Definitions
- the invention relates to a method of making a tunnel. paved or coated excavation, where a circular section excavation is dug in the ground at using a suitable device and a covering is placed inside this excavation, the laying of the covering including the introduction of the coating portions one after another, in reduced diameter in the part already covered with the tunnel, and their extension to their location final.
- the invention relates in particular to the production of a coated microtunnel, i.e. a small tunnel diameter among others in the case where human intervention not possible.
- US-A-3,645,102 describes such a method in which coating portions forming part of a ring are introduced into the already coated part of the tunnel.
- the coating portions are kept in the folded position by a cable and released when introduced in the part already coated above and drawn using a cable to their final location.
- a wide opening remains however between the free ends of the portions coating, this opening being completed by one or several ring parts introduced separately, making thus the process impossible to carry out in a microtunnel where human intervention is not possible.
- the object of the invention is to remedy the drawbacks above and to provide a method for carrying out coated excavations, in particular microtunnels, in a simple way in convergent soils located at great depth.
- the portions introduced are tube elements cut along their length which are folded, in compression or in a stable state, so that their free ends cover each other, and which are extended to their final location, either by their own elasticity in case they were kept in compression, either by an appropriate device (for example jacks) in the other case, until they form a closed ring leaving no that a possible opening which can close later by the convergence of the soil.
- a second coating or final coating is applied at inside the tube elements.
- this second coating comprises elements which are pushed through tube elements already in square.
- the elements of the second coating can have a diameter equal, except for tolerances, to the inside diameter of the tube elements in closed end position.
- the second coating can be applied in the form of conventional tube elements which are welded together to form a waterproof coating.
- the second coating or a part thereof can be used to push the last tube elements to install through tube elements already in place.
- the figures relate to the realization of an excavation in the form of a horizontal microtunnel of diameter included between 0.5 and 1.5 m, from a main gallery already existing 16, in a clay soil 1, at great depth.
- an excavation device that is to say a microtunnelier 2 is used consisting of three stations, i.e. an anchor station 3, one pusher station 4 and an excavation station 5.
- the microtunnelier 2 is anchored in the ground 1.
- the excavation station 5 composed of a drilling instrument with global attack is advanced, during digging, using the pushing station 4 provided also hydraulic cylinders.
- the anchor station 3 is released and retracted to excavation station 5, using the cylinders pushing station hydraulics 4. Place necessary for the location of a covering element auxiliary 7 is thus released at the rear of the microtunnelier 2.
- the above procedure is repeated, in starting with a new anchoring of the microtunnelier 2.
- the covering is placed in two stages, i.e. a first stage during which a first coating or auxiliary coating 7, intended to resume during the construction of the tunnel, the ground pressures 1 (of the order of 1 MPa), is put in place and a second step during which a second coating or coating final 8, intended to take up ground pressure 1 long term (of the order of 5 MPa), is implemented.
- the auxiliary coating 7 is formed of tube elements 9, for example made of metal, with a thickness of between 5 and 10 mm, and therefore somewhat elastically deformable, which are cut along their entire length and folded over them same, as shown in Figure 2.
- These elements of tube 9 can be routed, one behind the other, in the folded position, up to their location in pushing them through the tube elements 9 already in place, as shown in Figure 2.
- the tube elements 9 open by their own elasticity and return to their initial position, that is to say the position they had after their sectioning, as shown in Figure 3, leaving thus a longitudinal opening 10.
- Each element of tube 9 is provided on its outer face at the level of the longitudinal section, of a guide 11 formed by a flange curve. The function of this guide is the subject of another paragraph.
- auxiliary covering 7 The installation of the auxiliary covering 7 is carried out from the as follows: a first tube element 9 is put in place in the microtunnel; the following tube elements 9 are previously folded back on themselves and introduced one after the other, as shown in section on the figure 2, from the main gallery 16, as and measure that microtunnelier 2 is excavating.
- the tube elements 9 are thus pushed to the level their location, using a pushing station 13, placed in the main gallery 16.
- the tube elements 9 are made integral by suitable wedging devices.
- the tube elements 9 open by elasticity, as shown in Figure 3, leaving a longitudinal opening 10.
- the aforementioned guide 11 limits the movement of the walls of the tube element 9.
- each tube element 9 is such that an edge of the opening 10 is provided with a V-groove 14 and that the other edge of this same opening 10 has a corresponding end 15 in V, such that shown in detail in Figure 4.
