Kusamalira ndi kusamalira ma bunker a malo ochitira gofu nthawi zonse

Malo osungiramo zinthu (bunkers) amagwira ntchito yofunika kwambiri pakugwiritsa ntchito malo ochitira gofu ndipo sangasinthidwe. Kusamalira udzu wa bunker wa malo ochitira gofu kumakhudza mwachindunji momwe malo onse ochitira gofu amakhalira, ndipo kusamalira mchenga pamwamba pa bunker kumakhudza mwachindunji mtundu wa mpira wa gofu kwa alendo. Malo osungiramo zinthu (sandbed holders) okonzedwa bwino adzapatsa alendo chisangalalo chosewera gofu komanso mawonekedwe achilengedwe. Pansipa, ndafotokoza mwachidule njira zina zotetezera zokhudzana ndi zofunikira pakukonzekera malo ochitira gofu tsiku ndi tsiku ndipo ndagawana ndi akatswiri ndi anzanga.

一. Ntchito ya sandpit
Bunker imatanthauza malo olepheretsa omwe amapangidwa pochotsa udzu ndi dothi, ndikulisintha ndi mchenga kapena zinthu zofanana ndi mchenga, ndikumaliza kukhala ngati khoma.
Ntchito za bunker ndi izi: ① Chimakhala ngati cholepheretsa kuwonjezera vuto la kusewera gofu; ② Patsani bwaloli mawonekedwe amitundu yosiyanasiyana komanso osiyanasiyana; ③ Onetsani komwe mpira ukupita.

二. Zofunikira zonse za maenje amchenga
1. Kutalika kwa m'mphepete mwa bunker: Kutalika kwa m'mphepete mwa bunker nthawi zambiri kumakhala 4-125px. Malo odulidwa ayenera kukhala oyera ndipo mizere iyenera kukhala yosalala.
2. Kukhuthala kwa mchenga wa bunker: Kukhuthala kwa mchenga wa bunker nthawi zambiri kumakhala pafupifupi 375px
3. Kuyika kwama reki a mchengaMa reki a mchenga ayenera kuyikidwa pafupi ndi m'mphepete mwa bunker, ndi mano a reki akuloza pansi ndipo mutu wa reki ukuloza ku wobiriwira. Ayenera kuyikidwa pamalo osavuta kufikako ndikugawidwa mofanana. Chiwerengero cha ma reki a mchenga chiyenera kutengera kukula kwa bunker.
4. Zofunikira pa mchenga wa bunker: Kusankha bwino mchenga kudzakhudza ubwino wa chithunzicho. Mtundu wa mchenga uyenera kukhala wofanana. Kukula kwa mchenga makamaka ndi 0.25 ~ 0.50mm, pafupifupi 60% - 70%, ndi bwino kusefa mchenga. Mchenga wopyapyala kwambiri ukhoza kukhudza madzi otuluka. Kapangidwe ka mchenga kuyenera kukhala kozungulira osati kozungulira, chifukwa mchenga wozungulira ungapangitse kuti pamwamba pake pakhale polimba, pomwe mchenga wozungulira ndi woterera komanso woterera. Umatha kuuluka mosavuta ndipo umatha kumira alendo akaima.
5. Zofunikira pa pamwamba pa mchenga: Pamwamba pa mchenga payenera kukhala posalala malinga ndi malo a bunker, popanda mafunde kapena ziphuphu. Mchenga uyenera kukhala wofanana komanso woyera, wopanda udzu kapena kudula udzu.

三. Malangizo osamalira udzu tsiku ndi tsiku pafupi ndi maenje amchenga
1. Kuthirira udzu pafupi ndi dzenje la mchenga
Malo odyetsera udzu omwe ali pafupi ndi bunker ali ndi malo otsetsereka akuluakulu ndipo ali ndi mphuno zambiri. N'zovuta kuthirira bwino mukamathirira. Ayenera kusakanikirana ndi kuthirira kowonjezera, ndipo malo odyetsera mphuno a bunker ayenera kubooledwa ndi manja ngati pakufunika kutero.
2. Kudula udzupambali pa dzenje la mchenga
Udzu womwe uli pafupi ndi bunker uyenera kusungidwa bwino komanso wowoneka bwino ndi bunker. Mphuno ya bunker iyenera kukhala yozungulira komanso yosalala, yopanda udzu kapena mawanga akuda. Kutalika kwa udzu pafupi ndi bunker nthawi zambiri kumakhala 3-125px. Pali malo otsetsereka m'mphepete mwa bunker, ndipo masamba a udzu amakhala opendekera pang'ono, kotero tsamba la makina odulira udzu liyenera kukhala lakuthwa podula, apo ayi udzuwo udzakhala ndi ubweya komanso woyera, koma muyeneranso kusamala kuti musadule udzu.
3. Kusamalira feteleza pa udzu pafupi ndi malo obzala mchenga
Tizilombo ndi matenda omwe ali pa udzu pafupi ndi bunker ndi osavuta kunyalanyaza. Udzu womwe uli pafupi ndi bunker uyeneranso kusamalidwa bwino. Makamaka, kupopera kuyenera kusamalidwa bwino. Ndi bwino kugwiritsa ntchito mfuti yopopera yosiyana ndikuyima mu bunker kuti mupopere. Mukayima pamwamba pa bunker, kupoperako sikukhala kofanana. Kuphatikiza apo, mankhwala nthawi zambiri amapakidwa mbali imodzi ya masamba a udzu, zomwe sizingakwaniritse zomwe mukufuna. Utsi wopopera kuchokera ku mfuti ya mankhwala uyenera kuyang'aniridwa mwachindunji pa udzu, kuti mankhwalawo aphimbe kwathunthu tsinde ndi masamba a udzu. Pazochitika zoopsa, ngakhale pansi pa tsinde payenera kuphimbidwa.
4. Kuchepetsa udzu ndi kuboola mabowo pafupi ndi dzenje la mchenga
Mphepete mwa bunker ndi yotsetsereka pang'ono ndipo zotsukira ndi zotulutsira mpweya sizingagwire ntchito. Kuti muchepetse udzu, mungagwiritse ntchito chotsukira mano chopangidwa molunjika komanso molunjika. Kuboola kungachitike pamanja ndi bolodi la misomali lopangidwa kunyumba, kapena ndi chobowola m'munda (chomwe ndi choopsa, choncho chonde samalani ndi chitetezo panthawi yogwira ntchito). Malo olowera ndi otulukira a makina otsukira mchenga m'mphepete mwa bunker ayenera kubooledwa nthawi zonse kuti apewe ndikuwongolera kuuma, pafupifupi kamodzi pamwezi panthawi yolima udzu, ndipo akhoza kusamalidwa ndikusamalidwa malinga ndi mikhalidwe inayake.
