Lub hauv paus, raws li txhua tus paub, yog qhov chaw hauv av ntawm lub tsev, nqa lub nra ntawm tag nrho nws cov qauv. Nyob rau hauv kev tsim kho ntawm cov tsev ntiag tug, ob peb hom ntawm lub hauv paus yog siv. Nws tuaj yeem yog columnar, daim kab xev, slab lossis pawg version.
Qhov txaus siab tshaj plaws feem ntau yog lub hauv paus sawb. Hom no yog qhov txawv los ntawm kev pom kev sib xyaw ua ke ntawm kev ntseeg siab, yooj yim ntawm kev tsim kho thiab tus nqi qis. Xws li lub hauv paus tuaj yeem siv rau yuav luag txhua hom av, tshwj tsis yog ntub heev thiab raug txav mus los.
Nws yuav tsum tau hais tias kev teeb tsa ntawm lub hauv paus sawb yog txheej txheem yooj yim. Qhov no yog ib tug nruam sawb ntawm cib, pob zeb los yog pob zeb, hla hauv qab lub tsev raws nws tag nrho perimeter. Ib qho prefabricated strip foundation ua los ntawm prefabricated blocks kuj siv.
Lub hauv paus cib yuav tsis pheej yig. Lub hauv paus ntawm cov blocks tiav yog npaj sai heev, tab sis qhov no yog qhov kev xaiv kim kim. Yog li ntawd, kev tsim kho ntawm ib qho monolithic feem ntau yog qhov kev daws teeb meem zoo tshaj plaws.
Ua ntej ua kev tshawb fawb geodetic. Raws li kev tshawb fawbtxiav txim ib co nta ntawm kev tsim kho technology, qhov tob ntawm lub hauv paus thiab lwm yam tsis.
Cov cuab yeej ntawm daim kab xev monolithic lub hauv paus tseem suav nrog kev npaj ua ntej ntawm qhov chaw thiab ua tib zoo cim. Kos npe yog nqa tawm siv pegs thiab twine. Pegs tau tsav mus rau txhua qhov chaw ntawm lub tsev yav tom ntej, ces twine yog rub ntawm lawv. Txhua lub ces kaum yuav tsum ncaj ncaj, thiab cov sab nraud yuav tsum yog tib yam thiab ntev. Kos ob sab hauv thiab sab nraud ntawm lub neej yav tom ntej pob zeb daim kab xev.
Pib lub hauv paus sawb los ntawm khawb lub hauv paus pit.
Qhov tob ntawm nws yuav nyob ntawm ntau yam. Feem ntau nws yog hais txog 50-70 cm, hauv qab yog leveled thiab ib lub hauv ncoo ntawm xuab zeb yog pw rau ntawm nws. Lub thickness ntawm cov xuab zeb cushion yuav tsum yog 12-20 cm. Tom qab ntawd, lub formwork yog mounted. Ntoo shields thiab spacers yog siv rau nws.
Ib txhij nrog lub formwork, kev txhim kho yog ntsia. Feem ntau cov tuav yog mounted nyob rau hauv ob kab thiab fastened nrog kab rov tav tuav. Nws yog qhov zoo tshaj plaws los siv tsis yog welded reinforcement, tab sis khi cov rods nrog ib tug tshwj xeeb hlau. Kev teeb tsa ntawm lub hauv paus sawb nrog cov kev txhawb nqa zoo li no yuav txo tau qhov tshwm sim ntawm nws cov corrosion, thiab, yog li ntawd, ua rau nws cov kev pab cuam lub neej.
Qhob yog nchuav me me, txog 15 cm txhua txheej. Qee lub sij hawm cov cuab yeej ntawm sawb foundations suav nrog qhov sib ntxiv ntawm cov pob zeb rubble rau pob zeb. Hauv qhov no, cov khaubncaws sab nraud povtseg yog stacked alternately. Txheej ua ntejpob zeb, ces pob zeb, ces lwm txheej ntawm pob zeb.
Ua kom tiav lub hauv paus sawb nrog kev ua haujlwm tsis muaj dej. Tom qab daim kab xev pob zeb tau sawv rau ib lub lim tiam thiab ib nrab, cov formwork tuaj yeem raug tshem tawm. Raws li ib tug waterproofing khoom, bituminous mastic thiab ru tsev ntaub yog siv. Sab nrauv phab ntsa ntawm daim kab xev yog them nrog mastic thiab ruberoid yog glued rau nws. Ua tib yam rau saum lub hauv paus. Tom qab ntawd koj yuav tsum sau qhov khoob ntawm phab ntsa ntawm daim kab xev thiab lub qhov. Sprinkle lawv nrog xuab zeb, nyob rau hauv me me txheej, uas yog rammed nrog dej. Lub hauv paus npaj txhij.
