Abstract

The invention discloses a plastic steel coated type ultrasonic detection pipe for a bridge foundation pile, and belongs to the technical field of auxiliary equipment for buildings. The plastic steel coated type ultrasonic detection pipe comprises a bottom pipe with a sealing cover at the bottom end, at least one hollow middle pipe, a top pipe and a top cover, wherein a first pipe sleeve is additionally arranged on the outer wall of the top pipe; a second pipe sleeve is additionally arranged on the outer wall of the bottom pipe; one end of the middle pipe is hermetically connected with that of the top pipe; the other end of the middle pipe is hermetically connected with the opening end of the bottom pipe; and the top cover is arranged at the other end of the top pipe. The plastic steel coated type ultrasonic detection pipe has the advantages as follows: the ultrasonic detection pipe has the strength of a steel pipe and corrosion resistance and wear resistance of a plastic pipe, and the sealing performance of the whole pipeline is guaranteed as the plastic pipe with a coating layer adopts a seamless structure; as the pipe wall of the integrated detection pipe coated with a plastic layer is thicker, the detection pipe is not easily damaged by a guide pipe so as to avoid slurry leakage, and the detection pipe is quick and convenient for field construction installation due to the adoption of non-welding connection; and the specific gravity of plastic is small, so that a compound pipe of the plastic and the steel pipe with the same wall thickness is low in cost and safer and more reliable to use.

Description

Plastic-steel application type type ultrasonic testing tube for Bridge Piles

Technical field

the present invention relates to a kind of type ultrasonic testing tube, be specifically related to a kind of in the bridge construction process for detection of plastic-steel application type type ultrasonic testing tube for the Bridge Piles of pile quality, belong to utility appliance technical field for building.

Background technology

whether qualified in order to detect the bridge concrete piling quality, usually adopt supersonic reflectoscope to detect, it need to arrange preformed hole on concrete-pile stake length direction, in order to utilize ultrasonic detecting probe to carry out the actual moulding by casting situation of detection of pier foundation by whole preformed hole, adopt pre-buried common welded tube, form preformed hole after pouring concrete, this welded tube just is known as type ultrasonic testing tube after pre-buried.Type ultrasonic testing tube is the passage that bridge concrete bored concrete pile carry out ultrasonic Detection Method time probe enters pile body inside, it is the important component part of bored concrete pile ultrasonic testing system, and its pre-buried mode and arrangement form on the xsect of stake thereof in stake will directly affect testing result.Therefore the selection of type ultrasonic testing tube material, the entrant sound rate of take is large, be convenient to install and cost hangs down as principle.

at present, domestic common Bridge Piles detector tube mainly contains two kinds of versions: a kind of is to adopt the ratio-frequency welded tube that diameter 50～60mm and wall thickness are 3～3.5mm, thickness of pipe due to steel pipe, material cost is high, in work progress, needs to adopt the mode of welding to connect, not only complex operation, production efficiency is low, can cause a large amount of man power and materials' waste, and connection reliability is poor, uses dangerous.Another kind is to adopt the detector tube of exempting from welding connecting mode, its wall thickness is below 1.5mm, very convenient in installing and using, also both economical practicality, but this thin-wall steel tube is intensity and poor reliability in actual applications; thin-walled welding pipe easily ftractures in joint, easily by the tremie in grout, crashed through even fracture after cracking, thereby cause the spillage phenomenon.

in view of above-mentioned prior art, be necessary existing Bridge Piles is improved with the ultrasound examination tubular construction, technical scheme described below produces under this background.

Summary of the invention

task of the present invention be to provide a kind of simple in structure, easy for installation, connect reliable, intensity is high, not only ensure the quality of products but also save the plastic-steel application type type ultrasonic testing tube for Bridge Piles of cost and good seal performance.

task of the present invention is achieved like this, plastic-steel application type type ultrasonic testing tube for a kind of Bridge Piles, comprise that a bottom has the bottom tube of capping, at least one hollow middle pipe, push pipe and top cover, is characterized in: have additional the first pipe box that adopts high density polyethylene to make on the outer wall of described push pipe, have additional equally the second pipe box that adopts high density polyethylene to make on the outer wall of described bottom tube, one end of described middle pipe is connected with an end of described push pipe, be formed with at least one pair of and extend out the first seal groove of establishing to tube wall on an end of middle pipe, between a pair of the first seal groove, be formed with for the first indent for the hydraulic tool crimping, be provided with in a pair of the first seal groove for the end outer wall with push pipe and form the first O-ring seal be tightly connected, the other end of described middle pipe is connected with the openend of described bottom tube, be formed with at least one pair of and extend out the second seal groove of establishing to tube wall on the other end of middle pipe, between a pair of the second seal groove, be formed with for the second indent for the hydraulic tool crimping, be provided with in a pair of the second seal groove for the openend outer wall with bottom tube and form the second O-ring seal be tightly connected, be provided with top cover on the other end of described push pipe.

in a specific embodiment of the present invention, the wall thickness of described push pipe and bottom tube is 1～1.5mm, and the wall thickness of described the first pipe box, the second pipe box is 1.5～2mm.

in another specific embodiment of the present invention, described the first pipe box, the second pipe box adopt the mode of extrusion moulding to be coated in respectively on the outer wall of described push pipe, bottom tube.

in another specific embodiment of the present invention, the quantity of described middle pipe is one or more, and between adjacent middle pipe, the same mode of crimping that adopts connects.

after the present invention adopts said structure, the beneficial effect had: at first, due to first, second pipe box that has additional plastics on the outer wall at push pipe, bottom tube and make, the intensity that had both there is steel pipe, corrosion-resistant, mar proof that plastic tube is arranged again, because the coat plastic tube is jointless structure, thereby guaranteed the sealing property of whole pipeline, and plastics also has very high intensity; Secondly, because the whole detection tube wall that is coated with plastic layer is thicker, therefore be difficult for being broken and causing spillage by conduit, and each detector tube adopts and exempt from the soldered mode that connects, make site operation quick for installation, convenient; The 3rd, due to the light specific gravity of plastics, make the compound tubing cost of the plastics of identical wall thickness and steel pipe low, more more economical than existing thick walled steel tube sound detecting pipe, use safety and reliability.
