Indlela yokwakha ye-geonet enemilinganiselo emithathu

I-geonet enemilinganiselo emithathu sisixhobo esisetyenziswa kakhulu kwicandelo lokukhusela amathambeka kunye nokubuyiselwa kwendalo. Ngoko ke, zeziphi iindlela zokwakha kwayo?

1. Ukulungiswa kwesiseko ngaphambi kokwakhiwa

Uphando lwejografi kunye nonyango lwethambeka kufuneka lwenziwe ngaphambi kokuba kwakhiwe. Kubalulekile ukwenza iskena selaser esinemilinganiselo emithathu kwithambeka ukuze kucaciswe umlinganiselo wethambeka, uhlobo lwejografi kunye nendawo yomphezulu onokuthi utyibilike kuyo.

2. Ukubekwa kwe-geonet enamacala amathathu

1, Uyilo lwenkqubo yokuncamathelisa

Inkqubo yokuncamathelisa yeyona nto iphambili kuxinzelelo lwentsebenziswano phakathi kwe-3D geonet kunye ne-slope. Ukusetyenziswa ngokubanzi U Indlela yokuncamathelisa edibeneyo yezikhonkwane zentsimbi yecandelo kunye nezikhonkwane ze-bamboo: ububanzi bokumba phezulu kwe-slope yi-30 cm 、 Ubunzulu yi-20 cm Gcwalisa isiphelo se-mesh kumsele kwaye uyigcwalise nge-backfill C20 Concrete; Indawo ye-slope isasazwa ngokweseti yemilo ye-plum blossom Ф8mm Rebar anchors, isithuba yi-1.0-1.5 m ， Ubunzulu be-anchoring bungabi ngaphantsi kwe-40 cm 。

2, ulawulo lwenkqubo yokudibanisa i-Lap

Ububanzi bokugquma obunqamlezileyo kufuneka bube yi-≥20cm, Ukugquma okude kufuneka kulandele umgaqo othi “cinezela phantsi”, oko kukuthi, i-mesh ephezulu kufuneka igubungele umda we-mesh esezantsi ibe yi-10-15 cm. Imiqolo emibini iyamkelwa kwiindawo ezisemacaleni. Uhlobo lwe-U luqinisa iinzipho, umgama weenzipho ubethelelwe kwi-50 cm.

3. Ukwakhiwa kwe-backfill overburden

Umthwalo ogqithisileyo kufuneka ugqitywe kathathu: indawo yokuqala yokuzalisa emva eyi-8-10 cm. Umhlaba otyebileyo nocolekileyo kufuneka uqiniswe yi-compactor encinci; Isichumisi esikhupha kancinci sixutywa ngexesha lokuzalisa emva kwesibini (N:P:K=15:15:15）Kunye nearhente yokugcina amanzi, umlinganiselo wokuxuba ulawulwa kwi-3 ‰；Ubukhulu bokugqibela bomaleko wokugquma kufuneka bufikelele kwi-120% yexabiso loyilo, Qinisekisa ukuba ingxowa enethi isongiwe ngokupheleleyo.

3. Ukwakhiwa komaleko wezityalo

1, Umlinganiselo we-substrate

Umaleko we-substrate kufuneka uhlangabezane neemfuno ezintathu "zokugcina amanzi-umoya-ukondla". Le fomula iquka i-60% yomhlaba we-humus, i-20% yomhlaba we-peat, i-15% yesichumiso se-organic, i-5% yesibophelelo kunye ne-0.5% ye-polyacrylamide agent-retaining agent.

2, Iiparameter zobugcisa zokulima imbewu yesitshizi

Xa usebenzisa umatshini wokutshiza nge-hydraulic ekwakheni, ezi parameter zilandelayo kufuneka zilawulwe: umgama phakathi kwe-nozzle kunye nomphezulu we-slope yi-0.8-1.2 m, uxinzelelo lwe-injection yi-0.3-0.5 MPa, Ubuninzi bembewu yi-25-30 g/m². Umlinganiselo we-slope ＞1:0.75 Kwiindawo ezithe tyaba, kufuneka kongezwe i-2% yefayibha yomthi njengezinto zokuthwala. Kwiindawo ezithe tyaba nakwiindawo ezikwi-alpine, inkqubo yokutyala exutyiweyo yeentlobo zengca zexesha elibandayo ezifana ne-bluegrass kunye ne-purple fescue kunye nembewu yezihlahla ezifana neCaragana korshinskii kunye ne-seabuckthorn ingasetyenziswa, enokugubungela izityalo ngokukhawuleza.

3, Inkqubo yolawulo loLondolozo

Umjikelo wolondolozo kufuneka uhlale ude izinga lokugubungela izityalo lifikelele ngaphezulu kwama-80%. Futha amaxesha ama-2-3 ngemini kwinqanaba lokuqala, kwaye umlinganiselo wamanzi ixesha ngalinye ulinganiselwe ekungangeni manzi; Isichumisi esimanzi (uxinzelelo lwe-0.5%) sasigqunywa kanye ngenyanga emva kokuba iflethi yenziwe. Ngokuphathelele izifo kunye nolawulo lwezinambuzane, amalungiselelo ebhayoloji anjenge-matrine kunye ne-azadirachtin asetyenziswa ngokukhethekileyo. I-Agent yokuthintela ukonakala kweentsholongwane zomhlaba ezibangelwa ziikhemikhali.

4. Amanqaku aphambili olawulo lomgangatho

Misela inkqubo yokuhlola umgangatho enamanqanaba amathathu: jonga amandla okutsalwa xa izinto zingena kwindawo (≥15kN/m）、 Ukuphambuka kobukhulu beMesh (±5%) kunye nezinye iiparameter; Ngexesha lenkqubo yokwakha, iyunithi yokuchonga isetiwe rhoqo kwiimitha zesikwere ezingama-200, kwaye amandla okubambelela aqinisekiswa ngovavanyo lokutsalwa; amanyathelo ama-6 kufuneka enziwe ngexesha lokwamkelwa kokugqitywa Ukubeka esweni rhoqo ngenyanga, kugxilwe ekugubungeleni izityalo, imodulus yokukhukuliseka komhlaba kunye nezinye izalathisi.
