Abstract

The invention relates to watertight claw couplings (14) for sheet piling comprising at least one housing (30) inside one of the claws (14) and in which at least one seal (18) is located. <IMAGE>

Description

Les parois de palplanches sont assemblées à partir d'une pluralité de profilés en aciers qui sont reliés les uns aux autres par des griffes d'enclenchement. Ces griffes d'enclenchement présentent un certain jeu afin de permettre un glissement des griffes, l'une dans l'autre, lors de l'assemblage de la paroi de palplanches. A cause de cette tolérance, les griffes des palplanches ne sont étanches que sous certaines conditions.The sheet pile walls are assembled from of a plurality of steel profiles which are connected to each other by interlocking claws. These claws have a certain amount of play to allow a sliding of the claws, one inside the other, during the assembly of the sheet pile wall. Because of this tolerance, the sheet pile claws are only waterproof under certain conditions.

Du moment qu'on requiert pour la paroi de palplanches une étanchéité, qu'elle soit complète ou qu'elle soit la plus poussée possible, il faut prévoir des mesures supplémentaires d'étanchéité pour les griffes.As long as the sheet pile wall is required a seal, whether it is complete or whether it is the as far as possible, measures must be planned additional sealing for the claws.

On a essayé de rendre les parois de palplanches étanches, comme décrit dans la demande de brevet publiée allemande DE-OS-21 42 957, en injectant, sur le chantier même, avant le battage des palplanches, dans une griffe de ces dernières, une masse qui est appliquée à l'état liquide et qui se solidifie sous forme de mousse à consistance élastique. Alternativement on peut se conformer à la demande de brevet allemande, délivrée et publiée, DE-AS-27 22 978, selon laquelle on constitue un joint résistant au cisaillement, dans la griffe à enfiler, en y injectant un produit approprié, en égalisant ce produit au moyen d'un dispositif mobile tout en lui conférant ainsi la forme désirée. Comme ces joints sont très sensibles, les palplanches ne peuvent être enfoncées que par battage et non par vibration. Dans le brevet allemand DE-PS-38 15 236-C2 on décrit un procédé qui peut être mis en oeuvre sur le chantier et qui est exécuté comme suit : avant l'enfoncement d'un élément de palplanche on introduit une colle dans la griffe non enclenchée, on obture la chambre de cette partie de la griffe avec un élément de calibrage pour protéger la colle et pour éviter la pénétration de terre dans la griffe et, une fois la profondeur d'enfoncement voulue atteinte, on retire l'élément de calibrage après le battage.We tried to make the sheet pile walls waterproof, as described in the published patent application German DE-OS-21 42 957, injecting, on site even, before the pile driving, in a claw of the latter, a mass which is applied in the liquid state and which solidifies in the form of consistency foam elastic. Alternatively we can comply with the German patent application, issued and published, DE-AS-27 22 978, according to which a joint is formed shear resistant, in the feed dog, in injecting an appropriate product, equalizing this product with means of a mobile device while thus giving it the desired shape. As these joints are very sensitive, sheet piles can only be driven in by threshing and not by vibration. In the German patent DE-PS-38 15 236-C2 describes a process which can be implemented implemented on site and which is executed as follows: before the insertion of a sheet pile element we introduce an adhesive in the claw not engaged, we close the chamber of this part of the claw with an element of calibration to protect the glue and to avoid penetration of soil into the claw and, once the desired depth of penetration, remove the calibration element after the hype.

Suivant la demande de brevet publiée allemande DE-OS-27 00 414, on applique un joint d'étanchéité contre celle des faces de la griffe sur laquelle on s'attend à voir agir une surpression ou une autre influence comparable.According to the German published patent application DE-OS-27 00 414, we apply a seal against that of the claw faces on which we expect see an overpressure or other comparable influence act.

Les procédés mentionnés ci-dessus ont le désavantage que le joint d'étanchéité ne présente finalement que très peu de résistance au cisaillement. Lors de l'enfoncement des palplanches, que ce soit par battage ou par vibrations, les griffes frottent l'une contre l'autre et les joints d'étanchéité sont détruits, partiellement du moins, par rabotage du joint.The above mentioned methods have the disadvantage that the seal ultimately exhibits very little shear strength. During driving the sheet piles, either by threshing or by vibration, the claws rub against each other and the seals are destroyed, partially at least, by planing the joint.

