摘要
针对目前工业遗留用地环境修复存在的常见问题,结合"环境修复+开发建设"模式,提出了污染场地地下空间利用原位自平衡策略.利用深厚不透水地层、横向止水帷幕、混凝土土壤阻隔形成封闭空间,隔绝污染土;结合场地内污染土自平衡、地下空间开发要求,将地下空间分成全利用、局部利用、(污染土)储土空间,克服修复难度大、周期长、成本高等难点.在项目应用中,结合BIM技术制定精准的实施方案,确保了自平衡策略的落地性,保障了人居环境安全、盘活了稀缺用地资源、节约修复资金80%,值得进一步完善推广.
Abstract
Aiming at the common problems in the environmental restoration of industrial legacy land,combined with the"environmental restoration+construction"model,an in-situ self-balancing strategy for the utilization of underground space in polluted sites is proposed.Using deep impermeable layers,horizontal waterproof curtains,and concrete vertical soil barrier to form enclosed spaces isolate polluted soil;Com-bining the requirements of self balancing of contaminated soil and underground space construction,the underground space is divided into ful-ly utilized,partially utilized,and(contaminated soil)storage spaces to overcome the difficulties of difficult restoration,long cycle,and high cost.In project practice,the application of BIM technology to develop precise implementation plans ensures the implementation of self balancing strategies,guarantees the safety of the living environment,revitalizes scarce land resources,and saves 80%of repair funds.It is worth further improving and promoting.
