Geogrid komgwaqo: isicelo kanye izakhiwo

Minyaka yonke, wabeka futhi kukhandwe nezinto ezithile emakhulwini ezinkulungwane amakhilomitha kwemigwaqo. ukwakhiwa okusha ngokuvamile eyenziwa imithwalo wamanje kanye ubuchwepheshe obusha, kodwa kulungiswe lendwangu olukhona, ngokuchibiyela okuthiwa, babevame izindlela akusebenzi engatheli.

Umphumela wokugcina has a ukhwaliti ongaphakeme. umgwaqo Geogrid - yesimanje impahla isakhiwo yeselula asetshenziswe ukulungisa emikhulu. Ubuchwepheshe ezihilela ukusetshenziswa kwale nto abe high umsebenzi owawenziwa.

Ukusetshenziswa geogrids Road

Ukwakhiwa ezintsha kanye nokuvuselelwa kwemigwaqo ekhona ngezinhloso ezahlukene - egatsheni main lapho geogrid endleleni esetshenziswa. kuye ngokuthi ubuchwepheshe laying kungaba kwenziwe kuzo zonke zamatshe komzila womgwaqo. The main injongo geogrid endleleni:

• Ukuqinisa izigaba lalisalungiswa. Geogrid yehlisele phezu asphalt ezilimele ingxenye kanye ikhava entsha ibekwe phezu kwalo. izakhiwo Bezakhiwe yegridi ugweme ukuxhumana phakathi kwamanzi entsha aqhephukile ubudala. Lapho lesi sendlalelo eqala ingxenye enkulu ekucindezelekeni ovundlile.
• I ezindaweni umthwalo ngobukhulu endleleni bangase bafinyelele nezakhamuzi kanye ukulandelela. Lapho elungisa geogrid sibekwa ekhosombeni phezu wangcwatshwa asphalt ukhonkolo. Lokhu kukuvumela ukuthi usabalalise umthwalo ngokulinganayo phezu yonke indawo, ekuvimbeleni ukwakheka nezakhamuzi entsha.
• geogrid Ukubeka e komzila womgwaqo wenziwa yokuhlanganisa izinhlobo ezahlukene ezinengilazi (isib asphalt, usimende kanye ukhonkolo) ukuze kuvinjelwe ngokuhlaziya.

• Ukuqinisa amalunga omzimba phakathi enezisekelo zikakhonkolo. Lapho usebenzisa i-enamathela asphalt ngesisekelo enezisekelo zikakhonkolo ezindaweni kokuzalela kwakhiwa ubuthakathaka okuyiwona reinforcer web selibekiwe umgwaqo geogrid.
• Lapho ukunwetshwa komgwaqo ngesikhathi kwalapho kuhlangana khona ezinengilazi akhona namasha angase inqamuke. Ukuze uvimbele lokhu, joint luqiniswe geogrid.
• Ubuchwepheshe banamuhla bavame ukunikeza kwangaphambilini inhlabathi ukuqinisa. Iphinde isetshenziswa umgwaqo geogrid. Ukusebenzisa isendlalelo yokugcizelela lapho kwakhiwa blade onguthelawayeka kuyingxenye ebalulekile yenqubo.

Izinhlobonhlobo geogrids kanye nezici zabo

Buka geogrids inquma uhlelo lwayo lokusebenza. Ngaphezu impahla kanye nosayizi cell, zihlukaniswa indlela obumba impahla: biaxial (orientation ezimbili) futhi uniaxial (monoorientirovannye). imikhiqizo Biaxial nge amaseli unxande eyenzelwe nokwakhiwa kwemigwaqo, kuhlanganise emhlabathini esithambile. Geogrids orientation ombaxambili umthwalo basakaza kahle, okwandisa esaphila. ungqimba Uniaxial lamaseli side ibe namandla eqine okusezingeni eliphezulu, enhle kakhulu eqinisa inhlabathi, ukuguguleka kwenhlabathi kanye izisekelo obsypnyh.

Imikhiqizo ye-Ukuqinisa asphalt ukhonkolo

Geogrid ngoba Ukuqinisa asphalt komgwaqo ukhonkolo ikuvumela ukuthi usabalalise umthwalo yangaphandle wendawo phezu wawuqeda wonke lo mqulu indwangu eseduze. Lokhu kwaziswa kusetshenziswa ukunweba ukuphila emikhulu nge isizinda ukhonkolo, okuyinto minyaka yonke kuba more. Futhi, lolu anezikhala ihambisa ekucindezelekeni yangaphakathi ezisuka kusukela ukuncipha kancane kancane lukhuni ukhonkolo.

ukuqinisa Ukhonkolo Metal anezikhala esifushane futhi kuyabiza. Fiberglass futhi polymer geogrids Uyi okunye eshibhile kuya ukuqinisa metallic futhi ube ngesikhathi esifanayo zonke izici ezidingekayo:

• Material lwezihloko ezinjalo kuba inert amakhemikhali, asiphazanyiswa lokushisa ekushintshashintsheni nokhonkolo ane-alikhali imvelo.
• It has a ikhono eliyingqayizivele lokusakaza imithwalo wendawo.
• It has a isisindo ongaphakeme, ukuphila isikhathi eside, ukufakwa lula futhi intengo imali.

