一、概況
??????? 我單位施工的礦井井井筒工程,目前正在籌備期間,根據(jù)施工設(shè)計要求,需要安裝V型立井鑿井鋼管井架。為了保證施工安全質(zhì)量,特制定此措施。
??????? V型立井鑿井鋼管井架為四層鋼結(jié)構(gòu)井架,其天輪平臺、卸矸臺處按鑿井設(shè)計要求布置提升天輪及梁,各功能天輪及梁和翻矸系統(tǒng),為保障工程施工安全、保質(zhì)、高效地完成,采取井架分為南、北兩部分在地面預(yù)組成兩扇構(gòu)架。利用吊車按設(shè)計要求在地面依次組合。天輪平臺、卸矸臺各設(shè)施在井架組裝完畢后按設(shè)計要求分別安裝。(組裝按《立井鑿井井架圖冊》圖冊進行)
??????? 二、主要技術(shù)參數(shù)
??????? 1、井架地腳基礎(chǔ)中心幾何尺寸:16m×16m;天輪平臺邊梁中心幾何尺寸:7.5m×7.5m。
??????? 2、井架天輪房起重梁距底腳重高為31.198m,天輪平臺距底腳垂高為26.364m。
??????? 3、最重單件:4.073t,井架總重72.368。
??????? 4、下部兩層預(yù)組件總重:(Gi是井架鋼梁G-i的重量,Li是天輪平臺):
??????? Q南=G3+G4+G5+G6+G9+2G10+2G11+G12+4G13+4G14+G15+G16+2G17+2G18+2G26
??????? =1871+1871+2252+2252+561+2×420+2×688+959+4×412+4×155
??????? +360+360+2×648+2×123+2×688
??????? =17888Kg
??????? ≈17.9t
??????????????? 因為南側(cè)的井架鋼梁與北側(cè)的井架鋼梁對稱
??????????????? 所以?????? Q北=17.9t
??????? 5、天輪平臺及第三層預(yù)組件總重(Gi是井架鋼梁G-i的重量,Li是天輪平臺梁L-i的重量):
??????? Q南=G1+G2+G7+2G8++L3
????????????? =504+504+411+2×531+4073
????????????? =6554Kg
????????????? =6.6t
??????? 因為南側(cè)的井架鋼梁與北側(cè)的井架鋼梁對稱
??????? 所以?????? Q北=6.6t
??????? Q東=G7+2G8++L1
????????????? =411+2×531+3137
????????????? =4610Kg
????????????? =4.6t
??????? 因為東側(cè)的井架鋼梁與西側(cè)的井架鋼梁對稱
??????? 所以?????? Q西=4.6t
??????? 6、天輪房架及起重梁總重(Ti是天輪房架及起重梁T-i的重量):
??????? QT=2T1+2T2+4T3+2T4+T5=2×338+2×338+4×471+2×505+204
??????? =4454Kg
??????? ≈4.5t
