Cast-in-place pile hazard source identification early warning and pile body monitoring device

Abstract

The invention discloses a cast-in-place pile hazard source identification early warning and pile body monitoring device which comprises a monitor arranged on a reinforcement cage of a pre-buried cast-in-place pile, the monitor comprises a steel thin-walled tube, a sound wave receiver, a mechanical sensing strip, a central mechanical and acoustic processor, a storage unit and an early warning device, the sound wave receiver clings to the side wall of the steel thin-walled tube and is electrically connected with the central mechanics and acoustics processor through the oscilloscope, all the mechanics sensing strips are uniformly distributed on the steel thin-walled tube and are connected in parallel through cables, and outputs of the mechanics sensing strips are electrically connected with the central mechanics and acoustics processor through the analog-to-digital converter. The early warning device and the storage unit are electrically connected with the central mechanics and acoustics processor. The device can monitor the pile body quality during pile forming of the cast-in-place pile.

Description

technical field [0001] The invention relates to the technical field of potential safety hazards of urban foundation piles, in particular to a device for identification, early warning of danger sources of cast-in-situ piles and pile body monitoring. Background technique [0002] Due to low construction noise and simple construction, cast-in-situ piles are commonly used piles in urban buildings, but there is a lack of effective monitoring equipment and methods in the later stage. And in the future, buildings in the city will be continuously rebuilt, and in the excavation of deep foundation pits, it is necessary to support while excavating, and anchor rods (cables) are important support structures. If the position of the pile foundation of the nearby building is not correctly positioned or the pile foundation is shifted when the anchor cable is driven, the structure of the pile foundation will be easily damaged when the anchor hole is drilled, causing a safety hazard to the adj...