Ukuze uthuthukise ukusebenza substrate esetshenziswa ukwakha imigwaqo, asphalt isingathwa.

Geogrid ukuba kwakhiwe umgwaqo

Gandelwe nsuku zonke ngaphansi imithwalo ezokuthutha ukusakaza, okuyinto nakanjani kuholela ekubhujisweni kwaso kanye kumiswa imigodi, izimbobo nokusasamba. Isizathu esiyinhloko - yokuntuleka ngezizathu ukuqeqeshwa. umgandayo Geogrid ivumela asphalt ukwandisa izici ngamandla kuwebhu, esisuka ukumelana nokwandisa umbono ukucindezeleka ovundlile.

Ukusetshenziswa izinto ezifana nokwakhiwa kwemigwaqo emisha kanye nokulungiswa ekhona kungaba ngokuphawulekayo ngcono ukusebenza bese andise ukuphila umgwengwezi. Ukusetshenziswa geogrids ukuba kwakhiwe umgwaqo lihambisana geotextile kunciphisa ekwakhiweni kwemigwaqo kuyadingeka ivolumu non-metallic ngobuningi izinto, okuyinto kakhulu ukunciphisa izindleko zalo msebenzi, ngaphandle kokushintsha izinga design.

polymer geogrids

umgwaqo Geogrid ka -polyester Imicu yotshani nge enamathela polymer zenziwe nitevyazalnoy futhi tufting ubuchwepheshe. Lokhu kuvumela ukugcina kokuqala impahla amandla aphezulu. Isakhiwo geogrids - fixed usayizi cell, okuyinto engcono kakhulu kunaleyo egcwele impahla yabo. Nale ukugcwaliswa wasithukuthelela isisekelo (inhlabathi, idwala, omunye isisekelo izinto ezisetshenziselwa ukwakha).

izinto Polymeric zisetshenziswa njengendlela ungqimba yokugcizelela ezingqimbeni engezansi isisekelo komgwaqo. Ukusetshenziswa amanethiwekhi polymeric e ukwakhiwa kwemigwaqo ivumela ukuqinisa base komgwaqo futhi kuvimbele interpenetration zezinto ixhumana izingqimba ezahlukene. Okhulisa ibangelwa nokukhawulela ukuhamba base elimbudumbudu ngobuningi impahla ngaphandle cell. I kwakhiwa ungqimba esiyinhlanganisela (impahla luyimbudumbudu + geogrid) siye sathuthukisa ukumelana imithwalo ashukumisayo.

fiberglass Imikhiqizo

Geogrids esekelwe ingilazi Imicu yotshani ezisetshenziswa njengeziwusizo yokugcizelela izakhi futhi izingqimba zokuzivikela esasihlukanisa ukwakhiwa nokulungiswa kwemigwaqo yombuso kanye zesifunda, airfields, amabhuloho futhi overpasses. Ukusetshenziswa ingilazi fibre ukugcizelela grid ngoba asphalt ezinengilazi kungandisa isikhathi ezisebenza phakathi overhauls 2-3. Izindleko nokuvuselelwa kwemigwaqo ezindaweni lapho fiberglass geogrids asetshenziswa ngenkuthalo, kwehle ngo-40%. izinto ezinjalo abe nezici okusezingeni eliphezulu lobuchwepheshe-ngokomzimba: ukumelana abezindaba nolaka, ikhono lokubekezelela transverse okusezingeni eliphezulu okuseqophelweni longitudinal. Geogrids fiberglass ngcono kakhulu amandla futhi izakhiwo mechanical nokuqinisa izakhi.

ukukhiqizwa

Kuze kube manje, ekhiqizwa lezi zinhlobo ezilandelayo eyinhloko geogrids:

• polymer extruded;
• fiberglass laminated;
• Ukwethula anezikhala of polyester zemicu ingilazi zesivikelo sesifuba.

ubuchwepheshe besimanje futhi imishini nge kokuhlukana ebanzi izindlela zokukhiqiza uvumele ukukhiqiza geogrid nge izakhiwo ezahlukene ngezinto ezahlukene kanye zalapho ezahlukene ifindo. Izimfuneko main kulokhu yilezi:

• ukumelana yizici zemvelo;
• ukumelana nesimo nodlame ngaphansi kwezimo yokusebenza;
• Ukumelana UV;
• ukumelana soiling;
• amandla nokuqina izakhiwo.

Kukhethwa impahla

Of ezihlukahlukene izinhlobo geogrids nosayizi yabo kufanele esekelwe kukhethwa uya khona, inqubo ukwakheka kwamangqamuzana futhi uhlobo impahla eluhlaza. I interlayers zenzelwe ukuqinisa, ukuhlukana kwazo izingqimba, ukulawula ukuguguleka komhlabathi, lokulinganisa kanye izisekelo. Njengoba kuchazwe injongo, kuzomele ukhethe uhlobo oluthile geogrid futhi ubukhulu bawo. Kuye impahla eluhlaza izakhiwo isici akhethiwe, okungase amelana hydro-, bio-, ezishisayo kanye himvozdeystviyu.
