Abstract

The invention discloses a steady type cast-in-place pile reinforcement cage positioning device. The steady type cast-in-place pile reinforcement cage positioning device comprises a working table, a bearing frame and a pile opening. A reinforcement cage is placed in the pile opening and the working table is installed at the top of the pile opening, a first sliding rail is installed on one side of the top of the working table through bolts, a first sliding block is slidably connected to the top of the interior of the first sliding rail and a first installation plate is welded to one side of thebottom of the first sliding rail, a first reinforcement cage positioning clamping plate is installed on one side of the first installation plate through fixing bolts, the first reinforcement cage positioning clamping plate and the first installation plate are located on one side of the reinforcement cage, a second sliding rail is installed on the other side of the top of the working table throughbolts, and a second sliding block is slidably connected to the top of the interior of the second sliding rail. According to the steady type cast-in-place pile reinforcement cage positioning device, byarranging a reinforcement cage swinging mechanism, a matched transverse positing mechanism and matched vertical positing mechanism, rapid positioning of the reinforcement cage in the pile opening canbe completed, the whole operation is convenient and fast, the installation accuracy of the reinforcement cage is high, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of engineering construction foundation construction, and in particular relates to a positioning device for a steel cage of a stable cast-in-place pile. Background technique [0002] With the rapid development of expressway construction in my country, due to reasons such as low design standards and increased traffic volume, many early-built road sections have been unable to meet the needs of current operations, and are facing problems such as reconstruction, expansion, and upgrading of road surface levels. In the future, In a period of time, expressway reconstruction and expansion will be a new upsurge. Bored piles are widely used as the foundation of structures, but there are strict requirements on the center deviation of the reinforcement cage according to the code requirements, especially for the pile-to-column structure, due to the deviation of the reinforcement cage, the pile foundation rework occasionall...
