Txheej txheem cej luam ntawm lub thauj tog rau nkoj hollow hlau tuav
Thauj tog rau nkoj Hollow hlau cov tuav tau tsim hauv cov ntu nrog cov qauv ntev ntawm 2.0, 3.0 lossis 4.0 m. Cov txheej txheem txheej txheej ntawm lub hollow hlau tuav ranges los ntawm 30.0 hli rau 127.0 hli. Yog tias tsim nyog, hollow hlau cov tuav txuas nrog coupling txiv ntoo. Qhov sib txawv ntawm cov khoom txi laum uas yog siv nyob ntawm cov av lossis pob zeb loj. Ib qho khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob ntawm qhov chaw uas muaj kev coj tus cwj pwm zoo ib yam nkaus thiab khoov. Qhov tshwm sim yog qhov ntau dua buckling thiab flexural ruaj ruaj rau tib tus nqi ntawm cov hlau.

Cov ntawv thov ntawm tus kheej drilling anchor pas nrig
Nyob rau hauv xyoo tas los no, nrog rau kev nce qib ntawm Geotechnical, drilling cov khoom tau raug hloov kho tas li thiab tsim tau. Nyob rau tib lub sijhawm, cov nqi tu menyuam thiab cov ntiav qev tau nce ntxiv, thiab cov cai ua rau lub sijhawm tsim kom muaj kev nce zuj zus. Tsis tas li ntawd, kev siv tus kheej drilling hollow rau hauv lub nkoj hauv geological cov kev mob siab mus rau collapse cuam tshuam tau zoo heev anchoring cuam tshuam. Cov laj thawj no tau coj mus rau ntau qhov kev thov cuam tshuam ntawm tus kheej drilling hollow thauj tog rau nkoj lub pas nrig. SELF DRILLING HOLLOW tog thauj tog rau nkoj lub pas nrig feem ntau yog siv nyob rau hauv cov xwm txheej hauv qab no:
1. Siv los ua prestressed anchor pas nrig: Siv hauv cov xwm txheej xws li toj, av khawb, thiab anti ntab los hloov thauj tog rau nkoj cable. SECTING HOLLOW tog rau lub tog raj hluav taws xob yog drilled rau qhov yuav tsum tau tob, thiab tom qab ntawd dhau los yog nqa tawm. Tom qab solidification, nro yog siv;
2. Siv raws li Micropiles: SELF DRILLING HOLDLE cog rau hauv lub foundations, cov hauv paus tsev loj heev, cheiding phab ntsa rooj zaum, che chees hauv lub hauv paus, thiab lwm yam;
3. Siv rau hauv av tes: feem ntau yog siv rau kev txhawb nqa txoj kab sib txuas, thiab tuaj yeem siv rau kev txhawb nqa txoj kab nqes ntxhab;
4. Siv rau pob zeb ntsia thawv: Hauv qee cov pob zeb hauv pob zeb lossis kev tsim kho tus kheej, tus kheej drilling lub pob zeb loj lossis kev txhim kho lub pob zeb ua ke txhawm rau txhim kho lawv cov kev ruaj khov. Piv txwv li, foob pob zeb ntawm txoj kev loj thiab kev sib tsoo uas tau sib tsoo tuaj yeem siv tau rau cov khoom siv hluav taws xob kuj tseem tuaj yeem hloov pauv rau kev siv cov xoob xoob nyob ntawm kev xoob xoob qhov chaw qhib;
5. Kev txhawb kev ua haujlwm lossis kev tswj hwm kev puas tsuaj. Raws li lub sijhawm txhawb nqa ntawm thawj Geotechnical txhawb nqa kev nce qib, xws li deformation ntawm thawj lub hauv paus, thiab upft ntawm txoj kev tsheb. SECER DRILLING HOLLOW tog rau lub tog raj hluav taws xob tuaj yeem siv rau cov kab nqes, hauv av, los tiv thaiv qhov tshwm sim, los tiv thaiv qhov tshwm sim ntawm geological kev puas tsuaj.
