Abstract
A reinforcement element for a diaphragm wall including a reinforcement cage, the reinforcement element further including a seal-carrier provided with a mounting part for receiving at least one seal, which is elongated, the seal-carrier being fixed to the first end part of the reinforcement cage and extending along the longitudinal direction of said reinforcement cage, the seal-carrier defining a housing for receiving the seal, at least a first part of which is surrounded by a sacrificial material.

A reinforcement element for a diaphragm wall including a reinforcement cage which has a height defining a longitudinal direction, a width and a thickness, the reinforcement cage having a first end part and a second end part considered along the width as opposite to the first end part, the first and second end parts extending along the longitudinal direction of the reinforcement cage, the reinforcement element further including at least one seal-carrier provided with a mounting part for receiving at least one seal which is elongated, the seal-carrier being fixed to the first end part of the reinforcement cage and extending along the longitudinal direction of said reinforcement cage, the seal-carrier having two flanges extending along the longitudinal direction and a bottom so as to define a housing for receiving the seal, at least a first part of which is surrounded by a sacrificial material.
A method for making a diaphragm wall in the ground, comprising:
- drilling a first vertical trench in the ground;
- placing in the first trench a reinforcement element for a diaphragm wall including a reinforcement cage which has a height defining a longitudinal direction, a width and a thickness, the reinforcement cage having a first end part and a second end part considered along the width as opposite to the first end part, the first and second end parts extending along the longitudinal direction of the reinforcement cage, the reinforcement element further including at least one seal-carrier provided with a mounting part for receiving at least one seal which is elongated, the seal-carrier being fixed to the first end part of the reinforcement cage and extending along the longitudinal direction of said reinforcement cage, the seal-carrier having two flanges extending along the longitudinal direction and a bottom so as to define a housing for receiving the seal, at least a first part of which is surrounded by a sacrificial material;
- pouring concrete into the first trench then, after hardening of the concrete, drilling a second vertical trench in the ground, juxtaposed with the first vertical trench on the side of the seal-carrier;
- discharging the sacrificial material out of the housing using a scraping tool including two parallel teeth spaced apart from each other so as to define a passage for the seal, the width of the scraping tool being substantially equal to the distance between the flanges of the seal-carrier, so that the first part of the seal extends into the second trench;
- and
- putting concrete in the second trench.
