在每條高速進出口，我們都可以看到車輛兩側使用的高速收費島預制件，這是通過高速收費島模具生產出來的，從外形看，高速收費島模具廠生產的該模具像是一種船舶的頭，這種尖形---根據設計院的設計圖紙生產的。高速收費島模具廠按照提供的大樣圖進行生產，每條高速公路的進出口都會采用，因為尖形的設計起到了---的防撞以及警示---，所以這種形式的收費島預制件應用在了大多數高速公路進出口。這種大型的鋼模具是組合型的模具，是由頭加尾組合在一起，這樣兩套模板組合成收費島模具。
At each high-speed entrance and exit, we can see the high-speed toll Island prefabricated parts used on both sides of the vehicle, which are produced through the high-speed toll Island mold. From the appearance, the mold produced by the high-speed toll Island mold factory looks like a ship's head, which is sharp - produced according to the design drawings of the design institute. The high-speed toll Island mold factory produces according to the detailed drawing provided. It will be used for the import and export of each expressway. Because the sharp design plays a role of anti-collision and warning, this form of toll Island prefabricated parts is applied to the import and export of most expressways. This large steel mold is a combined mold,
