Izikrini zokuphakamisa

Izimpawu zezinsiza zokuphakamisa phakathi kwemcontext yeMikhawulo Yomhlaba kanye Nama-Cutoff Curtains ziwumsebenzi okhethekile ophakanyiswa ukuze ubhekane nezidingo ezinzima zokuphathwa kwezinto ezihambisana nokwakhiwa kwezakhiwo ezijulile phansi komhlaba, okubandakanya imikhawulo ye-diaphragm, ama-cutoff curtains, ama-secant piles, amasistimu e-sheet pile, kanye nezinhlelo zokugrouth ze-jet ezingezansi. Lezi zinsiza zisebenza njengemishini ebalulekile esekela ukuphepha, ukuphathwa kwesikhumbuzo sezakhiwo ezinkulu, amaqoqo owokwenziwa, ama-tremie pipes, kanye nezinsiza zewarrior ngesikhathi sokuqala okukhulu sokusebenza kwezakhiwo ezijulile, lapho ukunemba nokuzinza komthwalo kubalulekile ekugcineni ubumsulwa bezakhiwo nokuhlangabezana nemithetho. Ekubhaliseni kwemikhawulo ye-diaphragm, izinsiza zokuphakamisa zihlukanisa futhi ziphakamise izinto ze-wall guide ezifanele ngaphambi kokuba kokuqhuba kwemigudu egcwele i-slurry kuqale. Ngesikhathi sokwakhiwa, ziphakamisa ama-tremie pipes asetshenziselwa ukufakwa kwekhohlo, ziqhubele phansi amaqoqo owokwenziwa emigudwini esekelwe ku-slurry, futhi ziphathe ukuhlinzeka okwenziwayo kwezamabhola e-diaphragm esigabeni esithile. Ekufakeni ama-cutoff curtains—kungaba i-soil-cement-bentonite (SCB), i-cement-bentonite (CB), noma izinhlelo ze-vibro-replacement—izinsiza zokuphakamisa ziphathe ukufakwa kwamathubhu wokufinyelela, izinhlelo zokuhola, kanye nezinsiza zokusebenza. Ku-sistimu ye-secant kanye ne-tangent piles, izinsiza zokuphakamisa zibeka kokubili izintambo zokuphakanyiswa ezihlala njalo kanye nezakhiwo ze-guide eziphakathi. Ezinhlelweni zokugrouth ze-jet kanye nezokuhlanganiswa komhlaba, izinsiza zokuphakamisa ziphakamisa izinsiza ezinzima zokwelapha, amapayipi okuhlinzeka ngezithako, kanye nezinhlelo zokufaka ezisizayo ngesikhathi zigcina izindawo ezicacile phezu kwemigudu esebenzayo. Umqondo osebenzayo uphatheke ekuphathweni kokuphepha kwemithwalo: izinsiza zikhprovidesukuphakanyiswa okuqondile nokuphakanyiswa kokuhamba kokuphathwa komthwalo ophakeme ngaleso sikhathi, zigwema ukuphimisa okungavumelekile, ukulanda okukhulu, noma ukungena kokuphuma okungabangela ukonakala kwemikhawulo yokuhola, kuphazamisa izimpawu ze-slurry, noma ukungafani kwezinsiza zokusebenza. Umthwalo wezintambo udinga ukuba uhambisane neziteshi ezivunyelwe ezimiphishini eziphakanyisiwe, ngokubambisana nezici ze-dynamic zokuqala zembhidi zempahla kanye nemiphumela yokuhamba. Izinsiza zokuphakamisa kule mcontext ngokuvamile ziqukethe ama-crane amaphakathi e-lattice boom (20–100 t amandla), ama-crane asezindaweni zokusebenza (mandla alungile ye-segment), noma ama-crane angaphansi kwamanzi okwakhiwa kwemigudu. Izinhlelo zifaka ukuphakanyiswa kwezigaba (ama-tremie pipes, izikhala zohola), ama-hiphophopha amaphuzu afakwa phakathi kwemithwalo (ama-cages amakhulu), namablokhi ethosiwe anama-cell wokuqapha amaload ngesikhathi sangempela. Izinhlelo ezithuthukisiwe zifaka i-radar yokulwa nokungqubuzana, ama-indiketa we-load moment (LMI), kanye nezinyathelo ezihambayo ze-boom zokuqhuba ezindaweni eziqhume ezingeni lemingcele. Izicelo zokukhetha zifaka amandla aphakanyisiwe adingekayo esikhathini sikhulu, ukuzinza kwemikhumbi ngaphansi komthwalo onomthelela, ukufinyelela okuqondile ezindaweni ezinokuphikiswa, imikhawulo yokuphakamisa, izidingo zokubopha, kanye nokuqinisekiswa ngaphansi kokuhambisana ne-EN 12951 (Izidingo zokuphepha zama-crane aphakanyisiwe), EN 13000 (Ama-crane aphakanyisiwe—Ukwethembeka), kanye ne-ISO 4305 (Ama-crane—ukuhlukaniswa). Abasebenzi kufanele babe neziqu ezamukelekayo ze-crane ephakanyisiwe (IPAF, CCNR, noma okulingene) futhi baveze amakhono ezisebenzi ezikhethekile zokuphakanyiswa ngaphansi kwezinhlelo zokuphatha ezivunyelwe.
