什么是路基
What is subgrade
路基由填筑或开挖而形成的直接支承轨道的结构。也叫做线路下部结构。路基与桥梁、隧道相连，共同构成一条线路。路基依其所处的地形条件不同，有两种基本形式： 路堤和路堑，俗称填方和挖方。
A structure formed by filling or excavation to directly support the track. Also called line substructure. The subgrade is connected with bridges and tunnels to form a line. According to the different terrain conditions, there are two basic forms of subgrade: embankment and cutting, commonly known as filling and excavation.

Generally speaking, the cover is used to close or cover the end or top of the section of a container, box or structure
路基盖板模具是由聚丙烯原料或者ABS树脂（丙烯腈-苯乙烯-丁二烯共聚物）经过高温融化注塑而成的方形塑料盒子。主要用于道路排水系统。
The mold of subgrade cover plate is a square plastic box made of polypropylene raw material or ABS resin (acrylonitrile styrene butadiene copolymer) through high temperature melting and injection molding. It is mainly used for road drainage system.
