(1) Ububanzi bomngxuma wokulingwa akufunekanga bube ngaphezu kwe-0.9 kuphinda-phindwe ka-0.9 ububanzi bengqumba yombhobho, kwaye amanyathelo kufuneka athathwe ukuthintela ukudilika komngxuma, kwaye ubunzulu bomngxuma wokulingwa akufunekanga budlule kwi-12m;
(2) Kucetyiswa ukuba usebenzise umngxuma omde we-auger drill, i-auger drill ende inokubhoboza umaleko wegranite oqinileyo, amandla aphezulu aqinileyo okanye ilitye elizimeleyo, ukutenxa ngokuthe nkqo akufuneki kube mkhulu kune-0.5%;

(3) Xa umngxuma wokulinga kufuneka udlule kwisandwich eqinileyo, idiameter ye pilot hole kufuneka ibe yingqumba ye-D-20mm; Xa umngxuma wokulingwa ungena kwilitye elinesimo sezulu esinenani eliphezulu lokubetha, umngxuma wokulinga olinganayo ungasetyenziswa;
(4) Umngxuma wokulinga kufuneka ungene kwi-1m yomaleko wokuthwala ukunciphisa isiphumo sokucudisa, kunye nedayamitha yomngxuma wokulinga kufuneka ibe yi-D-50mm yobubanzi bemfumba;
(5) Kwimeko "yokusetyenziswa ngononophelo kwendawo" yeemfumba zemibhobho enjengomaleko wokuthwala otyekelelekileyo, umaleko womhlaba obhityileyo ongenabuthathaka kunye nefuthe elicacileyo lokucudisa umhlaba, indlela yokwakhiwa komngxuma wokulinga kufuneka idityaniswe nohlobo lwesiza, imfumba. indlela yokuqhuba kunye nefom yengcebiso yemfumba ukumisela imilinganiselo yokwakha.
Qaphela: I-pre-drilling (i-pilot hole) ngumlinganiselo oqhelekileyo osetyenziselwa ukwakhiwa kwemfumba yombhobho ukungena kwii-interlayers ezinzima kunye namatye ahlukeneyo, ukunciphisa umphumo wokukhama, kunye nokwandisa ubunzulu bemfumba. Ngokwamava obunjineli kunye nemeko yokwenyani, ububanzi bomngxuma wokulingwa kufuneka bugqitywe ngokwemeko yomhlaba wesiza, idiameter yengqumba, ingxinano yemfumba kunye nezinye izinto, ububanzi bomngxuma wokulingwa bunokuba yi-10cm okanye i-5cm encinci kunombhobho. ingqumba ububanzi, ukuba kuyimfuneko, inokuba kwakhona ilingane ububanzi umngxuma pilot. Phantsi kweemeko eziqhelekileyo, ubunzulu bomngxuma wokulinga akufunekanga budlule kwi-12m, kuthathelwa ingqalelo ukuba ukutenxa ngokuthe nkqo komngxuma wokulingwa akulula ukuwulawula xa umngxuma wokulingwa unzulu kakhulu, kunzima ukulungisa ukutenxa xa umngxuma wokulinga ujijelwe. , kwaye kulula ukuqhekeza umzimba wemfumba. Xa umngxuma wokulingwa ungena kwilitye elinesimo sezulu esinenani eliphezulu lokubetha, kufuneka kuqatshelwe ukuba nangona i-pilot ye-pilot ye-diameter inkulu (i-pile diameter ye-D-20mm), kusenokuba nzima ukuqhuba imfumba ukuya ezantsi komngxuma. (oko kukuthi, “imfumba ejingayo”). Ukuba kuyimfuneko, imingxuma yokulinga elinganayo ingasetyenziswa; Xa amanzi eqokelelwe kumngxuma wokulingwa, kuyacetyiswa ukuba usebenzise incam yemfumba yomlomo ovulekileyo. Ukuba i-tip yemfumba etywiniweyo isetyenzisiwe, imeko engathandekiyo yokuxhoma ingenzeka.
