  Un nouveau dispositif d'assemblage de tubes de sondage 
Le but de la présente invention est d'obtenir un rac- cord de tuoes de sondage, solide, facile à visser, s'appli- ouant à des tubes de peu d'épaisseur et, conséquemment, légers. 



   Le dessin ci-joint donnant une coupe du dispositif en montre suffisamment la constitution. 



   Un des tubes D est embouti à son extrémité, d'une quan- tité suffisante pour recevoir le bout F d'un manchon B, que l'on soude en E, à la soudure autogène, au tube D. Ce man- chon B porte, intérieurement, un pas de vis de profil quel- conque, solide, de manière à constituer le bout femelle de l'assemblage. 



   Au tube C, qui doit faire suite au tube D, on adapte, de la même manière, un manchon A dont la partie G s'emboite dans le bout embouti du tube C et auquel il est également soudé à la soudure autogène en H. 

 <Desc/Clms Page number 2> 

 



   Ce manchon porte, extérieurement, un filet de vis corres pondant à celui du manchon B, de manière à constituer le oout mâle de l'assemblage 
Les deux tubes étant ainsi constitués, il est facile de les visser l'un sur l'autre pour continuer la formation de la colonne de tubes. 



   On remarquera que ce dispositif donne des avantages multiples et importants : 
Il permet l'emploi de tubes d'acier de faible épaisseur conséquemment légers pour le transport et pour la facilité de manoeuvre. 



   Le pas de vis peut être d'un profil assez profond, solide, d'emboîtement facile, sans préjudice pour la solidité de l'assemblage, étant donné l'épaisseur sérieuse conservée aux deux manchons derrière le filet de vis. 



   L'ensemble de l'assemblage conserve un diamètre inté rieur uniforme, de manière à ne gêner en rien la liberté d'ac tion des outils de   perf orat ion.   



   D'autre part, la paroi extérieure ne présente aucune aspérité pouvant former accrochage. 



   Les manchons A et B pourraient se souder directement aux tubes C et D sans posséder les bouts renflés G et F, mais ce dispositif n'est pas à conseiller car cela constituerait une cause très sérieuse de faiblesse. 



   Ce dispositif permet l'emploi de tubes du commerce, re- lativement peu coûteux, et donne lieu à un prix de revient d'usinage également peu élevé.

  A new device for assembling sounding tubes
The object of the present invention is to obtain a connection of sounding tubes, strong, easy to screw, applying to tubes of little thickness and, consequently, light.



   The attached drawing giving a section of the device sufficiently shows its constitution.



   One of the tubes D is pressed at its end, of a sufficient quantity to receive the end F of a sleeve B, which is welded in E, with autogenous welding, to the tube D. This sleeve B carries, internally, a thread of any profile, solid, so as to constitute the female end of the assembly.



   To tube C, which must follow on from tube D, a sleeve A is fitted in the same way, part G of which fits into the stamped end of tube C and to which it is also welded to the autogenous H weld.

 <Desc / Clms Page number 2>

 



   This sleeve carries, on the outside, a screw thread corresponding to that of the sleeve B, so as to constitute the male oout of the assembly
The two tubes being thus constituted, it is easy to screw them one on the other to continue the formation of the column of tubes.



   It will be noted that this device gives multiple and important advantages:
It allows the use of thin steel tubes which are consequently light for transport and for ease of handling.



   The thread can be of a fairly deep profile, solid, easy to fit, without prejudice to the solidity of the assembly, given the serious thickness retained at the two sleeves behind the screw thread.



   The whole assembly maintains a uniform internal diameter, so as not to hinder the freedom of action of the perf orat ion tools.



   On the other hand, the outer wall has no roughness that can form a catch.



   The sleeves A and B could be welded directly to the tubes C and D without having the swollen ends G and F, but this device is not advisable because this would constitute a very serious cause of weakness.



   This device allows the use of commercially available tubes, relatively inexpensive, and gives rise to a cost of machining which is also low.


    

Claims (1)

REVENDICATION. CLAIM. Un dispositif d'assemblage de tubes de sondage consis- tant à sonder sur le bout d'un des tubes, un manchon fi- leté intérieurement formant bout femelle de l'assemblage et sur le bout de l'autre tube, un manchon fileté extérieu- <Desc/Clms Page number 3> rement formant le bout mâle de l'assemblage, les diamètres de ces manchons étant tels que, tout en conservant le dia- mètre uniforme intérieur de la colonne, les manchons conservent derrière leurs filets de vis une épaisseur égale à celle des tubes, comme montré au dessin et donnant les avantages énoncés. A probing tube assembly device consisting of probing on the end of one of the tubes, an internally threaded sleeve forming the female end of the assembly and on the end of the other tube, an external threaded sleeve - <Desc / Clms Page number 3> rement forming the male end of the assembly, the diameters of these sleeves being such that, while maintaining the uniform diameter inside the column, the sleeves retain behind their screw threads a thickness equal to that of the tubes, as shown to the drawing and giving the stated advantages.
