Reducing joint of ultra-deep diaphragm wall joint pipe joint and construction method
The invention discloses a variable-diameter joint of an ultra-deep diaphragm wall joint pipe joint and a construction method. The variable-diameter joint comprises a large-diameter bottom pipe, and one end of the large-diameter bottom pipe is matched with a large-diameter insertion rod arranged at one end of a large-diameter joint pipe in an inserted mode through a large-diameter insertion groove; the other end of the large-diameter joint pipe is also connected with a large-diameter slot, the large-diameter slot is matched with the adjacent large-diameter joint pipe in an inserting manner, and a plurality of large-diameter joint pipes form a large-diameter pipe section; the end of the large-diameter pipe section is connected with the large-small-diameter connector, the other end of the large-small-diameter connector is connected with the small-diameter pipe section, and the small-diameter pipe section is formed by connecting a plurality of small-diameter connector pipes. The method solves the problem that in the prior art, the pipe drawing difficulty of the diaphragm wall connector pipe is large, and has the advantages that negative pressure is prevented from being generated at the bottom of the pipe drawing bench in the mode that grouting is actively conducted from the hole opening to the hole bottom, and therefore the pipe drawing difficulty is reduced.
本发明公开了一种超深防渗墙接头管接头的变径式接头及施工方法，装置包括大口径底管，大口径底管一端通过大口径插槽与大口径接头管一端设置的大口径插杆插接配合；大口径接头管另一端也连接有大口径插槽，与相邻的大口径接头管插接配合，多节大口径接头管组成大口径管段；大口径管段端部与大小口径连接头连接，大小口径连接头另一端与小口径管段连接，小口径管段由多节小口径接头管连接而成。该方法解决了现有技术的防渗墙接头管拔管难度较大的问题，具有可通过从孔口主动往孔底注浆的方式，避免拔管机底部产生负压，从而降低拔管难度的特点。
