老城区雨、污水合流干管施工工艺质量探析

我国城市化进程正进入快速道,目前大力发展中小城镇。在城市化历程中,随着人口的急剧增长和土地、能源的日益紧张,为了保证城市的可持续发展,人与自然必须和谐共存,尽量不破坏老城区的面貌。为响应化学建材组在《“十五”规划纲要》中提出的要加速淘汰能耗高、寿命短、不符合节能政策的落后产品,在实际工程中利用原有河道,根据具体情况,设计上在河道中采用玻璃钢夹砂管、高密度聚乙烯管(HDPE)两种管材相结合,并采用多种施工方案。

Discussion and Analysis of Construction Technological Quality of Rainwater and Sewage Combined Sewer in Old City Area

The urbanizing course is now coming into the high-speed way in China, and the middle-sized and small-sized cities and towns are being developed. In the course of the urbanization, with rapid increment of the population and the increasing tension of the land and energy sources, and in order to guarantee continuable development of the city, the human and the nature must harmoniously coexist, and the outlook of the old city area is not damaged to the best of our abilities. In order to respond the suggestion quickly to wash out the backward products having the high energy consumption, short service life and not complying with the policy of the energy saving put forward in << "the Fifteen" Planning Program>> by the chemical building material group and based on the detail conditions, two kinds of the pipe materials combined of the fiberglass reinforced plastic sand pipe and HDFE pipe are used in the rivers during the design, and many construction schemes are used.
