一、问题的提出在地基处理工程中,塑料板排水是竖向排水的形式之一,已经得到广泛应用。该法首先出现于瑞典,随后逐渐发展到西欧、美国、日本等世界许多国家。现在世界上已有60多种不同型式的塑料板。但截至目前为止,还没有一个为国际公认的塑料板质量标准。而各产品国间,围绕塑料板的质量问题互相褒贬,使用户无所适从。在去年六月开始的我国天津新港东突堤地基处理国际投标工作中,可供选用的塑料板除荷兰、日本等国几家公司的产品外,还有我国的几种产品。各产品型号的技术性能不同,单价各异。究竟选用何种型号既可满足工程需要,又能节省成本?塑料板的质量标准是什么?这是摆在我们面前急待解决的问题。
First, the issue put forward In the foundation treatment project, plastic drainage board is one of the forms of vertical drainage, has been widely used. The law first appeared in Sweden, and then gradually developed to many countries in the world such as Western Europe, the United States and Japan. There are over 60 different types of plastic plates in the world today. But so far, there is no one internationally accepted plastic sheet quality standards. The products between countries, around the quality of the plastic board each other praise and disgrace, so that users know what to do. In the international bidding process for the foundation treatment of Tianjin New Port East Jetty started in June last year, the available plastic plates include several products in China in addition to the products of several companies in the Netherlands, Japan and other countries. The technical performance of different product models, different prices. What kind of model to choose both to meet the needs of the project, but also cost savings? What are the quality standards of plastic plate? This is before us in urgent need of solution.
