Txheej txheem cej luam ntawm Anchor Hollow Steel Bars
Cov hlau hollow anchor yog tsim ua ntu nrog qhov ntev txheem ntawm 2.0, 3.0 lossis 4.0 m. Lub cheeb tsam sab nraud txheem ntawm cov hlau hollow yog txij li 30.0 mm txog 127.0 mm. Yog tias tsim nyog, cov hlau hollow yuav txuas ntxiv nrog cov txiv ntoo sib txuas. Ntau hom kev siv cov khoom siv sib txawv nyob ntawm hom av lossis pob zeb. Cov hlau hollow zoo dua li cov hlau khov kho nrog tib thaj chaw hla vim nws tus cwj pwm zoo dua hauv kev khoov, ncig thiab khoov. Qhov tshwm sim yog qhov ruaj khov dua thiab khoov dua rau tib cov hlau.

Cov ntawv thov ntawm Tus Kheej Drilling Anchor Rods
Nyob rau xyoo tas los no, nrog rau qhov kev thov nce ntxiv rau kev txhawb nqa geotechnical, cov khoom siv drilling tau hloov kho tshiab thiab tsim kho tas li. Tib lub sijhawm, cov nqi ua haujlwm thiab cov nqi xauj tsev tau nce ntxiv, thiab cov kev xav tau rau lub sijhawm tsim kho tau nce siab. Tsis tas li ntawd, kev siv cov pas nrig hollow anchor tus kheej hauv cov xwm txheej geological uas yuav tawg muaj cov teebmeem anchoring zoo heev. Cov laj thawj no tau ua rau muaj kev siv dav dav ntawm cov pas nrig hollow anchor tus kheej. Cov pas nrig hollow anchor tus kheej feem ntau yog siv rau hauv cov xwm txheej hauv qab no:
1. Siv ua tus pas nrig prestressed: siv rau hauv cov xwm txheej xws li qhov ntxhab, kev khawb av hauv av, thiab tiv thaiv kev ntab los hloov cov xov hlau anchor. Cov pas nrig anchor hollow uas tus kheej tho qhov tob raug tho qhov tob uas xav tau, thiab tom qab ntawd ua tiav grouting. Tom qab khov, kev nruj yog siv;
2. Siv ua micropiles: Cov pas nrig hollow anchor uas koj tus kheej tho tau tuaj yeem tho thiab grouted downwards los ua micropiles, feem ntau siv rau hauv cov chaw tsim hluav taws xob cua, cov chaw tsim hluav taws xob kis, cov chaw tsim kho, cov chaw khaws cia phab ntsa, cov chaw tsim choj, thiab lwm yam;
3. Siv rau cov ntsia hlau av: feem ntau siv rau kev txhawb nqa nqes hav, hloov cov hlau tuav hlau ib txwm muaj, thiab kuj tseem siv tau rau kev txhawb nqa nqes hav tob hauv lub hauv paus;
4. Siv rau cov ntsia hlau pob zeb: Hauv qee qhov chaw pob zeb lossis qhov av uas muaj kev puas tsuaj loj heev lossis kev sib koom ua ke, cov pas nrig hollow anchor uas tus kheej tho qhov tuaj yeem siv rau kev tho thiab grouting los txuas cov pob zeb ua ke kom txhim kho lawv qhov ruaj khov. Piv txwv li, cov chaw pob zeb ntawm txoj kev loj thiab txoj kev tsheb ciav hlau uas yooj yim tawg tuaj yeem ua kom muaj zog, thiab cov kav dej ib txwm muaj kuj tuaj yeem hloov pauv rau kev txhawb nqa ntawm qhov qhib qhov av xoob;
5. Kev txhawb nqa yooj yim lossis kev tswj hwm kev puas tsuaj. Thaum lub sijhawm txhawb nqa ntawm lub kaw lus txhawb nqa geotechnical qub nce ntxiv, cov qauv txhawb nqa no yuav ntsib qee qhov teeb meem uas xav tau kev txhawb nqa lossis kev kho, xws li kev hloov pauv ntawm qhov nqes hav qub, kev sib haum xeeb ntawm lub hauv paus qub, thiab kev tsa ntawm qhov chaw ntawm txoj kev. Cov pas nrig anchor hollow uas tus kheej tho qhov tuaj yeem siv los tho rau hauv qhov nqes hav qub, lub hauv paus, lossis hauv av ntawm txoj kev, thiab lwm yam, rau kev sib xyaw thiab kev sib sau ua ke ntawm cov kab nrib pleb, kom tiv thaiv kev tshwm sim ntawm kev puas tsuaj geological.
