Txoj kev tsim kho ntawm peb-seem geonet

Geonet peb-seem yog ib yam khoom siv feem ntau siv rau hauv kev tiv thaiv kev nqes hav thiab kev kho dua tshiab ntawm ecological. Yog li, nws cov txheej txheem tsim kho yog dab tsi?

1. Kev npaj lub hauv paus ua ntej kev tsim kho

Yuav tsum tau ua kev soj ntsuam geological thiab kev kho qhov ntxhab ua ntej kev tsim kho. Nws yog ib qho tsim nyog los ua qhov kev ntsuas laser peb-seem ntawm qhov ntxhab kom paub meej qhov piv ntawm qhov ntxhab, hom geotechnical thiab qhov chaw ntawm qhov chaw plam.

2. Tso cov geonet peb-seem

1, Tsim qauv ntawm lub kaw lus anchoring

Lub kaw lus anchoring yog qhov tseem ceeb rau kev sib koom tes ntawm 3D geonet thiab nqes hav. Kev siv dav dav U Ua ke anchoring txoj kev ntawm seem hlau ntsia hlau thiab xyoob ntsia hlau: qhov dav khawb ntawm sab saum toj ntawm nqes hav yog 30 cm, Sib sib zog nqus 20 cm Faus qhov kawg ntawm lub mesh rau hauv qhov av thiab rov qab sau nws C20 Concrete; Thaj chaw nqes hav yog faib raws li cov duab paj plum teeb tsa Ф8mm Rebar anchors, qhov sib nrug 1.0-1.5 m, Anchoring tob tsis tsawg dua 40 cm。

2, Kev tswj cov txheej txheem sib koom ua ke

Qhov dav ntawm qhov sib tshooj ntawm txoj kab hla yuav tsum ≥20cm, qhov sib tshooj ntev yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "nias cia", uas yog, lub mesh sab saud yuav tsum npog ntug ntawm lub mesh qis dua 10-15 cm. Ob kab raug saws ntawm cov pob qij txha U Hom ntsia hlau kho, qhov deb ntawm tus ntsia hlau yog encrypted rau 50 cm.

3, Kev tsim kho ntawm backfill overburden

Qhov kev thauj khoom ntau dhau yuav tsum ua tiav peb zaug: thawj qhov rov qab sau 8-10 cm Cov av tuab thiab zoo yuav tsum tau nias los ntawm lub tshuab me me; Cov chiv qeeb qeeb raug sib xyaw thaum lub sijhawm rov qab sau thib ob (N: P: K = 15: 15: 15) Thiab tus neeg sawv cev khaws dej, qhov sib xyaw sib xyaw yog tswj ntawm 3 ‰; Qhov tuab ntawm txheej npog kawg yuav tsum ncav cuag 120% ntawm tus nqi tsim, Xyuas kom tseeb tias lub hnab net tau qhwv tag.

3. Kev tsim cov nroj tsuag txheej

1, Qhov sib piv ntawm cov khoom siv

Cov txheej txheej hauv qab yuav tsum ua tau raws li peb yam kev cai ntawm "kev khaws dej-kev nkag tau ntawm huab cua-kev noj haus". Cov mis no muaj 60% ntawm cov av humus, 20% ntawm cov av peat, 15% ntawm cov chiv organic, 5% ntawm cov khoom sib txuas thiab 0.5% ntawm cov tshuaj polyacrylamide uas khaws dej.

2, Cov txheej txheem kev tshuaj tsuag noob

Thaum siv lub tshuab txau hydraulic rau kev tsim kho, cov kev ntsuas hauv qab no yuav tsum tau tswj: qhov deb ntawm lub nozzle thiab qhov chaw nqes hav yog 0.8-1.2 m, Kev txhaj tshuaj siab 0.3-0.5 MPa, Noob ceev 25-30 g / m². Qhov piv nqes hav > 1: 0.75 Rau cov nqes hav ntxhab, 2% ntoo fiber yuav tsum tau ntxiv ua cov khoom siv nqa khoom. Hauv thaj chaw tiaj tiaj thiab alpine, Cov txheej txheem cog qoob loo sib xyaw ntawm cov nyom txias xws li bluegrass thiab purple fescue nrog cov noob ntoo xws li Caragana korshinskii thiab seabuckthorn tuaj yeem siv, uas tuaj yeem npog cov nroj tsuag sai sai.

3. Kev tswj hwm kev saib xyuas

Lub voj voog txij nkawm yuav tsum kav ntev mus txog thaum cov nroj tsuag npog ntau dua 80%. Tshuaj tsuag 2-3 zaug hauv ib hnub thaum pib, thiab qhov ntau ntawm cov dej txhua zaus tsuas yog txwv tsis pub ntws; Cov kua chiv (concentration 0.5%) tau muab tshuaj rau saum ib hlis ib zaug tom qab lub tiaj tiaj tau tsim. Hais txog kev tswj kab mob thiab kab tsuag, cov tshuaj siv tshuaj lom neeg xws li matrine thiab azadirachtin yog siv los tiv thaiv kev puas tsuaj ntawm cov kab mob hauv av los ntawm cov tshuaj lom neeg.

4. Cov ntsiab lus tseem ceeb ntawm kev tswj xyuas zoo

Tsim kom muaj peb theem kev tshuaj xyuas zoo: xyuas lub zog tensile thaum cov ntaub ntawv nkag mus rau hauv qhov chaw (≥15kN / m) 、 Mesh qhov loj me sib txawv (± 5%) Thiab lwm yam kev ntsuas; Thaum lub sijhawm tsim kho, ib chav kuaj pom tau teeb tsa txhua 200 square meters, thiab lub zog anchorage tau txheeb xyuas los ntawm kev sim rub tawm; 6 kauj ruam yuav tsum tau ua thaum lub sijhawm ua tiav kev saib xyuas txhua hli, tsom mus rau kev npog cov nroj tsuag, cov av modulus thiab lwm yam cim.
