1 概述多头深层搅拌桩截渗墙技术是运用多头深层搅拌桩机,把水泥浆喷入土体并搅拌形成水泥土墙,既能对软弱地基进行加固,又能防渗,具有成墙效果好、强度高、抗渗性能好、耐久性好、造价低、工艺简单、综合工期短、取材方便、适用土层范围广等特点,广泛应用于防渗工程、防洪墙基础工程、堤防加固工程、城市堤防工程中。目前,国内广泛使用一种双轴驱动两头或 1 Overview Deep deep mixing pile cut-off wall technology is the use of deep deep mixing pile machine, the slurry sprayed into the soil and stirred to form a cement wall, both for weak foundation reinforcement, but also impermeable, with a wall effect , High strength, good impermeability, good durability, low cost, simple process, short integrated duration, convenient drawing, wide range of applicable soil, etc. It is widely used in seepage control projects, flood control wall foundation works, dike reinforcement works, City embankment project. At present, a biaxial driver is widely used in China
