波形梁鋼護欄施工步驟詳細介紹

更新日期:2018-12-19 點擊量: 作者:層遠護欄

一、 施工工序 

  測量放樣 → 立柱定位 → 立柱安裝 → 立柱豎直度校正 → 波形梁安裝 → 調整波形梁線形 → 擰緊緊固件 → 交工

二、施工過程重難點控制 

  1)在進行填方段高邊坡土路肩護欄施工時,必須提前提醒施工人員注意安全,盡可能避免施工人員在護欄外側施工,休息期間盡量遠離土路肩。 

  2)特別強調在進行護欄拼接螺栓安裝過程中,嚴禁敲擊螺栓,防止敲擊螺栓時拼接螺栓反彈,傷及施工人員。正確方法為采用鋼釬調整護欄板搭接錯位,調整至上下搭接板拼接螺孔相互對齊后,再安裝拼接螺栓。 

  3)根據施工圖進行立柱放樣,縱向以路線各段橋梁、通道、明板涵、中央分隔帶開口和路線交叉等為放樣控制點,橫向以路基中線測量點為準,進行測距定位。放樣時可利用調節板調整間距,并利用分配方法處理零頭數;如遇立柱所處位置設有地下通訊管線、排水管等,尤其是蓋板涵(暗板涵)涵洞頂部埋土深度不足時,應提前進行預警標記,以便立柱安裝時根據現場情況進行處理。 

  4)立柱安裝時,需一人操作打樁機,一人用定位標桿控制立柱間距,一人配合打樁機在安裝過程中利用定位直角卡尺控制立柱橫向位置和標高,用水平尺控制立柱豎直度,一人觀察線形?;ハ嗯浜蠈α⒅?、傾斜、彎曲等情況及時予以糾正。 

  5)波形梁立柱安裝施工中難點是三波波形梁護欄方管立柱安裝,因方管沒有圓管的旋轉調整能力,對立柱的定位要求高,所以必須嚴格控制立柱的標高、間距、豎直度和中絲孔位。 

  6)立柱安裝施工過程中應注意端頭、護欄設置型式和鋼護欄與混凝土護欄連接過渡段施工,以填挖路基交界處填挖零點為護欄端頭起、終點位置,應按設計規定的坐標進行施工。 

  7)針對立柱安裝路基段施工中出現的壞樁或高樁問題,嚴禁采用現場切割的辦法處理。正確處理辦法為:首先應將壞樁或高樁拔除,其次利用變化設置間距重新定位安裝,或者報告現場監理根據地基情況采取人工開挖基礎預埋立柱施工。暗板涵涵洞頂部施工,嚴禁盲目施工導致將洞頂打穿。應根據現場埋深情況采取人工開挖基礎預埋立柱施工。

  8)在遇到道路有上跨主線橋梁的橋墩時,及時向現場監理報告,按照監理確定的設置型式進行施工,對橋墩進行防護。 

  9)在進行預埋立柱迫緊器或套筒時,重點保證承座器或套筒安裝的標高和豎直度以及相鄰間距均要符合設計要求,確保后期波形梁順利安裝。 

  10)波形梁通過拼接螺栓相互拼接,并由連接螺栓通過防阻塊固定于立柱上。 

  11)波形梁安裝施工時對立柱間距不均勻的,應選用合適的調節板安裝,嚴禁切割護欄板。 

  12)護欄線形調整完成后,方可緊固連接螺栓和拼接螺栓。 

(8) When the pier of a bridge spanning the main line on the road is encountered, the site supervision report shall be made promptly, and the construction shall be carried out according to the set-up type determined by the supervision, so as to protect the pier.

9) When carrying out the pre-embedded column press or sleeve, it is important to ensure that the elevation and verticality of the bearing or sleeve installation and the adjacent spacing meet the design requirements to ensure the smooth installation of the wavy beam in the later period.

10) The corrugated beams are joined together by splicing bolts, which are fixed on the posts through an anti-blocking block.

11) If the spacing between the columns is not uniform during the installation and construction of the corrugated beam, the appropriate adjusting plate shall be selected for installation, and the cutting of the guardrail plate shall be strictly prohibited.

12) after the alignment of the guardrail is completed, the connecting bolts and splicing bolts can be fastened.)