- This waterproof final coating 8 is intended to take up the pressure exerted by the soil 1 in the long term.
- This final coating 8 has an equal outside diameter, at tolerances, to the inside diameter of the coating auxiliary 7 with the tube elements 9 in their position closed.
- the final coating 8 is introduced in the form of elements of tube 12 which are pushed, one after the other, to from main gallery 16, using the station 13. As they are introduced, the tube elements 12 are welded to ensure their sealing.
- the final coating 8 can be used to push towards their location the last tube elements 9.
- the microtunnel is carried out as soon as all the elements of tube 9 are in their place and that all tube elements 12 of the final covering 8 have been introduced.
- excavation need not necessarily be a horizontal microtunnel. It can be a tunnel, a gallery or any horizontal excavation or inclined or even vertical.
- the microtunnelier 2 can according to the case be replaced by another excavation device appropriate.
- the tunnel boring machine or other excavation device can build on the tube elements 9 already in place. So the station anchor 3 can be eliminated or replaced.
- the tube elements 9 of the first coating are folded back into a stable position (and are therefore no longer held in compression) and, instead of opening by their own elasticity, are mechanically extended to their final location, for example by jacks.
- tube elements 9 do not necessarily have to be made of metal. They can for example be in matters synthetic.
- tube elements 12 of the final covering 8 do not need not be metal. They can by example be concrete.
- this final coating 8 may in certain variants be omitted or replaced by concrete injection for example outside around the tube elements 9 of the auxiliary coating 7 installed.

Description
L'invention concerne un procédé de réalisation d'un tunnel revêtu ou d'une excavation revêtue, selon lequel une excavation de section circulaire est creusée dans le sol à l'aide d'un dispositif approprié et un revêtement est placé à l'intérieur de cette excavation, la pose du revêtement comprenant l'introduction des portions de revêtement l'une après l'autre, en diamètre réduit dans la partie déjà revêtue du tunnel, et leur extension à leur emplacement final. The invention relates to a method of making a tunnel. paved or coated excavation, where a circular section excavation is dug in the ground at using a suitable device and a covering is placed inside this excavation, the laying of the covering including the introduction of the coating portions one after another, in reduced diameter in the part already covered with the tunnel, and their extension to their location final.
L'invention concerne en particulier la réalisation d'un microtunnel revêtu, c'est-à-dire un tunnel de petit diamètre entre autre dans le cas où l'intervention humaine n'est pas possible.The invention relates in particular to the production of a coated microtunnel, i.e. a small tunnel diameter among others in the case where human intervention not possible.
Dans un procédé connu sous le nom de "pipe-jacking", des éléments de revêtement sont poussés les uns derrière les autres, à partir d'une chambre de départ, à l'arrière d'un microtunnelier, assurant ainsi son avancement.In a process known as "pipe jacking", covering elements are pushed behind each other others, from a departure room, at the back of a microtunnelier, thus ensuring its advancement.
Si ce procédé est applicable dans certains sols stables, il est parfois impraticable dans d'autres sols qui se tassent ou convergent assez rapidement, tels que des sols argileux. Il est évident que, suite à la convergence, la friction du sol sur les sections du revêtement augmente, au fur et à mesure que le microtunnelier avance. Du fait de l'augmentation de cette friction, des forces de poussée toujours plus grandes sont nécessaires pour faire avancer le tunnelier et les éléments de revêtement déjà introduits ainsi que le microtunnelier. Ces forces peuvent devenir rapidement trop importantes, en particulier à grande profondeur, rendant la construction d'un tunnel d'une longueur supérieure à 30 m irréalisable par cette technique. If this process is applicable in certain stable soils, it is sometimes impractical in other compacting soils or converge fairly quickly, such as clay soils. It is obvious that, following convergence, the friction of the soil on the sections of the coating increases, as as the microtunnelier advances. Because of increased friction, pushing forces ever larger are needed to advance the TBM and the covering elements already introduced as well as the microtunnelier. These forces can become quickly too large, especially large depth, making the construction of a tunnel a length greater than 30 m impractical with this technical.
Un autre procédé, basé sur un dispositif qui maintient sous pression les parois de l'excavation pendant les opérations de creusement, est en cours de développement. L'excavation terminée, le dispositif est retiré et le revêtement final est placé par la méthode de "pipe-jacking". Cette technique, bien qu'originale, requiert une infrastructure lourde et onéreuse. Another method, based on a device which maintains under presses the walls of the excavation during operations excavation is under development. The excavation finished, the device is removed and the final coating is placed by the "pipe-jacking" method. This technical, although original, requires an infrastructure heavy and expensive.
