前言

本作業(yè)指導(dǎo)書在編制過程中，認(rèn)真總結(jié)我公司馬路馬路建設(shè)的實(shí)踐經(jīng)驗(yàn)，學(xué)習(xí)和借鑒了《鐵道部工法匯編》及其他先進(jìn)施工經(jīng)驗(yàn)，以馬路客專質(zhì)量驗(yàn)收標(biāo)準(zhǔn)為依據(jù)，重點(diǎn)對施工過程中的工藝、方法、措施和質(zhì)量控制目標(biāo)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(xiàng)目的橋梁施工提供指導(dǎo)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(dǎo)書共分6部分，主要內(nèi)容包括：橋梁基礎(chǔ)、橋梁墩臺身及框構(gòu)、橋梁支座及原位澆筑橋梁、橋梁預(yù)制及架設(shè)、特別橋梁施工、橋梁附屬設(shè)施等。

在本作業(yè)指導(dǎo)書匯編實(shí)施過程中，希望各單位結(jié)合工程實(shí)踐，認(rèn)真總結(jié)經(jīng)驗(yàn)，積累資料，如發(fā)現(xiàn)需要修改放補(bǔ)充之處，請及時(shí)將看法和有關(guān)資料反饋給我們，供今后修訂時(shí)參考。

本作業(yè)指導(dǎo)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(dá)昆、施建、劉國雄、方明山、賽鐵兵、王鵬、汪婧。

由于時(shí)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(chǔ)

人工挖孔樁施工作業(yè)指導(dǎo)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(fēng)化軟質(zhì)巖層的樁基施工作業(yè)。2作業(yè)準(zhǔn)備

2.1平整場地、清除雜物、夯打密實(shí)，修通棄土道路，接通水電，備好機(jī)、料具。

2.2做好孔口防排水設(shè)施。樁位處地面應(yīng)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(nèi)。。

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

2.4對挖孔場進(jìn)進(jìn)行圍護(hù)，防止土石等雜物滾入孔內(nèi)?？卓诟浇逊畔嗑卟牧弦圆辉黾涌妆趬毫橐?。

2.5人員、機(jī)械配備（勞動力組織采用內(nèi)部隊(duì)伍組織模式，施工人員要結(jié)合現(xiàn)場確定的施工方案、機(jī)械、人員組合、工期要求進(jìn)行合理配置）見表1、表2。