La demande de brevet européen EP 0 264 527 décrit un système de griffes étanches pour des parois moulées en matière plastique qui sont introduites dans une fente aménagée dans la terre et qui a été remplie au préalable par du bentonite. Les griffes pour ces parois moulées comprennent des rainures dans lesquelles un joint d'étanchéité a été placé avant l'enclenchement des griffes.European patent application EP 0 264 527 describes a system of claws watertight for molded plastic walls which are introduced into a slot in the ground which has been previously filled with bentonite. The claws for these diaphragm walls include grooves in which a seal was placed before engaging the claws.

Le but de la présente invention est de procurer des griffes de palplanches munies d'un joint d'étanchement résistant au rabotage lors de l'enfilement des griffes.The object of the present invention is to provide sheet pile claws fitted with a planing-resistant seal when threading the claws.

La solution conforme à la présente invention çonsiste en une griffe étanche pour palplanches caractérisé par au moins une rainure située à l'intérieur de la griffe et dans laquelle au moins un joint d'étanchéité est logé.The solution according to the present invention is in a waterproof claw for sheet piles characterized by at least one groove located inside the claw and in which at least one seal is housed.

Un des avantages principaux de la présente invention est que le joint est situé à l'intérieur d'une rainure. Il est donc protégé contre le cisaillement et le rabotage lors de l'enfilement des griffes de palplanches.One of the main advantages of the present invention is that the seal is located at inside a groove. It is therefore protected against shearing and planing when threading the sheet pile claws.

Selon un premier mode de réalisation avantageux, le joint utilisé est en un matériau gonflable ou expansible.According to a first advantageous embodiment, the seal used is in one inflatable or expandable material.

Un des avantages d'un joint gonflable ou expansible situé à l'intérieur d'une rainure est qu'après la mise en place de la paroi de palplanches, le joint, en se dilatant ou en se gonflant, se presse fortement contre la paroi opposée et améliore ainsi l'étanchéité de la griffe. Ce joint peut être appliqué à l'usine de fabrication des palplanches ou bien sur le chantier avant l'enfilement des palplanches. One of the advantages of an inflatable or expandable seal located inside a groove is that after the installation of the sheet pile wall, the joint, in expanding or swelling, presses strongly against the opposite wall and thus improves the seal of the claw. This seal can be applied at the factory sheet pile production or on the site before threading sheet piles.

Selon un autre mode de réalisation, le joint utilisé est sous forme d'une bande, de préférence en un matériau élastique tel que du caoutchouc. Le joint utilisé peut aussi être en un matériau pâteux. En principe tous les joints classiques conviennent.According to another embodiment, the seal used is in the form of a strip, preferably of a material elastic such as rubber. The seal used can also be made of a pasty material. In principle all conventional seals are suitable.

Selon encore un autre mode de réalisation, on prévoit des logements sur les deux côtés adjacents de la griffe. De cette manière, l'épaisseur radiale du joint peut être augmentée et la longueur obstruée que l'eau doit traverser est plus importante. L'étanchéité de la griffe de palplanche est ainsi augmentée.According to yet another embodiment, provision is made housings on the two adjacent sides of the claw. Of this way the radial thickness of the joint can be increased and the length obstructed that the water must cross is more important. The sealing of the claw sheet pile is thus increased.

Préférablement, il est avantageux de prévoir une languette ou un épaississement qui forme une surépaisseur du côté extérieur de la griffe de palplanche. De cette manière, l'épaisseur du matériau formant la griffe ne sera pas plus faible à l'endroit où se trouve la rainure. On évite ainsi la formation d'un point de rupture préférentiel à l'intérieur de la griffe.Preferably, it it is advantageous to provide a tongue or a thickening which forms an extra thickness on the outside sheet pile claw. In this way, the thickness of the material forming the claw will not be weaker at where the groove is. This avoids the formation of a preferential breaking point inside of the claw.

