Description
技术领域technical field
本发明涉及大型锚锭基础建造技术领域。更具体地说,本发明涉及一种超深地连墙钢筋笼翼缘排插钢筋匹配制造胎架及施工方法。The invention relates to the technical field of large-scale anchor foundation construction. More specifically, the present invention relates to an ultra-deep ground connecting wall steel bar cage flange row inserting steel bar matching manufacturing tire frame and construction method.
背景技术Background technique
在锚碇基础施工中圆形基坑可以发挥地连墙的拱效应,受力以竖向弯矩为主,回字型支护结构隔舱尺寸大、基坑深,以水平弯矩为主。在大新型回字型支护转结构超深地连墙锚碇基础中,传统接头不满足受力要求,需采用新型承插式刚性接头。新型承插式刚性接头与承插式钢筋笼匹配搭接共同构成地下连续墙刚性骨架,浇筑后期混凝土后形成完整的地下连续墙。In the anchorage foundation construction, the circular foundation pit can exert the arch effect of the ground connection wall, and the force is mainly the vertical bending moment. The back-shaped support structure has a large compartment size and a deep foundation pit, and the horizontal bending moment is the main force. . In the ultra-deep ground wall anchorage foundation of the large new back-shaped support and transfer structure, the traditional joints do not meet the force requirements, and a new type of socket-type rigid joint is required. The new socket-type rigid joint and the socket-type steel cage are matched and lapped together to form the rigid skeleton of the underground diaphragm wall, and a complete underground diaphragm wall is formed after the concrete is poured later.
在施工过程中,首先要安装承插式刚性接头,待承插式刚性接头安装到位后再安装承插式钢筋笼。承插式刚性接头在安装时手结构形变、分节对接偏差等影响,其线型和垂直度存在一定的偏差,这就导致后期承插式钢筋笼安装空间出现偏差,使承插式刚性接头与钢筋笼翼缘搭接处出现干涉。为保障承插式钢筋笼顺利下放安装,避免出现“卡笼”现象,就需要对承插式钢筋笼进行匹配制造。During the construction process, the socket-type rigid joint must be installed first, and then the socket-type steel cage will be installed after the socket-type rigid joint is installed in place. The socket-type rigid joint is affected by the deformation of the hand structure and the deviation of the joints during installation, and there is a certain deviation in its line shape and verticality, which leads to deviations in the installation space of the socket-type steel cage in the later stage, making the socket-type rigid joint Interference with cage flange laps. In order to ensure the smooth lowering and installation of the socket-type reinforcement cage and avoid the phenomenon of "cage stuck", it is necessary to match the socket-type reinforcement cage.
