Indlela yofakelo

5.1 Ukusika indawo yokubeka:

Amanyathelo

Umfanekiso

1 Iimpawu zesilumkiso sokwakha kufuneka zibekwe phambi kwendawo yokwakha.2)Zoba umgca: sebenzisa iteyiphu, ipensile yesileyiti kunye nomthombo we-inki ukuzoba kunye nokumakisha indawo apho inzwa ibekwe khona, qinisekisa nokuba iintambo zinde ngokwaneleyo ukuba zidibanise ecaleni kwendlela. ikhabhinethi.3 Ukusika i-slot: sebenzisa i-cutter ukuvula i-groove yesikwere endleleni kunye nomgca wokumakisha.Ubungakanani obunqamlekileyo be-groove kufuneka ilawulwe ngokuchanekileyo phakathi koluhlu oluchaziweyo (jonga umzobo kwicala lasekunene).Ngokobude be-sensor, nzulu ubunzulu be-groove ekupheleni ukuya kwi-50mm (ukulungelelanisa kwintloko yokuphuma kwenzwa kunye nokuphela).

4) Ukophulwa kwendlela:usesa ihamile ukuya kwigroove kwaye uchebe emazantsi omqolo.I-bottom of the groove kufuneka inqunywe ngokucokisekileyo ngokunokwenzeka.

Ngokomzobo: umfanekiso ochanekileyo kunye nemizobo yokwakha esisiseko efanelekileyo.

Izixhobo eziphambili: umatshini wokusika i-pavement, isando sempembelelo, i-hoe, i-drill.

Phawula:

Lawula ubunzulu obutyumzayo bomjelo onyukayo.Ukuba ayinzulu kakhulu, inzwa kunye nesibiyeli azinakuhlala phantsi.Ukuba inzulu kakhulu, inani le-groutiya kuba nkulu.

igroutiya kuba nkulu.

5.2 Amanyathelo acocekileyo nawomileyo

I-1, Ukuqinisekisa ukuba izinto zokubumba zinokudibaniswa kakuhle kunye nomgangatho wendlela emva kokuzaliswa, indawo yokufakela i-slot kufuneka ihlanjwe nge-high-pressure cleaner, kwaye umphezulu we-groove kufuneka uhlanjwe ngebrashi yensimbi, kwaye icompressor yomoya/ umpu womoya woxinzelelo oluphezulu okanye i blower isetyenziswa emva kokucoca ukomisa amanzi.

2, Emva kokuba i-debris icociwe, uthuthu oludadayo kwindawo yokwakha kufuneka lucocwe.Ukuba kukho amanzi aqokelelweyo okanye ukufuma okubonakalayo okubonakalayo, sebenzisa i-compressor yomoya (umpu womoya ophezulu) okanye i-blower ukuze uyomise.

I-3, Emva kokuba ukucoca kugqityiwe, i-tape yokutywina (ububanzi obungaphezu kwama-50mm) isetyenziswa
ukuya kumphezulu wendlela ejikeleze inotshi ukuthintela ungcoliseko kwi-grout.

5.3 Uvavanyo lofakelo lwangaphambili

I-1, i-Capacitance yokuvavanya: Sebenzisa i-digital multi-meter ukulinganisa i-capacitance epheleleyo ye-sensor kunye nekhebula eliqhotyoshelweyo.Ixabiso elilinganisiweyo kufuneka libe phakathi koluhlu oluchazwe yinzwa yobude obuhambelanayo kunye nedatha yedatha yekhebula.Uluhlu lomhloli ludla ngokusetwa kwi-20nF.I-probe ebomvu idibaniswe kwingundoqo yekhebula, kwaye i-black probe ixhunywe kwisikhuselo sangaphandle.Qaphela ukuba akufanele ubambe zombini iziphelo zoqhagamshelwano ngexesha elinye.

I-2, ukuchasana novavanyo: Ukulinganisa ukuchasana kweziphelo zombini zenzwa kunye ne-digital multi-meter.Umitha kufuneka usetelwe ku-20MΩ.Ngeli xesha, ukufundwa kwiwotshi kufuneka kudlule i-20MΩ, edla ngokuboniswa ngu "1".

5.4 Lungisa isibiyeli sokuxhoma

Amanyathelo

Umfanekiso

1) Khupha inzwa kwaye ujonge ukuba inzwa yoluvo ilungile.Qinisa isivamvo ukuze ugcine isivamvo sithe tye kwaye sicaba.2) Vula isibiyeli sokuxhoma kwibhokisi kwaye ufake isibiyeli ecaleni kwesivamvo malunga nezithuba ze-15cm.3) Beka isibiyeli sokuxhoma kunye nesivamvo.

kwindawo yokusika.Umphezulu wazo zonke izibiyeli umalunga ne-10mm ukusuka kumphezulu wendlela.

4) Goba isiphelo senzwa phantsi kwe-40 °, thoba umdibaniso phantsi kwe-20 °, uze ugobe i-20 ° ukuya phezulu ukuya kwinqanaba.

