Injongo yokwakhiwa kwengqumba yombhobho wentsimbi kukudlulisa umthwalo wesakhiwo esingaphezulu ukuya kumaleko onzulu womhlaba onesakhono sokuthwala esomeleleyo okanye ukudibanisa umaleko obuthathaka womhlaba ukuze kuphuculwe umthamo wokuthwala kunye nokubumbana komhlaba wesiseko. Ngoko ke, ukwakhiwa kweemfumba zepayipi kufuneka kuqinisekiswe. umgangatho, ngaphandle koko isakhiwo siya kungazinzi. Amanyathelo okwakha imfumba yombhobho ngala:

1. Uphononongo kunye nokumisela: Injineli yovavanyo ibeka iimfumba ngokwemephu eyilelwe indawo yemfumba kwaye iphawule iindawo zokufumba ngeemfumba zomthi okanye uthuthu olumhlophe.

2. Umqhubi wengqumba umi endaweni yakhe: Umqhubi wengqumba umi endaweni yakhe, lungelelanisa indawo yengqumba, kwaye enze ulwakhiwo ngokuthe nkqo nangokuzinzileyo ukuqinisekisa ukuba alutyekeki okanye alushukumi ngexesha lolwakhiwo. Umqhubi wengqumba ubekwe kwindawo yengqumba, phakamisa ingqumba yombhobho kumqhubi wengqumba, emva koko ubeke isiphelo sengqumba kumbindi wendawo yokuma, phakamisa imasti, kwaye ulungise umgangatho kunye neziko lengqumba.

3. Ingcebiso yemfumba yokuwelda: Thatha umzekelo wencamba yemfumba esetyenziswa ngokuqhelekileyo. I-tip ye-cross pile ibekwe kwindawo yemfumba emva kokuqinisekiswa, kwaye i-plate yesiphelo esezantsi ye-pimple yecandelo lombhobho idityaniswe kwiziko layo. Ukuwelda kwenziwa kusetyenziswa i-CO2 ekhuselekileyo ye-welding. Emva kwe-welding, Iingcebiso zemfumba zipeyintwe nge-asphalt echasene nokubola.

4. Ukubonwa komgangatho othe nkqo: Lungisa ubude bokwandiswa kwentonga yeplagi yeoli yesilinda somlenze womqhubi wepile ukuze uqinisekise ukuba iqonga lomqhubi wengqumba likwinqanaba. Emva kokuba ingqumba ibe ngama-500mm emhlabeni, misela ii-theodolite zibe mbini ngokweendlela ezilinganayo ukulinganisa ukuthe tye kwengqumba. Impazamo kufuneka ingabi ngaphezu kwe-0.5%.

5. Ukucinezela imfumba: Ingqumba inokucinezelwa kuphela xa amandla ekhonkrithi emfumba afikelela kwi-100% yamandla oyilo, kwaye imfumba ihlala nkqo ngaphandle kokungaqhelekanga phantsi kokuqinisekiswa kwe-theodolite ezimbini. Ngexesha lokucinezela imfumba, ukuba kukho iintanda ezinzulu, ukuthambeka, okanye ukuphambuka ngequbuliso komzimba wengqumba, imfumba inokucinezelwa. Ukwakhiwa kufuneka kumiswe ukuba izinto ezinje ngokushukuma kunye notshintsho olukhulu ekungeneni lwenzeka, kwaye ukwakhiwa kufuneka kuqaliswe emva kokuphatha. Xa ucinezela inqwaba, nikela ingqalelo kwisantya semfumba. Xa imfumba ingena kumaleko wesanti, isantya kufuneka sikhawuleziswe ngokufanelekileyo ukuqinisekisa ukuba incam yemfumba inamandla athile okungena. Xa i-bearing layer ifikelelwe okanye uxinzelelo lwe-oyile lunyuka ngesiquphe, ingqumba kufuneka ithothe isantya esicinezelayo ukuthintela ukophuka kwemfumba.

6. Uxhulumaniso lwemfumba: Ngokuqhelekileyo, ubude bombhobho wecandelo elinye abudluli kwi-15m. Ukuba ubude bemfumba obuyilelwe bubude kunobude becandelo elinye, uxhulumaniso lwemfumba luyafuneka. Ngokuqhelekileyo, inkqubo ye-welding yombane isetyenziselwa ukudibanisa ukudibanisa imfumba. Ngexesha le-welding, abantu ababini kufuneka badibanise ngokulinganayo ngaxeshanye. , iiwelds kufuneka ziqhubeke kwaye zizele, kwaye kungabikho ziphene zokwakha. Emva kokuba udibaniso lwemfumba lugqityiwe, kufuneka luhlolwe kwaye lwamkelwe phambi kokuba ukwakhiwa kwenqwaba kuqhubeke.

7. Ukutya kweemfumba: Xa imfumba icinezelwe ukuya kwi-500mm ukusuka kwindawo yokuzalisa, sebenzisa isixhobo sokutya imfumba ukucinezela imfumba ekuphakameni koyilo, kwaye ukwandise uxinzelelo olusisigxina ngokufanelekileyo. Ngaphambi kokutyiswa kwemfumba, ubunzulu bokutya kweemfumba kufuneka bubalwe ngokweemfuno zoyilo, kwaye ubunzulu bokutya kweemfumba kufuneka bubalwe ngokweemfuno zoyilo. Phawula isixhobo. Xa ingqumba isiwa malunga ne-1m ukusuka kumphakamo wokuyilwa, umacanda-mhlaba uyala umqhubi wengqumba ukuba acuthe isantya sokuqhuba imfumba kwaye alandelele kwaye aqwalasele imeko yokuhanjiswa kweemfumba. Xa ukuhanjiswa kwemfumba kufikelela ekuphakameni koyilo, umqondiso uthunyelwa ukumisa ukuhanjiswa kwemfumba.

8. Imfumba yokugqibela: Ukulawulwa kabini kwexabiso loxinzelelo kunye nobude bemfumba bufunekayo ngexesha lokwakhiwa kweemfumba zobunjineli. Xa ungena kwi-bearing layer, ulawulo lobude bemfumba yindlela ephambili, kunye nokulawulwa kwexabiso loxinzelelo kukuncedisa. Ukuba kukho naziphi na izinto ezingaqhelekanga, iyunithi yoyilo kufuneka yaziswe ngokuphathwa.
