Ntawm no yog ib qho kev piav qhia ntawm yuav ua li cas lub tshuab txhaj tshuaj ntub dej ua haujlwm thiab nws daim ntawv thov hauv kev tiv thaiv txoj kab nqes:
Yuav ua li cas ntub Shotcrete Machine Ua Haujlwm:
Kev sib xyaw:Hauv cov txheej txheem kev txhaj tshuaj ntub dej, cov pob zeb ua ntej sib xyaw (xws li dej) tau muab rau hauv lub tshuab.
Pump Mechanism:Cov dej sib tov yog pumped los ntawm ib lub hose mus rau lub nozzle.
Daim ntawv thov nozzle:Ntawm lub nozzle, compressed cua yog qhia kom ceev qhov sib tov, txau rau saum npoo.
Adhesion thiab Compaction:Qhov siab tshaj plaws ua kom zoo compaction thiab adhesion rau txoj kab nqes saum npoo, txawm nyob rau qhov chaw tsis sib xws lossis tsis sib xws.
Qhov zoo ntawm kev siv Wet Shotcrete rau kev tiv thaiv kab nqes:
Kev siv tau zoo:Cov txheej txheem ntub dej tso cai rau daim ntawv thov sai dua piv rau qhuav shotcrete.
Tsawg plua plav:Cov tshuaj tua kab ntub dej ua kom muaj plua plav tsawg, ua rau nws muaj kev nyab xeeb rau cov neeg ua haujlwm thiab ib puag ncig.
Zoo ib yam:Lub pre-mixed pob zeb ua kom cov khoom sib xws.
High Bond Strength:Nws adheres zoo rau ntau qhov chaw, nrog rau pob zeb thiab av.
Reinforcement Integration:Nws tuaj yeem yooj yim suav nrog kev txhawb nqa zoo li steel mesh lossis fibers rau ntxiv dag zog.
Cov kauj ruam hauv kev tiv thaiv nqes hav siv Wet Shotcrete:
Kev npaj nto:
Ntxuav txoj kab nqes kom tshem tawm cov khib nyiab, cov nroj tsuag, lossis cov khoom tsis ruaj khov.
Txhim kho cov kav dej yog tsim nyog los tiv thaiv cov dej hauv qab ntawm txoj kab nqes.
Reinforcement Placement:
Muab cov hlau mesh, steel tuav, lossis lwm yam kev txhawb nqa raws li xav tau los txhim kho cov qauv kev ruaj ntseg.
Daim ntawv thov Shotcrete:
Siv cov tshuaj tua kab ntub dej rau hauv cov khaubncaws sab nraud povtseg, kom ntseeg tau tias cov tuab tuab thiab kev tiv thaiv zoo ntawm txoj kab nqes.
Kho lub nozzle lub kaum sab xis thiab kev ncua deb kom paub meej tias qhov adhesion thiab compaction.
Kho:
Khaws cov shotcrete moist rau kev kho kom zoo, kom ntseeg tau lub sijhawm ntev thiab lub zog.
Thaum kawg Touches:
Smoothen los yog kho qhov chaw raws li qhov xav tau rau kev zoo nkauj lossis kev ua haujlwm zoo.
Ntxiv cov txheej tiv thaiv lossis cov nroj tsuag (hydroseeding) rau kev tiv thaiv kev yaig ntxiv, yog tias xav tau.
Daim ntawv thov nyob rau hauv Slope Protection:
Stabilization ntawm steep embankments.
Erosion tswj nyob rau hauv toj siab.
Kev tiv thaiv Rockfall nyob rau thaj tsam roob.
Kev txhawb nqa phab ntsa.
Cov tshuab ntxhua khaub ncaws ntub dej muaj ntau yam thiab siv tau zoo hauv cov phiaj xwm kev tiv thaiv kab nqes, muab cov kev daws teeb meem ruaj khov thiab cov nqi tsim nyog los xyuas kom lub sijhawm ntev thiab kev nyab xeeb.