Afin de réduire les forces de frottement à l'interface revêtement-sol, il est déjà connu de mettre en place les portions de revêtement en position repliée au travers de la partie déjà réalisée du tunnel.To reduce friction forces at the interface floor covering, it is already known to install the coating portions in the folded position across the already completed part of the tunnel.
US-A-3.645.102 décrit un tel procédé dans lequel des portions de revêtement formant une partie d'un anneau sont introduites dans la partie déjà revêtue du tunnel. Les portions de revêment sont maintenues en position repliée par un câble et relâchées lorsqu'elles sont introduites dans la partie déjà revêtue susdite et tirées à l'aide d'un câble jusqu'à leur emplacement final. Une ouverture large demeure cependant entre les extrémités libres des portions de revêtement, cette ouverture étant complétée par une ou plusieures parties d'anneau introduites séparément, rendant ainsi le procédé impossible à réaliser dans un microtunnel où l'intervention humaine n'est pas possible.US-A-3,645,102 describes such a method in which coating portions forming part of a ring are introduced into the already coated part of the tunnel. The coating portions are kept in the folded position by a cable and released when introduced in the part already coated above and drawn using a cable to their final location. A wide opening remains however between the free ends of the portions coating, this opening being completed by one or several ring parts introduced separately, making thus the process impossible to carry out in a microtunnel where human intervention is not possible.
L'invention a pour but de remédier aux inconvénients susdits et de procurer un procédé permettant la réalisation d'excavations revêtues, en particulier de microtunnel, d'une manière simple dans des sols convergents situés à grande profondeur.The object of the invention is to remedy the drawbacks above and to provide a method for carrying out coated excavations, in particular microtunnels, in a simple way in convergent soils located at great depth.
Ce but est atteint par le fait que les portions introduites sont des éléments de tube sectionnés sur leur longueur qui sont repliés, en compression ou à l'état stable, de manière à ce que leurs extrémités libres se couvrent, et qui sont étendues à leur emplacement definitif, soit par leur propre élasticité dans le cas où ils étaient maintenus en compression, soit par un dispositif approprié (par exemple des vérins) dans l'autre cas, jusqu'à ce qu'ils forment un anneau fermé ne laissant qu'une ouverture éventuelle qui pourra se fermer plus tard par la convergence du sol. This goal is achieved by the fact that the portions introduced are tube elements cut along their length which are folded, in compression or in a stable state, so that their free ends cover each other, and which are extended to their final location, either by their own elasticity in case they were kept in compression, either by an appropriate device (for example jacks) in the other case, until they form a closed ring leaving no that a possible opening which can close later by the convergence of the soil.
Les avantages obtenus grâce à cette invention consistent essentiellement en ce que les forces de frottement à l'interface revêtement-sol sont éliminées. En effet, le frottement a lieu entre la face intérieure des éléments de tube en place et la face extérieure des nouveaux éléments de tube introduits. La pression exercée par le sol n'influence donc plus les forces de frottement lors du poussage des tubes étant donné que celle-ci est reprise par les éléments de tube extérieurs déjà en place, durant la réalisation de l'excavation. The advantages obtained thanks to this invention consist basically in that the friction forces at the coating-floor interface are eliminated. Indeed, the friction takes place between the inner face of the elements of tube in place and the outside of the new elements of tube introduced. The pressure exerted by the ground therefore no longer influences the friction forces during pushing of the tubes since this is taken up by the external tube elements already in place, during the excavation.
Dans une forme de réalisation particulière de l'invention, après que des éléments de tube soient mis en place, un deuxième revêtement ou revêtment final est mis en place à l'intérieur des éléments de tube. In a particular embodiment of the invention, after tube elements are installed, a second coating or final coating is applied at inside the tube elements.
De préférence, ce deuxième revêtement comprend des éléments qui sont poussés au travers des éléments de tube déjà en place.Preferably, this second coating comprises elements which are pushed through tube elements already in square.
Les éléments du deuxième revêtement peuvent avoir un diamètre égal, aux tolérances près, au diamètre intérieur des éléments de tube en position finale fermée.The elements of the second coating can have a diameter equal, except for tolerances, to the inside diameter of the tube elements in closed end position.
