路沿石压制成型新工艺

路沿石是道路附属设施中的重要组成部分,起到道路美化和对路面的保护作用,分为天然石材和混凝土材料两类。天然石材消耗自然资源,而混凝土旧法压制存在质量差、成本高、效率低的三大问题亟需解决。新工艺路沿石生产采用负压吸水压制成型工艺和新配方,一次成型只需3分钟,即可直接脱模达到搬运和码垛强度。与旧法相比,生产效率大幅提高,密实度提高10%,强度提高75%,外观光洁平整,达到天然石材表面效果。新法路沿石质量好、效益高,具备取代旧法路沿石和天然石材的市场基础。经在312国道镇江段实际使用,效果良好,验收合格。

Roadside stone is an important part of road ancillary facilities, which plays a role in road beautification and pavement protection, and which can be divided into two categories: natural stone and concrete materials. Natural stone consumes natural resources, but there are three major problems of poor quality, high cost and low efficiency in the old method of concrete pressing,which need to be solved. The new-process road stone production adopts the negative pressure water absorption pressing forming process and the new formula, and it only takes 3 minutes to release the mold directly to achieve the handling and palletizing strength.Compared with the old method, the production efficiency is greatly improved, the compactness is increased by 10%, the strength is increased by 75%, and the appearance is smooth, achieving the surface effect of natural stone. The new-type roadside stone quality is good, with a high profit, thereby has the market potential to replace the old-type roadside stone and the natural stone. After used in Jiangsu Province’s Zhenjiang section of National Highway 312, the effect is good and the acceptance is qualified.
