Description

Wall bushing structure

Technical Field

The application relates to the technical field of building construction, in particular to a wall bushing structure.

Background

In the basement outer wall construction process, often because objective reasons such as design change or construction error lead to outer wall sleeve to leak to bury or bury less, in order to satisfy the practical function, need to open the hole on the outer wall a second time, bury the sleeve pipe through the wall, this often leads to having the gap between sleeve pipe and the wall body, and the water-proof effects is poor, leads to this position later stage to have great infiltration risk. Meanwhile, if the pipeline penetrating through the sleeve is a thermal pipeline, the plugging material between the traditional sleeve and the thermal pipeline can expand and move along with the thermal pipeline, so that a gap is generated to influence the waterproof effect.
