Description

Fluid pressure type ultrasound examination pipe

Technical field

The utility model relates to a kind of fluid pressure type ultrasound examination pipe, and the quality that be used for building, bridge construction detects cast-in-place concrete pile belongs to technical field of buildings.

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 at the length direction of concrete-pile, so that utilize the ultrasound examination probe to detect the actual moulding by casting situation of pile foundation by preformed hole, promptly adopt pre-buried welded tube, after concrete depositing, form preformed hole.This welded tube just is known as the ultrasound examination pipe after pre-buried.

At present, the version of the ultrasound examination pipe that occurs on the market mainly contains two kinds: a kind of is spiral ultrasound examination pipe, it comprises bottom tube, the segmentum intercalaris adapter in several of sealing a bottom, push pipe and is used for cooperating with push pipe and mat plays the top cover of cap seal effect, described bottom tube with between joint is taken over, each joint take between and joint topmost take over push pipe between be connected to be and be threaded.The deficiency that this spiral ultrasound examination pipe exists is: require adjacent 2-section pipe body to remain on linear position when connecting, and difficulty realization in the practice of construction process causes the butt joint thread to be difficult to be screwed to the position, poor sealing performance.Another kind is a flange form ultrasound examination pipe, it comprises bottom tube, the segmentum intercalaris adapter in several of sealing a bottom, push pipe and is used for cooperating with push pipe and mat plays the top cover of cap seal effect, described bottom tube with between joint is taken over, each joint take between and joint topmost take over push pipe between the flange butt joint back that the expansion by separately is located on the body that is connected connect with bolt and nut, and at adjacent 2-section pipe interface with the sealing of O RunddichtringO.This flange form ultrasound examination pipe, the detector tube external diameter after the connection is bigger, and easy and tremie collision causes detector tube distortion, distortion, causes detection probe to pass through smoothly; Simultaneously, sealing is relatively poor, and mortar infiltrates easily, stops up detector tube, can't detect.The common defects that above-mentioned two kinds of structures also exist is: the scene can't be according to actual stake long and steel reinforcement cage freely change the length of detector tube tube coupling, cause the waste of detector tube material.

Summary of the invention

At above-mentioned existing problems, the purpose of this utility model is that a kind of good airproof performance will be provided, and is simple to operate, easy for installation, and save time, the fluid pressure type ultrasound examination pipe of laborsaving, material-saving.

The purpose of this utility model reaches like this, and a kind of fluid pressure type ultrasound examination pipe comprises the bottom tube 4 that seals a bottom, at least one hollow middle pipe 3, push pipe 2 and top cover 1, is characterized in; On the openend of described bottom tube 4, be formed with at least one pair of and extend out second seal groove of establishing 41 to tube wall, between a pair of second seal groove 41, be formed with second indent 42 that is used for the crimping of feed flow press tool, in described a pair of second seal groove 41, be provided with one second pair of O RunddichtringO 43, the outside of described second pair of O RunddichtringO 43 is formed with a pair of second boss 431 that cooperates with second seal groove 41 of being used for, and is formed with secondary sealing area 432 in the inboard of described second pair of O RunddichtringO 43; In described a pipe end of 3 insert in the openend of bottom tube 4 and and the secondary sealing area 432 of second pair of O RunddichtringO 43 inboard between constitute and be tightly connected, be formed with at least one pair of on the other end of pipe 3 in described and extend out first seal groove of establishing 31 to tube wall, between a pair of first seal groove 31, be formed with first indent 32 that is used for the crimping of feed flow press tool, in described a pair of first seal groove 31, be provided with one first pair of O RunddichtringO 33, the outside of described first pair of O RunddichtringO 33 is formed with a pair of first boss 331 that cooperates with first seal groove 31 of being used for, and is formed with primary sealing area 332 in the inboard of described first pair of O RunddichtringO 33; During one end of described push pipe 2 inserts in the other end of pipe 3 and and the primary sealing area 332 of first pair of O RunddichtringO 33 inboard between constitute and be tightly connected, the other end of described push pipe 2 is provided with top cover 1.

In an embodiment of the present utility model, the quantity that described middle pipe 3 adopts more than two or two are also passed through the hydraulic tool crimping between the middle pipe 3, and two O RunddichtringOs are set in the seal groove of junction.

In another embodiment of the present utility model, the two ends of described middle pipe 3 all can be formed with seal groove and be used for the indent of feed flow press tool crimping, and two O RunddichtringOs are set in the seal groove of junction.

The utility model is because after adopting said structure, the beneficial effect that has: sealing property excellence; When using this product, can avoid site welding, mantle fiber or slot rolling operation fully, it is auxiliary to need not electric power, only needs to adopt supporting hydraulic tool get final product as the envelope pressing tongs, and manual operation can easily be finished, and save time, laborsaving, material-saving, and one-step installation is successful.
