Construction method of underground diaphragm wall and butt joint of underground diaphragm wall
The invention discloses a construction method of an underground diaphragm wall and a butt joint of the underground diaphragm wall. The construction method comprises the following steps that forward groove sections are formed in an underground structure by digging; first reinforcement cages with guide rail joints at the end parts are arranged in the forward groove sections, and cavities of which the height is higher than or equal to that of the forward groove sections are formed in the guide rail 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 guide railjoints are vertically cut to enable the cavities to communicate with the backward groove sections; second reinforcement cages of which the end parts are provided with riveting rods are arranged in thebackward groove sections, and anchoring ends of the riveting rods are arranged in the guide rail joints; and concrete is poured into the backward groove sections and the cavities. According to the construction method and the butt joint, the joint waterproof capacity of the underground diaphragm wall is improved, the construction is convenient, and the installation is easy and rapid.
本发明公开了一种地下连续墙的施工方法及其对接头，该施工方法包括以下步骤：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导轨接头的第一钢筋笼，所述导轨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浇筑混凝土；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，并对所述导轨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端部设有铆接杆的第二钢筋笼，使所述铆接杆的锚固端安装至所述导轨接头内；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，施工方便、安装简单快捷。
