Amathube asetshenzisiwe

Amaphampu asetshenzisiwe reprezenti izinhlelo zokufaka amakhono ezinsizakusebenza ezivuselelekayo nezitholakele ezivela kumaphrojekthi aqediwe, okwandisiwe, kanye ne-geotechnical. Lezi ngokuvamile zingamaphampu eshiselwe noma owalwa ensimbi ahlola ukuhlinzeka ngempumelelo kwezinhlelo ukuze zihlangabezane nezindinganiso zokuphindisela ezivela kumaphrojekthi okuhamba ngethuba lokwakha, ukushaya izinduku, ukufakwa kwe-micropile, nezinyathelo zokwenza ngcono umhlaba. Zenziwe ngokuyinhloko ngezinsimbi ezinamandla aphezulu (ngokuqhelekileyo ASTM A252, EN 10219, noma kumazinga afanayo), amaphampu asetshenzisiwe anikeza izixazululo ezisekeleni kumathuba wokuphatha izindleko zomsebenzi ngenkathi kugcinwa izici zokubhaka okuphezulu nokumelana nokugqwala okubalulekile ezimweni ezinzima zomhlaba. Kumaphrojekthi e-deep foundation, amaphampu avuselelekayo asebenza njengokufakwa kwesikhathi es temporary noma okungapheli kwe-rotary boring, percussion drilling, kanye ne-operations ye-auger. Ahlinzeka ngokuqinisa udonga lwe-borehole kumhlaba ome, ongazinzile, noma onegena amanzi, evimbela ukuhumeza nokulahleka kwe-slurry ngenkathi kunikezwa ukubekwa kwe-pile ok precis kanye nokwelashwa komhlaba. Amaphampu asetshenzisiwe abaluleke kakhulu ekuqedeni kwe-micropile, lapho asebenza njengokufakwa kwezokwakha ku-sistimu ye-hollow-bar kanye nezifakwa ezibhalwe phansi. Kumaphrojekthi e-diaphragm wall, amaphampu avuselelekayo asebenzisa ukuhamba koshintsho lwezinto ngesikhathi sokuhlola. Ochwepheshe bokwenza ngcono umhlaba basebenzisa amaphampu asetshenzisiwe njengezikhali zokubola ze-jet grouting, ukuhlanganiswa komhlabathi, kanye nezinhlelo zokucindezela eziphakeme lapho okudingwa ukubekezela. Ukuphishekela amaphampu asetshenzisiwe ngokuvamile kwenzeka ngezinsuku ezingu-3.0 kuya ku-12.0 zemitha ngezilinganiso zangaphandle eziyinkomba zokuhlanganisa ezizinzile ezingu-76 mm kuya ku-1,220 mm, kuye ngezincazelo zomphakathi wesikhangiso kanye nezinhlelo zokubuyisela. Amaphampu abuyiselwe ngokuba ama-bundles ahlukanisiwe, anokuphathwa kokuvikela ukuze kuncishiswe ukuvuvukala kanye nomonakalo wezobuchwepheshe ngesikhathi sokuhamba nokugcina. Ukuze kusebenze endaweni, kudinga imishini efanele yokuphatha (ama-cranes, amahoisting rigs) kanye nesitoreji emhlabeni ophakame, opholile nolungiselwe kahle. Ukuphathwa kwesisindo nemiphumela yokuhlola kwe-thread kubalulekile ngaphambi kokufakwa ukuze kuqinisekiswe ukuhambisana nezixhumi zokubola noma zokushaya izinduku. Izinguquko eziyinhloko zihlanganisa ukufakwa okuthiwa i-flush-joint casing (okungafani ngokuphelele ngenxa yokucindezela okujule nezokudiliza), ukufakwa okulwasa kwezinhlelo ezijwayelekile ze-rotary, kanye nezindawo ezisemqoka ezilungiselelwe ukuthola ukuncipha kokuqinisa nokunciphisa ukuhamba. I-API ne-EN zihlukanisa amaphampu ngokwezigaba (K55, N80, P110 efanayo) kanye nezilinganiso zokuphumela/ukuphuka, kuqinisekisa ukuthi ukukhethwa kuhambisana nezilindelo ze-hydrostatic nezidingo ze-torque. Ezinye izinqwaba ezivuselelekayo zifaka ama-coatings avikela ukuvuvukala noma izitsha ze-epoxy zangaphakathi zezindawo ezihlasela kakhulu. Izinkomba zokukhetha zigxila kumandla okugeqeza okuqondile, ukujula komhlaba, ububanzi bokuvuvukala bangaphandle (ngokuvamile <10% yokuncipha okuyavunyelwe), ukuhamba kwe-thread (ukuhlola okubukwayo kanye nezidingo zokuhlola izixhumi), kanye nokufanelana nezinsiza ze-rig ezikhona. Omatasa bezobuchwepheshe baqinisekisa umlando wokusebenza kwangaphambilini, nezinsizakusebenza zokuhlola ezingaphuli (ukulinganiswa kwezinduku, ukuhlola kwezinto ezimagnethic) ukuze kuqinisekiswe imithwalo yokuphila ephephile kanye nezinga lokubola. Ukuhambisana ne-ASTM A252 (Steel Casing), EN 10208 (amaphampu amasha), kanye ne-API 5A/5AX ziqinisekisa ukuzinza kwesakhiwo. Ukuqinisekiswa kwe-ISO 9001 kwabathengisi bokubuyisela nezincwadi zokulandela izinto kuqinisa ukwethenjwa kwekhwalithi kanye nokuvunyelwa kokulawulwa ezigabeni ze-EU, North America, kanye nemikhakha yamazwe angaphandle.
