Description
Technical field
The utility model relates to a kind of novel excusing from death ripple detector tube, 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 excusing from death ripple detection 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 excusing from death ripple detector tube, 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.
Chinese patent CN201130118Y discloses a kind of ultrasound examination pipe, being connected to of push pipe and connecting pipe is threaded, connecting pipe is connected also for being threaded with bottom tube, though connected mode has had very big progress, but still exist not enough, the i.e. essential rotation of connecting pipe and push pipe in connection procedure when the ultrasound wave connecting pipe is longer, has brought inconvenience to construction.
Summary of the invention
The purpose of this utility model provides and a kind ofly can improve operating efficiency and quality, the new type ultrasonic detector tube of good seal performance.
The technical scheme that realizes above-mentioned purpose is: a kind of new type ultrasonic detector tube, by bottom tube, push pipe and at least one hollow connecting pipe form along the axis connection, bottom tube and push pipe are the blind hole pipe of an end opening, the openend of push pipe is inserted in the top of connecting pipe, and the inwall with the push pipe matching part of connecting pipe is provided with groove, be provided with O-ring seal in this groove, be fixed with the external thread circle on the upper end outer wall of connecting pipe, the bottom outer wall of push pipe is provided with protrusion, be set with external thread circle nut engaged on this protrusion, peg graft in the openend of bottom tube and the lower end of connecting pipe, and the inwall with the connecting pipe matching part of bottom tube is provided with groove, be provided with O-ring seal in this groove, be fixed with the external thread circle on the upper end outer wall of bottom tube, the bottom outer wall of connecting pipe is provided with protrusion, is set with on this protrusion and external thread circle nut engaged.
Further, the protrusion of push pipe below is provided with O-ring seal.
Further, the protrusion of connecting pipe below is provided with O-ring seal.
After adopting technique scheme, be fixed with the external thread circle on the upper end outer wall of connecting pipe, the bottom outer wall of push pipe is provided with protrusion, be set with external thread circle nut engaged on this protrusion, after being plugged on connecting pipe and push pipe together, as long as screwing nut just can connect connecting pipe and push pipe, need not to revolve push pipe and connecting pipe, it is very convenient to construct, improved operating efficiency,, be provided with O-ring seal in this groove because the inwall with the push pipe matching part of connecting pipe is provided with groove, thereby the junction good seal performance of connecting pipe and push pipe, improved construction quality.Be fixed with the external thread circle on the upper end outer wall of bottom tube, the bottom outer wall of connecting pipe is provided with protrusion, be set with on this protrusion and external thread circle nut engaged, connecting pipe is after bottom tube is plugged on, as long as screwing nut just can connect bottom tube and connecting pipe, need not to revolve bottom tube and connecting pipe, bring facility to construction, simultaneously, because the inwall with the connecting pipe matching part of bottom tube is provided with groove, be provided with O-ring seal in this groove, thereby the good seal performance of the junction of bottom tube and connecting pipe, help improving construction quality.
