护栏网是高速公路交通安全设施工程领域的基本内容，它的作用是隔离公路用地，以防止人畜进入公路，有效避免非法占用公路用地，有效维护道路通行权，保障行车安全稳定。通常将其设置在道路边界上50cm的位置，每列之间的距离大约为3m。当在基础和柱子设计过程中需要预制混凝土时，预制组件的数量通常相对较大，并将对预制件的质量提出更高的要求。由于该技术措施在维护公路运行安全稳定过程中起着重要作用，因此对其进行研究具有一定的现实意义。
Fence is the basic content of highway traffic safety facilities engineering. Its function is to isolate Road land, prevent people and livestock from entering the highway, effectively avoid illegal occupation of road land, effectively maintain the right of way, and ensure the safety and stability of driving. It is usually set 50 cm above the road boundary and the distance between each column is about 3 m. When precast concrete is required in the design of foundation and column, the number of precast components is usually relatively large, and higher requirements will be put forward for the quality of prefabricated parts. As the technical measures play an important role in maintaining the safety and stability of highway operation, it has certain practical significance to study the technical measures.