Le deuxième revêtement peut être mis en place sous forme d'éléments de tube classiques qui sont soudés entre eux pour former un revêtement étanche.The second coating can be applied in the form of conventional tube elements which are welded together to form a waterproof coating.
Le deuxième revêtement ou une partie de celui-ci peut être utilisé pour pousser les derniers éléments de tube à installer au travers des éléments de tube déjà en place. The second coating or a part thereof can be used to push the last tube elements to install through tube elements already in place.
D'autres particularités et avantages de l'invention
ressortiront de la description donnée ci-après d'un procédé
pour réaliser une excavation revêtue, selon l'invention.
Cette description n'est donnée qu'à titre d'exemple
non-limitatif en se référant aux dessins annexés, dans
lesquels :
Les figures ont trait à la réalisation d'une excavation
sous forme d'un microtunnel horizontal de diamètre compris
entre 0,5 et 1,5 m, à partir d'une galerie principale déjà
existante 16, dans un sol 1 argileux, à grande profondeur.The figures relate to the realization of an excavation
in the form of a horizontal microtunnel of diameter included
between 0.5 and 1.5 m, from a main gallery already
existing 16, in a
Pour réaliser ce microtunnel, un dispositif d'excavation,
c'est-à-dire un microtunnelier 2 est utilisé constitué de
trois stations, c'est-à-dire une station d'ancrage 3, une
station de poussage 4 et une station d'excavation 5.To make this microtunnel, an excavation device,
that is to say a
A l'aide de la station d'ancrage 3, munie de vérins
hydrauliques 6, le microtunnelier 2 est ancré dans le sol
1. Ensuite, la station d'excavation 5 composée d'un
instrument de forage à attaque globale est avancée, durant
le creusement, à l'aide de la station de poussage 4 munie
également de vérins hydrauliques. Lorsque les vérins
hydrauliques de la station de poussage 4 sont en fin de
course, la station d'ancrage 3 est libérée et rétractée
vers la station d'excavation 5, à l'aide des vérins
hydrauliques de la station de poussage 4. La place
nécessaire à l'emplacement d'un élement d'un revêtement
auxiliaire 7 est ainsi libérée à l'arrière du
microtunnelier 2. La procédure susdite est répétée, en
commençant par un nouvel ancrage du microtunnelier 2.Using the
A l'arrière du microtunnelier, le revêtement est placé en
deux étapes, c'est-à-dire une premiere étape au cours de
laquelle un premier revêtement ou revêtement auxiliaire 7,
destiné à reprendre durant la réalisation du tunnel, les
pressions du sol 1 (de l'ordre de 1 MPa), est mis en place
et une deuxième étape au cours de laquelle un deuxième revêtement ou revêtement
final 8, destiné à reprendre les pressions du sol 1 à long
terme (de l'ordre de 5 MPa), est mis en place.At the rear of the microtunnelier, the covering is placed in
two stages, i.e. a first stage during
which a first coating or
Le revêtement auxiliaire 7 est formé d'éléments de tube 9,
par exemple en métal, d'une épaisseur comprise entre 5 et
10 mm, et donc quelque peu élastiquement déformable, qui
sont sectionnés sur toute leur longueur et repliés sur eux
mêmes, tel que représenté à la figure 2. Ces éléments de
tube 9 peuvent être acheminés, les uns derrière les autres,
en position repliée, jusqu'au niveau de leur emplacement en
les poussant au travers des éléments de tube 9 déjà en
place, tel que représenté à la figure 2. Au niveau de leur
emplacement, les éléments de tube 9 s'ouvrent par leur
propre élasticité et reprennent leur position initiale,
c'est-à-dire la position qu'ils avaient après leur
sectionnement, tel que représenté à la figure 3, laissant
ainsi une ouverture longitudinale 10. Chaque élément de
tube 9 est muni sur sa face extérieure au niveau de la
section longitudinale, d'un guide 11 formé par un rebord
courbé. La fonction de ce guide fait l'objet d'un autre
paragraphe.The
La pose du revêtement auxiliaire 7 est réalisée de la
manière suivante: un premier élément de tube 9 est mis en
place dans le microtunnel; les éléments de tube 9 suivants
sont préalablement repliés sur eux-mêmes et introduits les
uns après les autres, tel que représenté en coupe à la
figure 2, à partir de la galerie principale 16, au fur et à
mesure que le microtunnelier 2 excave.The installation of the
Il est possible de maintenir les éléments de tube 9 en
position repliée au cours de leur introduction, par un
dispositif approprié, comme par exemple des lanières, ce
