As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The embodiments of the utility model will be described in further detail below with reference to the accompanying drawings:

because the butt joint mode of two present pipes all is hot melt butt joint, or simple threaded connection again, the first defect of this kind of mode is that the dismouting is time-consuming, and the defect of second is that the leakproofness is not high, therefore the demand of connector 4 is higher relatively. Therefore, the present invention designs the connector 4, the concrete structure of which is shown in fig. 2, and includes a first member and a second member, since the field of application of the present invention is acoustic pipe, in order to detect whether the quality of the bridge concrete cast-in-place pile is qualified, an ultrasonic detector is usually used for detecting, it needs to set a reserved hole in the pile length direction, so as to detect the actual casting forming condition of the concrete pile through the whole reserved hole by using an ultrasonic detecting probe, therefore, one end of the first member and the second member are both provided with an opening (the first member and the second member are both single acoustic single pipe 1), and further includes a connector assembly, the connector assembly includes a fixed sleeve 41, a guide sleeve 42 and a screwing sleeve 43, the fixed sleeve 41 is sleeved on the opening of the first member, the guide sleeve 42 includes a guide portion 421 and a fixing portion 422, the fixing portion 422 is sleeved on the opening of the second member, the screwing sleeve 43 is movably sleeved on the second member, when the first member is mated with the second member, the fixing sleeve 41 is sleeved on the outer surface of the guiding portion 421, and the tightening sleeve 43 is screwed on the fixing sleeve 41 to prevent the guiding portion 421 from separating from the fixing sleeve 41.

Because the present domestic existing bridge pile foundation detection pipe adopts the following three kinds of condition: 1. the high-frequency welded pipe with the wall thickness of 3.0-3.5mm and the outer diameter of 50-60mm is connected in a welding or threaded mode, so that the construction process is inconvenient, the efficiency is low, and a large amount of manpower and material resources are wasted; 2. the thin-wall steel pipe (the wall thickness is less than 1.5 mm) which adopts a welding-free form is very convenient in the installation and use process and is more economical and practical, but the thin-wall steel pipe has poor reliability in practical application and is easy to be broken and cracked by a concrete conduit of a poured hole so as to cause slurry leakage; many problems occur in the using process of high-speed iron pile bases such as Jinghuso, Shanghan and the like, and the thin-wall pipe is stopped at the later stage; 3. the acoustic pipe is connected by adopting the connector 4, and in order to ensure that the connection is fast and fast, the existing connector 4 has a complex structure and high manufacturing cost; therefore, the high-strength plastic sound-measuring tube is designed, the specific structure of which is shown in fig. 2, and comprises at least two sound-measuring single tubes 1 (the sound-measuring single tubes 1 are spliced with each other in pairs), two adjacent sound-measuring single tubes 1 are spliced with each other through clamping and/or threads to form a sound-measuring main tube 2, the sound-measuring single tubes 1 are all metal tubes which are spliced into the sound-measuring main tube 2 through auxiliary sleeving of a hydraulic device, the splicing mode is difficult to assemble and disassemble, the two sound-measuring single tubes 1 can be connected with each other in a clamping mode or in a threaded mode, and can be connected together in a clamping mode and in a threaded mode, so that the connection is more stable.
