A simple anti-floating device for reinforced cages of artificially dug piles

Abstract

The invention provides a simple reinforcement cage anti-floating device used for manual hole digging piles. The anti-floating device mainly comprises upper fixed non-return devices, lower fixed non-return devices, movable devices and concrete protective layer cushion blocks. Due to the arrangement of the anti-floating device, the floating condition of a reinforcement cage can be effectively controlled in the concreting process, the pile body protective layer can also be effectively controlled, and safety of the pile foundation structure is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a simple anti-floating device for a reinforced cage of a manually dug hole pile. Background technique [0002] During the pouring of manual excavated piles, a common quality problem is likely to occur-the floating of the steel cage. [0003] The reasons for its operation can be summarized as follows: [0004] ①Concrete pouring is too fast, the lifting conduit is too strong, and the recoil force of the concrete causes the reinforcement cage to float; [0005] ② The depth of the lower conduit is improper, causing the impact of concrete falling on the bottom of the reinforcement cage to be greater; [0006] ③ The conduit scratches against the reinforcement cage, and the reinforcement cage is also lifted up during the lifting of the conduit. [0007] For the above reasons, various anti-floating devices have emerged as the times require. Contents of t...
