Construction method for out-of-well welding and graded descending of slide-resistant pile reinforcement cage
The invention discloses a construction method for out-of-well welding and graded descending of a slide-resistant pile reinforcement cage. The construction method comprises the following steps that before the reinforcement cage is constructed, a retaining wall locking opening and a retaining wall of a pile well hole opening of a slide-resistant pile are made according to design requirements, and the flatness of the top face of the retaining wall locking opening is guaranteed; 1, a scaffold is mounted; 2, a slide-resistant pile reinforcement cage descending device is mounted; 3, a primary reinforcement cage is constructed; 4, the reinforcement cage is descended in a grading manner; 5, a next-stage reinforcement cage is constructed; and the step 3 and the step 4 are repeated till grading construction and descending of the whole slide-resistant pile reinforcement cage are completed. According to the method, the defects that in the prior art, the reinforcement cage is manufactured and mounted underground, large hoisting equipment is needed, and construction is difficult are overcome; and the method has the advantages that construction is easy and convenient, the construction difficulty can be effectively reduced, the large hoisting equipment is not needed, the construction quality of the reinforcement cage can be effectively guaranteed, and the temporary occupied area is reduced.
本发明公开了一种抗滑桩钢筋笼井外焊接、分级下降的施工方法。它包括如下步骤，钢筋笼施工前，按照设计要求做好抗滑桩桩井孔口的护壁锁口和护壁，保证护壁锁口顶面的平整度；步骤一：安装脚手架；步骤二：安装抗滑桩钢筋笼下降装置；步骤三：施工第一级钢筋笼；步骤四：钢筋笼分级下降；步骤五：施工下一级钢筋笼；重复步骤三、步骤四，直至完成整个抗滑桩钢筋笼的分级施工以及下降。本发明克服了现有技术采用井下制作安装钢筋笼，需要大型吊装设备，施工困难等缺点；具有施工简便，能有效地降低施工难度、不需要大型吊装设备、并能有效保证钢筋笼施工质量、减少临时占地面积的优点。
