Immersed pipe prestressed steel strand cut-off pipe and construction method thereof
The invention relates to the technical field of immersed tube tunnel construction, in particular to an immersed tube prestressed steel strand cut-off pipe and a construction method thereof.The cut-off pipe comprises two straight pipes symmetrically arranged, the two ends of each straight pipe are a first port and a second port, and the first ports communicate with the outside; the connecting pipe is used for connecting the two straight pipes; the two connecting bent pipes are respectively arranged between the two straight pipes and the connecting pipe; the first port and the second port of the straight pipe, the two ends of the connecting pipe and the interior of the connecting bent pipe are all filled with temporary sealing materials capable of preventing cement grout from permeating. The method comprises the following steps: S1, cutting off pipe blanking; s2, blocking and mounting the cut-off pipe; s3, dredging the cut-off pipe; s4, cutting-off preparation of the cutting-off pipe; s5, cutting off the steel strand; the method is easy to operate, the sealing performance of the joint is good, it can be ensured that the cut-off pipe is completely dredged, the problem of blockage of a prestressed duct is technically solved, and the cut-off construction quality of the prestressed pipeline is improved.
本发明涉及沉管隧道施工技术领域，尤其涉及一种沉管预应力钢绞线切断管及其施工方法，切断管包括，包括：两个直管，对称设置，所述直管的两端为第一端口和第二端口，所述第一端口与外部连通；连接管，用于连接两个所述直管；连接弯管，有两个，分别设置于两个直管与连接管之间；所述直管的第一端口、第二端口、连接管的两端、以及连接弯管的内部均填充有能够阻挡水泥浆液渗入的临时密封材料；通过S1、切断管下料；S2、切断管的封堵、安装；S3、切断管疏通；S4、切断管的切断准备；S5、切断钢绞线；本发明操作简单，接头处密封性能良好，能够确保切断管全部疏通，从工艺上解决了预应力孔道堵塞难题，提高了预应力管道切断施工质量。
