Device and method for detecting sealing pressure resistance of sounding pipe for cast-in-place pile

Abstract

The invention provides a device for detecting the sealing pressure resistance of a sounding pipe for a cast-in-place pile and a method using the device. The device comprises a sealed container, an endcover assembly and a hydraulic lifting mechanism, wherein the sealed container is used for containing hydraulic oil, the end cover assembly is connected to an opening in the top end of the sealed container in a sealed mode, and an elastic gasket is arranged on the lower surface of the end cover assembly; the end cover assembly and the elastic gasket are further provided with ventilation openingsused for communicating with the interior of the sounding pipe; the hydraulic lifting mechanism is arranged in an inner cavity and positioned below the elastic gasket, and comprises an oil filling shell and a lifting table; the oil filling shell is provided with an oil filling cavity used for containing hydraulic oil, and the oil filling shell is further connected with an oil pipeline; and the lifting table or the oil filling shell is used for abutting against the end part of the sounding pipe. According to the device, when the hydraulic oil is continuously introduced into the oil filling cavity through the oil pipeline, the lifting table and the oil filling shell can be pushed to move upwards until the end part of the sounding pipe abuts against the elastic gasket in a sealed mode. Compared with the prior art, welding operation is not needed, the workload is reduced, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the field of performance detection of acoustic measuring tubes for concrete pouring piles, and more specifically relates to a device and method for detecting the sealing and pressure resistance performance of acoustic measuring tubes for pouring piles. Background technique [0002] The steel thin-walled acoustic tube for concrete pouring piles is an indispensable acoustic detection tube. The integrity of a pile body can be detected by using the acoustic tube. aisle. It is an important part of the ultrasonic testing system for cast-in-situ piles. Its pre-embedded method in the pile and its layout on the cross-section of the pile will directly affect the testing results. [0003] The sealing and pressure resistance performance of the acoustic tube itself is particularly important for the subsequent ultrasonic testing of cast-in-place piles, which will directly affect the accuracy of ultrasonic testing results of cast-in-place pi...
