Highway T-beam hogging moment grouting exhaust observation pipe
The invention discloses a highway T-beam hogging moment grouting exhaust observation pipe which is applied to a T-beam hogging moment prestressed steel strand laying duct grouting process. A T-beam comprises a bottom bent cap, beam plates erected between adjacent bent caps, grouting pipelines between the two beam plates above the same bent cap, and continuous end pouring pieces filled between twobeam plates above the same bent cap; steel strand laying hole channels are formed in the two ends of each beam plate correspondingly, and the two ends of each grouting pipeline communicate with the corresponding steel strand laying hole channels and are used for steel strand laying and grouting; and the bottom of each observation pipe is fixed to the highest point of the middle of each grouting pipeline, and the top of the observation pipe extends upwards to form a continuous end pouring piece. After the observation pipes are used, the duct grouting time of each span of bridge hogging moment steel strand is shorter than 380 min, and the grouting compactness of the pipeline grouting quality detection result can reach 95% or above.
本发明公开了一种高速公路T梁负弯矩注浆排气观察管，应用于T梁负弯矩预应力钢绞线布设孔道压浆工艺，所述T梁包括底部盖梁，架设在相邻盖梁之间的梁板，同一盖梁上方的两梁板之间注浆管道，和填充在同一盖梁上方的两梁板之间的连续端浇筑件；所述梁板两端分别设有钢绞线布设孔道，注浆管道两端则与对应的钢绞线布设孔道连通、用于钢绞线布设和注浆；所述观察管底部与注浆管道中部最高点固定，观察管顶部向上延伸出连续端浇筑件。使用该观察管后，每跨桥梁负弯矩钢绞线布设孔道压浆时间小于380min，且管道压浆质量检测结果注浆密实度可达到95％以上。
