(2) Nws raug nquahu kom siv qhov ntev auger laum qhov, qhov ntev auger laum tuaj yeem xyaum los ntawm cov huab cua hnyav granite txheej, siab zog nyuaj interlayer lossis pob zeb cais, ntsug sib txawv yuav tsum tsis txhob ntau tshaj 0.5%;
(3) Thaum tus tsav lub qhov yuav tsum tau dhau los ntawm cov nyuaj nyuaj, lub pilot qhov taub yuav tsum yog pawg kab D-20mm; Thaum tus tsav lub qhov nkag mus rau hauv lub pob zeb weathered nrog ntau hits, qhov sib npaug ntawm txoj kab uas hla yuav siv tau;
(4) Lub qhov pilot yuav tsum nkag mus rau 1m ntawm cov kabmob txheej kom txo tau cov nyhuv squeezing, thiab qhov pilot qhov taub yuav tsum yog D-50mm ntawm pawg kab;
(5) Rau qhov xwm txheej ntawm "ceev faj siv ntawm qhov chaw" ntawm cov yeeb nkab pawg xws li inclined bearing txheej, nyias txheej ntawm cov av tsis muaj zog thiab pom tseeb cov av squeezing nyhuv, txoj kev tsim kho ntawm lub qhov yuav tsum tau ua ke nrog cov hom ntawm qhov chaw, pawg. txoj kev tsav tsheb thiab daim ntawv qhia txog pawg los txiav txim qhov kev tsim kho.
Lus Cim: Pre-drilling (pilot qhov) yog ib qho kev ntsuas uas siv rau hauv cov yeeb nkab kev tsim kho kom nkag mus rau cov txheej txheem nyuaj thiab cov pob zeb sib cais, txo cov nyhuv squeezing, thiab nce qhov tob ntawm pawg. Raws li kev paub txog kev tsim vaj tsev thiab qhov xwm txheej tiag tiag, txoj kab uas hla ntawm lub qhov tsav yuav tsum tau txiav txim siab raws li cov av ntawm qhov chaw, pawg kab, pawg tuab thiab lwm yam, qhov dav ntawm lub qhov taub feem ntau tuaj yeem yog 10cm lossis 5cm me dua li cov yeeb nkab. pawg txoj kab uas hla, yog tias tsim nyog, nws kuj tuaj yeem sib npaug ntawm txoj kab uas hla ntawm lub qhov. Nyob rau hauv ib txwm muaj xwm txheej, qhov tob ntawm tus tsav lub qhov yuav tsum tsis txhob ntau tshaj 12m, txiav txim siab hais tias lub ntsug sib txawv ntawm lub pilot qhov tsis yooj yim los tswj thaum lub pilot qhov tob heev, nws yog ib qhov nyuaj rau kho qhov sib txawv thaum lub qhov pilot yog skewed. , thiab nws yog ib qho yooj yim los rhuav tshem lub cev. Thaum tus tsav lub qhov nkag mus rau hauv lub pob zeb weathered nrog ntau hits, nws yuav tsum tau muab sau tseg tias txawm yog hais tias tus tsav lub qhov taub yog loj (pile txoj kab uas hla D-20mm), nws tseem yuav nyuaj rau tsav pawg mus rau hauv qab ntawm lub qhov. (uas yog, "dab pawg"). Yog tias tsim nyog, qhov sib npaug ntawm txoj kab uas hla yuav siv tau; Thaum cov dej tau sau rau hauv qhov kev sim, nws raug nquahu kom siv lub qhov ncauj qhib qhov ncauj. Yog tias siv lub kaw lus kaw lus, qhov teeb meem tsis zoo ntawm kev dai pawg yuav tshwm sim.
(3) Thaum tus tsav lub qhov yuav tsum tau dhau los ntawm cov nyuaj nyuaj, lub pilot qhov taub yuav tsum yog pawg kab D-20mm; Thaum tus tsav lub qhov nkag mus rau hauv lub pob zeb weathered nrog ntau hits, qhov sib npaug ntawm txoj kab uas hla yuav siv tau;
(4) Lub qhov pilot yuav tsum nkag mus rau 1m ntawm cov kabmob txheej kom txo tau cov nyhuv squeezing, thiab qhov pilot qhov taub yuav tsum yog D-50mm ntawm pawg kab;
(5) Rau qhov xwm txheej ntawm "ceev faj siv ntawm qhov chaw" ntawm cov yeeb nkab pawg xws li inclined bearing txheej, nyias txheej ntawm cov av tsis muaj zog thiab pom tseeb cov av squeezing nyhuv, txoj kev tsim kho ntawm lub qhov yuav tsum tau ua ke nrog cov hom ntawm qhov chaw, pawg. txoj kev tsav tsheb thiab daim ntawv qhia txog pawg los txiav txim qhov kev tsim kho.
