Seguidament s\u2019han dividit\u00a0en 6 grups de treball, s\u2019han posat el casc i han agafat tot el material necessari per a la seva investigaci\u00f3: martell de ge\u00f2leg, cinta m\u00e8trica, br\u00faixola i \u00e0cid clorh\u00eddric dilu\u00eft. Amb tot preparat, han fet tot un seguit de proves en ambdues roques, com comprovar la seva consist\u00e8ncia, la resist\u00e8ncia, la permeabilitat o veure si reaccionaven amb \u00e0cid clorh\u00eddric. Han confirmat que el material superior eren roques calc\u00e0ries i l\u2019inferior argiles.<\/p>\n<p style=\"font-weight: 400; text-align: justify;\">A continuaci\u00f3 s\u2019han endinsat en 4 de les escletxes i han mesurat la direcci\u00f3, l\u2019amplada i la profunditat de cadascuna. Han travessat algunes escletxes realment estretes com si fossin aut\u00e8ntics espele\u00f2legs. Ha sigut una experi\u00e8ncia emocionant!<\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-20982 alignleft\" src=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2024\/10\/2-1-291x300.jpg\" alt=\"\" width=\"302\" height=\"311\" srcset=\"https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2024\/10\/2-1-291x300.jpg 291w, https:\/\/serveiseducatius.xtec.cat\/cda-cansantoi\/wp-content\/uploads\/usu1385\/2024\/10\/2-1.jpg 485w\" sizes=\"auto, (max-width: 302px) 100vw, 302px\" \/>Amb totes les dades que han recollit, han fet una posada en com\u00fa i han dedu\u00eft com s\u2019havien format les escletxes. Com 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 que l\u2019aigua ha pogut arribar a les argiles inferiors. Aquestes esquerdes cada vegada s\u00f3n m\u00e9s amples perqu\u00e8 les argiles pastoses fan que les roques calc\u00e0ries llisquin vessant avall.<\/p>\n<p style=\"font-weight: 400; text-align: justify;\">Finalment han jugat al de les sis difer\u00e8ncies per con\u00e8ixer la problem\u00e0tica de les cases del Papiol, que sovint tamb\u00e9 es troben afectades per esquerdes a les fa\u00e7anes, i han descobert diverses solucions per evitar l\u2019aparici\u00f3 d\u2019aquestes. Han arribat a la conclusi\u00f3 que no qualsevol terreny \u00e9s apte per construir-hi o, si m\u00e9s no, caldr\u00e0 adaptar el tipus de construcci\u00f3 segons la zona.<\/p>\n<p style=\"font-weight: 400; text-align: justify;\">Han estat uns investigadors molt intr\u00e8pids i han treballat de valent!
