The invention relates to a building including a facing, a backfill at the back of the facing, synthetic reinforcement strips distributed in the backfill, and a connection system between the reinforcement strips and the backfill. The connection system includes fasteners having the shape of a continuous closed loop, each including two first portions for hooking to the facing and, alternating with the first portions along the closed loop shape, two second portions extending towards the back of the facing where they are folded back to form two loops inside of which at least one reinforcement strip extends.

Building with reinforced ground

A reinforced soil structure comprising:&#x2014;a fill ();&#x2014;a facing () placed along a front face of the structure;&#x2014;at least one main reinforcement member () connected to the facing and extending through a first reinforced zone (Z) of the fill situated behind said front face; and&#x2014;at least one secondary reinforcement member () disconnected from to the facing and extending in a second reinforced zone (Z) of the fill which has, with said first reinforced zone (Z), a common part (Z'), wherein the secondary reinforcement member () extends into the fill () up to a distance substantially shorter than the main reinforcement member (), with respect to the front face and wherein the stiffness of the secondary reinforcement member () is greater or equal to the stiffness of the main reinforcement member ().

Reinforced soil structure

A civil engineering work () comprising a front face (), a facing () having a back surface () and a front surface () that is substantially the same as said front face () of the work, a fluid-tight covering () on the back surface, a fill () arranged behind said fluid-tight covering (), and an anchoring device () ensuring a mechanical linkage between the facing () and the fill (), with said facing () comprising a cavity () inside of which a portion of the fluid-tight covering () is arranged to form a recessed space into which is inserted an anchoring element () that is a part of said anchoring device (), and a method for implementing such a work.

Continuous fluid tightness for a civil engineering work

The invention relates to a structure including a fill (), reinforcing strips (), and facing (), the reinforcement strips () being anchored to the facing (). The facing incorporates a path formed for a reinforcement strip () between two emergence points (PE, PE) that are located at the back surface () of the facing, wherein the path comprises: two adjacent portions () that are placed so as to position each strip within an emergence plane (P, P); two curved portions () provided as extensions of the two adjacent portions () and arranged so as to deviate the strip out from the emergence planes (P, P); and a connecting portion connecting together the two curved portions (). In the structure, both emergence planes (P, P) are distinct and separated by a physical separator, and the connecting portion includes at least one loop () located outside the emergence planes (P, P) and outside the space between said emergence planes. The invention also relates to a related facing element.

Reinforced ground structure, and siding elements for constructing same

Link device () between a facing element () of a reinforced ground construction work () and a longitudinal reinforcement (), intended to extend in a backfill (), which comprises a portion () for fixing to the facing element (), two connecting portions (), of which a first end of each of them is linked to a point of the fixing portion (), in which a second end of each connecting portion is linked to a first end of a first and of a second return portion (), in which the return portions () are substantially parallel to one another and in which a second end of each of the return portions is linked to a securing segment () substantially perpendicular to the return portions ().

Connection device for a reinforced earth structure and related structure and method

Reinforced stabilizing strip () intended for use in reinforced earth structures, comprising a longitudinal part (), said longitudinal part () comprising along at least part of its length, at least one cord () arranged approximately longitudinally and encased in the bulk of said longitudinal part.

Reinforced stabilising strip intended for use in reinforced earth structures

The facing element for a stabilized soil structure comprises a body of cast material inside which a path is formed for a reinforcement strip between two points of emergence situated on a rear face of the element. This path includes two rectilinear portions which are respectively adjacent to the two points of emergence and are each arranged so as to position the strip in the same plane of emergence perpendicular to the rear face, two curved portions which respectively continue the two rectilinear portions and are arranged so as to deviate the strip from the plane of emergence, and a connection portion which joins the two curved portions to one another and has at least one loop situated outside the plane of emergence.

Method and device for inserting a drainage wick

A method and device for inserting a drainage wick into the ground wherein the method includes the steps of:

The stabilized earth or reinforced soil structure comprises a fill, a facing placed along a front face of the structure, main reinforcements disconnected from the facing and extending in a reinforced zone of the fill situated behind the front face, and secondary elements connected to the facing and extending in a zone of the fill which exhibits, with the reinforced zone, a common part where loads are transmitted between the main reinforcements and the secondary elements by the material of the fill.

Stabilized earth structure and method for constructing it

At least one cable is attached to a load lying on the ground via a releasable connection mechanism. A traction force is applied to the cable to hoist the load up to a prescribed height. That traction force is then eliminated or reduced to initiate a downward movement of the load followed by the cable. The connection mechanism is then released while the load is moving downwardly.
