Abstract

The invention discloses a mounting structure and mounting method for precisely burying a cast-in-situ bored pile protection barrel. The structure comprises the protection barrel, multiple lifting rings are arranged at the top of the protection barrel, the lifting rings are connected with lifting ropes, the other ends of the lifting ropes are connected with hoisting hooks, the side wall of the protection barrel is connected with multiple horizontal inhaul cables, and the other ends of the horizontal inhaul cables are fixed to the ground outside a foundation pit through ground anchors. The technical problems that in the prior art, the protection barrel locating precision is not high, and monitoring cannot be achieved during operation are solved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an installation structure and an installation method for accurately embedding bored pile casings. Background technique [0002] At present, when the casing is buried, the center point of the pile position is generally first staked out on the ground, then the foundation pit is excavated, and then the center point is released at the bottom of the foundation pit (or stakes are set out around the foundation pit before excavation), and the casing is lifted by a crane It is lowered to the foundation pit for burial. During the lowering process, workers push and pull the casing according to the center point of the bottom of the foundation pit or the surrounding piles, so that the center of the casing coincides with the center of the pile position. Since the manual operation depends entirely on the experience level of the workers, and because the high casing height (1.5-3...
