1. Ua ntej, siv lub polisher los txhuam cov kab nrib pleb nrog qhov dav ntawm 5 cm ntawm ob sab, thiab tom qab ntawd ntxuav cov kab nrib pleb nrog acetone. Yuav tsum tsis muaj roj, plua plav, thiab lwm yam ntawm lub interface.
2. Rau cov kab nrib pleb uas muaj qhov tob tshaj li 5 hli, saturate nrog epoxy resin nyias kua, qhuav thiab solidify, thiab ces txhuam cov epoxy resin cement. Qhov piv ntawm epoxy resin rau cov kua nyias yog epoxy resin: diluent: curing agent 1:0.4:0.25. Qhov piv ntawm cov khoom nyias nyias tuaj yeem nkag mus tob rau hauv lub hauv paus ntawm cov kab nrib pleb. Nws cov qauv muaj zog thiab tuaj yeem sau cov kab nrib pleb.
3. Rau cov kab nrib pleb uas muaj qhov tob tshaj 5 cm, faus grouting nozzles ntawm qhov ntev ntawm 30 mus rau 50 cm, thiab tom qab ntawd siv epoxy resin cement los kaw cov kab nrib pleb nrog qhov dav sealing tsis pub tsawg dua 5 cm. Epoxy resin cement seals cov kab nrib pleb, ua ntej kom kaw cov kab nrib pleb, thiab thib ob los npaj rau grouting. Kev xaiv ntawm qhov chaw rau lub embedded grouting nozzle yog qhov tseem ceeb tshwj xeeb. Qhov no yuav tsum tau txiav txim siab raws li qhov ntev, qhov tob, kev taw qhia, cov duab, thiab lwm yam ntawm cov pob zeb tawg. Feem ntau, nws yuav tsum xaiv cov ntsiab lus ntawm ob qho kawg ntawm qhov tawg thiab qhov khoob thiab cov khoom kom ntseeg tau tias cov grout tuaj yeem ncav cuag txhua qhov sib txawv los ua lub luag haujlwm ntawm kev txhawb nqa thiab kev tiv thaiv tawg.
4. Tom qab cov epoxy resin cement yog qhuav tag, yuav tsum tau ua ib qho kev ntsuas roj los xyuas qhov tseeb ntawm slurry inlet, kua qhov hluav taws xob, thiab tawg sealing. Siv 4 ㎏ / ㎝ 2 lub siab cua kom tawm tswv yim los ntawm lub qhov grouting. Yog tias cov roj tso tawm los ntawm lub qhov hluav taws xob ua kua thiab tsis muaj cua nkag hauv cov cement sealing thiab lwm qhov hluav taws xob tawg, nws txhais tau hais tias lub qhov hluav taws xob tawg thiab lub qhov hluav taws xob tau teeb tsa kom raug, thiab cov cement sealing yog txhim khu kev qha. Kaw lub qhov hluav taws xob ua kua kom nce siab hauv qhov tawg mus rau 4 ㎏ / ㎝ 2 thiab tuav lub siab rau 2 feeb. Yog tias tsis muaj cua nkag, nws yog qhov qub. Yog tias huab cua ntws los ntawm cov cement tom qab qhov cua thiab qhov siab nce, nws yuav tsum tau muab rov qab. Yog tias huab cua tso tawm los ntawm ntau tshaj 2 lub qhov hluav taws xob tom qab qhov cua thiab qhov siab nce, nws txhais tau hais tias qhov tawg txuas nrog ntau dua 2 qhov tawg. Nyob rau lub sijhawm no, cov dej xau tawm yuav tsum raug kaw kom txog thaum tsis muaj cua nkag thiab lub siab tuaj yeem tswj tau, thiab cov ntaub ntawv thiab cov cim yuav tsum tau ua. Tom qab qhov cua thiab qhov siab nce, tsis muaj roj tso tawm los ntawm lub qhov hluav taws xob ua kua. Tej zaum nws yuav yog qhov tawg channel raug thaiv thaum lub sij hawm cement sealing txheej txheem. Nyob rau lub sijhawm no, lub qhov hluav taws xob ua kua thiab qhov chaw nres nkoj yuav tsum tau muab ntxiv rau ntawm qhov tsim nyog ntawm qhov tawg hauv ntu no. Raws li txoj cai, nws tau ua kom ntseeg tau tias tag nrho cov seem ntawm qhov tawg muaj qhov nkag thiab qhov hluav taws xob, tuaj yeem tswj xyuas qhov siab, thiab tsis xau.
5. Tom qab dhau qhov kev sim roj, siv epoxy resin slurry rau siab grouting. Cov cua siab rau grouting yuav tsum tsis pub tsawg tshaj 4㎏/㎝2.
6. Thaum grouting, xyuam xim rau cov kua tso tawm los ntawm grouting nozzle. Tom qab paub meej tias lub tshuab nqus tsev yog tag nrho, kaw lub qhov hluav taws xob ntawm lub qhov hluav taws xob, ua kom lub siab mus rau 4 kg / cm2, tswj lub siab tsis pub tsawg tshaj 5 feeb, thiab tom qab ntawd tos kom nws qhuav lawm. Lub sijhawm ziab ntawm ntuj yuav tsum yog 72 teev.
7. Tshawb xyuas seb puas muaj kev cuam tshuam hauv kev kho qhov tawg.
8. Ntxuav lub grouting nozzle thiab du cov epoxy resin kua nplaum protruding los ntawm cov pob zeb nto.
