Auxiliary grouting device for PCCP (prestressed concrete cylinder pipe) mounting joint

The utility model provides a PCCP (prestressed concrete cylinder pipe) installation joint grouting auxiliary device, which comprises an annular steel plate and a grouting pipe, the sealing layer is arranged between the annular steel plate and the outer wall of the pipeline; and the locking piece is used for closing the two free ends of the annular steel plate to form an annular structure. The utility model has the beneficial effects that through the combination of the annular steel plate and the long rubber strip, the PCCP joint gap can be quickly covered, and then the pull hook and the pull ring at the end part of the annular steel plate are closed, so that the device is tightly hooped at a pipeline joint, and mortar can be poured at a grouting opening. The device is easy to assemble and convenient to operate. 本实用新型提供了一种PCCP管道安装接头灌浆辅助装置，包括：环形钢板，利用环形钢板覆盖在管道接口部位；密封层，设置于环形钢板与管道外壁之间；锁紧件，用以将环形钢板的两端自由端闭合，形成环状结构。本实用新型有益效果：通过环形钢板与长橡胶条的组合，能够快速覆盖PCCP接头缝隙，然后闭合环形钢板的端头部拉钩和拉环，使本装置紧箍在管道接口处，即可在灌浆口处进行灌注砂浆。本装置易于组装，操作便捷。
