Abstract
A method for manufacturing an element in a ground comprising a drilling step during which a grout comprising a first composition is introduced and after the drilling step, at least one grout activation cycle is performed during which at least part of the grout is pumped; a second composition configured to activate the grout by reacting with the first composition in order to initiate the hardening of said grout is added to the pumped grout; then the activated grout is introduced into the excavation; and after said at least one grout activation cycle, the activated grout is allowed to harden in order to form the element in the ground.
Claims25
A method for manufacturing an element in the ground, the method comprising:
- a drilling step during which an excavation is drilled into the ground using a drilling tool, while introducing into said excavation a grout comprising a first composition;
- after the drilling step, at least one grout activation cycle is performed during which:
- at least part of the grout is pumped;
- a second composition is added to the pumped grout configured to activate the grout by reacting with the first composition in order to initiate the hardening of said grout;
- then
- the activated grout is introduced into the excavation;
- and
- after said at least one grout activation cycle, the activated grout contained in the excavation is allowed to harden in order to form the element in the ground.
An installation for manufacturing an element in the ground, the installation comprising:
- a drilling tool configured to drill an excavation in the ground;
- an introduction device configured to introduce into the excavation, during drilling, a grout comprising a first composition;
- and
- a grout activation device comprising:
- a pumping means configured to pump the grout, after drilling;
- a means for treating the grout configured to add into the pumped grout a second composition configured to activate the grout by reacting with the first composition in order to initiate the hardening of said grout;
- and
- a means of introducing activated grout into the excavation.
