Process for the treatment of the tree trunks cut, by impregnation of the fibers of a solution of treatment and for the installation of the tree trunks cut traimtement

摘要

The present invention relates to a process for the treatment of the tree trunks cut, by impregnation of the fibers of a solution of treatment (1) adapted, in which the said solution is injected under pressure, longitudinally to the trunk (tr), from a (41) of its front ends (41, 42). According to the invention: - is injected into the treatment solution (1) in the direction of the flow of sap, - of the effluents are recovered (2), such as the sap, expressed by the trunk (tr) during the injection of the treatment solution, and - is recycled said effluents by the addition of at least a treatment product (3, 31) in order to obtain a solution of treatment for the treatment of impregnation of a frustum of a new injection phase.
