用沥青混凝土作为防渗结构是一项新技术,在国外已较广泛地应用,建成的沥青防渗工程数以千计。我国从70年代开始应用于库、坝作防渗面层,已建造50多项工程,个别地区还试验性应用于小型池、塘防渗。我公司于1984～1986年间在国内首次应用于大型水池工程,先后建成了两座10万m~3以上的大型蓄水池,克服了用钢筋混凝土建造大型水池存在的结构适应变形能力差,接缝处理复杂,易出现裂缝漏水或渗透,维修困难,钢材、木材、水泥用量大,造价高等问题,取得了良好的技术经 The use of asphalt concrete as an anti-seepage structure is a new technology that has been widely used in foreign countries. The anti-seepage engineering of asphalt has been built up to thousands. Since the 1970s, China has applied to reservoirs and dams as an impermeable surface layer. More than 50 projects have been constructed, and individual areas have also been experimentally applied to small pools and ponds for seepage prevention. Our company was first used in large-scale pool projects in China between 1984 and 1986. Two large-scale reservoirs with a capacity of more than 100,000 m 3 have been built, which overcomes the poor adaptability of the structures that exist in the construction of large pools of reinforced concrete. The seams are complicated to handle, prone to leakage or penetration of cracks, difficult to maintain, large amounts of steel, wood, cement, high cost, and good technology.
