Yuav ua li cas lub diaphragm phab ntsa tsim

Diaphragm phab ntsa yog ib lub diaphragm phab ntsa nrog anti-seepage (dej) tuav thiab load-bearing functions, tsim los ntawm excavating ib nqaim thiab sib sib zog nqus trench underground nrog kev pab los ntawm excavation machinery thiab av nkos tiv thaiv, thiab tsim cov ntaub ntawv tsim nyog xws li cov pob zeb muaj zog nyob rau hauv lub trench. .

Nws muaj kev koom tes hauv kev lag luam xws li kev tsim kho, kev tsim vaj tsev hauv nroog, thiab kev loj, feem ntau yog tsim rau kev sib sib zog nqus lub hauv paus pit enclosure, cov tsev uas twb muaj lawm, kev tiv thaiv ib puag ncig, thiab cov phiaj xwm cuam tshuam nrog kev sib cais.

Excavation ntawm kev taw qhia ditch → kev tsim kho ntawm phau ntawv qhia phab ntsa → excavation ntawm trench → tshem tawm cov silt thiab residue nyob rau hauv qab ntawm lub trench → lifting ntawm cov yeeb nkab sib koom → lifting ntawm steel tawb → txo cov conduit → pouring ntawm pob zeb → extraction ntawm cov yeeb nkab sib txuas

① Excavate trench thiab tsim cov phab ntsa

Phau ntawv phab ntsa: Cov qauv tseem ceeb uas tswj xyuas qhov tseeb ntawm kev khawb, thiab cov qauv qhia phab ntsa yuav tsum tau ua rau ntawm lub hauv paus ruaj khov.

Kev ua haujlwm ntawm phab ntsa qhia: khaws cov av, ntsuas kev ua haujlwm, kev thauj khoom thauj, av nkos, thiab lwm yam haujlwm.

② Excavate trench

Qhov ntev yuav tsum nyob nruab nrab ntawm 4 thiab 6 meters.

Tshawb xyuas thiab tswj cov ntsuas kev ua haujlwm tseem ceeb xws li tus txheeb ze ntom ntom, viscosity, xuab zeb cov ntsiab lus, thiab pH tus nqi ntawm cov av nkos.

③ Cov yeeb nkab txuas txuas

Lub groove seem pob qij txha ntawm cov phab ntsa diaphragm yuav tsum raug xaiv raws li cov hauv qab no:

1) Cov pob qij txha yooj yooj yim xws li lub voj voog kaw cov yeeb nkab sib txuas, cov yeeb nkab corrugated, cov pob qij txha zoo li cov pob qij txha, I-beam pob qij txha, los yog cov pob qij txha precast yuav tsum tau siv rau cov phab ntsa diaphragm;

2) Thaum lub diaphragm phab ntsa yog siv los ua lub ntsiab sab nrauv phab ntsa ntawm cov qauv hauv av thiab xav tau los ua ib lub phab ntsa tag nrho, cov pob qij txha yuav tsum tau siv;

Cov pob qij txha tuaj yeem ua tau siv perforated steel phaj pob qij txha nyob rau hauv ib tug ncaj los yog ntoo khaub lig zoo, steel bar socket pob qij txha, thiab lwm yam.

Qhov zoo ntawm diaphragm phab ntsa:

1) High rigidity, loj excavation qhov tob, haum rau tag nrho cov strata;

2) Lub zog muaj zog, kev hloov me me, dej tsis kam, thiab tuaj yeem ua ib feem ntawm cov qauv tseem ceeb;

3) tuaj yeem siv tau ze ze rau cov tsev thiab cov qauv, nrog rau kev cuam tshuam ib puag ncig tsawg.
