Me nyuam yaus rau lub plhis ntawm tus menyuam

Lub tsev teb yog ib qho tseem ceeb thiab tseem ceeb cwj pwm ntawm cov infield. Ua tsaug rau cov uas nws kim heev ntau yam ntawm cov ntaub ntawv thiab cov cuab yeej tau creation ntawm ib tug neeg sab nraud siv tsis tau cov kev pab los ntawm cov tub txawg. Nws tag nrho cov pib nrog rau lub hauv paus.

Yuav ua li cas yuav tsum xyuam xim rau cov pib ntawm kev tsim kho

Me nyuam yaus rau lub plhis yuav xaiv raws li tus muaj zog ntawm cov av thiab lub hom. Los ntawm cov kws muaj txuj tsom xam ntawm cov av nws yog tau cov kev xaiv ntawm cov pom variant bases.

Av hom:

• zeb av zoo ua qoob;
• av zoo ua qoob;
• gravel;
• av nplaum;
• pob zeb.

Dua li ntawm qhov yooj yim thiab yooj yim ntawm kev tsim kho, rau nws siv yog pom tias yuav ua tau lub feem ntau tsim nyog hom mob rocky av nyob rau hauv ib tug tuab array tsis muaj voids thiab tej kab nrib pleb. Nws yog yus muaj los ntawm ib tug tsis muaj xuab zeb, cia kom khov nyob rau hauv lub txias rau lub caij, subsidence, muaj peev xwm ua lub hauv paus thiab ib ncig ntawm lub qauv txaus stability.

tshiab technologies

Los ntawm txoj kev loj hlob ntawm lub cheeb tsam favorites thaj av xws li, nws puas yuav tau siv high-zoo siv nyob rau hauv lub gravel, av nplaum xau, raws li zoo raws li nyob rau zeb av zoo ua qoob thiab av zoo ua qoob. Yog li ntawd nws yuav tsis tshua muaj ib qho tseem ceeb subsidence ntawm cov av, nws tseem ceeb compression, raws li zoo raws li lub xub ntiag ntawm quicksands thiab te heaving.

av o yuav tshwm sim ob leeg rau lub sab ntawm tus qauv, thiab nyob rau hauv nws. Me nyuam yaus rau plhis yuav muaj kev tiv thaiv los ntawm qhov no nyob rau hauv lub nram qab no:

• tshem heaving xau nyob rau hauv kev tsim kho ntawm qhov chaw thiab nws hloov nrog gravel thiab ntxhib xuab zeb;
• tsim ib tug monolithic lub hauv paus;
• waterproofing thiab thermal rwb thaiv tsev ntawm lub hauv paus los ntawm tag nrho cov sab;
• allergic ntawm lub hauv paus hauv qab no tus khov.

rau pouring cov tshuaj

Zoo cov me nyuam yaus rau plhis kom cia siab rau thiab durability ntawm vaj tse. Kev mloog yuav tsum tau muab rau lub Cheebtsam ntawm cov tshuaj. Txaus cov yam ntxwv sib txawv standard Portland MAAs, tab sis nws yuav tsum muaj qhov tseeb lawm hnub. Desirably tau rubble nplua, vim rau qhov cov txo cov ntaub ntawv uas noj, cov tshuaj yuav denser thaum lub sij hawm pw thiab ntau monolithic thaum lub sij hawm solidification. Nws yog ib qho tseem ceeb rau hauv lub qhaj ntawv ntawm impurities thiab khib nyiab nyob rau hauv tag nrho cov Cheebtsam, xws li cov dej. Nyob rau hauv thiaj li yuav tau ib tug tov ntawm mixed MAAs, xuab zeb thiab gravel nyob rau hauv lub kws ratio, ces nchuav portionwise nrog dej rau ib tug uniform khob noom cookie.

Nyob rau uas txhim tsa lub tsev

Substrate hom yog xaiv nyob ntawm seb cov nyiaj txiag muaj peev xwm, kuj mus rau lub phiv los (khov, underground dej) thiab tam sim no rau hauv av feem.

Sawb me nyuam yaus rau plhis muaj ntau ntau yam thiab check. Lawv ntaus ntawv pib nrog cov kev khawb ntawm cov trench. Ua ntej no seem yog cim thiab teem tej ceg txheem ntseeg uas muaj twine nyob ib ncig ntawm lub perimeter ntawm lub neej yav tom ntej vaj tse, ncav us txog nruab nrab ntawm lawv.

Lub hauv paus yuav tau ntxiv zog thiab solidity thaum nws sau rau ib hnub thiab kom huv si compacted. Nws yog ib nqi nco ntsoov hais tias rau cov hardening ntawm qhob uas yuav tsum tau rau ob peb hnub, thiab thaum lub sij hawm lub tshav kub, kom tsis txhob ntes, nws tsis tseg hliv dej rau.

