Ⅰ. Iinqwaba ezenziwe ngodonga olukhusela udaka
Iipali ezibolileyo zokujikeleza phambili nangasemva: Ukujikeleza phambili kukuba ulwelo lokufunxa luthunyelwa ezantsi komngxuma ngepompo yodaka ngenduku yokubhola, luze lubuyele emhlabeni lusuka ezantsi komngxuma; ulwelo lokufunxa olujikelezayo olubuyela umva luchasene ngqo nendlela yokujikeleza phambili.
1 、 Iimeko zomhlaba ezisebenzayo: umhlaba onodaka, intlabathi, isanti ecolekileyo, isanti ephakathi, isanti erhabaxa, umhlaba onomhlaba omncinci kunye neengqalutye (umxholo ungaphantsi kwama-20%).
2, ububanzi besicelo: ubunjineli bokwakha; ubunjineli beendlela neebhulorho; ubunjineli bukamasipala.
Ukubhola ngePercussiveUmngxumaUkuzalisaInqwaba:Ukubhola ngoomatshini, ukucudiswa kwemibhobho yentsimbi okanye ukugrunjwa ngabantu ukuze kwenziwe imingxunya yeenqwaba
umhlaba wesiseko.
1、Iyasebenzaumhlabaiimeko: umhlaba onodongwe, umhlaba ogudileyo, umhlaba onesihlabathi, umhlaba ogcweleyo, umhlaba oqingqiweyo kunye neengqimba zamatye ezigugileyo.
2, ububanzi besicelo:ubunjineli bokwakha; ubunjineli beendlela neebhulorho; ubunjineli bukamasipala.
(2) I-RotaryUmngxumaUkuzalisaInqwaba:Ukusebenzisa i-drill bit ukujikelezisa i-drill emhlabeni, umngxuma wokugqibela owenziweyo kukuzaliswa kwe-rotary hole.
1、Iyasebenzaumhlabaiimeko: umhlaba onodongwe, umhlaba ogudileyo, umhlaba onesihlabathi, umhlaba ogcweleyo, umhlaba oqingqiweyo kunye neengqimba zamatye ezigugileyo.
2, ububanzi besicelo:isetyenziswa kulwakhiwo lukamasipala, uhola wendlela kunye neebhulorho, ulwakhiwo lwemizi-mveliso nolwaseburhulumenteni, phantsi komhlaba
udonga lwe-diaphragm, ukugcinwa kwamanzi, ukuthintela ukuvuza kwamanzi, ukukhusela ithambeka kunye nezinye izakhiwo zesiseko.
Ⅱ. Iinqwaba ezikruqukileyo ezisetyenzwayo
(1) Ndele I-Auger Ndikruqukile Inqwaba:Gobhoza umngxuma ngesixhobo sokugrumba eside, coca umzantsi womngxuma ukuya kubunzulu boyilo, ubeke phantsi ikheyiji yokuqinisa, uze ugalele isamente kwikholam.
1. Iimeko zomhlaba ezisebenzayo: umhlaba onodaka ongaphezulu kwamanzi, umhlaba onesihlabathi kunye nomhlaba owenziweyo ozaliswe ngokungekho ngqindilili onamahlalutye, oqinileyo
ilitye eliguqukileyo.
2, ububanzi besicelo: izakhiwo zoluntu nezemizi-mveliso ezingaphezulu kwetafile yamanzi yomhlaba odibeneyo ngokubanzi, umhlaba onesihlabathi kunye nesiseko sokulahla inkunkuma esenziwe ngokwenziwa.
(2) Inqwaba ye-grouting esezantsi ekhulayo yomngxuma odiniweyo:Okokuqala, sebenzisa i-bored pile drill bit eqhelekileyo ukuze ulandele indlela yokugrumba ngokubanzi ukuze ugrumbe kumaleko obambe oyilwe ngokobubanzi bomzimba we-pile, uze ukhuphe izixhobo zokugrumba uze ufake i-drill bit eqhelekileyo endaweni yayo nge-expanding bottom drill bit ekhethekileyo ezantsi komngxuma ukuze wenze intloko ekhulayo ngokwandisa ububanzi bomngxuma we-pile.
Okokuqala sebenzisa i-bored pile drill bit eqhelekileyo ukuze ulandele indlela eqhelekileyo yokugrumba ukuze ugrumbe ngokobubanzi bomzimba we-pile ukuya kumaleko we-bearing oyilwe, uze ukhuphe isixhobo sokugrumba, utshintshe i-drill bit eqhelekileyo nge-bottoming bottom-expanding drill bit ekhethekileyo ezantsi komngxuma, uze wandise ububanzi bomzantsi we-pile ukuze wenze intloko yokwandisa.
1、Iimeko zomhlaba ezisebenzayo: umhlaba oqinileyo, oqinileyo wodongwe ongaphezulu kwamanzi kunye nesanti kunye negrabile ezigubungele amatye ngaphezulu koxinano oluphakathi.
2, ububanzi besicelo: izakhiwo zoluntu nezemizi-mveliso ezingaphezulu kwetafile yamanzi yomhlaba odibeneyo ngokubanzi, umhlaba onesihlabathi kunye nesiseko sokulahla inkunkuma esenziwe ngokwenziwa.
