Construction method for pulling joint pipe in underground diaphragm wall section connection construction
The invention provides a construction method for pulling a joint pipe in underground continuous wall section connection construction. The construction method comprises the steps that a pressure sensoris installed on the pipe wall of a first joint pipe; the first joint pipe is hoisted into the joint hole; the multiple middle joint pipes are sequentially hoisted into the joint holes, then the tailjoint pipe is hoisted into the joint holes, and all the joint pipes are connected; and when concrete pouring in the slotted hole where the joint pipe is located reaches the demolding time and the pressure of the pressure sensor does not exceed the set pressure, the whole joint pipe is lifted upwards by the set distance. The method has the beneficial effects that the demolding time is accurately grasped, so that when the whole joint pipe is pulled out, joint hole shrinkage or collapse cannot be caused too early, and pipe wall dead casting cannot be caused too late; meanwhile, the pressure sensor is arranged on the wall of the first joint pipe, so that the burying depth and the pulling difficulty degree of the first joint pipe in concrete can be effectively monitored, the whole joint pipe cannot be buried too deep to be pulled out while the pulling time is met, and the construction efficiency is improved.
本申请提供一种地下连续墙墙段连接施工中接头管起拔的施工方法，包括：将首节接头管管壁上安装压力传感器；将首节接头管吊入接头孔内；将多节中间节接头管依次吊入接头孔内，再将末节接头管吊入接头孔内，各节接头管连接；当接头管所在槽孔内混凝土浇筑达到脱模时间且压力传感器的压力不超过设定压力时，将整体接头管向上提升设定距离。本申请的有益效果是：准确把握脱模时间使得整体接头管抽出时既不会过早造成接头孔缩孔或垮塌，也不会过晚造成管壁铸死；同时在首节接头管壁设置压力传感器可以有效监测首节接头管在混凝土中的埋设深度以及拔出的难易程度，使得整体接头管在满足抽出时间的同时不至于使得其埋设过深而难以抽出，提高施工效率。
