Joint pipe bottom pipe used in underground diaphragm wall section connection construction
The invention provides a joint pipe bottom pipe used in underground diaphragm wall section connection construction, and relates to the technical field of joint pipes, the joint pipe bottom pipe comprises a pipe body, a plurality of supporting plates are arranged in the pipe body, a sealing plate is arranged at the bottom of the pipe body, and the bottom of the pipe body is conical. Through the conical design of the bottom, the demolding difficulty of the connector pipe is reduced, the connector pipe is conveniently pulled out, and meanwhile the hole forming space of the connector hole is not affected; the bottom pipe is provided with the tension spring, the one-way valve, the one-way valve and the ventilation pipe, and the two ventilation structures can ensure that the valve can be opened or the one-way valve is communicated with the atmosphere through the ventilation pipe when negative pressure occurs when the connector pipe is pulled out, so that the hole wall is prevented from collapsing due to the negative pressure.
本发明提供一种地下连续墙墙段连接施工中使用的接头管底管，涉及接头管技术领域，包括管体，所述管体内设有若干撑板，所述管体底部设有封板，所述管体底部为锥形。通过底部的锥形设计，降低了接头管脱模难度，方便接头管拔出，同时不影响接头孔成孔空间；通过底管设置张拉弹簧和单向活门、单向阀门和通气管，上述两张通气结构能够在接头管起拔时，确保出现负压时能够使活门打开，或使单向阀门通过通气管与大气连通，避免孔壁因负压坍塌。
