【摘 要】目前国内高等级高速公路主要采用热熔型标线施工,热熔型标线具有快速凝固,反光效果好,外观美观,使用寿命长等特征,在公路设计中广泛应用,当前社会经济发展较快,对产品质量要求越来越高,人工成本费用也不断增长,因此,热熔标线施工放样采用机械作业无疑将成为中国标线施工放样的主流。本文重点阐述的标线放样机在施工过程中改进后的优势。
【关键词】高速公路 标线放样机 优势
Abstract: At present the domestic high - grade highway mainly uses the hot melt marking construction, hot melt marking with rapid solidification, reflective effect, beautiful appearance, the use of long life and other characteristics, in the highway design widely used. The marking the waterline lofting technique, the domestic use of artificial "sling rope method, however, under the environment of the rapid development of today's society and labor costs rising, marking the lofting" sling rope "technology has disadvantages of slow speed, high cost, quality control. Today faster, on product quality requirements more and more high in economic and social development, labor cost is increasing. Therefore, hot melt marking construction lofting by mechanical operations will undoubtedly become the mainstream of China marking construction lofting. This paper focuses on line lofting improved machine in the construction process of the advantage.

高速公路的建设和发展是国家精力发展水平的风向标,其重要程度不言而喻,而我国目前高速公路的建设用突飞猛进来形容可谓毫不夸张,伴随着高速公路的高速发展,如何处理交通安全问题越来越成为亟待解决的难题甚至是高速公路发展的瓶颈问题!
“交通安全,重在避免”如何做到这句话,我想除了增强交通安全意识,加强交通安全管理外,还应该做好高速公路的基础设施工程建设,我们在这里谈一下交通标线施工放样的改革及进步。
目前我国标线施工过程中施工放样采用人工放样和机械放样两种:其中人工放样就是“甩大绳”方法,机械放样就是通过简易的改装设备进行放样,然而在当今社会高速发展和人工费用日益增长的环境下,标线人工放样技术存在速度慢,成本高,质量不好控制等缺点。在这里,我们先通过对比来介绍一下人工放样和机械放样的施工方法。
人工放样方法:按设计在地上标出标线的控制点,大概2~5米一个点;……
