Le chantier de creusement de la nouvelle ligne de métro n°15

Le chantier de creusement de la nouvelle ligne de métro n°15 a débuté debut février 2020, pour la portion entre pont de Sèvres et la station Clamart (Fort d’Issy). Les déblais seront évacués par des barges, qui viennent charger au bout de notre ponton. 

Quelques règles de fonctionnement sont modifiées :

Il nous est interdit de franchir la ligne de bouées jaunes situées en amont du ponton, pour éviter les remous de l’hélice de la barge en cours de chargement. C’est la barge qui se déplace en plusieurs passes, pour se faire charger sous le tapis du convoyeur.

Cette barge va limiter notre visibilité vers l’amont du ponton et nous masquera en partie la vue des bateaux qui descendent la Seine (bateaux avalant).

Des feux de signalisation vert et rouge ont été installés. Le feu rouge sera déclenché, soit par une caméra détectant un bateau descendant la Seine en amont du quai de chargement, soit lors des manœuvres d’appontage et de départ des barges de chargement. S’il s’agit d’un ou plusieurs bateaux descendant la Seine, il sera interdit de partir du ponton (temps assez court). S’il s’agit d’une manœuvre de barges, il sera interdit de partir du ponton et d’apponter. Le délai indicatif de ces manœuvres qui nous a été communiqué est d’une demi-heure. Lorsque le feu sera vert, nous pourrons partir et arriver au ponton librement.

Les clubs vont se voir dotés de radios VHF, qui permettront de communiquer avec la personne responsable du chargement des barges. En outre, un tableau d’affichage devrait être mis en place, qui renseignera de façon indicative sur les horaires des prochaines manœuvres des barges. Il nous a été indiqué qu’il y aurait environ une manœuvre par jour, tous les jours sauf le dimanche à partir du mois de mai, pour environ 18 mois. D’ici là, la montée en régime devrait être très progressive.

    Insert a Flickr photo. A working example:
    • [flickr-photo:id=7357144724, size=m, mintitle=999, minmetadata=999] (accepts only the parameters id, class, style, size, mintitle and minmetadata)
    To float single photos use [flickr-photo:id=9247386562, class="floatright"], [flickr-photo:id=9247388074, style="float:left;"] or use the AutoFloat module (recommended).

    Insert a Flickr album. Working examples:
    • [flickr-photoset:id=72157634563269642, size=s, num=8, tags=kids/men, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]
    • [flickr-gallery:id=72157648989290536, size=q, num=4, sort=views]
    • [flickr-group:id=91484156@N00, size=q, num=8, tags=flowers, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]
    • [flickr-user:id=lolandese1, size=q, num=6, tags=kids/men, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]
    • [flickr-user:id=public, size=q, num=10,tags=Augusto Canario, filter=interesting, sort=views, extend=true]
    • [flickr-user:id=public, size=q, num=8,location=48.867556/2.364088, date=2015-01-11, filter=interesting, sort=views]
    • [flickr-favorites:id=lolandese, size=q, num=4, tags=tomosborn/people, media=all, sort=random, count=false, mintitle=999, minmetadata=999, heading=none]

    Common sizes:
    s : small square 75
    t : thumbnail, 100 on longest side
    q : big square 150
    m : small, 240 on longest side
    n : small, 320 on longest side
    - : medium, 500 on longest side
    x: Responsive slideshow (for group, set and user IDs only)
    y: Basic responsive slideshow (for set and user IDs only)
    The 'c' size (800px) is missing on Flickr images uploaded before March 1, 2012. Photos with non existing sizes will be skipped in albums.

    TIP: Not only the node body but also blocks make use of a text format. Build your own custom Flickr album block using the Flickr Filter syntax.

    PARAMETER EXAMPLES. Omitting a parameter will result in the default value to be used.
    id=lolandese1 : A photo, set, user or group ID. id=public grabs CC licensed public photos (only for [flickr-user:...]). Default: id=[undefined] (set in config).
      Find a Flickr group ID. Valid ID values: numeric ID (the one that contains a '@'), path alias, Flickr username or the user's email.
    class="floatleft foo bar" : Syntax as in HTML. Wrap the value in quotes (or not) and put spaces between multiple classes.
      Applies to the outer HTML element of a photo or album.
    style="float:left; border:solid 2px;" : Syntax as in HTML. Wrap the value in quotes (or not) and put semicolons between different style declarations.
      Applies to the outer HTML element of a photo or album.
    size=q : Big square (150px). The sizes x and y display a slideshow and ignore number, media, tags, location and sort settings.
      Default single photo: size=m, album photo: size=s (both set in config).
    num=4 : Display 4 photos. Default: num=6 (set in config). For albums only.
      If set to 1, the single image will behave as such. Heading and counter will be omitted, and float might apply.
      Used to display a single changing random or recent image.
    media=all : Display both photos and videos. Default: media=photos. For albums only.
    tags=kids/men : Separate multiple tags with a slash (/). Display all set, group or user photos that contain the indicated tags.
      Case insensitive, matches any tag, for photosets and galleries even partial. You can exclude results that match a term by prepending it with a - character.
      Public albums will only display photos that match all tags. Like on Flickr spaces are removed from tags (e.g. 'Victoria park' becomes 'victoriapark').
      For albums only.
    extend=true : Extend the tag filter to search for matching terms also in the Flickr photo title and description besides Flickr tags.
      Default: extend=true (set in config). For albums only.
    tag_mode=all : Matches 'all' defined tags (AND). The other possible value is 'any' (OR).
      If this parameter is omitted, 'all' is used if no Flickr user ID is known (public search), otherwise 'any' is used. For albums only.
    location=48.85837/2.294481/0.2 : Display photos within 200 mt from the Eiffel Tower. Lat/lon/radius (in km). Separate values with a slash (/).
      To get the coordinates for a location, right-click on a Google map and choose 'What's here?' or copy/paste it from the URL.
      Substitute the comma (,) with a slash (/). Optionally add a radius to force a major number of results to filter on (max. 32 km).
      If the radius is omitted it defaults to 14 meter and gradually expands to 32 km until a sufficient number of results are returned.
      Besides decimal coordinates also degrees are accepted, e.g. 2° 21' 50.72". For user and group albums only, also public.
    date=2015-01-11 : Display photos taken on 11 January 2015.
      Many accepted date formats (e.g. '11 Jan 2015'), also relative formats (e.g. 'first day of last month | last day of last month').
      Separate two date values with a vertical bar (|) to cover a timespan of multiple days. For user and group albums only, also public.
      Tip: Use a date in combination with a location to grab public photos of an event.
    heading=h3 : Wraps the album title in HTML tags. Use 'p' to apply no style or 'none' to suppress the title. Default heading=p (set in config). For albums only.
    sort=views : Display the most viewed Flickr photos first (popularity, slower response after cache clear).
      Other values: unsorted = recent as delivered by the Flickr API (fastest response),
      random (slower response after cache clear), taken (newest first), posted (newest first) , added (for groups only, newest first) and id (on photo ID, newest first).
      Default: sort=unsorted. For albums only.
    filter=interesting : Display the most interesting photos. Other possible value: relevant. For user and group albums only, also public.
    count=false : Suppress display of the counter under the album (e.g. 5 out of 124 on Flickr). Default: count=true (set in config). For albums only.
    mintitle=999 : Suppress display of the title in the photo captions for images below a width of 999 px. Default: mintitle=100 (set in config).
    minmetadata=999 : Suppress display of the metadata in the photo captions for images below a width of 999 px. Default: minmetadata=150 (set in config).
