Description

The ultrasound examination pipe

Technical field

The utility model relates to a kind of ultrasound examination pipe, belongs to building field, is used for building, bridge construction detection concrete spouting quality of pile.

Background technology

In order to detect the concrete spouting quality of pile, whether qualified as correlated qualities such as stake tomography, honeycomb, segregation, cross dimensionss, usually detect with supersonic reflectoscope, it need be provided with preformed hole in the elongated direction of concrete-pile, so that utilize the ultrasound examination probe to detect the actual cast molding situation of stake by whole preformed hole, promptly adopt pre-buried common welded tube, after concrete depositing, form preformed hole.This welded tube just is known as the ultrasound examination pipe after pre-buried.When the dark common welded tube 6m that surpasses on the open market of stake grew, welded tube adopts the mode of welding to connect usually, and was long to reach stake.This pre-pipe laying (detector tube) requires to possess certain watertight, must stop concrete in the inflow pipe, to cause the ultrasound examination probe to pass through otherwise pipeline can be blocked by concrete under certain pressure.Because detector tube is the purpose as preformed hole, usually not as strength member, so adopt as long as hard to bear this concrete pressure in maximum depths of energy is just passable.At present the way of construction work is: with common welded tube transferring along with concrete reinforcing cage at the scene, connect by root bead, the equipment that adopts is arc-welding machine normally, require weldment (detector tube) that certain wall thickness is arranged, usually greater than 3mm, otherwise weldment (detector tube) can be punctured to become lead to the hole and cause the plugging phenomenon takes place behind the spillage by electric current, and two joints are typically provided with the joint sleeve that an about 10cm grows, and is beneficial to welding.Engineering site welds (circumferential weld vertical position welding) about 15 minutes of joint time usually, according to 4 detector tube 45cm (8 joints of common welded tube 9 joints that need 6m) dark calculating of stake, then needs to weld 4 * 8=32 root joint, total spended time 32 * 15=470 minute.For bored concrete pile, behind the clear hole before the deposit concrete, one minute the danger of hole wall collapse at most that postpones one fen clock time.Therefore, the method waste material of above-mentioned site welding, the stake hole wall caves in easily, and pore is stopped up by concrete easily, is difficult to guarantee the construction quality of concrete-pile.

Chinese patent CN2841771Y discloses a kind of ultrasound examination pipe, be connected into a longer pipe body by the more piece hollow tubular and second hollow tubular along axis direction, end face joint at per two hollow tubulars is provided with the connection packoff, described connection packoff is provided with waney splice sleeve and flexible seal ring, the shortcoming of this structure is to connect the sealing device structure complexity, install also inconvenient, particularly still to splice sleeve be welded to the termination of steel hollow tubular with seam welder, just site operation still needs welding, and the engineering time is still longer.

Summary of the invention

The purpose of this utility model provides and a kind ofly can not only improve installation effectiveness and quality, reduces construction cost, and ultrasound examination pipe simple in structure, easy construction.

The technical scheme that realizes above-mentioned purpose is: a kind of ultrasound examination pipe, form along the axis connection by bottom tube, push pipe and at least one hollow connecting pipe, bottom tube and push pipe are the blind hole pipe of an end opening, one end of connecting pipe is provided with internal thread, the other end is provided with external thread, the openend of bottom tube is threaded with connecting pipe, and on the internal thread of the junction of bottom tube and connecting pipe, be set with O-ring seal, the openend of push pipe is threaded with connecting pipe, and is set with O-ring seal on the internal thread of the junction of push pipe and connecting pipe.

Further, hollow connecting pipe adopts the quantity more than two or two, also by being threaded, and is set with O-ring seal on the internal thread of its junction between the connecting pipe.

The outer wall of connecting pipe is provided with driving hole.

After adopting technique scheme, the openend of bottom tube is threaded with connecting pipe, the openend of push pipe is threaded with connecting pipe, is connected between connecting pipe and the connecting pipe also to adopt to be threaded, thereby does not on-the-spotly need welding when connecting the ultrasound examination pipe, only need spin, it is very convenient to construct, and does not need the professional, has shortened the field erected time greatly, improve installation effectiveness and quality, also reduced the cost of construction.Simultaneously, the junction of bottom tube and connecting pipe, connecting pipe and connecting pipe and connecting pipe and push pipe all is provided with O-ring seal, and there is weld defects such as trachoma the commissure and is difficult for checking and causes airtight performance to descend the phenomenon of spillage plugging to occur when having avoided site welding.
