Abstract

Improvement to the method according to the main patent characterised in that the hollow abutments A, while remaining monolithic, are divided into a plurality of levels 1, each level having a height which is determined as a function of the nature of the ground to be penetrated. The levels 1 of the abutments have inclined forepeaks 2 equal in number to that of the levels. The tips 3 of these forepeaks are located in the same vertical plane 4. Each level is separated by an intermediate slab forming bracing. The weight 11 from the upper forepeak 10 determines an excess load preventing the half-abutment A from moving up at the start of the driving operation.

Description

le présent certificat d'addition concerne un perfectionnement au procédé selon le brevet principal nO 86-06694 du 9 mai 1986. this certificate of addition relates to an improvement to the process according to main patent no. 86-06694 of May 9, 1986.

Le fonçage des culées de grande hauteur peut présenter deux risques importants d'éboulements.The sinking of very large abutments can present two significant risks of landslides.

. Lors du fonçage la cohésion du terrain a une incidence
directe de ce point de vue.. When driving the cohesion of the ground has an impact
direct from this point of view.

. En outre, après accostage des demi-culées lors du terras
sement des merlons centraux, la difficulté et les dangers
augmentent proportionnellement à la longueur à blinder.. In addition, after docking the half-abutments during the terras
the central merlons, the difficulty and the dangers
increase in proportion to the length to be shielded.

Selon la présente invention, les culées creuses, tout en restant monolithes sont àsvisees en un ou plusieurs étages, chaque étage présentant une hauteur déterminée en fonction de la nature du terrain à traverser.According to the present invention, the hollow abutments, while remaining monoliths, are screwed into one or more stages, each stage having a height determined according to the nature of the terrain to be crossed.

Selon une caractéristique particulière, les étages des culées présentent des avant-becs inclinés en nombre égal à celui des étages des culées creuses. Ainsi la pointe de chaque avant-bec se situe sur un même plan vertical.According to a particular characteristic, the stages of the abutments have inclined fore-nozzles in a number equal to that of the stages of the hollow abutments. Thus the tip of each forebeak is on the same vertical plane.

Les caractéristiques de la présente addition seront plus explicitement encore précisées à travers la description qui suit dtun exemple de réalisation donné à titre indicatif et non limitatif, en référence au dossier annexé sur lequel: . La figure 1 est une vue en coupe transversale d'une
demi-culée à deux étages selon l'invention.The characteristics of this addition will be more explicitly specified in the following description of an exemplary embodiment given by way of non-limiting example, with reference to the attached file in which:. Figure 1 is a cross-sectional view of a
two-stage half-abutment according to the invention.

. La figure 2 précise, avec la demi-culée selon la figure 1.  . Figure 2 specifies, with the half-abutment according to Figure 1.

le gain réalisé sur la distance de porte à faux d'une
culée de même hauteur non étagée.the gain achieved over the cantilever distance of one
abutment of the same height, not stepped.

. La figure 3 illustre, vu de côté, l'accostage ae deux
demi-culées selon la figure 1.. Figure 3 illustrates, seen from the side, docking with two
half-abutments according to Figure 1.

. La figure 4 illustre un perfectionnement complémentaire
apporté à la demi-culée selon l'invention.. Figure 4 illustrates a further development
brought to the half-abutment according to the invention.

Sur la figure 1 la référence (1) désigne les deux étages d'une demi-culée A qui présentent chacun un avant-bec (2) incliné avec une trousse coupante ou pointe (3) se situant dans un même plan (41. In FIG. 1, the reference (1) designates the two stages of a half-abutment A which each have a front spout (2) inclined with a cutting bag or point (3) lying in the same plane (41.

L'inclinaison moyenne des avant-becs (2) étant dans l'exemple donné de 450 (1/13, on peut donc conserver une pente (5) à 3/2 lors du terrassement du front de taille en cours de fonçage (voir figure 2). Le résultat est ainsi une diminution (6), ou gain, représentatif de la longueur théoriquement nécessaire en cas d'avant-bec à pente unique pour assurer la stabilité du talus.The average inclination of the fore-beaks (2) being in the example given 450 (1/13, it is therefore possible to keep a slope (5) to 3/2 during the earthworks of the cutting face during sinking (see The result is thus a reduction (6), or gain, representative of the length theoretically necessary in the case of a single-slope forearm to ensure the stability of the slope.

L'accostage des deux demi-culées A étant réalisé (voir figure 3), il est nécessaire de blinder les piedroits latéraux de celles-ci au fur et à mesure du terrassement des merlons centraux (7). Ce terrassement et ce blindage sont exécutés de haut en bas. Le fractionnement des avantbecs (2) permet de réduire la longueur et la surface de blindage.The docking of the two half-abutments A having been carried out (see FIG. 3), it is necessary to shield the lateral legs thereof as and when the central merlons (7) are earthed. This earthworks and this shielding are carried out from top to bottom. The splitting of the fronts (2) makes it possible to reduce the length and the area of shielding.

En plus des deux cas précités (sécurité au fonçage et au blindage après accostage) les culées étagées A apportent deux avantages supplémentaires.In addition to the two aforementioned cases (driving safety and shielding after docking) the stepped abutments A provide two additional advantages.

. La ou les dalles intermédiaires (8) servent Be buton
en phase définitive ; elles permettent donc de diminuer
la quantité d'acier dans les piedroits.. The intermediate slab (s) (8) serve as Be buton
in the final phase; they therefore reduce
the amount of steel in the legs.

. De plus les avant-becs étant eux aussi fractionnés en
"dents de scie" (voir figure 4) au début du fonçage
il n'y a que la adent" ou bec inférieur (9) qui pénètre
dans le talus. La charge du remblai (B) sur cet avant-bec
est donc relativement faible, ce qui entraine un risque
de soulèvement (ceci est aussi vrai avec un avant-bec
à une seule partie). L'avant-bec supérieur (10) apporte
donc une surcharge permanente schématisée par la
fleche (11) qui évite ainsi tout risque de soulèvement
des culées (1). . In addition, the fore-beaks also being divided into
"sawtooth" (see figure 4) at the start of driving
there is only the adent "or lower beak (9) which penetrates
in the embankment. The fill load (B) on this forebeak
is therefore relatively low, which entails a risk
lifting (this is also true with a forearm
to a single party). The upper front spout (10) provides
therefore a permanent overload schematized by the
arrow (11) which thus avoids any risk of lifting
abutments (1).
