箱梁施工作業(yè)指導(dǎo)書
針對(duì)當(dāng)前我后張箱梁即將開工之即的各種施工情況，為了控制梁體在預(yù)制前后，內(nèi)在、外在質(zhì)量能夠達(dá)到業(yè)主的高標(biāo)準(zhǔn)要求。現(xiàn)對(duì)箱梁施工隊(duì)伍技術(shù)負(fù)責(zé)人員就各具體施工環(huán)節(jié)作如下的作業(yè)指導(dǎo)：
一、指導(dǎo)范圍
該作業(yè)指導(dǎo)書包括后張法20m箱梁的施工、吊運(yùn)及存放。
二、相關(guān)的技術(shù)規(guī)范
（1）XX高速公路《兩階段施工圖設(shè)計(jì)》
（2）《公路工程國內(nèi)招標(biāo)文件范本》
（3）GB1489-98《鋼筋砼及熱軋帶肋鋼筋》
（4）GB13013-91《鋼筋砼及熱軋光圓鋼筋》

三、各階段指導(dǎo)內(nèi)容
1、非預(yù)應(yīng)力鋼筋的制做、成型、綁扎
（1）與圖核對(duì)成品鋼筋的鋼號(hào)、直徑、形狀、規(guī)格尺寸和數(shù)量是否正確無誤，如有遺漏，應(yīng)及時(shí)糾正、增補(bǔ)，并及時(shí)與現(xiàn)場(chǎng)技術(shù)負(fù)責(zé)人取得溝通后方可開始制作。
(2）鋼筋的制做為使其在加工成型后滿足規(guī)范，應(yīng)針對(duì)圖紙?jiān)O(shè)計(jì)型號(hào)、類別分專人專項(xiàng)加工制作。制作時(shí):
a、鋼筋的表面應(yīng)潔凈，使用前應(yīng)將表面油漬、漆皮、鱗銹等清除干凈。
b、鋼筋應(yīng)平直，無局部彎折，成盤的鋼筋
Box girder work instructions
Post-tensioned box girder for the current I that is all about to start the construction of the body to control the beam before and after the prefabricated, internal and external quality of the owners to achieve high standards. Technical teams are on the box girder for construction of staff on specific aspects of the operation guidance as follows:
A guide scope

Third, the contents of each stage guide
1, making non-prestressed reinforcement, molding, banding
(1) finished with the map check the steel reinforcement, diameter, shape, size and quantity specifications are correct and, if missed, should be promptly corrected, updated and timely access and on-site person in charge of communication technology may commence only after production.
(2) reinforcement of the system as to meet the specifications after the molding process should be designed for drawing models, a special category of hand manufacture. Production Time:
a, steel surfaces should be clean, grease the surface before use should, patent leather, scale rust, etc. cleaned.
b, bar should be straight, no local bending into a plate of steel
