Trench Cutting Re-mixing Deep Wall Tshuab

TRD Method – Txheej txheem txheej txheem
1, Lub hauv paus ntsiab lus: Tom qab cov saw hlau txiav cov cuab yeej raug txiav vertically thiab tsis tu ncua mus rau qhov tsim qhov tob, nws raug thawb kab rov tav thiab txhaj nrog cov cement slurry los ua ib qho txuas ntxiv, sib npaug thickness thiab seamless cement phab ntsa;
2, Ntxig cov khoom siv tseem ceeb (H-zoo li cov hlau, thiab lwm yam) rau hauv cov cement sib xyaw phab ntsa ntawm cov thickness sib npaug los tsim cov khoom sib txuas thiab cov qauv dej nres.

TRD Method – Nta thiab Scope
1. Nws muaj feem xyuam rau cov av nplaum, xuab zeb, gravel thiab gravel txheej, thiab tseem muaj kev siv tau zoo hauv cov xuab zeb tuab nrog 30-60 tus qauv nkag mus thiab cov pob zeb mos nrog cov saturated uniaxial compressive zog tsis tshaj 10 MPa2. Qhov tob ntawm phab ntsa tiav tuaj yeem ncav cuag 70 meters, thiab qhov kev sib txawv ntawm qhov ntsug yuav tsum tsis txhob ntau dua 1/250 (thaum TRD verticality sib txawv tsis ntau dua 1/300 thaum nws siv los ua lub zog ntawm sab hauv thiab sab nrauv trench phab ntsa. ntawm phab ntsa hauv av),
3. Phab ntsa thickness 550-950 mm
4. Cov cement yog sib tov sib xyaw, thiab qhov tsis muaj zog compressive yog 0.5-2.5MPa;
5. Cov phab ntsa muaj cov dej tsis zoo, thiab cov permeability coefficient tuaj yeem ua tau
ncav cuag 1 × 10-6 cm / st 1 × 10-7 cm / s hauv cov av xuab zeb; 6. Qhov sib nrug ntawm qhov sib txuas ntawm cov profiles tuaj yeem sib npaug nrog qhov sib npaug sib npaug, thiab qhov rigidity ntawm lub thawv yog ntau yam sib xws; 7. Qhov siab tshaj plaws ntawm kev tsim kho tshuab yog feem ntau tsis ntau tshaj 12 meters, thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm kev tsim thav duab yog qhov tsawg, nrog kev ruaj ntseg zoo.
