摘要
为找出农村户用沼气池产生"漏水漏气"的原因而进行了多年的现场调查与分析。结果表明:混凝土沼气池在建造与使用过程中典型的裂缝部位主要有池壁与池底连接处,池体与进、出料管相交处,拱顶与圈梁连接处,拱顶与活动口相交处。并对各处裂缝产生的机理进行了详细的阐述,并提出了可行的预防措施。
In order to find out the reasons of the rural household biogas ＇water and gas leakage＇,the field investigation and analysis have been done for many years.The results showed that the typical cracks place in the concrete biogas digester：junction of biogas tank wall with the bottom,intersection of biogas tank body with the into pipe or discharge pipe,connection of biogas tank dome with the ring beam and intersection of biogas tank vault with the activity port.The mechanism of cracks were analyzed in detail,and the preventive measures were proposed.
