摘要
通常地热深井施工周期长,施工中开挖的泥浆坑槽不仅会破坏土壤,还会增加后期恢复治理难度;生产、生活产生的大量固液废物也会对生态环境造成严重污染。随着“既要金山银山,又要绿水青山”的理念深入人心,以及国家对绿色勘查技术的大力支持,需要在设计、施工、完工阶段采取科学有效的绿色勘查管理技术手段,加强环境保护工作。雄安新区容东片区安居工程配套供热(冷)工程中深层地热项目作为国家重点安居工程,施工过程中通过优化井身结构、现场合理分区布置、采用“泥浆不落地”系统、科学化管理设备、制定及落实绿色勘查制度建设等措施,使施工中对环境的污染达到最小。绿色勘查技术在该项目地热井的应用,不仅提高了现场管理水平,更为打造智慧工地积累了宝贵、可借鉴的经验。
Usually, the construction period of geothermal deep well is long, and the mud pit excavated during the construction will not only destroy the soil, but also increase the difficulty of later restoration and treatment;a large amount of solid and liquid wastes produced in production and life will also cause serious pollution to the ecological environment. With the concept of "clear waters and green mountains are as good as mountains of gold and silver" gaining popularity and the strong national support for green survey technology, it is needed to take scientific and effective green exploration management technology means and strengthen the protection of the environment in the design, construction, completion stage. The deep geothermal project of the housing project supporting heating(cold) engineering project in the Rongdong area of Xiong’an New Area is a national key housing project. Through optimizing the structure of the wells, reasonable site zoning, adopting the "mud not fall to the ground" system, scientific management of equipment, and the development and implementation of the green exploration system and other measures, the construction process has achieved the minimum environmental pollution. The application of green exploration technology in the geothermal wells of the project has not only improved the site management level, but also accumulated valuable and referential experience to build smart sites.
