Avant de percer des orifices dans le tube CMT, faites un croquis de la conception souhait\u00e9e du puits. Indiquez les profondeurs des zones de surveillance et des centralisateurs (le cas \u00e9ch\u00e9ant) en pieds ou en m\u00e8tres sous la surface du sol. Indiquez \u00e9galement les profondeurs des lev\u00e9es de sable et de bentonite souhait\u00e9es, comme le montre le graphique de la figure 1. <\/span><\/p>\n[\/et_pb_text][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=\u00a0\u00bb4.27.4″ _module_preset=\u00a0\u00bb3676f7e6-7b83-4698-94ce-2cc9fa9ae43d\u00a0\u00bb hover_enabled=\u00a0\u00bb0″ global_colors_info=\u00a0\u00bb{}\u00a0\u00bb sticky_enabled=\u00a0\u00bb0″][et_pb_column_inner saved_specialty_column_type=\u00a0\u00bb3_4″ _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb][et_pb_image src=\u00a0\u00bbhttps:\/\/www.solinst.com\/wp-content\/uploads\/2024\/11\/fig1-3-channel-403-cmt-schematic.webp\u00a0\u00bb alt=\u00a0\u00bbfigure 1 syst\u00e8me cmt multiniveau \u00e0 3 canaux sch\u00e9ma de l'installation du port d'\u00e9chantillonnage\u00a0\u00bb title_text=\u00a0\u00bbFigure 1 – Sch\u00e9ma du syst\u00e8me CMT multiniveau \u00e0 3 canaux de la configuration du port d'\u00e9chantillonnage\u00a0\u00bb align=\u00a0\u00bbcenter\u00a0\u00bb _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb width=\u00a0\u00bb50%\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb][\/et_pb_image][et_pb_text _builder_version=\u00a0\u00bb4.27.2″ _module_preset=\u00a0\u00bbdefault\u00a0\u00bb global_colors_info=\u00a0\u00bb{}\u00a0\u00bb]<\/p>\n

Cela sera utile lorsque vous mesurerez la profondeur des mat\u00e9riaux de remblai pendant la construction du forage. Si vous construisez un puits CMT dans lequel des couches altern\u00e9es de sable et de bentonite sont ajout\u00e9es \u00e0 partir de la surface, essayez de pr\u00e9voir au moins deux pieds de sable au-dessus et au-dessous des orifices de surveillance pour vous assurer que la bentonite ne recouvre pas les orifices de surveillance.

Utilisez un couvercle de puits de grande taille (un diam\u00e8tre sup\u00e9rieur \u00e0 4″ est recommand\u00e9) afin de laisser suffisamment d’espace pour acc\u00e9der \u00e0 la t\u00eate de puits.
