九、接头地下连续墙的接头可分作两大类:施工接头和结构接头。施工接头是浇筑地下连续墙时连接两相邻单元墙段的接头;结构接头是地下连续墙墙体与地下结构物其他构件(梁、柱、楼板等)相连接的接头。 (一)施工接头施工接头通常是利用两相邻单元墙段接触面上的摩擦力、两相邻单元墙段水平钢筋或钢板的搭 Ninth, joints of underground continuous wall joints can be divided into two categories: construction joints and structural joints. Construction joints are joints that connect two adjacent unit wall sections when the underground continuous wall is poured; structural joints are joints between the underground continuous wall and other components (beams, columns, floors, etc.) of the underground structure. (1) Construction Joints The construction joints are usually made by utilizing the frictional force on the contact surfaces of two adjacent unit wall sections, horizontal steel bars or steel plates of two adjacent unit wall sections.
