摘　　要：研制了一种新型仿花岗岩混凝土路缘石成型装置,重点解决了原成型生产工艺中存在的成型时间长、生产效率低、外观质量差等问题。经生产验证得出:新装置产品2 min内可形成一定初始结构强度,养护7 d抗压强度可达到设计强度的90%以上,生产效率与原干法生产工艺相当,较原湿法生产工艺,生产效率有一定提高,生产周期缩短,占用场地减少,生产成本降低;新装置产品抗压强度可达55 MPa,表观密度可达2400 kg/m3,较原工艺产品,物理力学性能有较大提高;新装置产品外观平整光滑。A new forming device for imitating granite concrete curb was developed,which focused on solving the problems of long forming time,production efficiency and poor appearance quality in the original forming process.The production verification shows that the initial structural strength of the new device product is 2 min,the compressive strength of the product can reach more than 90%of the design strength in 7d curing period,and the production efficiency is similar to that of the original dry process.Compared with the original wet process,the production efficiency is greatly improved,the production cycle is shortened,the occupied site is reduced,and the production cost is reduced.The compressive strength of the new device product reaches 55 MPa,the compactness reaches 2300 kg/m3,which is better than the original process.The physical properties of the process products have been greatly improved,and the appearance quality of the new device products is smooth,which avoids the shortcomings of rough and hollow appearance of the original dry forming process products.
