Method for monitoring pouring perpendicularity of thin-wall hollow pier and positioning device
The invention discloses a thin-wall hollow pier pouring perpendicularity monitoring method and a positioning device. The thin-wall hollow pier pouring perpendicularity monitoring method comprises the following specific steps that S1, a foundation is poured; s2, hoisting and welding of a steel reinforcement framework; s3, sand filling and pre-pressing are conducted, specifically, a plugging transverse plate is installed in a sand discharging window, and a pouring cavity between the inner formwork and the outer formwork is filled with sand; s4, the perpendicularity of the formwork is checked and adjusted, and S5, sand filled in the step S3 is discharged, and concrete pouring is conducted. According to the thin-wall hollow pier pouring perpendicularity monitoring method, before concrete pouring, sand is used for pre-pressing a formwork system, formwork gaps and elastic deformation are eliminated, perpendicularity detection better conforms to the actual situation after concrete pouring, compared with a conventional method, the control precision is greatly improved, perpendicularity errors can be found in time, and the accuracy of concrete pouring is improved. The installation of the formwork can be adjusted by discharging sand, the loss caused by reworking after concrete pouring is reduced, and the construction quality and the construction progress of the pier are improved.
本发明公开了一种薄壁空心墩浇筑垂直度监测方法以及定位装置，包括以下具体步骤：S1、基础的浇筑；S2、钢筋骨架的吊装和焊接；S3、灌砂预压，在排砂窗口安装封堵横板，在内模板和外模板之间的浇筑腔内灌装砂子；S4、模板垂直度校核与调整，S5、排出步骤S3灌装的砂子，进行混凝土浇筑。本发明提出的薄壁空心墩浇筑垂直度监测方法，在浇筑混凝土前，使用砂子对模板系统进行预压，消除模板间隙和弹性变形，使垂直度检测，更加符合浇筑混凝土后的实际情况，比常规方法的控制精度有较大提高，且能够及时发现垂直度误差，能够通过排放砂子进行模板安装的调整，减少混凝土浇筑后再返工的损失，提高桥墩的施工质量和施工进度。
