根成排埋設排水涵管。涵管底部至渠底持平，確保水流通過。其余用素土分層回填到施工平臺面分層夯實，填土高度。整個施工平臺面邊坡用沙袋貼面防護，雨季來臨時如來不及排水；可以直接把施工平臺用挖機挖開確保排洪。現(xiàn)況車輛通行興業(yè)三路的車流量主要為小焦工業(yè)園區(qū)的施工及普通通行車輛，車流量較小，車速在 40km/h左右，大型車輛較多。2．上部結構設計本橋上部結構為預應力混凝土現(xiàn)澆連續(xù)箱梁。現(xiàn)澆箱梁采用流線型等高連續(xù)箱梁，中心處梁高，單箱三室截面，箱梁頂寬 ，橋面橫坡通過箱梁左右腹板高差形成?；炷翉姸鹊燃壘鶠?C50。墩身采用寶瓶式雙柱式橋墩縱橋向墩寬 。8墩頂設固定支座，其余各墩頂設活動支座。（2）橋臺橋臺采用鋼筋砼一字臺，橋臺前墻寬 ，厚 ；臺身寬 ，厚。橋臺混凝土強度等級均為 C40。8墩采用雙排樁基礎，每墩設 4 根 D= 鉆孔灌注樁，樁頂設承臺，承臺長 ，寬 ，厚 。橋臺采用雙排樁基礎，一幅橋臺設 8 根 D= 鉆孔灌注樁，樁頂設承臺，承臺長 ，寬 ，厚 。4．地質情況根據(jù)鉆探揭露，擬建場地地基土自上而下分述如下：①素填土（Qml） ：層厚 ～，頂板埋深 0～，頂板標高○1b～。屬潮濕類型土。坡積成因。該層按《公路工程地質勘察規(guī)范》 （JTGC202022）附錄 J 劃分，土、石等級為Ⅱ級普通土?？傮w屬中濕類型土。④全風化花崗巖（γ52（3）c）⑦：層厚 ～，頂板埋深0～，頂板標高 ～。具有泡水易軟化、崩解的特性。⑤砂礫狀強風化花崗巖（γ52（3）c）⑧：揭露厚度 ～（大多路基孔未揭穿） ，頂板埋深 0～，頂板標高
