Kev tsim kho txheej txheem khiav:
Kev npaj kev tsim kho (cov khoom siv thauj mus los thiab kev teeb tsa) → kev kho mob hauv paus (kev tu) → geogrid nteg (ntev txheej txheem thiab sib tshooj dav) → muab tub lim (txoj kev thiab particle loj) → dov daim phiaj → qis daim phiaj nteg.
Txoj kev tsim kho:
① Kev kho mob hauv paus
Ua ntej, cov txheej hauv qab yuav tsum tau leveled thiab dov.Lub flatness yuav tsum tsis txhob ntau tshaj 15 hli, thiab lub compactness yuav tsum tau raws li qhov yuav tsum tau tsim.Qhov saum npoo yuav tsum tsis muaj tawv protrusions xws li pob zeb thiab pob zeb thaiv.
② Geogrid tso
A. Thaum khaws cia thiab tso cov geogrid, tsis txhob raug tshav ntuj thiab raug lub sij hawm ntev kom tsis txhob muaj kev ua haujlwm tsis zoo.
b.Lub nteg yuav tsum tau perpendicular mus rau txoj kab kev taw qhia, lub lapping yuav tsum tau raws li qhov yuav tsum tau ntawm tus tsim drawings, thiab kev sib txuas yuav tsum ruaj.Lub zog ntawm kev sib txuas hauv kev ntxhov siab yuav tsum tsis txhob tsawg dua qhov tsim tensile lub zog ntawm cov khoom, thiab qhov sib tshooj ntev yuav tsum tsis pub tsawg tshaj 20 cm.
c.Qhov zoo ntawm geogrid yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov qauv tsim.
d.Kev tsim kho yuav tsum tsis tu ncua tsis muaj distortion, wrinkle thiab sib tshooj.Daim phiaj yuav tsum tensioned kom nws dais lub zog.Cov kab sib chaws yuav tsum tau tensioned manually kom nws zoo ib yam, tiaj tus thiab nyob ze rau qhov qis bearing nto.Daim phiaj yuav tsum tau kho nrog pins thiab lwm yam kev ntsuas.
e.Rau lub geogrid, cov kev taw qhia ntawm lub qhov ntev yuav tsum ua raws li cov kev taw qhia ntawm kab hla ntu, thiab geogrid yuav tsum ncaj thiab theem.Qhov kawg grating yuav tsum tau kho raws li tus qauv tsim.
f.Sau cov geogrid hauv lub sijhawm tom qab paving, thiab lub sijhawm yuav tsum tsis pub tshaj 48 teev kom tsis txhob raug tshav ntuj ncaj qha.
③ Filler
Tom qab lub grating yog paving, nws yuav tsum tau sau nyob rau hauv lub sij hawm.Lub filling yuav tsum tau nqa tawm symmetrically raws li lub hauv paus ntsiab lus ntawm "ob sab ua ntej, ces qhov nruab nrab".Nws yog nruj me ntsis txwv tsis pub sau nruab nrab ntawm lub embankment ua ntej.Cov muab tub lim tsis pub ncaj qha mus rub tawm ntawm geogrid, tab sis yuav tsum tau muab tshem tawm ntawm cov av paving, thiab qhov siab ntawm qhov siab tsis tshaj 1m.Tag nrho cov tsheb thiab cov tshuab tsim kho yuav tsum tsis txhob taug kev ncaj qha rau ntawm qhov chaw geogrid, tab sis tsuas yog nyob rau hauv txoj kab nqes.
④ Roll up grille
Tom qab thawj txheej ntawm sau mus txog qhov predetermined thickness thiab dov mus rau qhov tsim compactness, daim phiaj yuav tsum tau dov rov qab rau 2m thiab khi rau yav dhau los txheej ntawm geogrid, thiab lub geogrid yuav tsum manually trimmed thiab anchored.Sab nrauv ntawm yob kawg yuav tsum tau rov qab rau 1m los tiv thaiv kab sib chaws thiab tiv thaiv kev puas tsuaj ntawm tib neeg.
⑤ Ib txheej ntawm geogrid yuav tsum tau pav raws li cov txheej txheem saum toj no, thiab lwm cov txheej ntawm geogrid yuav tsum tau pav raws li tib txoj kev.Tom qab cov phiajcim tau ua tiav, lub embankment filling yuav pib.
Kev ceev faj txog kev tsim kho:
① Kev taw qhia ntawm lub zog siab tshaj plaws ntawm daim phiaj yuav tsum ua raws li cov kev taw qhia ntawm qhov siab tshaj plaws.
② Lub tsheb hnyav yuav tsum tsis txhob tsav ncaj qha rau ntawm qhov chaw geogrid.
③ Tus nqi txiav thiab txiav tus lej ntawm geogrid yuav tsum raug txo kom tsawg kom tsis txhob pov tseg.
④ Thaum lub sij hawm tsim kho nyob rau hauv lub caij txias, lub geogrid yuav nyuaj, thiab nws yog ib qho yooj yim rau txiav tes thiab so hauv caug.Ua tib zoo saib xyuas kev nyab xeeb.
