Reverse wall construction method
The invention relates to a top-down wall construction method, which relates to the field of top-down method construction, and comprises the following steps of: excavating a region with a preset width on the inner side of a construction structure to the bottom surface elevation of a lower guide wall, and excavating other regions to the bottom surface elevation of a support beam; binding an upper guide wall steel bar group, a ring beam steel bar group, a lower guide wall steel bar group and a support beam steel bar group, and connecting a connector to the lower end of the lower guide wall steel bar group; the upper guide wall formwork, the ring beam formwork, the lower guide wall formwork and the supporting beam formwork are fixed, soil is backfilled to the outer side of the lower guide wall formwork in the area with the preset width on the inner side of the construction structure, and the backfilled soil forms a slope at the lower end of a bottom formwork of the lower guide wall formwork; and the upper guide wall, the ring beam, the lower guide wall and the supporting beam are poured. A connector is embedded in the lower guide wall and connected with a side wall reinforcing steel bar set below, and the ring beam is stably connected with the side wall below. Pre-burying of the connectors is convenient to implement, materials are saved, the construction period is shortened, slopes are convenient to remove, and side walls are convenient to construct. A long lower guide wall is arranged on the lower portion of the ring beam, and the clearance of the working space on the top of the side wall is extended.
本发明涉及一种逆作墙体施工方法，涉及逆作法施工领域，包括以下步骤：施工结构内侧预设宽度的区域开挖至下导墙底面标高，其余区域开挖至支撑梁底面标高；绑扎上导墙钢筋组、环梁钢筋组、下导墙钢筋组和支撑梁钢筋组，在下导墙钢筋组下端连接接驳器；固定上导墙模板、环梁模板、下导墙模板和支撑梁模板，在施工结构内侧预设宽度的区域回填土体至下导墙模板外侧，回填土体在下导墙模板的底模下端形成斜坡；浇注上导墙、环梁、下导墙和支撑梁。下导墙预埋接驳器，接驳器与下方的侧墙钢筋组连接，环梁与下方的侧墙连接稳固。接驳器预埋便于实施，节省材料和工期，方便去除斜坡，施工侧墙。环梁下部设置较长的下导墙，延伸侧墙顶部作业空间的净空。
