Abstract
Description
Technical Field
[0001] The utility model relates to concrete pouring, in particular to a device for vibrating during the concrete pouring process of a pile foundation. Background Art
[0002] When constructing a bored pile foundation, it is necessary to use a rotary drilling rig to dig the pile hole, then put down the steel cage, and then pour the concrete. During the pouring of the concrete, the concrete needs to be vibrated. In the existing construction method, it is necessary to manually hold the cable connected to the vibrator, and then hang the vibrator into the pile hole for vibration. With this vibration method, the staff needs to constantly move around the pile hole to drive the vibrator to vibrate the concrete in various places to ensure that the concrete is fully vibrated, and its work efficiency is relatively low; in addition, due to the large depth of the pile hole, the staff cannot effectively observe the vibration in the pile hole, nor can they ensure that the vibration is in place. They can only estimate based on experience. Even if the vibration time is extended, it is still impossible to effectively ensure sufficient vibration; furthermore, there is a lack of protective facilities around the pile hole, and personnel operate at the edge of the pile hole for a long time and constantly move, which poses a greater risk of collapse and endangers the safety of the staff.
