Pre-fixing-thermalizing springback water stop joint for underground diaphragm wall
The invention discloses a pre-fixing-thermalizing springback water stop connector for an underground diaphragm wall. The joint comprises an outer protection pipe, a rigid water stop plate, a pre-fixing-thermalizing system and a secondary grouting system. The memory steel plate and the rubber water-stop belt of the rigid water-stop plate are utilized to enhance the strength of the joint and increase the streaming path of underground water; the rigid water stop plate is fixed in the connecting joint through solid paraffin of the pre-fixing-thermalizing system, and the solid paraffin is melted through heating of an electric heating wire, so that the rigid water stop plate extends out of the connecting joint; and the compactness and the strength of the joint of the underground diaphragm wall are improved through the secondary grouting system. By the adoption of the method, the strength between the wall sections can be improved, the water stopping effect can be enhanced, and the method can be widely applied to construction of underground continuous walls and has the advantages of being easy and convenient to operate and good in integrity.
本发明公开一种地下连续墙预固定‑热化回弹止水接头。该接头包括外保护管、刚性止水板、预固定‑热化系统、二次注浆系统；其利用刚性止水板的记忆钢板和橡胶止水带，加强连接处的强度并增加地下水的绕流路径；通过预固定‑热化系统的固体石蜡将刚性止水板固定在连接接头内，通过电热丝加热将固体石蜡熔化使刚性止水板伸出连接接头外；通过二次注浆系统提高地下连续墙接头处的密实度和强度。采用本发明，可以提高墙段之间的强度并增强止水效果，可以广泛应用于地下连续墙的施工，并具有操作简便、整体性好的优点。
