Amaphuzu abalulekile okuqalisa ukuhlolwa kwe-pile foundation

Isikhathi sokuqala sokuhlolwa kwesisekelo senqwaba kufanele sihlangabezane nemibandela elandelayo:

(1) Amandla kakhonkolo wenqwaba ehloliwe akufanele abe ngaphansi kuka-70% wamandla okuklama futhi akufanele abe ngaphansi kuka-15MPa, kusetshenziswa indlela yokucindezeleka kanye nendlela yokudlulisa i-acoustic ukuze kuhlolwe;

(2) Ngokusebenzisa indlela yokumba ewumgogodla wokuhlola, iminyaka yokukhonkolo yenqwaba ehloliwe kufanele ifinyelele izinsuku ezingama-28, noma amandla ebhulokhi yokuhlola elashiwe ngaphansi kwezimo ezifanayo kufanele ahlangabezane nezidingo zamandla okuklama;

(3) Isikhathi sokuphumula ngaphambi kokuhlolwa komthamo ojwayelekile wokuthwala: isisekelo sesihlabathi ngeke sibe ngaphansi kwezinsuku eziyi-7, isisekelo sodaka akufanele sibe ngaphansi kwezinsuku eziyi-10, inhlabathi ehlangene engaxutshiwe ngeke ibe ngaphansi kwezinsuku eziyi-15, nomhlabathi ohlangene osuthisiwe ngeke ngaphansi kwezinsuku ezingama-25.

Inqwaba egcina udaka kufanele yandise isikhathi sokuphumula.

Indlela yokukhetha yezinqwaba ezihloliwe zokuhlolwa kokwamukelwa:

(1) Izinqwaba ezinekhwalithi engabazekayo yokwakha;

(2) Izinqwaba ezinezimo ezingavamile zesisekelo sendawo;

(3) Khetha ezinye izinqwaba ze-Class III ukuze zithwale ukwamukelwa kwamandla;

(4) Iqembu lokuklama libheka izinqwaba ezibalulekile;

(5) Izinqwaba ezinamasu ahlukene okwakha;

(6) Kunconywa ukukhetha ngokufanayo nangokungahleliwe ngokwemithethonqubo.

Lapho wenza ukuhlolwa kokwamukela, kuyancomeka ukuthi uqale uhlole ubuqotho bomzimba wenqwaba, kulandele ukuhlolwa komthamo.

Ukuhlolwa kobuqotho bomzimba wenqwaba kufanele kwenziwe ngemva kokumbiwa komgodi wesisekelo.

Ubuqotho bomzimba wenqwaba buhlukaniswa ngezigaba ezine: izinqwaba zeSigaba I, izinqwaba zeSigaba II, izinqwaba zeClass III, nezinqwaba zeSigaba IV.

Umzimba wenqwaba ye-Type I uphelele;

Izinqwaba ze-Class II zineziphambeko ezincane emzimbeni wenqwaba, ezingeke zithinte umthamo ojwayelekile wokuthwala wesakhiwo senqwaba;

Kunokukhubazeka okusobala emzimbeni wenqwaba yezinqwaba ze-Class III, ezinomthelela kumthamo wokuthwala wesakhiwo womzimba wenqwaba;

Kunokukhubazeka okungathi sína emzimbeni wenqwaba yezinqwaba ze-Class IV.

Inani lesici lomthamo wokuthwala ocindezelayo ome mpo wenqwaba eyodwa kufanele lithathwe njengo-50% womthamo wokugcina wokuthwala okucindezelayo omile wenqwaba eyodwa.

Inani lesici lomthamo omile wokudonsa wokukhipha wenqwaba eyodwa kufanele uthathwe njengo-50% womthamo wokugcina wokudonsa wokuphuma oqondile wenqwaba eyodwa.

Ukunqunywa kwenani lesici somthamo wokuthwala ovundlile wenqwaba eyodwa: okokuqala, lapho umzimba wenqwaba ungavunyelwe ukuqhekeka noma isilinganiso sokuqiniswa kwenqwaba yenqwaba ye-cast-in-place ingaphansi kuka-0.65%, izikhathi ezingu-0.75 kunezingqimba. umthwalo obalulekile uzothathwa;

Okwesibili, izinqwaba zikakhonkolo eziqinisiwe eziqinisiwe, izinqwaba zensimbi, kanye nezinqwaba ezifakwe endaweni enesilinganiso sokuqinisa esingekho ngaphansi kuka-0.65%, umthwalo ohambisana nokufuduka okuvundlile endaweni ephakeme yenqwaba yomklamo uzothathwa njengezikhathi eziyi-0.75 (evundlile. inani lokufuduka: 6mm kumabhilidi azwelayo ekufudukeni okuvundlile, 10mm kumabhilidi angezwani ukususwa endaweni evundlile, ukuhlangabezana nezidingo zokumelana nokuqhekeka komzimba wenqwaba).

Uma usebenzisa indlela yokumba ewumgogodla, izidingo zenombolo kanye nendawo yenqwaba ngayinye ehloliwe zimi kanje: izinqwaba ezinobubanzi obungaphansi kuka-1.2m zingaba nezimbobo ezingu-1-2;

Inqwaba enobubanzi obungu-1.2-1.6m kufanele ibe nezimbobo ezi-2;

Izinqwaba ezinobubanzi obungaphezu kuka-1.6m kufanele zibe nezimbobo ezi-3;

Indawo yokumba kufanele ilingane futhi ihlelwe ngokulinganayo phakathi kwebanga (0.15~0.25) D ukusuka maphakathi nenqwaba.
