具體(ti)實施方式
四川都江堰至汶j 11高速公路廟子坪岷江大橋總體布置為2 X 50m (簡支T梁)+ (125+220 + 125) m連續剛構+ 17X 50m (簡支T 梁)，橋梁全長1440. 22m。廟子坪岷江大橋設計地震基本烈度為W度。 2008年5月12日發生汶川8. 0級大地震，震中最大烈度達到XI度，廟子坪岷江大橋距震中約7公里。總體來說，廟子坪岷江大橋經受住了汶川8. 0級大地震的考驗，但由于地震烈度過大，橋位處約為X度，地震持續時間大于80s,震后經檢測發現大橋5#墩墩底部以上2m處 (水下80m)及墩底向上第一道橫隔板(水下68m)處均出現了裂紋，需要對其實施修復加固。經多方過反復論證后，采用先在出現問題的 5#橋墩外周邊一定范圍內安設鋼圍堰，然后在橋墩外壁和鋼圍堰間澆注水下砼的方法來對其進行加固加。由于大橋所在位置屬于紫坪浦電站的庫區，大型吊機無法到達，采用了本發明的水下橋墩加固用鋼圍堰的施工方法對加固用鋼圍堰進行下沉施工。本發明的水下橋墩加固用鋼圍堰的施工方法，用懸掛于橋梁梁體 1上的鋼架2完成水下橋墩3加固用鋼圍堰4的現場散拼及整體下沉施工。本發明的水下橋墩加固用鋼圍堰的施工方法，其施工步驟如下A、根據需要加固的橋墩3的截面特征及鋼圍堰4的特征設計并加工鋼架2;B、在需要加固的橋墩3的頂部的橋梁梁體1上安設吊帶11并完成鋼架2的安裝；C、用吊機5將橫橋向鋼圍堰塊段6逐塊吊裝并懸掛于鋼架2上；D、用吊機5將順橋向鋼圍堰塊段7逐塊吊裝并懸掛于鋼架2上；E、完成懸掛于鋼架2上的鋼圍堰4塊段間的連接并在鋼圍堰4 內壁設置導向裝置8;F、在鋼架2及鋼圍堰4上安裝鋼圍堰下沉用滑車組9;G、啟動鋼圍堰下沉用滑車組9將鋼圍堰4下沉就位。上述的水下橋墩加固用鋼圍堰的施工方法，組成鋼架2的鋼梁10由鋼箱梁構成。上述的水下橋墩加固用鋼圍堰的施工方法，施工步驟B是在需要加固的橋墩3的頂部的橋梁梁體1上鉆孔或用其上原有的施工預留孔作為鋼架吊帶ll的吊帶孔，吊帶ll穿過吊帶孔，上端錨固在梁體l 內部，下端與鋼架2連接，根據鋼圍堰4的分塊情況在鋼架2上安裝手動滑車12。上述的水下橋墩加固用鋼圍堰的施工方法，施工步驟C是在完成鋼架2安裝后，用置于橋面13上的吊機5將橫橋向鋼圍堰塊段6起吊后從橋墩3的順橋向外側向下放至鋼架2的橫橋向鋼梁14的端頭以下1 2m處，用懸掛于橫橋向鋼梁14端部的手動滑車12將橫橋向鋼圍堰塊段6吊住，調節手動滑車12將橫橋向鋼圍堰塊段6蕩移至設計位置，如此反復以完成橫橋向鋼圍堰塊段6的吊裝。上述的水下橋墩加固用鋼圍堰的施工方法，施工步驟D是在完成橫橋向鋼圍堰塊段6的吊裝后，用置于橋面13上的吊機5將順橋向鋼圍堰塊段7起吊后從橋墩3的順橋向外側向下放至鋼架2的順橋向鋼梁15以下1 2m處，用懸掛于順橋向鋼梁15上的手動滑車12將順橋向鋼圍堰塊段7吊住，如此反復以完成順橋向鋼圍堰塊段7的吊裝。上述的水下橋墩加固用鋼圍堰的施工方法，施工步驟E是在完成順橋向鋼圍堰塊段7吊裝后，通過調節手動滑車12將順橋向鋼圍堰塊段7和橫橋向鋼圍堰塊段6調節就位，連接順橋向鋼圍堰塊段7和橫橋向鋼圍堰塊段6形成鋼圍堰4，在鋼圍堰4的內側設置導向裝置 8。上述的水下橋墩加固用鋼圍堰的施工方法，施工步驟F是在完成鋼圍堰4的組拼后，在鋼架2的角點處設置定滑車組16，在定滑車組16正下方的鋼圍堰4角點處設置動滑車組17，用鋼繩18連接定滑車組16與動滑車組17，鋼繩18的一端固定在定滑車組16上，另一端與安置在橋面13上的巻揚機19連接，完成圍堰下沉用滑車組9 的安裝。上述的水下橋墩加固用鋼圍堰的施工方法，施工步驟G是在完成圍堰下沉用滑車組9的安裝后，先啟動巻揚機19，收緊鋼繩18，使圍堰下沉用滑車組9將鋼圍堰4吊住，拆除手動滑車12，然后放松鋼繩18將鋼圍堰4下沉就位，最后抽去鋼繩18完成鋼圍堰4的施工。上述的水下橋墩加固用鋼圍堰的施工方法，置于橋面13上的吊機5為汽車吊機。實施例2.本發明的水下橋墩加固用鋼圍堰的施工方法，除先在鋼架2上完成鋼圍堰4的第一節段組拼，用鋼圍堰下沉用滑車組9將鋼圍堰4的第一節段下放入水或向其內注水使其頂面處于水面以上1 1. 5m，然后在鋼架2上完成鋼圍堰4的第二節段的組拼，用圍堰下沉用滑車組 9將鋼圍堰4的第二節段向下放，直至第二節段的底面位于第一節段的頂面處后完成第一節段和第二節段間的連接并入水下沉至第二節段的頂面處于水面以上1 1.5m，如此反復，直至完成整個鋼圍堰4 全部節段的組拼外其余均與實施例1相同。實施例3.本發明的水下橋墩加固用鋼圍堰的施工方法，除組成鋼架2的鋼梁10由型鋼組合梁構成，置于橋面13上的吊機5為履帶吊機外其余均與實施例l相同。實施例4.本發明的水下橋墩加固用鋼圍堰的施工方法，除組成鋼架2的鋼梁10由鋼管梁構成，置于橋面13上的吊機5為龍門吊機外其余均與實施例l相同。實施例5.本發明的水下橋墩加固用鋼圍堰的施工方法，除組成鋼架2的鋼梁10由鋼桁架梁構成外其余均與實施例1相同。實施例6.本發明的水下橋墩加固用鋼圍堰的施工方法，除吊帶11穿過吊帶孔，上端錨固在梁體1頂面外其余均與實施例1相同。
