前言

本作業(yè)指導書在編制過程中，認真總結我公司馬路馬路建設的實踐經(jīng)驗，學習和借鑒了《鐵道部工法匯編》及其他先進施工經(jīng)驗，以馬路客專質量驗收標準為依據(jù)，重點對施工過程中的工藝、方法、措施和質量控制目標作出了要求，反映了橋梁工程施工過程中的重要工藝環(huán)節(jié)，為各項目的橋梁施工提供指導和參考資料，是我公司橋梁施工的參考性文件。

橋梁篇作業(yè)指導書共分6部分，主要內容包括：橋梁基礎、橋梁墩臺身及框構、橋梁支座及原位澆筑橋梁、橋梁預制及架設、特別橋梁施工、橋梁附屬設施等。

在本作業(yè)指導書匯編實施過程中，希望各單位結合工程實踐，認真總結經(jīng)驗，積累資料，如發(fā)現(xiàn)需要修改放補充之處，請及時將看法和有關資料反饋給我們，供今后修訂時參考。

本作業(yè)指導書主要起草人：陳永平、陳則章、陳紅兵、胡漢忠、高曉玲、劉鵬、趙駿、丁博、王坤、張磊、江飛、王義、陳玉英、范勇、張根華、劉軍科、徐文書、俞祖軍、劉小野、鄭宏偉、李耀華、楊永明、張旭東、唐達昆、施建、劉國雄、方明山、賽鐵兵、王鵬、汪婧。

由于時間緊，章節(jié)多，編制難免存在疏漏，敬請批評指正，以便修訂。

（一）橋梁基礎

人工挖孔樁施工作業(yè)指導書

1適用范圍

適用無地下水或有有少量地下水的土層和風化軟質巖層的樁基施工作業(yè)。2作業(yè)準備

2.1平整場地、清除雜物、夯打密實，修通棄土道路，接通水電，備好機、料具。

2.2做好孔口防排水設施。樁位處地面應高出原地面50cm左右，場地四周開挖排水溝，防止地表水流入孔內。。

2.3施測墩臺及孔位控制中線，做好護樁。護樁必需用砂漿或混凝土進行加固保護，以備開挖過程中對樁位進行檢驗。

2.4對挖孔場進進行圍護，防止土石等雜物滾入孔內。孔口附近堆放相具材料以不增加孔壁壓力為宜。

2.5人員、機械配備（勞動力組織采用內部隊伍組織模式，施工人員要結合現(xiàn)場確定的施工方案、機械、人員組合、工期要求進行合理配置）見表1、表2。
