| 摘要: | 台灣地區每年因工程上需要產生營建剩餘土石方達數千萬立方公尺，其中兩階段申報之土質代碼中屬於B6：淤泥或含水量大於30%之土壤及B7：連續壁產生之皂土，因其實務上處理費用高，再生利用率低，故常遭不肖業者違規棄置或違法處理，造成環境汙染。 本研究工作項目有三：一、透過研究，探討營建泥漿產出的源由及處理方法。二、建立全套的營建泥漿之管理制度，包含產出源、流向及收容處理場所之設置及管理模式。二、透過前述研究過程，探討現有再利用的方法及技術，以及運用在營建泥漿的可能性，以鼓勵業者朝「生態城市綠建築方案」及「綠色內涵」之目標邁進，進而為地球盡一份心力。 如需完成上述目標，先經由文獻蒐集與營建淤泥相關自治條例或自治規則，辦法，相關研究報告，可輔助流向管理之工具或技術，之種類、數量及探討其與申報量之差異原因，，再經調查現行土石方資源堆置處理場所營建淤泥處理能力及目淤泥處理，並探討國內外對於營建淤泥之後端通路。最後，藉由訪談及蒐集彙整地方政府、工程承商及場所業者對於營建淤泥之處理及管理方式之建議，本研究研擬營建淤泥先行處理土壤塑性限度審認方式與相關處理設備、功能及末端處理之規範草案，以提升土石方資源堆置處理場所處理淤泥之能力與品質。 Due to needs of construction, the tremendous amount of waste soil had been produced in Taiwan every year. In the sequence index of waste soil, B6, containing more than 30％ of sludge or water, and B7 ,Bentonite conducting by settling slurry wall, are extremely difficult to dispose firm because of badly efficiency in recycling and high expenditure in dealing fee. Therefore, it has been tackled illicitly and disposed illegally, and then contaminating environment seriously. For encouraging constructors towards the goal of sustainable city and green living three systematic steps are revealed in this research：1. Exploring the source and disposal of waste soil. 2. Establishing the control mechanism, including source, distribution, regulation and management. 3. Discussing the possible usage and reclamation of waste soil, embodying with current techniques and experience. Moreover, to approach the goal, two main phrases had been taken. 1. Researching the capacity of tackling sludge and waste soil dispose in soil-recycling fields and terminal distribution. In this stage, several current municipal laws and acts had been evaluated, and then analyzed the discrepancy of declaration amount in waste soil with different codes. 2. In the final stage, after interviewing and collecting suggestions abstracting from local governments and constructors, the Soil Plastic-limit Disposal Code, emphasizing on relative equipment of dealing waste soil and terminal disposal, had drafted in order to improve the quality and efficacy of soil-recycling fields. |
