AmaHidromill Kits

Ama-hydromill kit amephumela imishini ekhethekile eyakhiwe ukuze iqhutshwe kahle ukusebenza kwe-mechanical cutting nokuzinzisa inhlabathi nezinto ezintathu ezintsha ezindaweni ezijulile zokwakha. Lezi zinhlelo zibalulekile ekwakheni odongeni be-diaphragm, ama-curtain okuvinjwa, nezinsimbi ezikhandekayo noma eziheldayo ezidinga ukuthonya izimo zomhlaba ezinzima ezijulile kwesinye isikhathi ezingaphezu kwamamitha angama-50. Ngokuhlanganisa umsebenzi wokusika ngemishini nokuphuma kwegazi okuqhubekayo, ama-hydromill kit avumela ukuhamba okuyiqiniso okujule kakhulu lapho i-trenching engasekeli izodala ukuwa kodonga, ukulahlekelwa okukhulu kwe-slurry, noma ukuhamba okungamukelekile kumasimu wokwakha. Umqondo wokusebenza kwe-hydromill kit ugxile ekhanda lesi sikhumbuzo elijikekayo nelishumekiwe elinamasu asuswayo—ama-drags, ama-disk cutters, noma ama-wheels cutters—okhula kancane kancane uhamba kumugqa owaziwa. Njengoba udoti ususwa, i-slurry ye-mineral (ivamile i-bentonite noma ama-suspension esekelwe ku-polymer) igcina ukuqina kodonga ngokwakha i-filter cake ezindaweni ezivele ziboniswe ngenkathi ibamba izinto ezitholiwe ukuze zibuye zisetshenziswe. Le ndlela esekelwa yi-slurry ihlukanisa izinhlelo ze-hydromill ezivela kuma-cutter we-mechanical diaphragm wall futhi ibalulekile ezindaweni ze-granular soils, izakhiwo ezithola amanzi, nemigodi ye-rock ebuqamamanga lapho ukuzinza kwemishini kuphela kunganele. Ama-hydromill kit asetshenziswa ezindaweni eziningi ezahlukahlukene zokwakha ezijulile: odongeni be-diaphragm abPermanent nabTemporary, ama-curtain okuvinjwa kwemvelo noma okuhamba ngamanzi, izinhlelo ze-secant pile wall, odongeni okulungiswa kwe-soil-cement, nokulungiswa kwezakhiwo. Ukuhlela kwezimoto phakathi kweziqondiso kudinga amajometri ahlukahlukene akhanda okusika, izindawo zokujiya ezilungisekayo (ivamile 8–30 rpm), imibandela yokushumeka (0.5–2.0 metres), kanye ne-slurry eyenziwe ngokwezifiso ilungele ukuhlangana nezimo ze-lithology ne-hydrogeological. Ingxenye ye-hydromill kit ibandakanya iyunithi yekhanda lokusika enevidiyo ezingu-ukuhlukahluka ezenzekelayo, izinhlelo zokuhola eziphakeme (ama-rails guided noma izinhlelo ze-kelly bar ukuze zihlale ziqondiswayo), kanye nezinsizakalo zokuphathwa kwe-slurry. Lokhu kuhlanganisa izitsha zokuhlanganisa, amapompo okuphuma, izinto zokuhlukanisa nezokuhlukanisa (ama-screen avibrating, ama-hydrocyclones, noma ama-centrifuges), nemijikelezo yokubuyisela ikhwalithi ye-slurry ukuze kuhambisane kokusebenza. Ububanzi bekhanda lokusika bunjengama-0.8 kuya kumama-1.5 metres yamapaneli ajwayelekile, bukhanyisa ku-1.8 kuya ku-2.0 metres uma kudingeka izindonga ezinzima noma ezibanzi. Ama-kits amanje avame ukufinyelela imiyakha esisekelweni engu-100+ meters, okudlulisela kuphela nge-pressure capacity ye-slurry kanye nezakhiwo eziqinile zezisekelo. Ukukhetha i-hydromill kit efanele kudinga ukuhlola izinto eziningi ezixhumene: ubukhulu bokuhlatshwa obulindelekile (obuchaphazela ubukhulu be-slurry nokuphathwa kwengcindezi), ukuhlukaniswa kwendawo nezinhlaka (ubukhulu obunqunywe, ukusabalala kwamaseli, ukuhamba), ukuvuma okudingekayo kodonga (ukuphambuka okujwayelekile ±75–150 mm ngaphansi kobukhulu be-panel), kanye nendawo ye-logistics ethile. Idatha yokuhlola umhlaba evela ezibhozweni ezedlule kanye nezivivinyo ze-geotechnical laboratory iphrothwe lezi zinqumo, iqinisekisa ukuthi ukucaciswa kwe-kit kuhambisana nezimo zangaphakathi zangempela nezidingo zokwakha. Imeyili yezimboni ibhalwe ku-EN 1538 (Ukuphothulwa kwemisebenzi ekhethekile ye-geotechnical—Odongeni be-diaphragm), eyichaza izindinganiso zekhwalithi ezihlanganisa ukumiswa komugqa wokubhukuda kodongwe nobukhulu beodonga. Izindinganiso ze-ISO 22475 zikhuluma ngama-methologies wokuhlola isiteshi ngaphambi kokufakwa kwe-hydromill. I-DIN 4126 ihlinzeka ngemicabango ethula ngemigudu ye-German yokuphothulwa kodonga lwe-slurry kanye nezindlela zokuhlola ikhwalithi.
