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 Scope1. 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 ntom ntom nrog 30-60 tus qauv nkag mus thiab cov pob zeb mos nrog saturated uniaxial compressive zog tsis tshaj 10 MPa.2. 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 deviationist tsis siab tshaj 1/300 thaum nws siv los ua lub zog ntawm sab hauv thiab sab nrauv trench phab ntsa. phab ntsa hauv av);
3. Phab ntsa thickness 550-950 mm;
4. Cov cement 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 ncav cuag 1 × 10-6 cm / s rau 1 × 10-7 cm / s hauv cov av xuab zeb;
6. Qhov sib txawv ntawm cov interpolated profiles tuaj yeem muab 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 feem ntau tsis tshaj 12 meters. thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm kev tsim thav duab yog tsawg, nrog zoo stability.
Yog tias koj muaj qhov yuav tsum tau ua ntawm cov tshuab drilling rigs, thov hu rau kom paub meej ntxiv thiab kev sib tham.
