Super-large-diameter cast-in-place pile double-layer reinforcement cage with pre-buried pipes and manufacturing method thereof
The invention discloses a super-large-diameter cast-in-place pile double-layer reinforcement cage with pre-buried pipes and a manufacturing method thereof. The double-layer reinforcement cage comprises an inner ring reinforcement cage and an outer ring reinforcement cage, wherein the inner ring reinforcement cage is a cylindrical cage-shaped structure formed by winding a spiral stirrup on a plurality of inner ring longitudinal ribs in the axial direction; the outer ring reinforcement cage is a cylindrical cage-shaped structure formed by uniformly sleeving a plurality of stiffening hoops on a plurality of main ribs in the axial direction; the outer ring reinforcement cage sleeves outside the inner ring reinforcement cage; and the pre-buried pipes are inserted into the inner ring reinforcement cage and the outer ring reinforcement cage. According to the double-layer reinforcement cage, deformation of the reinforcement cage during hoisting is avoided, the pre-buried pipes are prevented from being damaged by plugging and unplugging of a guide pipe when the guide pipe is used for pouring concrete, and the bearing capacity of a super-large-diameter cast-in-place pile is ensured. According to the manufacturing method of the double-layer reinforcement cage, the outer ring reinforcement cage and the inner ring reinforcement cage are integrally manufactured, the reinforcement cages and the pre-buried pipes are integrally processed and formed at one time, the hole collapse phenomenon caused by lengthening and welding of the reinforcement cage and the pre-buried pipes is eliminated, and the construction efficiency is greatly improved.
本发明公开了一种带预埋管的超大直径灌注桩双层钢筋笼及其制作方法，其中，双层钢筋笼包括内、外圈钢筋笼；内圈钢筋笼为螺旋箍筋沿轴向缠绕在多根内圈纵筋上的筒型笼状结构；外圈钢筋笼为多个加劲箍圈沿轴向均匀套在多根主筋上的筒型笼状结构；外圈钢筋笼套在内圈钢筋笼外；内圈钢筋笼内和外圈钢筋笼内插入有预埋管。上述双层钢筋笼避免了吊装时钢筋笼变形，防止了导管浇筑混凝土时上、下插拔对预埋管的破坏，保证了超大直径灌注桩的承载力。上述双层钢筋笼的制作方法，采用外圈钢筋笼和内圈钢筋笼整体制作，钢筋笼和预埋管一次加工成型，消除了因钢筋笼和预埋管接长和焊接期间导致的塌孔现象，大大提高了施工效率。
