前言 SMW法是日本一家中型施 工企业--成辛工业株式会社所 开发的一项专利,是在日本被广 泛应用的工法。该工法是以多轴 型钻掘搅拌机在现场向一定深度 进行钻掘,同时在钻头处喷出水 泥系强化剂而与地基上反复混合 搅拌,在各施工单元之间则采取 重迭搭接施工,然后在水泥土混 合体未结硬前插入H型钢或钢板 桩作为其应力补强材,至水泥结 硬,便形成一道具有一定强度和 刚度的、连续完整的、无接缝的 地下墙体。它是将H型钢的强度 和刚度与水泥土搅拌桩的抗渗性 能完好结合起来,同时具有承力 与防渗两种功能。
Preface The SMW method is a patent developed by Cheng Xin Industrial Co., Ltd., a medium-sized construction enterprise in Japan. It is a widely used method in Japan. The method is based on multi-axis drilling mixer to drill to a certain depth in the field, while cement at the drill bit Department of reinforcement and repeated mixing with the foundation, the construction unit is taken between the overlap lap construction , And then insert the H-shaped steel or steel sheet pile as its stress reinforcing material before the cement-soil mixture is not knotted, and form a continuous, intact and seamless underground wall with a certain strength and rigidity to the cement joint. . It combines the strength and rigidity of H-beam with the impermeability of cement-soil mixing pile, and has both functions of bearing capacity and anti-seepage.
