Underground diaphragm wall construction method, joint and connecting structure
The invention discloses an underground diaphragm wall construction method, joint and connecting structure. The construction method comprises the steps that forward groove sections are formed in an underground structure by digging; first reinforcement cages with joints arranged at the ends are arranged in the forward groove sections, and cavities with the height higher than or equal to that of theforward groove sections are formed in the joints; concrete is poured into the portions, except the cavities, of the forward groove sections; backward groove sections adjacent to the forward groove sections are formed in the underground structure by digging after the concrete in the forward groove sections is solidified, and the joints are vertically cut to enable the cavities to communicate with the backward groove sections; second reinforcement cages and water stop belts located between the first reinforcement cages and the second reinforcement cages are arranged in the backward groove sections; and concrete is poured into the backward groove sections and the cavities. According to the method, the joint waterproof capacity of the underground diaphragm wall is improved.
本发明公开了一种地下连续墙的施工方法、接头及其连接结构，该施工方法包括步骤：于地下结构中挖设先行槽段；于所述先行槽段中安装端部设有接头的第一钢筋笼，所述接头内形成高度不低于所述先行槽段的空腔；于除所述空腔以外的所述先行槽段内灌注混凝土；待所述先行槽段中的混凝土凝固后于地下结构中挖设邻接于所述先行槽段的后行槽段，并对所述接头竖向切割使所述空腔与所述后行槽段连通；于所述后行槽段内安装第二钢筋笼以及位于所述第一钢筋笼和所述第二钢筋笼之间的止水带；于所述后行槽段以及所述空腔内浇筑混凝土。本发明提高了地下连续墙接缝防水能力。
