Line-soo-saarka dhuumaha buundooyinka prestressed caag ah oo prestressed line-soo-saarka iyo grouting line-soo-saarka tuubooyinka waxaa loo raray macaamiisha Chengdu,
Qingdao Cuishi mashiinnada balaastiigga ah ee soo saara bac caag ah iyo tuubo caag ah
Alaabtan waxaa inta badan loo isticmaalaa dawladda hoose, ilaalinta jiirada, xawaaraha sare ee buundada prestress kacsanaanta balaastikada, tuubada buundada prestressed, wakhtiga shubanka si looga ilaaliyo xadhigga birta wasakhowga, si loo hubiyo xiisada kacsanaantaBacaha prestressed ee tilmaamaha ugu muhiimsan: 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120mm dhumucdiisuna waxay tahay 2.2-3cm
Jaleecada balaastiga ah ee prestressed waa hal darbi oo ay ka soo baxayso caag ka baxaysa caag cufnaanta sare leh ee polyetylen (HDPE) oo loogu talagalay dhismayaasha shubka ah ee daloola ee sida tuubo daloolsan oo leh feeraha hore loo saxay.Waa beddel ku habboon birta asalka ah ee buundada iyo dhismaha dhismaha.Tuubooyinka caaga ah ayaa loo qaybiyaa laba qaybood: tuubooyinka wareegsan iyo tuubooyinka fidsan, kuwaas oo ku xidhan isticmaalka dhabta ah ee noocyada kala duwan ee caagadaha.Walxaha ceeriin ee gambaleelka balaastiga ah ee prespressed waa HDPE.Iska caabbinta daxalka ayaa aad uga fiican tan biraha, kama baqanayso aashitada iyo daxalka alkali, ma daxaleysato lafteeda, waxayna si wax ku ool ah uga ilaalin kartaa feeraha prestressed ee daxalka.

Caagagga caaga ah sida habka post-tensioning prestressed ee walxaha dabada ah waa qayb muhiim ah oo ka mid ah nidaamka prestressed, muddo dheer injineernimada prestressed iyadoo la isticmaalayo biraha birta sida wax dalool ah, si ay uga gudbaan cilladaha biraha biraha shaabadeynta liidata, dhaawac fudud. fududahay in miridhku, iska caabin weyn oo iska caabin ah, laakiin sidoo kale si ay u bixiyaan xannibaad dheeraad ah oo ka hortagga daxalka ee feeraha prestressed, waxaa lagu talinayaa in la isticmaalo polyetylen ama polypropylene ka samaysan casiir caag ah sida wax soo saarka kacaanka oo leh habka post-tensioning si loo hagaajiyo nolosha. ee qaab-dhismeedka
