Pile measuring hole obstacle clearing device based on ultrasonic drill bit

Abstract

The invention discloses a pile measuring hole obstacle clearing device based on an ultrasonic drill bit. The device comprises a cable, a counterweight block and an ultrasonic drilling machine; the ultrasonic drill bit is arranged at the front end of the ultrasonic drilling machine; an ultrasonic generator and a piezoelectric ceramic ultrasonic transducer are arranged in the ultrasonic drilling machine; the ultrasonic generator is electrically connected with the cable; the ultrasonic generator is electrically connected with the piezoelectric ceramic ultrasonic transducer through a control circuit; and the cable, the counterweight block and the ultrasonic drilling machine are all positioned in a pile measuring hole. The pile measuring hole obstacle clearing device based on the ultrasonic drill bit can effectively clear the blocked pile measuring hole, fills the blank on the clearing aspect of the pile measuring hole, solves the difficulty of incapability of measuring the pile measuring hole due to blockage, and is convenient in use, safe and efficient.

Description

technical field [0001] The invention belongs to the technical field of pile hole cleaning tools, in particular to a pile hole obstacle cleaning device based on an ultrasonic drill bit. Background technique [0002] Due to the advantages of no vibration, no soil extrusion, low noise, and suitable for use in densely built urban areas during construction, cast-in-place piles are widely used in construction. According to different hole-forming techniques, cast-in-situ piles can be divided into cast-in-place piles with dry operation, cast-in-place piles with mud retaining walls, and cast-in-place piles with manual digging. There is a small-diameter metal pipe inside the cast-in-place pile to measure whether there is a quality problem when the cast-in-situ pile is poured. [0003] However, due to natural and human factors, the pile holes of cast-in-situ piles are often blocked. The piles are several meters to tens of meters long, and the length of the pile holes is close to that ...
