Isakhiwo sohlaka lwesikhala esiyisicaba sengadi ye-botanical inobude obuphelele obungamamitha angama-30, ubude obuphelele obungamamitha angama-35.4 kanye nobude obuphelele obungamamitha ayi-155.
1. Uhlobo lwesakhiwo sohlaka lwesikhala sensimbi: ifreyimu yesikhala yensimbi eyisicaba, ukwesekwa kwezwi eliphansi.
2. Isikhathi sereferensi yesakhiwo yiminyaka engama-50, impilo yesevisi yokuklama kwesakhiwo: iminyaka engu-50;izinga lokuphepha kwesakhiwo sesakhiwo: Ikilasi II.
3. Ukuqina kwe-Seismic fortification: 7 degrees, iqembu lesibili lamaqembu okuzamazama komhlaba, ukusheshisa kokuzamazama komhlaba okuyisisekelo: 0.15g.Isigaba se-Seismic fortification: isigaba sokuqina esijwayelekile.
4. Lo mqulu udinga ukwakhiwa ngokuhambisana "Nokudweba Okuyisisekelo Kohlaka Lwegridi Evaliwe Yomsele Wokulayishwa Kwemoto" (T0202) kanye "Nomdwebo Wesakhiwo Womsele Wokulayishwa Kwemoto Ovalelwe" (T0204).
5. Ipayipi lensimbi lohlaka lwegridi: ipayipi elishiselwe imvamisa ephezulu (izinduku ezingezansi φ114, ezingafakiwe), amapayipi ensimbi angenamthungo (izinduku ze-φ114 nangaphezulu);impahla: Q235B, insimbi kufanele ihlangabezane nezinga kazwelonke "insimbi ephansi ye-alloy high-strength structural steel" GB/ T1591;
Futhi kufanele ihlangabezane nezimfuneko zezinto ezibonakalayo "Zokucaciswa Kwesakhiwo Sensimbi".
6. Ibhola le-Bolt: Lenziwe ngensimbi engu-45 ku-"High Quality Carbon Structural Steel" (GB/T 699) ngokufaka ukushisa okushisayo, bese icutshungulwa.
Ingaphezulu kufanele libe bushelelezi, kungabikho imifantu, kungabikho ukushiswa ngokweqile, kungabi ne-pitting.Uchungechunge kufanele luhambisane nezidingo zochungechunge olujwayelekile kokuthi "Basic Dimensions of Ordinary Threads" (GB/T 196), futhi ukubekezelelwa kwentambo kufanele kube yibanga 6H njengoba kucaciswe kokuthi "Okujwayelekile Ukubekezelela Intambo" (GB/T 197).
Ifomu nobukhulu bamabhawodi kufanele kuhlangabezane nezidingo zendinganiso kazwelonke yamanje "Amabhawodi anamandla aphezulu amabholithi egridi yensimbi namajoyinti ebhola" (GB/T 16939).
