Orifice mounting device and construction method for hillside overweight pile foundation reinforcement cage construction
According to the orifice mounting device and the construction method for the mountainside overweight pile foundation reinforcement cage construction, a small and medium-sized tower crane at the mountainside is used for hoisting a profile steel support to a pile foundation hole position at the mountainside, and the profile steel support is fixed to the pile foundation hole position; the weight of a single section of the profile steel support and the weight of a single section of the overweight pile foundation reinforcement cage are both smaller than the maximum hoisting weight of the front end of the tower crane, the reinforcement cage is hoisted to the pile foundation hole opening position section by section, the reinforcement cage is supported through a profile steel carrying pole, then the next section of reinforcement cage is hoisted to the hole opening position, a reinforcement cage stress system is converted into chain hoist stress, and after two sections of reinforcement cage hole opening sleeves are connected, the tower crane is hoisted. And lowering the reinforcement cage by using the chain hoist, and repeating the steps until the reinforcement cage is mounted. The problems that a bridge pier construction shortcut located at the hillside position is difficult to build, hoisting of a reinforcement cage cannot be conducted through crane equipment, the distance between an installed tower crane and a hillside pier column is long, and the requirement for heavy hoisting of a large-tonnage pile foundation reinforcement cage cannot be met are solved. Belongs to the field of bridge pile foundation construction.
本发明提供一种针对山腰超重桩基钢筋笼施工的孔口安装装置及施工方法，该方法利用山脚的中小型塔吊将型钢支架吊装至山腰处的桩基孔位，将型钢支架固定于桩基孔位处，型钢支架和超重桩基钢筋笼单节重量均小于塔吊前端最大吊重，钢筋笼分节吊装至桩基孔口位置，将钢筋笼采用型钢扁担进行支撑，再吊装下一节钢筋笼至孔口处，将钢筋笼受力体系转换为链条葫芦受力，两节钢筋笼孔口套筒连接完成后，利用链条葫芦下放钢筋笼，重复以上步骤，直至钢筋笼安装完成。以解决位处于山腰位置的桥梁墩施工便道难以修建，无法采用吊车设备进行钢筋笼吊装，安装的塔吊距离山腰墩柱位置距离较远，无法满足大吨位的桩基钢筋笼重量吊装的问题。属于桥梁桩基施工领域。