5.5 Hlanganisa i-grout

Qaphela: Nceda ufunde imiyalelo ye-grout ngononophelo ngaphambi kokuxuba.
I-1) Vula i-potting grout, ngokwesantya sokuzalisa kunye nomthamo ofunekayo, unokwenziwa ngamanani amancinci kodwa amaxesha ambalwa ukuphepha inkunkuma.
2) Lungiselela ubungakanani obufanelekileyo be-potting grout ngokomlinganiselo ochaziweyo, kwaye ugxobhoze ngokulinganayo ngehamile yombane (malunga nemizuzu emi-2).
3) Emva kolungiselelo, nceda usebenzise ngaphakathi kwemizuzu engama-30 ukunqanda ukuqina kwibhakethi.

5.6Amanyathelo okuzalisa igrout yokuqala

1) Galela i-grout ngokulinganayo kubude bomsele.
I-2) Xa ugcwalisa, i-port ye-drainage ingenziwa ngesandla ukuze iququzelele ukulawulwa kwesantya kunye nolwalathiso ngexesha lokuthulula.Ukugcina ixesha kunye namandla omzimba, inokugalelwa ngezikhongozeli zomthamo omncinci, olungele abantu abaninzi ukuba basebenze ngaxeshanye.
3) Ukuzaliswa kokuqala kufuneka kube neendawo zokubeka ezigcweleyo, kwaye wenze umphezulu wegrout ube phezulu kancinane kunepavumente.
4) Gcina ixesha kangangoko kunokwenzeka, ngaphandle koko i-grout iya kuqinisa (le mveliso inexesha eliqhelekileyo lokunyanga le-1 ukuya kwiiyure ze-2).

5.7Amanyathelo okuzalisa igrout yesibini

Emva kokuba i-grouting yokuqala iphilisiwe, jonga umphezulu we-grout.Ukuba umgangatho uphantsi kunomgangatho wendlela okanye umphezulu we-dedent, xuba i-grout (jonga inyathelo lesi-5.5) kwaye wenze ukuzaliswa kwesibini.
Ukuzaliswa kwesibini kufuneka kuqinisekise ukuba ubuso be-grout buncinci ngaphezu kwendlela.

5.8Ukusila phezu komhlaba

Emva kokufakela inyathelo le-5.7 ligqityiwe isiqingatha seyure, kwaye i-grout iqala ukuqina, ikrazule iiteyipu kumacala eslots.
Emva kokufakela inyathelo le-5.7 ligqityiwe iyure eli-1, kwaye i-grout iqiniswe ngokupheleleyo, igaye
igrout nge-engile grinder ukuyenza igungxulwe nomphezulu wendlela.

5.9 Ukucocwa kwendawo kunye novavanyo lwasemva kokufakwa

1) Coca iintsalela zegrout kunye nolunye ubutyobo.
2) Uvavanyo emva kofakelo:

(1) Uvavanyo lovavanyo: sebenzisa i-digital meter meter ukulinganisa i-capacitance epheleleyo ye-sensor kunye nekhebula eliqhotyoshelweyo.Ixabiso elilinganisiweyo kufuneka libe phakathi koluhlu oluchazwe yinzwa yobude obuhambelanayo kunye nedatha yedatha yekhebula.Uluhlu lomhloli ludla ngokusetwa kwi-20nF.I-probe ebomvu idibaniswe kwingundoqo yekhebula, kwaye i-black probe ixhunywe kwisikhuselo sangaphandle.Qaphela ukuba ungabambi iziphelo zoqhagamshelwano ezimbini ngexesha elinye.

(2) Ukumelana novavanyo: sebenzisa i-digital meter ezininzi ukulinganisa ukuchasana kwenzwa.Umitha kufuneka usetelwe ku-20MΩ.Ngeli xesha, ukufundwa kwiwotshi kufuneka kudlule i-20MΩ, edla ngokuboniswa ngu "1".

(3) Uvavanyo lwangaphambili lomthwalo: emva kokuba indawo yokufakela icociwe, qhagamshela i-sensor output kwi-oscilloscope.Ukusetwa okuqhelekileyo kwe-oscilloscope yile: Voltage 200mV/div, Ixesha 50ms/div.Ngophawu oluhle, i-voltage ye-trigger isetelwe malunga ne-50mV.Ubume obuqhelekileyo belori kunye nemoto iqokelelwa njengovavanyo lwamaza ovavanyo lwangaphambi komthwalo, kwaye ke ifom yovavanyo lwamaza iyagcinwa kwaye ikhutshelwe ukushicilelwa, kwaye igcinwe ngokusisigxina.Ukukhutshwa kwenzwa kuxhomekeke kwindlela yokunyuka, ubude benzwa, ubude bekhebula kunye nezinto zokubumba ezisetyenzisiweyo.Ukuba uvavanyo lokulayishwa kwangaphambili luqhelekileyo, ukufakwa kugqityiwe.

I-3) Ukukhutshwa kwe-Traffic: amanqaku: I-Traffic inokukhululwa kuphela xa i-potting material iphiliswe ngokupheleleyo (malunga ne-2-3 iiyure emva kokuzaliswa kokugqibela).Ukuba i-traffic ikhutshwe xa i-potting material ingapheliswanga ngokupheleleyo, iya kulimaza ukufakela kwaye ibangele ukuba inzwa ingaphumeleli kwangaphambi kwexesha.
