Sounding tube dredging device

Abstract

The invention discloses a sounding tube dredging device which comprises a base, wherein a center rotary drum is arranged on the base, an inhaul cable is wound on the center rotary drum, the end of the inhaul cable is connected with a gravity hammer, the gravity hammer comprises a cylinder, one end of the cylinder is connected with the inhaul cable, and the other end of the cylinder is open and forms a sharp impact end. According to the sounding tube dredging device, the gravity hammer is arranged to be cylindrical, one end of the gravity hammer forms a sharp impact end to achieve impact dredging of the sounding tube; and meanwhile, the inner side space of the cylinder forms the clamping space of an impacted object, so that the impacted object is taken out of the sounding tube; in this way, the gravity hammer can achieve impacting and can also achieve discharging of impacted objects.

Description

technical field [0001] The invention relates to building construction technology, in particular to a dredging device for acoustic measuring tubes. Background technique [0002] Acoustic tube, also known as pile foundation detection tube, is pre-buried in the concrete of the pile body during the construction of the building, and then when the quality of the concrete needs to be tested, the corresponding detection is carried out in the acoustic tube through the ultrasonic transmitting probe and receiving probe. Its basic basis is: when there are defects in the concrete, the parameters of ultrasonic sound velocity, sound amplitude, frequency and waveform are all reflected. [0003] Apparently, acoustic tubes are easily entered by concrete or other sundries during building construction. Based on this, the prior art is equipped with acoustic tube dredging devices. The existing dredging devices are divided into two categories, one is active impact, and the other is active impact. ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the existing technology is that, due to the large depth of the acoustic tube, the carding device of the active impact type must be specially configured, the high-pressure impact water pump, and the drill rig corresponding to the drill bit of the long-distance drill pipe are all special models, not construction. The commonly used water pumps and drilling rigs on the construction site can be used concurrently, so their configuration conditions are relatively high, and it is difficult to configure them universally

However, although the impact hammer of gravity impact is easy to configure, it does not have the function of transporting broken objects outside. It can only break the concrete in the acoustic tube, but it cannot discharge the broken concrete from the acoustic tube by itself.
