  • Umnatha wokuqinisa indawo yolwakhiwo ukwenzela ukubeka itonela

Inkcazelo emfutshane:

I-mesh yokuqinisa ibhekisela kwi-mesh apho ukuqinisa kuhlelwe ngokuthe tye kwaye ngokuthe nkqo. Inomgama othile kwaye yenza i-engile echanekileyo enye kwenye. Zonke iindlela zokuhlangana kufuneka zidityaniswe ukuze zenze umnatha. Xa ubophelela, iinkcukacha ezahlukeneyo ze-mesh yensimbi kufuneka zikhethwe ngokweemfuno zangempela kunye neemfuno zokuthwala umthwalo.

Uphawu

Yintoni ukuqinisa umnatha?
Ukomelezwa komnatha yinkqubo yokusebenzisa ilaphu locingo lwentsimbi oludityanisiweyo njengento yokuqinisa izinto zekhonkrithi ezinjengama-slabs ekhonkrithi neendonga. Ukuqinisa i-mesh ngokuqhelekileyo kuza kwipatheni yegridi yoxande okanye yesikwere kwaye iveliswa ngamashiti acaba.

1. Okukhethekileyo, ukumelana nokuzamazama komhlaba okulungileyo kunye nokuchasana nokuqhekeka. Isakhiwo se-mesh eyenziwe yimivalo ye-longitudinal kunye nemivalo enqamlezayo ye-mesh yokuqinisa i-welded ngokuqinile. Ukudibanisa kunye ne-anchoring kunye nekhonkrithi kulungile, kwaye amandla ahanjiswa ngokulinganayo kwaye ahanjiswe.
2. Ukusetyenziswa kwe-mesh yokuqinisa ekwakheni kunokugcina inani leentsimbi zetsimbi. Ngokwamava okwenene obunjineli, ukusetyenziswa kwe-mesh yokuqinisa kunokugcina i-30% yokusetyenziswa kwentsimbi yentsimbi, kwaye i-mesh ifana, i-diameter ye-wire ichanekile, kwaye i-mesh i-flat. Emva kokuba i-mesh yokuqinisa ifike kwindawo yokwakha, ingasetyenziselwa ngokuthe ngqo ngaphandle kokucubungula okanye ilahleko.
3. Ukusetyenziswa kwe-mesh yokuqinisa kunokukhawulezisa inkqubela phambili yokwakha kunye nokunciphisa ixesha lokwakha. Emva kokuba i-mesh yokuqinisa ibekwe ngokweemfuno, ikhonkrithi inokugalelwa ngokuthe ngqo, ikhuphe isidingo sokusika kwisayithi, ukubeka, kunye nokubopha enye enye, enceda ukugcina i-50% -70% yexesha.

Isicelo

1. Ukusetyenziswa komnatha wokuqinisa kuhola wendlela yobunjineli besamente kwipavumente yesamente

Ubuncinci bedayamitha kunye nesithuba esiphezulu sokuqinisa umnatha kwipavumente eqinisiweyo iya kuhambelana nemigangatho yangoku yoshishino. Xa kusetyenziswa imivalo yentsimbi eqengqelekayo ebandayo, ububanzi bentsimbi yentsimbi abuyi kuba ngaphantsi kwe-8mm, isithuba sebar yentsimbi yobude asiyi kuba sikhulu kuno-200mm, kwaye isithuba sentsimbi enqamlezileyo asiyi kuba sikhulu kune-300mm. Iintsimbi zetsimbi ezithe nkqo kunye nezithe tyaba zomnxeba odibeneyo kufuneka zibe nobubanzi obufanayo, kwaye ubukhulu bomgangatho okhuselayo wentsimbi yentsimbi akufanele kube ngaphantsi kwama-50mm. Umnatha odityanisiweyo woqiniswa kwipavumente yekhonkrithi eqinisiweyo unokuphunyezwa ngokuhambelana nemigaqo echaphazelekayo yomnatha odityanisiweyo wepavement yekhonkrithi eyomeleziweyo.

2. Ukusetyenziswa kwe-mesh yokuqinisa kubunjineli bebhulorho

Ikakhulu isetyenziswa kwidekhi yebhulorho yendlela yeebhulorho zikamasipala kunye neebhulorho zohola wendlela, ukulungiswa kweedekhi zebhulorho endala, ukuchasana nokuqhekeka kweepiers zebhulorho, njl. njl. Ukwamkelwa komgangatho wamawaka ezicelo zebhulorho eTshayina kubonisa ukuba ukusetyenziswa komnatha odityanisiweyo kunokuphucula ngokubonakalayo umgangatho womgangatho wendlela yendlela yomgangatho webhulorho, ireyithi yokupasa, ukutyeba komgangatho osicaba we-9% iphuculwe, umgangatho webhulorho uphantse wangabinantandabuzo, kwaye isantya sendlela yendlela sinyukile Ngaphezu kwe-50%, icutha ixabiso lokuhamba ngebhulorho malunga ne-10%.

3. Ukusetyenziswa kwe-mesh yokuqinisa kwi-tunnel line

Ngokwemimiselo yesizwe, i-ribbed mesh yokuqinisa kufuneka ifakwe kwi-shotcrete, enceda ekuphuculeni ukucheba kunye nokugoba amandla okudubula, ukuphucula ukuxhathisa ukubethelwa kunye nokugoba ukugoba kwekhonkrithi, ukuphucula ukunyaniseka kwe-shotcrete, kunye nokunciphisa umngcipheko wokudubula.
