通风管道伸缩节技术是一种管道非开挖局部套环修理方法。该技术采用的主要材料为环状橡胶止水密封带与不锈通风管道伸缩节,在管道接口或局部损坏部位安装橡胶圈双胀环,通风管道伸缩节就位后用2~3 道通风管道伸缩节固定,达到止水目的。通风管道伸缩节施工速度快,质量稳定性较好,可承受接口错位,止水套环的抗内压效果比抗外压要好,但对水流形态和过水断面有影响在排水管道非开挖中,通常与钻孔注浆法联合使用。

The technology of expansion joint of ventilation pipeline is a non excavation method for repairing local casing ring of pipeline. The main materials used in this technology are the annular rubber water stop sealing belt and the stainless ventilation pipe expansion joint. The rubber ring double expansion ring is installed at the pipe interface or local damaged parts. After the ventilation pipe expansion joint is in place, it is fixed with 2 ~ 3 ventilation pipe expansion joints to achieve the purpose of water stop. The expansion joint of the ventilation pipeline has fast construction speed, good quality stability, and can withstand the dislocation of the interface. The anti internal pressure effect of the water stop collar is better than that of the external pressure, but it has an impact on the water flow pattern and the cross-section. In the non excavation of the drainage pipeline, it is usually used in combination with the drilling grouting method.

通风管道伸缩节主要用来大口径管道(管径不小于800MM)接口处漏水,大致流程:根据管道的内径,在工厂定制不锈钢压条和橡胶条,然后进入管道安装,先手工固定橡胶条,接着通过管道,用密封胶圈压住通风管道伸缩节,从而完成管道局部防渗,必要时还可以对管道渗漏处进行注浆处理

The expansion joint of the ventilation pipe is mainly used for water leakage at the interface of the large-diameter pipe (the pipe diameter is not less than 800mm). The general process: according to the inner diameter of the pipe, first customize the stainless steel strip and rubber strip in the factory, and then enter the pipe for installation. First fix the rubber strip manually, and then press the expansion joint of the ventilation pipe with the sealing rubber ring through the pipe, so as to complete the local anti-seepage of the pipe. If necessary, the leakage of the pipe can also be grouted
