Description

Flexible waterproof sleeve

Technical Field

The utility model relates to the technical field of waterproof sleeves, in particular to a flexible waterproof sleeve.

Background

In building construction, when a pipe needs to pass through a wall, a ground, a roof or the like where waterproofing is required, a waterproof sleeve needs to be used.

The existing waterproof sleeve comprises three types of a flexible waterproof sleeve, a rigid waterproof sleeve and a rigid waterproof wing ring. The flexible waterproof sleeve is suitable for areas with earthquake fortification requirements, the wall penetrating positions of the pipelines can bear vibration and telescopic deformation of the pipelines or building (building) with strict waterproof requirements, the rigid waterproof sleeve is suitable for building (building) which does not bear the vibration and telescopic deformation of the pipelines at the wall penetrating positions of the pipelines, the rigid waterproof wing ring is suitable for building (building) which does not bear the vibration and telescopic deformation of the pipelines at the wall penetrating positions of the pipelines, and the rigid waterproof wing ring is suitable for updating and reforming the building (building) or the pipelines before the space at the wall penetrating positions of the pipelines is limited.

However, the existing waterproof sleeve is mostly suitable for the condition of penetrating one wall, when a pipeline needs to continuously penetrate through a plurality of walls, different walls can generate different sedimentation, and the pipeline is inevitably deformed due to longitudinal shearing force, and sealing failure and pipeline deformation can be caused, so that water leakage is caused. Although the flexible waterproof sleeve can generate corresponding deformation when uneven settlement occurs, in the existing flexible waterproof sleeve, a place between the pipeline and the sleeve is necessarily rigidly fixed, so that the same problem can occur when settlement occurs after the two sleeves are both rigidly connected with the same tank wall.

In view of this, the present inventors have made trial and error to design and a flexible waterproof sleeve according to production design experience in the field and related fields for many years, so as to solve the problems of the prior art.
