标定路面界限的预制混凝土的界石），用于合理规范公路建设及挡渣、挡土作用，一般在其边上均有铺设排水沟用于下水，防止路面积水。
1. Cement curbstones are laid on green belts and roadside edges (boundary stones of prefabricated concrete used to mark road boundaries or road edges), used to reasonably regulate highway construction and the role of slag and soil retaining. Generally, drainage ditches are laid on their edges for drainage to prevent road surface water.

2.水泥路平石，顶面与路面平起的混凝土路沿石，有标定路面范围、整齐路容、保护路面边缘的作用。一般与水泥路侧石组合施工，铺设角度与水泥路侧石呈直角，在设有排水沟工程项目上，也会把路平石同等于沟盖板使用。
2. Cement paving stone, a concrete curb stone with a top surface that is level with the road surface, has the function of demarcating the road surface range, neatening the road appearance, and protecting the edges of the road surface. Generally, it is constructed in combination with cement curbstones, and the laying angle is at right angles to the cement curbstones. In projects with drainage ditches, the flat stones are also used as trench covers.

3.水泥路肩石，多用于城市道路行车道与人行道之间，主要作用则是防撞及交通便利之用。
3. Cement shoulder stones are commonly used between urban road lanes and sidewalks, mainly for collision prevention and transportation convenience.

以上几种水泥路沿石都可以采用路沿石磨平抛光条纹机等专用机械加以二次加工达到仿石效果，在带来便利的同时更增加外形美观功效。
The above types of cement curbstones can be processed using specialized machinery such as a curbstone grinding and polishing stripe machine for secondary processing to achieve a stone like effect, which not only brings convenience but also increases the appearance and aesthetic effect.
水泥路沿石定义：
Definition of cement curbstone:
以水泥和密实集料为主要原料，经振动法、压缩法或以其他能达到同等效能之方法浇筑预制的铺设在路面路沿、边缘、路面界限及下水用路沿石。
Using cement and dense aggregates as the main raw materials, precast paving stones are poured by vibration, compression, or other methods that can achieve equivalent efficiency, and laid on the road edges, edges, road boundaries, and drainage curbs.
水泥路沿石规格：按其结构形状分为直线形路沿石和曲线形路沿石，直线形路沿石按其截面分为H型、T型、R型、F型、P型、RA型及异型等。异型规格型号一般都由拱需双方协商确定。
Specification of cement road edge stones: According to their structural shape, they are divided into straight road edge stones and curved road edge stones. Straight road edge stones are divided into H type, T type, R type, F type, P type, RA type, and special type according to their cross-section. The specifications and models of irregular shapes are generally determined through consultation between both parties.
