首先来说，并不是所有的高铁都有护栏的，但是大多数为了安全考虑都是建有高铁护栏的，而现在高铁护栏的材质基本上有混凝土水泥防护栅栏，金属网片防护栅栏，一般是两者都有然后加上刺丝滚笼材料就组成了高铁护栏。
First of all, not all high-speed rail have guardrails, but most of them are built for safety. Now, the materials of high-speed rail guardrails are basically concrete concrete protective fence, metal mesh protective fence, generally both. Then, the high-speed rail guardrail is composed of barbed wire rolling cage material.
1、混凝土预制防护栅栏需在场地预制完成，可安部件分别预制，然后现场安装。2、高铁护栏可采用集中预制，加强预制产品的外观质量。3、采用的混凝土耐久指标应符合铁路混凝土结构耐久性设计暂行规定》，栏杆设计使用年限30年。4、高铁护栏所有的预埋件以及预留槽、孔的位置，尺寸必须准确无误，保证安装精度。
1. The prefabricated concrete protective fence shall be prefabricated at the site, and the installable parts shall be prefabricated separately and then installed on site. 2. Centralized prefabrication can be adopted for high-speed rail guardrail to enhance the appearance quality of prefabricated products. 3. The concrete durability index adopted shall conform to the temporary provisions for durability design of railway concrete structure, and the design service life of railings shall be 30 years. 4. The position and size of all embedded parts, reserved slots and holes of high-speed rail guardrail must be accurate to ensure the installation accuracy.
