Op-plek sagtegrondverbeteringsprojekte vertrou swaar op gestandaardiseerde werkvloei. Hierdie dokument sorteer die volledige konstruksievolgorde van vakuumvoorlading, vanaf voor-konstruksie voorbereiding tot voltooiingsaanvaarding. Dit dien as \u2019n praktiese verwysing vir tegniese personeel en konstruksiebestuurspersoneel.<\/p>\n\n\n\n

Algehele Konstruksievolgorde:<\/strong> <\/p>\n\n\n\n

Terreinhoogmaak en vlakmaak \u2192 Opmeting en uitsetting \u2192 Prefab vertikale dreininstallasie \u2192 Horisontale dreinnetwerk l\u00ea \u2192 Se\u00eblsisteem konstruksie \u2192 Toerustinginstallasie en inwerkingstelling \u2192 Vakuumpomp en drukstabilisering \u2192 Volgprosesse monitering \u2192 Ontlading en aanvaarding<\/p>\n\n\n\n

Stap 1: Terreinhoogmaak en vlakmaak<\/strong> <\/p>\n\n\n\n

Verwyder onkruid, slib en konstruksieafval van die terrein. Vlak die grond en elimineer uitsteekende en depressies. Voorkom dat skerp voorwerpe die se\u00eblmembrane deurboor en voorsien \u2019n plat basis vir daaropvolgende operasies.<\/p>\n\n\n\n

Stap 2: Opmeting en Uitsetting<\/strong>\u00a0<\/p>\n\n\n\n

Voer presiese uitleg uit volgens ontwerptekeninge. Merk installasiepunte van prefab vertikale dreine, roetes van dreinpype en grense van verbeteringsone. Stel duidelike merkers in om spasi\u00ebring en diepte te verseker volgens ontwerpspesifikasies.<\/p>\n\n\n\n

Stap 3: Prefab Vertikale Dreininstallasie<\/strong> <\/p>\n\n\n\n

Gebruik gespesialiseerde drein-invoermasjiene vir posisionering en installasie. Beheer streng die installasiediepte, vertikaliteit en spasi\u00ebring. Vermy dreinretensie, breuk en offset. Sny en vasmaak dreine na voltooiing om ononderbroke dreiningskanale te verseker.<\/p>\n\n\n\n

Stap 4: L\u00ea van Horisontale Dreinnetwerk<\/strong> <\/p>\n\n\n\n

L\u00ea fleksibele filterbuise en hoof-vertakkingspypnetwerke. Koppel vertikale dreine akkuraat aan takpype. Rangskik pype eweredig met redelike hellings, vry van knope en blokkades om \u2019n volledig verbonden dreiningsisteem te vorm.<\/p>\n\n\n\n

Stap 5: Se\u00eblsisteem Konstruksie<\/strong> <\/p>\n\n\n\n

L\u00ea basis-geoteksiel om die dreiningsisteem te beskerm, gevolg deur meerslae se\u00eblmembrane. Las membraneverbindinge stewig deur termiese fusie. Verberg membrane-rande in se\u00eblgleuwe en kompakteer vir \u2019n stywe sluiting om luglekkasies te elimineer.<\/p>\n\n\n\n

Stap 6: Toerustinginstallasie en Inwerkingstelling<\/strong> <\/p>\n\n\n\n

Installeer vakuumpompe, water-gas-skeiders en moniteringsinstrumente. Koppel pypestelsels en inspekteer kringe en se\u00eblprestasie deeglik. Voer geen-lading inwerkingstelling uit om normale toerustingwerking te verifieer.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Stap 7: Voortdurende Vakuumpomp en Drukstabilisering<\/strong> <\/p>\n\n\n\n

Begin formele vakuumpomp en verhoog geleidelik vakuumdruk. Handhaaf stabiele negatiewe druk bo 80\u202fkPa met deurlopende werking; vermy willekeurige afsluitings. Neem behoorlike ter plaatse beskermingsmaatre\u00ebls.<\/p>\n\n\n\n

Stap 8: Volgprosesse Monitering en Beheer<\/strong>\u00a0<\/p>\n\n\n\n

Monitor voortdurend vakuumdruk onder membrane, oppervlaksettling, poriewaterdruk en horisontale grondverskuiwing. Neem daaglikse data op en pas konstruksietoestande aan op grond van moniteringresultate.<\/p>\n\n\n\n

Stap 9: Losskeping en Aanvaarding<\/strong> <\/p>\n\n\n\n

Lose en skakel toerusting af wanneer konsolidasiegraad, settlement en draakapasiteit aan ontwerpvereistes voldoen en meer as sewe dae stabiel bly. Demonteer fasiliteite, stel dokumentasie op en voltooi voltooiingsaanvaarding.<\/p>\n\n\n\n

Slotwoord<\/strong> <\/p>\n\n\n\n

Vakuumvoorlaai is 'n hoofstroomtegniek vir grootoppervlakte sagtegrondverbetering. Elke werksprosedure bepaal direkte versterkingsprestasie. Streng implementering van gestandaardiseerde werkvloei en streng beheer oor dreinering, se\u00ebling, vakuumpomp en monitering kan kwaliteitrisiko's effektief verminder en verseker dat sagtegrondversterking aan ontwerpverwachtings voldoen.<\/p>\n\n\n\n
