Concrete prestressed pipeline grouting vent hole structure and construction method thereof
The invention discloses a concrete prestressed pipeline grouting vent hole structure and a construction method thereof.The concrete prestressed pipeline grouting vent hole structure comprises a prestressed pipeline and an exhaust pipe arranged on the prestressed pipeline, the exhaust pipe comprises a head part and a rod part, the outer diameter of the rod part is smaller than that of the head part, and the rod part is provided with external threads; the rod portion of the exhaust pipe penetrates through the prestressed pipeline from inside to outside, and a nut outside the pipeline is matched with the rod portion to fix the rod portion. The exhaust pipe comprising the head part and the rod part provided with the external threads is adopted as the exhaust hole, the problem that follow-up steel strand pipe penetrating installation is affected due to the fact that an existing bent iron pipe serves as the exhaust hole is solved, the technical requirement for effective exhaust during prestressed pipeline grouting can be met, and the construction quality is improved. The method has the advantages that construction operation is easy and convenient, and the construction cost can be reduced.
本发明公开了一种混凝土预应力管道压浆排气孔结构及其施工方法，所述混凝土预应力管道压浆排气孔结构，包括预应力管道、设在预应力管道上的排气管，所述排气管包括头部和外径小于头部且设有外螺纹的杆部，排气管的杆部从所述预应力管道内往外穿过，在管外用螺帽与杆部配合将杆部固定。本发明采用包括头部和设外螺纹的杆部的排气管作为排气孔，避免了现有弯铁管作为排气孔影响后续钢绞线穿管安装的问题，可满足预应力管道压浆时有效排气的技术要求，提升施工质量。本发明具有施工操作简便，可降低施工成本的优点。
