44、土方开挖完成后，为了实现出入口与车站主体的连接，需破除连接接口范围内车站主体围护结构地下连续墙的混凝土。根据需破除地下连续墙的实际位置、吊出空间及地质情况，计划采用分层分块、从外到里、从上到下的方式进行破除，每块面积不大于3，按顺序破除混凝土及钢筋并吊出。地连墙混凝土破除采用风镐并结合人工修凿的方法开凿。在凿除完最后一层混凝土之后，要及时检查连接洞口的净空尺寸，确保没有钢筋、混凝土侵入设计轮廓范围之内。其中3 号出入口及2 号风亭因破除长度达36.525m，为了确保破除作业时连接口上部结构的稳定，在破除作业前，采用钢支撑在顶板与混凝土支撑之间进行加固处理。4.1 脚手架搭设在需凿除地连墙范围内

45、搭设脚手架，脚手架主要使用材料为A48，壁厚为3.25mm 的普通钢管，直角扣件及旋转扣件，因不同功能需要分为载人脚手架，载物脚手架。载人脚手架为施工时仅用于上工人操作并携带单人能提携重量（不大于 50kg）的脚手架，载人脚手架设计最大步距不超过1200mm，横距不超过1050mm,纵距不超过 1200mm，纵向横杆、横向横杆与立杆均使用直角扣件连接。外部设置纵向剪刀撑，剪刀撑与与之相交的立杆使用旋转扣件连接，外部设置抛撑增加稳定性。具体设置详见图4.1及图4.2。文档编码:CL3N4H3W1G3 HF3J1A9B3D4 ZQ3H3J7V7O3文档编码:CL3N4H3W1G3 HF3J1A9B
