日本“大林组技术研究所”进行的冷沥青混凝土防渗墙现场试验,是在一个边长6.7×5.4米,深10米的矩形槽中进行的。防渗墙厚度为0.6米。地质情况是地面以下至4米左右皆为沙质粘土,其下为砂砾强透水层(K=3×10~(-4)厘米/秒)。冷沥青混凝土的配合比为: 水——81公斤;
The field test of cold asphalt concrete impervious wall carried out by Japan’s “Daelim Group Institute of Technology” was carried out in a rectangular groove with a side length of 6.7 × 5.4 meters and a depth of 10 meters. Diaphragm wall thickness of 0.6 meters. The geological conditions are sandy clay below about 4 meters above ground and gravel permeable layer underneath (K = 3 × 10 -4 cm / sec). Cold asphalt mix ratio is: water - 81 kg;