dispositif permettant de libérer les éléments de tube au
niveau de leur emplacement.It is possible to hold the
Les éléments de tube 9 sont ainsi poussés jusqu'au niveau
de leur emplacement, à l'aide d'une station de poussage 13,
placée dans la galerie principale 16.The
Les forces de frottement ne dépendent donc plus de la
pression du sol 1, puisque celle-ci est reprise par les
éléments de tube 9 durant le creusement du microtunnel.The friction forces therefore no longer depend on the
Afin d'empêcher l'entraínement des éléments de tube 9 en
place, lors du poussage des éléments de tube 9 repliés, les
éléments de tube 9 sont rendus solidaires par des
dispositifs de calage appropriés.In order to prevent entrainment of the
Au niveau de leur emplacement, les éléments de tube 9
s'ouvrent par élasticité, tel que représenté à la figure 3,
laissant une ouverture longitudinale 10. Le guide 11 susdit
limite le mouvement des parois de l'élément de tube 9.At their location, the
La section longitudinale de chaque élément de tube 9 est
telle qu'un bord de l'ouverture 10 soit pourvu d'une
rainure en V 14 et que l'autre bord de cette même ouverture
10 possède une extrémité correspondante 15 en V, tel que
représenté en détail à la figure 4.The longitudinal section of each
Suite à la convergence du sol 1, l'ouverture 10 se referme.
Le guide 11 et la rainure 14 jointe à l'extrémité 15 de
l'élément de tube assurent une parfaite fermeture de cet
élément de tube 9 lorsque le sol 1 argileux a convergé, tel
que représenté à la figure 5.Following the convergence of the
Lorsque le dernier élément de tube 9 replié a été introduit
dans le microtunnel, la mise en place du revêtement final 8
en métal débute. Ce revêtement final 8 étanche est destiné
à reprendre la pression exercée par le sol 1 à long terme.
Ce revêtement final 8 a un diamètre extérieur égal, aux
tolérances près, au diamètre intérieur du revêtement
auxiliaire 7 avec les éléments de tube 9 dans leur position
fermée.When the last folded
Le revêtement final 8 est introduit sous forme d'éléments
de tube 12 qui sont poussés, les uns après les autres, à
partir de la galerie principale 16, à l'aide de la station
de poussage 13. Au fur et à mesure de leur introduction,
les éléments de tube 12 sont soudés afin d'assurer leur
étanchéité.The
Le revêtement final 8 peut être utilisé pour pousser vers
leur emplacement les derniers éléments de tube 9. The
Le microtunnel est réalisé dès que tous les éléments de
tube 9 se trouvent à leur emplacement et que tous les
éléments de tube 12 du revêtement final 8 ont été
introduits.The microtunnel is carried out as soon as all the elements of
Le procédé décrit ci-dessus permet, de manière simple et continue, de réaliser des tunnels dans des sols convergents à grande profondeur.The process described above allows, in a simple and continues to build tunnels in converging soils at great depth.
Il est évident que de nombreuses modifications peuvent être apportées à l'exemple susdécrit, sans pour autant sortir du cadre de l'invention telle que décrite dans les revendications ci-après.It is obvious that many modifications can be made to the example described above, without however leaving the scope of the invention as described in claims below.
En particulier, l'excavation ne doit pas nécessairement
être un microtunnel horizontal. Elle peut être un tunnel,
une galerie ou n'importe quelle excavation horizontale ou
inclinée ou même verticale. Le microtunnelier 2 peut selon
le cas être remplacé par un autre dispositif d'excavation
approprié.In particular, excavation need not necessarily
be a horizontal microtunnel. It can be a tunnel,
a gallery or any horizontal excavation or
inclined or even vertical. The
Au lieu de prendre appui sur le sol, le tunnelier ou autre
dispositif d'excavation peut prendre appui sur
les éléments de tube 9 déjà mis en place. Ainsi la station
d'ancrage 3 peut être éliminée ou remplacée.Instead of resting on the ground, the tunnel boring machine or other
excavation device can build on
the
Dans une variante du procédé décrit, les éléments de tube 9
du premier revêtement, sont repliés dans une position stable (et ne sont donc plus maintenus en compression) et, au lieu de s'ouvrir par leur propre
élasticité, sont étendus mécaniquement à leur emplacement final,
par exemple par des vérins. In a variant of the method described, the

en métal. Ils peuvent par exemple être en matière
synthétique.These
