Dimecres 12 de gener l’alumnat de 6\u00e9 B de prim\u00e0ria de l\u2019Escola Miquel Mart\u00ed i Pol<\/strong> de Sant Feliu de Llobregat ha investigat les roques que es troben a les Escletxes del Papiol<\/a>.<\/span><\/p>\n

\"\"S’han posat el casc de ge\u00f2leg i han comentat\u00a0 diversos aspectes del relleu de la zona i dels fen\u00f2mens naturals relacionats amb el terreny. Han demostrat ser uns bons coneixedors del tema.<\/span><\/p>\n

Despr\u00e9s de revisar el material necessari per investigar, s’han posat mans a la feina. Primer han observat que les Escletxes es troben en un vessant i han diferenciat dos tipus de materials: un de superior blanquin\u00f3s i un d\u2019inferior vermell\u00f3s.<\/span><\/p>\n

Per descobrir de quins materials es tractava han fet un seguit de proves en ambdues roques, com comprovar la consist\u00e8ncia, la permeabilitat o veure si reaccionava amb l\u2019\u00e0cid clorh\u00eddric. Han confirmat que el material superior s\u00f3n roques calc\u00e0ries i l\u2019inferior s\u00f3n argiles. <\/span><\/p>\n

A continuaci\u00f3 s\u2019han endinsat en 4 escletxes i han mesurat la direcci\u00f3, l\u2019amplada i la profunditat de cadascuna.<\/span><\/p>\n

\"\"Per concloure han fet una posada en com\u00fa i han dedu\u00eft com s\u2019havien format. Com qu\u00e8 les roques calc\u00e0ries es van degradant a causa de la lleugera acidesa que cont\u00e9 la pluja, durant milions d\u2019anys les esquerdes de les roques s\u2019han anat fent m\u00e9s i m\u00e9s grans fins arribar a permetre a l’aigua arribar a les argiles inferiors. Aquestes esquerdes cada vegada s\u00f3n m\u00e9s amples perqu\u00e8 les argiles fan que les roques calc\u00e0ries llisquin vessant avall.<\/span><\/p>\n

Finalment han conegut la problem\u00e0tica de les cases del Papiol, que tamb\u00e9 es troben afectades per esquerdes a les fa\u00e7anes i han fet d\u2019arquitectes proposant diverses solucions per evitar l\u2019aparici\u00f3 d\u2019aquestes.<\/span><\/p>\n

Enhorabona per la gran feina realitzada! Fins a la propera.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
