Ua ntej koj pib txhim kho cov laj kab ncej, koj yuav tsum npaj cov khoom tsim nyog thiab cov cuab yeej: seem, vaj laum, qib tsev, qib hydraulic, twine, cov khoom siv vov tsev, cement, xuab zeb, dej, pob zeb thiab lub thawv rau nplawm cov tshuaj.
Pib
Kev ua laj kab laj kab pib nrog kev kos npe tawm ntawm qhov chaw rau qhov drilling qhov hauv av uas siv lub vaj laum (yog tias koj muaj roj laum, qhov no yuav ua rau txoj haujlwm yooj yim heev). Txhawm rau ua qhov no, koj yuav tsum txiav txim siab qhov chaw ntawm thawj tus ncej. Nyob ntawd koj yuav tsum tau tsav lub peg ntoo thiab ncab lub twine mus rau qhov chaw ntawm tus ncej kawg. Yog li nws hloov tawm lub cim ntawm tag nrho lub laj kab. Thaum drilling, koj yuav tsum tau ua raws li txoj kab kom lub laj kab sib tw. Tom ntej no, koj yuav tsum tau kos npe rau qhov chaw uas lub concreting ntawm tus ncej nyob rau hauv lub laj kab yuav ua. Nruab nrab ntawm lawv koj yuav tsum tau ua qhov sib txawv, nyob ntawm seb cov khoom siv. Cov ncej rau cov saw txuas mesh yog ntsia ntawm qhov deb ntawm 3 m, rau lub laj kab ntoo lossis laj kab corrugated - 2.5 m. Yog tias koj ua qhov kev ncua deb ntawm lawv ntau tshaj 3 m, qhov no tuaj yeem ua rau lag sagging.
Drilling qhov thiab concreting laj kab ncej
Txhawm rau kom paub qhov tob npaum li cas rau kev xyaum, ib lub cim tau ua rau ntawm qhov auger ntawm qhov xyaum kom qhov deb ntawm 100-110 cm ntawm hauv av. Koj yuav tsum tuav lub laum vertically kom lub qhov dej txawm thiab tsis mus rau sab. Tsis tas li ntawd, thaum lawv drilled rau lub cim, txhawm rau tiv thaiv kev sib cuag ntawm kev daws nrog hauv av, ib daim ntawm cov khoom siv vov tsev dov rau hauv ib lub yob yog muab tso rau hauv lub qhov. Cia peb mus rau lub installation. Nyob rau ntawm ib tug ncej los ntawm sab saum toj, ib tug deb ntawm 150 cm yog cim thiab qis rau lub cim no. Yog tias tsim nyog, lub qhov yuav tsum tau muab sib sib zog nqus los yog nchuav kom qhov kev ncua deb. Tom qab ntawd tawg cib los yog gravel yog poured rau ntawd thiab rammed nrog crowbar. Qhov tseem ceeb tshaj plaws yog tsis txhob sau tag nrho thiab tawm ntawm qhov deb li ntawm 15-20 cm mus rau sab saum toj rau cov cement mortar. Thawj theem ntawm concreting lub laj kab ncej yog ua tiav. Tus ncej kawg yuav tsum tau teem raws li thawj zaug, rau qhov no lawv siv qib hydraulic.
Kev tsim laj kab ncej: qhov zoo thiab qhov tsis zoo
Muaj kev xav tias cov ncej pob zeb "sab" tawm hauv av dhau sijhawm. Qhov no tuaj yeem tshwm sim tsuas yog tias lawv tau ua tiav rau qhov tob ntawm tsawg dua ib 'meter'. Tab sis yog tias lawv khawb tob, tsis muaj dab tsi tshwm sim rau lawv. Ib qho txiaj ntsig tseem ceeb yog cov ncej pob zeb tsis rot hauv av, tsis zoo li cov uas tau tsav mus rau hauv av thiab tsis muaj kev tiv thaiv los ntawm ib txheej ntawm pob zeb. Txawm tias ib tsob ntoo zoo primed thiab pleev xim rau hauv av tsis tiv thaiv kom lwj. Yog hais tias tus ncej tsis concreted, tab sis hammered, lub laj kabnws yuav tig tawm "taug kev", vim tsis muaj txoj hauv kev los teeb tsa raws li qib. Yog hais tias koj theem ib tug clogged ncej, nws tsuas yog loosen, thiab ces koj yuav tsum tau xav txog kev ntseeg tau ntawm xws li ib tug tsim. Mechanized txoj kev yog zoo dua nyob rau hauv cov nqe lus ntawm kev ua hauj lwm, vim hais tias xws li concreting ntawm laj kab ncej, tus nqi ntawm uas tam sim ntawd yuav nce, ua rau lawv muaj zog thiab ntau txawm. Nws yog tsim nyog xav tias nws yog qhov zoo dua los ua txhua yam tam sim ntawd thiab tsis txhob txhawj txog nws ntau xyoo. Tsis tas li ntawd, los ntawm kev zoo nkauj, lub pob zeb pob zeb yog qhov zoo dua, vim tias tus tsav yuav deformed los ntawm saum toj no.
