20、高度鋼筋混凝土防護(hù)柵欄加0.5m刺絲滾籠；高郵特大橋0~518#墩墩臺均高于3m，設(shè)置1.8m鋼筋混凝土立柱金屬網(wǎng)片柵欄。防護(hù)柵欄單元根據(jù)現(xiàn)場實(shí)際情況選用3.0m、1.59m、1.15m三種形式；防護(hù)柵欄由立柱、上檻、下檻、欄片、柱帽構(gòu)件現(xiàn)場拼裝組成。其中地面縱坡小于6地段，采用防護(hù)柵欄長度3m，地面縱坡在6~12地段，采用防護(hù)柵欄長度1.59m，地面縱坡在12~36地段，采用防護(hù)柵欄長度1.15m，各構(gòu)件采用C30鋼筋混凝土預(yù)制，主筋

21、采用HRB335，箍筋及構(gòu)造筋采用HPB300。防護(hù)柵欄應(yīng)在基礎(chǔ)混凝土強(qiáng)度達(dá)到設(shè)計(jì)的80%以上后安裝，安裝應(yīng)牢固。旱橋地段橋下全線封閉，防護(hù)柵欄的每一封閉圈至少設(shè)置兩處單開柵欄門，以方便養(yǎng)護(hù)維修人員作業(yè)，欄門原則每公里一處，根據(jù)實(shí)際情況設(shè)置通道。道路寬度為既有設(shè)施（如道路、水渠等）兩側(cè)各加1m或按照協(xié)議要求確定，增設(shè)通道的寬度原則上不超過8m。防護(hù)柵欄在區(qū)間線路應(yīng)貫通封閉。所有連接螺栓均采用防盜設(shè)計(jì)，由螺桿、螺帽、防盜墊圈組成，安裝及拆

22、卸需使用專門工具，根據(jù)不同連接點(diǎn)的厚度，選用不同尺寸的防盜螺栓。防護(hù)柵欄的安裝應(yīng)滿足有關(guān)規(guī)定要求，應(yīng)根據(jù)有關(guān)規(guī)定進(jìn)行相關(guān)驗(yàn)收。3.1鋼筋混凝土防護(hù)柵欄鋼筋混凝土防護(hù)柵欄1）立柱：防護(hù)柵欄立柱截面尺寸為180180mm，防護(hù)高度2.7m，兩側(cè)設(shè)置10cm長牛角支撐。牛角支撐用以搭接下檻，在設(shè)置防護(hù)柵欄的起點(diǎn)、終點(diǎn)或其他建筑物連接時(shí)，單側(cè)設(shè)牛角支撐。2）上檻高度:125mm、寬180mm，分端部及中間兩種形式，分別用于防護(hù)柵欄起始點(diǎn)位置及中