On peut aussi, selon un autre mode de réalisation former une languette ou un épaississement sur un côté à l'intérieur de la griffe. La saillie formée par la languette délimite alors deux logements, un de chaque côté de la languette. La languette protège les joints contre le cisaillement lors de l'enfilement des griffes de palplanches.It is also possible, according to another embodiment form a tongue or thickening on one side to inside the claw. The projection formed by the tongue then delimits two housings, one on each side of the tongue. The tongue protects the seals against shear when threading the claws of sheet piles.

D'autres caractéristiques de l'invention sont décrites, à titre non limitatif, en référence aux dessins annexés dans lesquels :

  • la Figure 1 représente une coupe à travers une paire de griffes de palplanches enclenchées;
  • la Figure 2 représente une coupe à travers une griffe de palplanches selon un premier mode de réalisation préféré;
  • la Figure 3 représente une coupe à travers une griffe de palplanches selon un autre mode de réalisation préféré.
Other characteristics of the invention are described, without implied limitation, with reference to the appended drawings in which:
  • Figure 1 shows a section through a pair of interlocking sheet pile claws;
  • Figure 2 shows a section through a sheet pile claw according to a first preferred embodiment;
  • Figure 3 shows a section through a sheet pile claw according to another preferred embodiment.

La Figure 1 montre une coupe à travers deux palplanches 10, 12 munie d'une griffe 14, 16 chacune qui s'enclenchent. Un joint d'étanchéité 18 est logé à l'intérieur d'une rainure 20, formée dans les griffes 14, 16. Le joint 18 de la griffe 14 est pressé fortement contre la griffe 16 et le joint 18 de la griffe 16 est pressé contre la griffe 14. Aucun liquide ne peut donc passer à travers les griffes des palplanches. Le joint 18 est protégé contre le cisaillement lors de l'enfilage des griffes 14, 16 par la rainure 20 dans laquelle il est logé.Figure 1 shows a section through two sheet piles 10, 12 provided with a claw 14, 16 each which snap into place. A seal 18 is housed at the inside of a groove 20, formed in the claws 14, 16. The seal 18 of the claw 14 is pressed strongly against the claw 16 and the seal 18 of the claw 16 is pressed against scratch 14. No liquid can therefore pass to through the claws of the sheet piles. The seal 18 is protected against shearing when threading claws 14, 16 by the groove 20 in which it is housed.

Une languette 22 se situe sur la même griffe 14 du côté opposé de la rainure 20 de sorte à garantir une épaisseur uniforme de la paroi dans toute la griffe 14. Ainsi on permet d'éviter la formation d'un point de rupture préférentiel à l'intérieur de la griffe.A tongue 22 is located on the same claw 14 on the side opposite the groove 20 so as to guarantee a thickness uniformity of the wall throughout the claw 14. Thus one avoids the formation of a breaking point preferential inside the claw.

La Figure 2 montre un autre mode de réalisation d'une griffe 14 d'une palplanche 10 dans laquelle on a prévu deux rainures 24, 26 sur deux côtés adjacents de la griffe 14. Dans chacun de ces logements se situe dans un joint 28 d'étanchéité. Du côté opposé des rainures 24, 26 sont prévues des languettes 22 de renforcement pour augmenter la stabilité mécanique de la griffe 14.Figure 2 shows another embodiment of a claw 14 of a sheet pile 10 in which two are provided grooves 24, 26 on two adjacent sides of the claw 14. In each of these dwellings there is a joint 28 sealing. On the opposite side of the grooves 24, 26 are provided with reinforcing tabs 22 to increase the mechanical stability of the claw 14.

La Figure 3 montre un autre mode de réalisation préféré. Une palplanche 10 est munie d'une griffe 14 dans laquelle deux logements 30, 32 pour des joints d'étanchéité 34 sont prévus sur un même côté de la griffe. Une languette 36 formant une saillie au milieu d'un côté de la griffe crée deux logements 30 et 32 dans lesquels les joints 34 sont prévus. La languette 36 protège les joints 34 contre le cisaillement et/ou le rabotage lors de l'enfilement des palplanches.Figure 3 shows another embodiment prefer. A sheet pile 10 is provided with a claw 14 in which two housings 30, 32 for seals sealing 34 are provided on the same side of the claw. A tongue 36 forming a projection in the middle of one side of the claw creates two housings 30 and 32 in which the seals 34 are provided. Tab 36 protects seals 34 against shearing and / or planing during threading of sheet piles.
