Flexible waterproof casing sealing skeleton structure type is mainly divided into rubber sealing ring and rubber sealing ring, which is commonly used rubber sealing skeleton, the main structure of O-type rubber sealing skeleton, mainly for a variety of conventional occasions sealing T-shaped structure, mainly for a variety of waterproof requirements of high construction projects, to provide good sealing application effect for the pipeline system.
Since static friction is greater than sliding friction, the roughness of the trench surface is generally less than that of the sliding surface, so the friction distribution also tends to keep the rubber garden stationary in the trench.
The gap between the flexible waterproof casing and the working tube is not uniform, and there are many reasons why the flexible waterproof casing causes distortion damage. The eccentricity is too large. Uneven diameter of the rubber ring section, due to the rubber ring a week more uneven friction, the rubber ring part of the friction is too large, twisted. Generally speaking, the smaller cross-sectional size of the rubber ring is prone to uneven friction. This is why the diameter of the twisted motion rubber ring is larger than the fixed rubber ring.
