Iindlela zokunyanga komhlaba kunye neemfuno zeeprojekthi zekhonkrithi zesamente zihambelana neemfuno zeempawu zobunjineli.Ke ngoko, izixhobo kunye neendlela zokwakha ezisetyenziswayo zahlukile ngokweemfuno zeprojekthi.Injongo ephambili ye-bridge deck chiseling kukusombulula ingxaki yokubambelela phakathi kweeleyile.I-slurry edadayo yedekhi yebhulorho yesamente yeyona nto ibangela ukusilela kwedekhi yebhulorho engangeni manzi, ukusilela kokudityaniswa kwe-interlayer kunye nokungaphumeleli kwedekhi yebhulorho.Ngoko ke, ukuba i-bridge deck laitance ayinqunyulwanga ngokupheleleyo, phantsi kwesenzo somthwalo wokuqhuba kunye nokungcangcazela, i-laitance iya kubangela ukusilela kwe-delamination ngenxa yokunganyangeki kwe-shear, kwaye iya kuphuka phantsi kwesenzo sokhukuliseko lwamanzi, okukhokelela ekutshatyalaliswa umaleko wekhonkrithi ye-asphalt ephezulu..

1. I-Bridge deck chiseling akufanele isuse kuphela i-laitance, kodwa iphinde ifake umphezulu ongalinganiyo, oko kukuthi, umahluko phakathi kweencopho kunye nemijelo yomphezulu emva kokucocwa, ixabiso le-mil kufuneka libe likhulu, kuphela ngale ndlela inokuthi iileya. zibopheni ngokuqinileyo.Ukuchetywa komaleko wesiseko sepavumente engqongqo Ubunzulu bokusika kunye neemfuno zokusebenza zomaleko wesiseko sendlela egangathiweyo owomeleleyo phambi kokubeka ikhonkrithi ye-asphalt, kunye neemfuno zesixhobo sokutshiza kunye nomgangatho webhulorho.

2. Injongo yolu nyango lomphezulu lumbini kukwenza i-asphalt ikhonkrithi kunye nomgangatho wesiseko ukwazi ukubopha ngokuqinileyo, kunye nokuthintela ukuntywila kwamanzi, eyokuqala kukutshiza ipavumente egudisiweyo yesamente endala ibe yindawo erhabaxa, le yokugqibela. Kukususa iimpawu zamatayara kumgaqo weenqwelo-moya.Injongo yezi zimbini kukulungisa nokubuyisela i-anti-skid kunye nokuphucula ngokufanelekileyo ukukwazi ukuxhathisa ukungcangcazela kunye nokuguqulwa.

3. Ukutshizwa kwepavumente yesamente kunye nomgaqo weenqwelo-moya wesikhululo seenqwelo-moya Imfuno yokutshizwa yendlela yesamente kunye nomgaqo weenqwelo-moya wesikhululo seenqwelo-moya kukuthintela izithuthi ekutyibilikeni xa ziqhuba naxa zimisa.
