Construction method for cutter suction type corner amplitude underground diaphragm wall pipeline crossing
The invention discloses a construction method for cutter suction type corner amplitude underground diaphragm wall pipeline crossing. The construction method comprises the following steps of: carrying out amplitude division on a reinforcement cage to obtain a special-shaped amplitude reinforcement cage containing a pipeline area, and a corner amplitude reinforcement cage, and cutting off the longitudinal bars and the horizontally distributed bars of the special-shaped amplitude reinforcement cage at a pipeline interference part to form grooves; carrying out guide groove construction on two sides of a pipeline through a grooving machine, and then, carrying out grooving and hole cleaning on a soil body on the lower part of the pipeline through a gas lift reverse circulation drilling machine; lowering the reinforcement cage; pouring concrete; and after initial setting of the concrete, conducting soil body excavation, chiseling the concrete at the groove position of the special-shaped reinforcement cage, splicing the vertical steel bars at the top and the bottom of the pipeline, additionally arranging stirrups along the circumferential direction of the pipeline, welding the stirrups and the vertical steel bars, additionally arranging the horizontal distribution steel bars at the top of the pipeline, and welding the horizontal distribution steel bars and the vertical steel bars. The pipeline penetrating through the diaphragm wall does not need to be changed and moved, and the construction method has the advantages of being safe, reliable and convenient in construction, the construction cost is saved, and the construction period is shortened.
本发明公开了一种用于绞吸式转角幅地连墙穿越管线的施工方法，包括以下步骤：对钢筋笼进行分幅，分为包含管线区域的异形幅钢筋笼和转角幅钢筋笼，将异形幅钢筋笼的纵筋和水平分布筋于管线干涉处进行截断形成凹槽；利用成槽机对管线两侧进行导槽施工，然后利用气举反循环钻机进行管线下部土体成槽，清孔；钢筋笼下放；浇筑混凝土；待混凝土初凝后，进行土体开挖，剔凿异形钢筋笼凹槽部位的混凝土，续接管线顶、底部的竖向钢筋，并沿着管线的周向增设箍筋，箍筋与竖向钢筋焊接，并在管线顶部增设水平分布筋，水平分布筋与竖向钢筋焊接。本申请可不对穿越地连墙的管线进行改移，具有安全可靠、施工方便、节约施工成本，缩短施工周期的优点。
