路肩石是指位于车行道外缘至路基边缘，具有一定宽度的带状部分(包括硬路肩与土路肩)，为保持车行道的功能和临时停车使用，并作为路面的横向支承。保护行车道等主要结构的稳定：为发生机械故障或遇到紧急情况的车辆需要临时停车提供位置；可供行人、自行车通行；为设置路上设施提供位置。

The road shoulder stone refers to the strip part (including the hard shoulder and the earth), which is located outside the road edge to the edge of the roadbed, to maintain the function of the road and to use the temporary parking, and as the lateral support of the road. The stability of the main structure, such as the protection of the carriageway, for the vehicles requiring temporary parking for mechanical failures or emergency situations; for pedestrians and bicycles, to provide location for the installation of road facilities.

在我们的生活中，到处都有各种各样的模型与模具，但不知道大家是否详细观察过，有关路面边缘的界石，这些界石也都是用路沿石砌成的，其实它在构建之前，也必须是需要由路沿石模具来提前摆设，以便更好的建造真实的物体，那么这同时，路肩石模具最明显的优势之一。

In our life, there are various models and moulds everywhere, but I do not know if everyone has observed the boundary stone in detail. These stones are also built along the road along the stone. In fact, before the construction, it must be set up by the road along the stone, so that it can be better built. Objects, which, at the same time, are one of the most obvious advantages of shoulder stone molds.
