Description
La présente invention est un système de contrôle de battage des pieux (SCBP) de fondations.
Le système de contrôle de battage dédié au contrôle de l'enfoncement d'un pieu dans le sol est caractérisé en ce qu'il est composé d’une tête de mesure instrumentalisée reliée à une commande à distance informatique (CAD) permettant d'apprécier en continu la portance du sol où l'on enfonce ledit pieu.
Afin de réaliser les fondations d'une construction, il est possible d’avoir recours à des pieux que l'on enfonce jusqu'à ce que le frottement suffise à reprendre les charges.
Ces pieux sont généralement en acier et mis en place par battage.The present invention is a pile driving control system (SCBP) for foundations.
The pile driving control system dedicated to controlling the sinking of a pile into the ground is characterized in that it is composed of an instrumented measuring head connected to a computer remote control (CAD) making it possible to assess continuously the bearing capacity of the ground where said pile is driven.
In order to make the foundations of a construction, it is possible to use piles that are driven in until the friction is sufficient to take up the loads.
These piles are usually made of steel and driven in place.
Les techniques de pose de pieux actuelles consistent à frapper les-dis pieux au moyen d’un batteur diesel, hydraulique ou pneumatiques.
Après une étude de sol réalisé par sondage en quelques points du terrain généralement carottage et analyse des couches voir par pressiomètrie, le contrôle de portance se fait soit en fonction de la longueur d’enfoncement calculée en fonction des diverses couches révélées, soit visuellement lorsque le pieux ne s’enfonce plus (refus).
Cette méthode est relativement empirique puisqu’il faudrait, pour être rigoureux, faire un sondage de sol pour chaque pieu afin d’adapter sa longueur. Mais les forages coutent bien trop cher quand il s’agit de fondations pour des habitations individuelles ou des petits ensembles.
L'une des conséquences en est que la technique des pieux n’est pas beaucoup utilisée et par précaution, quand elle est utilisée on tend à allonger la longueur des pieux ce qui induit des surcoûts inutiles.
Il existe des méthodes de vérifications de portance après enfoncement, mais ces essais n’ont pas de réalité économique pour de petites constructions ce qui pousse les constructeurs à rester sur les fondations dites traditionnelles en béton.Current pile-laying techniques consist of hitting the piles using a diesel, hydraulic or pneumatic drummer.
After a soil study carried out by sounding at a few points on the ground, generally coring and analysis of the layers or even by pressuremeter, the lift control is done either according to the length of depression calculated according to the various layers revealed, or visually when the piles no longer sink (refusal).
This method is relatively empirical since it would be necessary, to be rigorous, to make a soil survey for each pile in order to adapt its length. But drilling is far too expensive when it comes to foundations for individual houses or small groups.
One of the consequences is that the pile technique is not widely used and as a precaution, when it is used, the length of the piles tends to be lengthened, which induces unnecessary additional costs.
There are methods for checking bearing capacity after driving in, but these tests have no economic reality for small constructions, which pushes builders to stay on so-called traditional concrete foundations.