Av nplaum av nws yog ntshaw kom nphoo gravel. Tob instillation kev pab txhawb nqa tug ncej yog xam raws li mus rau theem ntawm kev soj ntsuam xyuas rau cov nqi no yuav tsum muab ntxiv lwm 15 cm. Mounted them nyiaj yug ntawm av ci los yog qhob ntawm cov pob qij txha ntawm cov phab ntsa thiab lub ces kaum ntawm lub hauv paus. Lub hauv qab ntawm txhua lub caij so yog lawm ua tus sau nrog xuab zeb thiab gravel, ua raws li compacted. Yuav kom nce lub dag lub zog nyob rau hauv qhov chaw yog ib tug steel pas nrig.

Yuav kom tiv thaiv subsidence ntawm cov qauv mus rau hauv qab ntawm stacked tam-pob zeb ua lub hauv paus. Masonry tug ncej yuav siv sij hawm rau hauv lub tshuav qhov chaw nyob rau hauv lub caij so.

Cov yuav txhawb tau txhua rau lub teeb ntoo siv yuav ua los ntawm zoo xws li cov ntaub ntawv. Siv rau waterproofing impregnation ntawm tshwj xeeb mastics los yog kub. Vim rau qhov no, ib tug tsev teb puv greener thiab nyiaj.

Lub hauv paus rau ib lub tsev teb ntawm lub blocks

Penoblok yog khaub-ncaws nyias thiab check cov ntaub ntawv uas nrog tsim nyog tus nqi. Teem caij yog ib qho yooj yim txaus txawm rau cov neeg uas tsis koom nyob rau hauv xws ua hauj lwm. Thov puag thiab phab ntsa, uas txo lub zuag qhia tag nrho load rau hauv av. Nws pib kho ntawm ib tug trenching los yog excavation, Yog hais tias koj yuav tsum tau tsim ib tug hauv qab daus.

Siv qhov tob xam xa mus rau saum toj no, lub dav nyob rau hauv cov ntaub ntawv no yog qhov thaiv thickness thiab ib qho ntxiv 20 cm. Tom qab ntawm lub qhov taub (trench) yog sau lub tog hauv ncoo ntawm cov xuab zeb thiab gravel, yog ces ntsia formwork nrog lub reinforcing ncej. Qhob yog poured rau sab saum toj, thiab ib tug txheej yuav tsum tau txog 20 cm. Cov ua npuas ncauj blocks Mounting tau tsuas yog tom qab ua tiav solidification.

Lub hauv paus rau ib lub tsev teb ntawm npaus blocks txawv yooj yim ntawm installation, pheej yig tus nqi, ua hauj acid av thiab tus ntawm cia kom khov, lub neej ntev thiab me ntsis lub sij hawm-siv rau nws kho.

Qhov chaw ua npuas ncauj blocks pib nrog cov ces kaum ntsiab lus. Filling lwm vuam yog nqa tawm nrog rau qhov sib ntxiv ntawm txhais tau tias kev tiv thaiv tiv thaiv dej. Base nyob rau txheej sab enveloped xaiv waterproofing khoom, ces tus trench yog khawb.

Asbestos kav nyob puag vaj tse

Rau cov me nyuam yaus tsim plhis ntawm cov kav dej asbestos- yam uas lawv installation nyob rau hauv lub qhov dej drilled thiab pouring ntawm qhob sib tov. Siv reinforcing tawb kom muaj zog cia siab rau thiab durability. Tab sis, zoo li lwm yam tsim, nws muaj nws qhov zoo thiab qhov tsis zoo.

Ntawm cov drawbacks muaj nqis ntsoov teev cov fragility ntawm kev siv. Yog lub siab tshaj plaws lub sij hawm ntawm lub lag luam ntawm 70 xyoo, xav tias qhov tseeb hais tias ua kev reinforced hauv paus yog tau mus sawv ntsug rau ib tug ob peb puas xyoo, cov me nyuam yaus ntawm cov pob zeb thiab cib kuj txawv los ntawm ib tug ntev kev pab cuam lub neej.

Lub columnar qauv ntawm cov kav dej yuav siv tsis tau rau mos xau, av muaj dej thiab struts nrog loj nyem sib txawv.

Nyob rau hauv cov kev phem ntawm no, qhov no hom ntawm lub hauv paus muaj ntau yam zoo:

• Rau curing yuav siv sij hawm txog ib lub lim tiam, ces koj yuav pib ntxiv ua hauj lwm.
• Tsis xav mus yuav lumber los tsim kom tau formwork.
• Tsis tshua muaj nqi. Asbestos-xis mas kav hom yog cheaper npaum li pob zeb blocks los ua vaj tse pawg.
• Tsis xav mus khawb ib trench, dlhos cov hauv qab thiab sau cov xuab zeb thiab gravel sib tov, raws li yuav tsum tau los ntawm ib co hom bases.
• Rau lub installation tsis yuav tsum tau nqa cov khoom thiab cov kws muaj txuj pab.
